摘要： This application provides a communication method, a UP device, and a CP device, and pertains to the field of communications technologies. In the method, the UP device reports interface information to the CP device by using PFCP. Specifically, the UP device carries the interface information in a PFCP message, and transmits the PFCP message to the CP device. The CP device can obtain the interface information of the UP device from the PFCP message, which ensures that the CP device can sense the interface information of the UP device. Therefore, limitation on functions caused by insufficiency of interface information obtained by the CP device is resolved to some extent, helping the CP device implement various functions by using the interface information of the UP device.

摘要： Embodiments of the present invention provide an address assignment method, a device, and a system. The method is applicable to a network having a broadband remote access server BRAS, where the BRAS is set with carrier grade net address translation CGN, the method including: detecting, by the BRAS, that the locally set CGN fails; receiving, by the BRAS, an access request sent by a terminal; and assigning, by the BRAS, a public IP address to the terminal. In the embodiments of the present invention, when the CGN fails, terminal traffic transfer is not required, thereby shortening terminal service recovery time when the CGN of the BRAS fails, and lowering costs.

摘要： This application discloses a method and an apparatus for accessing a gateway, and pertains to the field of communications technologies. In this application, an SLA level may be obtained based on user information of a terminal, and further a UP device corresponding to the terminal is determined based on the SLA level of the terminal. In this way, terminals with different SLA levels may be allocated to different UP devices for bearing, so that a specific terminal may access a specified UP device. This resolves a problem in a related technology that a terminal relatively randomly accesses a UP device. In addition, because an SLA level may be used to indicate a level of quality of service of a terminal, after terminals with different SLA levels access different UP devices, differentiated services may be provided on the different UP devices. Therefore, user requirements are met, and revenues are increased.

摘要： This application discloses a BRAS system-based packet encapsulation method and apparatus, and pertains to the field of communications technologies. The method includes: obtaining user access information corresponding to a user access protocol packet when receiving the user access protocol packet; and performing VXLAN GPE encapsulation on the user access protocol packet based on the user access information, where a value of an encapsulation protocol field of a VXLAN GPE header in a VXLAN GPE encapsulation structure is a preset value, the preset value is used to indicate that the encapsulation structure includes a user information header that is used to store the user access information, the user information header is located immediately after the VXLAN GPE header, and a quantity of bytes occupied by the user information header is less than or equal to 12. In this application, the foregoing encapsulation structure is used to encapsulate a packet, and an encapsulated packet has backward compatibility. In addition, because the quantity of bytes occupied by the user information header is less than a quantity of bytes occupied by an NSH that carries the user access information, encapsulation overheads are saved.

摘要： This application relates to message sending and receiving methods and apparatuses, and a communication system. A control plane CP device in a communication system in which a CP and a user plane UP are separated generates a first message, where the first message includes route information and a control indication for the route information, and the route information is associated with a UP device. The CP device sends the first message to the UP device, so that the UP device updates the route information based on the control indication, where the first message is a packet forwarding control protocol PFCP message. Based on the technical solutions provided herein, interaction on routing control between the CP device and the UP device in a communication system architecture in which a CP and a UP are separated may be implemented.

摘要： This application discloses a communication method, and relates to the communications field. In the method, a fixed mobile interworking function FMIF receives an access request message that carries first authentication information of a fixed network device and that is sent by a broadband network gateway BNG, where the first authentication information is generated by the BNG based on a dial-up packet sent by the fixed network device, and the first authentication information includes an identifier of the fixed network device. The FMIF encapsulates the first authentication message in a message format supported by a control plane interface between the FMIF and a core network device, to obtain a second authentication message; and the FMIF sends the second authentication message to the core network device through the control plane interface. The core network device performs authentication on the fixed network device based on the second authentication message. A communications network version to which the core network device belongs is a 5G communications network or a communications network later than a 5G communications network.
