Handover 2 Overview

2 Overview

The GSM network comprises multiple cells with continuous coverage. The handover technique is introduced into the GSM system to enable the users who are in motion to continue with the current call without interruption, thus optimizing the network performance.

During a handover, the MS and BTS in service measure the conditions of uplink and downlink radio links respectively, record the measurement results into measurement reports (MRs), and then send the MRs to the BSC. The BSC determines whether to trigger a handover based on the MRs and the actual conditions of the radio network.

Huawei handover algorithms (handover algorithm I and handover algorithm II) involve measurement and MR reporting, MR processing, handover decision, and handover execution.

Huawei handover algorithms apply to the handovers on TCHs as well as the handovers on SDCCHs.

You can determine the handover algorithm used in a cell through HOCTRLSWITCH.

Figure 2-1 shows the procedure for performing Huawei handover algorithms (including handover algorithm I and handover algorithm II).

Handover 2 Overview



2-3

In handover algorithm I, five types of handover decisions are defined:

Quick handover (including quick Power Budget(PBGT) handover and frequency offset handover). Good and stable services can be provided when the voice quality deteriorates during the fast movement of an MS. Quick handover is mainly applicable in the railway scenario.

Emergency handover. Emergency handover can ensure the call continuity when the radio condition severely deteriorates. Theoretically, the emergency handover has a bigger deviation than other handovers in terms of the selection of the target cell. In a normal cell, frequent emergency handovers should be avoided.

Enhanced dual-band network handover. In an enhanced dual-band network, the resources in the overlaid DCS1800 cell and underlaid GSM900 cell can be shared during the assignment and handover procedures. That is, the calls in the high-traffic GSM900 cell can be handed over to the low-traffic DCS1800 cell to balance traffic.

Load handover. Load handover enables the system load to be balanced among multiple cells so that the system performance can be ensured.

Normal handover. Normal handover ensures good services when an MS is moving.

Figure 2-3 shows the handovers provided in Figure 2-2 and their priorities in handover algorithm I.

Handover Execution (GBFD-117101 BTS power lift for handover)

BTS power lift for handover function determines whether the BTS of the serving cell transmits signals at the maximum power during a handover. The BSC maximizes the transmit power of the BTS before sending a handover command to the MS. The BSC does not adjust the BTS power during the handover to ensure the success of the handover.

Handover 3 Technical Description



3-1

3 Technical Description

3.1 Measurement Report Processing

This section describes the feature GBFD-110801 Processing of Measurement Report and GBFD-110802 Pre-processing of Measurement Report.

Measurement report processing involves measurement report interpolation and filtering.

NE Selection for Measurement Report Processing

The processing can be performed either on the BSC side or on the BTS side.

If BTSMESRPTPREPROC is set to No, then the processing is performed on the BSC side.

If BTSMESRPTPREPROC is set to Yes, then the processing is performed on the BTS side. By setting the parameters PRIMMESPPT, BSMSPWRLEV, and MRPREPROCFREQ, you can specify the contents of the MRs to be provided and the period during which the MRs are provided. This decreases the signaling traffic on the Abis interface and the traffic volume processed by the BSC.

Data Selection for Measurement Report

The MR can be classified into enhanced MR and normal MR. The parameter MEASURETYPE determines the type to be used.

In the MR, the TCH measurement of the serving cell is classified into FULL SET and SUB SET.

Measurement Report Interpolation

The neighboring cell indexes are found on the basis of the BCCH frequencies and BSICs provided by the MS. Then, the uplink and downlink measurement results are obtained from the measurement reports.

If measurement reports are issued continuously, they are directly added to the measurement report list.

If measurement reports are not issued continuously and the number of lost measurement reports is smaller than the value of MRMISSCOUNT, the system performs operations as follows:

− For the serving cell, the handover algorithm I performs the linear interpolation for the MRs. The lowest values are applied to the interpolation of MRs by the handover algorithm II according to the protocols; that is, level 0 (-110 dBm) and quality 7 are applied in the interpolation.

− For the neighboring cell, the lowest value is applied to the lost level value according to the protocols; that is, level 0 (-110 dBm) is applied in the interpolation.

If no MR is reported because the RX level in the neighboring cell is too low, level 0 (-110 dBm) is applied in the interpolation.

If measurement reports are not issued continuously and the number of lost measurement reports is greater than the value of MRMISSCOUNT, the previous measurement reports are discarded. When new measurement reports are issued, calculation is done again.

Measurement Report Filtering

Filtering is performed on measurement reports obtained continuously from the measurement report list. Averaging is performed on uplink/downlink RX level, uplink/downlink RX quality, Timing Advance (TA), Radio Quality Indication (RQI), BTS power, 2G neighboring cell level, Common Pilot Channel (CPICH), Received Signal Code Power (RSCP), and Ec/No of neighboring 3G cell. The averaging minimizes the effect on the result of handover decision due to sudden changes in the measurement values.

Power control compensation needs to be performed for the downlink RX level of the serving cell by the handover algorithm II. If you compare the RX level of the serving cell after the power control with that of all BCCH TRXs of the neighboring cell, there is no mapping between them. In situations where the cells overlap severely, the handover is easily triggered, thus causing the ping-pong handover. After the power control compensation is performed, the RX level of the serving cell can reflect the coverage condition of the BCCH TRX of the serving cell. The power control compensation of the serving cell is performed after the interpolation processing and before the filtering processing. In general, the compensation of power control is calculated by adding the downlink RX level of the serving cell and twice the current downlink transmit POWL of the BTS.

The number of consecutive measurement reports required for filtering is determined by the measurement object and channel type. See Table 3-1 for details.

If consecutive measurement reports are insufficient, the filtering fails. The handover decision is not performed.

3.2 Handover Preprocessing

Handover Penalty

According to the neighboring cell information in the measurement report and the parameters, the system performs handover preprocessing and adjusts the priorities of the neighboring cells.

The handover penalty is performed after successful fast-moving micro cell handover, TA handover, BQ handover, fast-moving micro cell handover, OL subcell to UL subcell handover within an enhanced concentric cell, and after the handover failures.

In handover algorithm II, in addition to the situations mentioned above, the handover penalty is also performed after successful or failed load handover and interference handover.

In handover decision procedure of handover algorithm II, the handover penalty is performed after the network characteristics adjustment and before the emergency handover decision.

After the quick handover, TA handover, Bad Quality (BQ) handover, or load handover (in handover algorithm II) is successfully performed, the penalty level is subtracted from the actual RX level of the original cell during the penalty period. Table 3-2 lists the parameters related to handover penalty.

LOADHOPENVALUE

After the fast-moving micro cell handover is successfully performed, penalty is performed on all the neighboring cells of the micro cell. Related parameters are SDPUNVAL and SPEEDPUNISHT.

If an MS fails to initiate an intra-cell AMR TCHF to TCHH handover, it cannot initiate another intra-cell AMR TCHF to TCHH handover within TIMEAMRFHPUNISH.

In handover algorithm II, after the interference handover is initiated, this handover is not allowed to be initiated again within INTERFEREHOPENTIME regardless of whether the handover is successful or not.

After the OL subcell to UL subcell handover within an enhanced concentric cell is successful, the handover from UL subcell to OL subcell is not allowed within UTOOHOPENTIME.

After the OL cell to UL cell handover in the enhanced dual-band network is successful, the handover from UL cell to OL cell is not allowed within HOPENALTYTIME.

After the handover fails, different penalties are performed on the target cell based on the causes:

− If the handover to a neighboring 2G or 3G cell fails, the actual RX level of the target cell is subtracted by FAILSIGSTRPUNISH for neighboring cell ranking during the penalty.

Based on the handover failure cause, the penalty time could be UMPENALTYTIMER, RSCPENALTYTIMER, or PENALTYTIMER.

− If the OL subcell to UL subcell handover within a concentric cell fails, the handover from OL subcell to UL subcell is not allowed within TIMEOTOUFAILPUN.

− If the UL subcell to OL subcell handover within a concentric cell fails, the handover from UL subcell to OL subcell is not allowed within TIMEUTOOFAILPUN.

Basic Ranking

Basic ranking is performed after handover penalty to generate a candidate cell list in descending order taking the following information into account: RX levels of the serving cell and neighboring cells carried in the MRs, hysteresis, usage of TCHs in the neighboring cells, and so on.

In the case of non-directed retry, if an MS in an external BSC cell occupies an SDCCH and INRBSCSDHOEN is set to No, then this cell should be removed from the candidate cell list. In other words, the handover to this external BSC cell is prohibited.

If a neighboring 2G cell and the serving cell are controlled by the same BSC and the TCH usage of the neighboring cell is 100%, then the neighboring cell should be removed from the candidate cell list; that is, the handover to this neighboring cell is prohibited.

If the downlink RX level of a neighboring 2G cell is lower than the sum of HOCDCMINDWPWR and MINOFFSET, then the neighboring cell should be removed from the candidate cell list; that is, the handover to this neighboring cell is prohibited.

If the uplink RX level of a neighboring 2G cell is lower than the sum of HOCDCMINUPPWR and MINOFFSET, then the neighboring cell should be removed from the candidate cell list; that is, the handover to this neighboring cell is prohibited.

If a neighboring 3G cell is an FDD cell, the cell is processed according to FDDREP:

− If FDDREP is set to Ec/N0, and the Ec/No of a neighboring cell is lower than MINECNOTHRES, the neighboring cell should be removed from the candidate cell list; that is, the handover to this neighboring cell is prohibited.

− If FDDREP is set to RSCP, and the RSCP of a neighboring cell is lower than MINRSCPTHRES, the neighboring cell should be removed from the candidate cell list; that is, the handover to this neighboring cell is prohibited.

