Electronic fee collection - Evaluation of equipment for conformity to ISO/TS 17575-2 - Part 1: Test suite structure and test purposes (ISO/TR 16401-1:2018)

This document covers the test purposes for Front End Communications API covering functionalities
related to instance handling, session handling, communication service primitives (i.e.
sending/receiving of ADUs) and visible state transitions. It covers EFC communication services
described in ISO 17575-2:2016, Clause 5 and PICS proforma in ISO 17575-2:2016, B.2. Claims related to
Front End storage capacity are out of scope of this document.
This document covers the test purposes for Front End Application related to session establishment on
Back End request and related to session re-establishment when session requested by Back End failed.
There are no other claims with respect to Front End Application described in ISO 17575-2.
The underlying communication technology requirements for layer 1 to 4 specified in ISO 17575-2:2016,
Clause 6 are out of scope of this document.
Similarly, Back End Communications API is out of scope of this document. According to ISO 17575-2
it is expected that these Front End Communications API will be “reflected” in the BE; however, BE
Communications API is out of scope of ISO 17575-2.
Test purposes have been organized into the test suite groups, designated for the Front End
Communications API and Front End Application, respectively.
Aside from the test purposes, this document also provides proforma conformance test reports
templates for both the Front End and Back End test purposes.
ISO 17575-2 contains more information regarding the requirements against which the conformance is
evaluated in this document.

Elektronsko pobiranje pristojbin - Ugotavljanje skladnosti opreme s tehnično specifikacijo ISO/TS 17575-2 - 1. del: Zgradba preskuševalnega niza in namen preskušanja (ISO/TR 16401-1:2018)

Ta dokument zajema namen preskušanja za čelni komunikacijski programski vmesnik, ki zajema funkcije, povezane z obravnavanjem dogodkov, obravnavanjem sej, primitivi komunikacijskih storitev (tj. pošiljanje in prejemanje ADU) in vidnim stanjem prenosa. Zajema komunikacijske storitve elektronskega pobiranja pristojbin, opisanih v ISO 17575-2:2016, točka 5, in Izjave o skladnosti izvedbe protokola (PICS), pro forma v ISO 17575-2:2016, B.2. Zahteve, povezane s kapaciteto spomina čelnega dela sistema, ne spadajo na področje uporabe tega dokumenta.
Ta dokument zajema namen preskušanja za čelno aplikacijo v zvezi z vzpostavitvijo seje na podlagi zahteve zalednega dela sistema in v zvezi s ponovno vzpostavitvijo seje, kadar je bila prekinjena seja, ki jo je zahteval zaledni del sistema.
Drugih zahtev v zvezi s čelno aplikacijo iz ISO 17575-2 ni. Osnovne zahteve glede komunikacijske tehnologije za plasti 1 do 4, določene v točki 6 tehnične specifikacije ISO 17575-2:2016 ne spadajo na področje uporabe tega dokumenta.
Prav tako na področje uporabe tega dokumenta ne spada zaledni komunikacijski programski vmesnik. V skladu s tehnično specifikacijo ISO 17575-2 se pričakuje, da bodo ti čelni komunikacijski programski vmesniki izraženi v zalednem (BE) komunikacijskem programskem vmesniku, čeprav zaledni komunikacijski programski vmesnik ne spada na področje uporabe tehnične specifikacije ISO 17575-2.
Nameni preskušanja so organizirani po skupinah preskuševalnih nizov, ki so zasnovani za čelni komunikacijski programski vmesnik in za čelno aplikacijo.
Ta dokument poleg namenov preskušanja določa tudi predloge za poročila o pro forma preskušanju skladnosti za namene preskušanja čelnega in zalednega dela.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction

This document is part of a set of standards that supports interoperability of autonomous electronic fee

collection (EFC) systems. Autonomous systems use satellite positioning, often combined with additional

sensor technologies such as gyroscopes, odometers and accelerometers, to localize the vehicle and to

find its position on a map containing the charged geographic objects, such as charged roads or charged

areas. From the charged objects, the vehicle characteristics, the time of day and other data that are

relevant for describing road use, the tariff and ultimately, the road usage fee is determined.

