Abstract

The invention provides a method of transitioning between voice and data communications with a mobile vehicle. A switch-to-voice command signal is sent from a call center modem pool to the mobile vehicle, and a vehicle switch-to-voice acknowledgement signal is received at the call center. A call from the call center modem pool is switched to a call center advisor in response to the vehicle switch-to-voice acknowledgement signal.

Claims

1. A method of transitioning between voice and data communications with a mobile vehicle, comprising:

sending a switch-to-voice command signal from a call center modem pool to the mobile vehicle;

receiving a vehicle switch-to-voice acknowledgement signal at the call center;

switching a call from the call center modem pool to a call center advisor in response to the vehicle switch-to-voice acknowledgement signal; and

entering a voice-ready mode at the mobile vehicle when a predetermined delay period has elapsed after the vehicle switch-to-voice acknowledgement signal has been sent.

2. The method of claim 1 wherein the voice-ready mode comprises an un-muted audio signal.

3. A computer usable medium including a program for transitioning between voice and data communications with a mobile vehicle, comprising:

computer program code to send a switch-to-voice command signal from a call center modem pool to the mobile vehicle;

computer program code to receive a vehicle switch-to-voice acknowledgement signal at the call center;

computer program code to switch a call from the call center modem pool to a call center advisor in response to the vehicle switch-to-voice acknowledgement signal; and

computer program code to enter a voice-ready mode at the mobile vehicle when a predetermined delay period has elapsed after the vehicle switch-to-voice acknowledgement signal has been sent.

4. A system for transitioning between voice and data communications with a mobile vehicle, comprising:

means for sending a switch-to-voice command signal from a call center modem pool to the mobile vehicle;

means for receiving a vehicle switch-to-voice acknowledgement signal at the call center;

means for switching a call from the call center modem pool to a call center advisor in response to the vehicle switch-to-voice acknowledgement signal; and

means for entering a voice-ready mode at the mobile vehicle when a predetermined delay period has elapsed after the vehicle switch-to-voice acknowledgement signal has been sent.
