Electronic fee collection - Test procedures for user and fixed equipment - Part 2: Conformance test for the on-board unit application interface (ISO 14907-2:2021)

This document describes tests which verify on-board unit (OBU) conformance of functions and data
structures implementations, as defined in the implementation conformance statement (ICS) based on
ISO 14906 for EFC applications.
This document defines tests for assessing OBU conformance in terms of :
— basic dedicated short-range communication (DSRC) L7 functionality,
— EFC application functions,
— EFC attributes (i.e. EFC application information),
— the addressing procedures of EFC attributes and (hardware) components,
— the EFC transaction model, which defines the common elements and steps of any EFC transaction, and
— the behaviour of the interface so as to support interoperability on an EFC-DSRC application
interface level.
After the tests of isolated data items and functions (C.2 to C.4), an example is given for testing a
complete EFC transaction (C.3). Although this document defines examples of test cases for DSRC
and EFC functionality (see Annex C), it does not intend to specify a complete test suite for a certain
implementation. To compose a test suite for a specific EFC implementation, the test cases can be
modified and new test cases can be defined and added in order for the conformance test suite to be
complete. It can be useful to consider the following when defining a complete test suite:
— small range: “exhaustive testing” of critical interoperability/compatibility features,
— large range: testing of boundaries and random values, and
— composite types: testing of individual items in sequence or parallel.
This document does not define tests which assess:
— performance,
— robustness, and
— reliability of an implementation.
NOTE 1 ISO 14907-1 defines test procedures that are aimed at assessing performance, robustness and
reliability of EFC equipment and systems.
NOTE 2 The ISO/IEC 10373 series defines test methods for proximity, vicinity, integrated circuit(s) cards and
related devices that can be relevant for OBUs which support such cards.
Annex D provides an informative overview of Japanese on-board equipment (OBE) conformance tests
which are based on the ISO 14907 series, in order to illustrate how these can be applied in practice.

Perception du télépéage - Modes opératoires relatifs aux équipements embarqués et aux équipements fixes - Partie 2: Essai de conformité de l'interface d'application de l'unité embarquée (ISO 14907-2:2021)

Le présent document décrit les essais permettant de vérifier la conformité de l’unité embarquée en termes de réalisations des fonctions et des structures de données, selon ce qui est défini dans la déclaration de conformité d’une mise en œuvre sur la base de l’ISO 14906 pour les applications de perception électronique du télépéage.
Ce document définit des essais permettant d’évaluer la conformité de l’unité embarquée en ce qui concerne:
—    la fonctionnalité L7 de la communication dédiée à courte portée (DSRC) de base;
—    les fonctions de l’application de perception du télépéage (EFC);
—    les attributs EFC (à savoir des informations sur les applications EFC);
—    les procédures d’adressage des attributs EFC et des composants (matériels);
—    le modèle de transaction EFC, qui définit les éléments et les étapes que toutes les transactions ont en commun; et
—    le comportement de l’interface chargée de prendre en charge l’interopérabilité à un niveau donné d’interface d’application EFC-DSRC.
Après les essais des fonctions et des éléments de données isolés (C.2 à C.4), un exemple est donné pour les essais d’une transaction EFC complète (C.3). Alors que le présent document définit (voir Annexe C) des exemples de cas d’essai pour les fonctionnalités DSRC et EFC, il ne vise pas à spécifier une batterie d’essais complète appliquée à une réalisation donnée. Pour composer une batterie d’essais pour une implémentation spécifique de l’EFC, les cas d’essai peuvent être modifiés et de nouveaux cas d’essai peuvent être définis et ajoutés afin que la batterie d’essais de conformité soit complète. Il peut être utile de tenir compte des éléments suivants pour définir une batterie d’essais complète:
—    gamme d’essais restreinte: «essais exhaustifs» des caractéristiques critiques d’interopérabilité et de compatibilité;
—    large gamme d’essais: essais aux limites et pour des valeurs aléatoires; et
—    types composites: essais d’éléments individuels en séquence ou en parallèle.
Ce document n’a pas pour objet de définir des essais permettant d’évaluer:
—    les performances,
—    la robustesse et
—    la fiabilité d’une réalisation.
NOTE 1      L’ISO 14907-1 définit des procédures d’essais qui visent à évaluer les performances, la robustesse et la fiabilité des équipements et systèmes de télépéage.
NOTE 2      La série ISO/IEC 10373 définit des méthodes d’essai pour les cartes à circuit(s) intégré(s) de proximité ou de voisinage et les dispositifs connexes qui peuvent être importants pour les unités embarquées prenant en charge de telles cartes.
L’Annexe D donne un aperçu informatif des essais de conformité des équipements embarqués japonais qui reposent sur la série ISO 14907, afin de montrer comment ceux-ci peuvent être appliqués dans la pratique.

