sending the handover response signaling to the multi-card user equipment;
wherein the method further comprises:
determining to not allow the multi-card user equipment to perform the handover operation in response to that a first processing priority corresponding to the to-be-transmitted service in the first communication system is not lower than a second processing priority corresponding to the to-be-transmitted service in the second communication system;
sending, to the multi-card user equipment, a response signaling indicating that the multi-card user equipment is not allowed to perform the handover operation; or
refusing to send a response signaling to the multi-card user equipment.
