    Abstract: Embodiments of the present invention disclose a handover method and a related user equipment and system, which are used for handover judgment in a CoMP handover scenario. The method according to an embodiment of the present invention includes: obtaining a first reference signal parameter Mn of a target node in a macro neighboring cell and second reference signal parameters Mp corresponding to multiple nodes in a macro serving cell, where the macro serving cell is a cell serving a user equipment UE and the macro neighboring cell is a cell adjacent to the macro serving cell; selecting a preferred Mp that meets a predefined requirement from the Mps corresponding to the multiple nodes; and triggering a handover procedure if the preferred Mp and the Mn meet a preset handover condition. By implementing the solutions in the present invention, throughput of a communications system after a UE handover can be increased.

    Abstract: 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. The method includes sending a handover request instruction to a second base station. The handover request instruction includes information of a first coordinated multi-point set of a user equipment. A handover request response is received from the second base station. The handover request response includes information of a second coordinated multi-point set allocated by the second base station for the user equipment. The information of the second coordinated multi-point set sent to the user equipment.

    Abstract: The present invention provides a method including receiving, by a terminal, a switching command is large. The method includes: acquiring designated channel resource information from channel resources used by a source base station; acquiring information of a relevant base station using a designated channel resource except the source base station; sending indication signaling to the relevant base station according to the information of the relevant base station, where the indication signaling carries the designated channel resource information, the indication signaling is used to instruct the relevant base station to stop using the designated channel resource when the mobile terminal switches to a target base station; sending a switching request message to the target base station; and sending the switching command to the mobile terminal through the designated channel resource.
