2 Overview
2.1 IntroductionCall reestablishment is a function by which radio links (RLs) are reestablished when a serviceinterruption or an access failure occurs in temporary coverage holes and in tunnels, elevators,and buildings that cause significant signal quality fluctuation.
Call reestablishment can be initiated by a UE or the RAN.
l Call reestablishment initiated by a UE: The UE sends a call reestablishment request to thenetwork to restore services upon detecting a downlink RL out-of-synchronization problemor a signaling radio bearer (SRB) reset.
l Call reestablishment initiated by the RAN: After the RAN detects a service interruption oran access failure (possibly due to a signaling radio bearer (SRB) reset or an uplink RL out-of-synchronization problem) before the UE does, the RAN stops the UE's downlink RLsets to enable the UE to detect downlink RL out-of-synchronization problem as soon aspossible. Upon detecting a downlink RL out-of-synchronization problem, the UE sends acall reestablishment request to the RAN to restore services.
This document describes only call reestablishment initiated by the RAN.
2.2 BenefitsCall reestablishment initiated by the RAN improves user experience.
2.3 Architecture
Causes That Can Trigger Call Reestablishment
The causes that can trigger call reestablishment after a service interruption or an access failureare as follows:
l RL out-of-synchronization problem
l SRB reset
WCDMA RANCall Reestablishment Feature Parameter Description 2 Overview
Issue 02 (2014-09-15) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.

l Air-interface process timeout
l Air-interface process overlap
l PS TRB reset
Processes That Can Trigger Call Reestablishment
The preceding causes are involved in the following processes:
l Soft handover
l Physical channel reconfiguration
– Physical channel reconfiguration during hard handovers
– Physical channel reconfiguration for the starting of the compressed mode
– Physical channel reconfiguration during code tree reshuffling
– Physical channel reconfiguration during serving cell updates
– Physical channel reconfiguration for adjustments of the UE Rx-Tx timing
– Physical channel reconfiguration during power adjustments for HSUPA channels
l Inter-RAT handover
l RB setup
l RB release
l RB reconfiguration
l Measurement control command issuing
l PS data transmission
l Security mode setup
Before releasing RLs due to any of the causes, the RAN detects the service interruption or accessfailure and initiates call reestablishment.

NOTE
The cause "RL out-of-synchronization problem" can trigger call reestablishment in processes not listed inTable 2-1. The other causes can trigger call reestablishment only in processes listed in Table 2-1.
Service/Process/Cause Switches of Call Reestablishment
Call reestablishment is controlled by the following switches:
l Service switches
Service switches include a CS service switch and a PS service switch. Enable a serviceswitch before enabling a process or cause switch.
l Process switches
Each triggering process listed in Table 2-1 has a switch.
l Cause switches
Only the "RL out-of-synchronization problem," "SRB reset," and "air-interface processoverlap" causes have a switch.
Call reestablishment can be triggered only when required switches are enabled. For details aboutservice/process/cause switches of call reestablishment, see descriptions in the follow-upchapters.
A UE can only reestablish a service on the DCH instead of the FACH if related parameters forthe UE are set as follows:
l The TAC_FUNC(BSC6900,BSC6910) parameter is set to Special_User_Enhance.
WCDMA RANCall Reestablishment Feature Parameter Description 2 Overview

l SPECUSER_REEST_TO_FACH_LIMITATION under theSpecUserFunctionSwitch4(BSC6900,BSC6910) parameter is set to on.
NOTE
If RL_REEST_PS_ON_FACH_SWITCH under theOptimizationSwitch3 parameter is set to on, a singlePS service is reconfigured with a FACH during call reestablishment, regardless of which cause triggerscall reestablishment and which process is involved. Reconfiguring PS services with FACHs may causecongestions in the FACHs, resulting in an increase of the service drop rate on common channels.

