Abstract: An apparatus for the handover between heterogeneous networks and a method thereof are provided to process the handover between same networks by performing the operation of a base station within a corresponding network in an IWF. When a terminal enters a border cell between heterogeneous networks, base station information of a target network is transmitted to an IWS(Inter Working Server)(400). The IWS confirms the address of an IWF(Inter Working Function) which manages base stations of the target network(402), and then transmits terminal information required for the entry into the target network to the IWF(404). Through the terminal information, the IWF performs the handover procedure with the terminal instead of the base station.

Abstract: 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.

Abstract: An apparatus and a method for scheduling in a broadband wireless access system are provided to estimate a hereafter channel state per each user, and to give the scheduling priority to users according to the estimated channel state. A base station buffers channel information which is fed-back from terminals periodically into a specified window size(601). The base station estimates next channel state by using the average channel variation amount(603). The base station classifies the terminals into three sub groups by using the estimated channel values(605). The base station arranges the sub groups according to the priority(607). The base station classifies the terminals per each of sub groups according to the channel level(609). The base station decides the priority of each terminal by arranging the terminals according to signal delay values(611). The base station creates a resource assignment priority list according to the priority(613). The base station assigns the resource to each terminal by performing the scheduling according to the priority list(615).
