随着连接设备和新兴数据需求应用的激增，预计到2020年，移动的数据流量将增长1000倍。为了应对这种数据爆炸的挑战，工业界和学术界已经开始研究和开发5G无线网络，设想其满足大量数据流量，同时提供无处不在的连接并支持具有不同服务质量（QoS）要求的各种应用。为了支持预期的移动的数据的大规模增长，预计将在室内和室外部署大量的小型小区，从而产生异构网络（HetNet），这被认为是通往5G的关键路径。对于这种大规模的HetNet，网络运营商在运营和管理、具有成本效益的小小区部署以及小区间干扰缓解方面面临许多严峻的挑战。为了解决这些问题，引入了基于云的平台，旨在简化部署，运营和管理，并促进网络的全天候优化，为5G的发展铺平道路。提供了两个案例研究来说明基于云的架构的好处。最后，提供了相关的标准化活动，并讨论了成功开发5G所必需的一些研究课题。
With the proliferation of connected devices and emerging data-hungry applications, the volume of mobile data traffic is predicted to have a 1000-fold growth by the year 2020. To address the challenge of this data explosion, industry and academia have initiated research and development of 5G wireless networks, which are envisaged to cater to the massive data traffic volume, while providing ubiquitous connectivity and supporting diverse applications with different quality of service (QoS) requirements. To support the expected massive growth of mobile data, a large number of small cells are expected to be deployed indoors and outdoors, giving rise to heterogeneous networks (HetNets), which are considered to be the key path toward 5G. With such large-scale HetNets, network operators face many serious challenges in terms of operation and management, cost-effective small cell deployment, and intercell interference mitigation. To deal with those issues, a cloud based platform is introduced, aiming to simplify the deployment, operation and management, and facilitate round-the-clock optimization of the network, to pave the way for the development of 5G. Two case studies are provided to illustrate the benefits of the cloud based architecture. Finally, the related standardization activities are provided and some research topics essential for a successful development of 5G are discussed.
