Abstract: This application discloses a load relocation method, apparatus, and a system. The method includes determining, by a communications network entity, a target access management entity for load relocation; and sending, to an access network entity, an identifier of an original access management entity and an identifier of the target access management entity or an address of the target access management entity with respect to the access network entity. The access network entity sends a message from a user equipment (UE) to the target access management entity based on the identifier of the original access management entity carried in the message from the UE. In the foregoing solution, signaling overheads in a load relocation process are reduced and load relocation efficiency is improved.

Abstract: A communications method, apparatus, and system to implement handover between session management network elements, where a target session management network element sends a first message to a source session management network element based on the information about the source session management network element received. After receiving the first message from the target intermediate session management network element, the source session management network element indicates, based on the first message, a source intermediate user plane network element to establish a forwarding tunnel. As such, the forwarding tunnel between the source intermediate user plane network element and a target intermediate user plane network element is established, and the source intermediate user plane network element can forward data to the target intermediate user plane network element through the forwarding tunnel.

Abstract: A communication method, a communications device, and a communications system to avoid, when an access and mobility management function (AMF) entity fails, a case in which a re-registration process of a terminal that is being served is triggered because a context of the terminal is lost. The method includes: obtaining, by a communications device, a first group identifier of a terminal group to which a first terminal served by a first mobility management entity belongs; and sending, by the communications device, a message related to the first terminal to a second mobility management entity based on the first group identifier when an exception occurs in the first mobility management entity, where the second mobility management entity is a mobility management entity in which a context of the first terminal exists.
