Add Cell Selection And Reselection Information(ADD CELLSELRESEL)

Add cell selection and reselection information.

Description

Value range: 0~65535

Physical unit: None

Content: Uniquely identifying a cell

Recommended value: None

Value range: CPICH_ECNO(CPICH Ec/N0), CPICH_RSCP(CPICH RSCP)

Physical unit: None

Content: Measurement quantity of cell selection and reselection. It can be set to CPICH Ec/N0 or CPICH RSCP.

For detailed information of this parameter, refer to 3GPP TS 25.304.

Recommended value: CPICH_ECNO

Value range: 0~20

Physical value range: 0~40; step: 2

Physical unit: dB

Content: The hysteresis value of the serving FDD cells in idle mode in case the quality measurement for cell

selection and reselection is set to CPICH RSCP. It is related to the slow fading feature of the area where the cell is

located. The greater the slow fading variance is, the greater this parameter.

According to the R regulation, the current serving cell involves in cell selection after the measurement value is

added with the hysteresis value. The measurement hysteresis aims to prevent the ping-pong effect of the cell

reselection, which is caused by the slow fading when the UE is on the edge of the cell. The ping-pong effect may

trigger frequent location updates (idle mode), URA updates (URA_PCH), or cell updates (CELL_FACH, CELL_PCH),

and thus increase the load of network signaling and the consumption of UE batteries. Set a proper measurement

hysteresis to reduce as much as possible effect of the slow fading as well as ensuring timely cell updates of the

UE. According to the CPICH RSCP emulation report of inter-frequency hard handovers, the measurement

hysteresis ranges 4 dBm to 5 dBm and is set to 4 dBm by default when the slow fading variance is 8 dB and the

relative distance is 20 m. In the cells where the slow fading variance is low and the average moving speed of UEs

is high, for example the suburbs and countryside, reduce the measurement hysteresis to guarantee timely

location updates of UEs. The higher the measurement hysteresis is, the less likely it is for various types of cell

reselections to occur, and the better the slow fading resistance capability is, but the slower the system reacts to

the environment changes. For detailed information of this parameter, refer to 3GPP TS 25.304.

Value range: 0~20


Physical unit: dB.

Content: The hysteresis value of the serving FDD cells in connected mode in case the quality measurement for

cell selection and reselection is set to CPICH RSCP. It is related to the slow fading feature of the area where the

cell is located. The greater the slow fading variance is, the greater this parameter.














Recommended value: 2

Value range: {{0~20},{255}}


Physical unit: dB.

Content: The hysteresis value of the serving FDD cells in idle mode in case the quality measurement for cell

selection and reselection is set to CPICH Ec/No. It is related to the slow fading feature of the area where the cell

is located. The greater the slow fading variance is, the greater this parameter. It is optional. If it is not configured,

[Hysteresis 1] will be adopted as the value. This parameter is not configured when its value is 255.














Recommended value: the same as Qhyst1s for idle mode

Value range: {{0~20},{255}}.

Physical value range: 0~40; step: 2.

Physical unit: dB.

Content: The hysteresis value of the serving FDD cells in connected mode in case the quality measurement for

cell selection and reselection is set to CPICH Ec/No. It is related to the slow fading feature of the area where the

cell is located. The greater the slow fading variance is, the greater this parameter. This parameter is not

configured when its value is 255.














Recommended value:the same as Qhyst1s for connect mode.

Value range: 0~31

Physical unit: s

Content: If the signal quality (CPICH Ec/No measured by the UE) of a neighboring cell is better than that of the

serving cell during the specified time of this parameter, the UE reselects the neighboring cell. It is used to avoid

ping-pong reselection between different cells. Note that the value 0 corresponds to the default value defined in

the protocol.

Set the parameter as follows:

1. Ensure that the UE can reselect a cell when crossing the non-soft-switch area of the cell and that the UE timely

performs location updates, cell updates, or URA updates when necessary.

2. Ensure that the UE does not reselect a cell when it is in the soft-switch area of the cell. In this way, the

unnecessary location updates, cell updates, and URA updates are avoided.

