Enhanced Fast Dormancy 2 Overview



2-1

2 Overview

Some intelligent UEs on a live network send a Signaling Connection Release Indication (SCRI) messageto the RNC after PS data transmission is complete. By sending the SCRI message, intelligent UEs

request for a transition to idle mode or the CELL_PCH or URA_PCH state to reduce batteryconsumption. Upon receiving the SCRI, the RNC can release the signaling connection and put the UEinto idle mode, or the RNC can maintain the signaling connection and put the UE to CELL_FACH orCELL_PCH/URA_PCH state. RSVDBIT1_BIT29of theRsvdPara1parameter in the SETURRCTRLSWITCH command controls the UE through CELL_FACH to CELL_PCH/URA_PCH ordirectly to CELL_PCH/URA_PCH. These procedures can reduce battery consumption, depending on theUE capability and feature activation on the RNC. By default, the RNC puts the UE into idle mode. A UEsetting up PS services in idle mode consumes more signaling resources than that in the CELL_PCH orURA_PCH state. If there are a large number of UEs transited between idle mode and CELL_DCH state,signaling storms may occur. The EFD feature puts UEs into the CELL_FACH or CELL_PCH state toreduce signaling resource consumption and eliminate signaling storms.

Huawei provides a comprehensive end-to-end solution based on network characteristics to respond to

network challenges. EFD is one component of the solution. This feature alone is not enough to eliminatesignaling storms caused by intelligent UEs. However, when applied with professional services, EFD canbe used to optimize the quality of service (QoS) for the entire network.

Consult Huawei engineers to receive the appropriate parameter settings for this feature along with other comprehensiveprofessional support. Do not configure the EFD parameters without Huawei professional technical support. Inappropriateparameter settings may lead to network failures.

The UEs on a live network can be divided into the following three types:

UEs that do not send SCRI messages because there is no PS data to be transmitted.

Pre fast dormancy UEs. This type of UE does not read the T323 information element (IE) carried in the

system information block type 1 (SIB1) message. After PS data transmission is complete, this type ofUE sends an SCRI message to the RNC, but the SCRI message does not carry the IE SignalingConnection Release Indication Cause. Both T323 and Signaling Connection Release Indication Causeare introduced in 3GPP Release 8.

R8 fast dormancy UEs. This type of UE reads the T323 IE carried in the SIB1 message and sends anSCRI message to the RNC after PS data transmission is complete. The SCRI message carries the IESignaling Connection Release Indication Cause that is set to "UE Requested PS Data session end."

The T323 IE carried in the SIB1 message controls the frequency at which the R8 fast dormancy UEssend SCRI messages with the IE Signaling Connection Release Indication Cause set to "UERequested PS Data session end". The T323 timer starts after an SCRI message is sent by the R8fast dormancy UEs, and the second SCRI message with the IE Signaling Connection Release

Indication Cause set to "UE Requested PS Data session end" can be sent only after the T323 timerexpires.

Among R8 UEs, some UEs neither send SCRI messages that include the Signaling ConnectionRelease Indication Cause IE nor read the T323 IE included in SIB1 messages. These UEs areregarded as pre fast dormancy UEs

The EFD feature applies only to the pre fast dormancy UEs and R8 fast dormancy UEs. Users canconfigure EFD to be enabled for only the pre fast dormancy UEs or R8 fast dormancy UEs.

When this feature is disabled, the RNC releases the signaling connection and puts the UE into idle modeafter receiving the SCRI message regardless the UE types.

When this feature is enabled, the RNC performs different processing based on the UE type:

For the pre fast dormancy UEs, the RNC checks for compatibility issues after receiving an SCRImessage. If there are no compatibility issues, the RNC puts the UE into the CELL_FACH or PCH state.If there is a compatibility issue, the RNC puts the UE into idle mode.

For the R8 fast dormancy UEs, the RNC puts the UE into the CELL_FACH or PCH state after receiving

an SCRI message.

