Abstract
A cellular network system and a method for realizing broadcast communication and data communication utilize a cellular network to carry out video data broadcast and data communication with terminals. The cellular network system includes a central control node and base stations. The central control node generates control information to control the base stations to broadcast video broadcast data to the terminals during the time slot for video data broadcast, and said control information includes frequency allocation information and time slot allocation information. With the cellular network system and method thereof for realizing video broadcast and data communication in the cellular network, video broadcast and data communication are incorporated in the sectorized cellular network while avoiding a lowered efficiency of frequency spectrum use during video broadcasting due to sectorization.
