This European Standard shall be given the status of a national standard, either by publication
17、of an identical text or by endorsement, at the latest by October 2015, and conflicting national standards shall be withdrawn at the latest by October 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall n
18、ot be held responsible for identifying any or all such patent rights. This document supersedes EN 15722:2011. This revision is designed to solve ambiguities, provide clarity and improve consistency throughout the document. A significant part of Clause 6 has been reformatted, some parts have been rew
19、ritten. None of the proposed changes breaks compatibility with the superseded version. The ASN.1 specifications have been updated to the current most efficient options. Subclause 6.1 now completely describes the information around the concepts, formats and data-encoding, directly relating it to the
20、chosen encoding rules (ASN.1 UPER). The table describing the components of the MSD (6.2) has been revised. The rationale behind this was to remove inconsistencies between the encoding rules and the description. Comments made by Member States have been incorporated. Removed reference to the number of
21、 Member States of the European Union. The ASN.1 definition of the MSD has been revised and updated. A syntax check result has been added. An example message with its UPER encoding was also added. Specification of the concept of a data registry to which the oid data element refers, and an explanatory
22、 Annex (E) explaining the concept of OIDs to has been added. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia

24、015 (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 the EU Member States. The provisional figure for 2009 is around 34 500 fatalities. The trend 2001-2008 i
25、s around 5 % reduction annually. Road accident injuries are in the region of 1,7 million (2007). 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 the EU when fully dep
26、loyed, 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 injur
27、ies, 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) numb
28、er 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
29、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, par
30、ticularly 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 instigate
31、d 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
32、 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
33、GSM/UMTS). This European Standard 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 European Standard. See list of referenc
34、ed Standards. BS EN 15722:2015EN 15722:2015 (E) 6 1 Scope This European Standard 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 communicati
35、on transaction. Optional additional data concepts may also be transferred. The communications media protocols and methods for the transmission of the eCall message are not specified in this European Standard. 2 Normative references The following documents, in whole or in part, are normatively refere

48、most appropriate services to the crash or emergency site and to speed up the response. The minimum set of data makes it possible for the PSAP operator to respond to the eCall even without the voice connection. The “Minimum Set of Data“ shall be a direct, timely message to the PSAP operator receiving
49、 the emergency call. The information elements in the MSD have been selected on the basis of their relevance in an emergency rescue situation.
