UE identified by Initial UE identity IE in RRC connection request and RRC connection setup message but i don't know how RNC distinguish UEs when received RRC connection setup complete message.
Could you please explain this case?
Is DRX will by default present in UE?or will it be assigned by eNB? If it is assigned by eNB,then in which message does it send to UE,in RRC setup or RRC reconfiguration or SIB2 message?
