2 Overview

Some intelligent UEs on a live network send a Signaling Connection Release Indication (SCRI)message to 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 toreduce battery consumption. Upon receiving the SCRI, the RNC can release the signalingconnection and put the UE into idle mode, or the RNC can maintain the signaling connectionand put the UE to CELL_FACH or CELL_PCH/URA_PCH state. By default, the RNC puts theUE into idle mode. A UE setting up PS services in idle mode consumes more signaling resourcesthan that in the CELL_PCH or URA_PCH state. If there are a large number of UEs transitedbetween idle mode and CELL_DCH state, signaling storms may occur. The EFD feature putsUEs into the CELL_FACH or CELL_PCH state to reduce signaling resource consumption andeliminate signaling storms.

Huawei provides a comprehensive end-to-end solution based on network characteristics torespond to network challenges. EFD is one component of the solution. This feature alone is notenough to eliminate signaling storms caused by intelligent UEs. However, when applied withprofessional services, EFD can be used to optimize the quality of service (QoS) for the entirenetwork.

NOTE

Consult Huawei engineers to receive the appropriate parameter settings for this feature along with othercomprehensive professional support. Do not configure the EFD parameters without Huawei professionaltechnical support. Inappropriate parameter settings may lead to network failures.

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

l Normal UEs. This type of UEs does not send SCRI messages after completing datatransmission.

l 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 transmissionis complete, this type of UE sends an SCRI message to the RNC, but the SCRI messagedoes not carry the IE Signaling Connection Release Indication Cause. Both T323 andSignaling Connection Release Indication Cause are introduced in 3GPP Release 8.

l Fast dormancy UEs. This type of UEs confirms with 3GPP R8. The UEs read the T323 IEcarried in the SIB1 message and send an SCRI message to the RNC after PS datatransmission is complete. The SCRI message carries the IE Signaling Connection ReleaseIndication Cause that is set to "UE Requested PS Data session end." However though some

WCDMA RANEnhanced Fast Dormancy Feature Parameter Description 2 Overview


4

UEs are R8 they do not send SCRI with cause reason and do not read the T323, that meansthey have behavior as pre fast dormancy UEs.Among R8 UEs, some UEs neither send SCRI messages that include the SignalingConnection Release Indication Cause IE nor read the T323 IE included in SIB1 messages.These UEs are regarded as pre fast dormancy UEs.The T323 IE carried in the SIB1 message controls the frequency at which the fast dormancyUEs send SCRI messages with the IE Signaling Connection Release Indication Cause setto "UE Requested PS Data session end". The T323 timer starts after an SCRI message issent by the fast dormancy UEs, and the second SCRI message with the IE SignalingConnection Release Indication Cause set to "UE Requested PS Data session end" can besent only after the T323 timer expires.

For details about SCRI messages, see section 8.1.14 "Signalling connection release indicationprocedure" in 3GPP TS 25.331 V10.7.0.

When the EFD is disabled, the RNC releases the signaling connection and puts the UE into idlemode after receiving the SCRI message regardless the UE types. When the EFD is enabled, theRNC performs different processing based on the UE type:

l For the pre fast dormancy UEs, the RNC checks for compatibility issues after receiving anSCRI message. If there are no compatibility issues, the RNC puts the UE into theCELL_FACH or PCH state. If there is a compatibility issue, the RNC puts the UE into idlemode.

l For the fast dormancy UEs, the RNC puts the UE into the CELL_FACH or PCH state afterreceiving an SCRI message.

NOTE

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

3 Technical Description

When there is no PS data to be transmitted, the intelligent UE sends the RNC an SCRI messageto request the UTRAN to release the signaling connection. This procedure saves power. Inaddition, the UE periodically sends heartbeat messages to the core network, for example, tocheck for new mails on the mail server. If the EFD feature is disabled, the RNC releases thesignaling connection and puts the UE into the idle state. In this case, sending heartbeat messagesleads to the procedures for RRC connection setups, authentication, encryption, and RAB setups.These procedures increase the RNC signaling processing load.

