为了进行TD-LTE(时分长期演进)系统级测试仪表的开发, 需要对各层的功能进行测试和验证, RLC(无线链路控制)层主要完成数据处理功能。文章在对3GPP(第3代合作伙伴计划)开发测试协议进行认真分析研究的基础上, 首先在CCS软件中编写测试例进行软仿真来验证RLC层协议一致性; 然后搭建TTCN-3(测试与测试控制第三版)软件平台, 通过系统级的测试来验证RLC层的功能。结果表明, 在两种平台下该层功能都得以正确实现, 这为测试仪表的开发奠定了基础。

In order to develop the testing instruments for TD-LTE systems, it is necessary to test and verify the functions of every layer and the main objective of the Radio Link Control (RLC) layer is to perform the data processing function. On the basis of careful research and analysis of the 3GPP development and testing protocol, this paper first compiles and writes the test cases in software CCS for simulation so as to verify the conformance of the RLC protocol. Then, it builds the TTCN-3 platform and verifies the functions of the RLC lay by system-level tests. The verification results prove that all the functions of this layer are correctly implemented on these two platforms, which lays a sound foundation for the development of these test instruments.