3. Consider the difference between cells that cover different areas, for example the cells covering highways and

cells covering densely populated areas. TIf the parameter is set to a comparatively low value, the ping-pong

reselections may be caused. The parameter can be increased in populated area and reduced in high-speed

movement. If the parameter is set to a comparatively high value, the cell reselection delay may become

excessively high, and thus cell reselections may be affected.

For detailed information, refer to 3GPP TS 25.304.


Value range: -24~0

Physical unit: dB

Content: The minimum required quality threshold corresponding to CPICH Ec/No. The UE can camp on the cell

only when the measured CPICH Ec/No is greater than the value of this parameter. The higher the parameter

value is, the more difficult it is for the UE to reside in the cell. The lower parameter value is, the easier it is for

the UE to reside in the cell, but it is possible that the UE cannot receive the system messages that are sent

through the PCCPCH. For detailed information, refer to the 3GPP TS 25.304.

Recommended value: -18

Value range: -58~-13

Physical value range: -115~-25; step: 2 (-58:-115; -57:-113; ...; -13:-25 )

Physical unit: dBm

Content: The minimum required RX threshold corresponding to CPICH RSCP. The UE can camp on the cell only

when the measured CPICH RSCP is greater than the value of this parameter. The setting of Qrxlevmin should be

related to Qqualmin. The higher the parameter is, the more difficult it is for the UE to reside in the cell. The

lower parameter is, the easier it is for the UE to reside in the cell, but it is possible that the UE cannot receive the

system messages that are sent through the PCCPCH. For detailed information, refer to 3GPP TS 25.304.

Add cell oriented CAC algorithm parameters(ADD CELLCAC)

Function

Note

Parameter

Example

Function

Add cell-oriented Call Admission Control (CAC) algorithm parameters.

In actual operation, it is necessary to set the CAC algorithm parameters based on the network management experience and algorithm analysis results, so as to achieve the following purposes:

1. Set coverage ranges for various services: set the restrictions on the transmit power of different services to satisfy different coverage requirements according to the network planning. Note that the coverage specification must be taken into consideration together with the capacity specification.

2. Restrict services proportions in a cell: restrict the number of different services by setting different admission thresholds for conversational and other services, so as to ensure the priority of conversational service.

3. Optimize resource configuration (1): set different admission thresholds for conversational service, other services and the services in handover state, so as to ensure the handover success rate as well as the priority of conversational service.

4. Optimize resource configuration (2): reserve resources for UL/DL common channels so as to guarantee service transmission on the common channels.

There are 4 classes of services corresponding to different QoS requirements, as follows:

1. Conversational: This class corresponds to real-time services. The QoS requirement of this class is determined by people's sensory. It has a relatively looser BLER requirement, but strict transmission delay requirement. Typical services: AMR speech and video phone.

2. Streaming: This class corresponds to real-time streaming services, such as audio and video programs. It's unidirectionally transmitted and serves individual users. It has a relatively looser delay requirement than conversational, but the sequential relation should be ensured. Typical service: Video on demand.

3. Interactive: This class corresponds to data services, such as terminal browsing. It has a strict BLER requirement, and the transmission delay should be limited in a sensible range. Typical services: Web browsing and database retrieval.

4. Background: This class also corresponds to data services. It has a strict BLER requirement, but no transmission delay requirement. Typical services: SMS, E-mail delivery and data download.

Note

1. [Cell environment type] is set to TU generally. In most cases, this parameter should not be changed.

2. Following restriction must be satisfied:

triggered only the RSCP value of the used frequency is lower than this threshold. (Event 3A can be triggered




Physical unit: s.

Content: If the inter-RAT handover to a GSM cell fails, the possible reason is that this cell is overloaded.

Therefore, in the period specified by this parameter, the system will not send the inter-RAT handover request

to this cell.


Value range: 0~512.

Physical unit: s.

Content: If no inter-RAT handover occurs upon expiry of the inter-RAT measurement timer, the system stops

inter-RAT measurement and disables the compressed mode if enabled. If this parameter is 0, the system will

not start the inter-RAT measurement timer.
