SYSTEM AND METHOD FOR DETERMINING A HANDOVER AT A BASE STATION REQUEST IN A BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM

摘要

A broadband wireless access communication system in which a subscriber stati on (SS) sends a serving base station (SBS) a handover request to neighbor base stations (NBSs) having a CINR satisfying a handover condition, in response t o a handover scan request message, and performs the handover to a particular N BS that transmits a handover response. The SBS transmits the handover scan request message to the SS, sends a handover connection request to NBSs in an order determined by CINRs reported from the SS, and sends, to the SS, information on a particular NBS upon receiving a handover connection respons e with ACK information from the particular NBS. The particular NBS determines whether it can support handover of the SS, in response to the handover connection request, and sends the handover connection response with the ACK information to the SBS, if it can support handover of the SS.
