Research And Realization On Multi-mode Terminal Test Platform

As wireless communication technology continues to evolve, the terminal as animportant part of the industry chains attracts more and more industry attentions. Since2G,3G and LTE multi-mode networks will be coexisted for a period，the multi-modeterminal has become the development trend of the industry.Since the software (SW) update cycle is short and regression test workload is highduring development phase, multi-mode terminal brings regression test process newchallenges, not only increases the intensity of the test, but also increases the complexityof the testIn this thesis, the automation test platform for the multi-mode terminal, whichsupports TDD technology described in3GPP system, are studied and developed. Thisthesis focuses on designing test cases， setting up test platform and developingautomation test tool. This thesis is organized as following:At beginning, the evolution of wireless communication technology, TDD and FDDmethods are briefly introduced. Then the current test platform status and its limitation,the background and the meanings of this thesis are discussed.In Chapter two, the multi-mode terminal categories defined in3GPP specificationsand their architectures are discussed. Then according to regression test characteristics,the test cases, test platform and software requirements are analyzed.In Chapter three, test parameters and test methods are designed for RF test casesand iRAT cell re-selection test cases.In Chapter four, the test platform setup and the development of the automationtools are introduced. GPIB bus is used to connect host PC and test instruments. Thegraphical programming language VB6.0is used to develop the automation test tool,calling VISA library functions to control the test instruments and achieve testautomation.In the end, the whole thesis is concluded.
