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. 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.
