The test system is mainly composed of PC host and system simulator, which communicate with each other through Ethernet. PC host is the upper computer in the test system, which realizes equipment operation, system self-inspection and TTCN-3 executable test case operation, and can realize automatic test and control of the terminal under test through relevant command interfaces. The system simulator realizes the underlying protocol stack function of LTE-based vehicular communication technology, and the system simulator communicates with the terminal through air interface. If the test system needs DUT to feed back the relevant test status or result information during the test process, DUT feeds back the relevant information through Ethernet. Note: DUT test can be either OBU or RSU. Figure 1 Test system architecture 4.2 Test conventions The test cases and scenarios involved in this standard shall follow the following conventions:  Each test case tests only one wireless device under test at a time, and can’t test multiple wireless devices at the same time;  Unless otherwise specified, the “DSM message” mentioned in this standard refers to DSM message whose packet type is “Non-IP” and does not contain “DSMP Extension Domain Indicator” (i.e., the value is taken as 0);  Unless otherwise specified, the DSM message length (DsmMaxLength) value in MIB is 1400 bytes;  The related contents of DSA test of LTE-based vehicular communication technology are not within the definition scope of this standard;  Except for special instructions, the specific test operations for test cases involved in this standard are conducted according to those shown in Figure 2.