Some pre fast dormancy UEs may have compatibility issues after moving to the CELL_FACH, CELL_PCH, or URA_PCHstate. As a result, new services cannot be initiated. This feature has been tested by using iPhones and no compatibilityissue occurred.

Enhanced Fast Dormancy 3 Technical Description



3-1

3 Technical Description

When there is no PS data to be transmitted, the intelligent UE sends the RNC an SCRI message torequest the UTRAN to release the signaling connection. This procedure saves power. In addition, the UE

periodically sends heartbeat messages to the core network, for example, to check for new mails on themail server. If the EFD feature is disabled, the RNC releases the signaling connection and puts the UEinto the idle state. In this case, sending heartbeat messages leads to the procedures for RRC connectionsetups, authentication, encryption, and RAB setups. These procedures increase the RNC signalingprocessing load.

EFD addresses this problem. With EFD, the RNC transits a UE to the CELL_FACH or PCH state insteadof idle mode upon receiving an SCRI message from the UE. In this case, when the UE periodically sendsheartbeat messages, the signaling procedure between the UE and RNC is simplified because the RRCconnection is maintained. As the number of signaling exchange messages decreases, significant CPUresources can be saved for the RNC, and the UE consumes about the same low amount of batterypower as a UE in idle mode.

This feature is controlled by FAST_DORMANCY_SWITCH ofthePROCESSSWITCHparameter in theSET URRCTRLSWITCHcommand.

Figure 3-1 shows the signaling processing procedures for pre fast dormancy UEs and R8 fast dormancyUEs before and after EFD is enabled.

Enhanced Fast Dormancy 4 Identifying Fast Dormancy UEs



4-1

4 Identifying Fast Dormancy UEs

The RNC identifies the pre fast dormancy UEs and R8 fast dormancy UEs using the followingmechanisms:

R8 fast dormancy: TheT323parameter that can be set in the SET UCONNMODETIMER command issent to the UE by the SIB1 message. The R8 fast dormancy UEs send an SCRI message with the IESignaling Connection Release Indication Cause set to "UE Requested PS Data session end" after PSdata transmission is complete. The RNC identifies the R8 fast dormancy UEs by reading the value ofIE Signaling Connection Release Indication Cause.

This mechanism is standardized by 3GPP Release 8. Some Release 6 and Release 7 smartphones,such as iPhones, have been enabled with the fast dormancy function defined in Release 8.

Pre fast dormancy: The RNC identifies the pre fast dormancy UEs using the Type Allocation Codes(TACs).

This mechanism, which is not standardized, is used for the early proprietary implementations of fastdormancy.

The international mobile equipment identity(IMEI), which consists of 14 decimal digits and one checkdigit, contains TAC and SNR. TAC indicates a particular type of device that has been approved by anational GSM/WCDMA approval body. SNR is the serial number identifying the UE. The structure of theIMEI, which is shown as follows, is specified in 3GPP TS 23.003.

TAC (8bit) SNR (6bit) Spare (1bit)

To identify pre fast dormancy UEs, FD_TAC_MATCH_SWITCH of thePROCESSSWITCHparameter onthe RNC side needs to be turned on. TheTACparameter has been set for the pre fast dormancy UEs bythe ADD UIMEITAC command afterFastDormancyis enabled. The RNC checks the TAC of the IMEI in

the IDENTITY REQUEST message. If the TAC is included in the EFD list, the UE can use EFD.

To enable normal UEs on a network to use the state transition mechanism of the EFD feature and putpre fast dormancy UEs that receive SCRI messages to idle mode, do as follows:

Turn off the FD_TAC_MATCH_SWITCH under thePROCESSSWITCHparameter.

Turn on the RNC_FD_SCRI_FORCE_REL_SWITCH under thePROCESSSWITCH2parameter in theSET URRCTRLSWITCH command.

After the preceding operations are performed, UEs complying with 3GPP Release 5 or later can useEFD and then you must remove all TACs with FastDormancy set to ON or OFF from the RNCconfiguration data.

