Design of Conformance Testing System for C-V2X Standard Protocol

Protocol conformance test plays a necessary and important role in guaranteeing that Long Term Evolution-Vehicle to Everything (LTE-V2X) devices to meet the standards and achieve interoperability. Based on in-depth analyzing 3rd Generation Partnership Project (3GPP) release 14 and China LTE-V2X standards, in this paper, a LTE-V2X Conformance Testing Scheme is designed, while corresponding test process and message sets are defined. Test suite are designed according to message layer and network layer requirements. Finally, a test tool, VeTest, is proposed to realize conformance test. The work is significance for promoting the LTE-V2X standardization and interoperability.
