A METHOD OF HIERARCHICAL TRANSMISSION FOR MOBILE MULTIMEDIA BROADCAST NETWORK

摘要

A method of hierarchical transmission for mobile multimedia broadcast network is disclosed, firstly, dividing the entire mobile multimedia broadcast system into multi-level network structure, configuring separate network resource for each network in each level network. Secondly, after the traffic of the upper level network is data stream multiplexed, it will be sent directly to all the terminals in this level network cover area via the transmitter of this level network, or sent to the corresponding receivers via the transmitters of the distributing network and the lower level network. Finally, the receiver receives signals from different networks selectively according to the network range in which it resides. The method according to the present invention solves the bottleneck problem that the permit of the network operator must be obtained when a service needs to be sent across different areas, realizes the national network really, and realizes the national broadcast service and the combination of the national network operating and the local network operating better.