3 Uplink RL Out of Synchronization
3.1 Uplink RL Out of Synchronization Detection
3.1.1 Detection PrincipleThe NodeB monitors uplink RL quality. If the number of "out-sync" indications received by theNodeB reaches the value of the NOUTSYNCIND(BSC6910,BSC6900) parameter, the NodeBstarts the TRlFailure(BSC6900,BSC6910) timer. How the detection process continues dependson the situation:
l If the number of "in-sync" indications received by the NodeB reaches the value of theNINSYNCIND(BSC6900,BSC6910) parameter before the TRlFailure(BSC6900,BSC6910) timer expires, the NodeB stops and resets the TRlFailure(BSC6900,BSC6910) timer.
l If the number of "in-sync" indications received by the NodeB does not reach the value ofthe NINSYNCIND(BSC6900,BSC6910) parameter before the TRlFailure(BSC6900,BSC6910) timer expires, the NodeB considers that an RL out-of-synchronization problem has occurred and identifies the RL set where the problem islocated. (An RL set contains all the RLs of a UE under a NodeB.)
NOTE
The higher the value of the NOUTSYNCIND(BSC6900,BSC6910) parameter, the harder it will be for RLout-of-synchronization problems to be triggered. The higher the value of the NINSYNCIND(BSC6900,BSC6910) parameter, the harder it will be for RLs to be synchronized. If either parameter is setto a high value, RLs may stay on the verge of RL out-of-synchronization problem for a long time, and userexperience will be poor for both CS and PS services. Set NOUTSYNCIND(BSC6900,BSC6910) to a valuesmaller than the default one and NINSYNCIND(BSC6900,BSC6910) to a value higher than the defaultone. This way, RL out-of-synchronization problems are easily triggered for call reestablishment to improveuser experience.
The default value of NOUTSYNCIND(BSC6900,BSC6910) is 50 and NINSYNCIND(BSC6900,BSC6910) is 5.
When a UE's uplink RL sets are all out of synchronization, the events that occur depend on thesituation:

l If the call reestablishment function is not enabled, the call drops or the UE access finallyfails.
l If the call reestablishment function is enabled, the RNC activates a synchronization timer.
Table 3-1 shows the mapping between services, OptimizationSwitch(BSC6900,BSC6910):RL_RESTORE_SWITCH switch status, and synchronization timers.
Table 3-1 Mapping between services, OptimizationSwitch:RL_RESTORE_SWITCH status,and synchronization timers

CS services Off RlRstrTmr(BSC6900,BSC6910)

PS services Off RlRstrTmr(BSC6900,BSC6910)
On RlRstrTmr(BSC6900,BSC6910)
If the NodeB does not detect uplink RL synchronization before the timer expires, callreestablishment is initiated.
NOTE
Enable the OptimizationSwitch(BSC6900,BSC6910):RL_RESTORE_SWITCH switch for CS servicesso that uplink and downlink RLs are monitored by the same synchronization timer.
When the OptimizationSwitch(BSC6900,BSC6910):RL_RESTORE_SWITCH switch is enabled, thesynchronization timer used to initiate RL establishment is RlRstrTmr(BSC6900,BSC6910). The T313(BSC6900,BSC6910) timer is used only when the UE's RL sets are all out of synchronization.
3.1.2 Switches for Call Reestablishment Triggered by an RL Out-of-Synchronization Problem
To enable the call reestablishment function triggered by an RL out-of-synchronization problem,enable the service, process, and cause switches listed in Table 3-2.

Enabling a process switch allows RL out-of-synchronization problems to trigger callreestablishment in the related process. However, RL out-of-synchronization problems cantrigger call reestablishment in processes that are not controlled by the process switchesmentioned in this document.
NOTE
The service switch for CS+PS combined services is the same as that for CS services.
When call reestablishment is triggered for CS+PS combined services, calls are reestablished for both CSand PS services.

3.2.1 TriggeringCall reestablishment triggered by an uplink RL out-of-synchronization problem can beperformed under the same RNC or under different RNCs over the Iur interface.
Under the Same RNCAs mentioned in section 3.1 Uplink RL Out of Synchronization Detection, if the NodeB doesnot detect uplink RL synchronization before the RlRstrTmr(BSC6900,BSC6910) or T313(BSC6900,BSC6910) timer expires, the RNC sends to the NodeB the Radio Link ActivationCommand message containing the information element (IE) "deactivate." Upon receiving themessage, the NodeB stops downlink power transmission for the UE's RL sets. Then, the RNCstarts the timers for call reestablishment (CSRLReEstCellUpdateTmr(BSC6900,BSC6910)timer for CS services and PSRLReEstCellUpdateTmr(BSC6900,BSC6910) timer for PSservices).
l If the RNC does not receive the Cell Update message from the UE before the timers expire,the call drops or UE access fails.
l If the RNC receives the Cell Update message from the UE before the timers expire, theRNC stops the timers and initiates call reestablishment.
Figure 3-1 shows the signaling procedure for call reestablishment triggered by an uplink RLout-of-synchronization problem under the same RNC.

