摘要
随着5G商用的全面开展,5G无线站点数目急剧增加,5G核心网需分层部署在区域/省/地市数据中心,以及数据中心规模化发展,导致能耗问题日益凸显。基于全网能耗主要占比,调研5G接入网络、核心网络和数据中心的能源效率评估方法。介绍了AI使能的基站节能技术及试点应用方案、AI应用于5G核心网的节能方式、AI使能的数据中心节能技术和试点应用方案,探讨了节能技术的挑战和未来的研究方向。对整体通信系统节能技术的总结和展望,有助于提高对能源效率和绿色网络发展的认识。
With the development of 5G commercialization,the number of 5G wireless base station sites has increased sharply,5G core networks need to be deployed in regions/provinces/cities data centers,as well as the data centers were developing on a larger scale,the problem of energy consumption was becoming increasingly prominent.Based on the main proportion of energy consumption in the whole network,the energy efficiency evaluation methods of 5G access network,core network and data center was investigated.The AI-enabled energy-saving technology of base stations and pilot application scheme,5G core network energy-saving methods by using AI,as well as the AI-enabled energy-saving technology of data centers and pilot application scheme were introduced,and the challenges and future research directions of energy-saving technology were finally discussed.The summary and prospect on the energy-saving technology of the overall communication system,will help to improve the understanding of energy efficiency and green network development.
