  • Publication number: 20220116305
    Abstract: 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.

  • Publication number: 20200119941
    Abstract: 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 when receiving a user access protocol packet, performing VXLAN GPE encapsulation on the user access protocol packet based on the user access information, the encapsulation structure includes a user information header that is used to store the user access information, 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.
