European foreword
This document (EN 15722:2020) has been prepared by Technical Committee CEN/TC 278 “Intelligent
transport systems”, the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2021, and conflicting national standards shall
be withdrawn at the latest by February 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15722:2015.
In comparison with the previous edition, the following modifications have been made:
— Correction of some typing errors;
— Added additional clarifications to solve frequently asked questions;
— Inclusion of recent locations mandatory to support more efficient dispatch of emergency services;
— MSD field “numberOfPassengers” replaced by “numberOfOccupants”;
— The number of vehicle categories supported by this standard has been expanded through revision of
the enumeration values to enable support for additional categories of vehicles, which now covers the
full UNECE categorization;
— Updated privacy requirements to include EU 2016/679 GDPR.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
The pan-European in-vehicle emergency call, 'eCall', is estimated to have the potential to save up to 2 500
fatalities annually in the EU when fully deployed, and furthermore to reduce the severity of injuries, to
bring significant savings to the society in and to reduce human suffering.
Emergency calls made from vehicles or mobile telephones using wireless technologies, can assist with
the objectives of significantly reducing road deaths and injuries, but drivers often have poor (imprecise)
location awareness, especially on interurban roads or abroad. Additionally, in many situations the car
occupants may not be in a position to call using a normal mobile phone.
The situation is worse for those travelling abroad. A high (and increasing) number of vehicles travelling
outside their home country is thus also contributing to the need for automated emergency call system in
vehicles. In EU there are over 100 million trips to another EU country per year, 65 % of the people feel
less protected while abroad and most do not know which number to call in an emergency (in some
countries over 60 %). Language problems are pertinent and may render proper communication difficult.
Yet, in the most crucial cases, the victim(s) may not be able to call because they have been
injured/trapped, do not know the local number to call, and in many cases, particularly in rural situations
and late at night, there may be no witnesses who happen to have a mobile phone and a sense of
community.
eCall, in the context of "Intelligent Transport Systems" or "ITS", (previously known as "Road Traffic and
Transport Telematics") can be described as a "user instigated or automatic system to provide notification
to public safety answering points, by means of wireless communications, that a vehicle has crashed, and
to provide coordinates and a defined minimum set of data, and where possible a voice link to the PSAP”.
The objective of implementing the pan-European in-vehicle emergency call system (eCall) is to automate
the notification of a traffic accident, wherever in the European Union and associated countries, with the
same technical standards and the same quality of services objectives of other emergency services (for
example the TS12 emergency call of GSM/UMTS).
This document specifies the "Minimum Set of Data" (MSD) to be transferred by such an in-vehicle eCall
system in the event of a crash or emergency.
NOTE The communications media and means of transferring the eCall MSD are not defined in this document.
See list of referenced standards.
1 Scope
This document specifies the standard data concepts that comprise the "Minimum Set of Data" (MSD) to
be transferred from a vehicle to a 'Public Safety Answering Point' (PSAP) in the event of a crash or
emergency via an 'eCall' communication transaction.
Optional additional data concepts may also be transferred as part of the MSD.
The communications media protocols and methods for the transmission of the eCall message are not
specified in this document.
