MR.LteScRSRP2,……,MR.LteNcRSRPi-MR.LteScRSRPi}。
If the sampled point of (second threshold) is greater than 6 (third threshold values) 80% in set B, just can be by this cell alien frequencies A2 liter
For Nr-135.
In one possible implementation, when the quantity for the second difference greater than second threshold determined is less than or equal to
When third threshold value, the A2 to be optimized is determined as to the A2 optimal value of the cell to be optimized.
Specifically, if 80% sampled point is not more than 6 in set B, the A2 for keeping the OMC in cell to be optimized to configure
Value.
In one possible implementation, the method in the present invention further includes output prioritization scheme.At MRE data
Principle is managed, convergence processing is carried out with cell ID, the A2 thresholding Optimizing Suggestions value of each ID cell is provided, generates final optimization and build
View scheme.For example, providing the A2 Optimizing Suggestions of all cells in the whole network.Fig. 3 shows provided in an embodiment of the present invention based on MRE
