Intelligent transport systems - ESafety - Pan-European eCall operating requirements
SIST EN 16072:2025

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), which supports the European pre-assigned emergency destination address (see normative references) and to provide a means of manually triggering the notification of an incident.
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 and to establish a voice channel between the in-vehicle equipment and the PSAP.
Private third party in-vehicle emergency supporting services can 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 document.
The communications protocols and methods for the transmission of the MSD are not specified in this document.
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 document, but the form and data content of the MSD is not defined herein. A common European MSD is determined in EN 15722.
This document does not specify whether eCall is provided using embedded equipment or other means (for example in the case of aftermarket equipment).

Electronic fee collection - Evaluation of on-board and roadside equipment for conformity to ISO 12813 (ISO 13143:2025)

This document specifies the test suite structure (TSS) and test purposes (TPs) for evaluating the conformity of on-board equipment (OBE) and roadside equipment (RSE) to ISO 12813.
It provides a basis for conformance tests for dedicated short-range communication (DSRC) OBE and RSE to support interoperability between different equipment supplied by different manufacturers.
ISO 12813 specifies requirements for the compliance check communication (CCC) interface level, but not for the OBE or RSE internal functional behaviour. Consequently, tests regarding OBE and RSE functional behaviour remain outside the scope of this document.

This document specifies a unified logical data model based on available existing dynamic information standards. The data has precise relative location references to be linked with ISO/TS 22726-1 which specifies the architecture and the logical data model of static map data for connected and automated driving applications. Dynamic event data comes from external systems and has been defined and specified independently by existing standards. Therefore, the logical data model in this document is formed to synthesize contents referring to other standards.

Electronic fee collection - Localization augmentation communication for autonomous systems (ISO 13141:2024)
SIST EN ISO 13141:2024

This document establishes requirements for short-range communication for the purposes of augmenting the localization in autonomous electronic fee collection (EFC) systems. Localization augmentation serves to inform on-board equipment (OBE) about geographical location and the identification of a charge object. This document specifies the provision of location and heading information and security means to protect against the manipulation of the OBE with false RSE.
The localization augmentation communication (LAC) takes place between an OBE in a vehicle and fixed RSE. This document is applicable to OBE in an autonomous mode of operation.
This document specifies attributes and functions for the purpose of localization augmentation, by making use of the dedicated short-range communications (DSRC) communication services provided by DSRC Layer 7, and makes these LAC attributes and functions available to the LAC applications at the RSE and the OBE. Attributes and functions are specified on the level of application data units (ADUs; see Figure 1).
As depicted in Figure 1, this document is applicable to:
—     the application interface definition between OBE and RSE;
—     the interface to the DSRC application layer, as specified in ISO 15628 and EN 12834;
—     the use of the DSRC stack.
The LAC is suitable for a range of short-range communication media. This document provides specific definitions regarding the CEN-DSRC stack as specified in EN 15509. Annexes C, D, E and H provide for the use of the Italian DSRC as specified in ETSI/ES 200 674-1, ISO CALM IR ARIB DSRC and WAVE DSRC.
This document contains a protocol implementation conformance statement (PICS) proforma in Annex B and transaction examples in Annex F. Annex G highlights how to use this document for the European Electronic Toll Service (EETS).
Test specifications are not within the scope of this document.

Electronic fee collection - Compliance check communication for autonomous systems (ISO 12813:2024)
SIST EN ISO 12813:2024

This document specifies requirements for short-range communication for the purposes of compliance checking in autonomous electronic fee collecting systems. Compliance checking communication (CCC) takes place between a road vehicle's on-board equipment (OBE) and an interrogator [fixed and mobile roadside equipment (RSE) or hand-held unit] and serves to establish whether the data that are delivered by the OBE correctly reflect the road usage of the corresponding vehicle according to the rules of the pertinent toll regime.
The operator of the compliance checking interrogator is assumed to be part of the toll charging role as defined in ISO 17573-1. The CCC permits identification of the OBE, vehicle and contract, and verification of whether the driver has fulfilled their obligations and the checking status and performance of the OBE. The CCC reads, but does not write, OBE data.
This document is applicable to OBE in an autonomous mode of operation. It is not applicable to compliance checking in dedicated short-range communication (DSRC)-based charging systems.
It specifies data syntax and semantics, but not a communication sequence. All the attributes specified herein are required in any OBE claimed to be compliant with this document, even if some values are set to “not specified” in cases where a certain functionality is not present in an OBE. The interrogator is free to choose which attributes are read in the data retrieval phase, as well as the sequence in which they are read. In order to achieve compatibility with existing systems, the communication makes use of the attributes specified in ISO 17573-3 wherever useful.
The CCC is suitable for a range of short-range communication media. Specific definitions are given for the CEN-DSRC as specified in EN 15509, as well as for the use of ISO CALM IR, the Italian DSRC as specified in ETSI ES 200 674-1, ARIB DSRC, and WAVE DSRC as alternatives to the CEN-DSRC. The attributes and functions specified are for compliance checking by means of the DSRC communication services provided by DSRC application layer, with the CCC attributes and functions made available to the CCC applications at the RSE and OBE. The attributes and functions are specified on the level of application data units (ADUs).
The definition of the CCC includes:
—     the application interface between OBE and RSE (as depicted in Figure 2);
—     use of the generic DSRC application layer as specified in ISO 15628 and EN 12834;
—     CCC data type specifications given in Annex A;
—     a protocol implementation conformance statement (PICS) proforma is given in Annex B;
—     use of the CEN-DSRC stack as specified in EN 15509, or other equivalent DSRC stacks as described in Annex C, Annex D, Annex E and Annex F;
—     security services for mutual authentication of the communication partners and for signing of data (see Annex H);
In addition, an example CCC transaction is presented in Annex G and Annex I highlights how to use this document for the European Electronic Toll Service (EETS).
Test specifications are not within the scope of this document.

NOTE    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 PLMN (such as ETSI prime medium) which supports the European harmonized 112/E112 emergency number (TS12 ETSI TS 122 003 or IMS packet switched network) and to provide a means of manually triggering the notification of an emergency incident.
