摘要
5G需要实现数十倍于4G指标的性能,包括1Gbit/s的用户体验速率、1×10^6/km^2的连接数密度和毫秒级别的端到端时延,而组网方式的选择直接影响到5G的性能。因此,运营商在进行5G网络建设前,如何选择独立组网和非独立组网方式及相应的演进路径是需要首先重点考虑的问题。下面详细研究了5G备选组网方式及几种组网方式的优劣势,并且分析了运营商可选择的5G演进路径,能够为运营商组网方式及演进路径的选择提供参考意见。
5G needs to achieve several dozen times the performance of 4G,including 1 Gbit/s user experience rate,1×10^6/km^2 connection density and millisecond level end-to-end delay.However,the choice of networking mode would directly affect the performance of 5G.Therefore,before the construction of 5G network,how to choose independent networking(SA)and non-independent networking(NSA)modes and the corresponding evolution paths by operators are the key issues that need to be considered first.The advantages and disadvantages of the 5G alternative networking mode and several networking modes are discussed in detail,and the possible 5G evolution paths that operators may choose analyzed,and all this can provide a reference for operators to choose networking modes and evolution paths.
