Abstract: A multimedia broadcast multicast communication method, an apparatus, and a system are provided. The method includes: receiving, by a base station, first indication information at a first time, where the first indication information is used to indicate that transmitting service data in a multimedia broadcast multicast service MBSFN manner is to be suspended; and sending, by the base station, second indication information to user equipment UE according to the first indication information, so that the UE suspends, at a second time according to the second indication information, receiving the service data in the MBSFN manner. The first time is earlier than the second time, and duration between the first time and the second time is less than a multicast control channel MCCH modification period. The user equipment is notified in a more timely manner to suspend transmitting the service data in the MBSFN manner.
