Abstract

Methods and devices for implementing the methods for communicating vehicle-to-everything (V2X) information to a network node include transmitting a first V2X message that is associated with a first service and that includes an identifier of a second service, and transmitting a second V2X message that is associated with the second service and that includes an identifier of the first service configured to enable the network node to use information from the first V2X message with the second service. The network node may receive the first V2X message and the second V2X message, and may use information from the first V2X message with the second service.

First claim

What is claimed is:

1. A method performed by a processor of a vehicle-to-everything (V2X) node for communicating V2X information to a network node, comprising:
transmitting a first V2X message that is associated with a first service and that includes an identifier of a second service; and
transmitting a second V2X message that is associated with the second service and that includes an identifier of the first service configured to enable the network node to use information from the first V2X message with the second service.

2. The method of claim 1 , further comprising
generating the identifier of the first service from a signing certificate of the first service that is associated with the V2X node; and
generating the identifier of the second service from a signing certificate of the second service that is associated with the V2X node.

3. The method of claim 2 , wherein
generating the identifier of the first service from a signing certificate of the first service that is associated with the V2X node includes generating a hash of the signing certificate of the first service; and
generating the identifier of the second service from a signing certificate of the second service that is associated with the V2X node includes generating a hash of the signing certificate of the second service.

4. The method of claim 2 , wherein:
generating the identifier of the first service from a signing certificate of the first service that is associated with the V2X node includes generating a truncated identifier of the signing certificate of the first service; and
generating the identifier of the second service from a signing certificate of the second service that is associated with the V2X node includes generating a truncated identifier of the signing certificate of the second service.

5. The method of claim 2 , further comprising transmitting a third V2X message that is associated with the second service and that includes a truncated identifier of the first service.

6. The method of claim 1 , wherein the second V2X message is one of a tolling message, a parking access message, a road condition message, a geonetworking message, a basic safety message or an emergency message.

7. A vehicle-to-everything (V2X) node, comprising:
a processor configured with processor-executable instructions to:
transmit to a network node a first V2X message that is associated with a first service and that includes an identifier of a second service; and
transmit to the network node a second V2X message that is associated with the second service and that includes an identifier of the first service configured to enable the network node to use information from the first V2X message with the second service.

8. The V2X node of claim 7 , wherein the processor is further configured with processor-executable instructions to:
generate the identifier of the first service from a signing certificate of the first service that is associated with the V2X node; and
generate the identifier of the second service from a signing certificate of the second service that is associated with the V2X node.

9. The V2X node of claim 8 , wherein the processor is further configured with processor-executable instructions to:
generate a hash of the signing certificate of the first service; and
generate a hash of the signing certificate of the second service.

10. The V2X node of claim 8 , wherein the processor is further configured with processor-executable instructions to:
generate a truncated identifier of the signing certificate of the first service; and
generate a truncated identifier of the signing certificate of the second service.

11. The V2X node of claim 8 , wherein the processor is further configured with processor-executable instructions to transmit a third V2X message that is associated with the second service and that includes a truncated identifier of the first service.

12. The V2X node of claim 7 , wherein the processor is further configured with processor-executable instructions such that the second V2X message is one of a tolling message, a parking access message, a road condition message, a geonetworking message, a basic safety message, or an emergency message.

13. A vehicle-to-everything (V2X) node, comprising:
means for transmitting to a network node a first V2X message that is associated with a first service and that includes an identifier of a second service; and
means for transmitting to the network node a second V2X message that is associated with the second service and that includes an identifier of the first service configured to enable the network node to use information from the first V2X message with the second service.

14. The V2X node of claim 13 , further comprising:
means for generating the identifier of the first service from a signing certificate of the first service that is associated with the V2X node; and
means for generating the identifier of the second service from a signing certificate of the second service that is associated with the V2X node.

15. The V2X node of claim 14 , wherein
means for generating the identifier of the first service from a signing certificate of the first service that is associated with the V2X node includes means for generating a hash of the signing certificate of the first service; and
means for generating the identifier of the second service from a signing certificate of the second service that is associated with the V2X node includes means for generating a hash of the signing certificate of the second service.

16. The V2X node of claim 14 , wherein:
means for generating the identifier of the first service from a signing certificate of the first service that is associated with the V2X node includes means for generating a truncated identifier of the signing certificate of the first service; and
means for generating the identifier of the second service from a signing certificate of the second service that is associated with the V2X node includes means for generating a truncated identifier of the signing certificate of the second service.

17. The V2X node of claim 14 , further comprising means for transmitting a third V2X message that is associated with the second service and that includes a truncated identifier of the first service.

18. The V2X node of claim 13 , wherein the second V2X message is one of a tolling message, a parking access message, a road condition message, a geonetworking message, a basic safety message, or an emergency message.

19. A method performed by a processor of a network node for receiving vehicle-to-everything (V2X) information from a V2X node, comprising:
receiving from a V2X node a first V2X message that is associated with a first service and that includes an identifier of a second service;
receiving from the V2X node a second V2X message that is associated with the second service and that includes an identifier of the first service; and
using information from the first V2X message with the second service.

20. The method of claim 19 , wherein using information from the first V2X message with the second service includes generating an association of the V2X node, the first service, and the second service that enables the network node to use information from the first V2X message with the second service.

21. The method of claim 19 , wherein using information from the first V2X message with the second service includes:
obtaining information about the V2X node from the first V2X message; and
performing an operation for the V2X node related to t
