5 Detection environment for message layer of LTE-based V2X technology
5.1 TS architecture
The TS architecture of LTE-based V2X is shown in Figure 1. TS is mainly composed of a PC host and a system simulator, both communicating through Ethernet.
The PC host, the upper computer in the TS, realizes the operation of equipment running, system self-checking and TTCN-3 executable test case, and may automatically test and control a tested terminal through relevant command interfaces.
The system simulator realizes underlying protocol stack function of the LTE-based V2X technology, and communicates with the terminal through air interface.
If the TS needs the DUT to feed back the relevant test state or test results in the test process, the latter feeds back the relevant information through Ethernet.
