Abstract

The invention provides a method of reestablishing wireless communications for a mobile vehicle. After a communication link failure on a first communication link is detected, it is determined whether to reconnect on the first communication link based on at least one communication condition factor, and then an attempt is made to establish a second communication link based on the communication condition factor determination.

Claims

1. A method of reestablishing wireless communications for a mobile vehicle, comprising:

detecting a communication link failure on a first communication link;

determining whether to reconnect on the first communication link based on at least one communication condition factor; and

attempting to establish a second communication link based on the communication condition factor determination.

2. The method of claim 1 wherein the first communication link is one of an analog cellular call or a digital cellular call.

3. The method of claim 1 wherein the second communication link is selected from the group consisting of an analog cellular call, a digital cellular call, a short message service transmission, a data transmission over an Internet protocol, and a voice transmission over an Internet protocol.

4. The method of claim 1 wherein the at least one communication condition factor is selected from a group consisting of a velocity of the mobile vehicle, a geographical location of the mobile vehicle, an availability of digital coverage, an availability of analog coverage, a criticality assessment of information to be communicated, an assessment of a type of data communicated, a call basis, a delay impact assessment, a reconnect attempt elapsed time, and a reconnect attempt elapsed number.

5. The method of claim 1 further comprising:

determining a link failure type of the first communication link; and

determining whether to reconnect on the first communication link based on the link failure type.

6. The method of claim 5 wherein the link failure type is selected from a group consisting of a bit-error rate failure, a frame-error rate failure, a critical data transmission failure, an interim data transmission failure, and a voice transmission failure.

7. The method of claim 1 further comprising:

adjusting at least one wireless system setting based on the communication link failure; and

establishing a communication link with the adjusted wireless system setting.

8. The method of claim 1 further comprising:

providing a reconnect attempt time period to establish the second communication link.

9. The method of claim 1 further comprising:

providing a reconnect attempt number limit to establish the second communication link.

10. A computer usable medium including a program to reestablish wireless communications for a mobile vehicle, comprising:

computer program code to detect a communication link failure on a first communication link;

computer program code to determine whether to reconnect on the first communication link based on at least one communication condition factor; and

computer program code to attempt to establish a second communication link based on the communication condition factor determination.

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

computer program code to determine a link failure type of the first communication link; and

computer program code to determine whether to reconnect on the first communication link based on the link failure type.

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

computer program code to adjust at least one wireless system setting based on the communication link failure; and

computer program code to establish a communication link with the adjusted wireless system setting.

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

computer program code to provide a reconnect attempt time period to establish the second communication link.

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

computer program code to provide a reconnect attempt number limit to establish the second communication link.

15. A system for reestablishing wireless communications for a mobile vehicle, comprising:

means for detecting a communication link failure on a first communication link;

means for determining whether to reconnect on the first communication link based on at least one communication condition factor; and

means for attempting to establish a second communication link based on the communication condition factor determination.

16. The system of claim 15 further comprising:

means for determining a link failure type of the first communication link; and

means for determining whether to reconnect on the first communication link based on the link failure type.

17. The system of claim 15 further comprising:

means for adjusting at least one wireless system setting based on the communication link failure; and

means for establishing a communication link with the adjusted wireless system setting.

18. The system of claim 15 further comprising:

means for providing a reconnect attempt time period to establish the second communication link.

19. The system of claim 15 further comprising:

means for providing a reconnect attempt number limit to establish the second communication link.
