eCall library for Open AT

eCall is a pan-European emergency call either generated manually by vehicle occupants or automatically via activation of in-vehicle sensors when an accident occurs. When activated, the in-vehicle eCall system establishes a 112-voice connection directly with the relevant PSAP (Public Safety Answering Point). At the same time, a minimum set of data (MSD) – including key information about the accident such as time, location and vehicle description – is sent via the InBand modem technology as standardized by 3GPP to the PSAP operator receiving the voice call.

The APIs provided with this Library are an abstraction layer to the core in-vehicle system modem functionality of the eCall InBand Modem. Using these APIs, the eCall Application can send MSD data over voice call either initiated by the vehicle application or by the PSAP server.

Key benefits:

• Real time and robust library
  • Plug-In processing scheduled by 20ms period audio interrupts
  • All time critical transitions (e.g. 2s timeout) managed by Plug-In library
  • Static memory allocation
• Simple eCall application design
  • No real time constraints on application once emergency call is initiated
  • Reduced API set : open, push request, close
  • Audio mute/unmute managed by Plug-In library
• Application maintains control
  • Application is notified of every internal state change for easy monitoring / improved user interface
  • Emergency call is under application control
  • In-Band Modem can be stopped at any time
