Patent Images
1. A method for providing an emergency notification from a mobile vehicle communication unit to a remote human operator at a call center, comprising:
- detecting an emergency event at the vehicle, and attempting to place a data call to the call center;
in response to detecting that the attempt to place the data call has failed;
generating a human audible and human understandable emergency signal;
placing a voice call to the call center;
multiplexing the emergency signal within an audible data stream in the voice call;
transmitting the multiplexed audible data stream from the vehicle to the call center;
decoding the audible emergency signal from the audible data stream; and
audibly reproducing the extracted emergency signal to the human operator.

Abstract
The invention provides a method for inband emergency notification for voice calls by multiplexing at least one emergency signal within an audible data stream and transmitting the audible data stream from a telematic communication unit to a mobile vehicle communication system. The mobile vehicle communication system decodes the emergency signal from the audible data stream and provides an emergency service as a function of the emergency signal.
