The present invention discloses a method, apparatus and system for multicast transmission of a multimedia broadcast service, the field of communications. Said method comprising: a first base station transmits user equipment in the first base station to a gateway coverage area to receive multimedia broadcast multicast service MBMS service identifier; receiving said first base station to the user of the gateway sends device to receive the MBMS data packet and the synchronization control packet a first multicast channel, wherein the first multicast channel to a multicast channel to the user equipment receiving an MBMS located. The present invention is transmitted by a first base station to a gateway MBMS service identifier of the user equipment to be received, so that the gateway is no longer sent to the first base station unnecessary MBMS data packet, the amount of data transferred to the first base station gateway, reducing load transmission link.
