A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Emergency Context Resolution with Internet Technologies of the IETF.

        Title           : Next-Generation Vehicle-Initiated Emergency Calls
        Authors         : Randall Gellens

   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 media type and 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) and a SIP INFO package to enable carrying this
   and related data in SIP INFO requests.  An external specification for
   the data format, contents, and structure are referenced in this

   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 use of 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 IETF eCall document, with the primary differences
   being that this document makes the MSD data set optional and VEDS
   mandatory, and adds attribute values to the metadata/control object
   to permit greater functionality.  This document registers a new SIP
   INFO package (identical to that registered for eCall but with the
   addition of the VEDS MIME type).  This document also describes legacy
   (circuit-switched) ACN systems and their migration to next-generation
   emergency calling, to provide background information and context.
