It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Example 1

Example 2

Because all the UEs in the cell can meet the system requirements by using frequency division scheduling when the resource utilization rate of the LTE cell is not high, and space division scheduling is not needed, and when the resource utilization rate of the cell is high, the QoS requirements of more UEs in the cell may not be met or part of the later-accessed UEs cannot be admitted by continuously using the frequency division scheduling, a strategy for starting space division scheduling is adopted when the resource utilization rate of the cell is high, so that the throughput of the cell and the satisfaction of the UEs can be improved.
Based on the analysis, firstly, counting the occupation situation of the RBs in the cell in the preset time period, calculating the total RB quantity in the time period, and calculating the utilization rate of the RBs in the time period; counting the traffic condition of network UE in a preset time period and the traffic demand condition of the UE, calculating the air interface bandwidth in the time period, and calculating the traffic demand ratio of the hotspot area in the time period; and calculating the sum of GBRs of all the UEs in a preset time period, comparing the sum with air interface resources, and calculating whether the phenomenon of network congestion possibly occurs.
After counting the parameters, if the occupancy rate of the total RB resource is judged to be larger than a preset judgment threshold, the user flow demand of the hot spot area is judged to be larger than the judgment threshold of the threshold, the GBR sum of the users is larger than the preset judgment threshold, and the number of the UE of which the QoS satisfaction does not reach the preset judgment threshold is larger than the preset threshold, the method enters a space division scheduling process and carries out space division scheduling on the users of which the flow demand of the hot spot area is larger than the preset judgment threshold and the users of which the QoS satisfaction does not reach the preset judgment threshold.
