Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS). The present document is part 1, sub-part 3 of a multi-part deliverable covering the test s
16、pecifications for High Data Rate (HDR) Dedicated Short Range Communication (DSRC).Full details of the entire series can be found in part 1-1 2. ETSI ETSI TS 102 708-1-3 V1.1.1 (2010-03) 51 Scope The present document contains the Abstract Test Suite (ATS) and partial PIXIT proforma to test the “Dedic
17、ated Short Range Communication“ (DSRC) “High Data Rate“ (HDR) data link layer 1. The objective of this abstract test specification is to provide test scripts for testing conformance of DSRC-HDR equipment specified in 1 giving a high probability of inter-operability between different manufacturers eq
18、uipment. All formal test scripts provided in the present test specification are based on TS 102 708-1-2 3. The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 4, ISO/IEC 9646-2 5 and ISO/IEC 9646-5 6), ETS 300 406 7 and ES 201 873-1 8 specifying the TTCN-3 core language are u
19、sed as a basis for the test methodology. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

The System under test comprises also the PHY layer and t
34、he application layer, whixh are necessary to perform the IUT tests. The tester executes the TTCN-3 scripts of the present Test Specification, running on an emulated PHY layer.

38、terface (TCI) and the TTCN-3 Runtime Interface (TRI), which specify the interface between Test Management (TM) and TTCN-3 Executable (TE) entities, and TE, SUT Adapter (SA) and Platform Adapter (PA) entities, respectively. Out of these two interfaces the TRI has been standardized in ES 201 873-5 9,
39、whereas the specification and implementation of the TCI is in ES 201 873-6 10. The part of TS that deals with interpretation and execution of TTCN-3 modules, i.e. the Executable Test Suite (ETS), is shown as part of the TTCN-3 Executable (TE). This ETS corresponds either to the executable code produ
40、ced by a TTCN-3 compiler or a TTCN-3 interpreter from the TTCN-3 ATS in a TS implementation. The remaining part of the TS, which deals with any aspects that cannot be concluded from information being present in the TTCN-3 ATS alone, can be decomposed into Test Management (TM), SUT Adapter (SA) and P
41、latform Adapter (PA) entities. In general, these entities cover a TS user interface, test execution control, test event logging, communication of test data with the SUT and timer implementation.

43、LLC Test System Architecture, as described in figure 3, shows the interaction between the test case execution (TE) and the test adapter, as required to cover the test purpose requirements. LLC frames, sent to the SUT and received from the SUT are handled by the SA in order to fit the TTCN-3 types (s
44、ee port mapping in the clause 4.2.3). In particular, it is not smart to manage the values of some fields of the frames, which require dynamic bitwise computation, like for instance the frame flags and the Frame Check Sequence fields. As consequence, the llc port does only manage frames without flags
45、 and FCS. Flags and FCS shall be autonomously and correctly managed by the “PHY layer emulation“. As some test purposes require to generate specific or invalid values of flag and FCS, the crtl port is used to control these actions from the TTCN-3 test cases. Furthermore, certain timing values can no
46、t be measured using the TTCN-3 test commands, like for instance closing flag to closing flag timing. Thus this value shall be measured by the SUT adapter and transmitted to the TTCN-3 over the ctrl port. see port mapping in the clause 4.2.3. RSU test cases requires to trigger some actions in the IUT
47、, which result in sending the expected frames to the tester. Triggering these action is realized in TTCN-3 by using the action operation (see in ES 201 873-1 8). According to the TTCN-3 standards, the action operation can result in different types of behaviour. For the best automatization of the tes
48、t system, it is recommend to use the action operation to trigger the IUT for sending the required frames. At a minimum, the TTCN-3 test system shall generate text windows to invite the test operator to activate the necessary procedures in the IUT for sending the required frames. 4.2.3 Port mapping 4
