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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 4) 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. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 7) The method of claim 7, wherein the second network element is the law enforcement monitoring facility. ### Claim 9 (depends on 1) The method of claim 1, wherein the target vehicle list is encrypted, and wherein the authorized vehicles and roadside units have decryption keys. ### Claim 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. ### Claim 11 (depends on 10) 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. ### Claim 12 (depends on 10) 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. ### Claim 13 (depends on 10) 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. ### Claim 14 (depends on 13) 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. ### Claim 15 (depends on 10) 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. ### Claim 16 (depends on 10) 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. ### Claim 17 (depends on 16) The network element of claim 16, wherein the second network element is the law enforcement monitoring facility. ### Claim 18 (depends on 10) The network element of claim 10, wherein the target vehicle list is encrypted, and wherein the authorized vehicles and roadside units have decryption keys. ### Claim 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. ### Claim 20 (depends on 19) 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.