EFD addresses this problem. With EFD, the RNC transits a UE to the CELL_FACH or PCHstate instead of idle mode upon receiving an SCRI message from the UE. In this case, when theUE periodically sends heartbeat messages, the signaling procedure between the UE and RNC issimplified because the RRC connection is maintained. As the number of signaling exchangemessages decreases, significant CPU resources can be saved for the RNC, and the UE consumesabout the same low amount of battery power as a UE in idle mode.

This feature is controlled by FAST_DORMANCY_SWITCH of the PROCESSSWITCH(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCH command.

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

4 Identifying Fast Dormancy UEs

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

l Fast Dormancy: The T323(BSC6900,BSC6910) parameter that can be set in the SETUCONNMODETIMER command is sent to the UE by the SIB1 message. The fastdormancy UEs send an SCRI message with the IE Signaling Connection Release IndicationCause set to "UE Requested PS Data session end" after PS data transmission is complete.The RNC identifies the fast dormancy UEs by reading the value of IE Signaling ConnectionRelease Indication Cause.

NOTE

Once a UE is identified as an R8 fast dormancy UE, the RNC keeps this property unchanged beforethe UE's RRC connection is released.

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

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

This mechanism, which is not standardized, is used for the early proprietaryimplementations of fast dormancy.

The international mobile equipment identity (IMEI), which consists of 14 decimal digitsand one check digit, contains TAC and SNR. TAC indicates a particular type of device thathas been approved by a national GSM/WCDMA approval body. SNR is the serial numberidentifying the UE. The structure of the IMEI, which is shown as follows, is specified insection 6.2.1 "Composition of IMEI" of 3GPP TS 23.003.

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

When the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH(BSC6900,BSC6910) parameter is turned on, the RNC determines whether pre fast dormancyUEs can use EFD based on their TACs. Specifically, upon receiving an IDENTITY REQUESTmessage from a pre fast dormancy UE, the RNC checks whether the TAC in the IMEI IE of themessage is on the EFD list.

l If so, the UE can use EFD.

WCDMA RANEnhanced Fast Dormancy Feature Parameter Description 4 Identifying Fast Dormancy UEs


8

l If not, the UE cannot use EFD. To enable the UE to use EFD, run the ADD UIMEITACcommand to set the TAC(BSC6900,BSC6910) parameter to the UE's TAC, turn on theFastDormancy(BSC6900,BSC6910) switch, and set the TAC_FUNC(BSC6900,BSC6910) parameter to Fast_Dormancy.

To enable UEs complying with 3GPP Release 5 or later to use EFD, perform the followingoperations:

l Turn off the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH(BSC6900,BSC6910) parameter. This includes these UEs' TACs in the EFD list so thatthey can use EFD.

l Turn on the RNC_FD_SCRI_FORCE_REL_SWITCH under the PROCESSSWITCH2(BSC6900,BSC6910) parameter. This enables the RNC to put pre fast dormancy UEs toidle mode upon receiving an SCRI message that excludes the "Signaling ConnectionRelease Indication Cause" IE from them.

After you perform these two operations, you must clear the EFD list as follows:

l Run the LST UIMEITAC command and records TACs whose TAC_FUNC(BSC6900,BSC6910) is set to Fast_Dormancy.

l For each of these TACs, run the RMV UIMEITAC command, specify the TAC(BSC6900,BSC6910) parameter, and set the TAC_FUNC(BSC6900,BSC6910) parameterto Fast_Dormancy.

5 State Transitions for Fast Dormancy UEs

When EFD is disabled, upon receiving an SCRI message from a UE, the RNC releases the UE'sPS signaling connection. The EFD switches are specified by the RNC-level subparameterFAST_DORMANCY_SWITCH of the parameter PROCESSSWITCH(BSC6900,BSC6910).

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

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

– The RNC puts fast dormancy UEs to the idle mode to prevent compatibility issues whenthe RNC receives an SCRI message where the Signaling Connection Release IndicationCause IE is set to "UE Requested PS Data session end" and then another SCRI messagethat does not include the Signaling Connection Release Indication Cause IE.

