Abstract: A session management method and an apparatus, where the method includes: obtaining, by a session management function (SMF), a point-to-point protocol over Ethernet (PPPoE) message from a user equipment; assigning a PPPoE session identifier and/or an Internet Protocol (IP) address to the user equipment; and sending, by the SMF, the assigned PPPoE session identifier and/or IP address to the user equipment, to establish a PPPoE connection between the user equipment and a network side device. The method is performed after a packet data unit (PDU) session is successfully established. The SMF sends the PPPoE session identifier and/or the IP address to the user equipment. In this case, the user equipment can store a correspondence between the established PDU session and a PPPoE session, such that the user equipment accesses a 5G core network (CN) through a fixed network.

Abstract: A session management network element determines whether a first communication apparatus and a second communication apparatus have a redundancy functionality, receives a session establishment request message from a first terminal device, to request to establish a first session between the first terminal device and a data network. When both the first communication apparatus and the second communication apparatus have the redundancy functionality, and the first session is a redundant session, selects a first user plane function network element to establish the first session, where the second user plane function network element is configured to establish a second session, the first session is a redundant session of the second session, and the first session and the second session are for communication between the first communication apparatus and the second communication apparatus.

Abstract: Embodiments of the present disclosure disclose a session management method and an apparatus. The technology is specifically related to sending, by user equipment, a NAS message to an AGF, where the NAS message includes a PDU session establishment request message used to request to establish a PDU session, receiving, by the user equipment, a PDU session establishment accept message returned by a network side device, and establishing, by the user equipment, an access session with the AGF, where the access session is an access session related to the PDU session. The user equipment sends the NAS message to establish the PDU session, and establishes the access session with the AGF. Because the access session is related to the PDU session, the user equipment can map the PDU session to the access session, so that the user equipment accesses a 5G CN through a fixed network.
