摘　　要：TD-LTE终端协议一致性测试仪是移动终端入网测试的标准检测仪器。为保证其模块间的通信,本文提出一种基于TTCN测试用例集编解码的解决方案。该方案通过适配TTCN码流以及C语言码流完成上下层模块间的通信,实现了测试仪与UE间的正常信令交互。该方案的实现对TD-LTE产业化具有积极的推动作用。TD-LTE terminal protocol conformance testing instrument is used for access detection of mobile terminals. This paper proposes a program of encoding and decoding which is based on TYCN （Tree and Tabular Combined Notation） testing suit so as to resolve the communication between modules in the tester. The program completes the communi- cation between the upper and lower modules through the adaption of TTCN streams and the C languages streams, and then resolves the normal sig- naling interactions between tester and the UE. The program has entered the stage of practical applica- tion and will be a positive role in promoting the in- dustrialization of TD- LTE.
