A method and system for a roaming service in a mobile communication system are provided. The system includes an access terminal for transmitting an NAI (network access identifier) to a packet data serving node of the visited network and an AAA (authentication authorization accounting) of the home network, for transmitting subscriber profile information of the access terminal to the visited network. The packet data serving node of the visited network determines whether or not the access terminal subscribes to the roaming service on the basis of the NAI, and, when it is determined that the access terminal subscribes to the roaming service, sends a request for transmitting the subscriber profile information of the access terminal to the AAA of the home network. The packet data serving node of the visited network also provides at least one data service that the home network has provided to the subscriber, using the subscriber profile information.

An apparatus and method for connecting to one of different types of access networks in a heterogeneous network system in which the access networks overlap each other. The apparatus and method include attempting to connect to one of said one or more access networks according to a preset priority and receiving a communication service through the access network when a connection to the access network is successful; and attempting to connect to an access network having a next priority according to the preset priority when the connection to the access network is unsuccessful.

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.
摘要:
A data push service system and method using a heterogeneous network. The system transmits push data to a Hybrid Access Terminal (HAT) in a heterogeneous mobile communication system in which at least one circuit network overlaps with at least one packet network. The HAT can be connected to a circuit network or a packet network, and is registered in a new access network. The system includes a Packet Service & Mobility Gateway (PSMG) for acquiring access state and connection information of the HAT from the circuit network and the packet network, and generating an access network switching request upon receipt of an external request signal; and a Push Proxy Gateway (PPG) for acquiring access information of the HAT which will transmit the push data from the PSMG, and transmitting a request message to the PSMG.
