摘要:
基于TTCN语言的一致性测试原理和测试方法,针对TD-LTE终端协议一致性测试系统中无法实现个性化流程测试的问题,提出用户自主开发测试例的方案。介绍了TD-LTE终端一致性测试系统的软件结构,在此基础上重点研究了基于IBM Rational Systems Tester、其他TTCN工具、非TTCN语言和GUI的四种开发方案。通过仿真平台测试表明,个性化流程方案设计合理。%Based on the TTCN language confor-mance test principle and test method, user self-de-velopment test cases program was proposed to solve the personalized flow testing which can't be achieved in TD-LTE terminal protocol conformance test sys-tem. Firstly, software architecture of TD-LTE termi-nal protocol conformance test system was introduced, then four development programs were designed based on IBM Rational Systems Tester, other TTCN tools, non TTCN language and GUI respectively. Simula-tion platform test show that the personalized flow testing programs are reasonable.

摘要:
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 TTCN (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.% 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。

摘要:
设计并实现了LTE(long term evolution,长期演进)终端侧的随机接入过程,首先研究了随机接入过程的应用场景和类型,然后以RRC(radio resource control,无线资源控制协议)连接建立场景为例设计了随机接入过程的流程,最后通过SDL/TICN仿真平台对随机接入过程进行了测试和验证,从测试运行结果中可知,随机接入过程的实现符合3GPP组织一致性测试要求.

摘要:
The session initiation protocol (SIP) is a signaling protocol for Internet telephony, multimedia conferencing, presence, event notification, and instant messaging. With the gaining popularity, more and more SIP implementations have been developed and deployed. How to guarantee the conformance of those SIP implementations is the key point of interconnection and interoperation among them. This paper proposes the test method and architecture for the SIP protocol based on the IPv6 tester system. Tree and tabular combined notation (TTCN-2) is adopted to describe the test suite. With an enhanced reference implementation, the data-processing ability to the original test system has been greatly improved. In the following test practices, some errors have been found in the SIP entities under test. It is proved that the proposed test method and architecture are effective to verify the conformance of the SIP entities, and the result of the conformance test may provide helpful reference to the development of SIP products.
