2-2

After a radio resource control (RRC) connection is set up, the RNC monitors UE activities and uses the UE state transition function to change the UE state (WRFD-010202 UE State in Connected Mode).

A UE state transition is triggered by the traffic volume, timer, or user mobility. The trigger conditions for UE state transitions are described as follows:

Traffic volume report from the UE

Event 4A: The traffic volume is greater than the event 4A threshold.

Event 4B: The traffic volume is less than the event 4B threshold.

Cell reselection

If the number of cell reselections exceeds the specified threshold during the specified period (timer), the UE is considered to be in the state of frequent cell reselections.

Paging/Data

There is data to be transmitted.

Overload

When a cell is overloaded, the RNC may transit the UE state from CELL_DCH (DCH/HS-DSCH/E-DCH) to CELL_FACH (FACH) to relieve the load.

Table 2-1 lists the UE state transition types.

State Transition 3 Technical Description



3-1

3 Technical Description

3.1 UE State Transition Switches

SET UCORRMALGOSWITCH (DraSwitch) defines the following RNC-level switches for dynamic resource allocation:

DRA_PS_BE_STATE_TRANS_SWITCH: controls state transition for UEs performing BE services.

DRA_PS_NON_BE_STATE_TRANS_SWITCH: controls state transition for UEs performing non-BE services (PS real-time service).

DRA_HSDPA_STATE_TRANS_SWITCH: controls state transition from HS-DSCH to FACH.

This switch is valid only when either DRA_PS_BE_STATE_TRANS_SWITCH, or DRA_PS_NON_BE_STATE_TRANS_SWITCH, or both of them are turned on. DRA_PS_BE_STATE_TRANS_SWITCH is turned on for BE services, and DRA_PS_NON_BE_STATE_TRANS_SWITCH is turned on for non-BE services.

DRA_HSUPA_STATE_TRANS_SWITCH: controls state transition from E-DCH to FACH.

This switch is valid only when either of the following switches or both of them are turned on:

DRA_PS_BE_STATE_TRANS_SWITCH, which is turned on for BE services.

DRA_PS_NON_BE_STATE_TRANS_SWITCH, which is turned on for non-BE services.

When the previous switches are turned on:

If DRA_DCCC_SWITCH is set to 1 and the dynamic channel adjustment strategy (DcccStg) is set to RATE_UP_AND_DOWN_ON_DCH, the UE state transition function starts working when the UL/DL rate is less than or equal to the UL/DL rate threshold for DCCC (UlDcccRateThd/DlDcccRateThd).

If DRA_DCCC_SWITCH is set to 1 and DcccStg is set to RATE_UP_ONLY_ON_DCH, the UE state transition function always works.

If DRA_DCCC_SWITCH is set to 0, the UE state transition function always works.

If the timers for online detection are set to be small values for inactive PS services, the RRC connection may be released before UE state transition. The timers for online detection can be set by using the SET UPSINACTTIMER command.

SET UUESTATETRANS is used to set the UE RRC state transition parameters (RNC-level).

SET UUESTATETRANSTIMER is used to set the UE RRC state transition timers (RNC-level).

3.2 D2F State Transition

Figure 3-1 shows the D2F state transition.

WCDMA RAN




3-2

Figure 3-1 D2F state transition

B

When receiving a report on event 4B, the RNC starts the timer for D2F state transition and the counters for UL and DL event 4B reports. If the numbers of UL and DL event 4B reports are greater than or equal to the D2F transition threshold before the timer expires, then the D2F state transition is performed when the timer expires.

The D2F state transition threshold is the rounded-down value obtained by using the following equation:

D2F transition threshold = D2F transition time/(Time to trigger + Pending time after trigger) x State transition traffic redundancy coefficient

In this equation:

The D2F state transition time, time to trigger, and pending time after trigger are specified by the parameters listed in Table 3-1.

The state transition traffic redundancy coefficient is used to prevent false detection that a UE is in the low-activity state due to the loss of measurement reports. This coefficient is set to 80%.

The parameters related to event 4B are set to their respective values for the UL and DL. The parameters include the time to trigger, pending time after trigger, and threshold. An example for BE services: if the UL channel is DCH and the DL channel is HS-DSCH, the parameter configurations for BE services on the DCH as listed in Table 3-1 are used for the UL, and the parameter configurations for BE services on the HS-DSCH as listed in Table 3-1 are used for the DL.

State transitions from E-DCH to FACH and from DCH to FACH are similar. The difference is that the event 4B measurement for state transition from E-DCH to FACH is based on the throughput with the throughput measurement period being specified by E2FThrouMeasPeriod. In addition, the threshold of event 4B is based on the throughput and is specified by E2FThrouThd.

