A method for providing wireless connection capability for a telematics unit comprising:
- determining a connection failure between the telematics unit and a call center;
- retrieving an alternative cellular identifier pair from a memory in the telematics unit based on the determination;
- and
- attempting to establish a connection between the telematics unit and the call center using the alternative cellular identifier pair.
A system for providing wireless connection capability for a telematics unit comprising:
- means for determining a connection failure between the telematics unit and a call center;
- means for retrieving an alternative cellular identifier pair including an alternative mobile identification number from a memory in the telematics unit based on the determination;
- and
- means for attempting to establish a connection between the telematics unit and the call center using the alternative cellular identifier pair.
A method for providing wireless connection capability for an in-vehicle telematics unit comprising:
- determining a connection failure between the telematics unit and a call center;
- encoding control channel information with customer specific information, call specific information, and a MIN/LSN pair in response to the determined connection failure, wherein the customer specific information identifies the telematics unit to the call center and the call specific information identifies a reason for contacting the call center;
- and
- attempting to establish a connection between the telematics unit and the call center using the encoded control channel information.