Enhanced Fast Dormancy 5 State Transitions for Fast Dormancy UEs



5-1

5 State Transitions for Fast Dormancy UEs

When EFD is disabled, upon receiving an SCRI message from a UE, the RNC releases the UEs RRCconnection. The EFD switches are specified by the RNC-level subparameter

FAST_DORMANCY_SWITCHof the parameterPROCESSSWITCH.

When EFD is enabled, state transition procedures vary according to the UE type as follows:

For R8 fast dormancy UEs, pre fast dormancy UEs in the EFD list, and normal UEs:

The RNC puts R8 fast dormancy UEs to the idle mode to prevent compatibility issues when the RNCreceives an SCRI message where the Signaling Connection Release Indication Cause IE is set to"UE Requested PS Data session end" and then another SCRI message that does not include theSignaling Connection Release Indication Cause IE.

- The RNC puts UEs to the idle mode from the CELL_DCH or CELL_FACH state upon receiving anSCRI message where the Signaling Connection Release Indication Cause IE is excluded if theRNC_FD_SCRI_FORCE_REL_SWITCH under thePROCESSSWITCH2parameter in the SET

URRCTRLSWITCHcommand is turned on. When the RNC receives an SCRI message where theSignaling Connection Release Indication Cause IE is set to " UE Requested PS Data session end",the RNC puts these UEs to the CELL_FACH, CELL_PCH, or URA_PCH state.

If this switch is turned off, the RNC puts these UEs to the CELL_FACH, CELL_PCH, or URA_PCHstate upon receiving the SCRI message.

Note that the RSVDBIT1_BIT29(underRsvdPara1in SET URRCTRLSWITCH) andFD_TAC_FORCE_D2F_SWITCH(underPROCESSSWITCHin ADD UIMEITAC) jointly controlwhether these UEs are put to the CELL_FACH, CELL_PCH, or URA_PCH state from the CELL_DCHstate.

After PS data transmission is complete, If UE is in CELL_DCH, the PS inactivity timer(PsInactTmrForFstDrmDch)for EFD in CELL_DCH is started. If the PS inactivity timer for EFD inCELL_DCH expires, the RNC transfers the UE to CELL_FACH or CELL_PCH/URA_PCH.

After PS data transmission is complete, If UE is in CELL_FACH, the PS inactivity timer(PsInactTmrForFstDrmFach)for EFD in CELL_FACH is started. If the PS inactivity timer for EFD inCELL_FACH expires, the RNC transfers the UE to CELL_PCH/URA_PCH.RNC_DF_2_URA_PCH_SWITCH under thePROCESSSWITCHparameter in the SETURRCTRLSWITCHcommand controls whether the UE is transferred to the CELL_PCH or URA_PCHstate.

If UE is transferred to CELL_PCH/URA_PCH, the PS inactivity timer (PsInactTmrForPreFstDrm)isstarted. If the PS inactivity timer for EFD in CELL_PCH/URA_PCH expires, the RNC transfers the UEto IDLE. The value of this timer should be less than or equal to that ofT305,preventing the UE frombeing always in the CELL_PCH state and unable to enter the idle state.

If UE is in CELL_PCH/URA_PCH and has something to send and the condition for P2D/U2D is not

satisfied, the RNC instructs the UE to enter the CELL_FACH state. TAC-based P2D/U2D transitions. That is, when FD_P2D_SWITCHofPROCESSSWITCHin the

ADD UIMEITACcommand is turned on, a P2D/U2D transition starts if the UE's TAC is identical with theTAC added to the EFD list by running the ADD UIMEITACcommand and the UE experiences uplinkdata transmission or has a paging response in the PS domain.

For details about P2D/U2D transitions related to FACH congestion, see section 4.3 "FACHCongestion Control" inFlow Control Feature Parameter Description.

If UE is in CELL_FACH and send messages whose traffic volume is higher thanFastDormancyF2DHTvmThd,The RNC will transfer the UE from CELL_FACH to CELL_DCH.

