1. A method for reestablishing wireless communications from a mobile vehicle to a call center, the method comprising:
- receiving a trigger;
initiating a first communication attempt over a first communication link with a call center based on the trigger;
detecting a communication link failure;
determining at least one communication condition factor based on the failure;
determining at least one link failure type based on the failure;
determining whether to reconnect with the call center over the first communication link or a second communication link based on the at least one communication condition factor and at least one link failure type; and
initiating a second communication attempt over either the first communication link or second communication link based on the determination.

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.