Figure 3-2 Call reestablishment triggered by an uplink RL out-of-synchronization problemunder different RNCs over the Iur interface
Call reestablishment triggered by an uplink RL out-of-synchronization problem under the sameRNC is similar to that triggered by an uplink RL out-of-synchronization problem under differentRNCs. The main differences between the two processes are as follows:
l In the former process, the RNC sends the Radio Link Activation Command to the NodeB.
l In the latter process, the SRNC sends the Radio Link Deletion Request message to theDRNC, and upon receiving the Radio Link Deletion Response message from the NodeB,the DRNC waits for the UE's Cell Update message.
In Figure 3-2, NodeB (Cell A) is under the SRNC and NodeB (Cell B) is under the DRNC.Before the uplink RL out-of-synchronization problem, the UE has established an RL with eachNodeB. After the uplink RL out-of-synchronization problem, the UE attempts to establish a newRL only with NodeB (Cell B).
3.2.2 ImplementationFigure 3-3 shows how call establishment is implemented.

Figure 3-3 Flowchart for call reestablishment
The call reestablishment process is implemented as follows:
1. After the NodeB stops downlink power transmission for a UE's RLs, the UE starts the T313(BSC6900,BSC6910) timer if the number of "out-sync" indications received consecutivelyfrom Layer 1 reaches the value of the N313(BSC6900,BSC6910) parameter.

Issue 02 (2014-09-15) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.
18
NOTE
The higher the value of the N313(BSC6900,BSC6910) parameter, the harder it will be for the UE todetect an RL out-of-synchronization problem and the longer the UE may stay on the verge of RLout-of-synchronization problem.
2. If the number of "in-sync" indications received consecutively from Layer 1 does not reachthe value of the N315(BSC6900,BSC6910) parameter before the T313(BSC6900,BSC6910) timer expires, the UE transmits the Cell Update message with thecause value "Radio Link Failure" to the RNC for call reestablishment. Meanwhile, the UEstarts the T302(BSC6900,BSC6910) timer as well as the T314(BSC6900,BSC6910) timerfor CS services or the T315(BSC6900,BSC6910) timer for PS services.
3. If the UE does not receive the Cell Update Confirm message from the RAN side after theT302(BSC6900,BSC6910) timer expires, the UE retransmits the Cell Update message untilthe T314(BSC6900,BSC6910)/T315(BSC6900,BSC6910) timer expires: (The number ofretransmissions is determined by the value of the T302(BSC6900,BSC6910) parameter.)
l If faulty RLs are restored before T314(BSC6900,BSC6910)/T315(BSC6900,BSC6910)expires, the call reestablishment is successful. Interrupted services are restored or UE accesssucceeds.
l If faulty RLs are not restored before T314(BSC6900,BSC6910)/T315(BSC6900,BSC6910) expires, the call reestablishment fails. Services are released or UEaccess fails.
NOTE
Set the T313(BSC6900,BSC6910), N313(BSC6900,BSC6910), N315(BSC6900,BSC6910), and T314(BSC6900,BSC6910) parameters so that UEs can quickly detect RL out-of-synchronization problem.
Set the timer for RAB assignment on the CN side during call reestablishment to a value greater than theRB setup response timer (RbSetupRspTmr(BSC6900,BSC6910)) plus the timerCSRLReEstCellUpdateTmr(BSC6900,BSC6910) (for CS services) or PSRLReEstCellUpdateTmr(BSC6900,BSC6910) (for PS services).
Set the security mode response timer on the CN side to a value greater than the security mode timer(RRCSECRTMODECMPTMR(BSC6900,BSC6910)) plus the timer T314(BSC6900,BSC6910) on theRNC side.
Set the timer for a response to the Relocation Command message that is sent by the CN during inter-RAThandovers to a value greater than the call reestablishment timer.
l For CS services, set the timer to a value greater than CSRLReEstCellUpdateTmr(BSC6900,BSC6910).
l For PS services, set the timer to a value greater than PSRLReEstCellUpdateTmr(BSC6900,BSC6910).

