Abstract

Claims (33)

1. A method for operating three-way calling for a telematics unit, the method comprising:

establishing a first connection between a call center and the telematics unit based on a trouble call request;

sending call instructions from the call center to the telematics unit via the first connection based on the trouble call request;

establishing a second connection from the telematics unit to one of the call center or a contact-problem number associated with the trouble call request based on the call instructions; and

monitoring the second connection at the call center to troubleshoot the telematics unit.

2. The method of claim 1 , further comprising: receiving the trouble call request at the call center from the telematics unit via a separate connection.

3. The method of claim 1 , wherein the establishing a first connection comprises maintaining a communication connection transmitting the trouble call request.

4. The method of claim 1 , wherein the establishing a first connection comprises establishing the first connection based on a determination of whether three-way calling service is available.

5. The method of claim 4 , further comprising: modifying telematics unit service at the call center to temporarily provide the three-way calling service based on the determination.

6. The method of claim 1 , further comprising:

sending termination instructions from the call center to the telematics unit via one of the first or second connections; and

terminating the second connection based on the termination instructions.

7. The method of claim 1 , wherein the call instructions are transmitted using data mode and include at least one of the contact-problem number and a telematics unit function to test.

8. The method of claim 1 , wherein the three-way calling is enabled for a mobile dial number of the telematics unit.

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

computer readable code for establishing a first connection between a call center and the telematics unit based on a trouble call request;

computer readable code for sending call instructions from the call center to the telematics unit via the first connection based on the trouble call request;

computer readable code for establishing a second connection from the telematics unit to one of the call center or a contact-problem number associated with the trouble call request based on the call instructions;

computer readable code for sending termination instructions from the call center to the telematics unit via one of the first or second connection to terminate the second connection; and

computer readable code for terminating the second connection based on the termination instructions.

10. The medium of claim 9 , further comprising: computer readable code for receiving the trouble call request at the call center from the telematics unit via a separate connection.

11. The medium of claim 9 , wherein the computer readable code for establishing a first connection comprises computer readable code for maintaining a communication connection transmitting the trouble call request.

12. The medium of claim 9 , wherein the computer readable code for establishing a first connection comprises computer readable code for establishing the first connection based on a determination of whether three way calling service is available.

13. The medium of claim 12 , further comprising: computer readable code for modifying the telematics unit service at the call center to temporarily provide the three-way calling service based on the determination.

14. The medium of claim 9 , further comprising: computer readable code for monitoring the second connection at the call center to troubleshoot the telematics unit.

15. A system for operating three-way calling for a telematics unit, the system comprising:

means for establishing a first connection between a call center and the telematics unit based on a trouble call request;

means for sending call instructions from the call center to the telematics unit via the first connection based on the trouble call request; and

means for establishing a second connection from the telematics unit to one of the call center or a contact-problem number associated with the trouble call request based on the call instructions; and

means for modifying telematics unit service at the call center to temporarily provide three-way calling service based on a determination of whether the three way calling service is available.

16. The system of claim 15 , further comprising: means for receiving the trouble call request at the call center from the telematics unit via a separate connection.

17. The system of claim 15 , further comprising: means for monitoring the second connection at the call center to troubleshoot the telematics unit.

18. The system of claim 15 , further comprising: means for sending termination instructions from the call center to the telematics unit via one of the first or second connection to terminate the second connection; and means for terminating the second connection based on the termination instructions.
