APPARATUS AND METHOD FOR SUPPORTING VERTICAL HANDOVER IN WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus and a method for supporting handover between heterogeneous networks in a wireless communication system are provided to configure an information server applicable to MIH(Media Independent Handover) standards. An event module(240) determines whether it is necessary to update network information about at least one access network. A generating module(250) generates one or more information acquisition request packets requesting network information of one or more access networks. A communications module(210) transmits one or more information acquisition request packets to one or more access networks. A DB module(260) stores information included in an information acquisition response packet received from one or more access networks.