interface
1 Scope
This document describes tests which verify on-board unit (OBU) conformance of functions and data
structures implementations, as defined in the implementation conformance statement (ICS) based on
ISO 14906 for EFC applications.
This document defines tests for assessing OBU conformance in terms of :
— basic dedicated short-range communication (DSRC) L7 functionality,
— EFC application functions,
— EFC attributes (i.e. EFC application information),
— the addressing procedures of EFC attributes and (hardware) components,
— the EFC transaction model, which defines the common elements and steps of any EFC transaction, and
— the behaviour of the interface so as to support interoperability on an EFC-DSRC application
interface level.
After the tests of isolated data items and functions (C.2 to C.4), an example is given for testing a
complete EFC transaction (C.3). Although this document defines examples of test cases for DSRC
and EFC functionality (see Annex C), it does not intend to specify a complete test suite for a certain
implementation. To compose a test suite for a specific EFC implementation, the test cases can be
modified and new test cases can be defined and added in order for the conformance test suite to be
complete. It can be useful to consider the following when defining a complete test suite:
— small range: “exhaustive testing” of critical interoperability/compatibility features,
— large range: testing of boundaries and random values, and
— composite types: testing of individual items in sequence or parallel.
This document does not define tests which assess:
— performance,
— robustness, and
— reliability of an implementation.
NOTE 1 ISO 14907-1 defines test procedures that are aimed at assessing performance, robustness and
reliability of EFC equipment and systems.
NOTE 2 The ISO/IEC 10373 series defines test methods for proximity, vicinity, integrated circuit(s) cards and
related devices that can be relevant for OBUs which support such cards.

DRAFT INTERNATIONAL STANDARD ISO/DIS 14907-2:2020(E)

Electronic fee collection — Test procedures for user and fixed
equipment — Part 2: Conformance test for the on-board unit
application interface
1 Scope
This document describes tests that verify on-board unit (OBU) conformance of implementations of
functions and data structures, as defined in the implementation conformance statement based on
ISO 14906 for electronic fee collection (EFC) applications.
It defines tests for assessment of OBU conformance in terms of :
— basic dedicated short-range communication (DSRC) L7 functionality,
— EFC application functions,
— EFC attributes (i.e. EFC application information),
— the addressing procedures of EFC attributes and (hardware) components,
— the EFC transaction model, which defines the common elements and steps of any EFC transaction,
and
— the behaviour of the interface so as to support interoperability on an EFC-DSRC application interface
level.
After the tests of isolated data items and functions (C.2 to C.4), an example is given for testing of a
complete EFC transaction (C.3).
Whereas this document defines examples of test cases for DSRC and EFC functionality in Annex C, it does
not intend to specify a complete test suite for a certain implementation. To compose a test suite for a
specific EFC implementation, the test cases may have to be modified and new test cases may have to be
defined and added for the conformance test suite to be complete. It can be useful to consider the following
when defining a complete test suite:
— small range: “exhaustive testing” of critical interoperability/compatibility features,
— large range: testing of boundaries and random values, and
— composite types: testing of individual items in sequence or parallel.
It is outside the scope of this document to define tests that assess
— performance,
— robustness, and
— reliability of an implementation.

by this document.

Figure 3 — The EFC application interface
6.2 Conceptual test architecture
A remote test method shall be used for the conformance test of OBUs (DUT). Figure 4 shows the
conceptual testing architecture of tester and DUT. The conformance test is only related to the the PoC,
which is the point where the test events are controlled. The PoC shall be implemented inside the tester
on the interface between the application layer and the application process.
The point of observation PoO, which is the point where the occurrence of test events is to be observed,
shall be implemented inside the tester on the interface between the application layer and the application
process. The PoO must also interface the data link layer since some tests require observation of the
behaviour on this layer.
The PoC and PoO are characterized by a set of application service primitives ASPs, according to the
specifications of the tests. The test events observed at the PoO may be supplemented by information
provided by other sub-units, e.g. MMI or an IC card if available with the DUT.