If a neighboring 3G cell is a TDD cell and the RSCP after penalty is lower than the MINRSCPTHRES, the neighboring cell should be removed from the candidate cell list; that is, the handover to this neighboring cell is prohibited.

Calculate the difference between the downlink RX level of the neighboring cells and the downlink RX level of the serving cell. Based on the difference, rank the neighboring cells in descending order.

Network Characteristics Adjustment

Network characteristics adjustment is a process in which the position of each cell in the candidate cell list is determined based on the related network information. Network characteristics adjustment provides the final candidate cell list for handover decision.

After the network characteristics adjustment, the final candidate cell list (including neighboring cells and serving cell) is generated. The candidate cells are ranked in descending order by priority. Then, the handover decision procedure starts.

In handover algorithm II, the emergency handover decision is made after the network characteristics adjustment.

After the emergency handover decision, LOADHOPENVALUE is subtracted from the level of the original cell within LOADHOPENTIME if the load handover is successful. The level of the target cell changes after the penalty of load handover; then, the network characteristics needs to be readjusted.

In handover algorithm I, all related factors are adjusted in network characteristics adjustment phase; in handover algorithm II, some of the factors are adjusted before the emergency handover decision procedure is initiated.

3.3 Forced Handover

A forced handover does not require a handover decision.

A forced handover is triggered in the following scenarios:

If no TCH is available in the serving cell which the MS attempts to access and DIRECTRYEN is set to Yes, the BSC triggers a directed retry procedure.

When a BTS is under maintenance, the MSs served by the BTS should be handed over to the cells controlled by a functional BTS. This ensures that no call drop occurs during the BTS maintenance.

Directed Retry (GBFD-110607 Directed Retry)

When the MS initiates a call, after the BSC receives an ASSIGN REQ message from the MSC, the BSC determines an assignment mode based on the load of the serving cell.

Assignment mode is categorized into normal assignment procedure, mode modification procedure, and directed retry procedure. The commands issued by the BSC vary according to the procedure.

For a normal assignment procedure, the BSC activates a channel and issues a channel assignment command.

For a mode modification procedure, the BSC issues a mode modification command.

For a directed retry procedure, the BSC issues a handover command.

If the serving cell is so overloaded that new calls cannot be admitted or admitting new calls will affect ongoing services, the BSC triggers a directed retry procedure. By using the directed retry, the MS is handed over to the target cell and part of the traffic in the serving cell is distributed to the target cell. This avoids traffic congestion in the serving cell.

Figure 3-1 shows the procedure for a directed retry decision.

GSM BSS




3-7

As shown in Figure 3-1, directed retry is categorized into enhanced dual-band network directed retry and normal directed retry.

Enhanced Dual-Band Network Directed Retry

In an enhanced dual-band network, two cells form a group and the MS camps on one of the two cells. After the directed retry is triggered, the MS is handed over to the other cell. For details on the conditions of triggering an enhanced dual-band network directed retry, see sections 3.4.7 "Enhanced Dual-Band Network Handover" and 3.5.6 "Enhanced Dual-Band Network Handover."

Target Cell Selection in a Normal Directed Retry Procedure

The target cell must have the highest priority in the candidate cell list after handover preprocessing. In addition, the target cell must meet the following conditions:

The serving cell does not function as a target cell.

Load of the candidate neighboring cells ≤ DTLOADTHRED

In handover algorithm II, serving cell level < receive level of neighboring cells < serving cell level + DRHOLEVRANGE.

In handover algorithm I, receive level of neighboring cells ≥ MINPWRLEVDIRTRY.

If DRTAGCELLSEL is set to YES, the MS can be handed over to one of multiple target cells by using directed retry. If DRTAGCELLSEL is set to NO, the MS can be handed over to only one target cell. The number of available target cells is controlled by HOTRYCNT.

3.4 Handover Decision Based on Handover Algorithm I

This section describes the feature GBFD-110601 HUAWEI I Handover.

According to the emergency condition of an MS in the network, the handover decision based on handover algorithm I is made in the following order: quick handover, emergency handover, enhanced dual-band network handover, load handover, and normal handover.

Handover decision based on handover algorithm I involves the following procedures:

Determining whether the serving cell meets the triggering conditions

Selecting corresponding candidate cells

In handover algorithm I, HOOPTSEL specifies whether a neighboring 2G cell or a neighboring 3G cell is preferred.

When HOOPTSEL is set to Preference for 2G Cell:

A neighboring 2G cell is preferred. If the candidate cell list contains suitable neighboring 3G cells but no suitable neighboring 2G cells, a neighboring 3G cell is selected.




If the RX level of a candidate 2G cell is lower than or equal to HOPRETH2G, a neighboring 3G cell is preferred.

If the triggering conditions of emergency handover are met and there is at least one candidate cell, then the emergency handover timer NEWURGHOMININTV is started. Another emergency handover decision can be performed only when NEWURGHOMININTV times out.

Quick handover aims to increase the handover success rate of an MS moving at a high speed and to ensure the call continuity and low call drop rate. Quick handover applies to the scenario where an MS moves fast along an urban backbone road, a selected route, or a high-speed railroad.

Quick Handover Types

Quick handover consists of frequency offset handover and quick PBGT handover.

Frequency offset handover

Whether the MS is moving away from the serving cell is determined based on the frequency offset information provided by an MS moving at a high speed. Frequency offset handover decision is made according to the uplink/downlink RX level of the serving cell and the path loss of neighboring cells.

Quick PBGT handover

Quick PBGT handover decision is made according to the path loss of neighboring cells.

For quick handover, the handover response speed is enhanced by:

Accurately calculating the moving speed of the MS

Lifting the restriction on the interval between handover decisions

Reducing the number of measurement reports for the handover decision

Introducing the alpha filtering

Quick Handover Preparation

The preparation for quick handover involves the following aspects:

Frequency offset is decoded from the measurement report.

Frequency offset of the MS is obtained from the uplink measurement report that the BTS sends to the BSC.

Alpha filtering is performed on the measurement report.

Triggering Conditions

During handover decision, it is first determined whether the triggering conditions of frequency offset handover are met. When the BTS cannot send the frequency offset information or the reported frequency offset information is invalid, quick PBGT handover is triggered, provided that other conditions of frequency offset handover are met.

If QUICKHOEN is set to Yes, the triggering conditions of quick handover are as follows:

The MS is moving away from the serving cell (the frequency offset in the measurement result is a negative value) and the moving speed of the MS is greater than MOVESPEEDTHRES.

The filtered uplink level of the serving cell is lower than HOUPTRIGE.

The compensated downlink level of the serving cell is lower than HODOWNTRIGE.

The path loss of configured chain neighboring cells is lower than the specified threshold of the path loss of the serving cell. In other words, PBGT(n) is greater than or equal to 0.

The triggering conditions of quick handover are as follows:

If the last three conditions are met simultaneously, the decision is made as follows:

− If the first condition is met, a frequency offset handover is performed.

− If the first condition is not met, a quick PBGT handover is performed.

If all the last three conditions are not met, quick handover is not triggered.

Target Cell Selection

The target cell must be a chain neighboring cell of the serving cell. The target cell can be obtained through the setting of ISCHAINNCELL. If HODIRFORECASTEN is set to Yes, a neighboring cell in the moving direction of the MS is selected preferentially.

To forecast the moving direction of the MS, the direction of a chain neighboring cell (A or B) compared with the serving cell is specified by CHAINNCELLTYPE. If the number of times that the MS is handed over to neighboring cells in the same direction (B for example) is greater than or equal to HODIRLASTTIME when the handover time reaches HODIRSTATIME, then the MS is inferred to be moving towards the B direction. Subsequently, the MS is preferentially handed over to the neighboring cell whose CHAINNCELLTYPE is B.

Limitations

The limitations on quick handover are as follows:

The serving cell cannot be selected as the target cell.

The candidate cells for quick handover must be chain neighboring cells of the serving cell.

After a quick handover is successful, the penalty is performed on the original cell during the penalty time to prevent an immediate handover back to the original cell. The penalty time and penalty value are specified by TIMEPUNISH and HOPUNISHVALUE respectively.

3.4.2 TA Handover

TA handover is a type of emergency handover. The TA handover decision is made according to the TA value reported by the MS.

The TA value of a normal cell ranges from 0 to 63 and that of an extended cell ranges from 0 to 229. The TA can be stepped up or down in steps of 553.5 m. The TA value of 63 corresponds to a distance of 35 km.


TA handover is triggered when the following conditions are met:

TAHOEN is set to Yes.

Filtered TA value in the measurement report provided by the MS is greater than or equal to TALIMIT.

The TA handover can be triggered only when the preceding two conditions are met simultaneously.

From the perspective of the triggering conditions of TA handover, TA can be regarded as a limitation to the size of a cell.


The target cell should have the highest priority in the candidate cell list after handover preprocessing. In addition, the target cell should meet the following conditions:


If TALIMIT of a co-site neighboring cell is lower than or equal to the TALIMIT of the serving cell, a handover to the neighboring cell is prohibited.

If the triggering conditions of TA handover are met but the candidate 2G cells are not suitable, the following operations are performed:

If a neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to Yes, and if the MS supports the 2G/3G inter-RAT handover, the 2G/3G inter-RAT handover is performed.

If no neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to No, or if the MS does not support the 2G/3G inter-RAT handover, the decision on whether to initiate another type of emergency handover is made.

Limitations

After the TA handover is successful, the penalty is performed on the original cell. During TIMETAPUNISH, SSTAPUNISH is subtracted from the level of the original cell to prevent an immediate handover back to the original cell.

3.4.3 BQ Handover

BQ handover is a type of emergency handover in which the system makes the decision based on the uplink/downlink RX quality on the Um interface.

