3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in [1], [2] and [i.1] apply.
3.2 Abbreviations
For the purposes of the present document, the abbreviations given in [1], [2], [i.1] and the following apply:
FNTP Fast Networking & Transport Protocol
IUT Implementation Under Test
SUT System Under Test
4 Test suite structure
In general, the conformance test system architecture as illustrated in the ITS testing framework [i.1] applies. Such SUTs
which support ITS station-internal management communications [i.4] may benefit from the conformance test system
architecture illustrated in figure 1, where the access to the IUT from top, i.e. in general via the "Upper tester
application", is performed via the MN-SAP.

Figure 1: Conformance test system architecture for SUTs compliant with [i.4]
In general, the upper tester application [i.1] allows to access the NF-SAP of the IUT. Acess to the full functionality of
the NF-SAP is also possible via the MN-SAP, applying the MN-Command "SimNFcmd". Similarly, access of the
networking and transport layer protocol to the ITS facilities layer (Upper tester application) is possible via MN-SAP,
applying the MN-Request "SimNFreq".
NOTE: This approach to implement the functionality of "Upper tester transport" and "Upper tester application" in
the SUT by means of ITS station-internal management communications was initially introduced in the
test specification for ISO 21218 [i.8] and will be implemented in a fully developed way in the next
version of ISO 24102 [i.3], [i.4] such that it is applicable for IUTs located in either the ITS access layer,
or the ITS networking & transport layer.

5 TP basics
5.1 TP definition conventions
The TP definition is built according to the guidelines provided in the ITS testing framework [i.1], applying a formalized
language with pre-defined keywords for the behaviour description.
5.2 TP identifier naming conventions
The identifier of the TP is built according to tables 1 and 2 as recommended in the ITS testing framework [i.1].
Table 1: TP naming convention for FNTP [1]
TP/////
= root FNTP Fast Networking & Transport
Layer Protocol
= group TXP Transmit Packets
RXP Receive Packets
CIP CIP Management
SEC Secure Communications
= sub-group BP Basic Procedure
EP Extended Procedure
FP Forwarding Procedure
= type of testing BV Valid Behaviour Tests
BI Invalid Syntax or Behaviour Tests
= sequential number 01 to 99
NOTE 1: CIP management is only tested in the TPs of group "CIP".
NOTE 2: The groups TXP and RXP are restricted to "transmit to / receive from an ITS peer station",
i.e. the group TXP also includes TPs to test reception of an FNTP station-internal forwarding
NPDU from another local ITS-SCU, and the group RXP also includes TPs to test
transmission of an FNTP station-internal forwarding NPDU to another local ITS-SCU.
NOTE 3: A sub-group may not apply for all groups.

TPs for FNTP are specified in clause 6.
Table 2: TP naming convention for ISO 15628 support [i.5]
TP/////

O2 Option 2

TPs for ISO 15628 [i.6] support will be specified in a future version of the present document.
TPs for LPP support specified in [i.2], [i.5] may be specified in a future version of the present document.
5.3 Rules for behaviour description
The description of the TP is built according to the guidelines provided in the ITS testing framework [i.1].
ETSI
8 ETSI TS 102 985-2 V1.1.1 (2012-07)
5.4 Sources of TP definitions
All TPs are specified according to [1].
5.5 TP proforma
[i.1] proposes a TP proforma which is used in the present document. The fields of this proforma as used in the present
document are explained in table 3.
Table 3: TP proforma field description
TP Header
TP ID The TP ID is a unique identifier according to the TP naming conventions in tables 1 and
2.
Test objective Short description of test purpose objective according to the requirements from the base
standard.
Reference The reference indicates the clauses of the reference standard specifications in which the
conformance requirement is expressed.
PICS selection
Reference to the PICS statement involved for selection of the TP. Contains a Boolean
expression. May contain PICS acronyms specified in table.
This section is only used in case an optional or conditional behaviour needs to be
selected. Mandatory behaviour is not identified here.
TP Behaviour
Initial conditions The initial conditions define in which initial state the IUT has to be to apply the actual TP.
(optional)
In the corresponding "Test Case" (TC), when the execution of the initial condition does
not succeed, it leads to the assignment of an Inconclusive verdict.
Expected behaviour Definition of the events, which are parts of the TP objective, and the IUT are expected to
(TP body) perform in order to conform to the base specification. In the corresponding TC," Pass" or
"Fail" verdicts can be assigned there.

5.6 PICS mnemonics
The PICS mnemonics presented in table 4 are used in the TP proforma.
Table 4: PICS mnemonic for ISO 29281-1 [1]
