Method and system for vehicle location tracking using V2X communication
A method at a network element within a Vehicle to Everything (V2X) Communications Domain, the method including receiving a tracking request at the network element for a target vehicle, the tracking request including identifying information for the target vehicle; creating a target vehicle list based on the tracking request; distributing the target vehicle list to at least one V2X endpoint; 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.
1. A method at a Vehicle to Everything (V2X) endpoint, the method comprising:
receiving a target vehicle list at the V2X endpoint, the target vehicle list being signed by a trusted issuing authority, the target vehicle list comprising linkage values or hashed values of certificates issued to one or more vehicles;
obtaining information from at least one vehicle proximate the V2X endpoint;
determining information from the at least one vehicle matches information found within the target vehicle list using the linkage values or hashed values in the target vehicle list; and
sending a sighting report from the V2X endpoint to a network element.
2. The method of claim 1 , wherein the obtaining information comprises receiving a communication from at least one vehicle.
3. The method of claim 2 , wherein the determining information from the at least one vehicle matches information found within the target vehicle list comprises:
extracting a certificate from the communication; and
finding that the certificate matches certificate information within the target vehicle list.
4. The method of claim 1 , wherein the obtaining information comprises capturing an image at a camera at the V2X endpoint.
5. The method of claim 4 , wherein the determining information from the at least one vehicle matches information found within the target vehicle list comprises determining that the image contains a vehicle characteristic listed in the target vehicle list.
6. The method of claim 1 , wherein the obtaining information comprises both receiving a communication from at least one vehicle and capturing an image of the at least one vehicle at a camera at the V2X endpoint; and wherein determining information from the at least one vehicle matches information found within the target vehicle list comprises:
extracting a certificate from the communication; and
finding that the certificate matches certificate information within the target vehicle list; and
determining that the image contains a vehicle characteristic listed in the target vehicle list.
7. The method of claim 1 , wherein the V2X endpoint comprises exclusively an authorized vehicle or roadside unit within a geographic region.
8. The method of claim 7 , wherein the target vehicle list is encrypted, and wherein the V2X endpoint has a decryption key for the target vehicle list.
9. The method of claim 1 , 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.
10. The method of claim 1 , wherein the trusted issuing authority is a Lawful Tracking Authority.
11. A Vehicle to Everything (V2X) endpoint comprising:
a processor; and
a communications subsystem,
wherein the V2X endpoint is configured to:
receive a target vehicle list at the V2X endpoint, the target vehicle list being signed by a trusted issuing authority, the target vehicle list comprising linkage values or hashed values of certificates issued to one or more vehicles;
obtain information from at least one vehicle proximate the V2X endpoint;
determine information from the at least one vehicle matches information found within the target vehicle list using the linkage values or hashed values in the target vehicle list; and
send a sighting report from the V2X endpoint to a network element.
12. The V2X endpoint of claim 11 , wherein the V2X endpoint is configured to obtain information by receiving a communication from at least one vehicle.
13. The V2X endpoint of claim 12 , wherein the V2X endpoint is configured to determine information from the at least one vehicle matches information found within the target vehicle list by:
extracting a certificate from the communication; and
finding that the certificate matches certificate information within the target vehicle list.
14. The V2X endpoint of claim 11 , wherein the V2X endpoint is configured to obtain information by capturing an image at a camera at the V2X endpoint.
15. The V2X endpoint of claim 14 , wherein the V2X endpoint is configured to determine information from the at least one vehicle matches information found within the target vehicle list by determining that the image contains a vehicle characteristic listed in the target vehicle list.
16. The V2X endpoint of claim 11 , wherein the V2X endpoint is configured to obtain information comprises both receiving a communication from at least one vehicle and capturing an image of the at least one vehicle at a camera at the V2X endpoint; and wherein the V2X endpoint is configured to determine information from the at least one vehicle matches information found within the target vehicle list by:
extracting a certificate from the communication; and
finding that the certificate matches certificate information within the target vehicle list; and
determining that the image contains a vehicle characteristic listed in the target vehicle list.
17. The V2X endpoint of claim 11 , wherein the V2X endpoint comprises exclusively an authorized vehicle or roadside unit within a geographic region.
18. The V2X endpoint of claim 17 , wherein the target vehicle list is encrypted, and wherein the V2X endpoint has a decryption key for the target vehicle list.
19. The V2X endpoint of claim 11 , 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.
20. A non-transitory computer readable medium for storing instruction code, which, when executed by a processor of a Vehicle to Everything (V2X) endpoint, cause the V2X endpoint to:
receive a target vehicle list at the V2X endpoint, the target vehicle list being signed by a trusted issuing authority, the target vehicle list comprising linkage values or hashed values of certificates issued to one or more vehicles;
obtain information from at least one vehicle proximate the V2X endpoint;
determine information from the at least one vehicle matches information found within the target vehicle list using the linkage values or hashed values in the target vehicle list; and
send a sighting report from the V2X endpoint to a network element.
