Next-Generation Pan-European eCall
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
Data Type 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
next-generation Pan-European eCall (NG-eCall), it is specified
generically such that the technology can be reused or extended to
suit requirements across jurisdictions.
