ETSI ETSI TS 102 869-3 V1.4.1 (2015-07)61 Scope The present document contains the Abstract Test Suite (ATS) for Decentralized Environmental Notification Basic Service (DEN) as defined in ETSI EN 302 637-3 1 in comp
23、liance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 5. The objective of the present document is to provide a basis for conformance tests for Decentralized Environmental Notification Basic Service (DEN) equipment giving a high probability of inte
24、roperability between different manufacturers equipment. The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 2 and ISO/IEC 9646-2 3) as well as the ETSI rules for conformance testing (ETSI ETS 300 406 6) are used as a basis for the test methodology. 2 References 2.1 Normative

The test system simulates valid and invalid protocol behaviour, and analyses the reaction of the IUT. Figure 1: Abstract protocol tester - DEN
42、 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 DEN protocol. 4.3 Test architecture The present document implements the general TTCN-3 test architectu
43、re described in ETSI EG 202 798 i.1, clauses 6.3.2 and 8.3.1. Figure 2 shows the test architecture used in for the DEN ATS. The DEN test component requires using only the Main Test Component (MTC). The MTC communicates with the DEN SUT over the denmPort. The denmPort is used to exchange DEN protocol
44、 messages between the DEN test component and the DEN IUT. The Upper tester entity in the SUT enables triggering DEN functionalities by simulating primitives from application or LDM entities. It is required to trigger the DEN layer in the SUT to send DEN messages, which are resulting from upper layer
45、 primitives. Furthermore, receiving DEN messages may result for the DEN layer in sending primitives to the upper layer (sending Data to LDM, for instance).

The utPort of type UpperTesterPort. 4.4.2 Primitives of the denmPort Two types of primitives are used in the denmPort: The DenmInd primitive, cont
47、aining the received messages of type DenmPdu, and a timestamp corresponding to the receipt time. The DenmReq primitive containing the sent messages of type DenmPdu. The DenmPdu type is declared in the DENM.asn ASN.1 module, following the ASN.1 definition from ETSI EN 302 637-3 1. DenmPdu := SEQUENCE
