APPARATUS AND METHOD FOR EXCUTING PARTIAL HANDOVER IN BROADBAND WIRELESS COMMUNICATION SYSTEM

An apparatus and a method for performing partial handover in a broadband wireless communication system are provided to improve the communication quality of a terminal located in a cell boundary and increase the flexibility of resource utilization. An active set management unit(527) manages resource situation of adjacent base stations and reception signal strength threshold value information of each service. If a reception signal strength received from a serving base station is lower than a certain threshold value, a message generator(531) generates a connection request message for connecting the first service corresponding to the certain threshold value via an adjacent base station. A service connection controller(529) controls to connect the first service via the adjacent base station and connect the second service via the serving base station. The active set management unit updates the resource situation and the reception signal strength threshold value information of each service according to a message broadcast from the adjacent base station.
