蜂窝物联网核心网目标架构演进探讨

物联网存在面向2G、4G、窄带物联网(narrow band Internet of things,NB-Io T)的传统专用核心网以及面向5G的toB物联网核心网。随着网络的进一步云化演进,为简化网络、增强能力、提升效益、方便运维,需要明确面向未来的物联网核心网目标架构。基于现网存在的问题,结合网络演进驱动力,对物联网网络演进目标架构、演进策略以及业务解决方案进行了分析和探讨,以此为运营商物联网规划建设提供参考。

Discussion on the evolution of architecture of the core network of cellular Internet of things

At present, there are two Internet of things networks facing 2G, 4G, NB-IoT and facing toB core networks.In order to simplify the network, enhance the capability, enhance the benefit, and facilitate the operation and maintenance, it is necessary to define the target architecture of 5G-oriented Internet of things core network.Based on the existing network problems and combined with the driving force of network evolution, the network evolution target structure, evolution strategy and service solution were analyzed and discussed.It provides a reference for operators to plan and construct the Internet of things.
