Intelligent transport systems - eSafety - Pan-European eCall operating requirements

1.1   General
The objective of implementing the pan-European in-vehicle emergency call system (eCall) is to automate the notification of a traffic accident, wherever in Europe, with the same technical standards and the same Quality of Services objectives by using a mobile telecommunication network (e.g. GSM) which supports the European pre-assigned emergency destination address (TS12 [Ref.11])(See [Ref.5, Ref.6, Ref.7, Ref.8, Ref.9]), and to provide a means of manually triggering the notification of an incident.
This European Standard defines the general operating requirements and intrinsic procedures for in-vehicle emergency call (eCall) services in order to transfer an emergency message from a vehicle to a 'Public Safety Answering Point' (PSAP) in the event of a crash or emergency, via an 'eCall' communication session and to establish a voice channel between the in-vehicle equipment and the PSAP.
NOTE 1   Private third party in-vehicle emergency supporting services may also provide a similar eCall function by other means. The provision of such services are being defined in a separate EN deliverable, and are outside the scope of this deliverable.
NOTE 2   The communications protocols and methods for the transmission of the 'eCall' message are not specified in this Standard.
NOTE 3   This European Standard determines the operating requirements for an 'eCall' service. An important part of the 'eCall' Service is a "Minimum Set of Data" (MSD). The operating requirements for the MSD are determined in this European Standard, but the form and data content of the MSD is not defined herein. A common European MSD is determined in EN 15722.
1.2   Conformance
Test requirements and conformance requirements are described in Clause 12. Conformance procedures will be specified in a separate deliverable and are outside of the scope of this European Standard.

Intelligente Transportsysteme - ESicherheit - Paneuropäische Notruf-Betriebsanforderungen

Das Ziel der Implementierung des gesamteuropäischen bordeigenen Notrufsystems (eCall) besteht darin, die Benachrichtigung über den Eintritt eines Verkehrsunfallereignisses europaweit mit denselben technischen Normen und denselben Dienstgütezielen durch Nutzung eines Mobilfunknetzes (en: Public Land Mobile Net-work, PLMN) (wie z. B. GSM oder 3G), welches die europäische zuvor zugeordnete Notzieladresse (siehe die Normativen Verweisungen) unterstützt, zu automatisieren. Zusätzlich soll ein Hilfsmittel für die manuelle Auslösung der Benachrichtigung über den Eintritt eines Notfalls zur Verfügung gestellt werden. Diese Europäische Norm legt die allgemeinen Betriebsanforderungen und intrinsischen Verfahren für fahrzeuginterne Notruf(eCall)-Dienste mit dem Ziel fest, im Falle eines Unfalls oder eines sonstigen Notfalls über eine eCall-Kommunikationssitzung einen Notruf vom Fahrzeug an eine Notrufzentrale (PSAP) zu übermitteln und eine Sprachverbindung zwischen der fahrzeugseitigen Ausrüstung und der PSAP herzustellen. ANMERKUNG 1 Von Dritten bereitgestellte, private fahrzeuginterne Dienste zur Unterstützung in Notfällen können eine ähnliche eCall-Funktion auch mit anderen Mitteln zur Verfügung stellen. Derartige Dienste sind in prEN 16102 (derzeit in der Abstimmung) festgelegt und nicht Gegenstand des vorliegenden Dokuments. ANMERKUNG 2 Die Kommunikationsprotokolle und die Verfahren für die Übertragung der eCall-Nachricht sind in der vorliegenden Norm nicht festgelegt. ANMERKUNG 3 Diese Europäische Norm legt die Betriebsanforderungen für eCall-Dienste fest. Ein wichtiger Bestand-teil des eCall-Dienstes ist der "Minimale Datensatz" (en: Minimum Set of Data, MSD). In der vorliegenden Europäischen Norm sind die Betriebsanforderungen für den MSD, nicht aber seine Form und sein Dateninhalt festgelegt. Ein gemein-samer Europäischer MSD ist in EN 15722 festgelegt.

1.1   Généralités
La mise en œuvre du système paneuropéen d’appel d’urgence à bord du véhicule (eCall) a pour objectif d’automatiser la notification d’un accident de la route, partout en Europe, avec les mêmes normes techniques et les mêmes objectifs de niveau de service en utilisant un réseau de télécommunication mobile (par exemple le GSM) qui prend en charge l’adresse de destination d’urgence pré-assignée en Europe (TS12 [Réf. 11]) (voir [Réf. 5, Réf. 6, Réf. 7, Réf. 8, Réf. 9]), et pour fournir un moyen de déclenchement manuel de notification d’un incident.
La présente Norme européenne définit les exigences de fonctionnement général et les procédures inhérentes aux services d’appel d’urgence (eCall) à bord du véhicule afin de transmettre un message d’urgence d’un véhicule à un « centre de secours compétent » (PSAP) en cas d’accident ou d’urgence, par le biais d’une session de communication d’appel d’urgence et d’établir une liaison téléphonique entre l’équipement à bord du véhicule et le PSAP.
NOTE 1   Une tierce partie privée chargée des services d’urgence à bord du véhicule peut également exercer une fonction d’appel d’urgence similaire par d’autres moyens. Les dispositions applicables à ces types de services sont en cours de définition dans une documentation EN séparée et ne relèvent pas du domaine d’application de cette documentation.
NOTE 2   Les protocoles et méthodes de communication pour la transmission des messages d’appel d’urgence ne sont pas spécifiés dans la présente Norme.
NOTE 3   La présente Norme européenne détermine les exigences de fonctionnement d’un service d’appel d’urgence eCall. Une part importante du service d’appel d’urgence est constituée par un « ensemble minimal de données » (MSD). Les exigences de fonctionnement d’un MSD sont déterminées dans la présente Nome européenne, mais la forme et le contenu des données du MSD n’y sont pas définis. Un MSD européen commun est déterminé dans l’EN 15722.

EN 16072:2011 (E) 5 Introduction The scale of death and injury on roads in Europe needs to be fully comprehended to understand the need for 'Emergency Call' (eCall). In 2008 there were 38 900 fatalities in EU-27. The figure for 2009 is around 34 500 fatalities. The trend 2001 to 2008 is around 5 % reduction annually. Road accident injuries are in the region of 1,7 million (2008). Roads remain unsafe and further efforts are needed. The pan-European in-vehicle emergency call, eCall, is estimated to have the potential to save up to 2 500 fatalities annually in EU-27 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 (EU-15). 65 % 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 'Road Traffic and Transport Telematics' (otherwise known as 'Intelligent Transport Systems' or 'ITS'), can be described as an 'automatic or user instigated system to provide notification to Public Safety Answering Points (PSAP), by means of wireless communications, that a vehicle has crashed, and to provide coordinates, 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 (TS12) services. Definition of the Minimum Set of Data, the communications media and means of transferring the data are not specified in this European Standard. This European Standard specifies the generic operational requirements for the provision of an eCall service. The practical provision and operation of eCall service and equipment is dependent on the communications medium being available throughout the lifetime of equipment installed in vehicles. NOTE The term PSAP, which is most widely used in the eCall documentation, European Commission documents etc., equates to the term emergency call response centre. The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this European Standard may involve the use of patents concerning eCall given in this European Standard. CEN takes no position concerning the evidence, validity and scope of these patent rights. SIST EN 16072:2011