The RX quality is measured in Bit Error Rate (BER). The BSC measures the quality of a radio link based on the quality class in the measurement report. The probable cause of an increase in BER is that the signal power is too low or the channel interference increases.


If BQHOEN is set to Yes, the triggering conditions of BQ handover are as follows:

The uplink RX quality is greater than or equal to the uplink RX quality threshold of the serving cell.

The downlink RX quality is greater than or equal to the downlink RX quality threshold of the serving cell.

The BQ handover is triggered when either of the preceding conditions is met.

The parameters for specifying the uplink and downlink RX quality thresholds are as follows:

For non-AMR calls, the parameter for specifying the uplink RX quality threshold is ULQUALIMIT and the parameter for specifying the downlink RX quality threshold is DLQUALIMIT.

For AMR FR calls, the parameter for specifying the uplink RX quality threshold is ULQUALIMITAMRFR and the parameter for specifying the downlink RX quality threshold is DLQUALIMITAMRFR.

For AMR HR calls, the parameter for specifying the uplink RX quality threshold is ULQUALIMITAMRHR and the parameter for specifying the downlink RX quality threshold is DLQUALIMITAMRHR.



If the target cell is a neighboring cell, the RX level of the target cell must meet the following condition:

Filtered downlink RX level of the target cell > Filtered downlink RX level of the serving cell after compensation + (INTERCELLHYST of the serving cell configured for the neighboring cell - 64) - (BQMARGIN - 64)

In handover algorithm I, if there is only one cell in the candidate cell list and the cell is a neighboring cell, then the preceding condition need not be met.

In handover algorithm I, if there is no neighboring cell, INTRACELLHOEN is set to Yes, and the serving cell is not in the intra-cell handover penalty state, then the MS is handed over to the serving cell. A channel with different frequency band, different frequency, different TRX, or different timeslot is preferred (priority: different frequency band > different frequency > different TRX > different timeslot).

If the triggering conditions of BQ handover are met but the candidate 2G cells are not suitable, the following operations are performed:



Limitations

After the BQ handover is successful, the penalty is performed on the original cell. During TIMEBQPUNISH, SSBQPUNISH is subtracted from the level of the original cell to prevent an immediate handover back to the original cell.

3.4.4 Rapid Level Drop Handover

Rapid level drop handover is a type of emergency handover.

In edge handover and PBGT handover, the mean value filtering and P/N decision methods are not responsive to short-period rapid level drop. Therefore, to solve the rapid level drop problem, the finite impact response filtering can be performed on the original RX level. This filtering method is responsive to the rapid level drop based on the drop slope of the original RX level.


If ULEDGETHRES is set to Yes, the triggering conditions of rapid level drop handover are as follows:

Filtered uplink level < ULEDGETHRES

A1 x C(nt) + A2 x C(nt - t) + A3 x C(nt - 2t) + … + A8 x C(nt - 7t) < B

Here, A1 indicates FLTPARAA1, A2 indicates FLTPARAA2, A3 indicates FLTPARAA3, A4 indicates FLTPARAA4, A5 indicates FLTPARAA5, A6 indicates FLTPARAA6, A7 indicates FLTPARAA7, and A8 indicates FLTPARAA8.

B indicates FLTPARAB.



The target cell has a higher priority than the serving cell.


If the triggering conditions of rapid level drop handover are met but the candidate 2G cells are not suitable, the following operations are performed:

If a neighboring 3G cell is available, INTERRATOUTBSCHOEN is set to Yes, and the MS supports the 2G/3G inter-RAT handover, the 2G/3G inter-RAT handover is performed.

If no neighboring 3G cell is available, INTERRATOUTBSCHOEN is set to No, or the MS does not support the 2G/3G inter-RAT handover, the decision on whether to initiate another type of emergency handover is made.

3.4.5 Interference Handover

In handover algorithm I, interference handover is a type of emergency handover.

Interference handover helps protect the interfered calls and reduce the network interference. It is applicable to scenarios with interference.

In handover algorithm I, the difference between interference handover and BQ handover is that in BQ handover the bad signal quality resulting from both coverage and interference is checked. In interference handover, the bad signal quality resulting from coverage is not checked.


If INTERFHOEN is set to Yes, the triggering conditions of interference handover are as follows:

The filtered value of uplink RX quality is greater than or equal to the specified RX quality threshold at the current uplink RX level.

The filtered value of downlink RX quality is greater than or equal to the specified RX quality threshold at the current downlink RX level.

The interference handover is triggered if either of the previous conditions is met.


For non-AMR FR calls, the parameter for specifying the RX quality threshold is RXQUALn, where 1 ≤ n ≤ 12.

For AMR FR calls, the parameters for specifying the RX quality threshold are RXQUALn (1 ≤ n ≤ 12) and RXLEVOFF.

− If n = 1, the RX quality threshold is RXQUAL1.

− If 2 ≤ n ≤ 12, the RX quality threshold is RXQUALn + RXLEVOFF.


In handover algorithm I, the target cell should have the highest priority in the candidate cell list. In addition, the target cell should meet the following conditions:

If INTRACELLHOEN is set to Yes and the intra-cell handover penalty timer expires, the serving cell can be selected as the target cell.

When a number of consecutive intra-cell handovers occur, BANTIME is triggered and the intra-cell handover is prohibited

in the corresponding period.

If the filtered level of a neighboring cell after handover penalty ≥ HOTHRES of the neighboring cell + INTELEVHOHYST - 64, this neighboring cell can serve as the target cell.

If the triggering conditions of interference handover are met but the candidate 2G cells are not suitable, the following operations need to be performed:

If a neighboring 3G cell is available, INTERRATOUTBSCHOEN is set to Yes, and the MS supports the 2G/3G inter-RAT handover, the 2G/3G inter-RAT handover is performed.

If no neighboring 3G cell is available, INTERRATOUTBSCHOEN is set to No, or the MS does not support the 2G/3G inter-RAT handover, the decision on whether to initiate another type of emergency handover is made.

3.4.6 Handover Due to No Downlink Measurement Report

Handover due to no downlink measurement report is performed on the basis of the uplink quality. The purpose is to ensure the call continuity and minimize the possibility of call drops.

GSM BSS




3-13

Handover due to no downlink measurement report is generally caused by adverse radio environment on the uplink. In this case, the requirements of the filtering algorithm cannot be met, so other handover decisions cannot be performed.


In handover algorithm I, the triggering conditions of handover due to no downlink measurement report are as follows:

NODLMRHOEN is set to Yes.

There is no downlink information in the measurement report of the call.

The filtered value of uplink quality is greater than or equal to NODLMRHOQUALLIMIT.

The number of lost downlink MRs is smaller than NODLMRHOALLOWLIMIT.

For TCH, the number of saved MRs with uplink quality value is greater than DATAQUAFLTLEN; for SDCCH, the number of saved MRs with uplink quality value is greater than QLENSI.

In addition, the BSC triggers a handover due to no downlink measurement report when MRs of the serving cell keep lost for NODLMRHOLASTTIME within NODLMRHOSTATTIME.


In handover algorithm I, the conditions for selecting the target cell are as follows:

The ranked neighboring cells recorded in the last complete measurement report are saved as candidate cells.

Preferably a neighboring cell is selected as the target cell.

If no neighboring cell is available, the serving cell is selected as the target cell.

3.4.7 Enhanced Dual-Band Network Handover

Enhanced dual-band network handover is performed based on the traffic volume of the overlaid and underlaid cells and based on the receive level.

Enhanced dual-band network handover is classified into the following types:

Handover due to high load in the underlaid cell

Handover due to low load in the underlaid cell

Handover due to MS movement to the border of the overlaid cell

Triggering Conditions of Handover Due to High Load in the Underlaid Cell

The triggering conditions of the handover due to high load in the underlaid cell are as follows:

The two cells are in the enhanced dual-band network and OUTLOADHOENABLE is set to Yes.

The MS supports the frequency band on which the overlaid cell operates.

The handover due to high load in the underlaid cell is performed only on TCHs.

The load in the underlaid cell is higher than or equal to OUTGENOVERLDTHRED.

The load in the overlaid cell is lower than INNSERIOVERLDTHRED.

The system traffic volume is lower than or equal to EDBSYSFLOWLEV.

The current call is within the handover margin, and the INTOINNREXLEVTHRED plus the handover margin is greater than or equal to the receive level, which is also greater than or equal to the INTOINNREXLEVTHRED.

When all the preceding conditions are met, the handover due to high load in the underlaid cell is triggered.

If the load of the underlaid subcell in the cell is higher than or equal to OUTSERIOVERLDTHRED, then the handover margin is adjusted in a period of OUTLOADHOPERIOD subtracted by OUTLOADHOMODPERI. The step length for handover margin adjustment is specified by OUTLOADHOSTEP.

Triggering Conditions of Handover Due to Low Load in the Underlaid Cell

The triggering conditions of the handover due to low load in the underlaid cell are as follows:

The load in the underlaid cell is lower than OUTLOWLOADTHRED.


The current call is within the handover margin and the receive level is greater than or equal to OUTINNREXLEVTHRED.

When all the preceding conditions are met, the handover due to low load in the underlaid cell is triggered.

If the load of the underlaid subcell is lower than OUTLOWLOADTHRED for a specified period, then the handover margin is adjusted in a period of INNLOADHOPERI. The step length for handover margin adjustment is specified by INNLOADHOSTEP.

Triggering Conditions of Handover Due to MS Movement to the Border of the Overlaid Cell

The triggering conditions of the handover due to MS movement to the border of the overlaid cell are as follows:

SS(s) < Thdouter

SS(u) - SS(n) < ATCB_THRD - ATCB_HYST

Here,

− SS(s): specifies the filtering compensated downlink RX level in the serving cell.

