A communication system provides one or more of congestion information and subscriber information to a broadcast applications server when the server receives a request to start a broadcast-multicast service in a coverage area. By providing the one or more of congestion information and subscriber information to the server, the server is able to make an informed, intelligent decision concerning blocking, unblocking, downgrading, or upgrading a broadcast-multicast flow of multiple broadcast-multicast flows requested for delivery to, or currently delivered to, the coverage area via a serving base station, and/or whether to add a new broadcast-multicast flow to the broadcast-multicast flows delivered to the coverage area.