– The RNC puts UEs to the idle mode from the CELL_DCH or CELL_FACH state uponreceiving an SCRI message where the Signaling Connection Release Indication CauseIE is excluded if the RNC_FD_SCRI_FORCE_REL_SWITCH under thePROCESSSWITCH2(BSC6900,BSC6910) parameter in the SETURRCTRLSWITCH command is turned on. When the RNC receives an SCRImessage where the Signaling Connection Release Indication Cause IE is set to " UERequested 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_PCH state upon receiving the SCRI message. Note that theRNC_EFD_D2F_SWITCH (under OptimizationSwitch(BSC6900,BSC6910) in SETURRCTRLSWITCH) and FD_TAC_FORCE_D2F_SWITCH (underPROCESSSWITCH(BSC6900,BSC6910) in ADD UIMEITAC) jointly controlwhether these UEs are put to the CELL_FACH, CELL_PCH, or URA_PCH state fromthe CELL_DCH state.

– After PS data transmission is complete, If UE is in CELL_DCH, the PS inactivity timerPsInactTmrForFstDrmDch(BSC6900,BSC6910) for EFD in CELL_DCH is started.If the PS inactivity timer for EFD in CELL_DCH expires, the RNC transfers the UE toCELL_FACH or CELL_PCH/URA_PCH.

– After PS data transmission is complete, If UE is in CELL_FACH, the PS inactivitytimer PsInactTmrForFstDrmFach(BSC6900,BSC6910) for EFD in CELL_FACH isstarted. If the PS inactivity timer for EFD in CELL_FACH expires, the RNC transfersthe UE to CELL_PCH/URA_PCH.

10

The RNC_DF_2_URA_PCH_SWITCH under the PROCESSSWITCH(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCH command controlswhether the UE is transferred to the CELL_PCH or URA_PCH state.

– If UE is transferred to CELL_PCH/URA_PCH, the PS inactivity timerPsInactTmrForPreFstDrm(BSC6900,BSC6910) is started. If the PS inactivity timerfor EFD in CELL_PCH/URA_PCH expires, the RNC transfers the UE to IDLE. Thevalue of this timer should be less than or equal to that of T305(BSC6900,BSC6910),preventing the UE from being always in the CELL_PCH state and unable to enter theidle state.

– If UE is in CELL_PCH/URA_PCH and has something to send and the condition forP2D/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_SWITCH ofPROCESSSWITCH(BSC6900,BSC6910) in the ADD UIMEITAC command isturned on, a P2D/U2D transition starts if the UE's TAC is identical with the TAC addedto the EFD list by running the ADD UIMEITAC command and the UE experiencesuplink data transmission or has a paging response in the PS domain.

– For details about P2D/U2D transitions related to FACH congestion, see "FACHCongestion Control" in Flow Control Feature Parameter Description.

– If UE is in CELL_FACH and send messages whose traffic volume is higher thanFastDormancyF2DHTvmThd(BSC6900,BSC6910), The RNC will transfer the UEfrom CELL_FACH to CELL_DCH.

– The main factor for triggering the D2I transitions is FACH congestion. For details aboutstate transitions due to FACH congestion, see section "FACH Congestion Control" inFlow Control Feature Parameter Description.

– For details about P2U/U2U/D2D/CPC/E-FACH and D2F/F2P based on 4B event statetransitions, see State Transition Feature Parameter Description.

l 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 ordinaryUEs. For details, see State Transition Feature Parameter Description.

– For details about state transitions due to FACH congestion, see section "FACHCongestion Control" in Flow Control Feature Parameter Description.

NOTE

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 PS signalingconnection. When the CS service is released, the RNC releases the UE's RRC connection.

Figure 5-1 shows the state transitions for EFD.

Type Description

D2PD2UD2FF2PF2U

D2P/D2U indicates a transition from CELL_DCH to CELL_PCH/URA_PCH,F2P/F2U from CELL_FACH to CELL_PCH/URA_PCH, and D2F fromCELL_DCH to CELL_FACH.The RNC starts the PS inactivity timer for fast dormancy when inactivity on PSdata is detected.l PsInactTmrForFstDrmDch(BSC6900,BSC6910) specifies the PS inactivity

timer for CELL_DCH.l PsInactTmrForFstDrmFach(BSC6900,BSC6910) specifies the PS

inactivity timer for CELL_FACH.l PsInactTmrForPreFstDrm(BSC6900,BSC6910) specifies the PS inactivity

timer for CELL_PCH/URA_PCH.If the UE is a fast dormancy UE and is not processing CS services, when thePS inactivity timer for fast dormancy expires or the RNC receives an SCRImessage from the UE, the UE changes states as follows:

