                   Next-Generation Pan-European eCall
                     draft-ietf-ecrit-ecall-27.txt

Abstract

   This document describes how to use IP-based emergency services
   mechanisms to support the next generation of the pan European in-
   vehicle emergency call service defined under the eSafety initiative
   of the European Commission (generally referred to as "eCall"). eCall
   is a standardized and mandated system for a special form of emergency
   calls placed by vehicles, providing real-time communications and an
   integrated set of related data.

   This document also registers MIME media types and an Emergency Call
   Additional Data Block for the eCall vehicle data and metadata/control
   data, and an INFO package to enable carrying this data in SIP INFO
   requests.

   Although this specification is designed to meet the requirements of
   European next-generation eCall, it is specified generically such that
   the technology can be re-used or extended to suit requirements across
   jurisdictions.