The main factor for triggering the D2I transitions is FACH congestion. For details about statetransitions due to FACH congestion, see section 4.3 FACH Congestion ControlinFlow Control

For details about P2U/U2U/D2D/CPC/E-FACH and D2F/F2P based on 4B event state transitions, seeState Transition Feature Parameter Description.

For pre fast dormancy UEs not in EFD list:

If the RNC received the SCRI, the RNC transfers the UE to IDLE state.

The state transition for pre fast dormancy UEs not in EFD list is the same to ordinary UEs. For details,seeState Transition Feature Parameter Description.

For details about state transitions due to FACH congestion, see section 4.3 FACH CongestionControlinFlow Control Feature Parameter Description.

In the preceding descriptions, assume that single PS services are referred to. Upon receiving an SCRImessage from a UE processing CS+PS BE combined services, the RNC first releases the UE's PSsignaling connection. When the CS service is released, the RNC releases the UE's RRC connection.

Figure 5-1 shows the state transitions for R8 fast dormancy UEs and pre fast dormancy UEs in EFD list.

Table 5-1 State transitions for R8 fast dormancy UEs and pre fast dormancy UEs in EFD list

Type Description

D2P

D2U

D2F

F2P

F2U

D2P indicates a transition from CELL_DCH to CELL_PCH, F2P from CELL_FACH to

CELL_PCH, and D2F from CELL_DCH to CELL_FACH.The RNC starts the PS inactivity timer for fast dormancy when inactivity on PS data isdetected.

PsInactTmrForFstDrmDchspecifies the PS inactivity timer for CELL_DCH.

PsInactTmrForFstDrmFachspecifies the PS inactivity timer for CELL_FACH.

PsInactTmrForPreFstDrmspecifies the PS inactivity timer for CELL_PCH/URA_PCH.

If the UE is a fast dormancy UE and is not processing CS services, when the PS inactivitytimer for fast dormancy expires or the RNC receives an SCRI message from the UE, the UEchanges states as follows:

For a UE in the CELL_DCH state:

If RSVDBIT1_BIT29 ofRsvdPara1in the SET URRCTRLSWITCH command is turned offor FD_TAC_FORCE_D2F_SWITCHof thePROCESSSWITCHparameter in the ADDUIMEITACcommand is turned on, the RNC triggers a D2F transition.

If RSVDBIT1_BIT29 ofRsvdPara1in the SET URRCTRLSWITCH command is turned onand FD_TAC_FORCE_D2F_SWITCHofPROCESSSWITCHin the ADD UIMEITACcommand is turned off, the RNC triggers a D2P/D2U transition.

The D2F and F2P state transitions are recommended for the following reasons:

During an IOT test, some terminal issues occur. Occasionally, terminals fail to establish services after atransition from CELL_DCH to CELL_PCH/URA_PCH. This failure has a bad impact on user experience.

Compare with a state transition from CELL_DCH to CELL_FACH and then to CELL_PCH/URA_PCH,the state transition from CELL_DCH to CELL_PCH/URA_PCH does not improve the network

performance or user experience.

Some terminals send CELL UPDATE message to transfer data immediately after a state transition fromCELL_DCH to CELL_PCH/URA_PCH, which increases the signaling messages and leads to a heavyload on the Uu interface.

For a UE in the CELL_FACH state, the RNC trigger an F2P/F2U state transition.

The RNC_DF_2_URA_PCH_SWITCH under thePROCESSSWITCHparameter in theSET URRCTRLSWITCH command controls whether UEs are transferred to theCELL_PCH or URA_PCH state.

If this switch is turned on, the RNC initiates D2U or F2U state transitions.

If this switch is turned off, the RNC initiates D2P or F2P state transitions.

D2I/F2I D2I/F2I indicates a transition from CELL_DCH to idle.The RNC initiates D2I or F2I state transitions upon receiving an SCRI message where theSignaling Connection Release Indication Cause IE is excluded if theRNC_FD_SCRI_FORCE_REL_SWITCH under thePROCESSSWITCH2parameter in theSET URRCTRLSWITCHcommand is turned on.

