Abstract

A method for providing telematics unit information includes generating an awareness message at a telematics unit, the awareness message including a subscriber status wherein the subscriber status includes location and state information, assigning a current value to the subscriber status, and sending the awareness message with the current value from the telematics unit to a telematics call center. A computer usable medium with suitable computer program code is employed for providing telematics unit information.

Claims

1. A method for providing telematics unit information, the method comprising:

generating an awareness message at a telematics unit, the awareness message including a subscriber status wherein the subscriber status includes location and state information;

assigning a current value to the subscriber status; and

sending the awareness message with the current value from the telematics unit to a telematics call center.

2. The method of claim 1 further comprising:

modifying the subscriber status to include a plurality of data elements wherein the plurality of data elements include an identification field, a mode field, and a location field.

3. The method of claim 2 wherein each of the plurality the data elements include a field identifier and a corresponding field value wherein the field identifier and the corresponding field value are delimited by a field separator.

4. The method of claim 2 wherein the field value associated with the mode field of the subscriber status is selected from the group consisting of on, standby, sleep, in-session, out of session, and off.

5. The method of claim 2 wherein the field value associated with the location field includes a plurality of data points corresponding to latitude, longitude, aged, speed, and direction.

6. The method of claim 2 wherein the field value associated with the identification field includes a telematics unit identification number.

7. The method of claim 2 wherein the field value corresponding to the location field is encrypted.

8. The method of claim 1 further comprising:

determining the current value of the subscriber status.

9. The method of claim 1 further comprising:

receiving services at the telematics unit from the telematics call center based on the subscriber status.

10. The method of claim 1 wherein sending the awareness message with the current value from the telematics unit to a telematics call center further comprises:

receiving a request from a telematics call center to send the awareness message; and

sending the awareness message from the telematics unit to the call center responsive to the request.

11. The method of claim 1 wherein the awareness message is a session initiation protocol (SIP) request.

12. The method of claim 1 wherein the subscriber status is a user parameter of a session initiation protocol SIP register message.

13. A system for providing telematics unit information the system comprising:

means for generating an awareness message at a telematics unit, the awareness message including a subscriber status wherein the subscriber status includes location and state information;

means for assigning a current value to the subscriber status; and

means for sending the awareness message with the current value from the telematics unit to a telematics call center.

14. The system of claim 13 further comprising:

means for modifying the subscriber status to include a plurality of data elements wherein the plurality of data elements include an identification field, a mode field, and a location field.

15. The method of claim 13 further comprising:

means for determining the current value of the subscriber status.

16. The system of claim 13 further comprising:

means for receiving services at the telematics unit from the telematics call center based on the subscriber status.

17. A computer readable medium storing a computer program including computer program code for providing telematics unit information the computer readable medium comprising:

computer program code for generating an awareness message at a telematics unit, the awareness message including a subscriber status wherein the subscriber status includes location and state information;

computer program code for assigning a current value to the subscriber status; and

computer program code for sending the awareness message with the current value from the telematics unit to a telematics call center.

18. The computer readable medium of claim 17 further comprising:

computer program code for modifying the subscriber status to include a plurality of data elements wherein the plurality of data elements include an identification field, a mode field, and a location field.

19. The computer readable medium of claim 17 further comprising:

computer program code for determining the current value of the subscriber status.

20. The computer readable medium of claim 17 further comprising:

computer program code for receiving services at the telematics unit from the telematics call center based on the subscriber status.
