摘要
5G接入网将是一个满足多场景的多层异构网络,能够容纳已广泛应用的各种无线接入技术和5G新空口多种接入技术。本文首先分析了5G网络四种典型覆盖场景:室外广域覆盖、室内热点覆盖、低功耗数据采集、低时延物联网控制。其次分析了5G无线网络关键性能指标:移动性、时延性、接入速率、流量密度、连接数密度、能源效率;提出了5G无线网络架构设计原则,既要保证网络具有高度的智能性、网元和架构配置的灵活性,又要保证建设和运维成本的高效性。最后,我们给出了一个具体的5G无线接入网络架构设计方案。
5G access network will be a satisfying scene multilayer heterogeneous network,has been widely used to accommodate various wireless access technologies and5G new interface multiple accesstechnology.In this paper,four kinds of typical coverage scenarios of5G network are analyzed,such as outdoor wide area coverage,indoor hot spot coverage,low power consumption data collection,low latency networked control.Secondly,analyzes the key performance indexes of5G wireless network:mobility,time delay,access speed,traffic density,connection number density and energy efficiency;put forward the5G wireless network architecture design principles,both to ensure that the network is highly intelligent,network architecture and configuration flexibility,but also to ensure the efficiency of construction and maintenance costs.Finally,we give a detailed design scheme of5G wireless access network architecture.
