| Along with the determination of TDD spectrum resources, TD-LTE industrialization process is accelerated. In order to ensure the healthy development of the industry chain and the security of future business data, the terminal security mechanism in compliance with international standard is very important. This thesis is rooted in TD-LTE terminal protocol conformance testing system security mechanism part.Through the process of theoretical research, function analysis, code realization, debugging and verification, this thesis completes topic goal whose name is "Realization of security mechanism in TD-LTE terminal protocol conformance testing system based on TTCN-3". The realization of the subject is benefit to TD-LTE chip manufacturers, which can be used to security mechanism of conformance testing, analysis, perfect, to ensure the quality of the chip, and be helpful for the vigorous development of the TD-LTE industrial chainThis thesis firstly summarizes the TD-LTE system technology background and the significance of security mechanism, and introduces function of terminal protocol conformance testing system, system software and hardware structure, and terminal protocol conformance testing language TTCN-3Secondly, TD-LTE security mechanism procedures and algorithm are analysed from protocol perspective. Then summarize the requirement of security mechanism in protocol conformance testing system, so design and realization will go on wheels.Again, based on theoretical research, design and implementation, completeness and correctness of realization will be verficated based on procedures, and terminals also can pass these procedures.In the end, the thesis summarizes the full text, and prospects of terminal protocol conformance testing system and TD-LTE development of security mechanism. The realization results of this research have been applied to the TD-LTE terminal protocol conformance testing system, and several terminas have verificated through. |
