2 Overview

2.1 IntroductionSome 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/URA_PCH state to reducebattery consumption. Upon receiving the SCRI, the RNC can release the signaling connectionand switch the UEs to idle mode, or the RNC can maintain the signaling connection and switchthe UEs to the CELL_FACH or CELL_PCH/URA_PCH state.

By default, the RNC switches the UEs to idle mode. A UE setting up PS services in idle modeconsumes more signaling resources than that in the CELL_FACH or CELL_PCH/URA_PCHstate. If a large number of UEs are switched between idle mode and the CELL_DCH state,signaling storms may occur. The EFD feature is introduced to switch the UEs to theCELL_FACH or CELL_PCH/URA_PCH state to relieve signaling storms.

The UEs on a live network are classified into the following types:

l UEs that do not send an SCRI message (earlier than 3GPP Release 5)

This type of UE is of a release earlier than 3GPP Release 5 and does not send an SCRImessage after completing data transmission.

l UEs that do not send an SCRI message (3GPP Release 5 and later)

This type of UE is of 3GPP Release 5 or later and does not send an SCRI message aftercompleting data transmission.

l UEs that send an SCRI message (with the "UE Requested PS Data session end" cause value)

This type of UE reads the T323 information element (IE) carried in the system informationblock type 1 (SIB1) message and sends an SCRI message to the RNC after completing datatransmission. The SCRI message carries the "Signaling Connection Release IndicationCause" IE, which is set to "UE Requested PS Data session end." This type of UE complieswith 3GPP Release 8.

T323 determines the interval at which a UE sends an SCRI message. That is, the T323 timerstarts after a UE sends an SCRI message, and SCRI messages with the "UE Requested PSData session end" cause value cannot be sent until T323 expires.

l UEs that send an SCRI message (with other cause values or no cause value)

WCDMA RANEnhanced Fast Dormancy Feature Parameter Description 2 Overview


5

This type of UE does not read the "T323" IE carried in the SIB1 message, and sends anSCRI message to the RNC after completing data transmission.

– The message carries the "Signaling Connection Release Indication Cause" IE and theIE is set to cause values other than "UE Requested PS Data session end."

– The message does not carry the "Signaling Connection Release Indication Cause" IE.

Intelligent UEs that can use EFD are called fast dormancy UEs, and other UEs are called non-fast dormancy UEs. Among the preceding four types of UEs, UEs that do not send an SCRImessage (earlier than 3GPP Release 5) are called non-fast dormancy UEs and the other threetypes are called fast dormancy UEs.

If EFD is not enabled, the RNC releases the signaling connection of a UE and switches the UEto idle mode after receiving an SCRI message from the UE.

If EFD is enabled, the RNC switches a UE to idle mode or to the CELL_FACH, CELL_PCH,or URA_PCH state after receiving an SCRI message from the UE.

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

2.2 BenefitsThis feature can reduce RNC signaling load, NodeB signaling load, and NodeB CE resourceconsumption caused by intelligent UEs.

For example, after the feature is enabled, if the number of PS RAB setups decreases by 70%,the RNC SPU load decreases by 5% to 20% and both the NodeB signaling load and CE resourceconsumption decrease by 10% to 30%.

NOTE

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

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

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 switches the UE to idle mode. 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 is introduced to decrease the RNC signaling processing load. With EFD, the RNC switchesa UE to the CELL_FACH or CELL_PCH/URA_PCH state instead of idle mode upon receivingan SCRI message from the UE. In this case, when the UE periodically sends heartbeat messages,the signaling procedure between the UE and RNC is simplified because the RRC connection ismaintained. As the number of signaling exchange messages decreases, significant CPUresources can be saved for the RNC, and the UE consumes less battery power than a UE in idlemode.

To enable the EFD feature, select the FAST_DORMANCY_SWITCH check box under thePROCESSSWITCH(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCHcommand.

Figure 3-1 shows the signaling processing procedures for fast dormancy UEs before and afterEFD is enabled.

WCDMA RANEnhanced Fast Dormancy Feature Parameter Description 3 Technical Description


7

Figure 3-1 Signaling processing procedures for fast dormancy UEs before and after EFD isenabled

After EFD is enabled, the RNC identifies which UEs can use this feature through either of thefollowing mechanisms:

l Using the Type Allocation Code (TAC)

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 V8.15.0.

TAC (8 digits) SNR (6 digits) Spare (1 digit)

When the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH(BSC6900,BSC6910) parameter is enabled, the RNC determines whether fast dormancyUEs can use EFD based on their TACs. Specifically, upon receiving an IDENTITYREQUEST message from a fast dormancy UE, the RNC checks whether the TAC in theIMEI IE of the message is in the EFD list.

– If so, the UE can use EFD. Upon receiving the SCRI message from the fast dormancyUE, the RNC switches the UE to the CELL_FACH, CELL_PCH, or URA_PCH state.



8

– If not, the UE cannot use EFD.To enable the UE to use EFD, run the ADD UIMEITAC command to set the TAC(BSC6900,BSC6910) parameter to the UE's TAC, set the FastDormancy(BSC6900,BSC6910) parameter to ON, and set the TAC_FUNC(BSC6900,BSC6910)parameter to Fast_Dormancy.