D2I is mainly used for FACH congestion. For details about state transitions due to FACHcongestion, see section 4.3 FACH Congestion ControlinFlow Control Feature ParameterDescription.

Type Description

P2I/U2I P2I/U2I indicates a transition from CELL_PCH/URA_PCH to idle.

If the UE is in the CELL_PCH/URA_PCH state, when the PS inactivity timer for fast dormancy

(specified byPsInactTmrForPreFstDrm)expires, the RNC releases the UE's RRCconnection and then the UE enters idle mode.

P2D

U2D

P2D/U2D indicates a transition from CELL_PCH/URA_PCH to CELL_DCH.

TAC-based P2D/U2D transitions. That is, when FD_P2D_SWITCHofPROCESSSWITCHin the ADD UIMEITACcommand is turned on, a P2D/U2D transitionstarts if the UE's TAC is identical with the TAC added to the EFD list by running the ADDUIMEITACcommand and the UE experiences uplink data transmission or has a pagingresponse in the PS domain.

For details about P2D/U2D transitions related to FACH congestion, see section 4.3"FACH Congestion Control" inFlow Control Feature Parameter Description.

P2FU2F

P2F/U2F indicates a transition from CELL_PCH/URA_PCH to CELL_FACH.When the UE has something to send and the condition for P2D/U2D is not satisfied, the RNCinstructs the UE to enter the CELL_FACH state.

F2D F2D indicates a transition from CELL_FACH to CELL_DCH.

When a fast dormancy UE is in the CELL_FACH state, When the fast dormancy UE sendmessages whose traffic volume is higher thanFastDormancyF2DHTvmThd,The RNC willtransfer the UE from CELL_FACH to CELL_DCH. TheFastDormancyF2DHTvmThd is anew threshold of event 4a for fast dormancy UE, This threshold is set to bigger than trafficvolume of most heartbeat messages to prevent state transitions from being triggered by asmall-sized heartbeat messages.

Enhanced Fast Dormancy 6 Engineering Guidelines



6-1

6 Engineering Guidelines

6.1 When to Use Enhanced Fast Dormancy

The EFD feature is recommended for scenarios where the proportion of intelligent UEs is high, leadingto a high CPU load on SPU boards in the RNC and on baseband processing boards in the NodeB. Thisfeature reduces the Uu, Iu, and Iub signaling, uplink and downlink channel element (CE) consumption,and CPU load.

6.2 Feature Deployment

This feature cannot be configured using the CME.

6.2.1 Requirements

Dependencies on Hardware

This feature does not have any special requirements for hardware. Dependencies on Other Features

This feature does not depend on other features.

License

The licenses "Fast Dormancy Enhancement(per PS Active User)" on the RNC side have beenactivated. For details about the license items and how to activate the license, seeLicenseManagement Feature Parameter Description.

The license must be activated by performing the following operation first:

Run the BSC6900 MML command SET LICENSEto set Fast Dormancy Enhancement-per PS Active Userto an

appropriate value. Other Prerequisites

It is good practice to maintain load balancing among all frequencies in the network when using thisfeature, if the network is a service-layered network as follows and RSVDBIT1_BIT29of the Reservedparameter 1in the SET URRCTRLSWITCHcommand is set to 0, in order to reduce the call drops forUEs in the CELL_FACH state that support fast dormancy, Wait RB reconfiguration response timerand RL restoration timerin the SET USTATETIMERcommand need to be set to 11000and 15000respectively.

Frequency F1 carries R99 services.

Frequency F2 carries HSPA services.

F2 does not allow UEs in the idle, CELL_FACH, or CELL_PCH state to camp on.

6.2.2 Data Preparation

Before deploying the feature, consult Huawei engineers to obtain professional technical support.

