1. A multimedia broadcast multicast service (MBMS) transmission method, comprising:
determining, by a core network device, a target terminal which is interested in a target MBMS;
determining, by the core network device, a cell associated with the target terminal;
sending, by the core network device, first information to an access network device to which the cell belongs, wherein the first information is used to trigger the access network device to confirm whether the target MBMS needs to be received; and
establishing, by the core network device, a broadcast connection with the access network device for the target MBMS if second information from the access network device or the target terminal is received, wherein the second information is used to indicate the access network device needs to receive the target MBMS.