NOTE

Some fast dormancy UEs may have compatibility issues if the RNC switches them to the CELL_FACH,CELL_PCH, or URA_PCH state after these UEs send an SCRI message. As a result, new services cannotbe initiated. This feature was tested only on iPhones and no compatibility issue occurred.

l Checking whether the UEs comply with 3GPP Release 5 or laterTo enable UEs complying with 3GPP Release 5 or later to use EFD, the RNC must switchthese UEs to the CELL_FACH, CELL_PCH, or URA_PCH state or to idle mode uponreceiving the SCRI message from them. The related operations are as follows:

1. Disable the FD_TAC_MATCH_SWITCH under the PROCESSSWITCH(BSC6900,BSC6910) parameter. This adds the TACs of UEs that comply with 3GPPRelease 5 or later to the EFD list so that these UEs can use EFD.

2. Enable the RNC_FD_SCRI_FORCE_REL_SWITCH under thePROCESSSWITCH2(BSC6900,BSC6910) parameter. This enables the RNC toswitch fast dormancy UEs to idle mode upon receiving an SCRI message with nocause value from them.

3. Run the RMV UIMEITAC command to remove TACs whose TAC_FUNC(BSC6900,BSC6910) is set to Fast_Dormancy from the EFD list.

NOTE

You can run the LST UIMEITAC command to view TACs whose TAC_FUNC(BSC6900,BSC6910) is set to Fast_Dormancy.

4 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.

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

l For fast dormancy UEs on the EFD list:

– The RNC switches fast dormancy UEs to idle mode to prevent compatibility issueswhen the RNC receives an SCRI message where the Signaling Connection ReleaseIndication Cause IE is set to "UE Requested PS Data session end" and then anotherSCRI message that does not include the Signaling Connection Release Indication CauseIE.

– The RNC switches UEs from the CELL_DCH or CELL_FACH state to idle mode 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 switches these UEs to the CELL_FACH,CELL_PCH, or URA_PCH state.

If this switch is turned off, the RNC switches these UEs to the CELL_FACH orCELL_PCH/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 switched to the CELL_FACH or CELL_PCH/URA_PCH statefrom the CELL_DCH state.

– After PS data transmission is complete, the RNC switches a UE to CELL_FACH orCELL_PCH/URA_PCH if the UE is in CELL_DCH and the PS inactivity timerPsInactTmrForFstDrmDch(BSC6900,BSC6910) for EFD in CELL_DCH expires.

– After PS data transmission is complete, the RNC switches a UE to CELL_PCH/URA_PCH if the UE is in CELL_FACH and the PS inactivity timerPsInactTmrForFstDrmFach(BSC6900,BSC6910) for EFD in CELL_FACH expires.

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

10

– The RNC does not process an SCRI message where the Signaling Connection ReleaseIndication Cause IE is set to "UE Requested PS Data session end" when the RNC isprocessing other procedures and the SCRIWITHCAUSE_OVERLAP_SWITCH underthe OptimizationSwitch3(BSC6900,BSC6910) parameter in the SETURRCTRLSWITCH command is turned on. Instead, the RNC preferentiallyprocesses the ongoing procedures. After completing the ongoing procedures, the RNCtriggers the state transition procedure if the UE sends the RNC another SCRI messageor the PS inactivity timer expires.

– If a UE is switched to CELL_PCH/URA_PCH and the PS inactivity timerPsInactTmrForPreFstDrm(BSC6900,BSC6910) for EFD in CELL_PCH/URA_PCHexpires, the RNC switches the UE to idle mode. The value of this timer should be lessthan or equal to that of T305(BSC6900,BSC6910), preventing the UE from beingalways in the CELL_PCH/URA_PCH state and unable to enter idle mode.

– If a UE is in CELL_PCH/URA_PCH and has data to send but the conditions for P2D/U2D are not satisfied, the RNC instructs the UE to enter the CELL_FACH state.

– TAC-based P2D/U2D transitions. That is, when the FD_P2D_SWITCH under thePROCESSSWITCH(BSC6900,BSC6910) parameter in the ADD UIMEITACcommand is turned on, a P2D/U2D transition starts if the UE's TAC is identical withthe TAC added to the EFD list by running the ADD UIMEITAC command and the UEexperiences uplink data transmission or has a paging response in the PS domain.

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

– If a UE is in CELL_FACH and send messages whose traffic volume is higher thanFastDormancyF2DHTvmThd(BSC6900,BSC6910), the RNC switches the UE fromCELL_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 UEs not on the EFD list:– If the RNC received the SCRI, the RNC switches the UE to idle mode.– The state transition for UEs not on the EFD list is the same as that for ordinary UEs.

For details, see State Transition Feature Parameter Description.– For details about state transitions due to FACH congestion, see section "FACH

Congestion 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.

UEs with a specified TAC cannot enter the CELL_PCH or URA_PCH state if you set the parameters inthe ADD UIMEITAC command as follows:

l Specify the TAC(BSC6900,BSC6910) parameter.

l Set the TAC_FUNC(BSC6900,BSC6910) parameter to Special_User_Enhance.

l Select the PCH_DISABLED_SWITCH check box under the SpecUserFunctionSwitch(BSC6910,BSC6900) parameter.