6.2.3 Feature Activation (The UE supporting fast dormancy is aPre-Release 8 UE)

1. Run the BSC6900 MML command SET URRCTRLSWITCH to enable the feature Enhanced FastDormancy at the BSC6900-level. In this step, select the FAST_DORMANCY_SWITCH under thePROCESSSWITCH.

2. Run the BSC6900 MML command SET URRCTRLSWITCH to select the

RNC_PS_QUERY_UE_IMEI_SWITCH under thePROCESSSWITCH2.

3. Run the BSC6900 MML command SET URRCTRLSWITCH to enable cell update during CS servicesetup. In this step, deselect the RSVDBIT1_BIT21 check box under the parameter ReservedParameter 1.

After this feature is enabled, the number of CELL_DCH-to-CELL_FACH (D2F) procedures performed increases. If a CSservice is initiated after the UE performs a D2F procedure, a cell update procedure may be initiated during the CS servicesetup. The switch RSVDBIT1_BIT21specifies whether to allow cell update during CS service setup.

When the switch is turned off and a UE sends the RNC a CELL UPDATE message containing a cause value of cellreselection, the RNC preferentially processes the CELL UPDATE message and stops the AMR service setup even if theUE is setting up an AMR service and performing a D2F state transition.

When this switch is turned on, the RNC preferentially processes the CELL UPDATE message and continues with the AMRservice setup after the cell update procedure is completed

4. Run the BSC6900 MML command SET URRCTRLSWITCH to enable the state transition fromCELL_PCH or URA_PCHtoCELL_DCHtriggered by FACH congestion. In this step, deselect theRSVDBIT1_BIT20check box under the parameter Reserved Parameter 1.

5. Run the BSC6900 MML command SET URRCTRLSWITCH to disable the state transition from

CELL_DCH to CELL_PCH. In this step, deselect the RSVDBIT1_BIT29 check box under theparameter Reserved Parameter 1.

The switch RSVDBIT1_BIT29specifies whether to allow the state transition from CELL_DCH to CELL_PCH. When thisswitch is turned on, the state transition from CELL_DCH to CELL_PCH is allowed. When this switch is turned off, the statetransition from CELL_DCH to CELL_PCH is not allowed.

After this feature is enabled, the FACH will carry a large amount of data, which may lead to FACH congestion. Therefore, itis recommended that a new SCCPCH be added.

For details about how to handle FACH congestion in other methods, see section "FACH Congestion Control" in the FlowControl in the RAN Feature Documentation.

6. Run the BSC6900 MML command SET UPSINACTTIMER to set the value of the CELL_DCH,CELL_FACH, and CELL_PCH inactivity timer respectively.

The recommended value of theFAST DORMANCY USER T1 in CELL_DCH is 5seconds.

The recommended value of theFAST DORMANCY USER T1in CELL_FACH is 5seconds.

The recommended value of the FAST DORMANCY USER T1in CELL_PCH is 1800 seconds.

When activating the EFD feature, use the preceding recommended values for the FAST DORMANCY USER T1 inCELL_DCH, FAST DORMANCY USER T1 in CELL_FACH, and FAST DORMANCY USER T1 in CELL_PCHparameters

7. Run the BSC6900 MML command SET UUESTATETRANS. In this step, set Fast Dormancy UserFACH/E_FACH2DCH/HSPA 4A Threshold toD1024.

When activating the EFD feature, use the preceding recommended value for the Fast Dormancy UserFACH/E_FACH2DCH/HSPA 4A Thresholdparameter.

10. Run the RNC MML command ADD TRMFACTORto add activation factor table. In this step, set theFactor table indexparameter and the related activation factors for each service. It is recommendedthat all the activation factors be set to 10.

After this feature is enabled, the number of UEs in the CELL_PCH or URA_PCH state increases sharply. UEs in theCELL_PCH or URA_PCH state consume a large number of Iu-PS bandwidth resources although they do not transmit anydata.

Adjusting the Iu-PS activity factor can prevent PS service admission failures due to the increase in the number of UEs inthe CELL_PCH or URA_PCH state.

