Abstract: A communication method and a communication apparatus are disclosed. A control network element receives first information from a user equipment (UE), where the first information includes multi-3GPP access request indication information or change indication information. The control network element determines, based on the first information, whether to allow the UE to establish a multi-3GPP access session. The multi-3GPP access request indication information indicates that the UE requests to establish the multi-3GPP access session, and the change indication information indicates that the UE allows the control network element to change from establishing a dual access session or a single access session to establishing the multi-3GPP access session. In this way, the control network element determines whether the UE can support a plurality of 3GPP connections at the same time, so that the UE can establish the multi-3GPP access session of new radio (NR) and long term evolution (LTE).

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: 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.
