摘要:

为了降低前传(fronthaul)链路开销、避免传统云无线接入网基带单元池中无线信号处理大规模/高实时要求、充分利用边缘网络设备的计算和存储能力,提出了雾无线接入网络(fog computing based radio access network,F-RAN),作为异构云无线接入网络的演进。F-RAN的核心是利用用户和边缘网络设备的计算和存储功能,进行本地业务分发、分布式信号处理和分布式资源管理等。详细介绍了F-RAN的系统架构、关键技术及未来需研究的问题。

Abstract:

To reduce the burden of fronthaul link,avoid large-scale wireless signal processing in centralized baseband unit(BBU)pool,and take full advantage of processing and storage capabilities in edge devices,a fog computing based radio access network(F-RAN)was presented as an evolution form of heterogeneous cloud radio access networks.The core idea of F-RAN was to take full advantage of processing and storage capabilities in edge devices which could achieve the local distributed content delivery,the local distributed collaboration radio signal processing and the local distributed cooperative radio resource management functions.System architectures of F-RAN,promising key techniques,and researching open issues of F-RAN were discussed in detail.

Key words: fog computing based radio access network, fog computing, edge cloud, edge caching