The value of the Factor table indexparameter in the ADD TRMFACTOR command cannot conflict withthe indexes of other activation factor tables

The Iu-PS activity factor of all services must be set to an appropriate value. Otherwise, a large number ofPS service setups fail, and the CPU usage of the SPU boards increases sharply.

6.2.4 Feature Activation (The UE supporting fast dormancy is aRelease 8 or later Release UE)

1. Run the BSC6900 MML command SET URRCTRLSWITCH to enable the feature Enhanced FastDormancy at the BSC6900-level. In this step, select the FAST_DORMANCY_SWITCH under thePROCESSSWITCH.

2. Run the BSC6900 MML command SET UCONNMODETIMERto set the value of the Timer 323.

If the UE supporting fast dormancy is a Release 8 or later Release UE, you need to set timer 323after enabling fastdormancy. When the network supports the CELL_PCHorURA_PCH, it is good practice to set timer 323to 120s. Whenthe network does not support CELL_PCHor URA_PCH, it is good practice to set timer 323to 10s.

3. Run the BSC6900 MML command SET URRCTRLSWITCHto enable cell update during CS servicesetup. In this step, deselect the RSVDBIT1_BIT21 check box under the parameter ReservedParameter 1.

After this feature is enabled, the number of CELL_DCH-to-CELL_FACH (D2F) procedures performed increases. If a CSservice is initiated after the UE performs a D2F procedure, a cell update procedure may be initiated during the CS service

setup. The switch RSVDBIT1_BIT21specifies whether to allow cell update during CS service setup.

When the switch is turned off and a UE sends the RNC a CELL UPDATE message containing a cause value of cellreselection, the RNC preferentially processes the CELL UPDATE message and stops the AMR service setup even if theUE is setting up an AMR service and performing a D2F state transition.

When this switch is turned on, the RNC preferentially processes the CELL UPDATE message and continues with the AMRservice setup after the cell update procedure is completed.

4. Run the BSC6900 MML command SET URRCTRLSWITCH to enable the state transition fromCELL_PCHorURA_PCH to CELL_DCHtriggered by FACH congestion. In this step, deselect theRSVDBIT1_BIT20check box under the parameter Reserved Parameter 1.

5. Run the BSC6900 MML command SET URRCTRLSWITCH to disable the state transition fromCELL_DCH to CELL_PCH. In this step, deselect the RSVDBIT1_BIT29 check box under theparameter Reserved Parameter 1.

The switch RSVDBIT1_BIT29specifies whether to allow the state transition from CELL_DCH to CELL_PCH. When thisswitch is turned on, the state transition from CELL_DCH to CELL_PCH is allowed. When this switch is turned off, the statetransition from CELL_DCH to CELL_PCH is not allowed.

After this feature is enabled, the FACH will carry a large amount of data, which may lead to FACH congestion. Therefore, itis recommended that a new SCCPCH be added.

For details about how to handle FACH congestion in other methods, see section "FACH Congestion Control" in the FlowControl in the RAN Feature Documentation.

6. Run the BSC6900 MML command SET UPSINACTTIMER to set the value of the CELL_DCH,CELL_FACH, andCELL_PCHinactivity timer respectively.

The recommended value of the FAST DORMANCY USER T1 in CELL_DCH is 5 seconds.

The recommended value of the FAST DORMANCY USER T1 in CELL_FACH is 5 seconds.

The recommended value of the FAST DORMANCY USER T1 in CELL_PCH is 1800 seconds.

When activating the EFD feature, use the preceding recommended values for the FAST

DORMANCY USER T1in CELL_DCH, FAST DORMANCY USER T1 in CELL_FACH, and FASTDORMANCY USER T1 in CELL_PCH parameters.

7. Run the BSC6900 MML command SET UUESTATETRANS. In this step, set Fast Dormancy UserFACH/E_FACH2DCH/HSPA 4A Threshold toD1024.

When activating the EFD feature, use the preceding recommended value for the Fast DormancyUserFACH/E_FACH2DCH/HSPA 4A Thresholdparameter.

