摘　　要：基于蜂窝的窄带物联网(NB-IoT)技术在复杂应用环境中往往会出现连接不稳定、时延过长等问题。为解决由APN参数设置导致的NB-IoT业务问题,优化用户体验,对不同种类的NB-IoT业务中包括APN参数在内的一系列关键参数进行了研究。分析了NB-IoT业务的组网架构,通过对比不同参数设置对固定NB-IoT业务应用的影响,确定各关键参数的推荐配置值。以某智能小区内安装的NB智能门禁模组遇到的网络问题为案例,对NB-IoT的端到端业务优化工作进行分析,通过实验证明关键参数推荐配置值的有效性,为NB-IoT技术在不同垂直行业中的应用提供参考。The honeycomb-based narrowband IoT technology designed for low-power and wide-coverage applications has problems such as unstable connections and long delays in complex practical applications.A series of key parameters including APN parameters in different types of NB-IoT services are studied in order to solve the NB-IoT service problems caused by APN and other parameter settings in actual applications and optimize user experience.The network architecture of NB-IoT service was studied.The recommended configuration values of each key parameter were determined by comparing the effects of different parameter settings on the application of fixed NB-IoT service.The NB-IoT end-to-end service optimization work is discussed and analyzed using the solution to the network problems encountered by the NB intelligent access module installed in an intelligent community as a case.The validity of the proposed key parameter recommended configuration values is proved,which provides a reference for the further application of NB-IoT technology in different vertical industries.
