METHOD AND SYSTEM FOR SUPPORTING SEAMLESS HANDOVER USING MULTIPLE WIRELESS INTERFACE IN MOBILE TERMINAL

摘要

A mobility supporting system and a seamless mobility supporting method using a wireless multi-interface in the system are provided to support fast handover without requesting changing or adding of a function in an AR(Access Router). A mobile terminal(10) searches connection points connected to each interface to determine an optimum connection point, makes a second layer agreement and configures an Internet protocol address to the optimum connection point, requests generation of a standby tunnel and an active tunnel for communication from an interface of the optimum connection point and generates the standby and active tunnels according to a response, and allocates binding information according to binding update. An xGMIP mobility server(30) transmits a response to the request for generating the standby and active tunnels received from the mobile terminal, allocates the binding information according to the binding update request, and transmits the binding information to the mobile terminal.
