Abstract

The invention provides a method for obtaining an internet connection. The method provides for sending an internet connection request from a call center to a vehicle telematics unit and for providing an IP address and server call in parameters to the vehicle telematics unit. The method also receives an internet connection at the provided IP address with the server call in parameters from the telematics unit at the call center.

Claims

1. A method of obtaining an internet connection, the method comprising:

sending an internet connection request from a call center to a vehicle telematics unit;

providing an IP address and server call in parameters to the vehicle telematics unit; and

receiving an internet connection at the provided IP address with the server call in parameters from the telematics unit at the call center.

2. The method of claim 1 wherein the telematics unit connects to an internet server with the server call in parameters at the provided IP address.

3. The method of claim 2 wherein the internet server is controlled by the call center.

4. The method of claim 1 wherein the server call in parameters comprise:

a TCP port number;

a connection failure timeout, and

a service type.

5. The method of claim 1 wherein the internet connection request is provided via telephony.

6. The method of claim 5 wherein the internet connection request is provided via the telephony connection when a preestablished connection exists between the telematics unit and the call center.

7. The method of claim 1 wherein the internet connection request is provided via SMS.

8. The method of claim 7 wherein the internet connection request is provided via SMS when no preestablished connection exists between the telematics unit and the call center.

9. A computer usable medium including a program for obtaining an internet connection comprising:

computer readable program code for sending an internet connection request from a call center to a vehicle telematics unit;

computer readable program code for providing an IP address and server call in parameters to the vehicle telematics unit; and

computer readable program code for receiving an internet connection at the provided IP address with the server call in parameters from the telematics unit at the call center.

10. The computer usable medium of claim 9 further comprising:

computer readable program code for the telematics unit to connect to an internet server with the server call in parameters at the provided IP address.

11. The computer usable medium of claim 9 wherein the computer readable program code for server call in parameters further comprises:

computer readable program code for a TCP port number;

computer readable program code for a connection failure timeout; and

computer readable program code for a service type.

12. The computer usable medium of claim 9 further comprising:

computer readable program code for providing the internet connection request via telephony.

13. The computer usable medium of claim 12 further comprising:

computer readable program code for the internet connection request to be provided via telephony when a preestablished connection exists between the telematics unit and the call center.

14. The computer usable medium of claim 9 further comprising:

computer readable program code for providing the internet connection request via SMS.

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

computer readable program code for the internet connection request to be provided via SMS when no preestablished connection exists between the telematics unit and the call center.

16. A system for obtaining an internet connection comprising:

means for sending an internet connection request from a call center to a vehicle telematics unit;

means for providing an IP address and server call in parameters to the vehicle telematics unit; and

means for receiving an internet connection at the provided IP address with the server call in parameters from the telematics unit at the call center.

17. The system of claim 16 further comprising:

means for the telematics unit to connect to an internet server with the server call in parameters at the provided IP address.

18. The system of claim 17 further comprising:

means for the internet server to be controlled by the call center.

19. The system of claim 16 wherein the server call in parameters further comprise:

a TCP port number;

a connection failure time out; and

a service type.
