27、stract test method 4.1 Abstract protocol tester In general, the conformance test system architecture as illustrated in the ITS testing framework ETSI EG 202 798 i.1 applies. This ITS testing framework is extended by a cnPort and the related configuration / event notification transport as illustrated

28、 in figure 1. ETSI ETSI TS 102 760-3 V1.1.1 (2014-06)7SUTITS test systemConfiguration / notification transportTest controlTTCN-3 test componentsITS lower layersCodecUpper tester applicationITS lower layersUpper tester transportIUTltPortutPortLower layers linkUpper tester transport linkConfiguration

29、/ notification transportUpper tester transportcnPortConfiguration / notification linkTest adapterFigure 1: Abstract protocol tester - General approach For the present document, the IUT is the ATSP. The upper tester application allows accessing the IN-SAP of the IUT. Lower layer protocols indicated b

30、y the block “ITS lower layers“ are not existent, as the ATSP constitutes the lowest layer (ITS-S access layer) of the ITS-S station and communication architecture ISO 21217 i.2. The configuration and event notification access allows to access the IUT via the MI-SAP. NOTE 1: The ITS-S access layer co

31、rresponds to the OSI layers 1 and 2. ISO 21218 1 specifies how to use any kind of access technology in an ITS station (ITS-S). Thus ISO 21218 does not contain details of this variety of possible access technologies. Testing of ISO 21218 thus needs to apply the ATSPs to a specific access technology.

32、An “Implementation Under Test“ IUT contained in a “System Under Test“ (SUT) is connected to the ITS test system via a lower layers link and an upper tester transport link and a configuration / notification link. These links allow accessing the points of control and observation (PCO) of the IUT. Thes

33、e three links between ITS test system and SUT may be realized differently, such that there might be one or two or three physical links. NOTE 2: The lower layers link is the link of a specific access technology, e.g. 802.11(p) radio link as specified in ISO 21215 i.5. Accessing the IUT is performed w

34、ith the “ITS station-internal management communications protocol“ (IICP) specified in ISO 24102-4 i.4 as illustrated in figure 2. Further on an auxiliary ITS station unit (AITS-SU) with a communication interface (CI) of same access technology as used in the IUT is needed for the lower layers link. F

35、or this purpose, the ITS test system, the AITS-SU and the SUT together behave as parts of an ITS station unit, where each of these three units constitutes an ITS station communication unit (ITS-SCU) as specified in ISO 21217 i.2 and ISO 24102-4 i.4. The unique address of the ITS test system ITS-SCU

36、is ITS-SCU-ID = 3 as specified in ISO 24102-4 i.4. The unique address of the CI ITS-SCU is ITS-SCU-ID = 4 as specified in ISO 24102-4 i.4. The unique address ITS-SCU-ID of the SUT is in the range of 8 through 66 534 and may be selected by different means, e.g. using the initialization procedure of I

38、he reaction of the IUT upon a given stimulation. 4.2 Test architecture The present document implements the general TTCN-3 test architecture described in ETSI EG 202 798 i.1, clause 6.3.2 and clause 8.3.1. Figure 3 shows the TTCN-3 test architecture used for the ATSP ATS. The MTC is of type ItsATSP a

39、nd communicates with the SUT over atspPort (PCO Link) in order to exchange access technology specific PDUs between the ATSP test component and the ATSP IUT. The “ITS lower layers transport“ system adapter connects to the AITS-SU containing the same access technology as used in the SUT. This connecti

40、on uses PDUs which are equivalent to the IN-SAP service primitives specified in ISO 21218 1. The MTC communicates with the SUT over the utPort (PCO IN-SAP) in order to trigger ATSP functionalities by simulating service primitives from the IN-SAP services. It is required to trigger the ATSP in the SU

41、T to send frames. Furthermore, receiving frames may result for the ATSP in sending primitives to the upper layer, which is the ITS-S networking 5.2 Naming conventions 5.2.1 General guidelines The present document follows the naming convention guidelines provided in ETSI EG 202 798 i.1.
