METHODS AND SYSTEMS FOR SELECTING TARGET BS WITH BEST SERVICE SUPPORTED IN WIMAX HANDOVER

摘要

PROBLEM TO BE SOLVED: To provide methods and apparatus for notifying a mobile station (MS) of service flow parameters supported by neighbor base stations (BSs), so that the MS may select a suitable neighbor BS candidate (i.e., a target BS) for performing a handover.SOLUTION: The notification may be performed via handover messages, such as a BS Handover Request (MOB_BSHO-REQ) message or a BS Handover Response (MOB_BSHO-RSP) message, with a Service Level Supported field added, indicating the service flow parameters supported by the neighbor BSs. In this manner, service quality levels of data exchanges are maintained as an MS is handed over from one BS to another.
