摘要： 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.

摘要： In a method for network communications, a session management network element receives an identifier of a session of a terminal device, an identifier of a port corresponding to the session, and a processing policy of a data flow for the port. The session management network element determines, according to the identifier of the port, a type of a first device corresponding to the port. The session management network element then sends, according to the determined type of the first device, processing policy information to the first device. The processing policy information comprises the identifier of the port and the processing policy of the data flow.

摘要： A communication method implemented by a terminal device includes detecting whether a clock source declaration from a user plane network element is received within a first duration, and when the terminal device does not receive the clock source declaration from the user plane network element within the first duration, sending a clock source declaration from a remote device to the user plane network element. According to the method, when the terminal device does not receive the clock source declaration from the user plane network element within the first duration, this indicates that the user plane network element cannot receive a clock source declaration from another terminal device. Accordingly, the clock source declaration of the remote device is sent to the user plane network element.

摘要： 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.
