摘要
由我国首次提出的"双碳"目标(即"碳达峰"与"碳中和"),是"十四五"规划中的重要布局,也是未来移动通信网络实现绿色、可持续发展的关键目标,更是奠定我国国际碳资产定价权与世界碳交易平台的基础.其中,实现绿色通信的难点在于保持业务量增长的同时,降低网络能耗及碳排放.本文从移动通信网络侧节能减排的角度和通信网与多能能源网融合架构的角度对绿色通信技术展开研究.研究结果表明,实现绿色通信技术的关键在于进行网络资源、能量资源与业务分布的相互匹配,而现有技术仅能实现网络资源与业务分布的单向匹配,或能量资源与业务分布的单向匹配.基于此,本文提出一种通信、感知和能量融合的原生绿色网络架构,该架构具备能量感知与业务感知能力,支持网络资源、能量资源与业务分布双向匹配方法,通过消除业务分布与能量分布的随机性与突发性,实现业务量持续增长的同时,显著降低移动通信网络侧耗能及碳排放.
The“carbon peaking”and“carbon neutrality”target is a crucial strategic layout for China’s 14th Five-Year Plan.It not only represents the fundamental strategic objective towards the green and sustainable development of mobile communication network in the future,but also will establish the Chinese leadership in international carbon asset pricing and the global carbon trading platform.However,the key challenge in achieving green communication lies in reducing energy consumption and carbon emissions of network while maintaining traffic flows growth.On the one hand,this article surveys green communication technologies from the perspective of energy saving and carbon emissions reducing.On the other hand,green communication technologies under the integration architecture of communication network and multi-energy network are investigated.The research results show that the key of realizing green communication depends on mutually matching among network resources,energy distribution,and traffic distribution.But existing technologies can only realize one-way matching between network resources and network distribution,or one-way matching between energy distribution and service distribution.In light of this,this article proposes an intrinsic green-native network architecture characterized by the integration of communication,sensing,and energy,which enables energy sensing and traffic sensing,supporting dual-way matching among network resources,energy distribution,and traffic distribution.Through mitigating the randomness and bursts of traffic and energy distribution,this architecture achieves the continuous increasing of traffic flows while significantly reducing energy consumption and carbon emissions of mobile communication network.
