Abstract


Dedicated Short Range Communication (DSRC, Dedicated Short Range Communication) is specialized in the field of intelligent transportation systems (ITS, Intelligent Transport System) technology for motor vehicles and roadside equipment to exchange information . DSRC system is divided into three parts: onboard unit ( OBU On Board Unit ) , the roadside unit (RSU Road Side Unit) , dedicated short-range communication protocol . March 19, 2007 , announced the People's Republic of China 's electronic toll collection dedicated short-range communication standard ( GB for short ) in this paper . Subsequently , many research institutions and manufacturers began GB OBU and RSU equipment R \u0026 D work . Them before application in order to ensure interoperability and compatibility between the OBU equipment and RSU equipment , protocol conformance testing , that is, whether the validation the DSRC protocol in these devices is consistent with the protocol standard specifies . 2004-2007 , the European Organization for Standardization (ETSI, European Telecommunications Standards Institute) has developed a standard the DSRC protocol conformance testing standards of Europe , and our only announced in January 2008 a draft protocol conformance testing method . GB DSRC protocol conformance test technology is of great significance . The paper in the background and demand-driven , through research and analysis of the ITU-T X.290 series of protocol conformance testing standard TTCN- 3 ( Testing and Test Control Notation - version3 ) standard and GB , while drawing on ETSI to develop the DSRC protocol conformance test standards , proposed the OBU device DSRC protocol abstract test suite , as well as the design of the protocol conformance test system based on TTCN-3 . This paper describes the process as follows: First, the basic theory of the brief protocol conformance test , classification , methods and processes ; TTCN-3 standard and based on TTCN-3 test software TTworkbench introduced ; once again , briefly the the DSRC technology background and standardization process , and introduced the GB DSRC protocol stack layers ; then the OBU device DSRC protocol abstract test suite design and proposed design , including the MAC sublayer abstract test set , LLC sublayer abstract test set and the three-part design of the the APP EQUIPAPP abstract Test Suite ; Finally, introduce the the OBU device DSRC protocol conformance test system design , including testing the main system and test the design of the front-end equipment , and test system validation .
