Method and system for inband emergency notification for voice calls |
摘要 |
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.
