GSM-R网络互联互通E接口功能与互操作测试研究
|
摘要
我国铁路GSM-R网络的发展目标是在全国建立统一的移动通信网络，而不同厂家设备之间的互联互通就是实现目标的前提条件。对互联互通测试技术的研究是良好完成各厂家之间互通性测试任务的基础。本文以GSM-R网络E接口的互联互通测试为主线，分别从功能性和互操作性两个方面对GSM-R网络E接口测试技术做了深入研究。
功能性测试方面，本文阐述了功能性测试的概念，重点研究了功能性测试集的设计方法；在深入研究分析GSM-R网络E接口业务的基础上，分别考虑了测试集的完备性和冗余性，首先使用等价类划分方法设计了E接口的测试集，然后对其不足进行了分析，并提出了一种新的设计方法，最后对两种设计方法进行了对比分析，对如何设计GSM-R网络互联互通测试集提出了建议。
互操作性测试方面，本文介绍了互操作性测试方法及研究现状，分析了互操作性测试和功能性测试的关系。随后研究了互操作性测试技术在GSM-R网络E接口的应用，包括了案例设计、测试环境的搭建、实例分析、异常情况及解决方案。然后阐述了上述人工驱动测试方法的缺陷，指出消除缺陷的首要问题是对其形式化描述，随后介绍了通信多端口状态机的概念，并给出了一种组呼业务的互操作形式化模型。
本文提出的案例设计方法和对测试技术的相关研究有助于更好地进行互联互通测试工作的开展。
The objective of GSM-R network development is to establish a unified national mobile telecommunications network in China, and the equipment interoperability between the different manufacturers is a prerequisite for achieving goals. Research on interoperability testing technology is the foundation to finish the testing work well. Based on GSM-R network E -interface interoperability testing, this paper do in-depth studies from the two aspects of functionality and interoperability.
On the aspect of functional testing, this paper represents the concept of functional testing and focuses on the functional test suite design. Based on the in-depth study of GSM-R network E-interface services and considering the completeness and redundancy of the test suite, equivalence class method is used to design the test suite, and then an analysis of its inadequate is conducted and a new design method is proposed .The two methods are compared and a suggestion on how to design a GSM-R network interoperability test suite is given.
On the aspect of interoperability testing, this paper introduces the actuality of interoperability testing development and relations between interoperability test and functional test. Research the application of interoperability testing technology on the GSM-R network E-interface, including the case design, test environment configuration, analysis of test case. Then analyze the above artificial test methods' defects and point out that its formal description is the most important issue to eliminate defects, and finally introduce the concept of communication multi-port state machine and give a voice group call interoperability model.
The case design methods and testing methods in this paper contribute to a better test for interoperability testing work.
