Qualcomm and Hughes Telematics have successfully demonstrated the data transmission technology of the upcoming pan-European, in-vehicle emergency call (eCall) standard over commercial wireless networks at the 12th eSafety Forum Plenary meeting, “eCall Summit”, held in Brussels, Belgium on October 29, 2009.
The creation of eCall standards and requirements has been triggered by the eSaftety Forum, an initiative of the relevant stakeholders, brought together by the European Commission.
An eCall is generated either manually by vehicle occupants, or automatically via activation of in-vehicle sensors, in the case when an accident occurs. When activated, the eCall-enabled, in-vehicle system establishes a 112-voice connection directly with the relevant Public Safety Answering Point (PSAP). At the same time, a Minimum Set of Data- including key information about the accident such as time, location and vehicle description – is sent to the PSAP operator receiving the voice call.
Technology provided by HTI and Qualcomm, including an eCall in-band modem, was used to make a call to a prototype of an eCall-enabled PSAP located in Germany. Once the voice call was established, the eCall in-band modem protocol was used to transmit the Minimum Set of Data to the PSAP. The eCall modem was fully integrated on the Qualcomm QSC6270 chipset embedded in the demonstration unit.