Figure 4-1 shows the state transitions for EFD.

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

(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCHcommand is turned on or the FD_TAC_FORCE_D2F_SWITCH underthe PROCESSSWITCH(BSC6900,BSC6910) parameter in the ADDUIMEITAC command is turned on, the RNC triggers a D2F transition.

l If the RNC_EFD_D2F_SWITCH under the PROCESSSWITCH(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCHcommand is turned off and the FD_TAC_FORCE_D2F_SWITCHunder the PROCESSSWITCH(BSC6900,BSC6910) parameter in theADD UIMEITAC command is turned off, the RNC triggers a D2P/D2Utransition.

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

(BSC6900,BSC6910) parameter in the SET URRCTRLSWITCHcommand controls whether the UE is switched to the CELL_PCH orURA_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.

6 Network Impact

System CapacityThis feature can reduce RNC signaling load, NodeB signaling load, and NodeB CE resourceconsumption caused by intelligent UEs. The feature gains depend on network coverage,proportion of intelligent UEs, and traffic model.

Network PerformanceThis feature has the following impacts on network performance:

l Reduced RRC connection setup success rate (The RRC connection setup failure rate doesnot increase.)– On live networks, the service-related RRC connection setup success rate is higher than

the non-service-related RRC connection setup success rate. After this feature is enabled,the number of service-related RRC connection setup attempts significantly decreasesand the number of non-service-related RRC connection setup attempts slightlydecreases. A possible result of this is that the total RRC connection setup success ratedecreases but the number of RRC connection failures does not increase.

– The signaling exchange success rate in poor coverage areas is generally lower than thatin good coverage areas. After this feature is enabled, the number of RRC connectionsetup attempts slightly decreases in poor coverage areas and the number of RRCconnection setup attempts significantly decreases in good coverage areas. A possibleresult of this is that the total RRC connection setup success rate decreases but the numberof RRC connection setup failures does not increase.

l Reduced PS RAB setup success rateThe calculation formula for the PS RAB setup success rate was corrected, as described insection 7.4.1 Requirements. According to the operation and maintenance experience oflive networks, the PS RAB setup success rate of some fast dormancy UEs is higher thanthe average level of the entire network. After this feature is enabled, the number of PS RABsetup attempts significantly decreases. As a result, the total PS RAB setup success rate maydecrease.

l Reduced paging success rateAfter this feature is enabled, a large number of UEs are switched to the CELL_PCH orURA_PCH state. As a result, the number of paging attempts in idle mode significantlydecreases, but the original paging failures cannot be eliminated. A possible consequence

WCDMA RANEnhanced Fast Dormancy Feature Parameter Description 6 Network Impact


17

of this is that the paging success rate in idle mode decreases. The original paging failuresmay be caused by the following:

– UEs that are dropped from the network or abnormally shut down

– Poor coverage

– Multiple RNCs sharing the same LAC or RACl Longer FACH congestion duration

After this feature is enabled, the number of UEs in the CELL_FACH state increases, thetraffic volume on the FACH increases. As a result, the FACH congestion duration mayincrease.

l Increased PS call drop rateThe calculation formula for the PS call drop rate was corrected, as described in section7.4.1 Requirements. Before this feature is enabled, the UE may be switched to idle modebecause it has no PS data transmission before TRB reset. After this feature is enabled, theonline duration of UEs performing PS services increases so that there may be more TRBresets before the PS User Inactive Detecting Timer expires. As a result, PS call drops occur.Therefore, if there are a large number of call drops caused by TRB resets on the live networkbefore this feature is enabled, the PS call drop rate may increase after this feature is enabled.

l Increased HSDPA call drop rateThe calculation formula for the HSDPA call drop rate was corrected, as described in section7.4.1 Requirements. After this feature is enabled, the HSDPA call drop rate may stillincrease.Before this feature is enabled, the HSDPA service is normally released if the UE has nodata to transmit. Then, if the UE has data to transmit (even only a small amount of data),the UE is switched to the CELL_DCH state. After this feature is enabled, a large numberof UEs are switched to the CELL_PCH or URA_PCH state. Afterward, the UEs only needto be switched to the CELL_FACH state if there is a small amount of data to transmit. Asa result, the denominator in the calculation formula for the HSDPA call drop rate decreases.After EFD is enabled, the actual HSDPA service duration basically remains unchanged.As a result, the total number of abnormal HSDPA service releases has few changes. Insummary, the HSDPA call drop rate increases after EFD is enabled.

7 Engineering Guidelines

7.1 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.

