Abstract: A method, device and system are used for transmitting a Multimedia Broadcast Multicast Service (MBMS). The method includes sending, by a first base station, a service identifier of a MBMS that needs to be received by a user equipment in a coverage area of the first base station to a gateway. The first base station receives a data packet of the MBMS and a synchronization control packet on a first multicast channel which are sent by the gateway. The first multicast channel is a multicast channel where the MBMS is located.
