| TD-LTE is a new generation of mobile communication technology with independent intellectual property rights of China, and its innovation is promoted by China Mobile. TD-LTE will be introduced commercially, and the terminal test will be an important part of the industrial chain which plays an important role in measuring the performance of the terminal. LTE terminal test attrachs attention by the government and industry gradually. In laboratory environment, the terminal conformance testing is the most simple and effective way to test the performance of mobile terminal, and also the only way of mobile terminal access tests.The purpose of protocol conformance testing is to ensure that the protocol implementation results of different entities in the network can communicate with each other, so as to ensure the correct and stable operation of the network. In describing the protocol conformance test cases, tests and testing control language (TTCN-3) has significant advantages. The article begins with today’s mobile communications background and introduces following contents in order:related knowledge of conformance testing, structure and syntax of all parts of the test language TTCN-3, functions of radio resource management and contents of RRM conformance testing, introduces of the RRM conformance testing system. In the end, the author, by analyzing the protocol, clarifies the sequence of test steps, determines implementation methods with conformance test system environment, and displays graduation results by concrete realization of the main part in the code.The implementation results of this study can operate correctly and stably. The test case has been debugged with several UE manufacturers, and it has been present in the instrument to test LTE mobile phone chips for business use. |
