a storage unit, for storing instructions of:
transmitting a first resume request message with a first resume identity for requesting a resume of the RRC connection to a first cell of a network;
receiving a resume reject message from the first cell of the network;
determining the first resume identity and at least one radio resource corresponding to the first resume identity are valid and keeping the first resume identity and the at least one radio resource, if the resume reject message comprises an indicator; and
determining the first resume identity and the at least one radio resource are invalid and releasing the first resume identity and the at least one radio resource, if the resume reject message does not comprise the indicator; and
a processing circuit, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
