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.

Introduction

This document describes tests that verify on-board unit (OBU) conformance of functions and data

structures implementations for electronic fee collection (EFC) applications.
The purpose of this document is to define tests that:
— assess OBU capabilities,
— assess OBU behaviour,
— serve as a guide for OBU conformance evaluation and type approval,

— achieve comparability between the results of the corresponding tests applied in different places at

different times, and
— facilitate communications between parties.

Part 2:
Conformance test for the on-board unit application
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.

---------------------- Page: 17 ----------------------
SIST EN ISO 14907-2:2021
ISO 14907-2:2021(E)

— ICS according to 5.2. The ICS shall include statements regarding the following:

— L7 services that are implemented in the OBU;
— EFC functions (action types) that are implemented in the OBU;
— whether or not data elements are used;
— IXIT according to 5.3 The IXIT shall, if applicable, include:

— a statement regarding which L2 services shall be used to transfer the L7 services (and EFC

services);

— a description of security calculations in the OBU including a specification of the encryption

algorithm used;

— values of the test master keys for calculation and verification of OBU security data such as

authenticators and access credentials.

The supplier should also provide configuration/personalization equipment for the OBU if this ensures

effective testing.

Figure 1 gives a more detailed picture of the interface between the entity performing the conformance

test and the supplier of the DUT. By the EFC application specification, the ICS proforma and the IXIT

proforma, the supplier is requested to provide the DUT (OBU), which contains the implementation

under test (IUT), as well as the documentation needed to perform the tests. More details on the content

of the different documents are given in Clause 5 on OBU and supporting information.

NOTE The DUT contains the IUT.

Figure 1 shows the overall procedure of conformance testing. Figure 2 shows the exchange of

information between the supplier of the DUT and the test house.

5.2 ICS

The ICS is a statement made by the supplier that claims conformance to a certain specification. The ICS

states which capabilities have been implemented in the specifications. It also states possible limitations

in the implementation of the specification.

This document describes testing of implementations according to the following documents:

— EN 12834;
— ISO 14906.
Annex A contains the ICS proforma that shall be used for the ICS.
5.3 IXIT

The IXIT is a statement made by the supplier or an implementer of an IUT which contains or references

all of the information, in addition to that given in the ICS, related to the DUT and its testing environment.

The IXIT enables the test laboratory to run an appropriate test suite against the DUT.

In this document, the IXIT specifies the services in the lower communication layers that shall be used to

perform the services to be tested. These services are described in EN 12795, EN 12253 and EN 13372,

for example.

The IXIT shall also contain further information and describe algorithms and procedures that are not

specified in the above listed documents but are prerequisites to perform the testing. Examples of such

information are:
— content of the ApplicationContextMark in the VST,
— calculation of access credentials in DSRC services,
— use of returnCode in DSRC L7 services and EFC functions, and
— calculation of authenticators in EFC functions.

Annex B contains the IXIT proforma that shall be used for the declaration of the IXIT.

6 Testing requirements
6.1 EFC application interface

Figure 3 illustrates the scope of the conformance assessment of the EFC application interface covered

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 APs.

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 AP. 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 eve
