ESTABLISHING NETWORK ADDRESS OF MOBILE TERMINAL IN MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to establishing a network address of a mobile terminal in a mobile communication system when the mobile terminal is handed over from one network to another. Preferably, the present invention establishes a unified interface to an upper layer of the mobile terminal for managing messages to and from at least one of a homogeneous network and a heterogeneous network, performs handover of the mobile terminal to at least one of a homogeneous network and a heterogeneous network, receives in the upper layer a request from the unified interface for establishing a network address of the mobile terminal for the at least one of a homogeneous network and a heterogeneous network for communicating data, and establishes the network address for the at least one of a homogeneous network and a heterogeneous network.
