           Next-Generation Vehicle-Initiated Emergency Calls
                   draft-ietf-ecrit-car-crash-05.txt

Abstract

   This document describes how to use IP-based emergency services
   mechanisms to support the next generation of emergency calls placed
   by vehicles (automatically in the event of a crash or serious
   incident, or manually invoked by a vehicle occupant) and conveying
   vehicle, sensor, and location data related to the crash or incident.
   Such calls are often referred to as "Automatic Crash Notification"
   (ACN), or "Advanced Automatic Crash Notification" (AACN), even in the
   case of manual trigger.  The "Advanced" qualifier refers to the
   ability to carry a richer set of data.

   This document also registers a MIME Content Type and an Emergency
   Call Additional Data Block for the vehicle, sensor, and location data
   (often referred to as "crash data" even though there is not
   necessarily a crash).  An external specification for the data format,
   contents, and structure are referenced in this document.

   This document reuses the technical aspects of next-generation pan-
   European eCall (a mandated and standardized system for emergency
   calls by in-vehicle systems within Europe and other regions).
   However, this document specifies a different set of vehicle (crash)
   data, specifically, the Vehicle Emergency Data Set (VEDS) rather than
   the eCall Minimum Set of Data (MSD).  This document is an extension
   of the eCall document, with the differences being that this document
   makes the MSD data set optional and VEDS mandatory.  This document
   also discusses legacy (curcuit-switched) ACN systems and their
   migration to next-generation emergency calling.
