Information acquiring method and base station
An information acquiring method and a base station. The method comprises: receiving by a target base station reception status information of a multimedia broadcast multicast service of user equipment reported by a source base station when the user equipment is handed over between cells; wherein the reception status information comprises information indicating that the user equipment is receiving a multimedia broadcast multicast service, or information indicating that the user equipment finishes receiving a multimedia broadcast multicast service. With the embodiments of the present invention, the source base station of the user equipment notifies the target base station of reception status information of multimedia broadcast multicast service of the user equipment when the user equipment is handed over between cells, thereby guaranteeing the continuity of the MBMS of the user equipment.
1. A method used in a communication system, comprising:
transmitting, from a user equipment to a source base station before the UE performs a handover from the source base station to a target base station, information indicating that the user equipment is receiving a multimedia broadcast multicast service and a carrier frequency carrying the multimedia broadcast multicast service which the user equipment is receiving,
sending, from the source base station to a target base station, reception status information of the multimedia broadcast multicast service of the user equipment based on the information transmitted from the user equipment to the source base station, and
providing the user equipment with a corresponding multimedia broadcast multicast service by the target base station in accordance with the reception status information of the multimedia broadcast multicast service of user equipment sent from the source base station.
2. A method used in a user equipment, comprising:
receiving data of a multimedia broadcast multicast service; and transmitting to a source base station before the user equipment is handed over from the source base station to a target base station a reception status information of a multimedia broadcast multicast service of the user equipment which indicates a carrier frequency carrying the multimedia broadcast multicast service which the user equipment is receiving;
wherein the target base station is notified of the information when the user equipment is handed over from the source base station to the target base station; and
receiving a corresponding multimedia broadcast multicast service from the target base station in accordance with the reception status information of the multimedia broadcast multicast service of user equipment sent from the source base station.
