UE, the basic constraints that activationary time promptly is set is: activationary time is carried out " the Radio Link Synchronization Reconfiguration Commit " time of message, the one way propagation delay time of IUB interface message transfer and the processing time sum of Node B greater than sending the RL synchronized reconfiguration; And activationary time is greater than sending time, the one way propagation delay time of IUB interface message transfer and the processing time sum of UE that RB sets up " Radio Bearer Setup " message.
In the technique scheme, after SRNC had finished configuration to Node B, SRNC just sent RB to UE and sets up " Radio Bearer Setup " message with configuration UE.If SRNC has received the RB that UE returns and has set up failure " Radio Bearer Setup Failure " message that then represent the configuration failure of UE side, UE still uses original configuration.But, because having sent the RL synchronized reconfiguration to Node B, SRNC this moment carries out " Radio Link Synchronization ReconfigurationCommit " message, then the configuration of Node B can't rollback.After activationary time arrived, the configuration that Node B and UE adopt was inconsistent, and calling can't be kept.Therefore, SRNC initiates Radio Resource control (Radio Resource Control is hereinafter to be referred as RRC) to connect and discharge notice Node B and UE this is called out to be connected and is released.
In sum, prior art is owing to adopt SRNC to notify Node B to reshuffle execution earlier, again the UU interface message is sent to the technical scheme of UE, in case cause the UE reconfiguration failure, make that whole wireless connections can't rollback because the configuration of Node B side and UE side is inconsistent, must discharge RRC and connect, increase the calling cutting off rate.

DELAY, the constraints that new activation moments promptly is set is: activation moments is set up " Radio Bearer Setup " message moment, the one way transmission time length of 3 times of IUB interface message transfers and the processing time length sum of Node B processing messages greater than sending RB.
The above-mentioned constraints that new activationary time is set can reach configuration take-effective and the feasible purpose of rollback.
Alternatively; Above-mentioned SRNC sends the operation that the RL synchronized reconfiguration is prepared " RadioLink Synchronization Reconfiguration Prepare " message to Node B in the present embodiment; And above-mentioned Node B returns the operation that the RL synchronized reconfiguration is ready to complete " Radio Link SynchronizationReconfiguration Ready " message to SRNC and can carry out after SRNC is receiving the acknowledgement message of UE.The setting of activationary time so; Accordingly then will be further considered the processing time of Node B to above-mentioned " Radio LinkSynchronization Reconfiguration Prepare " message. is that the activationary time starting point is that SRNC issues the moment that RB sets up message to UE, and activationary time is contained: SRNC to UE send rlc layer that RB sets up the one-way transmission time+UE of message returns one-way transmission time+SRNC from acknowledgement message to RNC to Node B send the RL synchronized reconfiguration prepare one-way transmission time of message+Node B returns one-way transmission time+SRNC from the ready message of RL synchronized reconfiguration to SRNC to Node B send the RL synchronized reconfiguration carry out RL synchronized reconfiguration that one-way transmission time of message+Node B receives that SRNC sends prepare after the message the processing time+Node B receives the processing time after RL synchronized reconfiguration that SRNC sends is carried out message. Therefore; The length of above-mentioned activationary time greater than 5 times of IUB interface one-way transmission message time+Node B handle the RL synchronized reconfiguration prepare message the processing time+Node B handles the processing time that the RL synchronized reconfiguration is carried out message; The constraints that new activation moments promptly is set is:activation moments greater than send RB set up " Radio Bearer Setup " message constantly, the one way transmission time length of 5 times of IUB interface message transfers and the processing time length sum of Node B processing messages.
In the above-mentioned execution mode of RB control method of the present invention, because the RB control procedure needs Node B and UE to enable new configuration simultaneously, so any one among Node B and the UE can not successfully be enabled new configuration, above-mentioned RB control procedure will be failed, and under the failure scenarios following handling process can be arranged:
Situation 1:SRNC sends the RB control messages to UE, UE handles and receives this message failure, then the rlc layer of UE can not return to SRNC and receive above-mentioned RB control messages acknowledgement message, this moment, SRNC determined the flow process failure, SRNC sends RL to NODE B and reshuffles cancellation message, carry out the resource rollback of local terminal, flow process finishes;
Situation 2:SRNC sends the RB control messages to UE, UE normally receives this message, but the rrc layer of UE is handled this message failure, UE returns RB control failed message to SRNC, SRNC receives that this message determines flow process failure, SRNC sends RL to NODE B and reshuffles cancellation message, carries out the resource rollback of local terminal, and flow process finishes;
Situation 3:SRNC sends the RB control messages to UE, receive the acknowledgement message of rlc layer, send the RL reconfiguration prepare message to NODE B, received the RB control failed message that UE returns afterwards, SRNC judges whether the current moment has arrived activation moments-times One Way Delay constantly, if not to this moment then SRNC sends RL to NODE B reshuffles cancellation message, SRNC rollback local terminal resource, flow process finishes; If arrived this moment then flow process can't rollback, NODE B has started new configuration, and UE can only use old configuration, and SRNC triggered RRC and discharged flow process this moment, and this calls out call drop.
