摘要

网络功能虚拟化（NFV）技术是近年兴起的网络技术，通过将具有特定网络功能的软件搭载在通用硬件服务器上，实现软件与硬件解耦。将网络功能虚拟化技术应用到无线接入网络中，将其部分网络功能虚拟化，可以有效地降低网络运营成本和硬件设备制造成本，提高网络部署的灵活性，满足移动用户的质量体验（QoE）需求。为了深入了解NFV在无线接入网络中的发展现状与趋势，从3个角度对现有研究进行综述，包括无线接入网络中网络功能虚拟化的相关标准研究现状、无线网络功能虚拟化技术的体系架构以及无线接入网络中网络虚拟化资源分配的问题，并提出了网络功能虚拟化在无线网络中应用存在的挑战。

Abstract

Network function virtualization (NFV) is a kind of new network technology rising in recent years. It realizes the decoupling of software and hardware by running the software which has specific function on a general-purpose hardware server. Applying the NFV to the radio access network could virtualize some of the radio access functions. It can reduce the operating costs and capital costs efficiently

and improve the flexibility of the network deployment. It also can satisfy the quality of experience of mobile users. In order to review the work that contribute to the current situation of NFV in radio access network

three perspectives were reviewed

including research on the related standards of network functional virtualization in RAN

network architecture of network function virtualization

and the resource allocation of network function deployment. Finally

the challenges of network function virtualization applying in wireless network were proposed.
