Abstract

A method for providing wireless connection capability for a telematics unit including determining a connection failure between the telematics unit and a call center, providing the telematics unit with an alternative cellular identifier pair at the telematics unit based on the determination and attempting to establish a connection between the telematics unit and the call center using the alternative cellular identifier pair.

Claims

1. A method for providing wireless connection capability for a telematics unit comprising:

determining a connection failure between the telematics unit and a call center;

providing the telematics unit with an alternative cellular identifier pair at the telematics unit based on the determination; and

attempting to establish a connection between the telematics unit and the call center using the alternative cellular identifier pair.

2. The method of claim 1, wherein the attempt to establish a connection between the telematics unit and the call center using the alternative cellular identifier pair is an attempt to establish a non-authenticated call wireless connection between the telematics unit and the call center.

3. The method of claim 1, further comprising:

attempting to establish a connection between the telematics unit and the call center using standard telematics procedures.

4. The method of claim 1, wherein providing the telematics unit with an alternative cellular identifier pair at the telematics unit based on the determination comprises:

retrieving the alternative cellular identifier pair from a memory in the telematics unit; and

reprogramming a network access device in the telematics unit with the alternative cellular identifier pair.

5. The method of claim 1, wherein the alternative cellular identifier pair comprises an alternative mobile identification number and an electronic serial number for a network access device.

6. The method of claim 1, further comprising:

determining a connection failure between the telematics unit and the call center using the alternative cellular identifier pair;

providing the telematics unit with a revised cellular code at the telematics unit based on the determination of a connection failure between the telematics unit and the call center using the alternative cellular identifier pair; and

attempting to establish a connection between the telematics unit and the call center using the revised cellular code.

7. The method of claim 6, wherein providing the telematics unit with a revised cellular code at the telematics unit based on the determination comprises:

retrieving the revised cellular code from a memory in the telematics unit; and

reprogramming a network access device in the telematics unit with the revised cellular code.

8. The method of claim 6, wherein the revised cellular code comprises an electronic serial number and a revised mobile identification number for a network access device.

9. The method of claim 8 wherein the revised cellular code further comprises a control channel information including encoded call information.

10. The method of claim 6, further comprising:

receiving call information at the call center responsive to the attempt to establish a connection between the telematics unit and the call center using the revised cellular code; and

determining an action based on the received call information.

11. The method of claim 10, wherein the received call information is selected from the group consisting of customer specific information, call specific information, vehicle location information and combinations thereof.

12. The method of claim 10, wherein the determined action is selected from the group consisting of sending at least one emergency vehicle to a vehicle location, placing a call from the call center to the telematics unit, placing a call to a residence of the subscriber, sending an email to the subscriber, reporting theft of a vehicle to a law enforcement agency, and combinations thereof.

13. The method of claim 1, further comprising:

reprogramming a network access device in the telematics unit with aninitial mobile identification number/electronic serial number pair after the connection is terminated.

14. A system for providing wireless connection capability for a telematics unit comprising:

means for determining a connection failure between the telematics unit and a call center;

means for providing the telematics unit with an alternative cellular identifier pair including an alternative mobile identification number at the telematics unit based on the determination; and

means for attempting to establish a connection between the telematics unit and the call center using the alternative cellular identifier pair.

15. The system of claim 14, further comprising:

means for determining a connection failure between the telematics unit and the call center using the alternative cellular identifier pair;

means for providing the telematics unit with a revised cellular code including an alternative mobile identification number at the telematics unit based on the determination of a connection failure between the telematics unit and the call center using the alternative cellular identifier pair; and

means for attempting to establish a connection between the telematics unit and the call center using the revised cellular code.

16. The system of claim 14, further comprising:

means for receiving call information at the call center responsive to the attempt to establish a connection between the telematics unit and the call center using a revised cellular code; and

means for determining an action based on the received call information.

17. The system of claim 14, further comprising:

means for reprogramming a network access device in the telematics unit with aninitial mobile identification number/electronic serial number pair after the connection is terminated.

18. A computer readable medium storing a computer program comprising:

computer readable code for determining a connection failure between the telematics unit and a call center;

computer readable code for providing the telematics unit with an alternative cellular identifier pair including an alternative mobile identification number at the telematics unit based on the determination; and

computer readable code for attempting to establish a connection between the telematics unit and the call center using the alternative cellular identifier pair.

19. The medium of claim 18, wherein computer readable code for providing the telematics unit with an alternative cellular identifier pair at the telematics unit based on the determination comprises:

computer readable code for retrieving the alternative cellular identifier pair number from a memory in the telematics unit; and

computer readable code for reprogramming a network access device in the telematics unit with the alternative cellular identifier pair.

20. The medium of claim 18, further comprising:

computer readable code for determining a connection failure between the telematics unit and a call center using the alternative cellular identifier pair;

computer readable code for providing the telematics unit with a revised cellular code including a revised mobile identification number at the telematics unit based on the determination of a connection failure between the telematics unit and a call center using the alternative cellular identifier pair; and

computer readable code for attempting to establish a connection between the telematics unit and the call center using the revised cellular code.

21. The medium of claim 20, wherein providing the telematics unit with a revised cellular code at the telematics unit based on the determination comprises:

computer readable code for retrieving the revised cellular code from a memory in the telematics unit; and

computer readable code for reprogramming a network access device in the telematics unit with the revised cellular code.

22. The medium of claim 20, further comprising:

computer readable code for receiving call information at the call center responsive to the attempt to establish a connection between the telematics unit and the call center using the revised cellular code; and

computer readable code for determining an action based on the received call information.

23. The medium of claim 18, further comprising:

computer readable code for reprogramming a network access device in the telematics unit with an initial mobile identification number/electronic serial number pair after the connection is terminated.
