Abstract

An application server in a cellular network receives incident information and determines a trust value associated with the incident information using one or more trust parameters. The application server generates a warning message including the the trust value and the one or more trust parameters. The warning message is broadcast to user equipment in vehicles in an area of relevance. The user equipment in the vehicles in the area of relevance receives the warning message and may re-evaluate the trust value in the warning message based on additional trust parameters or information. The user equipment may determine to perform one or more actions based on the trust value, such as providing a warning to a driver or performing a braking operation.

Claims

1. An application server, comprising:

a network interface configured to communicate with one or more components in a wireless network; and

a processing circuit configured to;

receive an alert message from user equipment (UE) in a vehicle over the wireless network;

process incident information included in the alert message;

determine a trust value associated with the incident information and an incident type;

insert the trust value in a trust information parameter field of a warning message;

determine an area of relevance in response to the incident type; and

transmit the warning message for broadcast by the wireless network within the area of relevance.

2. The application server of claim 1, wherein the processing circuit is configured to determine the trust value associated with the incident information by:

determining a first trust parameter of a number of UEs in the area of relevance; and

determining a second trust parameter of a number of the UEs in the area of relevance that have transmitted an alert message including the incident information.

3. The application server of claim 2, wherein the processing circuit is further configured to determine the trust value associated with the incident information by:

determining a third trust parameter of a ratio of the number of the UEs in the area of relevance that have transmitted an alert message including the incident information to the number of UEs in the area of relevance; and

evaluating the trust value using the ratio.

4. The application server of claim 1, wherein the processing circuit is further configured to:

receive the incident information from one or more third party services including one or more of;

a traffic service, weather service or news service; and

assign a higher trust value to the incident information from the one or more third party services.

5. The application server of claim 4, wherein the processing circuit is further configured to:

receive the incident information from one or more other application servers in the wireless network.

6. The application server of claim 5, wherein the processing circuit is further configured to:

receive another alert message including second incident information of a second incident from second user equipment (UE) in a vehicle over the wireless network; and

determine the second incident information relates to a same or similar incident by evaluating the second incident information, wherein the second incident information includes an incident type, predetermined time period and an area of relevance of the second incident.

7. A central server configured to track incident information, comprising:

a network interface configured to communicate with one or more components in a wireless network; and

a processing circuit configured to;

receive an alert message from user equipment (UE) in a vehicle over the wireless network;

process incident information for an incident included in the alert message and determine a first trust value associated with the incident information;

receive the incident information for the incident from a third party service; and

determine an updated trust value associated with the incident information, wherein the updated trust value is a higher trust value;

insert the updated trust value in a trust information parameter field of a warning message; and

transmit the warning message for broadcast by the wireless network within an area of relevance.

8. The central server of claim 7, wherein the processing circuit is configured to:

receive the incident information for the incident from the third party service, wherein the third party service is a traffic service.

9. The central server of claim 7, wherein the processing circuit is configured to:

receive the incident information for the incident from the third party service, wherein the third party service is a weather service.

10. The central server of claim 7, wherein the processing circuit is configured to:

receive the incident information for the incident from the third party service, wherein the third party service is a news service.

11. The central server of claim 7, wherein the processing circuit is further configured to:

receive the incident information from another application server configured to track incident information in the wireless network.

12. The central server of claim 7, wherein the processing circuit is further configured to:

determine an incident type using the incident information; and

determine the area of relevance in response to the incident type.

13. A server, comprising:

a network interface configured to communicate with vehicles over a wireless network; and

a processing circuit configured to;

receive incident information from one of the vehicles over the wireless network;

determine a trust value associated with the incident information and an incident type;

determine an area of relevance in response to the incident type;

insert the trust value in a trust information parameter field of a warning message; and

transmit the warning message for broadcast by the wireless network within the area of relevance.

14. The server of claim 13, wherein the area of relevance includes an area with a predetermined radius around an incident location, wherein the predetermined radius is determined in response to the incident type.

15. The server of claim 13, wherein the processing circuit is further configured to:

receive the incident information from a third party service; and

determine an updated trust value associated with the incident information, wherein the updated trust value is a higher trust value.

16. The server of claim 14, wherein the processing circuit is further configured to:

insert the updated trust value in the trust information parameter field of an updated warning message; and

transmit the updated warning message for broadcast by the wireless network within the area of relevance.

17. The server of claim 16, wherein the processing circuit is configured to:

receive the incident information from the third party service, wherein the third party service is a traffic service.

18. The server of claim 16, wherein the processing circuit is configured to:

receive the incident information from the third party service, wherein the third party service is a weather service.

19. The server of claim 16, wherein the processing circuit is configured to:

receive the incident information from the third party service, wherein the third party service is a news service.

20. The server of claim 13, wherein the processing circuit is further configured to:

receive the incident information from another application server configured to track incident information in the wireless network.