To prevent ping-pong state transitions between CELL_DCH and CELL_FACH, turn on the switch PERFENH_H2F_OPT_SWITCH under the PerfEnhanceSwitch parameter in the SET UCORRMPARA command and disable HSUPA DCCC in the uplink. After the switch PERFENH_H2F_OPT_SWITCH is turned on, starting event 4a measurement also starts event 4b measurement. If the RNC receives an event 4a report before the D2F state transition timer expires, the uplink throughput is higher than HSUPA4AThrouThd or the downlink throughput is higher than HSDPA4ATvmThd. In this case, the RNC stops the D2F state transition timer to prevent unnecessary state transitions.

3.3 Low Activity State

For BE services, if DRA_PS_BE_STATE_TRANS_SWITCH is set to 0 or the UE has other services that do not allow UE state transition, UE state transition cannot be performed. If the numbers of UL and DL event 4B reports are greater or equal to the D2F transition threshold before the transition timer expires, the rate can be changed to the low activity rate.

For a single service:

For BE service on the DCH (UL and DL), the UL and DL rates can be changed to the low-activity rate threshold (LittleRateThd).

For BE service on the DCH (UL) and HS-DSCH (DL), only the UL rate can be changed to LittleRateThd.

For BE service on the E-DCH (UL) and DCH (DL), only the DL rate can be changed to LittleRateThd.

Note that if LittleRateThd is greater than or equal to UlDcccRateThd or DlDcccRateThd, the rate cannot be changed to LittleRateThd.

If LittleRateThd is excessively high, excessive resources are occupied for a long time even when no data is transmitted, leading to network congestion. If LittleRateThd is excessively low, the throughput is lower than the expected value when the UE starts transmitting data again, even though less radio resources are consumed.

For combined services:

If a CS service is involved, the UE stays in the CELL_DCH state and D2F state transition is not allowed. If a PS service meets the conditions for D2F state transition, the RNC reduces the data rate of PS services to the low activity rate.

WCDMA RAN




3-4

If only PS services are involved and the state transition switches are turned off, the RNC reduces the data rate of PS services to the low activity rate.

3.4 F2P State Transition

F2P state transition is applicable to BE services in the PS domain.

F2P state transition is similar to D2F state transition.

When receiving a report that event 4B occurs and the traffic volume is zero, the RNC starts the timer for F2P state transition and the counters for UL and DL event 4B reports. If the numbers of UL and DL event 4B reports are greater than the F2P state transition threshold before the timer expires, the F2P state transition is performed when the timer expires.

The F2P state transition threshold is the rounded-down value obtained by using the following equation:

F2P transition threshold = F2P transition time/(Time to trigger + Pending time after trigger) x State transition traffic redundancy coefficient

Table 3-2 lists the parameters related to F2P state transition.

If the cell is in the overload or congestion state, F2D state transition is not allowed.

3.5 P2U State Transition

P2U state transition is applicable to BE services in the PS domain.

Before the state transition, the UE is in the CELL_PCH state. During the cell reselection, the UE sends the CELL UPDATE messages. The RNC starts a timer (CellReSelectTimer) and counts the number of CELL UPDATE messages with the cause value of cell reselection. When the timer expires, the number of CELL UPDATE messages may be above the threshold (CellReSelectCounter). In this case, the RNC initiates a state transition when the UE sends the CELL UPDATE message again.

The P2U state transition involves the transient state CELL_FACH, in which necessary signaling interactions are performed.

3.6 P2F and U2F State Transition

P2F and U2F state transitions are performed when UTRAN pages the UE or when the UE needs to exchange information with the UTRAN. No parameters are involved.

When the switch RSVDBIT1_BIT20 of RsvdPara1 in the SET URRCTRLSWITCH command is turned on and the UE tries to originate or terminate a CS service and the FACH is congested, the RNC instructs the UE to perform a P2D (instead of P2F) state transition.

When the switch FACH_DTCH_CONGEST_P2D of PROCESSSWITCH2 in the SET URRCTRLSWITCH command is turned on and the UE tries to originate or terminate a PS service and the FACH is congested, the RNC instructs the UE to perform a P2D (instead of P2F) state transition..

WCDMA RAN




3-5

3.7 F2D State Transition

The F2D state transition is performed when the UTRAN receives an event 4A report triggered by the UL or DL traffic volume. The RNC determines the transport channel (DCH, HS-DSCH, or E-DCH) and the target rate.

Table 3-3 lists the target rates for F2D state transition.

RtF2DHTvmThd UL target rate (DCH) = MBR

DL target rate (DCH) = MBR

BE service on the E-DCH

BeF2ETvmThd UL target rate (E-DCH) = min (HSUPA rate adjustment set) if HSUPA_DCCC_SWITCH is set to 1

UL target rate (E-DCH) = MBR if HSUPA_DCCC_SWITCH is set to 0.

