27、The communication covered by the test purposes of TS 102 916-2 2 address the exchange of frames over the physical radio connection between an OBU and an RSU. As the actual frame exchange is only available in the form of recorded trace files the test system has been modelled to cover the frames recei

28、ved from OBU or RSU via the virtual ports named obuPort and rsuPort in two Parallel Test Components (PTC). Synchronization between the two PTC is achieved via the comport; the additional connection commonOBURSUPort is used to allow display of the frame exchange in trace play mode. The verdictPort be

29、tween PTC rsuType and the Main Test Component (MTC) is used to transport verdict information to the MTC for statistical evaluation of the overall test results.

The frames are the downlink frames recorded in the trace file. ObuType: Test component type that “receives“ the frames destined to the real OBU via the unidirectio

The frames are the uplink frames recorded in the trace file. compPort: Bi-directional connection between RsuType and ObuType for the exchange of co-ordination messages. commonOBURSUPort: Bi-directional connection between RsuType and ObuType for the virtual exchange of

32、all “received“ frames for the purpose of creating the trace play representation of the real radio communication between RSU and OBU. verdictPort: Unidirectional port to from the RsuType to the MTC for the transport of verdict information. MTC: The MTC opens the trace file, counts the number of trans

33、actions stored and feeds the recorded downlink and uplink framesinto the rsuPort and the obuPort. The verdict information received via the verdictPort is used to calculate statistics for the totality of transactions stored in one trace file. 4.2 ATS structure 4.2.1 Test case grouping The ATS structu

34、re is based on the Test Purposes for mitigation techniques to avoid interference between European CEN Dedicated Short Range Communication (RTTT DSRC) equipment and Intelligent Transport Systems (ITS) operating in the 5 GHz frequency range as defined in TS 102 916-2 2.

36、This naming scheme provides a 1-1 correspondence of TP identifiers as defined in TS 102 916-2 2 and test case names. The TP identifier of TC_CAL_01 is TP_CAL_01. The test cases have been divided according to the functionalities into several groups: TC_CAL_xx Calibration Measurements TC_COEX_OBU_xx C

Each log file will typi

38、cally contain several hundred transactions. The test case granularity is defined to be one test case per transaction in the trace file. The TTCNg4863 test architecture design with the inclusion of the co-ordination port commonOBURSUPort allows for trace play so that the TTCNg4863 test operator will

39、have the impression to see a real message exchange between OBU and RSU. 4.3.1 Results per transaction Per transaction in the file the following result data is recorded: Chronological number of the transaction within the trace file (count starts with 0). Time length of the transaction in ms. Number o

40、f empty uplink frames from OBU to RSU. The TTCNg8823 test suite assigns a PASS verdict when the following conditions are fulfilled: Transaction is complete. Transaction duration 100 ms (PX_MAX_TRANSACTION_DURATION). No other OBU sends except the OBU under test. Number of empty uplink frames per tran

Name of the OBU under test. Total number of transactions in the trace file. Minimum transaction duration. Maximum

42、 transaction duration. ETSI ETSI TS 102 916-3 V1.1.1 (2012-05)9 Average transaction duration. Number of failed transaction. Transaction error rate based on the total amount of transactions in the trace file. The TTCNg8823 test suite assigns a PASS verdict when the following conditions are fulfilled:

43、 Transaction error rate is below defined threshold (PX_MAX_TRANSACTION_ERROR_RATE). Trace file is not empty.
