SYSTEM AND METHOD FOR PERFORMING HANDOVER OPERATION IN BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM

摘要

A Broadband Wireless Access (BWA) communication system includes a serving BS (Base Station), SS (Subscriber Station), and a plurality of neighbor BSs adjacent to the serving BS. The SS handover method upon receiving a handover request from the SS in the BWA communication system includes the steps of: a) receiving from the serving BS information of the plurality of neighbor BSs; b) measuring CINR (Carrier to Interference and Noise Ratios)s of pilot signals transferred from the neighbor BSs upon receipt of the neighbor BSs information; c) transmitting to the serving BS a handover request signal along with pilot signal CINR information of the neighbor BSs; d) upon receipt of the handover request signal, receiving from the serving BS information of a handover enable target BS contained in the neighbor BSs; and e) performing a handover function from the serving BS to the target BS.