l Synchronization times out.After a UE who has only one radio link receives a RADIO LINK FAILURE INDICATIONmessage, it waits for recovery of the radio link's synchronization. The timer used in thiscase is specified by bits 24 to 31 of the RsvU32Para4(BSC6900,BSC6910) parameter inthe RNC MML command SET UALGORSVPARA.After a UE who has multiple radio links receives a RADIO LINK FAILURE INDICATIONmessage, it waits for recovery of the radio links' synchronization. The timer used in thiscase is specified by the value of the RlRstrTmr(BSC6900,BSC6910)parameter in the RNCMML command SET USTATETIMER.
l The best cell is under the SRNC and there is no CS signaling.
The UE transits to the common channel. Then, according to the traffic volume, it transits to adedicated channel to finish the call reestablishment. If an SRB resets during the D2P statetransition, the call reestablishment is performed in the same way as that performed during anSRB reset.
If there is data in the RLC buffer after the D2P state transition is successful, you can run theRNC MML command SET UALGORSVPARA with RESERVED_SWITCH_5_BIT13under RsvSwitch5(BSC6900,BSC6910) set to 0 and run the RNC MML command SETURRCTRLSWITCH with F2P_DATATRANS_OPTIMIZE_SWITCH underPROCESSSWITCH4(BSC6900,BSC6910) set to 1 to send paging messages to the UE again.
CELL_DCH-to-CELL_PCH reconfiguration and reestablishment is not triggered for thefollowing blacklisted UEs:
l TAC-based fast dormancy UEs for which FD_TAC_FORCE_D2F_SWITCH is set to 1l UEs for which PCH_DISABLED_SWITCH is set to 1l UEs for which SPECUSER_EFACH_DISABLED_SWITCH is set to 1l UEs for which SPECUSER_ERACH_DISABLED_SWITCH is set to 1l UEs that support the E-FACH or E-RACH and for which RESERVED_SWITCH_BIT1

4 SRB Reset
4.1 SRB Reset Detection
4.1.1 Detection PrincipleThe RNC sends a message in acknowledged mode (AM) to a UE. However, the RNC does notreceive an ACK message from the UE before the number of SRB RLC PDU retransmissionsreaches the value of the NoDiscardMaxDAT(BSC6900,BSC6910) parameter. If theAMRlcDiscardMode(BSC6900,BSC6910) parameter is set to NO_DISCARD, the RNCtriggers an SRB reset and sends the Reset PDU message to the UE to reestablish RLC entitieson both sides. Then one of the following occurs:
l If the call reestablishment function is not enabled, the RNC sends the Iu Release Requestmessage to the core network.
l If the call reestablishment function is enabled, call reestablishment is triggered.
4.1.2 Switches for Call Reestablishment Triggered by an SRB ResetTo enable the call reestablishment function triggered by an SRB reset, enable the service,process, and cause switches listed in Table 4-1.

5 TRB Reset
5.1 TRB Reset Detection
5.1.1 Detection PrincipleThe RNC sends an AM PDU to a UE initiating PS services in the CELL_DCH state. If the RNCdoes not receive a response from the UE, a TRB reset is triggered. Then one of the followingoccurs:
l If the call reestablishment function is not enabled, the RNC sends the Iu Release Requestmessage to the core network and the UE's PS services are interrupted.
l If the call reestablishment function is enabled, the RNC does not send the Iu ReleaseRequest message to the core network and call reestablishment is triggered. After the callreestablishment, the UE is still in the CELL_DCH state if theRL_REEST_PS_ON_FACH_SWITCH under the OptimizationSwitch3(BSC6900,BSC6910) parameter is turned off. If this switch is turned on, the UE moves tothe CELL_FACH state.

