摘要
5G RAN与核心网属于新型化架构。5G对于同步、切片、时延以及宽带等需求,针对承载网提出了全新标准。4G承载网要逐步朝着5G承载网发展,业界也提出了IP RAN、SPN与OTN等技术方案。国内运营商针对5G承载网的架构与需求基本趋于同化,技术方案上则依据目前的网络现状与未来5G业务的发展趋势进行自主化选择。鉴于此,将主要分析5G承载网的网络架构和关键技术。
5G RAN and core network belong to a new architecture.For synchronization,slicing,delay and broadband requirements of 5G,a new standard for bearer network is proposed.In order to develop the 4G bearer network towards 5G bearer network gradually,the industry has also proposed some technical schemes such as IP RAN,SPN and OTN.Domestic operators basically tend to converge in terms of the architecture and requirements of 5G bearer network,and make independent choices according to the current network situation and the future development trend of 5G services.In view of this,we will mainly analyze the network architecture and key technologies of 5G bearer network.
