Embodiment Construction

[0048] For the TTCN protocol conformance test scheme in the prior art, the inspection of the PC5 interface data packet needs to make the test terminal enter the test mode E to perform the test, and the V2X service plane test can only check the PDCP data packet, resulting in the realization of the test. High requirements and technical problems of insufficient V2X business plane testing.

[0049] The present invention mainly proposes a test system, which can conveniently simulate various service scenarios of LTE-V2X in a laboratory, and test messages of the V2X service plane.

[0050] The method and device provided by the embodiment of the present application will be further described in detail below in conjunction with the accompanying drawings and specific application scenarios:

[0051] Such as figure 2 As shown, the embodiment of the present application provides a long-term evolution vehicle-to-everything LTE-V2X test system, and the test may specifically include a test co...

Abstract

The invention discloses a long-term evolution vehicle-to-everything LTE-V2X test system and a test method. The test system comprises a test control terminal used for constructing an LTE-V2X test case,sending various configuration parameters to an LTE system simulator, an LTE-V2X agent and a GNSS simulator, and constructing various V2X test scenes used for testing a V3 interface or a V1 interfaceto perform data transmission; constructing an HTTP data packet and/or a PDCP data packet needing to be transmitted through a V3 interface or a V1 interface, and performing message transceiving with aV2X terminal to be tested based on various V2X test scenes; and checking the HTTP data packet and/or PDCP data packet fed back by the V2X terminal to be tested, and determining the behavior of the V2Xterminal to be tested according to the checking result. According to the test system and method provided by the invention, the requirement on the test terminal is reduced, the protocol test on the test terminal is perfected, and the test efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, and in particular to a long-term evolution vehicle-to-everything LTE-V2X test system and test method. Background technique [0002] The existing Long Term Evolution LTE-V2X test solution specified by the 3rd Generation Partnership Project (3GPP) is a protocol conformance test solution based on TTCN (Testing and Test Control Notation, test and test control notation). It simulates the LTE network part (corresponding figure 1 The E-UTRA V2XPTC software module shown), SSUE (System Simulator User Equipment, user equipment on the system simulator side) part and LTE-V2X terminal for PC5 (The reference point between ProSe-enabled UEs used for control and user plane for ProSe Direct Discovery, ProSe Direct Communication and ProSe UE-to-Network Relay. Reference point for direct discovery, direct communication, and user equipment-to-network relay process between user equipment suppor...
