Abstract: This application provides an external authentication method, to implement authentication of a terminal with external subscription. The method includes: A mobility management network element obtains external authentication indication information. The mobility management network element sends a first request message to a terminal based on the external authentication indication information, where the first request message is used to request external authentication. The mobility management network element receives a first non-access stratum NAS message from the terminal. The mobility management network element sends related information of an external entity to an authentication server function network element based on the first NAS message, where the related information of the external entity is used to address the external entity, and the external entity is configured to perform authentication on the terminal. The mobility management network element receives an external authentication result from the authentication server function network element.

Abstract: A routing rule management method and a communications apparatus, where after a first user plane function network element receives, through a protocol data unit (PDU) session, a first data packet, from a terminal, whose source address is a first address, the first user plane function network element generates a first routing rule corresponding to the PDU session when determining that the first address is an unknown media access control (MAC) address, and where the first routing rule is used to forward, to the PDU session, a data packet sent to the first address. After detecting the unknown MAC address, the first user plane function network element may generate a routing rule corresponding to the unknown MAC address without involvement of a session management function network element.

Abstract: A method and an apparatus for initiating user plane path re-establishment and a communications system are disclosed. The method includes: determining, by a session management function entity based on first location information of a terminal device, a session service area to which a current session of the terminal device belongs; and after receiving second location information of the terminal device sent by a mobility management function entity, if determining that the second location information is not within the session service area, instructing the terminal device to initiate a re-establishment procedure for the current session or initiate a handover procedure. Due to introduction of the session service area, when the terminal device moves back and forth at edges of service areas of two adjacent user plane function entities, a ping-pong effect caused by frequent handover between the two user plane function entities is avoided, and user experience is improved.

Abstract: A local area network communication method, a device, and a system, to implement private communication across session management network elements for a local area network service. The method includes: determining, based on indication information of a local area network, first path information associated with a first address, where the first path information indicates routing data whose destination address is the first address to a first user plane network element, and where the first user plane network element provides access to the local area network for a terminal corresponding to the first address; and sending a first message to a second session management network element, for configuring a first routing rule on the second user plane network element, where the first routing rule includes the indication information of the local area network, the first address, and the first path information.
