Abstract
A communication device for handling a user equipment (UE) access stratum (AS) context comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise establishing a radio resource control (RRC) connection with a network; receiving the UE AS context from the network; receiving a RRCConnectionRelease message configuring the communication device to suspend the RRC connection and enter a RRC_IDLE state; storing the UE AS context, when receiving the RRCConnectionRelease message; restoring the UE AS context, resuming a signalling radio bearer 1 (SRB1) and transmitting a RRCConnectionResumeRequest message, when initiating a RRC connection resume procedure; receiving a RRCConnectionSetup message or a RRCConnectionReject message in response to the RRCConnectionResumeRequest message; and releasing the UE AS context and the SRB1 in response to the RRCConnectionSetup message or the RRCConnectionReject message.