− Thdouter: specifies OUTINNREXLEVTHRED.

− SS(u): specifies the downlink level (power compensation is performed on the downlink level based on the measurement) of the underlaid cell where the call is originated. If the SS(u) value cannot be obtained, you can infer that the decision of enhanced dual-band network handover is not performed and the decision condition is met by default.

− SS(n): The best neighboring cell is the one whose measured BCCH level is the highest among neighboring cells. SS(n) is the signal level of the best neighboring cell that operates on the same frequency band, locates at the same layer, and has the same priority as the underlaid cell but is not co-sited with the underlaid cell. If such a neighboring cell is not available, the value of SS(n) is -110 dBm.

− ATCB_THRD: specifies ATCBTHRED.

− ATCB_HYST: specifies ATCBHYST.

Handover due to MS movement to the border of the overlaid cell is triggered if either of the preceding conditions is met.

In the Adapter distance To Cell Border (ATCB) handover algorithm, the border between the overlaid and underlaid cells

is determined according to the signal strength of the serving cell and that of neighboring cells. If SS(s) = SS(n), the system considers that the MS is located at the border of the underlaid cell. If SS(s) - SS(n) > ATCB_THRD, the system considers that the MS is located in the coverage area of the overlaid cell. The coverage area of the overlaid cell is determined according to different networking and coverage conditions of the existing network. In addition, the overlaid cell of the serving cells and the overlaid cell of the neighboring cells will not overlap regardless of the distance between BTSs.

The handover margin specifies the range of signal level. In the case of overlaid/underlaid load handover on the enhanced dual-band network, the MSs whose downlink levels are within the handover margin are handed over level by level.


The requirements for target cell selection in the enhanced dual-band network are as follows:

For the handover due to high load in the underlaid cell, the MS must be handed over to the overlaid cell.

For the handover due to low load in the underlaid cell, the MS must be handed over to the underlaid cell.

For the handover due to MS movement to the border of the overlaid cell, the MS is handed over to the neighboring cell that ranks first among neighboring cells. The MS should not be handed over to the cell that ranks after the serving cell. Generally, the target cell is the underlaid cell. The target cell can also be another neighboring cell.

Limitations

The limitations on the handover due to high load in the underlaid cell are as follows:

If the cell where the call is located is on an enhanced dual-band network, CELLINEXTP is set to Extra(Extra).

The OUTLOADHOENABLE parameter should be set.

The maximum range of the handover margin is from 63 to INTOINNREXLEVTHRED. The MS with the highest receive level is handed over first.

The limitations on the handover due to low load in the underlaid cell are as follows:

If the cell where the call is located is on the enhanced dual-band network, CELLINEXTP is set to Inner(Inner).

The INNLOADHOEN parameter should be set.

The maximum range of the handover margin is from 63 to OUTINNREXLEVTHRED. The MS with the lowest receive level is handed over first.

The limitations on the handover due to MS movement to the border of the overlaid cell are as follows:


Impact of the Enhanced Dual-Band Network Handover on the Existing Algorithm

The impact of the enhanced dual-band network handover on the existing algorithm is as follows:

On the enhanced dual-band network, the MS should not be handed over to a cell in the same underlaid/overlaid cell group when the load handovers between the overlaid cell and the underlaid cell (specified by OUTLOADHOENABLE and INNLOADHOEN) are allowed. This is to prevent a load handover of a normal cell from colliding with a load handover between the overlaid cell and the underlaid cell on the network.

The PBGT handover algorithm may cause inter-cell handover; thus, the MS should not be handed over to the cell in the same group in the case of PBGT handover between cells on the enhanced dual-band network.

3.4.8 Load Handover

In the network, some cells carry heavy load whereas the overlapping upper-layer cells and the neighboring cells may carry light load. To balance the load of these cells, the load handover is required.

In a load handover procedure, some load in heavy-load cells is switched to light-load cells. Meanwhile, the load in neighboring cells is not switched to heavy-load cells.

Load handover can be performed between cells at different layers. Figure 3-2 shows the details.

For details about the inter-RAT load handover, see the Interoperability Between GSM and WCDMA Parameter Feature Description.

Figure 3-2 Load handover between cells

a heavy load

A cell with

A cell with

A cell with

A cell with

A cell with

A cell with

a light load

To perform load sharing, increase DLEDGETHRES so that the load at the border of a cell is switched to a neighboring cell with light load.

Whether a cell carries heavy load or light load is determined by the traffic volume in the cell, that is whether the traffic volume (generally TCH usage) in the cell exceeds the preset threshold.

If the traffic volume in a cell is greater than TRIGTHRES, you can infer that the load in this cell is heavy. The load handover algorithm needs to be enabled.

If the traffic volume in a cell is lower than LoadAccThres, you can infer that the load in this cell is light and the cell can receive load from the heavy-load cells.

Load handover may lead to many handovers. Therefore, the load of the system CPU should be considered before load handover is performed. In other words, the system traffic volume should be taken into account. In addition, to prevent too many MSs from being handed over at a time, load handover is performed step by step. In other words, the edge handover threshold is increased on the basis of LOADHOSTEP (CLS_Ramp) and LOADHOPERIOD (CLS_Period). When the increase in the edge handover threshold equals LOADOFFSET (CLS_Offset), the edge handover threshold is not increased any more. See Figure 3-3 for details.

If LoadHoEn is set to Yes, the triggering conditions of load handover are as follows:

The CPU usage of the system is less than or equal to SYSFLOWLEV.

The current load of the serving cell is greater than or equal to TRIGTHRES.


The conditions for selecting the target cell are as follows:

Filtered RX level after handover penalty ≥ HOTHRES + INTELEVHOHYST - 64


If the target cell and the serving cell are in the same BSC, a load handover is performed when the current load of the target cell is lower than LoadAccThres.

If the target cell and the serving cell are not in the same BSC, a load handover is performed when the load of the target cell is lower than LoadAccThres and OutBscLoadHoEn is set to Yes.

Examples

The system assigns MSs to different load handover margins based on the downlink RX level. The load handover algorithm is used to hand over the MSs out of a cell step by step.

1. The MSs in load handover margin 1 are handed over to the neighboring cells. Load handover margin 1 specifies the area where the downlink level ranges from DLEDGETHRES to the sum of DLEDGETHRES and LOADHOSTEP.

2. After a LOADHOPERIOD elapses, the MSs in load handover margin 2 are handed over to the neighboring cells. The load handover margin 2 specifies the area where the downlink level ranges from DLEDGETHRES to the sum of DLEDGETHRES and (2 x LOADHOSTEP).

3. The load handover stops when the traffic volume in the cell is less than or equal to TRIGTHRES.

The load handover is performed step by step to prevent call drops caused by a sudden increase in CPU load or the congestion in the target cell.

3.4.9 Enhanced Load Handover

Like the load handover, the enhanced load handover is used to balance load of cells in a network. Unlike the load

handover, the enhanced load handover considers the handover quality and the load in the target cell before the

handover is performed. In this way, the possibility of low level and congestion due to heavy load in the target cell

after the handover is minimized. The enhanced load handover is applicable to the scenario where multiple base

stations are located at the same place.

Triggering Conditions of Enhanced Load Handover

If LOADHOAD is set to YES, the triggering conditions of an enhanced load handover are as follows:

The CPU usage of the current system is lower than or equal to SYSFLOWLEV.

The load of the serving cell is higher than TRIGTHRES.

Here, the load of the serving cell is expressed in the percentage of the channels that are occupied. If the built-in PCU is used, the calculation method of the cell load depends on the setting of LOADSTATYPE. The setting of the parameter determines whether the dynamic PDCHs that can be preempted are considered as occupied channels.

When LOADSTATYPE is set to 0, the dynamic PDCHs that can be preempted are not considered in the cell load.

When LOADSTATYPE is set to 1, the dynamic PDCHs that can be preempted are considered as occupied TCHs in the cell load.

When LOADSTATYPE is set to 2, the dynamic PDCHs that can be preempted are considered as idle TCHs in the cell load.

The number of the dynamic PDCHs that can be preempted depends on the number of dynamic PDCHs and DYNCHNPREEMPTLEV. The number of dynamic PDCHs is the total number of channels whose CHTYPE is set to FULLTCH.

If the external PCU is used, the number of the dynamic PDCHs that can be preempted is always zero. The setting of LOADSTATYPE is thus irrelevant to calculation of the cell load.


When a candidate cell satisfying the following conditions is found and not a single MS within the range specified by LOADHOUSRRATIO is handed over to the target cell, further search of the target cell is stopped and current traffic is handed over to the candidate cell. The detailed conditions for selecting the target cell are as follows:

The value of LOADHOPBGTMARGIN is not 0 and the path loss in the serving cell minus that in the target cell is larger than LOADHOPBGTMARGIN.

The load of the target cell is lower than LoadAccThres.

The receive level of the target cell is higher than HOTHRES of the target cell plus INTELEVHOHYST of the handover from the serving cell to the target cell.

Of all the MSs that are within the range specified by LOADHOUSRRATIO and meet the preceding conditions, only one MS can initiate the handover at a time. This regulation prevents too many MSs from being handed over to the target cell at one time and thus avoids congestion in the target cell.

3.4.10 Edge Handover

Edge handover is performed on the basis of receive level.

To trigger an edge handover, the receive level of the target cell should be at least one hysteresis value (specified by INTERCELLHYST - 64) greater than the receive level of the serving cell.


If FRINGEHOEN is set to Yes, the triggering conditions of edge handover are as follows:

Either of the following conditions is met.

− The filtered downlink RX level of the serving cell after compensation is lower than DLEDGETHRES.

− The filtered uplink RX level of the serving cell after compensation is lower than ULEDGETHRES.

