ENB HANDOFF METHOD, X2 INTERFACE ESTABLISHMENT METHOD, ENB, USER EQUIPMENT AND SYSTEM

摘要

Embodiments of the present invention provide a base station handover method, an X2 interface setup method, a base station, a user equipment and a system, which relate to the field of communications technologies and enable a user equipment to immediately adopt a CoMP technology after completing handover, thereby raising the success ratio of the handover and the system throughput. The method includes: sending a handover request instruction to a second base station, where the handover request instruction includes information of a first coordinated multi-point set of a user equipment; receiving a handover request response from the second base station, where the handover request response includes information of a second coordinated multi-point set allocated by the second base station for the user equipment; and sending the information of the second coordinated multi-point set to the user equipment. The embodiments of the present invention are used by the user equipment to be handed over between the base stations.
