Emergency calls made by in-vehicle systems (e.g., automatically in the event of a crash or serious incident or manually by a vehicle occupant) assist in significantly reducing road deaths and injuries by allowing emergency services to respond quickly and appropriately to the specifics of the incident, often with better location accuracy.

            Next-Generation Vehicle-Initiated Emergency Calls


   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    Data Type for the vehicle, sensor, and location data (often referred    to as "crash data" even though there is not necessarily a crash) and    an INFO package to enable carrying this and related data in SIP INFO    requests.  An external specification for the data format, contents,    and structure is 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 (IVSs) 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 it adds attribute values to the metadata/control    object to permit greater functionality.  This document registers a    new 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.