7.2 Required InformationNone

7.3 Planning

7.3.1 RF PlanningNone

7.3.2 Network PlanningIt is good practice to maintain load balancing among all frequencies in the network when usingthis feature. If the network is a service-layered network as follows, set Wait RB reconfigurationresponse timer and RL restoration timer in the SET USTATETIMER command to 11000and 15000, respectively. This reduces the number of call drops for fast dormancy UEs in theCELL_FACH or CELL_PCH state.

l F1 carries R99 services.l F2 carries HSPA services.l F2 does not allow UEs in the idle, CELL_FACH, or CELL_PCH state to camp on.

l Calculation Formula Correction for the Call Drop RateBefore EFD is enabled, if the UE has no data to transmit for a specified period of time, itwill be switched from connected mode to idle mode. After EFD is enabled, if the UE hasno data to transmit for a specified period of time, it will be switched from the CELL_FACHor CELL_DCH state to the CELL_PCH or URA_PCH state instead of being switched toidle mode. From the perspective of user experience, the UE has no data to transmit in idlemode, CELL_PCH, and URA_PCH. All scenarios in which the UE should be switchedfrom CELL_DCH to idle mode, CELL_PCH, or URA_PCH are considered PS servicerelease scenarios. For details, see Figure 7-1, Figure 7-2, and Figure 7-3.

Figure 7-2 UEs with no data transmission being switched to CELL_PCH/URA_PCH afterEFD is enabled

Figure 7-3 PS service release scenarios

From the perspective of user experience, switching to CELL_PCH/URA_PCH after EFDis enabled is equivalent to switching to idle mode through normal release before EFD isenabled. Therefore, the calculation formula for the PS call drop rate is changed to thefollowing:– The PS call drop rate measures the ratio of the number of abnormal PS service releases

to the total number of normal and abnormal PS service releases. Its calculation formulais changed to the following:PS Call Drop Ratio with PCH (Cell) = [(VS.RAB.AbnormRel.PS –VS.RAB.AbnormRel.PS.PCH – VS.RAB.AbnormRel.PS.D2P –



21

VS.RAB.AbnormRel.PS.F2P)/(VS.RAB.AbnormRel.PS + VS.RAB.NormRel.PS –VS.RAB.AbnormRel.PS.PCH – VS.RAB.NormRel.PS.PCH + VS.DCCC.D2P.Succ +VS.DCCC.Succ.F2P + VS.DCCC.Succ.D2U + VS.DCCC.Succ.F2U)] x 100%

– The PS R99 call drop rate measures the ratio of the number of abnormal PS R99 servicereleases to the total number of normal and abnormal PS R99 service releases. Itscalculation formula is changed to the following:PS R99 Call Drop Ratio with PCH (Cell) =[(VS.RAB.AbnormRel.PSR99 – VS.RAB.AbnormRel.PS.PCH –VS.RAB.AbnormRel.PS.R99D2P –VS.RAB.AbnormRel.PS.F2P)/(VS.RAB.AbnormRel.PSR99 +VS.RAB.NormRel.PSR99 – VS.RAB.AbnormRel.PS.PCH –VS.RAB.NormRel.PS.PCH + VS.HSDPA.F2H.Succ + VS.HSDPA.D2H.Succ +VS.PSR99.D2P.Succ + VS.DCCC.Succ.F2P + VS.DCCC.Succ.F2U)] x 100%

– The HSDPA call drop rate measures the ratio of the number of abnormal HSDPA servicereleases to the total number of normal and abnormal HSDPA service releases. Itscalculation formula is changed to the following:HSDPA Service Drop Ratio with PCH (Cell) = [(VS.HSDPA.RAB.AbnormRel –VS.HSDPA.RAB.AbnormRel.H2P)/(VS.HSDPA.RAB.AbnormRel +VS.HSDPA.RAB.NormRel + VS.HSDPA.HHO.H2D.SuccOutIntraFreq +VS.HSDPA.HHO.H2D.SuccOutInterFreq + VS.HSDPA.H2D.Succ +VS.HSDPA.H2F.Succ + VS.HSDPA.H2P.Succ)] x 100%

– The HSUPA call drop rate measures the ratio of the number of abnormal HSUPA servicereleases to the total number of normal and abnormal HSUPA service releases. Itscalculation formula is changed to the following:HSUPA Call Drop Ratio with PCH (Cell) = [(VS.HSUPA.RAB.AbnormRel –VS.HSUPA.RAB.AbnormRel.E2P)/(VS.HSUPA.RAB.AbnormRel +VS.HSUPA.RAB.NormRel + VS.HSUPA.HHO.E2D.SuccOutIntraFreq +VS.HSUPA.HHO.E2D.SuccOutInterFreq + VS.HSUPA.E2F.Succ +VS.HSUPA.E2D.Succ + VS.HSUPA.E2P.Succ)] x 100%

l Calculation Formula Correction for the PS RAB Setup Success RateAfter EFD is enabled, a large number of UEs will be switched to the CELL_PCH orURA_PCH state. Then, a large number of UEs will be switched from CELL_PCH orURA_PCH to CELL_FACH or CELL_DCH to establish PS services, instead of releasingPS RAB setup and then reinitiating PS RAB setup. From the perspective of user experience,RAB setup, P2F, and P2D are all processes in which UEs initiate services. Therefore, thecalculation formula for the PS RAB setup success rate should be corrected. The PS RABsetup success rate measures the ratio of the number of successful PS service initiations tothe number of attempted PS service initiations. Its calculation formula is changed to thefollowing:PS RAB Setup Success Ratio with PCH (Cell) = [(VS.RAB.SuccEstabPS.Cell +VS.DCCC.P2F.Succ + VS.DCCC.URAP2F.Succ + VS.DCCC.P2D.Succ +VS.DCCC.URAP2D.Succ)/(VS.RAB.AttEstabPS.Cell + VS.DCCC.P2F.Att +VS.DCCC.URAP2F.Att + VS.DCCC.P2D.Att + VS.DCCC.URAP2D.Att)] x 100%

l Adding a Second S-CCPCHAfter EFD is enabled, both the number of UEs in the CELL_FACH state and the trafficvolume on the FACH increase. As a result, it is possible that the user plane on the FACHis congested and the RRC connection setup fails. Therefore, you need to add an S-CCPCHdedicated to theFACH to alleviate FACH congestion.



