Abstract: Methods and apparatus for notifying a mobile station (MS) of service flow parameters supported by neighbor base stations, such that the MS may select a suitable neighbor base station (BS) candidate (i.e., a target BS) for performing a handover are provided. The notification may occur 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 may be maintained as an MS is handed over from one BS to another.
