Abstract:
1. A cellular network system comprising: a central control node connected to a plurality of base stations, for generating control information including operating frequency band and operating time, which are allocated to respective sectors covered by respective base stations in the network and used for broadcast communication and data communication, respectively, and sending said control information to said respective base stations; the plurality of base stations for obtaining video broadcast data and, based on said control information, controlling its covered sectors to send the video broadcast data to said terminals via wireless channels within the operating frequency band and operating time allocated for the broadcast communication and performing data communication with said terminals within the operating frequency band and operating time allocated for the data communication; and wherein the operating frequency band and operating time allocated for the broadcast communication for all the sectors covered by all of the plurality of base stations in the cellular network are the same, while the operating frequency bands allocated for the data communication are allocated to the plurality of base stations in the cellular network according to a multiplexing factor, and each sector is allocated with an associated operating frequency band based on a number of sectors covered by each base station, wherein each of the plurality of base stations transmits a super frame to its covered sectors, the super frame constituted by the video broadcast data and the data communication data, where the video broadcast is assigned to the operating frequency band and the operating time slots allocated thereto, while the data communication data is assigned to the time slots allocated thereto and to the respective operating frequency bands allocated to a sector to which the data communication data is destined.
