A Cell Outage Compensation Method Based On Aerial Base Station

With the rapid development of mobile Internet business,the data traffic of mobile users has shown an exponential growth trend.Nowadays,research on the ultra-dense seamless coverage technology implemented by the Small Cell(SC)has drawn great attention in the industry.However,small cellular networks are often densely populated in macro-cellular overlay networks to create multiple coverage effects for users.In this context,the interruption of the micro-cells will be hard to detect immediately,resulting in the user experience being impacted.In addition,when the cell is interrupted and compensated,due to the difficulty and cost of deployment of the terrestrial base station,especially for the disaster area and the burst large traffic area,it is difficult to quickly cover the area signal by temporarily setting up the terrestrial base station capacity to be compensated.Based on this problem,this paper presents a cell-break anomaly detection mechanism based on handoff statistics in 5G Hierarchical Heterogeneous Network scenario.Aiming at the abnormal cell,a method of cell signal compensation using air base station is proposed.Firstly,on the problem of interrupt detection,we use the classification algorithm of machine learning in the hierarchical heterogeneous scenario to mine the anomalies according to the cell-level handover statistics,so as to locate the interrupted cells.Secondly,in order to enhance the performance of network coverage and capacity,the air base stations are used to compensate for the interruption of these cells.The air base station channel propagation model and ergodic capacity model are established to compensate for the user services in the abnormal cells.In short,this article follows the current trend of new wireless communications technology,in view of the rapidly growing business needs of communication quality.In 5G ultra-dense cell coverage scenarios,to achieve effective detection of disrupted cells,we ultimately proposed a self-healing mechanism based on the Air base station network.
