随着 3G技术的进一步发展和成熟 ,现在电信和其他数据通信技术面临着一个进一步融合突破的时代。 3G的发展更推动了全球实现无缝漫游 ,互连互通的需求。这样就为全球的 3G设备制造商提出了更高的要求。但由于各协议实现厂家对协议的不同理解 ,通信设备的协议非一致性问题将日趋严重 ,为了检查各个不同生产厂家的实现是否与标准文本相一致 ,进而确保不同厂家的 3G协议实现之间能够互操作 ,一致性测试是非常必要的。文中根据笔者在 3GPP中T1信令组工作背景为基础 ,并以MAC部分测试结构和方式为例 ,给出了形式化的TTCN格式。全面的论述了 3GPP中的协议一致性测试过程
With the further development and maturity of 3G technology, telecommunications and other data communication technologies are now facing an era of further convergence and breakthrough. The development of 3G has also promoted the global demand for seamless roaming and interconnection. This puts higher demands on the global 3G equipment manufacturers. However, due to different agreements between manufacturers to realize different understandings of the protocol, communication protocol inconsistencies will be aggravated. In order to check whether the implementation of different manufacturers is consistent with the standard text, thus ensuring that different manufacturers can achieve between the 3G protocol Interoperability, consistency testing is very necessary. In this paper, based on the author’s working background in T1T signaling group in 3GPP and taking the test structure and mode of MAC part as an example, a formal TTCN format is given. Comprehensive discussion of the agreement in 3GPP protocol testing process
