Method and system for providing status information for broadcast/multicast service in a mobile communication system
First Claim
1. A method for providing a Broadcast/Multicast Service (BCMCS) from a base station to a mobile station in a mobile communication system including a BCMCS content server for storing a plurality of BCMCS contents, a BCMCS controller connected to the BCMCS content server, and at least one mobile station located in an area occupied by the base station, the mobile station being connected to the BCMCS controller and a packet data service node (PDSN) via the base station, the method comprising the steps of:
- receiving a BCMCS registration message from the mobile station; and
transmitting a broadcast order message in response to the BCMCS registration message;
wherein the BCMCS registration message includes a BCMCS flow identifier (ID) indicating at least one BCMCS content, and the broadcast order message includes BCMCS unavailable information indicating that BCMCS content corresponding to the BCMCS flow ID is unavailable.

Abstract
In response to a BCMCS service request from a mobile station, a base station separately informs the mobile station whether the requested BCMCS service is available. Thus, the base station can include only broadcast channel information necessary for actual broadcast in a broadcasting overhead message, and if the BCMCS service is stopped or unavailable, the base station can order the mobile station to interrupt the BCMCS service, thereby reducing the load on system resources.
