Abstract:
1. A communication system for appointing a frequency assignment (FA) mode and/or a broadcast/multicast service (BCMCS) assignment ratio in a 1xEV-DO system in order to provide a BCMCS, the communication system comprising: at least one access terminal (AT) for receiving a 1xEV-DO service or the BCMCS though the 1xEV-DO system; a base station manager (BSM) for receiving BCMCS control information containing the FA mode and/or the BCMCS assignment ratio and transmitting a received BCMCS control information to a 1xEV-DO access network controller (ANC); and an access network including a 1xEV-DO access network transceiver subsystem (ANTS) and the 1xEV-DO ANC for temporarily storing the received BCMCS control information and controlling a message being transmitted to said at least one access terminal, according to the FA mode and/or the BCMCS assignment ratio contained in the BCMCS control information; wherein the 1xEV-DO ANC is configure for assigning a specific 1xEV-DO FA, from among 1xEV-DO FAs available for the 1xEV-DO service, to the BCMCS according to each access network area in the 1xEV-DO system; the FA mode includes a dedicated BCMCS mode where the specific 1xEV-DO FA is allocated exclusively for the BCMCS, and a mixed BCMCS mode where the specific 1xEV-DO FA is allocated to both the BCMCS and the 1xEV-DO service; and in the mixed BCMCS mode, the 1xEV-DO ANC is configured for controlling a ratio of (i) a first portion of frequency capacity of the specific 1xEV-DO FA allocated to the BCMCS to (ii) a second portion of frequency capacity of the specific 1xEV-DO FA allocated to the 1xEV-DO in accordance with the BCMCS assignment ratio.
