Abstract: Embodiments of the present disclosure provide a session management method and an apparatus. The method includes: receiving, by a first session management SM entity, first session context information from a second SM entity; further, generating, by the first SM entity, second session context information based on the first session context information; and sending the second session context information to a terminal. As can be learned, a session in a tracking area update procedure of the terminal is updated in a scenario in which an MM entity and an SM entity are separated.

Abstract: This application provides a handover method, including: determining, by a mobility management (MM) network element, to hand over a session management (SM) for a user equipment (UE), and selecting target SM network element; and triggering, by the mobility management network element, a process of setting up a channel by the target SM network element, where the channel includes a user plane data channel between a target user plane (UP) function entity and a target base station. Therefore, it is possible to hand over a network in which a control plane (CP) is separated from a UP and an MM and an SM in the CP are separated from each other.

Abstract: Embodiments of the present invention provide a method and a device for associating a user with a group. The method includes: receiving, by a first communications device, a first association request sent by a second communications device, where the first association request includes an identifier of an MCPTT user and identifiers of N MCPTT groups, and N is a positive integer; associating the MCPTT user with M MCPTT groups of the N MCPTT groups according to association subscription information of the MCPTT user; and sending a first association response to the second communications device, where the first association response is used to indicate that the MCPTT user is successfully associated with the M MCPTT groups of the N MCPTT groups, 1≤M≤N, and M is an integer. In this way, the MCPTT user is associated with the M MCPTT groups that the MCPTT user is interested in.