RX level of the neighboring cell > RX level of the serving cell + INTERCELLHYST-64

An edge handover is triggered when the P/N criterion is met, that is, when the previous conditions are met for EDGELAST1 within EDGESTAT1.

Figure 3-4 shows the edge handover.

The target cell should have the highest priority among the candidate cells. In addition, it should meet the following conditions:


After cells are ranked, the target cell must have a higher priority than the serving cell.

A cell becomes the target cell if the previous conditions are met for EDGEADJLASTTIME within EDGEADJSTATTIME.

If the triggering conditions of edge handover are met but the candidate 2G cells are not suitable, the following operations are performed:


If no neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to No, or if the MS does not support the 2G/3G inter-RAT handover, the decision on whether to initiate another type of handover is made.

3.4.11 Fast-Moving Micro Cell Handover

Fast-moving micro cell handover is performed from a micro cell to a macro cell according to the relative speed of an MS so that the number of handovers can be minimized.

Fast-moving micro cell handover applies to the following scenarios:

If an MS is moving fast in a micro cell, it is handed over to a macro cell.

To prevent an MS that is moving fast in a macro cell from entering a micro cell, time penalty is performed on the micro cell so that the fast-moving MS camps on the macro cell.

Figure 3-5 shows the fast-moving micro cell handover.

Figure 3-5 Fast-moving micro cell handover

Umbrella cell

Micro cell


If QCKMVHOEN is set to Yes, the handover decision procedure of fast-moving micro cell handover is as follows:

1. When the triggering conditions of edge handover or PBGT handover are met, the fast-moving micro cell handover decision is started.

2. When the period during which the MS camps on the serving cell is shorter than QCKTIMETH, the number of cells through which the fast-moving MS passes is incremented by one.

The cell counted by the system must locate at a layer lower than layer 4. In other words, it must be a non-Umbrella cell.

3. When the number of cells that the MS passes in fast movement reaches QCKSTATCNT, the fast-moving micro cell handover is triggered if the number of cells that the MS passes in fast movement counted by the system is greater than or equal to QCKTRUECNT.


In handover algorithm I, the target cell should have the highest priority among the candidate cells. In addition, the target cell should meet the following conditions:

The target cell must be at layer 4, that is, Umbrella cell.

Filtered RX level of the target cell ≥ HOTHRES + INTELEVHOHYST - 64

Limitations

After the fast-moving micro cell handover is successful, the penalty is performed on all the neighboring micro cells. During SPEEDPUNISHT, SDPUNVAL is subtracted from the RX level of every neighboring micro cell.

Cell Layer and Cell Priority

With Huawei multiband handover algorithm, a proper traffic volume distribution can be realized among multiple frequency bands.

Huawei multiband handover algorithm divides cells into four layers, with 16 priorities at each layer. The LAYER parameter specifies at which layer a cell is located. This algorithm is applicable to complex networking scenarios. Figure 3-6 shows the cell layers.

In Huawei multiband handover algorithm, a GSM network covering a certain area is divided into four layers, which are:

Layer 4: Umbrella cell. The umbrella cells are generally GSM900 cells having the wide coverage feature. It also implements fast MS connection.

Layer 3: Macro cell. The macro cells are generally GSM900 cells, which are commonly used in current GSM system and serve majority of subscribers.

Layer 2: Micro cell. The micro cells are generally DCS1800 cells having the small coverage feature. They enable capacity expansion.

Layer 1: Pico cell. The Pico cells are generally DCS1800 cells, which are used in hot spots and blind spots.

The cell at the lower layer has a higher priority.

PRIOR controls handover between cells at the same layer. Each layer has 16 priorities, numbered 1-16 respectively. A high value indicates a low priority. If the cells at the same layer have different priorities, a cell with a lower priority value has a higher priority. PRIOR along with CELLLAYER determines the priority of a cell. The priority affects the sequence of neighboring cells for handover.

3.4.12 Inter-Layer Handover

Inter-layer handover is a type of normal handover. It is used to enable the micro cells at low layers (the priority is high) to absorb traffic volume.

To balance the traffic volume flexibly and to meet the requirements of different network topologies, the GSM network is divided into several layers. See 3.4.11 Fast-Moving Micro Cell Handover for details.


If LEVHOEN is set to Yes, the triggering conditions of inter-layer handover are as follows:

The layer at which the target cell is located has a higher priority than the layer at which the serving cell is located.

The load of the serving cell is higher than LAYHOLOADTH.

The requirements for target cell selection are as follows:

The triggering conditions are met.


The target cell has the highest priority in the candidate cell list.

3.4.13 PBGT Handover

PBGT handover is a type of normal handover.


If PBGTHOEN is set to Yes, the triggering conditions of PBGT handover are as follows:

The target cell and the serving cell are at the same layer and have the same priority.

The following condition is met for PBGTLAST within PBGTSTAT:

(MIN (MS_TXPWR_MAX, P) – RXLEV_DL – PWR_DIFF) – (MIN (MS_TXPWR_MAX (n), P) – RXLEV_NCELL (n) ) > PBGT_HO_MARGIN

Here,

− RXLEV_DL: indicates the filtered downlink RX level of the serving cell.

− MS_TXPWR_MAX: indicates the maximum allowed transmit power of an MS in the serving cell.

− MS_TXPWR_MAX (n): indicates the maximum allowed transmit power of an MS in neighboring cell n.

− RxLev_NCELL (n): indicates the downlink receive level in neighboring cell n.

− PWR_DIFF: indicates the difference between the maximum downlink transmit power in the serving cell due to power control and the actual downlink transmit power in the serving cell.

− P: indicates the maximum transmit power of an MS.

− PBGT_HO_MARGIN: indicates the PBGTMARGIN of the serving cell configured for neighboring cells minus 64.

The PBGT handover can be triggered only when all the previous conditions are met.


The target cell should meet the following conditions:

The target cell and the serving cell are at the same layer and have the same priority.

The AMR handover in handover I algorithm consists of the AMR TCHF-TCHH handover and AMR TCHH-TCHF handover algorithm. The AMR TCHF-TCHH handover is conducted based on cell load and RQI, whereas the AMR TCHH-TCHF handover is conducted based on RQI.

The conversion formula between RQI and C/I is RQI = 2 x C/I.

Triggering Conditions of AMR TCHF-TCHH Handover

The triggering conditions of AMR TCHF-TCHH handover are as follows:

INTRACELLFHHOEN is set to Yes.

The target call is an AMR call.

The half-rate function must be enabled in the cell where the call is initiated.

The full-rate speech version 3 and half-rate speech version 3 must be supported by the cell where the call is initiated.

The type of channel specified by the MSC during a call can be changed during a handover.

For AMR FR calls, when the parameter AMRTCHHPRIORALLOW is set to ON(On), TCHF-to-TCHH handover is triggered only when the cell load is greater than the value of the parameter AMRTCHHPRIORLOAD and the proportion of AMR HR users is smaller than the value of the parameter ALLOWAMRHALFRATEUSERPERC.

For AMR FR calls, when the parameter AMRTCHHPRIORALLOW is set to OFF(Off), TCHF-to-TCHH handover is triggered only the proportion of AMR HR users is smaller than the value of the parameter ALLOWAMRHALFRATEUSERPERC.

The call occupies the full-rate TCH. The RQI/2 is greater than INHOF2HTH and the cell load is greater than AMRTCHHPRIORLOAD.

For an AMR FR call, the AMR TCHF-TCHH handover can be performed if the preceding conditions are met for INFHHOLAST within INFHHOSTAT.

Triggering Conditions of AMR TCHH-TCHF Handover

The triggering conditions of AMR TCHH-TCHF handover are as follows:

INTRACELLFHHOEN is set to Yes.

The target call is an AMR call.

The half-rate function must be enabled in the cell where the call is initiated.

The full-rate speech version 3 and half-rate speech version 3 must be supported by the cell where the call is initiated.

The type of channel specified by the MSC during a call can be changed during a handover.

The call occupies the half-rate TCH. The RQI/2 is smaller than INHOH2FTH, and the proportion of half-rate TCHs in the cell is smaller than ALLOWAMRHALFRATEUSERPERC.

For an AMR HR call, the AMR TCHH-TCHF handover can be performed if the preceding conditions are met for INFHHOLAST within INFHHOSTAT.


The AMR handover is an intra-cell handover. Therefore, only the serving cell can be selected as the target cell.

SDCCH handover is a process in which the MS is handed over from an SDCCH to another SDCCH in an immediate assignment. SDCCH handover helps improve the access success rate of the MSs on the edge of the network, thus improving the network QoS.

The principle of SDCCH handover is the same as that of TCH handover. Regarding procedure, an SDCCH handover involves measurement and MR reporting, MR processing, handover decision, and handover execution.

Whether an SDCCH handover can be performed is controlled by the SIGCHANHOEN parameter. If an inter-BSC SDCCH handover is required, both SIGCHANHOEN and INRBSCSDHOEN should be set to YES(Yes).

The handover decision algorithm for SDCCH handover is different from that for TCH handover in the following ways:

The algorithms for the following handovers support SDCCH handover:

Quick handover, TA handover, BQ handover, rapid level drop handover, interference handover, handover due to no downlink measurement report, edge handover, and fast-moving micro cell handover

The algorithms for the following handovers do not support SDCCH handover:

Dual-band network handover, load handover, inter-layer handover, PBGT handover, AMR handover, better 3G cell handover, concentric cell handover, and tight BCCH handover

3.4.16 Other Handovers

Other handovers here refer to better 3G cell handover and tight BCCH handover.

3.5 Handover Decision Based on Handover Algorithm II

This section describes the feature GBFD-510501 HUAWEI II Handover.