8. Run the BSC6900 MML command SET URRCTRLSWITCH to enable the Type Allocation Code(TAC) match function. In this step, select the FD_TAC_MATCH_SWITCH under thePROCESSSWITCH.

9. Run the RNC MML command ADD TRMFACTORto add an activation factor table. In this step, setthe Factor table index parameter and the related activation factors for each service. It isrecommended that all these factors be set to 10%.

10. Run the RNC MML command MOD ADJMAPto replace the Iu-PS activation factor table with the oneadded in step 9. If the related activation factors are already set to 10%, skip this step.


Adjusting the Iu-PS activity factor can prevent PS service admission failures due to the increase in the number of UEs inthe CELL_PCH or URA_PCH state.

The value of the Factor table indexparameter in the ADD TRMFACTOR command cannot conflict with the indexes of

other activation factor tables.

The Iu-PS activity factor of all services must be set to an appropriate value. Otherwise, a large number ofPS service setups fail, and the CPU usage of the SPU boards increases sharply.

6.2.5 Feature Activation (The UE supporting fast dormancycomplies with 3GPP Release 5 or later)

1. Run the RNC MML command SET URRCTRLSWITCH and select the

FAST_DORMANCY_SWITCH check box under the PROCESSSWITCHparameter to activate theEFD feature at the RNC level.

2. Run the RNC MML command SET UCONNMODETIMER with the Timer 323parameter set to anappropriate value.

When the UE supporting fast dormancy complies with 3GPP Release 8 or later, set the Timer 323parameter to anappropriate value after activating the EFD feature at the RNC level. If the network supports the CELL_PCH or URA_PCHstate, the recommended value for this parameter is 120. If the network does not support the CELL_PCH or URA_PCHstate, the recommended value is 10.

3. Run the RNC MML command SET URRCTRLSWITCHto enable cell update during CS service setup.In this step, clear the RSVDBIT1_BIT21check box under the Reserved parameter 1parameter.

For details about cell update during CS service setup, see "Enhanced Combined Services Feature ParameterDescription".

4. Run the RNC MML command SET URRCTRLSWITCH to enable the state transition fromCELL_PCH or URA_PCH to CELL_DCH triggered by FACH congestion. In this step, clear theRSVDBIT1_BIT20check box under the Reserved parameter 1parameter.

5. Run the RNC MML command SET URRCTRLSWITCH to disable the state transition fromCELL_DCH to CELL_PCH. In this step, clear the RSVDBIT1_BIT29 check box under the Reservedparameter 1parameter.

The RSVDBIT1_BIT29switch controls whether to allow UEs to perform the state transition from CELL_DCH toCELL_PCH. When the RSVDBIT1_BIT29check box is selected, UEs can perform the state transition from CELL_DCH toCELL_PCH. When the RSVDBIT1_BIT29check box is cleared, UEs cannot perform the state transition from CELL_DCHto CELL_PCH.

After this feature is enabled, the FACH will carry a large amount of data, which may lead to FACH congestion. Therefore, itis recommended that a new S-CCPCH be added. For details about how to solve FACH congestion, see the "FACHCongestion Control" section inFlow Control Feature Parameter Description.

When the switch isturned off and theBSC6900-level D2Fswitch is turned on,state transition from

CELL_DCH toCELL_FACH is forciblyperformed on the UEwith the correspondingTAC and supporting fastdormancy.

10)CR2284R1_SWITCH.

In section 8.6.6.28 ofTS25.331 of R5Before2006, it describesthat the HFN should addone when UE isciphering in the situation

of Timing re-initializedhard handover, whilenot specified in RBSETUP process in thesection of 8.6.4.3. so itis not clear whether toadd or not in RB SETUPin DRD scenarios.CR2284R1 clarify thatHFN should add one inRB SETUP process withTiming re-initialized

hard handover. when itis checked ,RNCaccepts this CR2284R1;when it is notchecked ,RNC does notaccept this CR2284R1.
