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

摘要

A method and an apparatus for supporting seamless mobility using a multi-radio interface in a mobile terminal are provided to support fast handover without requesting changing or adding a function in an AR(Access Router). A main controller(110) initializes a multi-radio interface in standby state, generates active and standby tunnels and switches the active tunnel into the standby tunnel in an initiated state. A searching unit(140) periodically searches connection points connected to each interface. An interface handover processing unit(120) selects an optimum connection point from among the searched connection points, determines active and standby interfaces according to a state of each interface when the initiated state is confirmed, and requests the main controller to generate the active and standby tunnels and switch the tunnels according to a state of a radio link with respect to the determined active and standby interfaces. An interface state selection unit(124) includes functions related to an active tunnel creation request, a standby tunnel creation request and a tunnel switchover request.