Handover decision based on handover algorithm II is made in the following order: forced handover, emergency handover, intra-cell handover, and inter-cell handover.

Handover decision based on handover algorithm II involves the following procedures:

Determining whether the serving cell meets the triggering conditions

Selecting corresponding candidate cell list for each handover type

Performing the comprehensive decision and determining the candidate neighboring cells

The procedure for performing comprehensive decision based on handover results and determining the candidate neighboring cells is as follows:

1. The BSC selects a handover type with the highest priority from all the handovers that can be performed on each neighboring cell.

The handover priority is as follows:

− Forced handover, emergency handover, and interference handover have a high priority. Figure 3-7 shows the details.

2. The BSC ranks the candidate cells according to the network characteristics adjustment algorithm and then generates the final candidate cell list. Every neighboring cell in the candidate cell list has its own handover decision. Neighboring 2G cells and neighboring 3G cells are ranked separately.

3. In handover algorithm II, HOOPTSEL specifies whether a neighboring 2G or a neighboring 3G cell is preferred.

− When HOOPTSEL is set to Preference for 2G Cell:


− When HOOPTSEL is set to Preference for 3G Cell:


− When HOOPTSEL is set to Preference for 2G Cell By Threshold:

If the RX level of a candidate 2G cell is lower than or equal to HOPRETH2G, a neighboring 3G cell is preferred.

When a neighboring 3G cell is preferred among the candidate cells, the priority of 3G better cell handover is the lowest.

If the triggering conditions of emergency handover are met and there is at least one candidate cell, then the emergency handover timer NEWURGHOMININTV is started. Another emergency handover decision can be performed only when NEWURGHOMININTV times out.

3.5.1 Quick Handover

Quick handover aims to increase the handover success rate of an MS moving at a high speed and to ensure the call continuity and low call drop rate. Quick handover applies to the scenario where an MS moves fast along an urban backbone road, a selected route, or a high-speed railroad.

Quick Handover Types

Quick handover consists of frequency offset handover and quick PBGT handover.

Frequency offset handover

Whether the MS is moving away from the serving cell is determined based on the frequency offset information provided by an MS moving at a high speed. Frequency offset handover decision is made according to the uplink/downlink RX level of the serving cell and the path loss of neighboring cells.

Quick PBGT handover

Quick PBGT handover decision is made according to the path loss of neighboring cells.

For quick handover, the handover response speed is enhanced by:

Accurately calculating the moving speed of the MS

Lifting the restriction on the interval between handover decisions

Reducing the number of measurement reports for the handover decision

Introducing the alpha filtering

Quick Handover Preparation

The preparation for quick handover involves the following aspects:

Frequency offset is decoded from the measurement report.

Frequency offset of the MS is obtained from the uplink measurement report that the BTS sends to the BSC.

Alpha filtering is performed on the measurement report.


During handover decision, it is first determined whether the triggering conditions of frequency offset handover are met. When the BTS cannot send the frequency offset information or the reported frequency offset information is invalid, quick PBGT handover is triggered, provided that other conditions of frequency offset handover are met.

If QUICKHOEN is set to Yes, the triggering conditions of quick handover are as follows:

The MS is moving away from the serving cell (the frequency offset in the measurement result is a negative value) and the moving speed of the MS is greater than MOVESPEEDTHRES.

The filtered uplink level of the serving cell is lower than HOUPTRIGE.

The compensated downlink level of the serving cell is lower than HODOWNTRIGE.

The path loss of configured chain neighboring cells is lower than the specified threshold of the path loss of the serving cell. In other words, PBGT(n) is greater than or equal to 0.

The triggering conditions of quick handover are as follows:

If the last three conditions are met simultaneously, the decision is made as follows:

− If the first condition is met, a frequency offset handover is performed.

− If the first condition is not met, a quick PBGT handover is performed.

If all the last three conditions are not met, quick handover is not triggered.





GSM BSS




3-28


The target cell must be a chain neighboring cell of the serving cell. The target cell can be obtained through the setting of ISCHAINNCELL. If HODIRFORECASTEN is set to Yes, a neighboring cell in the moving direction of the MS is selected preferentially.

To forecast the moving direction of the MS, the direction of a chain neighboring cell (A or B) compared with the serving cell is specified by CHAINNCELLTYPE. If the number of times that the MS is handed over to neighboring cells in the same direction (B for example) is greater than or equal to HODIRLASTTIME when the handover time reaches HODIRSTATIME, then the MS is inferred to be moving towards the B direction. Subsequently, the MS is preferentially handed over to the neighboring cell whose CHAINNCELLTYPE is B.

Limitations

The limitations on quick handover are as follows:


The candidate cells for quick handover must be chain neighboring cells of the serving cell.

After a quick handover is successful, the penalty is performed on the original cell during the penalty time to prevent an immediate handover back to the original cell. The penalty time and penalty value are specified by TIMEPUNISH and HOPUNISHVALUE respectively.

3.5.2 TA Handover

TA handover is a type of emergency handover. The TA handover decision is made according to the TA value reported by the MS.

The TA value of a normal cell ranges from 0 to 63 and that of an extended cell ranges from 0 to 229. The TA can be stepped up or down in steps of 553.5 m. The TA value of 63 corresponds to a distance of 35 km.


TA handover is triggered when the following conditions are met:

TAHOEN is set to Yes.

Filtered TA value in the measurement report provided by the MS is greater than or equal to TALIMIT.

The TA handover can be triggered only when the preceding two conditions are met simultaneously.

From the perspective of the triggering conditions of TA handover, TA can be regarded as a limitation to the size of a cell.


The target cell should have the highest priority in the candidate cell list after handover preprocessing. In addition, the target cell should meet the following limitations:


If TALIMIT of a co-site neighboring cell is lower than or equal to the TALIMIT of the serving cell, a handover to the neighboring cell is prohibited.

In handover algorithm II, a cell becomes the target cell for TA handover if the previous conditions are met for TALASTTIME within TASTATTIME.

If the triggering conditions of TA handover are met but the candidate 2G cells are not suitable, the following operations are performed:













../RNCParaHtml/mbsc/m-para/g2gncell_talasttime.html

../RNCParaHtml/mbsc/m-para/g2gncell_tastattime.html

GSM BSS




3-29



Limitations

After the TA handover is successful, the penalty is performed on the original cell. During TIMETAPUNISH, SSTAPUNISH is subtracted from the level of the original cell to prevent an immediate handover back to the original cell.

3.5.3 BQ Handover

BQ handover is a type of emergency handover in which the system makes the decision based on the uplink/downlink RX quality on the Um interface.

RX quality is represented by BER. The BSC measures the quality of a radio link based on the quality class in the measurement report. The probable cause of an increase in BER is that the signal power is too low or the channel interference increases.


If BQHOEN is set to Yes, the triggering conditions of BQ handover are as follows:

The uplink RX quality is greater than or equal to the uplink RX quality threshold of the serving cell.

The downlink RX quality is greater than or equal to the downlink RX quality threshold of the serving cell.

The BQ handover is triggered when either of the preceding conditions is met.


For non-AMR calls, the parameter for specifying the uplink RX quality threshold is ULQUALIMIT and the parameter for specifying the downlink RX quality threshold is DLQUALIMIT.

For AMR FR calls, the parameter for specifying the uplink RX quality threshold is ULQUALIMITAMRFR and the parameter for specifying the downlink RX quality threshold is DLQUALIMITAMRFR.

For AMR HR calls, the parameter for specifying the uplink RX quality threshold is ULQUALIMITAMRHR and the parameter for specifying the downlink RX quality threshold is DLQUALIMITAMRHR.



In handover algorithm II, the serving cell cannot be selected as the target cell.

The RX level of target cell must meet the following conditions:

− The serving cell and the target cell work in the same frequency band.

Filtered downlink RX level of the target cell > Filtered downlink RX level of the serving cell after compensation + (INTERCELLHYST of the serving cell configured for the neighboring cell - 64) - (BQMARGIN - 64)

− The serving cell works in GSM900 and the target cell works in DCS1800.

Filtered downlink RX level of the target cell ≥ HOTHRES + (LEVHOHYST - 64).















../RNCParaHtml/mbsc/m-para/gcellhobasic_levhohyst.html

GSM BSS




3-30

− The serving cell works in DCS1800 and the target cell works in GSM900.

There is no constraint on the target cell in this condition.

In handover algorithm II, a cell becomes the target cell for BQ handover if the previous conditions are met for BQLASTTIME within BQSTATTIME.

If the triggering conditions of BQ handover are met but the candidate 2G cells are not suitable, the following operations are performed:



Limitations

After the BQ handover is successful, the penalty is performed on the original cell. During TIMEBQPUNISH, SSBQPUNISH is subtracted from the level of the original cell to prevent an immediate handover back to the original cell.

3.5.4 Interference Handover

Interference handover is a type of intra-cell handover in handover algorithm II.

Interference handover helps protect the interfered calls and reduce the network interference. It is applicable to scenarios with interference.

In handover algorithm II, the BQ handover is a type of emergency handover and the interference handover is a type of intra-cell handover.


If INTRACELLHOEN is set to Yes and INTERFHOEN is set to Yes, the triggering conditions of interference handover are as follows:

The filtered value of uplink RX quality is greater than or equal to the specified RX quality threshold at the current uplink RX level.

The filtered value of downlink RX quality is greater than or equal to the specified RX quality threshold at the current downlink RX level.

In handover algorithm II, the interference handover is triggered when the previous conditions are met for INTERFERELASTTIME within INTERFERESTATTIME.


For non-AMR FR calls, the parameter for specifying the RX quality threshold is RXQUALn, where 1 ≤ n ≤ 12.

For AMR FR calls, the parameters for specifying the RX quality threshold are RXQUALn (1 ≤ n ≤ 12) and RXLEVOFF.

