Abstract: This application provides a session handling method, a communications apparatus, and a communications system. The session handling method includes receiving, by an intermediate session management function (SMF), a request message sent by an access and mobility management function (AMF), where the request message includes a session identifier, and the intermediate SMF is an SMF selected by the AMF when user equipment (UE) moves outside of a service area of an anchor SMF. When a session corresponding to the session identifier is a local area data network (LADN) session, rejecting, by the intermediate SMF, the session corresponding to the session identifier. According to the technical solutions provided in this application, the user equipment can no longer access a service of a LADN after moving outside of the service area of the anchor SMF, which avoids a waste of service resources of the LADN.

Abstract: A method and an apparatus for determining a protocol data unit (PDU) session service network element to control an aggregated maximum bit rate (AMBR), where the method includes receiving, by a control plane function network element, a request for establishing a first PDU session from a mobility management device, where the request for establishing the first PDU session includes a first data network name (DNN), determining, by the control plane function network element, that a same control plane function network element and a same user plane function network element need to be selected for a PDU session corresponding to the first DNN, and sending, by the control plane function network element, first indication information to the mobility management device, where the first indication information is used to indicate that a same control plane function network element needs to be selected for the PDU session corresponding to the first DNN.

Abstract: This application provides a route configuration method and an apparatus, and relates to the field of communications technologies. The method includes: After a first terminal moves out of a service scope of a UPF that currently provides a service for the first terminal, a first SMF inserts a first I-UPF into a user plane path of the first terminal, and configures, for the first I-UPF, a first routing rule corresponding to a second terminal. The first routing rule is used to send a packet whose destination address information is address information of the second terminal to a second A-UPF. Therefore, a packet whose destination address information is the address information of the second terminal can be directly forwarded by the first I-UPF to the first A-UPF, instead of being forwarded by the first I-UPF to the second A-UPF through the first A-UPF.

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 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.
