【摘要】：目前,第三代无线通信技术已经成为国内通信行业中的主导,而TD-SCDMA作为具有自主知识产权的标准在行业内占有举足轻重的地位,市场对TD-SCDMA制式终端的需求将会越来越大。虽然已经完成了TD-SCDMA R4至R7协议标准的制定,HSPA+协议标准也正在制定过程中,对终端芯片的协议测试依然是终端性能与网络可靠运行的重要保证。协议测试一方面可以验证终端侧协议实现的一致性,也可以测试终端对协议功能点的支持能力,是通信产业链中的重要环节之一。 TD-SCDMA终端协议测试平台支持终端协议一致性测试与用户自定义的协议测试。测试平台支持使用TTCN-2语言开发的协议测试例的运行、日志跟踪与结果分析等。测试平台具有完备性、一致性测试兼容性、用户开放性、协议可扩展性等功能特性。测试平台包含物理层软件、低层协议栈软件、高层协议栈软件及用户界面与主控软件四个部分。高层协议栈软件由TTCN-2协议测试部分与适配层软件部分组成。本文依据TD-SCDMA终端协议测试平台的功能特性,以及高层协议栈软件中TTCN-2协议测试部分的需求,分析了适配层软件的主要功能,完成了适配层软件的架构设计、线程设计与实现以及各主要功能模块的实现。最后,使用单元测试的方式验证了适配层软件编解码模块的功能实现与完备性,设计并实现了多个测试例验证了适配层软件的其他功能模块的实现与软件运行性能,验证了适配层软件对测试平台各功能特性的支持。
[Abstract]:At present, the third generation of wireless communication technology has become the dominant in the domestic communication industry, and TD-SCDMA, as a standard with independent intellectual property rights, plays an important role in the industry, and the market demand for TD-SCDMA standard terminals will be increasing. Although the standard of TD-SCDMA R4 to R7 has been completed, the protocol test of terminal chip is still an important guarantee of terminal performance and reliable operation of network. Protocol testing is one of the important links in the communication industry chain, which can verify the consistency of the terminal side protocol implementation and test the support ability of the terminal to the protocol function point on the one hand. TD-SCDMA terminal protocol testing platform supports terminal protocol conformance testing and user-defined protocol testing. The test platform supports the running of protocol test cases, log tracking and result analysis developed with TTCN-2 language. The test platform has the features of completeness, conformance test compatibility, user openness, protocol extensibility and so on. The test platform consists of four parts: physical layer software, low-level protocol stack software, high-level protocol stack software, user interface and master control software. High-level protocol stack software consists of TTCN-2 protocol test and adaptation layer software. According to the functional characteristics of TD-SCDMA terminal protocol test platform and the requirement of TTCN-2 protocol test part in the high-level protocol stack software, this paper analyzes the main functions of the adaptation layer software, and completes the architecture design of the adaptation layer software. Thread design and implementation as well as the implementation of the main functional modules. Finally, the functional realization and completeness of the adaptation layer software coding and decoding module are verified by unit test, and several test cases are designed and implemented to verify the implementation of other functional modules and the performance of the software. The support of adaptation layer software to the functional characteristics of the test platform is verified.
