Abstract

A method of registering a vehicle with a call center of a telematics system may entail turning a key within a vehicle ignition to begin a call from a telematics control module within the vehicle to a server at a telematics call center, connecting the telematics control module within the vehicle to the server at the telematics service center, sending a health check request from the telematics control module within the vehicle to the server at the telematics service center; and receiving a health check confirmation in the telematics control module within the vehicle from the server at the telematics service center. The method may further entail inquiring if such a health check request request-confirmation was successful. The method may also include a call fail counter and a message fail counter to automatically re-initiate a health check request and a successful answer to such a request.

Claims

1. A method of registering a vehicle with a call center of a telematics system, the method comprising:

turning a key within a vehicle ignition of a vehicle;

invoking a call from a telematics control module within the vehicle to a server at a telematics call center;

connecting the telematics control module within the vehicle to the server at the telematics service center;

exchanging messages between the telematics control module and the telematics service center, wherein exchanging messages further comprises;

sending a health check request from the telematics control module within the vehicle to the server at the telematics service center; and

receiving a health check confirmation in the telematics control module within the vehicle from the server at the telematics service center;

inquiring if sending a health check request from the telematics control module within the vehicle to the server at the telematics service center and receiving a health check confirmation in the telematics control module within the vehicle from the server at the telematics service center was successful; and

inquiring if sending a health check request from the telematics control module within the vehicle to the server at the telematics service center and receiving a health check confirmation in the telematics control module within the vehicle to the server at the telematics service center was successful; and

inquiring whether the call was dropped when a negative response to inquiring if sending a health check request from the telematics control module within the vehicle to the server at the telematics service center and receiving a health check confirmation in the telematics control module within the vehicle to the server at the telematics service center was successful.

2. The method of claim 1, further comprising:

confirming that exchanging messages has failed.

3. The method of claim 2, further comprising:

inquiring if a message fail counter is less than a predetermined number.

4. The method of claim 3, further comprising:

when a message fail counter is less than a predetermined number, re-sending the health check request from the telematics control module within the vehicle to the server at the telematics service center and receiving the health check confirmation in the telematics control module within the vehicle from the server at the telematics service center.

5. A method of registering a vehicle with a call center of a telematics system, the method comprising:

turning a key within a vehicle ignition of a vehicle;

invoking a call from a telematics control module within the vehicle to a server at a telematics call center;

inquiring whether the call from a telematics control module within the vehicle to a server at a telematics call center is connected;

determining that the call from a telematics control module within the vehicle to a server at a telematics call center is not connected; and

inquiring whether a call failure counter is less than a predetermined number.

6. The method according to claim 5, further comprising:

determining that a call failure counter is less than the predetermined number;

increasing the call failure counter by one; and

setting a message failure counter to zero.

7. The method according to claim 5, further comprising:

determining that a call failure counter is not less than the predetermined number; and

setting the call failure counter to zero.

8. A method of registering a vehicle with a call center of a telematics system, the method comprising:

turning a key within a vehicle ignition of a vehicle;

invoking a call from a telematics control module within the vehicle to a server at a telematics call center;

connecting the telematics control module within the vehicle to the server at the telematics service center;

exchanging messages between the telematics control module and the telematics service center, wherein exchanging messages comprises;

sending a health check request from the telematics control module within the vehicle to the server at the telematics service center; and

receiving a health check confirmation in the telematics control module within the vehicle from the server at the telematics service center;

inquiring if sending a health check request from the telematics control module within the vehicle to the server at the telematics service center and receiving a health check confirmation in the telematics control module within the vehicle from the server at the telematics service center was successful;

inquiring whether the call was dropped upon confirming that sending a health check request from the telematics control module within the vehicle to the server at the telematics service center and receiving a health check confirmation in the telematics control module within the vehicle to the server at the telematics service center was not successful; and

inquiring whether a call failure counter is less than a predetermined number.

9. The method according to claim 8, further comprising:

determining that a call failure counter is less than the predetermined number;

increasing the call failure counter by one; and

setting a message failure counter to zero.

10. The method according to claim 8, further comprising:

determining that a call failure counter is not less than the predetermined number; and

setting the call failure counter to zero.

11. The method according to claim 8, further comprising:

determining that sending a health check request from the telematics control module within the vehicle to the server at the telematics service center and receiving a health check confirmation in the telematics control module within the vehicle to the server at the telematics service center was successful; and

registering the vehicle within a server at a telematics call center.
