The existing abnormal working parameter checking mode has the limitations of insufficient intelligence, insufficient precision and low efficiency, and the development of the checking work usually brings a series of operation costs such as purchase and loss of tower workers, vehicles and instruments. With the gradual expansion of the network scale, the existing abnormal working parameter checking mode can not meet the production requirement of the large-scale working parameter checking of the existing network.
Fig. 1 shows a flowchart of a method for checking latitude and longitude of a base station according to an embodiment of the present invention, where as shown in fig. 1, the method includes:
step S10, obtaining sampling point information in the UEMR data of the base station measurement report, wherein the sampling point information comprises longitude and latitude information of a sampling point and a Reference Signal Received Power (RSRP) value.
And S20, determining the sampling points of which the RSRP values are greater than the checking threshold value as checking sampling points.

And acquiring sampling points around the target base station according to the UEMR data, and determining longitude and latitude information of all the sampling points. And screening sampling points with the RSRP larger than-70 dBm, and calculating the average longitude and latitude as the virtual longitude and latitude of the target cell. Fig. 2 shows a schematic distribution diagram of sampling points around a base station according to an embodiment of the present invention, and in fig. 2, theoretically, the closer the sampling points are to the base station, the larger the RSRP value is.

Specifically, virtual longitude and latitude are calculated in different modes for different types of base stations from two remote situations and non-remote situations, and whether the remote base station is abnormal or not is judged through the virtual longitude and latitude of a remote cell; the non-remote base station calculates the longitude and latitude abnormal proportion of the base station (the proportion of the abnormal number of the longitude and latitude of different cells of the same base station to the number of all the cells of the base station):