7.1 Air-Interface Process Overlap DetectionThe RNC sends a message to a UE, the RlRstrTmr(BSC6900,BSC6910) or T313(BSC6900,BSC6910) timer expires and an RL ut-of-synchronization problem occurs. For detailsabout whether to use the RlRstrTmr(BSC6900,BSC6910) or T313(BSC6900,BSC6910) timer,see 3.1 Uplink RL Out of Synchronization Detection.
The RNC initiates call reestablishment if the UE does not acknowledge the following messagesor the UE does not send the complete message to the RNC for the following message:
l Radio Bearer Setupl Radio Bearer Release (for a PS service)l Radio Bearer Reconfigurationl Physical Channel Reconfigurationl Security Mode Command
The signaling procedures are similar to those of air-interface process timeout. For details, see6.1 Air-Interface Process Timeout Detection.
To enable the call reestablishment function in this scenario, enable the service, process, andcause switches.

7.2 Call ReestablishmentExcept that the trigger cause is different, the process of call reestablishment triggered by air-interface process overlap is the same as that triggered by an RL out-of-synchronization problem.For details, see 3.2.2 Implementation.
When receiving an SRNS CONTEXT REQUEST message during a call reestablishmentprocedure, the RNC performs as follows:
l If RESERVED_SWITCH_10_BIT12 under RsvSwitch10(BSC6900,BSC6910) in theMML command SET UALGORSVPARA is set to 1, the RNC stops the callreestablishment process and sends an SRNS CONTEXT RESPONSE message to the CN.Then, the RNC waits for the IU RELEASE COMMAND message from the CN. Thesubsequent process is as follows:
– If RESERVED_SWITCH_10_BIT11 under RsvSwitch10(BSC6900,BSC6910) inthe MML command SET UALGORSVPARA is set to 1 and the RNC has not receivedthe IU RELEASE COMMAND message after the timer expires, the RNC sends an IURELEASE REQUEST message to the CN with the cause value "Normal Release" andperforms a normal release.
– If RESERVED_SWITCH_10_BIT11 under RsvSwitch10(BSC6900,BSC6910) inthe MML command SET UALGORSVPARA is set to 0 and the RNC has not receivedthe IU RELEASE COMMAND message after the timer expires, the RNC sends an IURELEASE REQUEST message to the CN with the cause value "TRELOCoverallexpiry" and performs an abnormal release.
l If RESERVED_SWITCH_10_BIT12 under RsvSwitch10(BSC6900,BSC6910) in theMML command SET UALGORSVPARA is set to 0, the RNC ignores the SRNSCONTEXT REQUEST message and continues to wait for the cell update message fromthe UE and finish the call reestablishment process.

9 Network Impact
9.1 System CapacityNo impact.
9.2 Network PerformanceWhen the call reestablishment function is enabled in scenarios with weak coverage or significantsignal fluctuation, calls will be reestablished for UEs with service interruptions or access failuresthat are caused by link failures or control/user plane faults. As a result, the call drop rate decreasesand the UE access success rate increases. The exact gains depend on the coverage of the livenetwork.
When a UE service is interrupted or the UE access fails, channel element (CE), code resources,and power resources are released for the UE. After call reestablishment succeeds, the releasedresources are re-occupied by the UE.
The call reestablishment function:
l Generally interrupts CS services for at least 4 seconds
l Does not affect network KPIs
l Affects CS user experience
l Slightly affects non-real-time PS user experience
When the call reestablishment function is enabled for the inter-RAT handover, the values of theKPIs IRATHO.AttOutCS and IRATHO.AttOutPSUTRAN will increase and the handoversuccess rate also increases because inter-RAT handovers are initiated again after callreestablishment is complete.
After the D2P reconfiguration and reestablishment algorithm is enabled, D2P state transitionattempts and successful D2P state transitions increase. Meanwhile, call drops or second RRCconnection setup attempts during CELL_DCH-to-CELL_PCH state transitions increase. Thatis, the values of the following counters increase:

