Abstract: When a UE is suitable for accessing a second core network, an access and mobility management function (AMF) in a first core network indicates to a radio access network (RAN) to perform rerouting and includes indication information in a rerouting request message. The indication information is used to determine the second core network, so that the UE can access the second core network via a target AMF in the second core network.

Abstract: An apparatus includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the apparatus to insert an uplink classifier user plane function network element at a home location. The uplink classifier user plane function network element is configured to offload a service flow of a terminal device. The apparatus is also caused to, in response to determining the terminal device moved to a visited location, send an address of the uplink classifier user plane function network element to an intermediate user plane function network element at the visited location to establish a tunnel between the intermediate user plane function network element and the uplink classifier user plane function network element.

Abstract: This application discloses an access control method and an apparatus, which may be used in a secondary authentication process. The method includes: An SMF receives a session establishment request sent by a terminal. The SMF determines, based on the request, to send an authentication request to a campus server. The SMF receives an authentication failure response message sent by the campus server. When the SMF determines to accept the session establishment request, the SMF sends a policy association establishment request to a PCF and receives a policy association establishment response sent by the PCF. The SMF enforces a policy for a session of the terminal according to a policy rule in the policy association establishment response. The SMF sends a session establishment response message to the terminal.
