Whether the overlay area of base station is reasonable, if there are problems that covering and covered.
By LTE MR data obtain customer position information method be：The first step：Need to gather user by OMC-R
The MR test report reported, sampling period and data format according to MR test report, test report has the data of three types,
Respectively MRO MRS MRE files, wherein MRO files for reporting of user sampled point granularity measurement file, contain the time
Lead TADV and antenna angle of arrival AOA.Second step：From TADV and AOA definition, TADV determines user and base
The distance stood, AOA determines the angle of user and direct north, it is possible thereby to the position of the sampled point of user is calculated and positions,
The longitude and latitude for extending TADV distances on direct north is namely calculated, thus, customer location realizes positioning.
First by the longitude and latitude of base station（L1,B1）Just calculated using Gauss the projection coordinate calculated under some coordinate system
（X1,Y1）.(X1, Y1)=GK (L1, B1) GK () represent Gaüss-Krüger projection
Then according to distance and bearing angle r, AOA, UE coordinate is calculated（X2, Y2)
X2 = X1+ r*cos(AOA)
Y2 = Y2+ r*sin(AOA)
UE longitude and latitude can be finally calculated using Gauss inverse（L2, B2）.
Analyzed more than, we realize the position positioning of sampled point, and then we are to the MR with positional information
Measurement data carries out GIS ground physics and chemistry grid, and grid precision is defined by the user as needed, rule of thumb most suitable to delete lattice precision
After determining grid precision for 400*400., then the corresponding index of statistics grid carries out grid face according to grid indication range
The filling of color, realizes the geographical rasterizing of LTE MR data.
