A system and method for fast network re-entry in a broadband wireless access communication system. A mobile station transmits a first message requiring fast network re-entry to a base station and performs the fast network re-entry together with the base station when receiving a second message approving the fast network re-entry from the base station. The base station receives the first message, authenticates the first message using final session information of the mobile station that is previously stored in the base station, transmits the second message to the mobile station when succeeding in authentication of the first message, and performs the fast network re-entry together with the mobile station.

An apparatus and method for seamlessly providing voice and data services to a user through an access terminal in a mobile communication system including a heterogeneous service & mobility gateway (HSMG) for an interworking service between a circuit network and a packet network, and various access networks overlapping each other. The access terminal notifies the HSMG that a voice call is received, if the access terminal that accessed a packet network receives a voice call. The HSMG sends a direction request to a circuit network upon receiving the notification indicating that the voice call is received. The access terminal directs to the circuit network and registers a new location upon receiving the direction request. The HSMG sets up an incoming voice call to the access terminal after the registration of a new location.

A wireless packet data system efficiently manages a location of a packet call in a radio environment. A mobile station transmits a location registration message to a target BSC when moving to the target BSC adjacent to a source BSC. Upon receipt of the location registration message, the target BSC transmits a location update message for updating a location of the mobile station to a centralized database. Upon receipt of the location update message, the centralized database updates dormant state information for the mobile station to connect the target BSC to the source BSC. The centralized database transmits a location update result message indicating complete update of the dormant state information to the target BSC.
