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-28 when fully deployed and furthermore to reduce the severity of injuries, to bring significant

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

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

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

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.

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.

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 'Public Land Mobile Networks'(PLMN) (such as GSM and UMTS),

which supports the European pre-assigned emergency destination address (see normative references)

This document specifies 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

Private third party in-vehicle emergency supporting services may also provide a similar eCall function by

other means. The provision of such services are defined in EN 16102, and are outside the scope of this

This document specifies 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
