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.

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: This application provides a slice information update method and an apparatus. The method includes: when determining that a network slice that was not supported by a PLMN is updated to be supported by the PLMN, sending, by a network slice selection network element, a notification message to a communications network element, where the notification message is used to indicate that the PLMN supports the network slice; and notifying, by the communications network element, a terminal that the PLMN currently supports the network slice. In this way, the corresponding terminal learns that the PLMN currently supports the network slice.

Abstract: This application is directed to a method and an apparatus for associating an application with a network slice, and a communications system. The method includes: obtaining, by a terminal, display instruction information, an identifier of a first network slice that the terminal is allowed to access, and service feature information corresponding to the first network slice. The method further includes: displaying the service feature information corresponding to the first network slice on a first display interface of the terminal based on the display instruction information, and generating a first network slice selection policy when detecting an operation of associating a first application with the first display interface. The first network slice selection policy can include a mapping relationship between the first application and the identifier of the first network slice corresponding to the first display interface.
