Abstract: The present invention provides a communications system, a local mobile node, and a base station. The communications system includes an MME, multiple eNBs, and a local mobile node. The local mobile node receives a path handover request sent by a target eNB, and when determining, according to a path handover request message, that a local path handover needs to be performed, establishes a user data path between the local mobile node and the target eNB for UE according to the path handover request, so that user plane data is transmitted between the UE and a serving gateway by using the user data path. In this way, signaling load on the MME can be avoided, a time consumed by an entire handover procedure is shorter, and a handover failure caused in a conventional manner is avoided.

Abstract: This application provides an IAB node mobility management method and a related device. If an IAB node encounters an unpermitted area, the method provides a solution in which access of an JAB-MT is allowed but an IAB-DU is not activated. This is conducive to rapid recovery of communication after the IAB node moves out of the unpermitted area while satisfying an unpermitted area constraint. This application can support setting of an unpermitted area that is less than a cell granularity and that is related to a cell, and can also be compatible with setting of an unpermitted area that is greater than or equal to a cell granularity or that is unrelated to a cell.
