Broadcast communication system and broadcast communication method

摘要

A broadcast communication system comprises a transmitting terminal which is effective to transmit broadcast data and a start time of the broadcast data. A first message processing device receives the broadcast data and the start data from the transmitting terminal. The first message processing device transmits the broadcast data based on a schedule and the start time to a second message processing device. The second message processing device receives the broadcast data and the start time from the first message processing device and generates executable broadcast traffic information based on prior traffic information and based on the start time. The second message processing device further selectively conveys the broadcast data to one of a plurality of receiving terminals. The second message processing device further forwards the executable broadcast traffic information to the first message processing device. The first message processing device produces the schedule of the broadcast data based on the executable broadcast traffic information.