For a UE in the CELL_DCH state:l If RNC_EFD_D2F_SWITCH of the OptimizationSwitch

(BSC6900,BSC6910) in the SET URRCTRLSWITCH command is turnedon or FD_TAC_FORCE_D2F_SWITCH of the PROCESSSWITCH(BSC6900,BSC6910) parameter in the ADD UIMEITAC command is turnedon, the RNC triggers a D2F transition.

l If RNC_EFD_D2F_SWITCH of the OptimizationSwitch(BSC6900,BSC6910) in the SET URRCTRLSWITCH command is turnedoff and FD_TAC_FORCE_D2F_SWITCH of PROCESSSWITCH(BSC6900,BSC6910) in the ADD UIMEITAC command is turned off, theRNC triggers a D2P/D2U transition.

For a UE in the CELL_FACH state, the RNC trigger an F2P/F2U state transition.l The RNC_DF_2_URA_PCH_SWITCH under the PROCESSSWITCH

(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCH commandcontrols whether UEs are transferred to the CELL_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.

NOTEThe D2F and F2P/F2U state transitions are recommended for the following reasons:

l During an IOT test, some terminal issues occur. Occasionally, terminals fail to establishservices after a transition from CELL_DCH to CELL_PCH/URA_PCH. This failure hasa bad impact on user experience.

l Compare with a state transition from CELL_DCH to CELL_FACH and then toCELL_PCH/URA_PCH, the state transition from CELL_DCH to CELL_PCH/URA_PCH does not improve the network performance or user experience.

l Some terminals send CELL UPDATE message to transfer data immediately after a statetransition from CELL_DCH to CELL_PCH/URA_PCH, which increases the signalingmessages and leads to a heavy load on the Uu interface.

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

Type Description

D2I//F2I D2I/F2I indicates a transition from CELL_DCH/CELL_FACH to idle.The RNC initiates D2I or F2I state transitions upon receiving an SCRI messagewhere the Signaling Connection Release Indication Cause IE is excluded if theRNC_FD_SCRI_FORCE_REL_SWITCH under the PROCESSSWITCH2(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCH command isturned on.D2I is also used for FACH congestion. For details about state transitions due toFACH congestion, see section "FACH Congestion Control" in Flow ControlFeature Parameter 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 forfast dormancy (specified by PsInactTmrForPreFstDrm(BSC6900,BSC6910))expires, the RNC releases the UE's RRC connection and then the UE enters idlemode.

P2DU2D

P2D/U2D indicates a transition from CELL_PCH/URA_PCH to CELL_DCH.l TAC-based P2D/U2D transitions. That is, when FD_P2D_SWITCH of

PROCESSSWITCH(BSC6900,BSC6910) in the ADD UIMEITACcommand is turned on, a P2D/U2D transition starts if the UE's TAC is identicalwith the TAC added to the EFD list by running the ADD UIMEITACcommand and the UE experiences uplink data transmission or has a pagingresponse in the PS domain.

l For details about P2D/U2D transitions related to FACH congestion, see section"FACH Congestion Control" in Flow Control Feature ParameterDescription.

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 notsatisfied, the RNC instructs 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 dormancyUE send messages whose traffic volume is higher thanFastDormancyF2DHTvmThd(BSC6900,BSC6910), The RNC will transfer theUE from CELL_FACH to CELL_DCH. The FastDormancyF2DHTvmThd(BSC6900,BSC6910) is a new threshold of event 4a for fast dormancy UE, Thisthreshold is set to bigger than traffic volume of most heartbeat messages to preventstate transitions from being triggered by a small-sized heartbeat messages.

6 Engineering Guidelines

6.1 When to Use Enhanced Fast DormancyThe EFD feature is recommended for scenarios where the proportion of intelligent UEs is high,leading to a high CPU load on control-plane board in the RNC and on baseband processingboards in the NodeB. This feature reduces the Uu, Iu, and Iub signaling, uplink and downlinkchannel element (CE) consumption, and CPU load.

