摘　　要：构建了NB-IoT网络与需求满足度的评估体系,该体系基于有4G覆盖区域的A-GPS MR数据和无覆盖区域的仿真预测,考虑了网络制式的覆盖差异因子、不同典型场景覆盖差异因子及不同承载频率的覆盖差异因子,形成20×20 m的、可迭代更新的底层NB-IoT网络覆盖数据库,并利用最小投资算法成功实现NB-IoT网络与市场满足度评估以及最小开站规模评估,实现网络覆盖评估和投资效益最大化,加快5G的mMTC场景应用业务推广。It constructs an evaluation system of the NB-Io T network and demand satisfaction. This system is based on the A-GPS MR data of 4G coverage area and simulation prediction of no coverage area. Considering the coverage difference factor of network format,coverage difference factor of different typical scenarios and coverage difference factor of different carrying frequencies,it forms a 20×20 m,iteratively updated underlying NB-IoT network coverage database. The minimum investment algorithm is used to realize the evaluation of NB-IoT network and market satisfaction,as well as the evaluation of minimum startup scale,so as to maximize the network coverage and investment benefits,speed up 5G m MTC scenario application business promotion.
