Abstract

Virtualization is a key feature in Cloud Radio Access Network (C-RAN). It can help to save costs since it allows the use of virtualized base stations instead of physically deployment in different areas. However, the creation and management of virtual base stations pools is not trivial and introduces new challenges to C-RAN deployment. This paper reports a method to orchestrate and manage a container-based C-RAN. We used several instances of the OpenAirInterface software running on Docker containers, and orchestrated them using Kubernetes. We demonstrate that using Kubernetes it is possible to dynamically scale remote radio heads (RRHs) and baseband units (BBUs) according to requirements of the network and parameters such as the server resources usage.

基于Docker、Kubernetes和OpenAirInterface的虚拟化C-RAN编排
虚拟化是云无线接入网(C-RAN)的一个关键特性。它可以帮助节省成本,因为它允许使用虚拟化的基站,而不是在不同的区域进行物理部署。然而,虚拟基站池的创建和管理并非易事,这给C-RAN部署带来了新的挑战。本文报告了一种编排和管理基于容器的C-RAN的方法。我们使用了运行在Docker容器上的OpenAirInterface软件的几个实例,并使用Kubernetes对它们进行了编排。我们演示了使用Kubernetes可以根据网络需求和服务器资源使用等参数动态扩展远程无线电头(RRHs)和基带单元(BBUs)。
