Method and system for vehicle location tracking using V2X communication

1. A method at a network element within a Vehicle to Everything (V2X) Communications Domain, the method comprising:

receiving a tracking request at the network element from a law enforcement monitoring facility for a target vehicle, the tracking request including identifying information for the target vehicle;

creating a target vehicle list based on the tracking request, the target vehicle list having linkage values or hashed values of certificates issued to the target vehicle; and

distributing the target vehicle list to at least one V2X endpoint, wherein the distributing is limited to a geographic region, and wherein the at least one V2X endpoint comprises exclusively authorized vehicles and roadside units within the geographic region.

2. The method of claim 1 , wherein the creating the target vehicle list comprises updating an existing target vehicle list with the information from the tracking request.

3. The method of claim 1 , wherein the creating the target vehicle list comprises:

forwarding the information to one or more of a Linkage Authority, Registration Authority or Pseudonym Certificate Authority;

receiving information for the target vehicle; and

building or appending the target vehicle list with the received information for the target vehicle.

4. The method of claim 1 , further comprising receiving a sighting report from the at least one V2X endpoint, wherein the sighting report includes one or more of: vehicle identification; vehicle location; license plate information for the target vehicle; images of the target vehicle; make of the target vehicle; model of the target vehicle; color of the target vehicle; V2X messages from the target vehicle; or sensor readings for the target vehicle.

5. The method of claim 4 , further comprising:

updating the target vehicle list with information from the sighting report to generate an updated target vehicle list; and

disseminating the updated target vehicle list to the at least one V2X endpoint.

6. The method of claim 1 , wherein the method further comprises sharing target vehicle list entries with other tracking network elements within the V2X communications domain.

7. The method of claim 1 , further comprising:

receiving at least one sighting report from the at least one V2X endpoint; and

forwarding the at least one sighting report to a second network element, the forwarding comprising periodically aggregating a plurality of sighting reports.

8. The method of claim 7 , wherein the second network element is the law enforcement monitoring facility.

9. The method of claim 1 , wherein the target vehicle list is encrypted, and wherein the authorized vehicles and roadside units have decryption keys.

10. A network element within a Vehicle to Everything (V2X) Communications Domain, the network element comprising:

a processor; and

a communications subsystem,

wherein the network element is configured to:

receive a tracking request at the network element from a law enforcement monitoring facility for a target vehicle, the tracking request including identifying information for the target vehicle;

create a target vehicle list based on the tracking request, the target vehicle list having linkage values or hashed values of certificates issued to the target vehicle; and

distribute the target vehicle list to at least one V2X endpoint, wherein the network element is configured to distribute to a limited geographic region, and wherein the at least one V2X endpoint comprises exclusively authorized vehicles and roadside units within the limited geographic region.

11. The network element of claim 10 , wherein the network element is configured to create the target vehicle list by updating an existing target vehicle list with the information from the tracking request.

12. The network element of claim 10 , wherein the network element is configured to create the target vehicle list by:

forwarding the information to one or more of a Linkage Authority, Registration Authority or Pseudonym Certificate Authority;

receiving information for the target vehicle; and

building or appending the target vehicle list with the received information for the target vehicle.

13. The network element of claim 10 , wherein the network element is further configured to receive a sighting report from the at least one V2X endpoint, wherein the sighting report includes one or more of: vehicle identification; vehicle location; license plate information for the target vehicle; images of the target vehicle; make of the target vehicle; model of the target vehicle; color of the target vehicle; V2X messages from the target vehicle; or sensor readings for the target vehicle.

14. The network element of claim 13 , wherein the network element is further configured to:

update the target vehicle list with information from the sighting report to generate an updated target vehicle list; and

disseminate the updated target vehicle list to the at least one V2X endpoint.

15. The network element of claim 10 , wherein the network element is further configured to share target vehicle list entries with other tracking network elements within the V2X communications domain.

16. The network element of claim 10 , wherein the network element is further configured to:

receive at least one sighting report from the at least one V2X endpoint; and

forward the at least one sighting report to a second network element, the forwarding comprising periodically aggregating a plurality of sighting reports.

17. The network element of claim 16 , wherein the second network element is the law enforcement monitoring facility.

18. The network element of claim 10 , wherein the target vehicle list is encrypted, and wherein the authorized vehicles and roadside units have decryption keys.

19. A non-transitory computer readable medium for storing instruction code, which, when executed by a processor of a network element within a Vehicle to Everything (V2X) Communications Domain cause the network element to:

receive a tracking request at the network element from a law enforcement monitoring facility for a target vehicle, the tracking request including identifying information for the target vehicle;

create a target vehicle list based on the tracking request, the target vehicle list having linkage values or hashed values of certificates issued to the target vehicle; and

distribute the target vehicle list to at least one V2X endpoint, wherein the network element is configured to distribute to a limited geographic region, and wherein the at least one V2X endpoint comprises exclusively authorized vehicles and roadside units within the limited geographic region.

20. The non-transitory computer readable medium of claim 19 , wherein the instruction code causes the network element to create the target vehicle list by updating an existing target vehicle list with the information from the tracking request.
