Remote vehicle data access during a multi-way call with a vehicle telematics unit
First Claim
1. A method of obtaining vehicle data during a multi-way call involving a vehicle telematics unit, call center, and at least one third party, comprising the steps of:
- conducting a multi-way voice call involving at least three different phone terminal units which include a vehicle telematics unit, a call center terminal, and a third party terminal, wherein the multi-way voice call involves a telephone connection to the telematics unit and a telephone connection to the third party terminal;
separating the multi-way voice call into a two-way call and a second multi-way call, wherein the two-way call is switched from a voice transmission mode to a data transition mode when vehicle data is sent between the call center and the vehicle telematics unit while maintaining voice communications between the call center and the third party;
receiving, at a data receiver, vehicle data sent from the telematics unit over the two-way call; and
ending the two-way call with the data receiver and reconnecting the telematics unit to the multi-way voice call without ending the telephone connection to the telematics unit.

Abstract
A system and method for obtaining data during a multi-way call involving at least a vehicle telematics unit, call center, and third party such as a public safety answering point (PSAP). While connected together in at least a three-way voice call, the connection from the telematics unit is switched out of the call and connected to a data modem to receive vehicle data uploaded from the telematics unit. This can be used to provide vehicle location and other vehicle information such as current vehicle conditions and operational state. Thereafter, the telematics unit connection is switched back into the multi-way call to permit continued voice communications between the parties. The uploaded vehicle data can then be used by the call center or PSAP to provide emergency or other assistance.