The ISO/TR 16401 series provides tests to assess the Front End Communications API and Front End

Application behaviours compliancy towards the requirements listed in ISO 17575-2. This document

contains the definition of such tests in the form of test purposes, listing the initial conditions, references

and individual steps in a structured textual manner. ISO/TR 16401-2 contains the identical tests

written in Testing and Test Control Notation version 3 (TTCN v3).

Autonomous on-board equipment (OBE) operates without relying on dedicated roadside infrastructure

by employing wide-area technologies such as Global Navigation Satellite Systems (GNSS) and Cellular

Communications Networks (CN). Therefore, autonomous systems can also be referred to as GNSS/CN

systems.
ISO/TR 16401-1 is based on
— ISO 17575-2, and
— the ISO 9646 family of standards on conformance test methodology.

Test suite structure and test purposes
1 Scope

This document covers the test purposes for Front End Communications API covering functionalities

related to instance handling, session handling, communication service primitives (i.e.

sending/receiving of ADUs) and visible state transitions. It covers EFC communication services

described in ISO 17575-2:2016, Clause 5 and PICS proforma in ISO 17575-2:2016, B.2. Claims related to

Front End storage capacity are out of scope of this document.

This document covers the test purposes for Front End Application related to session establishment on

Back End request and related to session re-establishment when session requested by Back End failed.

There are no other claims with respect to Front End Application described in ISO 17575-2.

The underlying communication technology requirements for layer 1 to 4 specified in ISO 17575-2:2016,

Clause 6 are out of scope of this document.

Similarly, Back End Communications API is out of scope of this document. According to ISO 17575-2

it is expected that these Front End Communications API will be “reflected” in the BE; however, BE

Communications API is out of scope of ISO 17575-2.

Test purposes have been organized into the test suite groups, designated for the Front End

Communications API and Front End Application, respectively.

Aside from the test purposes, this document also provides proforma conformance test reports

templates for both the Front End and Back End test purposes.

ISO 17575-2 contains more information regarding the requirements against which the conformance is

evaluated in this document.

Annex A
(informative)
Test purposes (TP) for Front End Communications API
A.1 Overview

This annex contains the test purposes (TP) for the conformity evaluation of Front End Communications

to ISO 17575-2.
A.2 TP symbols conventions
A special notation and symbol convention is used, as defined in this subclause.

Definitions of the symbols used in the description of the TPs are provided in Table A.1.

Table A.1 — Description of TP Symbols
Symbol Description
XXX(Type1 = value1) ⇒ The tester executes an XXX method of FE Communications API
with argument Type1 having a value of value1.
Value1 is stored in the tester's memory for further TP processing.
⇐ R:ReturnedType The IUT returns a value of type ReturnedType.
⇐ C:CallbackName (Type1) The IUT provides a callback CallbackName receiving
variable of type Type1.
Type ISO 17575-2 Anytime Type defined in ISO 17575-2 is used.
It means a variable of Type.
A → B A “is transformed” into B.
Ø Means “empty” or “not set”.
A | B A or B
A ! = B A is not equal to B.
i = i + 1 Increment variable i by 1.

In testing the Front End Communications API, it is needed to trigger operations and observe the IUT

feedback both from the Front End Application and remote end (i.e. Back End) perspective. Thus, there

are two test points located as shown in Figure A.1.

Application emulation test point is used directly with the IUT and emulates the Front End Application

layer. It is identified in the following test purposes by the AppEm discriminator.

Remote End emulation test point is linked with the IUT over communications channel. Depending on

the test purposes, it emulates application, presentation and session layer. It is identified in the following

test purposes by the RemEnd discriminator.

A.3 Instance handling

These test purposes apply to instance handling as described in ISO 17575-2:2016, B.2, with respect to

following PICS proforma entries:
— API supports InitialiseInstance;
— API supports SetParameter;
— API supports GetParameter;
— API supports DeleteParameter;
— API supports DropInstance;
— API supports StackAvail.
A.3.1 BV test purposes (Behaviour Valid tests)
Test subgroup objective:

— to test IUT behaviour with respect to instance initialization, including multiple instance handling in

parallel;
— to test IUT behaviour with respect to parameter setting and updating;
— to test IUT behaviour with respect to parameter getting;
— to test IUT behaviour with respect to parameter deleting;
— to test IUT behaviour with respect to availability of communications stack;

— to test IUT behaviour with respect to dropping the session with the following severities:

— SENormal;
— SEUrgent;
— SEUnconditional.
