Construction And Application Of Automated Test Platform For Performance Of Mobile Communication Network Nodes

From 2G,3G to the now fully mature 4G technology and the upcoming commercial 5G,the mobile communication network technology update cycle is getting shorter and shorter,users have more and more demand for the network,so the communication company needs to develop new features more and more.Due to the particularity of the communication product,before the product is officially delivered to the customer,the real-world scenario must be simulated for performance testing and system testing to avoid problems that affect the user's experience after the formal deployment.At the same time,telecom customers have shorter and shorter product delivery cycle requirements.Therefore,traditional manual testing can not fully meet the needs of today.Highefficiency automated testing is urgently needed by the entire communications industry.This paper is based on this background to build a performance automation test platform for mobile communication networks.The whole platform adopts the completely independent design of the tested system and the automated testing tool.The tested system hardware is deployed in a fixed laboratory.The tester remotely manipulates through the Linux test terminal,and uses the GSS file server to communicate the communication service software and related.Configure the incoming hardware carrier and simulate a peripheral network element,signaling and real users through the simulation tool Dallas to form a complete mobile communication network.The automated test tool is a Maven project that can be used to automatically test performance when imported through Eclipse.The content body is as follows:First,the background of the current communications industry and the automated test industry is introduced,and this leads to the need for efficient automated test tools.Then,the research and analysis of the research status at home and abroad have been carried out.Then,the specific requirements of the automated test platform for mobile communication performance are analyzed.After introducing the basic principles of the test object and the network topology of mobile communication and the basic knowledge of related nodes,interfaces and protocols,the evaluation parameters of the performance test of the mobile communication node are given,and finally based on the parameters and other basic conditions and future extensions.And maintenance gives the specific needs of the mobile communication automation test platform.Next,the tested system and automated test tools were designed separately.It includes the software and hardware design and function introduction of each component module of the tested system;the software design framework of the automated test tool and the main division of labor roles of each layer module.Among them,the hardware design architecture and software design of the hardware device MKX of the tested node SGSN-MME are given.The software tree design structure and module composition of Dallas simulation tool focus on the working principle of Dallas PM(performance management).The management and type of logs and important configuration files;the three-layer hierarchical design architecture of automated test tools(CATS,D-JCAT,JCAT)were separately studied and analyzed,and specific implementation schemes were given for functions and implementation.Finally,remotely control the SGSN-MME hardware through the Linux test terminal,install and start Dallas,build and deploy the tested system,and prove the stability and correctness of the platform by operating the Dallas user traffic model.Then introduce the automated test tool through Eclipse,take the upgrade test as an example to describe the steps and process of starting the automated test on Eclipse,and finally analyze the test results through the log,and prove the automated test of the node performance of the mobile communication.The platform can be applied smoothly in actual projects and achieve the expected results.
