摘要:

伴随着5G网络的大规模快速建设,运营商乃至整体通信行业的能耗压力在同步凸显。通过节能降耗实现行业可持续发展成为当前5G网络发展的新研究方向。以小区物理资源块(physical resource block,PRB)利用率为负荷评估指标,对小区指标进行深度特征提取,提出了一套深度卷积神经网络和长短期记忆(DCNN-LSTM)深度学习算法模型实现PRB利用率未来值预测,进一步结合小区瞬时任务中大小包比例,对各种基站设定动态化的节能策略。并引入网络能耗管理网元,对整体5G接入网络的能耗进行动态化统一管理,在保障无线网络服务质量的基础上,实现了5G基站的智能化节能运作。

关键词: 5G基站节能, 改进型LSTM算法, 5G系统设计

Abstract:

With the rapid construction of the 5G wireless communication network, the energy consumption pressure of operators, and even the overall communication industry, is simultaneously highlighted.Achieving sustainable development of the industry through energy conservation and consumption reduction has become a new research direction for the current 5G network development.Taking the PRB rate as the load evaluation index, LSTM model was improved by using DCNN to extract the depth feature of the cell’s indicators.A set of DCNN-LSTM deep learning model that could predict the future value of PRB rate was proposed.On the basis of the improved algorithm, the network topology of the current 5G access network was optimized.An additional network element and its working system were designed.An intelligent energy-saving system, which ensured the network experience, of 5G base stations was realized.

Key words: 5G base station energy saving, improved LSTM algorithm, 5G system design
