Abstract

A data processing method includes receiving by an access network device a vehicle-to-everything (V2X) communication parameter of a group member device. The method also includes storing, by the access network device, the V2X communication parameter with context about a group to which the group member device belongs. The V2X communication parameter is used for allocation of a ProSe communication 5 (PC5) resource to the group member device.

First claim

What is claimed is:

1. A data processing method, comprising:
receiving, by an access network device, a vehicle-to-everything (V2X) communication parameter of a group member device, wherein the V2X communication parameter is received from a policy control function (PCF) entity, and the V2X communication parameter is sent to the access network device by the PCF entity in response to the PCF entity receiving indication information that indicates a connection has been established between the group member device and a group control device; and
storing, by the access network device, the V2X communication parameter with context about a group to which the group member device belongs, wherein the V2X communication parameter is used for allocation of a ProSe communication 5 (PC5) resource to the group member device,
wherein the V2X communication parameter comprises V2X authorization information of the group member device and a PC5 quality of service (QOS) parameter of the group member device.

2. The method according to claim 1 , wherein the method further comprises:
allocating, by the access network device, the PC5 resource to the group member device based on the V2X communication parameter; and
sending, by the access network device, information about the PC5 resource to the group control device.

3. The method according to claim 2 , wherein the method further comprises:
receiving, by the access network device, a PC5 resource request message from the group control device, wherein the PC5 resource request message requests allocation of the PC5 resource to the group member device; and
allocating, by the access network device, the PC5 resource to the group member device based on the PC5 resource request message and the V2X communication parameter.

4. The method according to claim 3 , wherein the allocating, by the access network device, the PC5 resource to the group member device based on the PC5 resource request message and the V2X communication parameter comprises:
performing, by the access network device, authorization check on the group member device based on the V2X communication parameter;
based on a determination that the group member device is successfully authorized, allocating, by the access network device, the PC5 resource to the group member device; and
sending, by the access network device, the information about the PC5 resource to the group control device.

5. The method according to claim 3 , wherein the PC5 resource request message comprises at least one of a group member identification number of the group member device, a PC5 quality of service identifier (PQI) of the group member device, a PC5 quality of service (QOS) flow identifier of the group member device, or a data volume of the group member device.

6. A data processing method, comprising:
receiving, by a policy control function (PCF) entity, indication information, wherein the indication information indicates that a connection has been established between a group member device and a group control device;
in response to receiving the indication information, obtaining, by the PCF entity, a vehicle-to-everything (V2X) communication parameter of the group member device; and
sending, by the PCF entity, the V2X communication parameter to an access network device accessed by a group control device in a group to which the group member device belongs,
wherein the V2X communication parameter comprises V2X authorization information of the group member device and a ProSe communication 5 (PC5) quality of service (QOS) parameter of the group member device.

7. The method according to claim 6 , wherein the obtaining,
by the PCF entity, the V2X communication parameter of the group member device comprises:
obtaining, by the PCF entity, a locally stored V2X communication parameter based on the indication information.

8. The method according to claim 6 , wherein the receiving, by the PCF entity, the indication information comprises:
receiving, by the PCF entity, the indication information from an application server (AS).

9. The method according to claim 6 , wherein the method further comprises:
performing, by the PCF entity, authorization check on the group member device based on the V2X communication parameter; and
based on a determination that the group member device is successfully authorized, associating, by the PCF entity, the group member device with the group control device.

10. The method according to claim 6 , wherein the method further comprises:
receiving, by the PCF entity, a group member identification number of the group member device from the group control device.

11. The method according to claim 10 , wherein the method further comprises:
sending, by the PCF entity, the group member identification number to the access network device.

12. The method according to claim 10 , wherein after allocating, by the PCF entity, a group member identification number to the group member device, the method further comprises:
sending, by the PCF entity, the group member identification number to the group member device.

13. A data processing method, comprising:
establishing, by a group control device, a connection to a group member device based on a vehicle-to-everything (V2X) communication parameter of the group member device; and
sending, by the group control device, indication information to a policy control function (PCF) entity to cause the PCF entity to send the V2X communication parameter to an access network device accessed by the group control device in a group to which the group member device belongs, wherein the indication information indicates that the connection has been established between the group control device and the group member device,
wherein the V2X communication parameter comprises V2X authorization information of the group member device and a ProSe communication 5 (PC5) quality of service (QOS) parameter of the group member device.

14. The method according to claim 13 , wherein the method further comprises:
receiving, by the group control device, a PC5 resource request message from the group member device;
sending, by the group control device, the PC5 resource request message to an access network device;
receiving, by the group control device from the access network device, information about a PC5 resource allocated to the group member device; and
allocating, by the group device, the PC5 resource to the group member device based on the information about the PC5 resource.

15. The method according to claim 13 , wherein the method further comprises:
sending, by the group control device, a group member identification number to the group member device.

16. The method according to claim 15 , wherein the method further comprises:
allocating, by the group control device, the group member identification number to the group member device.

17. The method according to claim 15 , wherein the method further comprises:
receiving, by the group control device, the group member identification number from the PCF entity.

18. The method according to claim 15 , wherein the method further comprises:
receiving, by the group control device, the group member identification number from the access network device.
