entering a first energy saving mode threshold: the method comprises the steps of including threshold sets such as PRB utilization rate, user number, throughput and the like of a service cell and an adjacent cell; (for example, PRB utilization rate: 40%, user number: 50, throughput: 20M uplink, 200M downlink; etc.) can be set.
Threshold 2 for entering the first energy saving mode: the method comprises the steps of including threshold sets such as PRB utilization rate, user number, throughput, RSRP and the like of a service cell and an adjacent cell; (for example, PRB utilization rate is 20%, user number is 20, throughput is 10M uplink and 100M downlink, and RSRP of all UE neighbor cells is larger than-110 dbm).
Entering a third mode threshold: the method comprises the steps of including threshold sets such as PRB utilization rate, user number, throughput and the like of adjacent regions; (for example, PRB utilization rate is 10%, user number is 10, throughput is 5M for uplink and 50M for downlink).
Exiting the first energy saving mode threshold: the method comprises the steps of including threshold sets such as PRB utilization rate, user number, throughput and the like of a service cell and an adjacent cell; (for example, PRB utilization rate: 80%, user number: 80, throughput: uplink 60M, downlink 400M).
