Internet Engineering Task Force (IETF) R. Gellens Request for Comments: 8147 Core Technology Consulting Category: Standards Track H. Tschofenig ISSN: 2070-1721 Individual May 2017 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.
