| 摘 要： | 5G系统更大的频宽和复杂的空口技术不可避免地带来总体能耗的显著增长，因此移动网络的绿色节能引发了广泛的关注。5G与4G的长期共存以及5G的低频广覆盖和高频大带宽特性，使得不同类型的业务可以由5G的不同载波或者4G分别承载。基于以上考虑，提出了基于核心网分析和决策的5G网络智能调度方案，可以将不同类型的业务调度到不同的接入方式和工作频段上进行承载，从而实现业务保障和绿色节能。仿真结果表明，与现有的无线调度方案相比，5G网络智能调度在保障服务质量的同时，节能效果更具优势。最后，介绍了5G网络智能调度国际标准化工作进展。

| Abstract: | Larger bandwidth and complex technology of the 5G networks inevitably bring a significant increase in overall energy consumption, so green energy-saving of mobile networks has attracted widespread attention.The long-term coexistence of 5G and 4G, as well as the wide coverage of low-frequency and the wide bandwidth characteristics of high-frequency of 5G, enable different types of services to be carried by different carriers of 5G or 4G respectively.Based on the above considerations, a 5G network intelligent scheduling scheme based on corenetwork analysis and decision was proposed, which could schedule different types of services to different radio access and frequencies for carrying, so as to achieve service assurance and energy-saving.Simulation results reveal that, compared with the existing schedule scheme within radio access network, 5G network intelligent scheduling has advantages in energy saving while ensuring quality of service.Finally, the progress of international standardization of 5G network intelligent scheduling was introduced. |
