TETRA数字集群系统多业务交互测试的研究

Research on Multiservice Interactive Testing in TETRA Digital Trunking System

为解决当前TETRA多业务交互测试领域中测试琐碎、复杂、效率低下、正确率偏低等问题,提出了一种使用TTCN-3语言实现集群通信系统的多业务交互测试方案。首先介绍了测试系统框架、原理;然后阐述了开发测试流程,并对多业务交互抽象测试例中的设计难点进行了详细说明;最后对测试结果进行分析,并举例说明了多业务交互测试的作用。通过此方案可以验证多业务交互行为是否符合协议的一致性要求,检验不同厂家的终端和网络设备是否符合标准。

In order to solve problems including Igsting trivial, complexity, inefficiency and low correct rate in the current TETRA multiservice interactive testing field, a multiservice interactive testing scheme of trunking communication system by using TTCN-3 language is proposed. The framework and principles of testing system are firstly introduced, and then the development and testing process is given. While the design difficulties of multiservice interactive abstract testing are illustrated in detail. Finally, the testing results are analyzed and the function of multiservice interactive testing is illustrated by some examples. The testing scheme can verily whether multiservice interactive behaviors are consistent with protocol, and check whether terminals and network equipments offered by diferent manufacturers meet the standards.
