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: A network topology discovery method, includes: A second network device receives a first LLDP packet sent by a first network device. The first LLDP packet includes first slice information, and the first slice information is used to indicate a network slice to which a first port of the first network device belongs. The second network device sends the first slice information and second slice information to a management device. The second slice information is used to indicate a network slice to which a second port of the second network device belongs.
