Abstract

The present invention is a system and method of providing access to a telematics unit in a mobile vehicle. A telematics unit access request corresponding to the telematics unit is received, and a mobile identification number and a telematics unit identifier associated with the telematics unit are determined. The mobile identification number and the telematics unit identifier are compared with a database of identifier records, after which a calling-state message is sent to the telematics unit based on the telematics unit access request, the mobile identification number, and the telematics unit identifier.

Claims

1. A method of providing access to a telematics unit in a mobile vehicle, comprising:

receiving a telematics unit access request corresponding to the telematics unit;

determining a mobile identification number associated with the telematics unit;

determining a telematics unit identifier associated with the telematics unit;

comparing the mobile identification number and the telematics unit identifier with a database of identifier records, and

sending a calling-state message to the telematics unit based on the telematics unit access request, the mobile identification number, and the telematics unit identifier.

2. The method of claim 1 wherein the telematics unit identifier comprises at least a portion of an electronic serial number.

3. The method of claim 1 wherein the telematics unit identifier comprises a coded security number.

4. The method of claim 1 wherein the coded security number comprises a personal identification number.

5. The method of claim 1 wherein the database of identifier records comprises an account number and a billing stare associated with the telematics unit.

6. The method of claim 1 wherein the calling-state message is sent using an air-interface function.

7. The method of claim 1 further comprising:

storing an updated mobile identification number based on the calling-state message;

setting a calling-state indicator based on the calling-state message; and

enabling a cellular phone embedded in the telematics unit based on the calling-state indicator.

8. The method of claim 7 wherein the calling-state indicator comprises a billing state consisting of a pre-pay state and a post-pay state.

9. The method of claim 1 further comprising:

setting a calling-state indicator to a predefined billing state when the mobile identification number associated with the telematics unit is altered.

10. The method of claim 9 wherein the calling-state indicator comprises a billing state.

11. The method of claim 10 wherein the billing state is set to a pre-pay state.

12. The method of claim 1 further comprising:

disabling a cellular phone embedded in the telematics unit based on a calling-state indicator.

13. The method of claim 1 wherein the calling-state message includes at least one information selected from the group consisting of:

an updated MIN for the telematics unit, billing state, a pre-pay setting or a post-pay setting, updated preferred roaming list, a home station identifier, entries for an acquisition table, and parameters for establishing and maintaining wireless communications between the wireless service provider and the embedded phone.

14. A computer usable medium including a program to provide access to a telematics unit in a mobile vehicle, comprising:

computer program code to receive a telematics unit access request corresponding to the telematics unit;

computer program code to determine a mobile identification number associated with the telematics unit;

computer program code to determine a telematics unit identifier associated with the telematics unit;

computer program code to compare the mobile identification number and the telematics unit identifier with a database of identifier records; and

computer program code to send a calling-state message to the telematics unit based on the telematics unit access request, the mobile identification number, and the telematics unit identifier.

15. The computer usable medium of claim 14 further comprising:

computer program code to store an updated mobile identification number based on the calling-state message;

computer program code to set a calling-state indicator based on the calling-state message; and

computer program code to enable a cellular phone embedded in the telematics unit based on the calling-state indicator.

16. The computer usable medium of claim 14 further comprising:

computer program code to set a calling-state indicator to a predefined billing state when the mobile identification number associated with the telematics unit is altered.

17. The computer usable medium of claim 14 further comprising:

computer program code to disable a cellular phone embedded in the telematics unit based on a calling-state indicator.

18. A system for providing access to a telematics unit in a mobile vehicle, comprising:

means for receiving a telematics unit access request corresponding to the telematics unit;

means for determining a mobile identification number associated with the telematics unit;

means for determines a telematics unit identifier associated with the telematics unit;

means for comparing the mobile identification number and the telematics unit identifier with a database of identifier records; and

means for sending a calling-state message to the telematics unit based on the telematics unit access request, the mobile identification number, and the telematics unit identifier.

19. The system of claim 18 further comprising:

means for storing an updated mobile identification number based on the calling-state message;

means for setting a calling-state indicator based on the calling-state message, and

means for enabling a cellular phone embedded in the telematics unit based on the calling-state indicator.

20. The system of claim 18 further comprising:

means for setting a calling-state indicator to a predefined billing state when the mobile identification number associated with the telematics unit is altered.

21. The system of claim 18 further comprising:

means for disabling a cellular phone embedded in the telematics unit based on a calling-state indicator.