− If n = 1, the RX quality threshold is RXQUAL1.

− If 2 ≤ n ≤ 12, the RX quality threshold is RXQUALn + RXLEVOFF.


In handover algorithm II, only the serving cell can be selected as the target cell.

Limitations

In handover algorithm II, if an interference handover is initiated, it cannot be initiated again within INTERFEREHOPENTIME regardless of whether the handover is successful.

3.5.5 Handover Due to No Downlink Measurement Report

Handover due to no downlink measurement report is performed on the basis of the uplink quality. The purpose is to ensure the call continuity and minimize the possibility of call drops.

Handover due to no downlink measurement report is generally caused by adverse radio environment on the uplink. In this case, the requirements of the filtering algorithm cannot be met, so other handover decisions cannot be performed.


In handover algorithm II, the triggering conditions of handover due to no downlink measurement report are as follows:

NODLMRHOEN is set to Yes.

There is no downlink information in the measurement report of the call.

The number of lost downlink MRs is smaller than NODLMRHOALLOWLIMIT.

For TCH, the number of saved MRs with uplink quality value is greater than DATAQUAFLTLEN; for SDCCH, the number of saved MRs with uplink quality value is greater than QLENSI.

The filtered value of uplink RX quality is greater than or equal to ULQUALIMIT.

− For AMR FR calls, the corresponding parameter is ULQUALIMITAMRFR.

− For AMR HR calls, the corresponding parameter is ULQUALIMITAMRHR.

In addition, the BSC triggers a handover due to no downlink measurement report when MRs of the serving cell keep lost for NODLMRHOLASTTIME within NODLMRHOSTATTIME.


In handover algorithm II, the conditions for selecting the target cell are as follows:

The ranked neighboring cells recorded in the last complete measurement report are saved as candidate cells.

Only a neighboring cell can serve as the target cell.

RX level in neighboring cell > Filtered RX level in serving cell + (INTERCELLHYST - 64) - (BQMARGIN - 64)

A neighboring cell serves as the target cell if the previous conditions are met for ULBQLASTTIME within ULBQSTATTIME.

3.5.6 Enhanced Dual-Band Network Handover

Enhanced dual-band network handover is performed based on the traffic volume of the overlaid and underlaid cells and based on the receive level.

Enhanced dual-band network handover is classified into the following types:

Handover due to high load in the underlaid cell

Handover due to low load in the underlaid cell

Handover due to MS movement to the border of the overlaid cell

Triggering Conditions of Handover Due to High Load in the Underlaid Cell

The triggering conditions of the handover due to high load in the underlaid cell are as follows:

The two cells are in the enhanced dual-band network and OUTLOADHOENABLE is set to Yes.

The MS supports the frequency band on which the overlaid cell operates.

The handover due to high load in the underlaid cell is performed only on TCHs.

The load in the underlaid cell is higher than or equal to OUTGENOVERLDTHRED.

The load in the overlaid cell is lower than INNSERIOVERLDTHRED.


The current call is within the handover margin, and the INTOINNREXLEVTHRED plus the handover margin is greater than or equal to the receive level, which is also greater than or equal to the INTOINNREXLEVTHRED.

When all the preceding conditions are met, the handover due to high load in the underlaid cell is triggered.

If the load of the underlaid subcell is higher than or equal to OUTSERIOVERLDTHRED, then the handover margin is adjusted in a period of OUTLOADHOPERIOD subtracted by OUTLOADHOMODPERI. The step length for handover margin adjustment is specified by OUTLOADHOSTEP.

Triggering Conditions of Handover Due to Low Load in the Underlaid Cell

The triggering conditions of the handover due to low load in the underlaid cell are as follows:

The load in the underlaid cell is lower than OUTLOWLOADTHRED.


The current call is within the handover margin and the receive level is greater than or equal to OUTINNREXLEVTHRED.

When all the preceding conditions are met, the handover due to low load in the underlaid cell is triggered.

If the load of the underlaid subcell is lower than OUTLOWLOADTHRED for a specified period, then the handover margin is adjusted in a period of INNLOADHOPERI. The step length for handover margin adjustment is specified by INNLOADHOSTEP.

Triggering Conditions of Handover Due To MS Movement in the Overlaid Subcell

The triggering conditions of the handover due to MS movement in the overlaid subcell are described as follows:

SS(s) < Thdouter

SS(u) - SS(n) < ATCB_THRD - ATCB_HYST

Here,

− SS(s): specifies the filtering compensated downlink RX level in the serving cell.

− Thdouter: specifies OUTINNREXLEVTHRED.

− SS(u): specifies the downlink level (power compensation is performed on the downlink level based on the measurement) of the underlaid subcell where the call is originated. If the SS(u) value cannot be obtained, you can infer that the decision of enhanced dual-band network handover is not performed and the decision condition is met by default.


















GSM BSS




3-33

− SS(n): The best neighboring cell is the one whose measured BCCH level is the highest among neighboring cells. SS(n) is the level value of such an optimum neighboring cell that is on the same frequency band, layer, and level with the underlaid subcell but is not co-sited with the underlaid subcell. If such a neighboring cell is not available, the value of SS(n) is -110 dBm.

− ATCB_THRD: specifies ATCBTHRED.

− ATCB_HYST: specifies ATCBHYST.

Handover due to MS movement in the overlaid subcell is triggered if either of the preceding conditions is met.

For the ATCB handover algorithm, the boundaries of the overlaid and underlaid subcells are determined according to

the relative value between the signal strength of serving cell and that of neighboring cell. When SS(s) is equal to SS(n), the system considers that it is the boundary point of the underlaid subcell. When the value of SS(s) subtracted by SS(n) is greater than ATCB_THRD, it is the coverage area of the overlaid subcell. The coverage area of the overlaid subcell is determined according to different networking and coverage conditions of the existing network. In addition, the overlaid subcell of serving cell and the overlaid subcell of neighboring cells will not overlap regardless of the distance between BTSs.

The handover margin specifies the range of signal level. In the case of overlaid/underlaid load handover on the enhanced dual-band network, the MSs whose downlink levels are within the handover margin are handed over level by level.


The requirements for target cell selection in the enhanced dual-band network are as follows:

For the handover due to high load in the underlaid cell, the MS must be handed over to the overlaid cell.

For the handover due to low load in the underlaid cell, the MS must be handed over to the underlaid cell.

For the handover due to MS movement in the overlaid subcell, the MS must be handed over to the underlaid cell.

Limitations

The limitations on the handover due to high load in the underlaid cell are as follows:

If the cell where the call is located is on an enhanced dual-band network, CELLINEXTP is set to Extra(Extra).

The OUTLOADHOENABLE parameter should be set.

The maximum range of the handover margin is from 63 to INTOINNREXLEVTHRED. The MS with the highest receive level is handed over first.

The limitations on the handover due to low load in the underlaid cell are as follows:


The INNLOADHOEN parameter should be set.

The maximum range of the handover margin is from 63 to OUTINNREXLEVTHRED. The MS with the lowest receive level is handed over first.

The limitations on the handover due to MS movement in the overlaid subcell are described as follows:

The cell where the call is located is on the enhanced dual-band network. CELLINEXTP is set to Inner(Inner).










GSM BSS




3-34

Impact of the Enhanced Dual-Band Network Handover on the Existing Algorithm

The impact of the enhanced dual-band network handover on the existing algorithm is as follows:

On the enhanced dual-band network, the MS should not be handed over to a cell in the same underlaid/overlaid cell group when the load handovers between the overlaid cell and the underlaid cell (specified by OUTLOADHOENABLE and INNLOADHOEN) are allowed. This is to prevent a load handover of a normal cell from colliding with a load handover between the overlaid cell and the underlaid cell on the network.

3.5.7 Load Handover

In handover algorithm II, load handover is not decided independently.

In handover algorithm II, the load handover decision is made in network adjustment phase. The selection of target cell should be processed by the better cell handover. That is, the load handover is triggered when the triggering conditions of load handover and better cell handover are met simultaneously.

See 3.4.8 Load Handover for the triggering conditions of load handover. See 3.5.10 Better Cell Handover for the triggering conditions of better cell handover.

The ranges of load handover margins are defined as follows:

Load handover margin 1 specifies the area where the downlink level ranges from INTERCELLHYST minus LOADHOSTEP to INTERCELLHYST.

Load handover margin 2 specifies the area where the downlink level ranges from INTERCELLHYST minus LOADHOSTEP x 2 to INTERCELLHYST.

Load handover margin 1 specifies the area where the downlink level ranges from DLEDGETHRES to the sum of DLEDGETHRES and LOADHOSTEP.

3.5.8 Edge Handover

Edge handover is performed on the basis of receive level.

To trigger an edge handover, the receive level of the target cell should be at least one hysteresis value (specified by INTERCELLHYST - 64) greater than the receive level of the serving cell.


If FRINGEHOEN is set to Yes, the triggering conditions of edge handover are as follows:

Either of the following conditions is met.

− The filtered downlink RX level of the serving cell after compensation is lower than DLEDGETHRES.

− The filtered uplink RX level of the serving cell after compensation is lower than ULEDGETHRES.

RX level of the neighboring cell > RX level of the serving cell + INTERCELLHYST - 64

An edge handover is triggered when the P/N criterion is met, that is, when the previous conditions are met for EDGELAST within EDGESTAT.

Figure 3-9 shows the edge handover.

The target cell should have the highest priority among the candidate cells. In addition, it should meet the following conditions:



A cell becomes the target cell if the previous conditions are met for EDGEADJLASTTIME within EDGEADJSTATTIME.

