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.