DL target rate (DCH) = min (MBR, DL rate threshold for DCCC)

DL target rate (H-DSCH) = MBR

3.8 D2D State Transition

For HSDPA and HSUPA, there are two more states: CELL_DCH (with HS-DSCH) and CELL_DCH (with E-DCH).

Figure 3-2 shows how D2D state transition is implemented.

Type Trigger Condition

E2D During a RAB setup, RAB is carried over the E-DCH but resources are insufficient.

During a RAB setup, RAB is carried over the E-DCH but the coverage is insufficient. For details, see the Radio Bearers Feature Parameter Description.

After an HSUPA RAB setup, if the radio coverage is poor during HSUPA data transmission, refer to the descriptions below this table.

The E-DCH serving cell (the best cell) has changed.

The new best cell does not support the E-DCH.

The new best cell does not have enough resources for the E-DCH.

D2E In the preceding E2D scenarios, the RNC may shift the UE from the DCH to the E-DCH.

Periodic attempts to reconfigure to the E-DCH (timer)

Traffic volume (event 4A)

If a UE reports event 6B2 and event 4A and the UE services can be carried on the E-DCH, then the RNC shifts the UE from the DCH to the E-DCH when the transmission rate increases.

H2D RABs are carried over the HS-DSCH but resources are insufficient.

The HS-DSCH serving cell (the best cell) has changed.

The new best cell does not support the HS-DSCH.

The new best cell does not have enough resources for the HS-DSCH.

Periodic attempts to reconfigure to the HS-DSCH (timer)

Traffic volume (event 4A)

Coverage-based Fallback from the E-DCH to the DCH

The coverage-based fallback from the E-DCH to the DCH algorithm is introduced to improve uplink coverage performance of a single UE during HSUPA BE service data transmission. This algorithm is controlled by ReservedSwitch0: RESERVED_SWITCH_0_BIT7.

During HSUPA BE service data transmission, BE service falls back from the E-DCH to the DCH when both the following conditions are met:

The UE reports 6A event.

The UE does not report 6B event after the 6A event.

The UE reports 4B for all HSUPA BE services.

Other services on the UE also fall back to the DCH.

The formula for calculating the threshold of event 6A is as follows:

Threshold of event 6A/6B = Maximum UE transmit power Relative threshold of event 6A for BE service

Where

Maximum UE transmit power is configured by MaxAllowedUlTxPower.

For 2ms TTI, the relative threshold of event 6A for BE service is BeThd6A1, and that for 10 ms TTI is BeThd6A2.

WCDMA RAN




3-7

For 2ms TTI, the relative threshold of event 6A for BE service is BeThd6B1, and that for 10 ms TTI is BeThd6B2.

The threshold of event 4B is E2DThrou4BThd.

A fallback from E-DCH to DCH occurs only in the current cell, which means the inter-frequency directed retry decision (DRD) is not performed.

If the switch for coverage-based fallback from the E-DCH to the DCH (ReservedSwitch0: RESERVED_SWITCH_0_BIT7) is enabled, the algorithm for coverage-based dynamic TTI adjustment of BE services automatically disables. For details about the algorithm for coverage-based dynamic TTI adjustment of BE services, see HSUPA TTI Selection Feature Parameter Description.

Coverage-based Switchback from DCH to the E-DCH

After a UE falls back to the DCH from the E-DCH, the UE does not periodically attempt to switch back to the E-DCH. When the uplink coverage recovers, the UE will be switched back to the E-DCH from the DCH. If the UE reports the event 6B and 4A and does not report 6A afterward, informs the UE of uplink coverage recovery.

The formula for calculating the threshold of event 6B is as follows:

Threshold of event 6B = Maximum UE transmit power Relative threshold of event 6B for BE service (ReservedU8Para1 in SET UCORRMALGOSWITCH)

Threshold of event 6A = Maximum UE transmit power Relative threshold of event 6B for BE service (ReservedU8Para0 in SET UCORRMALGOSWITCH)

For the traffic triggerred 4A, see the DCCC Based on Traffic Volume section in DCCC Feature Parameter Description.

3.9 CPC and EFACH State Transition

This section describes the new functions of state transition introduced in HSPA+.

HSPA+ requires two new states: CELL_DCH (CPC) and enhanced CELL_FACH. The CELL_DCH (CPC) state corresponds to the CELL_DCH state with continuous packet connectivity (CPC) activated, and the enhanced CELL_FACH state corresponds to the CELL_FACH state with enhanced CELL_FACH operation activated.

