Fig. 2 is the flow for one Application Example of method for carrying out debugging to base station database the present invention is based on GPS positioning
Figure.The embodiment can be by a positioning error checking system as shown in Fig. 2, the Application Example includes：
210, positioning error checking system is by the mobile fine positioning platform of network side to the mobile phone in the overlay area of current area
Terminal j（I.e.：Mobile subscriber ID=j under the cell ID of current area）Carry out GPS positioning.
Positioning error checking system can be from VLR Visitor Location Register（VLR）The middle mobile use obtained in the overlay area of current area
Family ID.
220, positioning error checking system receives the GPS positioning position coordinates that mobile fine positioning platform returns（X_i_j_GPS,Y_
i_j__GPS）Afterwards, the thick platform of running fix of network side is immediately passed through to the same mobile phone terminal j in the overlay area of current area
LBS positioning is carried out, receives and records LBS position locations coordinate（X_i_j_LBS,Y_i_j__LBS）.Wherein, i is represented on the other hand
Ith of the machine terminal j in current area positions.
230, progress is continuously repeated to same mobile phone terminal j by mobile fine positioning platform and the thick platform of running fix respectively
Multiple GPS positioning and LBS positioning.
240, the GPS positioning position coordinates for representing GPS positioning result are received every time（X_i_j_GPS,Y_i_j__GPS）Afterwards,
Positioning error checking system passes through GPS positioning position coordinates（X_i_j_GPS,Y_i_j_GPS）Judge the GPS of the same mobile phone terminal j
Whether move position location.
If the GPS positioning position of the same mobile phone terminal j is moved（It is or mobile more than 20 meters）, do not continue to initiate
Location Request.
If the multiple GPS positioning position of the same mobile phone terminal j is not moved（It is or mobile less than 20 meters）, positioning
Request number of times can be more, and the debugging effect of the more embodiment of the present invention of number is better.
250, calculate average value X_j_LBS=the ∑s X_i_j_LBS/m, Y_j_LBS=of these secondary LBS position locations coordinates
∑ Y_i_j_LBS/m, i=1~m, m are the number for continuously repeating positioning.Preserve the group positioning initiation time Start_time,
Mobile subscriber ID, current area ID, the GPS positioning position coordinates of mobile phone terminal j（X_j_GPS,Y_j_GPS）, GPS positioning position
The average value of coordinate（X_j_LBS,Y_j_LBS）Etc. results to positioning error checking system in.
Since GPS location does not change substantially, GPS positioning position coordinates（X_j_GPS,Y_j_GPS）（X_i_j_GPS,
Y_i_j_GPS）In select one.
260, positioning error checking system calculates the average value of GPS positioning position coordinates and LBS sprocket bits of same mobile phone terminal j
Put position location offset distance d_j=((X_j_LBS-X_j_GPS) ^2+ (Y_j_LBS-Y_j_ between the average value of coordinate
GPS) ^2) ^ (1/2), and will position and initiate time Start_time, the mobile subscriber ID of mobile phone terminal j, current area ID, determine
Position position deviation distance d_j is preserved as a result.
270, positioning error checking system is to the corresponding mobile phone terminal weights of all other mobile subscriber ID in the ID of the current area
Multiple aforesaid operations 210~260 are completed in current area after whole mobile phone terminal scannings, and calculating is fully completed the above-mentioned behaviour of above-mentioned step
Make average value d_adv=∑ d_j/n of the position location offset distance of 210~260 mobile phone terminal, j=1~n, n is that this is current
The quantity of the effective mobile phone terminal for successfully completing aforesaid operations 210~260 in cell.
280, it is pre- that positioning error checking system judges whether the mean value d_adv of the position location offset distance of the current area is more than
If threshold value, so that it is determined that whether the base station information in the corresponding base station database in current area is wrong.
If greater than predetermined threshold value, judge that ID corresponding base station informations in the current area are wrong in base station database.It is right
In the dense distribution area of base station and countryside, the value difference of predetermined threshold value is larger.Predetermined threshold value can be chosen by the following method：
The longitude and latitude of base station where the current area is found in base station database and the neighbour nearest apart from base station where the current area
The longitude and latitude of base station is connect, takes the half of the distance of two base stations, as the covering radius r of the cell, is multiplied by being corrected with one
Number α.Wherein, correction factor α can be changed according to actual conditions are descending.In practical application, correction factor α and cell
The product of covering radius r can from big to small change between 10km to 300 meters, and it is original that the step-length of variation can change every time
1/3.The value of correction factor α is bigger, and predetermined threshold value is bigger, determine occur base station information mistake base station number it is fewer.
For the little incorrect base station information of error, if no more than predetermined threshold value, its base station information mistake can not be just determined, so as to go out
Now fail to judge.The value of correction factor α more under, predetermined threshold value is smaller, since the precision of LBS positioning itself is not high, if default threshold
Value is too small, is, for example, less than the positioning accuracy of base station, may result in the judgements of most of or whole base station information mistakes as a result, so as to
The possibility of erroneous judgement is bigger.
290, positioning error checking system performs aforesaid operations 210~280 to other cells in mobile communications network successively, from
And realize that the scanning to whole cells in mobile communications network calculates, it realizes and base station informations whole in base station database is looked into
It is wrong.
