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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 24101-2 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.
ISO 24101 consists of the following parts, under the general title Intelligent transport systems —
Communications access for land mobiles (CALM) — Application management:
⎯ Part 1: General requirements

ISO 24101-2:2010(E)
Introduction
This part of ISO 24101 is part of a family of International Standards for communications access for land mobiles
(CALM) which determine a common architecture, network protocols and air interface definitions for wireless
communications using cellular second generation, cellular third generation, 5 GHz, millimeter, and infrared
communications. Other air interfaces can be added at a later date. Air interfaces included in the CALM
International Standards provide facilities for broadcast, point-to-point, vehicle-to-vehicle, and vehicle-to-point
communications in the intelligent transport systems (ITS) sector.
The application management (AM), as defined in ISO 24101-1:2008, is the function to install, uninstall and
modify the ITS applications in a reliable and secure manner, and it addresses the following requirements:
a) installation of applications on CALM equipment after the equipment has been deployed;
b) updating of applications, including uninstalling, on on-board equipment (OBE) as well as wireless access
equipment (WAE) after the equipment has been deployed;
c) providing a standardized interface and functionality so that application developers and system operators
can successfully perform the functions in a) and b).
The purpose of this part of ISO 24101 is to specify a standardized conformance test for the AM, which verifies
that the function of the developed AM complies with the requirements specified in ISO 24101-1:2008. See
Figure 1.

5 General
The methodology and concepts of the AM conformance test are based on ISO/IEC 9646-1:1994.
An AM is developed firstly by the service provider in accordance with ISO 24101-1:2008. The developed AM
is software and is installed in the equipment under test (EUT), i.e. on-board equipment (OBE) or wireless
access equipment (WAE), prior to the AM conformance test.
Figure 2 shows the basic approach to the AM conformance test.

Figure 2 — Basic approach to conformance test
The basic approach is as follows:
a) collect requirements and specifications for the EUT;
b) prepare implementation conformance statement(s) (ICS) and implementation eXtra information for testing
[IXIT(s)];
c) prepare some test applications;
d) prepare test suites, i.e. the set of basic tests and advanced tests, and test system including the
verification means, etc.;
e) install the AM in the EUT, and install the test applications in the EUT and the test installer;
f) perform the conformance test;
1) download and install the test application into the EUT for installation or modification,
2) execute the test application,
3) confirm the results of the execution by the verification means, and compare the results with the
predetermined states, i.e. expected states;
i) when all results coincide with the predetermined states: verdict is set into pass,
ii) if there are one or more differences: verdict is set into fail;
4) send the command of uninstallation to the EUT and confirm the results of the execution by reading
the contents of the application management table (AMT) by the verification means, and
g) analyse results and prepare the conformance test report.
Figure 3 shows the conformance test process.

7 Functionality of entities
7.1 Test applications
Test applications are pre-installed in the test installer for installation or modification of applications, and also in
the EUT for uninstallation. See 9.1 and 9.5.
7.2 Test operator
The test operator installs, uninstalls or modifies the test applications via the test installer, and verifies the test
results by the verification means.
7.3 Test installer
7.3.1 OBE/WAE initiated download case
The test installer can be a test server in case of the OBE/WAE initiated download. See ISO 24101-1:2008.
External human machine interfaces (e.g. keyboard and display) may be temporally connected to the EUT via
its external interface (if necessary for the purpose of the AM conformance test) for providing the following
operator's human machine interfaces:
a) inputting commands to the EUT for installation, uninstallation or modification of an application;
b) display of the command execution results.
EXAMPLE “Under command execution”, “The command has successfully completed”, “Operator authentication
error” and “Manager certificate error” are examples of the display.
7.3.2 Installer initiated download case
In case of installer initiated download, the test installer has the functions specified in 7.3.1 inside.

---------------------- Page: 10 ----------------------
ISO 24101-2:2010(E)
7.4 Verification means
The verification means has the following functions:
a) confirming the execution results of the installed or modified application in cooperation with the
communication station (e.g. the communication results with the communication station is displayed on the
verification means);
b) reading and confirming the AMT information of the EUT;
c) rewriting the AMT information for intentional error;
d) setting the clock data of the EUT for the scheduled update (T-10 in Table 1);
e) setting the test conditions in the EUT (optional, e.g. halt under program execution).
NOTE The verification means can use a debugger, an emulator or a personal computer, etc. For example, a
debugger has useful functions such as the break point function and the contents rewriting function of a specified program
address. Also, in a simple case, the verification means can be a test installer (e.g. use of the AMT reading function).
7.5 Communication station
The communication station is used for verifying that applications in the EUT operate normally after installation
or modification of an application in cooperation with the verification means. The verification includes wireless
communication with CALM media.
7.6 Connection between entities
The connection methods between entities are not specified in this part of ISO 24101.
8 Test cases
8.1 General
Test cases are subdivided into basic tests and advanced tests.
The basic tests verify the basic operations of the AM, and the advanced tests verify that the AM can detect
abnormality when the test system is set intentionally in abnormal state.
8.2 Basic tests
Table 1 specifies the test cases of basic tests.

