摘要:

云无线接入网络(C-RAN)为蜂窝网络的部署、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提供软件定义的一切成为可能。将利用抽象化、虚拟化和整合技术汇集和动态分配资源;将使用通用应用程序编程接口实现流程自动化;将通过协调器以编程方式提供网络功能和服务。OOCRAN,oocran.dynu.com,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了一个协调层,包括硬件、软件、频谱、前传和回传。OOCRAN通过合并无线电通信层及其管理依赖性来扩展现有的NFV管理框架。无线基础设施提供商然后可以动态地向无线服务提供商提供虚拟化无线网络。该测试平台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SDR库并连接到基于SDR的远程无线电头。我们演示了OCCRAN的操作,并讨论了动态LTE小小区网络部署的时间影响。

英文摘要:

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.
