METHOD AND NETWORK SYSTEM OF MULTIMEDIA BROADCAST MULTICAST SERVICE TRANSMITTING

摘要

A transmitting method of multimedia broadcast multicast service is disclosed, including: a main-entity receives MBMS data; the service data is processed by the main-entity via radio link control RLC layer and medium access control MAC layer, the data block processed by MAC layer and air interface sending time sign are sent to an accessory equipment of the main-entity; the data block received in the process adds the air interface sending time sign for forming data packet and sends to a sub-entity; the sub-entity sends the air interface sending time sign and the data block processed by MAC layer to an accessory equipment of the sub-entity; at the air interface sending time, the accessory equipment of the sub-entity and the accessory equipment of the main-entity sends the data block processed by MAC layer. Using the solution of this application, synchronous transmitting of MBMS service is realized.
