摘　　要：阐述了基于5G移动网络网络切片技术的关键通信技术演进,基于B-TrunC标准和3GPP宽带关键通信标准,构建了独立建网模式和结合公网模式两种宽带关键通信网络的演进模式,分析和比较了各种组网模式性能,最后提出了基于宽窄带融合、逐步过渡的演进方式,实现现有窄带专业通信网络向宽带关键通信网络的演进。This paper provides the evolution of critical communication technology based on network slicing technology in 5G Mobile Network.Based on the B-TrunC standard and 3GPP broadband key communication standard,two evolution modes are constructed for broadband key communication networks,i.e.standalone networking mode and joint public network mode,and then the performances of various networking modes are analyzed and compared.Finally,the evolution mode based on wideband and narrowband fusion and gradual transition is proposed to realize the evolution from the existing narrowband professional communication networks to broadband key communication networks.