22

– If there is only one S-CCPCH on the network, it is recommended that you add a secondS-CCPCH before enabling EFD.

– Add the second S-CCPCH at least three days before enabling EFD, because the additiontakes a long time.

– Add the second S-CCPCH during off-peak hours (for example, in the early morning)because cells need to be deactivated, which interrupts services.

– After the second S-CCPCH is added, system information on the UE side may not beupdated because the Value Tag saved on the UE is consistent with that carried in thecurrently broadcast system information. As a result, the UE does not know that the S-CCPCH has changed, thereby affecting the RRC connection setup success rate.According to section 8.1.1 "Broadcast of system information" in 3GPP TS 25.331, thelongest period during which system information is saved on the UE is six hours. Whenthe longest period is exceeded, the UE reads system information again. Therefore, ittakes six hours for the RRC connection setup success rate to restore to normal. To avoidthis problem, you need to enable theCELL_SIB_NOT_UPD_NCELL_CHG_SWITCH. If this switch is enabled, systeminformation is not updated in the current cell when neighboring cells are being activatedor deactivated.

For details about adding a Second S-CCPCH, see section (Mandatory) Adding a SecondS-CCPCH.

Activation Observation Through Counters

You can determine whether the EFD function has taken effect by observing theVS.DCCC.FastDormUe.DF2P.Att and VS.DCCC.FastDormUe.DF2P.Succ counters. If thevalues of these two counters are not 0, the EFD function has taken effect.

7.4.7 Deactivation

Deactivating the EFD Functionl Disable the EFD function switch.

Run the RNC MML command SET URRCTRLSWITCH to deselect theFAST_DORMANCY_SWITCH check box under the Process switch parameter todisable the EFD function switch.

l Restore other EFD-related parameters to the settings before feature activation.

Rolling Back the Double S-CCPCH Strategy to the Single S-CCPCH Strategy

Generally, it is not recommended that you roll back the double S-CCPCH strategy to the singleS-CCPCH strategy. If you have to, perform the following steps:

After the second S-CCPCH is added, system information on the UE side may not be updatedbecause the Value Tag saved on the UE is consistent with that carried in the currently broadcastsystem information. As a result, the UE does not know that the S-CCPCH has changed, therebyaffecting the RRC connection setup success rate. Generally, the UE will update systeminformation six hours later, and the RRC connection setup success rate can be restored to normalby then. To avoid this problem, you need to enable theCELL_SIB_NOT_UPD_NCELL_CHG_SWITCH. If this switch is enabled, systeminformation is not updated in the current cell when neighboring cells are being activated ordeactivated.

Step 1 Before rolling back the double S-CCPCH strategy to the single S-CCPCH strategy, run the RNCMML command SET UNBMPARA to select theCELL_SIB_NOT_UPD_NCELL_CHG_SWITCH check box under the Reliability Switchparameter to enable the Neighboring Cell Status Change Not Update SIB Switch.

Step 2 Run the script that is used to roll back the double S-CCPCH strategy to the single S-CCPCHstrategy for all cells. (The following describes the parameter configurations separately: whenCBS is enabled and when CBS is disabled.)

Step 3 Run the RNC MML command SET UNBMPARA to deselect theCELL_SIB_NOT_UPD_NCELL_CHG_SWITCH check box under the Reliability Switchparameter to disable the Neighboring Cell Status Change Not Update SIB Switch.

Whenthis switch is set to on, the number of FACH UEs in acell is limited not only by the FACH UE numberspecification but also by the CELL_FACH UE numberspecification (CELL_FACH UEs include both E-FACHUEs and FACH UEs). That is, the total number ofFACH UEs and E-FACH UEs in a cell cannot exceedthe CELL_FACH UE number specification. When thisswitch is set to off, the number FACH UEs in a cell isonly limited by the FACH UE specification. 28.PERFENH_RELOCINUSER_LDRPRE_OPT_SWITCH(Optimization Switch for Static Relocation UserSelection for LDR and Preemption): Whether tooptimize the user selection algorithm for LDR andpreemption. When this switch is set to on, the userselection algorithm for LDR and preemption isoptimized. That is, the actual priority of static relocationUEs is used for LDR and preemption, which makes theuser priority recognition more accurate. When thisswitch is turned off, default user priority is used for LDRand preemption. 29.PERFENH_SOFTERHO_CE_OPT_SWITCH:Calculation method of consumed CE resources. If thisparameter is set to ON, the RNC correctly calculates theconsumed CE resources.

