MOBILITY MANAGEMENT METHOD AND SYSTEM FOR MULTICAST AND BROADCAST SERVICES

摘要

A system is disclosed for performing a mobile station handover while continuing a multicast and broadcast service (MCBCS). The system includes a transceiver module transmitting from the mobile station multicast and broadcast service (MBS) zone criteria, including a list of one or more potential target base stations, to a serving base station, if a target base station is not in the same MBS zone as the serving base station. A handover request is made to one or more of the potential target base stations from the serving base station, determined based on the MBS zone criteria, where the MBS zone criteria includes an MCBCS continuity policy of the mobile station. A target base station is then selected, from the list of one or more potential target base stations, that satisfies the MBS zone criteria, and a handover process is performed to the target base station.
