Handover apparatus and handover method in wireless communication system

摘要

Provided are a method and apparatus for performing handover of a terminal in a wireless communication system, the method including obtaining information on neighboring networks from a media independent handover (MIH) server by using a MIN layer if a state of a link connected to a serving network is changed; transmitting a handover initiation request message to the MIH layer of the serving network through the MIH layer; checking handover support information and tunnel state information of the neighboring networks which are received from the MIH layer of the serving network; determining a target network to which handover is performed and performing layer-2 (L2) handover with the target network, by using the handover support information; and performing layer-3 (L3) handover with the target network by using the tunnel state information.
