摘要： A method for handling a service connection in a wireless communication system, including detecting, by a User Equipment (UE), a Mobility Management (MM) service state of the UE is set to ATTEMPTING TO UPDATE, receiving, by the UE, a valid Temporary Mobile Subscriber Identity (TMSI) in a TMSI reallocation procedure from a base station via a Radio Resource Control (RRC) connection, changing, by the UE, the MM service state to a NORMAL SERVICE state in response to the receiving a valid TMSI and the detecting a MM service state, and sending, by the UE, a paging response message to the base station in response to the changing the MM service state and a paging indication message received from the base station to establish the service connection, the paging indication message including the valid TMSI.

摘要： A method implemented in a User Equipment (UE) for service recovery in a wireless communication network includes establishing a first Radio Resource Control (RRC) connection with a Public Land Mobile Network (PLMN) via a first cell corresponding to a network, transmitting, to the network, a Protocol Data Unit (PDU) establishment request for a service from the first cell using the first RRC connection, receiving, from the network in response to the PDU establishment request, a PDU establishment failure message based on at least location information of the UE, performing a local deregistration with the first cell based on the PDU establishment failure message, and establishing a second RRC connection with the PLMN via a second cell corresponding to the network.
