Abstract: The present invention discloses a method and device for maintaining service continuity. The method for maintaining service continuity includes: receiving, by a base station, a first notification, which is sent by an MCE, for stopping scheduling of an MBMS service; and notifying, by the base station, user equipment of MBMS service scheduling stop information, and continuing to schedule the MBMS service. In this way, a service interruption time that is caused when UE receives a service after an MCE stops scheduling of the service can be effectively reduced.
