METHOD FOR HANDOVER IN A BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM

摘要

A method for handover in a BWA communication system including MSSs, a serving Base Station, neighbor BSs different from the serving BS, and sponsor nodes. The method includes the steps of: transmitting by the MSS a handover request to the serving BS when the MSS detects a need to handover; selecting by the serving BS a target sponsor node to which the MSS will perform handover, notifying the MSS that the MSS must perform the handover to the target sponsor node; and notifying the serving BS that the MSS will perform the handover to the target sponsor node when the MSS has received a notification from the serving BS that the MSS must perform the handover to the target sponsor node in response to the handover request.
