1. A communication method comprising:
requesting, by a source base station of a terminal device, first group identity information of a multimedia broadcast multicast service (MBMS) in a neighboring cell, wherein when the neighboring cell belongs to a target base station, requesting the first group identity information of the MBMS in the neighboring cell comprises:
requesting, by the source base station, group identity information of the MBMS in the neighboring cell from the target base station, wherein requesting the group identity information of the MBMS in the neighboring cell from the target base station comprises:
sending, by the source base station, request information to the target base station, wherein the request information comprises second group identity information and indicates that the second group identity information is group identity information of the MBMS in a source cell, and the source cell belongs to the source base station; and
obtaining, by the source base station in response to requesting the group identity information of the MBMS, the first group identity information indicated by the target base station, wherein obtaining the first group identity information indicated by the target base station comprises:
receiving, by the source base station, first indication information sent by the target base station, wherein the first indication information indicates that the first group identity information is same as the second group identity information; and
sending, by the source base station, the first group identity information to the terminal device, the first group identity information enabling the terminal device to receive the MBMS in the neighboring cell.