10 Engineering Guidelines
10.1 When to Use Call ReestablishmentUse call reestablishment in temporary coverage holes and in tunnels, elevators, and buildingsthat cause significant radio signal fluctuation.
10.2 Required InformationBefore you enable this function, collect the following information:
l Causes of call drops or access failures and the number and proportion of times that UEsare involved in the processes performed over the air interface
The following formulas are used to calculate the percentage of RABs that are released dueto any of the five causes (RL out of synchronization, SRB reset, PS TRB reset, air interfaceprocess timeout, and air interface process overlapping) that may trigger call reestablishmentto all RABs that are abnormally released:
– For CS RAB releases, the following formula is used: (VS.RAB.AbnormRel.CS.RF/VS.RAB.AbnormRel.CS) x 100%, where the VS.RAB.AbnormRel.CS.RF counterindicates the number of CS RABs that are released due to the causes that may triggercall reestablishment and the VS.RAB.AbnormRel.CS counter indicates the total numberof abnormally released CS RABs.
– For PS RAB releases, the following formula is used: (VS.RAB.AbnormRel.PS.RF/VS.RAB.AbnormRel.PS) x 100%, where the VS.RAB.AbnormRel.PS.RF counterindicates the number of PS RABs that are released due to the causes that may triggercall reestablishment and the VS.RAB.AbnormRel.PS counter indicates the total numberof abnormally released PS RABs.
If the calculation result of either of the preceding formulas is greater than 30%, the CallReestablishment feature is recommended.
NOTE
To enable call reestablishment due to different trigger causes, processes, or service types, differentswitches need to be turned on. When the calculation result of the formula for CS or PS services isgreater than 30%, it is recommended that all corresponding switches for CS or PS services be turnedon.

l Whether RAB_SETUP_CNT_CORRECT_SWITCH under the ImprovementSwitch(BSC6900,BSC6910) parameter has been set to ON.
If it is not set to on, it is recommended that you run the following command to set it toON:SET URRCTRLSWITCH: ImprovementSwitch=RAB_SETUP_CNT_CORRECT_SWITCH-1;
After this switch is set to ON, the RNC counts call reestablishment attempts that fail in thefollowing scenarios:
– Scenario 1: In the RAB setup process, the RNC delivers a RADIO BEARER SETUPmessage to the UE but does not receive an ACK message from the UE. It initiates a callreestablishment process but the process fails.
– Scenario 2: In the RAB setup process, the RNC delivers a RADIO BEARER SETUPmessage to the UE but does not receive an ACK message from the UE. Instead, itreceives a cell update request with the cause value "radio link failure" or "RLCUnrecoverable error" and the cell update process fails.
– Scenario 3: In the RAB setup process, the RNC delivers a RADIO BEARER SETUPmessage to the UE and receives a cell update request with a cause value "cellreselection." However, the call update process fails.
l Value of the RAB assignment request response timer on the CN side, which must be greaterthan the value of RbSetupRspTmr(BSC6900,BSC6910) plus the timerCSRLReEstCellUpdateTmr(BSC6900,BSC6910) (for CS services) orPSRLReEstCellUpdateTmr(BSC6900,BSC6910) (for PS services).

Meaning: Whether the AM RLC entity discards theService Data Units (SDUs) that need to be sent and, ifso, the discard mode. This parameter is applicable onlyin the RLC AM mode. 1. If this parameter is set toTIMER_BASED_WITH_EXPLICIT_SIGNALLING,timer-based SDU discarding is triggered. Whenreceiving an SDU from upper layers, the TX end startsthe timer for discarding SDUs. If the timer expires, theTX end discards this SDU. At the same time, it sends aMove Receiving Window (MRW) command to the RXend, indicating the discard, to update the RX window.In this mode, "ExplicitTimerDiscard", "ExplicitTi-merMRW", and "ExplicitMaxMRW" need to be set. 2.If this parameter is set toDISCARD_AFTER_MAX_DAT_RETRANSMIS-SIONS, SDU discarding based on the maximumnumber of retransmissions is triggered. If the number oftransmissions of a PDU exceeds the number specifiedby "MaxDAT", the TX end discards the correspondingSDU. At the same time, it sends an MRW command tothe RX end, indicating this discard, to update the RXwindow. In this mode, "MaxDAT", "TimerMRW", and"MaxMRW" need to be set. 3. If this parameter is set toNO_DISCARD, the TX end does not discard any SDU.If the number of transmissions of a PDU exceeds apreset value, the AM RLC entity will be reset. In thismode, "NoDiscardMaxDAT" needs to be set. For detailsabout this parameter, see 3GPP TS 25.322. Some RLCSDUs may be discarded and so results in signalingpacket losses if this parameter is set toTIMER_BASED_WITH_EXPLICIT_SIGNALLINGor DISCARD_AFTER_MAX_DAT_RETRANSMIS-SIONS. Therefore, these values are not recommended.This parameter is an advanced parameter.
