The method for correcting the base station position provided by the embodiment of the invention is first described below.

Fig. 1 is a flow chart illustrating a base station location correction method according to an embodiment of the present invention. As shown in fig. 1, the method for correcting the base station position provided in this embodiment includes:

s102, acquiring signaling data used in a preset area, and traversing each signaling data to count the switching times between any two base stations in all base stations in the preset area;

s104, acquiring base stations with the switching times greater than the preset times from all the base stations to form a slave base station group of the first base station;

s106, respectively calculating the distance between the first base station and each slave base station in the slave base station group, recording the distance as a first data set, respectively calculating the distance between any two slave base stations in the slave base station group, recording the distance as a second data set, and judging whether the position of the first base station needs correction or not according to the first data set and the second data set;

and S108, if yes, calculating the position of the first base station according to the positions of the slave base stations in the slave base station group.

The base station position correction method provided by the invention firstly acquires signaling data of all mobile terminals in a preset area, because the signaling data of the mobile terminals has abundant data resources, the association relation between the base stations can be extracted by utilizing switching information of users, the switching relation between all the signaling data can be traversed one by one so as to count the switching times between any two base stations in the preset area, specifically, when one signaling data reflects that the mobile terminal is switched from an A base station to a B base station, the switching is recorded, and when all the signaling data are traversed, the switching times between the mobile terminals in the preset area are acquired; selecting base stations with switching times greater than preset times from all the base stations, wherein the selected base stations are frequently switched with the first base station, namely the base stations with switching times smaller than the preset times are considered to be close enough to the first base station, and the base stations with switching times smaller than the preset times are possibly switched due to reasons such as abnormal signal offset, so that the distance between the two base stations cannot be considered to be close enough if the switching times are too small, and the switching relation between the two base stations needs to be eliminated; and then respectively calculating the distance between the first base station and each slave base station in the slave base station group, recording each data into a first data group, respectively calculating the distance between any two slave base stations in the slave base station group, recording each data into a second data group, judging whether the position of the first base station needs to be corrected according to the first data group and the second data group, and when the subsequent correction is needed, correcting the position of the first base station according to the slave base station group of the first base station because the base stations in the slave base station group are base stations with a relatively close distance with the first base station, namely, calculating the position of the first base station according to the position of each slave base station in the slave base station group. According to the invention, the mutual relation among the base stations is calculated by combining the signaling data reported in the base stations with the actual site positions of the base stations, the interference base station data is deleted, the secondary base station group aiming at the main base station is established, the predicted position of the main base station is calculated according to the secondary base station group, the method has strong practicability for calculating and correcting the site positions of the base stations in the whole city level, the actual site positions of the base stations in the city can be quickly determined by calculation, the cost problem generated when the base station positions are actually acquired is avoided, and the process of acquiring the base station positions is simplified.

The method avoids the interaction information of the base stations collected in the field, and improves the automation level of the position update of the base stations.

Specifically, during the communication process of the mobile terminal, because the coverage areas of the base stations are partially overlapped or are relatively close, if the two base stations are switched, the distance between the two base stations is sufficiently close, each slave base station in the slave base station group corresponding to one master base station is sufficiently close to the corresponding slave base station, and the position of the master base station is determined according to the positions of surrounding slave base stations in the subsequent correction process; in addition, all the base stations in the preset area have the slave base stations with the switching relation, namely one base station can be used as the slave base station of other base stations and also can be used as the master base station.

If Lac1/Ci1 and Lac2/Ci2 exist, the number of switching times in this record is increased by 1, and if not, this data is inserted in the record table, and the number of recording times is set to 1.

In the base station handover relation table, ID indicates the number of signaling data, olac is denoted as a source location area, oci is denoted as a source cell, dlac is denoted as a destination location area, dci is denoted as a destination cell, one base station is identified together with the cell by the location area, for example Lac1/Ci1 identifies only one base station, and Num is denoted as the number of times (i.e. including the handover direction) that the base station identified by the source location area/source cell in the signaling data is handed over to the base station identified by the destination location area/destination cell. In the subsequent statistical process, the base station of the source location area/source cell identifier is used as a main base station; the destination location area/destination cell identified base station acts as a slave base station.

When forming a complete base station switching relation table, the steps are repeated until all signaling data are traversed, and a final base station switching relation table is formed.

It is conceivable that for the selection of the preset number of times, the Num field is calculated from the base station handover relation table, if Num >10 times, the handover record is kept, and if Num <10 times, this handover relation is deleted.

In one embodiment of the present invention, preferably, after the step of acquiring, from all the base stations, the base stations having the number of handovers with the first base station greater than the preset number of times to compose the slave base station group of the first base station, it includes: traversing all base stations to generate a base station master-slave relationship table for each base station of all base stations.

In this embodiment, after the slave base station groups constituting the first base station, all base stations are traversed to generate a base station master-slave relationship table for each of all base stations. Namely, each base station is selected as a slave base station group formed when the master base station is selected, and the positions of the master base stations are verified one by one according to each slave base station group.

Specifically, according to the base station switching relation table data, selecting all base stations (marked as slave base stations) with switching relation of the base station according to a source position area/source cell (marked as a master base station), establishing a master-slave relation of each base station, and organizing and storing the master-slave relation of the base stations according to a master-slave relation table, wherein the master-slave relation table of the base stations is shown in the following table 2:
