北斗辅助定位的终端协议一致性测试TTCN-3代码设计

摘要

随着LTE网络的大规模商用，为了配合国内LTE多模终端支持我国自行研制的北斗卫星导航系统的需求，3GPP Release 12在原有A-GNSS定位技术的基础上引入了辅助的北斗定位技术A-BDS并完成了A-BDS相关的终端一致性测试标准代码的开发工作。主要介绍了A-BDS的LTE多模终端协议一致性的测试模型和TTCN-3代码的设计。%With the large scale business application of LTE, to accommodate the requirement of LTE UE to support BeiDou navigation satellite system in China, assisted A-BDS was introduced since 3GPP Release 12, and the related UE conformance testing standard code design was ifnished. In this paper, A-BDS test models structure and TTCN-3 design were introduced.
