云无线接入网络(C-RAN)为蜂窝网络部署、管理和演进提供了一种革命性的方法。此外，软件定义无线电(SDR)和网络技术的进步使通过云交付软件定义的一切成为可能。资源将利用抽象、虚拟化和整合技术进行池化和动态分配；流程将使用通用应用程序编程接口实现自动化；网络功能和服务将通过协调器以编程方式提供。OOCRAN是一个基于ETSI提出的NFV MANO架构的软件框架。它为整个无线基础设施提供协调层，包括硬件、软件、频谱、前端通道和回程。OOCRAN通过合并无线电通信层及其管理依赖项来扩展现有的NFV管理框架。然后，无线基础设施提供商可以动态地向无线服务提供商提供虚拟无线网络。试验床的物理基础设施是围绕一个计算集群构建的，该集群执行开源的SDR库并连接到基于SDR的远程无线电报头。我们演示了OOCRAN的操作，并讨论了动态LTE小蜂窝网络部署的时间含义。
The Cloud radio access network (C-RAN) offers a revolutionary approach to cellular network deployment, management and evolution. Advances in software-defined radio (SDR) and networking technology, moreover, enable delivering software-defined everything through the Cloud. Resources will be pooled and dynamically allocated leveraging abstraction, virtualization, and consolidation techniques; processes will be automated using common application programming interfaces; and network functions and services will be programmatically provided through an orchestrator. OOCRAN, oocran.dynu.com, is a software framework that is based on the NFV MANO architecture proposed by ETSI. It provides an orchestration layer for the entire wireless infrastructure, including hardware, software, spectrum, fronthaul and backhaul. OOCRAN extends existing NFV management frameworks by incorporating the radio communications layers and their management dependencies. The wireless infrastructure provider can then dynamically provision virtualized wireless networks to wireless service providers. The testbed's physical infrastructure is built around a computing cluster that executes open-source SDR libraries and connects to SDR-based remote radio heads. We demonstrate the operation of OOCRAN and discuss the temporal implications of dynamic LTE small cell network deployments.
