Equipment and method for activating broadcast multicast business

The invention relates to the field of radio communication and discloses a method and device for deactivating broadcast and multicast services to facilitate correct de-activation after a roaming user uses MBMS service. In the invention, BM-SC of a visited network and a home network conduct joint verification as to whether the indicator suggesting that a roaming UE leaves broadcast and multicast service is valid through the alternation of BM-SC of the visited network and BM-SC of the home network. If BM-SC of the visited network provides the broadcast and multicast services where the UE leaves,BM-SC of the visited network will notify BM-SC of the home network that a UE context of the broadcast and multicast service should be deleted before or after BM-SC of the visited network deletes the UE context of the broadcast and multicast services.