NOTE

For the BSC6900, a signaling processing unit is the SPUa or SPUb board.

For the BSC6910, a signaling processing unit is the EGPUa board.

NOTE

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

Run the RNC MML command SET LICENSE to set Fast Dormancy Enhancement-per PS ActiveUser to an appropriate value.

l Other PrerequisitesIt is good practice to maintain load balancing among all frequencies in the network whenusing this feature, if the network is a service-layered network as follows andRNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) of the Optimization Switchin the SET URRCTRLSWITCH command is set to 1, in order to reduce the call dropsfor UEs in the CELL_FACH state that support fast dormancy, Wait RB reconfigurationresponse timer and RL restoration timer in the SET USTATETIMER command needto be set to 11000 and 15000 respectively.

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

6.2.3 Feature Activation for Pre-Release 8 UEThis feature cannot be configured using the CME.

Using MML Commands

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

Step 2 Run the RNC MML command SET URRCTRLSWITCH to select theRNC_PS_QUERY_UE_IMEI_SWITCH under the PROCESSSWITCH2.

Step 3 Run the RNC MML command SET URRCTRLSWITCH to enable cell update during CSservice setup. In this step, select the AMR_F2D_OVERLAP_CELLUPT_SWITCH(AMR_F2D_OVERLAP_CELLUPT_SWITCH) check box under the parameterOptimization Switch.



16

NOTE

After this feature is enabled, the number of CELL_DCH-to-CELL_FACH (D2F) procedures performedincreases. If a CS service is initiated after the UE performs a D2F procedure, a cell update procedure maybe initiated during the CS service setup. The switch AMR_F2D_OVERLAP_CELLUPT_SWITCH(AMR_F2D_OVERLAP_CELLUPT_SWITCH) specifies whether to allow cell update during CSservice setup.

When the switch is turned off and a UE sends the RNC a CELL UPDATE message containing a causevalue of cell reselection, the RNC preferentially processes the CELL UPDATE message and stops theAMR service setup even if the UE 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 continueswith the AMR service setup after the cell update procedure is completed

Step 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, selectthe P2D_SWITCH(P2D_SWITCH) check box under the parameter Optimization Switch.

Step 5 Run the RNC MML command SET URRCTRLSWITCH to enable the state transition fromCELL_DCH to CELL_PCH. In this step, deselect the RNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) check box under the parameter Optimization Switch.

NOTE

The switch RNC_EFD_D2F_SWITCH(RNC_EFD_D2F_SWITCH) specifies whether to allow thestate transition from CELL_DCH to CELL_FACH. When this switch is turned on, the state transition fromCELL_DCH to CELL_FACH is allowed. When this switch is turned off, the state transition fromCELL_DCH to CELL_PCH is allowed.

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

For details about how to handle FACH congestion in other methods, see section "FACH CongestionControl" in the Flow Control Feature Parameter Description.

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

l The recommended value of the FAST DORMANCY USER T1 in CELL_DCH is 2 seconds.

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

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

NOTE

When activating the EFD feature, use the preceding recommended values for the FAST DORMANCYUSER T1 in CELL_DCH, FAST DORMANCY USER T1 in CELL_FACH, and FAST DORMANCYUSER T1 in CELL_PCH parameters.

Step 7 Run the RNC MML command SET UUESTATETRANS. In this step, set Fast Dormancy UserFACH/E_FACH2DCH/HSPA 4A Threshold to D512.

NOTE

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

Step 9 Run the RNC MML commandADD UIMEITAC to set the value of the TAC to add the IMEITACs of smart UEs to the EFD list, and set the Fast Dormancy Switch to ON.

Step 10 Run the RNC MML command ADD TRMFACTOR to add activation factor table. In this step,set the factor table index and the activation factors for each service. It is recommended that allthe activation factors be set to 10.

Step 11 Run the RNC MML command MOD ADJMAP to set the Iu-PS activation factor table to theconfigured in the previous step. If the activation factors have been set to 10%, you don't have todo this step.

