19、 Intelligent Transport Systems (ITS). The present document is part 3 of a multi-part deliverable covering Conformance test specifications for Cooperative Awareness Basic Service (CA) as identified below: Part 1: “Test requirements and Protocol Implementation Conformance Statement (PICS) pro forma“;
20、Part 2: “Test Suite Structure and Test Purposes (TSS Part 3: “Abstract Test Suite (ATS) and Protocol Implementation eXtra Information for Testing (PIXIT)“. The development of ITS test specifications follows the guidance provided in the ETSI EG 202 798 i.1. Therefore this ATS documentation is also ba
21、sed on the guidance provided in ETSI EG 202 798 i.1. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for t

The test system will simulate valid and invalid protocol behaviour, and will analyse the reaction of the IUT. Figure 1: Abstract proto
43、col tester - CA 4.2 Test Configuration This test suite uses a unique test configuration in order to cover the different test scenarios. In this configuration, the tester simulates one ITS station implementing the CAM protocol. 4.3 Test architecture The present document implements the general TTCN-3
44、test architecture described in ETSI EG 202 798 i.1, clauses 6.3.2 and 8.3.1. ETSI ETSI TS 102 868-3 V1.4.1 (2017-03)9 Figure 2 shows the test architecture used for the CA ATS. The CA test component requires using only the Main Test Component (MTC). The MTC communicates with the CA SUT over the camPo
45、rt. The camPort is used to exchange CA protocol messages between the CA test component and the CA IUT. The Upper tester entity in the SUT enables triggering CA functionalities by simulating primitives from application or LDM entities. It is required to trigger the CA layer in the SUT to send CA mess
46、ages, which are resulting from upper layer primitives. Furthermore, receiving CA messages may result for the CA layer in sending primitives to the upper layer (sending Data to LDM for instance). Figure 2: Test system architecture 4.4 Ports and ASPs (Abstract Services Primitives) 4.4.1 Introduction T
47、wo ports are used by the CA ATS: The camPort, of type CamPort. The utPort, of type UpperTesterPort. ETSI ETSI TS 102 868-3 V1.4.1 (2017-03)10 4.4.2 Primitives of the camPort Two types of primitives are used in the camPort: The CamInd primitive used to receive messages of type CamPdu. The CamReq prim
48、itive used to send messages of type CamPdu. These two primitives use the CamPdu type, which is declared in the CAM.asn ASN.1 module, following the ASN.1 definition from ETSI EN 302 637-2 1. CamPdu := SEQUENCE header ItsPduHeader, cam CoopAwareness 4.4.3 Primitives of the utPort This port uses two ty
49、pes of primitives: The UtInitialize primitive used to initialize IUT. The UtTrigger primitive used trigger upper layer events in IUT. 4.5 Executing CA tests in secured mode All the CA tests, with the execption of the SSP tests, can be executed with security enabled or with security disabled. The choice of running the CA tests in secured or non-secured mode has no impact on the result of the CA tests because the test verdicts assess CA protocol behaviour only. The SSP tests can only be executed in