Figure 3-3 shows the new types of state transitions introduced in HSPA+.

WCDMA RAN




3-8

These state transitions are triggered by event 4A or 4B. Several new parameters are introduced for these state transitions, compared with state transitions between CELL_DCH and CELL_FACH.

The only impact of the following new state transitions is that new timers to trigger event 4B are introduced.

Type New Timer

RtCpc2EFachStateTransTimer: real-time service state transition timer (CPC_HSPA to E_FACH)

The only impact of the following new state transitions is that new timers and thresholds to trigger event 4A are introduced.

Type New Timer and Event 4A Threshold

F2CPC The new thresholds are as follows:

BeF2CpcHTvmThd: event 4A threshold for BE service state transition (F/RACH to CPC_HS-DSCH)

EFACH2CPC The new thresholds are as follows:

BeEFach2CpcTvmThd: event 4A threshold for BE service state transition (E_FACH to CPC_HS-DSCH)

RtEFach2CpcTvmThd: event 4A threshold for PS real-time service state transition (E_FACH to CPC_HSPA)


BeEFach2CpcTvmTimeToTrig: event 4A trigger time for BE service state transition (E_FACH to CPC_HS-DSCH)

RtEFach2CpcTvmTimeToTrig: event 4A trigger time for real-time service state transition (E_FACH to CPC_HSPA)

The function of the state transitions between enhanced CELL_FACH and CELL_PCH is the same as that of the state transitions between CELL_FACH and CELL_PCH.

3.10 Always Online

When the RNC detects that a UE performing a PS service has no data to transmit, the RNC sends a request to the CN for a service connection release. The CN initiates a release procedure, requesting the RNC to release the corresponding radio resources. The CN, however, reserves the Packet Data Protocol (PDP) context for this PS service of the UE. When the UE reinitiates the service of this PDP context, it does not need to apply for the PDP context again. Therefore, the UE in the PS domain is always online.

For each PS RAB, two Packet Data Convergence Protocol (PDCP) timers, namely T1 and T2, are available. Service connection release when a UE has no data to transmit is implemented based on these two timers. The values of T1 and T2 for different services are set by the parameters listed in Table 3-5.

SET UPSINACTTIMER is used to set the PS inactivity timers (RNC-level). If inactivity detection is not required for a particular service, set T1 and T2 to 0.

The service connection release procedure is as follows:

1. When the PDCP entity of a service is set up, timer T1 is started.

2. If the PDCP entity still detects that there is no UL or DL data packet when the T1 timer expires, the PDCP entity sends a service connection release request to the RRC layer and starts the T2 timer.

3. If the CN does not initiate the service connection release, the PDCP entity continues to detect data packets. If the PDCP entity still detects that there is no UL or DL data packet when the T2 timer expires, the PDCP entity sends a service connection release request to the RRC layer.

If there is only one RAB for the UE in the PS domain, the RNC sends an IU RELEASE REQUEST message to the CN.

If there is more than one RAB for the UE in the PS domain, the RNC sends a RAB RELEASE REQUEST message to the CN.

The two messages indicate the release causes in the User Inactivity IE.

4. Upon receiving the message, the CN initiates the release procedure. At the same time, the CN reserves the PDP context for the service. When the UE reinitiates the service of this PDP context, it does not have to apply for the PDP context again.

The service connection release request from the PDCP entity may not be processed in time because the associated processor in the RNC is busy.

3.11 PCH Blacklist

Huawei provides the PCH blacklist function to address the compatibility issue of certain types of UEs in CELL_PCH or URA_PCH state. A PCH blacklist consists of type allocation codes (TACs) of international mobile equipment identities (IMEIs). Operators add TACs of certain UEs to the PCH blacklist. The RNC determines whether the TAC of an IMEI carried in the UE-reported Identity Request message is on the PCH blacklist.

To add a TAC of a certain UE to the PCH blacklist, an operator needs to set the TAC_FUNC parameter to

Fast_Dormancy and select RSVDBIT1_BIT4 of the PROCESSSWITCH parameter, set the FastDormancy parameter to ON, and then run the ADD UIMEITAC command to add the TAC to the TAC text box.

When a UE is to transit from the CELL_DCH or CELL_FACH state to the CELL_PCH or URA_PCH state, the RNC determines whether the UE's TAC is on the PCH blacklist. If so, the RNC forbids the state transition for the UE and directly releases the RRC connection with the UE.

An IMEI consists of 14 decimal digits plus a check digit. It includes 8-digit TAC, 6-digit serial number (SNR), and 1-digit spare digit.

TAC identifies an authenticated device type.

SNR defines serial number of the UE.

The structure of an IMEI is specified in 3GPP TS 23.003. Following is the composition of an IMEI:

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