----End

NOTE

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

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

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

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

After this feature is enabled, the number of CELL_DCH-to-CELL_FACH (D2F) procedures performedincreases. If a CS service is initiated after the UE performs a D2F procedure, a cell update procedure maybe initiated during the CS service setup. The switch AMR_F2D_OVERLAP_CELLUPT_SWITCH(AMR_F2D_OVERLAP_CELLUPT_SWITCH) specifies whether to allow cell update during CSservice setup.

When the switch is turned off and a UE sends the RNC a CELL UPDATE message containing a causevalue of cell reselection, the RNC preferentially processes the CELL UPDATE message and stops theAMR service setup even if the UE 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 continueswith the AMR service setup after the cell update procedure is completed.

Step 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, selectthe P2D_SWITCH(P2D_SWITCH) check box under the parameter Optimization Switch.

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

Step 10 Run the RNC MML command MOD ADJMAP to replace the Iu-PS activation factor table withthe one added in step 9. If the related activation factors are already set to 10%, skip this step.

----End

NOTE


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

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

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

124



the processingbased onCR2284R1, thatis, based on thedescription insection 8.6.6.28of Release 5 TS25.331. In thissection, itdescribes thatthe HFN isincreased by onewhen RB setupis accompaniedby a Timing re-initialized hardhandover. Whenthis switch isturned off, theHFN is notincreased by onewhen RB setupis accompaniedby a Timing re-initialized hardhandover. 11)CDT_MSG_FULL_TRACE.When it ischecked, CDTtrace functionwhich startstracing frommessage RRCCONNECTREQUEST. 12)CR2284R1_COMPATIBLE_SWITCH.CR2284R1causes thecompatibleproblem. if UEis not consistentwith RNCregardingwhether acceptthe CR2284R1



125



or not, it willcause theproblem ofstreaming whenUEs arecommunicatingwith each other.So RNC createsthis switch.when it ischecked, RNC isauto-adaptive toaccept theCR2284R1according to UEversioninformation.The principlesthat RNC judgesUE whether toaccept theCR2284R1 areas follows: R5and above UEaccepts the CR;R99/R4 UE, if itreceives theSTART LISTvalue from RBSETUPCOMPLETE,RNC figures thatUE accepts theCR; R99/R4 UE,if it onlyreceives theSTART valuefrom RBSETUPCOMPLETE,RNC figures thatUE does notaccept the CR;when it is notchecked,whether RNCaccept the CR ornot is according



126



toCR2284R1_SWITCH. Therelationsbetween thesetwo switchesCR2284R1_SWITCH andCR2284R1_COMPATIBLE_SWITCH are asfollows: (1)CR2284R1_COMPATIBLE_SWITCH ischecked, RNC isself-compatible,so theCR2284R1_SWITCH is invalid;(2)CR2284R1_COMPATIBLE_SWITCH is notchecked, theCR2284R1_SWITCH is valid.13)COMBINE_OPERATION_DRD_SWITCH.When it is on,RNC will notreject themessage RBSETUP CMPwithout the IEactive time. 14)UL_INTER_PROTECT_SWITCH.

When it ischecked, RNCwill supporttransferring FastDormancy UEfromCELL_DCH orCELL_FACH toURA_PCH.When it is notchecked, RNCwill not supporttransferring FastDormancy UEfromCELL_DCH orCELL_FACH toURA_PCH. 22)FD_TAC_MATCH_SWITCH.When thisswitch is turnedon, the RNCuses TACmatching todeterminewhether to applythe FASTDORMANCYfunction for prefast dormancy



129



UEs. When thisswitch is turnedoff, the RNCapplies theFASTDORMANCYfunction for prefast dormancyUEs of 3GPPRelease 5 orlater. 23)NONPTT_L1_FAST_SYNC_SWITCH. Whenthis switch isturned on, if aUE sets up anon-PTT serviceon the DCH, theRNC includesthe Post-verificationperiodinformationelement (IE) in aUu message toinstruct the UEto performconcurrentuplink anddownlinksynchronization. When thisswitch is turnedoff, if a UE setsup a non-PTTservice on theDCH, the RNCdoes not includethe Post-verificationperiod IE in a Uumessage. TheUE firstperformsdownlinksynchronizationand then uplink

