Abstract:
Methods, apparatus and media for receiving emergency broadcast information in a broadcast-multicast service of a communication system. The methods, apparatus and media include scheduling a broadcast of emergency broadcast information in designated control channel cycles for designated subscriber stations. The control channel cycles are transmitted with the designated control channel cycles including the emergency broadcast information. Subscriber stations awake according to their designated control channel cycle and receive the transmission of their designated control channel cycle on a broadcast-multicast service. The subscriber station determines if emergency broadcast information is in the control channel cycle assigned to the subscriber station and responds accordingly.