If the triggering conditions of edge handover are met but the candidate 2G cells are not suitable, the following operations are performed:


If no neighboring 3G cell is available, if INTERRATOUTBSCHOEN is set to No, or if the MS does not support the 2G/3G inter-RAT handover, the decision on whether to initiate another type of handover is made.

3.5.9 Fast-Moving Micro Cell Handover

Fast-moving micro cell handover is performed from a micro cell to a macro cell according to the relative speed of an MS so that the number of handovers can be minimized.

Fast-moving micro cell handover applies to the following scenarios:

If an MS is moving fast in a micro cell, it is handed over to a macro cell.

To prevent an MS that is moving fast in a macro cell from entering a micro cell, time penalty is performed on the micro cell so that the fast-moving MS camps on the macro cell.

Figure 3-10 shows the fast-moving micro cell handover.





GSM BSS




3-36

Figure 3-10 Fast-moving micro cell handover

Umbrella cell

Micro cell


If QCKMVHOEN is set to Yes, the handover decision procedure of fast-moving micro cell handover is as follows:

1. When the triggering conditions of edge handover or PBGT handover are met, the fast-moving micro cell handover decision is started.

2. When the period during which the MS camps on the serving cell is shorter than QCKTIMETH, the number of cells through which the fast-moving MS passes is incremented by one.

The cells counted by the system must locate at a layer lower than layer 4. In other words, they must be non-Umbrella cells.

3. When the number of cells that the MS passes in fast movement reaches QCKSTATCNT, the fast-moving micro cell handover is triggered if the number of cells that the MS passes in fast movement counted by the system is greater than or equal to QCKTRUECNT.


In handover algorithm II, the target cell should have the highest priority among the candidate cells. In addition, the target cell should meet the following conditions:

The target cell must be at layer 4, that is, Umbrella cell.

Filtered RX level of the target cell ≥ HOTHRES + INTELEVHOHYST - 64

A neighboring cell serves as the target cell if the previous conditions are met for HCSLASTTIME within HCSSTATTIME.

Limitations

After the fast-moving micro cell handover is successful, the penalty is performed on all the neighboring micro cells. During SPEEDPUNISHT, SDPUNVAL is subtracted from the RX level of every neighboring micro cell.

Cell Layer and Cell Priority

Through Huawei multiband handover algorithm, a proper traffic volume distribution can be realized among multiple frequency bands.

Huawei multiband handover algorithm divides cells into four layers, with 16 priorities at each layer. The LAYER parameter specifies at which layer a cell is located. This algorithm is applicable to complex networking scenarios. Figure 3-11 shows the cell layers.

In Huawei multiband handover algorithm, a GSM network covering a certain area is divided into four layers, which are:

Layer 4: Umbrella cell. The umbrella cells are generally GSM900 cells having the wide coverage feature. It also implements fast MS connection.

Layer 3: Macro cell. The macro cells are generally GSM900 cells, which are commonly used in current GSM system and serve majority of subscribers.

Layer 2: Micro cell. The micro cells are generally DCS1800 cells having the small coverage feature. They enable capacity expansion.

Layer 1: Pico cell. The Pico cells are generally DCS1800 cells, which are used in hot spots and blind spots.

The cell at the lower layer has a higher priority.

PRIOR controls handover between cells at the same layer. Each layer has 16 priorities, numbered 1-16 respectively. A high value indicates a low priority. If the cells at the same layer have different priorities, a cell with a lower priority value has a higher priority. PRIOR along with CELLLAYER determines the priority of a cell. The priority affects the sequence of neighboring cells for handover.

3.5.10 Better Cell Handover

Better cell handover is an optimization of inter-layer handover and PBGT handover in handover algorithm I. Better cell handover is specific to handover algorithm II.


If BETTERCELLHOEN is set to Yes, the triggering conditions of better cell handover are as follows:





../RNCParaHtml/mbsc/m-para/gcellhobasic_bettercellhoen.html

GSM BSS




3-38

If PATHLOSSHOEN is set to Yes, path loss is taken into consideration during the sorting of the serving cell and target cells. If PATHLOSSHOEN is set to No, path loss is not taken into consideration during the sorting of the serving cell and target cells.

If the serving cell is in the candidate cell list, then the priorities of the target cells must be higher than the priority of the serving cell after the sorting.

If the serving cell is not in the candidate cell list, then the target cells must meet the following conditions:

− LoadHoEn is set to NO, or LoadHoEn is set to YES but the load in the serving cell is lower than TRIGTHRES.

− If the serving cell and the target cells are at the same layer and have the same priority, the following conditions must be met:

SS_DL(N) - SS_DL(S) > H - 64

SS_DL(N) indicates the filtered BCCH receive level of a target cell. SS_DL(S) indicates the compensated receive level on the downlink TCH after filtration. H indicates INTERCELLHYST of the serving cell over the neighboring cell.

Negative handover is a type of better cell handover. When INTERCELLHYST is set to a value smaller than 64, the value of H – 64 is negative. In this case, even if the downlink receive level in a candidate cell is lower than the downlink receive level in the serving cell, a negative handover to the candidate cell can be performed.

− If the serving cell and the target cells are at different layers but have the same priority, the following conditions must be met:

SS_DL(N) ≥ T_layer(N) + H_layer(S)

SS_DL(N) indicates the filtered BCCH receive level of a target cell. T_layer(N) indicates HOTHRES of the target cell. H_layer(S) indicates INTELEVHOHYST of the serving cell.

− If LoadHoEn is set to YES and the load in the serving cell is higher than TRIGTHRES, better cell handover can be triggered.

A neighboring cell becomes a target cell if the preceding conditions are met for BETTERCELLLASTTIME during BETTERCELLLASTTIME.


The requirements for target cell selection are as follows:



3.5.11 Handover Between a Full-Rate TCH and a Half-Rate TCH

This section describes the feature GBFD-115522 Dynamic HR/FR Adaptation.

Handover between a full-rate TCH and a half-rate TCH performs decision based on handover algorithm II.

Types of handover between a full-rate TCH and a half-rate TCH are as follows:

AMR TCHF-TCHH handover and non-AMR TCHF-TCHH handover

The purpose is to absorb more MSs and to reduce the cell congestion if the cell load is high.

AMR TCHH-TCHF handover and non-AMR TCHH-TCHF handover

The purpose is to improve the speech quality of the call if the cell load is low.

Only the serving cell can be selected as the target cell of the TCHF-TCHH handover.

3.5.12 SDCCH Handover

This section describes the feature GBFD-110608 SDCCH Handover.

SDCCH handover is a process in which the MS is handed over from an SDCCH to another SDCCH in an immediate assignment. SDCCH handover helps improve the access success rate of the MSs on the edge of the network, thus improving the network QoS.

The principle of SDCCH handover is the same as that of TCH handover. Regarding procedure, an SDCCH handover involves measurement and MR reporting, MR processing, handover decision, and handover execution.

Whether an SDCCH handover can be performed is controlled by the SIGCHANHOEN parameter. If an inter-BSC SDCCH handover is required, both SIGCHANHOEN and INRBSCSDHOEN should be set to YES(Yes).

The handover decision algorithm for SDCCH handover is different from that for TCH handover in the following ways:

The algorithms for the following handovers support SDCCH handover:

quick handover, TA handover, BQ handover, interference handover, handover due to no downlink measurement report, edge handover, and fast-moving micro cell handover

The algorithms for the following handovers do not support SDCCH handover:

enhanced dual-band network handover, load handover, better cell handover, handover between a full-rate TCH and a half-rate TCH, better 3G cell handover, concentric cell handover, and tight BCCH handover

3.5.13 Other Handovers

Other handovers here refer to better 3G cell handover and tight BCCH handover.

SET GCELLHOEDBPARA(Optional)

Meaning: Hysteresis in the distance between the boundary of the overlaid subcell and the boundary of the underlaid subcell. This parameter helps to adjust "Distance Between Boudaries of Subcells" and thus to prevent ping-pong handover between the overlaid and underlaid subcells. Assume that the signal strength of the serving cell is SS(s) and that the signal strength of the neighbor cell is SS(n). If SS(s) - SS(n) < "Distance Between Boudaries of Subcells" - "Distance Hysteresis Between Boudaries", the MS is handed over from the overlaid subcell to the underlaid subcell.

Meaning: Distance between the boundary of the overlaid subcell and the boundary of the underlaid subcell. This parameter specifies the difference between the coverage of the overlaid subcell and the coverage of the underlaid subcell in the concentric cell or dual-frequency network scenario. The boundaries of the overlaid and underlaid subcells are determined according to the relative value between the signal strength of the serving cell and the signal strength of the neighbor cell. Assume that the signal strength of the serving cell is SS(s) and that the signal strength of the neighbor cell is SS(n). If SS(s) = SS(n), the MS is on the boundary of the underlaid subcell. If SS(s) - SS(n) > "Distance Between Boudaries of Subcells", the MS is in the coverage of the overlaid subcell.

Main BCCH+SDCCH/8+extended BCCH (BCH)+TCH+extended BCCH (BCH)+3TCH

The BCCHs in a cell need to be configured according to the number of channels in the cell and the paging capacity in the location area.

The main and combined BCCHs shall always be configured in timeslot 0. An extended BCCH can be configured only in timeslot 2, 4, or 6. If an extended BCCH is configured, the CCCH parameter in the system message data needs to be configured accordingly. For example, if an extended BCCH is configured in timeslot 2, the CCCH parameter in the system message data needs to be configured as two uncombined CCCHs.

To enable cell broadcast in a cell, add a CBCH to the cell during the radio channel configuration. In the case of SDCCH/8 cell broadcast, set this parameter to SDCCH_CBCH. You can change a TCH into SDCCH+CBCH or the original SDCCH into SDCCH+CBCH. In the case of SDCCH/4 cell broadcast, set this parameter to BCCH_CBCH.
