In reality, there are a large number of longitudes and latitudes of the base stations to be calibrated. One calibration method currently existing is field surveying, that is, a user performs station-up checking for each base station, and even needs to coordinate the property station-up to perform field surveying, which has the following problems:

1) The batch verification cannot be performed, and the verification needs to be performed one by one, so that the verification time is long.

2) When the user is on the station, the user needs to coordinate in multiple directions due to objective reasons (such as electric charge delinquent) or property incompatibility, so that the checking efficiency is low.

And the KPI is the telephone traffic switching times between the cell covered by the target base station and the adjacent cell, namely the telephone traffic switching times between the cell covered by the target base station and the adjacent cell. The neighbor cells with the switching times of the source cell larger than the corresponding preset threshold value can also be neighbor cells with the switching times in the first few bits. The first number may be set as desired.

The cells covered by the target base station are a, b, c, d cells, b cells are selected as source cells, and 10 adjacent cells closest to the switching are taken as first number of adjacent cells closest to the source cells according to acquired KPI of the switching between the b cells and the adjacent cells.

It should be noted that the first number of values in the single carrier scenario and the multi-carrier scenario are different, for example, the first number of values in the single carrier scenario is 5, the first number of values in the dual carrier scenario is 10, and the first number of values in the three carrier scenario and above is 15.

If 2 cells covered by the target base station are in the selected first number of adjacent cells, 8 adjacent cells of the second number are obtained. And the base stations corresponding to the 8 adjacent cells are A, B, C, D (different cells exist and correspond to the same base station), and the A, B, C, D base station is a handover close adjacent base station of the b cell.