Meaning:1)LOAD_IRAT_HO_RNC_FILL_TL (Cell LoadInformation TLInput Switch)During inter-RAT handoversfrom 3G cells to2G cells, theRNC canrecordsinformationabout load on 3Gcells in theRELOCATIONREQUIREDcontainer in theTag LengthValue (TLV)format. Whenthe switch isturned on, theRNC records theTag Length inthe container.When the switchis turned off, theRNC does notrecord the TagLength. 2)SEND_IDT_JUDGE_IU_RESET (Switch forTransferringINITIAL UEMessages in theIU Reset State)When the switchis turned on, theRNC discardsthe INITIAL UEmessage from aCN node if the Iuinterface is in thereset state.When the switchis turned off, the



171



RNC handlesthe INITIAL UEmessage from aCN node if the Iuinterface is in thereset state. 3)RNC_RBRECFG_DRD_FAIL_ROLLBACK_SWITCH (RBReconfigurationDRD RollbackSwitch) Whenthe switch isturned on, theRNC supportsrollback causedby faileddirected retrydecisions(DRDs) of RBreconfiguration.When the switchis turned off, theRNC does notsupport rollbackcaused by failedDRDs of RBreconfiguration.4)RNC_CS_QUERY_UE_IMEI_SWITCH (CSIMEI RequestSwitch) Whenthis switch isturned on, theRNC rather thanthe CN sends anIDENTITYREQUESTmessage toobtain theinternationalmobileequipmentidentity (IMEI)of a UE. Note:



172



When the CNchecks the serialnumber of directtransfermessages andtheSEND_MSG_NULL_SWITCHswitch is turnedoff, turning onthis switch leadsto inconsistencyin the serialnumber of directtransfermessagesbetween the CNand the UE. Thiscauses CSservice setupfailures.Therefore, youare not advisedto turn on thisswitch. Beforeturning on thisswitch, test theinterworkingbetween theRNC and theCN. If the CNchecks the serialnumber of directtransfermessages, turnonSEND_MSG_NULL_SWITCHunder"PROCESSSWITCH4" in the"SETURRCTRLSWITCH"command.When the switchis turned off, theRNC does not



173



send anIDENTITYREQUESTmessage toobtain the IMEIof a UE. 5)RNC_PS_QUERY_UE_IMEI_SWITCH (PSIMEI RequestSwitch) Whenthe switch isturned on, theRNC, ratherthan the CN,sends anIDENTITYREQUESTmessage toobtain the IMEIof a UE. Whenthe switch isturned off, theRNC does notsend anIDENTITYREQUESTmessage toobtain the IMEIof a UE. 6)FACH_DTCH_CONGEST_P2D (P2D Switchfor CongestedFACH orDTCH) Whenthe switch isturned on, UEsusing PSservices triggertheCELL_PCH-to-CELL_DCHprocedure (P2Dprocedure forshort) on acongestedFACH or



174



DTCH. Whenthe switch isturned off, UEsusing PSservices do nottrigger the P2Dprocedure on acongestedFACH orDTCH. 7)RNC_RBSETUP_DRD_FAIL_ROLLBACK_SWITCH (RBEstablishmentDRD RollbackSwitch) Whenthe switch isturned on, theRNC supportsrollback causedby failed DRDsof RBestablishment.When the switchis turned off, theRNC does notsupport rollbackcaused by failedDRDs of RBestablishment.8)PS_NOTIFYCN_NOTDOWNSIZE_SWITCH(Switch for NotTriggering RateReductionNegotiationBetween the CNand the RNCAfter a PSService AccessFailure) Whenthe switch isturned on, theaccess rate is notnegotiated



175



between theRNC and the CNif a PS servicefails to beadmitted. Whenthe switch isturned off, theaccess rate isnegotiatedbetween theRNC and the CNif a PS servicefails to beadmitted. 9)ASU_RSP_TIMEOUT_HANDLE_SWITCH(Switch forPerforming theOptimized Soft-HandoverTimeoutProcedure)When the switchis turned on, theRNC considersthat it hasreceived anACTIVE SETUPDATECOMPLETEmessage duringsoft handoverprocedure afterthe message hasexpired. Whenthe switch isturned off,RABs aredirectly releasedduring softhandoverprocedure afterthe ACTIVESET UPDATECOMPLETEmessage hasexpired. 10)