Whenthis switch is set to on, the number of FACH UEs in acell is limited not only by the FACH UE numberspecification but also by the CELL_FACH UE numberspecification (CELL_FACH UEs include both E-FACHUEs and FACH UEs). That is, the total number ofFACH UEs and E-FACH UEs in a cell cannot exceedthe CELL_FACH UE number specification. When thisswitch is set to off, the number FACH UEs in a cell isonly limited by the FACH UE specification. 28.PERFENH_RELOCINUSER_LDRPRE_OPT_SWITCH(Optimization Switch for Static Relocation UserSelection for LDR and Preemption): Whether tooptimize the user selection algorithm for LDR andpreemption. When this switch is set to on, the userselection algorithm for LDR and preemption isoptimized. That is, the actual priority of static relocationUEs is used for LDR and preemption, which makes theuser priority recognition more accurate. When thisswitch is turned off, default user priority is used for LDRand preemption. 29.PERFENH_SOFTERHO_CE_OPT_SWITCH:Calculation method of consumed CE resources. If thisparameter is set to ON, the RNC correctly calculates theconsumed CE resources. If this parameter is set to OFF,the CE resources consumed on the link that is deletedafter a soft handover are not calculated. As a result, theavailable CE resources increase and excess users accessthe cell. 30.PERFENH_LCGCE_RSRC_OPT_SWITCH: LCG CEresource optimization switch for preempted UEs. Whenthis switch is set to on, the RNC correctly maintains theLCG CE resources used by a UE after an RRCconnection setup. If the UE is preempted, theseresources are provided to the preempting UE. When thisswitch is set to off, the RNC cannot update the LCG CEresources used by a UE in time, which leads to incorrect

When this switch is turned on,the RNC immediately calculates the resource consumedby the users who stop queuing, ensuring that the RNCcorrectly calculates cell resources. When this switch isturned off, the RNC does not immediately calculate theresource consumed by the users who stop queuing. Asa result, the consumed cell resources are more than theresources recorded on the RNC, and excessive usersaccess the cell. 32.PERFENH_SRB_OVER_HSDPA_DOFF_OPT_SWITCH: Whether to optimize the Default DPCH OffsetValue (DOFF) allocation algorithm for a specified UE.This switch is set to on by default. When this switch isset to off, the RNC uses the original DOFF allocationalgorithm for a new UE or a C2D UE whose SRBs arecarried over HSDPA (C2D refers to an F2D or P2D statetransition). This cannot ensure even DOFF distribution.When this switch is set to on, the RNC uses theoptimized DOFF allocation algorithm for a new UE ora C2D UE whose SRBs are carried over HSDPA. Thisensures even DOFF distribution. DisuseStatement:PERFENH_FACH_USER_NUM_SWITCH will be replaced with FACH_60_USER_SWITCH("CacSwitch":FACH_60_USER_SWITCH)("SETUCACALGOSWITCH") in later versions. Theconfiguration interface in this version supports deliveryof the settings of both this parameter andFACH_60_USER_SWITCH("CacSwitch":FACH_60_USER_SWITCH)("SETUCACALGOSWITCH"). If the setting of only thisparameter is delivered, the system automaticallyreplaces this parameter withFACH_60_USER_SWITCH("CacSwitch":FACH_60_USER_SWITCH)("SETUCACALGOSWITCH") and the setting takes effect. Ifthe setting of SET UCACALGOSWITCH("CacSwitch":FACH_60_USER_SWITCH)("SETUCACALGOSWITCH") is delivered, the setting ofonly SET UCACALGOSWITCH("CacSwitch":FACH_60_USER_SWITCH)("SETUCACALGOSWITCH") takes effect in the system.Therefore, this parameter is not recommended.

CR2284R1causes the compatible problem. if UE is not consistentwith RNC regarding whether accept the CR2284R1 ornot, it will cause the problem of streaming when UEsare communicating with each other. So RNC creates thisswitch. when it is checked, RNC is auto-adaptive toaccept the CR2284R1 according to UE versioninformation. The principles that RNC judges UEwhether to accept the CR2284R1 are as follows: R5 andabove UE accepts the CR; R99/R4 UE, if it receives theSTART LIST value from RB SETUPCOMPLETE,RNC figures that UE accepts the CR;R99/R4 UE, if it only receives the START value fromRB SETUP COMPLETE,RNC figures that UE does notaccept the CR; when it is not checked, whether RNCaccept the CR or not is according toCR2284R1_SWITCH. The relations between these twoswitches CR2284R1_SWITCH andCR2284R1_COMPATIBLE_SWITCH are as follows:1: This switch is turned on. RNC is self-compatible, sothe CR2284R1_SWITCH is invalid; 0: This switch is

