IP RAN需要适配5G网络架构的变化,满足5G定义的eMBB、uRLLC、mMTC等多业务差异化承载需求。“大带宽、低时延、灵活连接”网络能力是面向5G承载的IP RAN的基本要求。首先分析了5G业务需求和网络架构特性,提出面向5G承载的IP RAN演进方案,然后对5G承载的IP RAN关键技术进行研究和试验验证,为5G大规模商用化部署提供支撑和建议。
IP RAN need to adapt to the changes of 5G network architecture to meet the differentiated bearing requirements of eMBB
uRLLC and mMTC services defined by 5G.The network capabilities of “large bandwidth
low latency
flexible connection” are the basic requirements of IP RAN for 5G bearer.Firstly
the characteristics of 5G services and network architecture were analyzed
and the 5G-oriented IP RAN evolution scheme was proposed.Then
the key technologies of 5G-beared IP RAN were investigated and tested to provide support and suggestions for large-scale commercial deployment of 5G.
