Timers for UETimerStartStopAt expiry

T300Transmission of RRC CONNECTION REQUESTReception of RRC CONNECTION SETUPRetransmit RRC CONNECTION REQUEST if V300 =< N300, else go to Idle mode

T302Transmission of CELL UPDATE/URA UPDATEReception of CELL UPDATE CONFIRM/URA UPDATE CONFIRMRetransmit CELL UPDATE/URA UPDATE if V302 =< N302, else, go to Idle mode

T304Transmission of UE CAPABILITY INFORMATIONReception of UE CAPABILITY INFORMATION CONFIRMRetransmit UE CAPABILITY INFORMATION if V304 =< N304, else initiate a cell update procedure

T305Entering CELL_FACH or URA_PCH or CELL_PCH state. Reception of CELL UDPATE CONFIRM/URA UPDATE CONFIRM.Entering another state.Transmit CELL UPDATE if T307 is not activated and the UE detects in service area. Otherwise, if T307 is not active, start T307.

T307When the timer T305 has expired and the UE detects out of service area.When the UE detects in service area.Transit to idle mode

T308Transmission of RRC CONNECTION RELEASE COMPLETENot stoppedTransmit RRC CONNECTION RELEASE COMPLETE if V308 N300, the UE enters idle mode.

V302When initiating the procedure Cell update or URA updateUpon expiry of T302When V302 > N302 the UE enters idle mode.

V304When sending the first UE CAPABILITY INFORMATION message.Upon expiry of T304When V304 > N304 the UE initiates the Cell update procedure

V308When sending the first RRC CONNECTION RELEASE COMPLETE message in a RRC connection release procedure.Upon expiry of T308When V308 > N308 the UE stops re-transmitting the RRC CONNECTION RELEASE COMPLETE message.

V310When sending the first PUSCH CAPACITY REQUEST message in a PUSCH capacity request procedureUpon expiry of T310When V310 > N310 the UE stops re-transmitting the PUSCH CAPACITY REQUEST message.

UE Timer and Constant:The following settings can only be changed when call status is Idle . T300 RRC Conn Req Retransmit TimerThis setting determines how long the UE waits for the RRC Connection Setup after sending an RRC Connection Setup Request.T300 can be set to one of the following values: 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 3000, 4000, 6000, 8000 ms. N300 RRC Conn Req Max RetransmitsThis setting specifies the maximum number of retransmissions of the RRC Connection Request message.N300 can be set to any integer value from 0 to 7. T312 Link Establishment Timer (Idle)This setting determines how long the UE waits for an N312 "in-sync" indication from layer 1 when establishing a dedicated channel and the connection status is Idle. T312 can be set to any integer value from 1 to 15. T312 Link Establishment Timer (Connected)This setting determines how long the UE waits for an N312 "in-sync" indication from layer 1 when establishing a dedicated channel in connected status. The value 0 is not used. N312 Link Establishment In-Sync Count (Idle)This setting specifies the number of " in-syncs" required when establishing a dedicated channel when the connection status is Idle.N312 can be set to one of the following values: 1, 2, 4, 10, 20, 50, 100, 200, 400, 600, 800, 1000. N312 Link Establishment In-Sync Count (Conn.)This setting specifies the number of " in-syncs" required when establishing a dedicated channel in connected status.N312 can be set to one of the following values: 1, 2, 4, 10, 20, 50, 100, 200, 400, 600, 800, 1000. T313 Out-of-Sync Reception Timer3GPP TS 25.331 8.5.6 states that after receiving N313 consecutive "out of sync" indications from layer, the UE shall start the T313 timer. Upon receiving N315 successive "in sync" indications from layer 1, the UE shall stop and reset the T313 timer. If T313 expires, a "Radio Link failure" has occurred, and the UE shall drop the call. N313 Successive Out-Of-Sync Reception MaxN313 specifies the maximum number of successive "out of sync" received from L1.N313 can be set to one of the following integer values: 1, 2, 4, 10, 20, 50, 100, 200. N315 Successive In-Sync Reception CounterN315 specifies the maximum number of successive "in sync" received from L1 during T313 is activated.N315 can be set to one of the following integer values: 1, 2, 4, 10, 20, 50, 100, 200, 400, 600, 800, 1000. T308 RRC Conn Release Comp Retransmit TimerT308 specifies the time between the transmissions ofRRC Connection Release Completemessage. N308 RRC Conn Release Comp Max RetransmitsN308 specifies the maximum number of retransmissions of theRRC CONNECTION RELEASE COMPLETEmessage. T3212 Periodic Location Update TimerT3212 specifies how often the UE will perform the periodic location update procedure. It is signaled in SIB1.When T3212 is set to zero, the UE will regard the timer to be infinite.2015-05-11Huawei Proprietary - Restricted DistributionPage1, Total7
