虽然云无线接入网（c - ran）的概念为未来网络环境提供所需的服务质量（QoS）提供了一个有希望的解决方案，即超过10 Gbps的容量，小于1毫秒的延迟，以及众多设备的连接，但它仍然容易受到体验质量（QoE）问题的影响。到目前为止，只有少数研究者考虑了基于质量质量的c - ran的设计和运行。本文描述了我们设想的基于无源光网络（pon）的C-RAN，该网络利用光纤供电（PoF），安装成本低，能够在没有外部电源的情况下为远程无线电头（RRH）提供通信服务，并描述了设想网络的QoE要求。为了满足预期网络中所有用户的QoE，提出了有效的网络设计和运营方法。我们提出的设计和操作方法演示了如何构建预想的网络，即RRHs和光线路终端（olt）的数量，以及RRHs的睡眠调度以实现节能的光功率传输。
While the concept of Cloud Radio Access Networks (C-RANs) presents a promising solution to provide required quality of service (QoS) for the future network environment, i.e., more than 10 Gbps capacity, less than 1 ms latency, and connectivity for numerous devices, it is still susceptible to quality of experience (QoE) problems. Until now, only a few researchers considered the design and operation of C-RANs based on QoE. In this article we describe our envisioned C-RAN based on passive optical networks (PONs) exploiting power over fiber (PoF), which can be installed with low installation cost and is capable of providing communication services without external power supply for remote radio head (RRH), and describe QoE requirement on the envisioned network. For all users in the envisioned network to satisfy their QoE, effective network design and operation approaches are then presented. Our proposed design and operation approaches demonstrate how to construct the envisioned network, i.e. the numbers of RRHs and optical line terminals (OLTs), and sleep scheduling of RRHs for an energy-efficient optical power transmission.
