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.
Claims20
A user plane (UP) device, comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing a program that is executable by the at least one processor, the program including instructions to cause the UP device to perform:
- generating a first packet forwarding control protocol (PFCP) message based on an interface on the UP device, wherein the first PFCP message comprises information about the interface, the interface comprises a first interface accessed by a terminal on the UP device, and the information about the interface comprises an index identifying the interface;
- and
- sending, by the UP device, the first PFCP message to a control plane (CP) device, wherein the UP device and the CP device are located in a network in which a CP and a UP are separated.
A control plane (CP) device, comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing a program that is executable by the at least one processor, the program including instructions to cause the CP device to perform:
- receiving a first packet forwarding control protocol (PFCP) message from a user plane (UP) device, wherein the first PFCP message comprises information about an interface on the UP device, and the information about the interface comprises an index identifying the interface, the interface comprises a first interface accessed by a terminal on the UP device, and wherein the UP device and the CP device are located in a network in which a CP and a UP are separated;
- and
- storing the information about the interface.
A network system in which a control plane (CP) and a user plane (UP) are separated, the network system comprises a CP device and a UP device,
- wherein the UP device is configured to:
- generate a first packet forwarding control protocol (PFCP) message based on an interface on the UP device, wherein the first PFCP message comprises information about the interface, the interface comprises a first interface accessed by a terminal on the UP device, and the information about the interface comprises an index identifying the interface;
- and
- send the first PFCP message to the CP device;
- wherein the CP device is configured to:
- receive the first PFCP message from the UP device;
- and
- store the information about the interface;
- and
- wherein the network system comprises a broadband network gateway (BNG) or a broadband remote access server (BRAS).
