Abstract: In a session management method, when a first access and mobility management function (AMF) network element serving a terminal becomes unavailable, a service management function (SMF) network element obtains a pool identifier of an AMF pool that includes the first AMF, and queries a network repository function (NRF) entity to obtain the address or identifier of a second AMF in the same AMF pool. The SMF then triggers the second AMF network element to obtain a context of the terminal from a unstructured data storage function (UDSF) entity.

Abstract: Example methods, devices, and apparatuses are discussed. An example method includes determining that a condition associated with triggering a registration procedure is satisfied. The condition comprises that a second tracking area (TA) supports a first slice. The second TA belongs to a current registration area (RA) of the terminal device. The first slice is rejected in the current RA, wherein the terminal device is in the second TA. The example method further includes,n response to the determination, sending a second registration request message to a core network device. The second registration request message requests to access the first slice. The second registration request message comprises information about the first slice.

Abstract: The present disclosure relates to network slice access control methods. One example method includes receiving, by an access and mobility management function network element, first information from a session management function network element, where the first information is associated with an authentication failure of a network slice, and sending, by the access and mobility management function network element, second information to a terminal device based on the first information, where the second information is used to reject access of the terminal device to the network slice.
