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.

Abstract: A BRAS system-based packet encapsulation method includes obtaining user access information when receiving a user access protocol packet and 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, 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.

Abstract: This application provides a packet processing method, a UP device, and a CP device, and belongs to the field of communication technologies. In the method, when receiving a packet, a UP device matches information in the packet with information about a user having a fixed IP address. If the matching succeeds, the UP device sends the packet to a CP device.

Abstract: 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.
