Introduction Communications for Intelligent Transport Systems (ITS) is standardized at ISO TC204 WG16 under the acronym CALM (Communications

7、 Access for Land Mobiles). The communications architecture of ITS and cooperative ITS and the concept of an ITS station (ITS-S) as a “Bounded Secured Managed Domain“ (BSMD) are specified in ISO 21217 i.1. The ITS-S architecture is based on the OSI model as illustrated in figure 1. An implementation

8、of a BSMD is named an “ITS station unit“ (ITS-SU), or more precisely a “Bounded Secured Managed Entity“ (BSME), which may consist of one or several physical units named “ITS station communication units“ (ITS-SCU). ITS-SCUs are interconnected via the ITS station-internal network specified in ISO 2121

ETSI ETSI TS 102 760-2 V1.2.1 (2014-06)83 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in ISO 21218 1, ISO 21217 i.1, ISO 24102-3 3, ISO 24102-4 i.3, ETSI

15、 TS 102 760-1 2 and ETSI EG 202 798 i.2 apply. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in ISO 21218 1, ISO 21217 i.1, ISO 24102-3 3, ISO 24102-4 i.3, ETSI TS 102 760 1 2 and ETSI EG 202 798 i.2 apply. 4 Test suite architecture ISO 21218 1 cannot be tested

16、without being applied to a specific communication interface (CI) specified in ISO 21217 i.1. Thus the test architecture presented in figure 3 shows also the OSI communication layers PHY and DLL which are below the “Communication Adaptation Layer“ (CAL), both in the system under test (SUT) and in the

18、 IN-SAP“, providing access to the IN-SAP of the IUT; “PCO MI-SAP“, providing access to the MI-SAP of the IUT; “PCO Link“, the communication link.

19、ons protocol“ (IICP) specified in ISO 24102-4 i.3 as specified in ETSI TS 102 760-3 i.4. Alternative approaches for the upper tester access specified in ETSI EG 202 798 i.2 also are possible. NOTE: Not using IICP to access IM-SAP and MI-SAP may cause extra cost to the applicant in order to adapt the

20、 SUT to the test environment in a test house. A SUT may contain several CIs. However in a given test at a given time, only a single of them together with the functionality of ISO 21218 1 shall constitute the IUT. Testing of a SUT containing several CIs thus requires repetition of the tests for all C

21、Is contained in the SUT. Tests for a configuration with several active CIs in a single SUT are not considered in the present document. 5 TP basics 5.1 TP definition conventions The TP definition is built according to the guidelines provided in the ITS testing framework ETSI EG 202 798 i.2, applying

22、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 table 1 as recommended in the ITS testing framework ETSI EG 202 798 i.2.

24、ines provided in the ITS testing framework ETSI EG 202 798 i.2. 5.4 Sources of TP definitions All TPs are specified according to ISO 21218 1. ETSI ETSI TS 102 760-2 V1.2.1 (2014-06)105.5 TP proforma ETSI EG 202 798 i.2 proposes a TP proforma which is used in the present document. The fields of this

25、proforma as used in the present document are explained in table 1. Table 1: TP proforma field description TP Header TP ID The TP ID is a unique identifier according to the TP naming conventions in table 1. Test objective Short description of test purpose objective according to the requirements from

26、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 speci

27、fied in table 2. 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 (optional) The initial conditions define in which initial state the IUT has to be to apply the actual TP. In the c

28、orresponding “Test Case“ (TC), when the execution of the initial condition does not succeed, it leads to the assignment of an Inconclusive verdict. Expected behaviour (TP body) Definition of the events, which are parts of the TP objective, the IUT is expected to perform in order to conform to the ba

29、se specification. In the corresponding Test Case,“Pass“ or “Fail“ verdicts can be assigned there. Final conditions (optional) Definition of the events that the IUT is expected to perform or shall not perform, according to the base standard and following the correct execution of the actions in the ex

30、pected behaviour above. In the corresponding Test Case, the execution of the final conditions is evaluated for the assignment of the final verdict. The following initial conditions shall apply for all TPs, if not defined differently in a specific TP: The Link-ID of all CIs not being in the CI state

31、“not_existent“ and of all existent VCIs shall be known to the ITS test system, see figure 3. The MIB of the CI / VCI shall contain default values except for the I-Parameters ISO 21218 1 listed below. - “MinimumUserPriority“ shall be set to zero if not requested differently. Additional initial condit

32、ions may apply for specific TPs. According to ISO 24102-3 3, the service primitives COMMAND.confirm and REQUEST.confirm shall be present in case of an error and may be omitted otherwise. The optional presence of confirm service primitives with ErrStatus indicating success are not explicitly included

33、 in the TPs, but will have to be considered in the abstract test suite, i.e. in part 3 i.4 of this multi-part deliverable.
