Method and system for providing a broadcast/multicast service in a wireless communication system
First Claim
1. A method for controlling a Mobile Station (MS) to receive BCMCS (Broadcast/Multicast Service) data in a mobile communication system including at least one BCMCS controllers and the MS for receiving the BCMCS data through a BSs(Base stations), comprising the steps of receiving, from a new BS, a new BCMCS zone ID that is different from a prestored old BCMCS zone ID, while receiving old BCMCS data from an old BS;
- requesting new BCMCS data to the new BS, establishing a channel with the new BS;
receiving a BCMCS information from the new BS; and
receiving the new BCMCS data from the new BS using the BCMCS information.

Abstract
A broadcast service method and system for use in wireless communication system. The broadcast service method and system for a wireless communication system according to the present invention assigns individual unique BCMCS IDs to a plurality of BCMCS controllers, such that it can recognize a changed BCMCS controller within a cell in which an MS is located, BSPM (Broadcast Service Parameter Message) effectiveness, the BCMCS conversion, etc.

11. An apparatus for providing BCMCS (Broadcast/Multicast Service) service in a mobile communication system, the apparatus comprising:
-
a MS for requesting BCMCS data from a new BS using a prestored BCMCS zone ID when a BCMCS zone ID, which is different from the prestored BCMCS zone ID, is received from the new BS while receiving the BCMCS data, and requesting BCMCS-associated information used for the BCMCS data;
at least one base station (BS), including the new bases station, for wirelessly communicating with the MS and transmitting the BCMCS zone IDs and broadcast provision information;
at least two BCMCS controllers that are connected to at least one PDSN (Packet Data Service Node), which transmits packet data service data to the at least one BS, for transmitting BCMCS-associated information for the BCMCS data requested by the MS to the MS over the connected PDSN, and containing the BCMCS zone IDs; and
a BCMCS server for providing the MS with the BCMCS data using the BCMCS-associated information and the broadcast provision information. - View Dependent Claims (12, 13)
