Abstract: 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.

Abstract: 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.

Abstract: A method and user equipment are provided. The method includes initiating a circuit-switched (CS) connection establishment procedure by transmitting a connection management (CM) service request message to a core network (CN). Mobility management (MM) connection establishment is aborted in response to failing to receive a CM service acceptance message within a time period. In response to subsequently receiving a CM service acceptance message after aborting the MM connection establishment, a circuit-switched (CS) signaling connection release action is performed.

Abstract: A method implemented by a processor included in a mobile terminal which is configured to communicate with a communication network, including receiving from a network a first location identifier value in broadcast system information, detecting at least one mismatch between the first location identifier value and a second location identifier value, the second location identifier value included in a location update accept message received from the network, incrementing a value of a counter based on the detected at least one mismatch, determining that the value of the counter reaches a threshold, the threshold being a maximum number of the detected at least one mismatch between the first location identifier value and the second location identifier value, and updating the first location identifier value in a Subscriber Identity Module (SIM) may be provided.