Timer after which the rate of PS BE services whoseuplink and downlink channel types are both DCHs willbe adjusted to the low-activity rate. When this switch isturned off, the value is equal to MAX(BeE2FState-TransTimer, BeD2FStateTransTimer). When thisswitch is turned on, the value is equal toBeD2FStateTransTimer. When a BE service ratereduces to the DCCC rate threshold, the low-activityrate, as substitution to a D2F transition, is used for theBE service because state transition has not been enabledor the UE processing CS services cannot transit to theCELL_FACH state. The timer value and measurementcontrols for low-activity rate adjustment use thecorresponding parameter values involved in the D2Ftransitions. 7.PERFENH_CS_TRIG_PS_P2D_ZERO_SWITCH:Whether a PS BE service is limited to 0 kbit/s on theDCH after a UE that has the PS BE service performs aCELL_PCH/URA_PCH-to-CELL-DCH (P2D) statetransition triggered by a CS service setup. When thisswitch is turned off, the PS BE service is limited to 8kbit/s on the DCH after the UE performs a P2D statetransition. When this switch is turned on, the PS BEservice is limited to 0 kbit/s on the DCH after the UEperforms a P2D state transition. 8.PERFENH_FACH_CONG_D2IDLE_SWITCH:Whether the RNC releases all resources for a UE whenthe FACH is congested. When this switch is turned on,the RNC releases all resources for a UE if the followingconditions are met: The UE performs a CELL_DCH-to-CELL_FACH state transition. The FACH is congested.The UE is processing a non-real-time PS service thathas a traffic volume of 0 bytes. 9.PERFENH_P2D_FAIL_RETRY_SWITCH: Whethera UE is allowed to access an inter-frequency co-coverage cell using DRD or channel fallback after P2Dstate transition admission fails. When this switch isturned off, the UE remains in the CELL_PCH state afterP2D state transition admission fails. 10.PERFENH_PTT_IUR_D2F_SWITCH: Whether aPTT user can perform a CELL_DCH-to-CELL_FACH(D2F for short) state transition when Iur CCH isdisabled during a soft handover over the Iur interface.Assume that this switch is turned on. If the DRNC cellserves as the best cell, DSCR is triggered. If the SRNCcell serves as the best cell, D2F is triggered. When thisswitch is turned off, the original flow keeps unchanged.

When this switch is turned off,the low-activity rate algorithm can be used on the UEthat uses DCHs in both the uplink and downlink. 12.PERFENH_SRB_FAST_HRETRY_AFTER_DRD_SWITCH: Whether the RNC triggers channelreconfiguration for the SRBs to switch from the DCHto an HSPA channel immediately when the type of achannel for carrying SRBs during a DRD procedure islimited. When this switch is turned off, channelreconfiguration is not triggered and the SRBs are carriedon the DCH. When this switch is turned on, the RNCtriggers channel reconfiguration for the SRBs to switchfrom the DCH to an HSPA channel immediately afterthe DRD procedure. 13.PERFENH_PTT_H2F_OPT_SWITCH: Whether thetraffic and throughput are measured during a statetransition from CELL_DCH to CELL_FACH (D2F forshort) when PTT services are carried on HSPAchannels. When this switch is turned off, the traffic andthroughput will not be measured during the D2F statetransition triggered by PTT services. When this switchis turned on, the traffic and throughput will be measuredduring the D2F state transition, which prevents the UEfrom transiting to CELL_FACH if the UE has data totransmit. In this case, if data transmission occurs duringthe D2F state transition, the RNC stops the D2F statetransition. 14.PERFENH_IUR_DB_TICK_OPT_SWITCH:Whether the algorithm for optimizing the method ofsaving the information about neighboring cells of a cellunder the DRNC during a handover over Iur is enabledso that the CPU load on the SPUb board becomesnormal. When this switch is turned off, the algorithm isdisabled and the RNC saves the information aboutneighboring cells in the original way. When this switchis turned on, the algorithm is enabled. 15.PERFENH_P2D_LIMIT_ON_DCH_LOWRATE_SWITCH: Whether the PS BE service rate is limited to alow level after the UE transits from CELL_PCH toCELL_DCH (P2D for short).

When thisswitch is turned off, the delay timer does not start. Whenthis switch is turned on, the RNC starts the delay timerafter the algorithm for fairness-based handovers fordifferentiated HSUPA TTI users us used to establish ormodify a throughput measurement. The handover fromHSUPPA 2 ms TTI users to 10 ms HSUPPA TTI userscannot be triggered when the delay timer is running. 17.PERFENH_BASE_ADM_CE_TTI2MS_LIMIT_SWITCH: Whether the RNC considers CE resourcecongestion status of the target cell for admitting HSUPAUEs when determining whether HSUPA servicessupport 2 ms TTI. When this switch is turned off, theRNC does not consider CE resource congestion statusof the target cell when determining whether the HSUPAservices support 2 ms TTI. When this switch is turnedon, the RNC considers CE resource congestion status ofthe target cell when determining whether the HSUPAservices support 2 ms TTI. If the CE resources arecongested, only HSUPA 10 ms TTI UEs are admitted.18.PERFENH_OLPC_SIRTAR_RESEND_SWITCH:Whether the RNC sends the FP data frames that containthe information element (IE) "Sir Target" to the NodeBafter service setup or reconfiguration succeeds and theNodeB then adjusts inner loop power control based onthe configured target SIR value and actual target SIRvalue. When this switch is turned off, the FP data framesdo not contain the IE "Sir Target".