9 Test conditions
9.1 Test applications
Test applications shall have the following functions:
a) communicate with the CALM compliant communication station [CALM compliant];
b) meaning of normal operation is defined beforehand and the test applications are programmed according
to the definitions [Definitions in advance];
© ISO 2010 – All rights reserved 7

---------------------- Page: 12 ----------------------
ISO 24101-2:2010(E)
c) decision criteria of the test results are explicit [Unambiguity];
d) test applications are programmed so that the test results can be confirmed by communication with the
communication station and the verification means [Testability].
Test applications and verification means should co-operate with each other. Test applications should be
programmed to output or display the communication result with the communication station and the state of the
EUT to the verification means so that the test operator can confirm the test results by the verification means.
At least two applications with different manager certificates should be installed in the EUT for modification or
uninstallation, and at least two applications should be installed in the test installer for installation or
modification before the AM conformance test. See Table 3.
9.2 Common files
At least two common files should be installed in the EUT for modification or uninstallation, and at least two
common files should be installed in the test installer for installation or modification before the AM conformance
test. See Table 3.
9.3 Security information for operator authentication
Security information (e.g. public key) that allows the test installer to authenticate a test operator is stored in
the test installer in advance. Mutual authentication of the test operator and test installer shall precede any
exchange of application information. See ISO 24101-1:2008, 8.3.1.
The details of operator authentication are not specified in this part of ISO 24101.
9.4 Manager certificate for access control
Manager certificate is a manager's security credential containing information used to verify the identity of the
source of the credential. For example a manager certificate is sent by the manager of an application to the
OBE/WAE and is used by the AME to authenticate the manager. See ISO 24101-1:2008, 8.3.2.
At least six manager certificates may be set corresponding to the test applications and common files. See Table 3.
9.5 Combination example of test conditions
Table 3 shows the kind of test applications and common files that are required for the conformance test, and
also shows the combination example of pre-installation place, manager certificate and test purpose for each kind.
Table 3 — Combination example of test conditions
Test application or
Pre-installation place Manager certificate Test purpose

commonFile-b1 EUT managerCertificate-e Modification
commonFile-b2 Installer managerCertificate-e Modification
commonFile-c EUT managerCertificate-f Uninstallation
NOTE 1 The file names are shown as testApplication-a, -b, -c, etc. The number following it shows a version number.
NOTE 2 The file names are representatively shown as testApplication-a, etc. The naming method of file names (i.e. identification of
the application program) is specified in ISO 24101-1:2008, 8.1, although the file names of test applications can be named by the
arbitrary method distinguished mutually if the test applications are test purpose only and they are not installed in the OBE/WAE
products. This is applicable also to common files.

10 Test procedures
10.1 Basic tests
Annex A specifies the test procedures for each test case of the basic tests.
10.2 Advanced tests
Annex B specifies the test procedures for each test case of the advanced tests.
10.3 Notation for test procedures
Test procedures are specified in TTCN-3 in Annex A and Annex B. See ITU-T Recommendations Z.161
through to Z.167 and ETSI ES 201 873-1 about TTCN-3.
In TTCN-3, a message is transferred between TS and EUT via a port, i.e. a message is sent to EUT via a port
from TS, and TS receives the response message from EUT via the port. The response message is compared
with the expected message and verdict is set according to the comparison result. On the other hand, a
debugger may be used, for example as the verification means as shown in 7.4 in the implementation. In such
a case, from a viewpoint of TTCN-3, it is considered that the connector which connects the debugger to EUT
corresponds to the port and it is abstracted that a message is transferred via the port.
10.4 Commands in test procedures
Annex C specifies the commands that can be used for installation, uninstallation and modification in the test
procedures of Annex A and Annex B.

ISO 24101-2:2010(E)
11 Test results
Annex A also specifies the test results as the verdict in test procedures for each test case of the basic tests.
Annex B also specifies the test results as the verdict in test procedures for each test case of the advanced
tests.
12 Test documentation
12.1 Implementation conformance statement (ICS)
The implementation conformance statement (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. The ICS also states possible limitations in the implementation of the specification.
This part of ISO 24101 describes testing of implementations according to ISO 24101-1:2008.
Annex D contains the ICS proforma that shall be used for the ICS.
12.2 Implementation eXtra information for testing (IXIT)
The implementation eXtra information for testing (IXIT) is a statement made by the supplier or an implementor
of an implementation under test (IUT) which contains or references all of the information, in addition to that
given in the ICS, related to the IUT and its testing environment. IXIT enables a test laboratory or a test
organization to run an appropriate test suite against the IUT.
The IXIT shall also contain further information and procedures that are not specified in ISO 24101-1:2008 but
are pre-requisites to perform the test.
Annex E contains the IXIT proforma that shall be used for the declaration of the IXIT.
12.3 Test report
Each test carried out shall be documented. For each test a pass or fail verdict shall be given. The results of all
tests shall form the conformance test report.