When this switch isturned off, the value is equal to MAX(BeE2FState-TransTimer, BeD2FStateTransTimer). When thisswitch is turned on, the value is equal toBeD2FStateTransTimer. When a BE service ratereduces to the DCCC rate threshold, the low-activityrate, as substitution to a D2F transition, is used for theBE service because state transition has not been enabledor the UE processing CS services cannot transit to theCELL_FACH state. The timer value and measurementcontrols for low-activity rate adjustment use thecorresponding parameter values involved in the D2Ftransitions. 7.PERFENH_CS_TRIG_PS_P2D_ZERO_SWITCH:Whether a PS BE service is limited to 0 kbit/s on theDCH after a UE that has the PS BE service performs aCELL_PCH/URA_PCH-to-CELL-DCH (P2D) statetransition triggered by a CS service setup. When thisswitch is turned off, the PS BE service is limited to 8kbit/s on the DCH after the UE performs a P2D statetransition. When this switch is turned on, the PS BEservice is limited to 0 kbit/s on the DCH after the UEperforms a P2D state transition. 8.PERFENH_FACH_CONG_D2IDLE_SWITCH:Whether the RNC releases all resources for a UE whenthe FACH is congested. When this switch is turned on,the RNC releases all resources for a UE if the followingconditions are met: The UE performs a CELL_DCH-to-CELL_FACH state transition. The FACH is congested.The UE is processing a non-real-time PS service thathas a traffic volume of 0 bytes. 9.PERFENH_P2D_FAIL_RETRY_SWITCH: Whethera UE is allowed to access an inter-frequency co-coverage cell using DRD or channel fallback after P2Dstate transition admission fails. When this switch isturned off, the UE remains in the CELL_PCH state afterP2D state transition admission fails. 10.PERFENH_PTT_IUR_D2F_SWITCH: Whether aPTT user can perform a CELL_DCH-to-CELL_FACH(D2F for short) state transition when Iur CCH isdisabled during a soft handover over the Iur interface.Assume that this switch is turned on. If the DRNC cellserves as the best cell, DSCR is triggered. If the SRNCcell serves as the best cell, D2F is triggered. When thisswitch is turned off, the original flow keeps unchanged.

When this switch is turned off, channelreconfiguration is not triggered and the SRBs are carriedon the DCH. When this switch is turned on, the RNCtriggers channel reconfiguration for the SRBs to switchfrom the DCH to an HSPA channel immediately afterthe DRD procedure. 13.PERFENH_PTT_H2F_OPT_SWITCH: Whether thetraffic and throughput are measured during a statetransition from CELL_DCH to CELL_FACH (D2F forshort) when PTT services are carried on HSPAchannels. When this switch is turned off, the traffic andthroughput will not be measured during the D2F statetransition triggered by PTT services. When this switchis turned on, the traffic and throughput will be measuredduring the D2F state transition, which prevents the UEfrom transiting to CELL_FACH if the UE has data totransmit. In this case, if data transmission occurs duringthe D2F state transition, the RNC stops the D2F statetransition. 14.PERFENH_IUR_DB_TICK_OPT_SWITCH:Whether the algorithm for optimizing the method ofsaving the information about neighboring cells of a cellunder the DRNC during a handover over Iur is enabledso that the CPU load of the CP subsystem becomesnormal.

This switch is introduced to complywith the Change Request (CR) specified in the relatedprotocol, that is, three substreams need to be establishedfor a WB AMR service. The switchCMP_WBAMR_SUBFLOW_SWITCH in this versionsupports configuration synchronization and delivery,but the RNC does not use this switch any longer. Futureversions do not support this switch. Therefore, it isrecommended that users avoid using this switch. 8.CMP_IUR_CELLCAP_BITMAP_TRANSFORM_SWITCH: The switch is used to solve the problem thatdifferent vendors' RNCs interpret the cell capabilitybitmap differently on the Iur interface. When the switchis set to ON, the RNC interprets the cell capabilitybitmap in a sequence opposite to that specified by therelated protocol. When the switch is set to OFF, theRNC interprets the cell capability bitmap in thesequence specified by the related protocol. 9.CMP_MOCN_PLMN_SEL_SWITCH: When theswitch is set to ON, if the UE supports the MOCNfeature, the SRNC preferentially uses the PLMN of theUE's homing operator in the RELOCATIONREQUIRED message, and the TRNC preferentiallyuses the PLMN of the UE's homing operator in theLOCATION REPORT message and the DIRECTTRANSFER message during relocation; if the UE doesnot support the MOCN feature, the SRNC and theTRNC preferentially use the common operator's PLMNin these above messages. When the switch is set to OFF,the SRNC preferentially uses the PLMN of the UE'shoming operator in the RELOCATION REQUIREDmessage, and the TRNC preferentially uses the PLMNof the UE's homing operator in the LOCATIONREPORT message, but the TRNC preferentially usesthe common operator's PLMN in the DIRECTTRANSFER message during relocation. 10.CMP_LOSSLESS_RELOC_RLCPDUSIZECHG_SWITCH: When the switch is set to ON, the RNC sets the"Support for lossless SRNS relocation or for lossless DLRLC PDU size change" IE transmitted on the Uuinterface to TRUE only if the UE supports both losslessSRNS relocation and downlink RLC PDU size change.When the switch is set to OFF, the RNC sets the
