The latitude and longitude information of any two points known in the state of the art can calculate at this distance between 2 points, it is assumed that A points
Longitude and latitude be (LonA, LatA), the longitude and latitude of B points is (LonB, LatB), according to the benchmark of 0 degree of warp, east longitude degree of learning from else's experience
On the occasion of, west longitude degree of learning from else's experience negative value, north latitude takes 90- latitude values, and south latitude takes 90+ latitude values, then A points be counted as (MLonA, MLatA),
B points are counted as (MLonB, MLatB), and 2 points of A, B distance Dist can be calculated by following equation (1) (2),
Dist=R*arccos (C) * Pi/180 (1)
C=sin (MLatA) * sin (MLatB) * cos (MLonA-MLonB)+cos (MLatA) * cos (MLatB) (2)

It is (3*Dist1+4*Dist2+5*Dist3+ that result of calculation according to step S502 and S503, which obtains Weighted distance d1,
6*Dist4)/(3+4+5+6)。
If Target cell level intensity be more than preset value on the premise of, with Cell1, Cell2 ... CellN represent with
Target cell has multiple main serving cells of corresponding relation, Num1, Num2 ... NumN represent each main serving cell respectively with
The corresponding number of Target cell, Dist1, Dist2 ... DistN represent that each main serving cell is corresponding with Target cell respectively
Physical distance, then general Weighted distance MRwightdist can be calculated by following equation (3) (4) (5):
{Cell1->Num1,Cell2->Num2,Cell3->Num3...CellN->NumN} (3)
{Cell1->Dist1,Cell2->Dist2,Cell3->Dist3...CellN->DistN} (4)
MRwightdist=(Num1*Dist1+Num2*Dist2+Num3*Dist3+...+NumN*DistN)/(Num1+
Num2+Num3+...+NumN) (5)
Step S505, radio transmission model is chosen, calculates Target cell theoretical coverage distance d；

Lpath=46.3+33.9logfc-13.82loght-a (hr)+(44.9-6.55loght) logd+Cx (6)
A (hr)=(1.11lgf-0.7) hr-1.56lgf+0.8 (7)
TX+G-Lpath-L=RXmin (8)
Wherein, fc is system centre frequency, and WCDMA networks value is 2000；
Ht is antenna height and height above sea level drop sum, and height above sea level drop refers to that the height above sea level of base station subtracts the sea of UE (mobile phone)
Degree of lifting；
Hr is UE height above sea levels, usual 1.65 meters of value；
D is the theoretical coverage distance of the Target cell calculated；

Table 1
Table 2
Step S506, d1 and the absolute value d3 of d differences are calculated；
The difference that the theoretical coverage distance d of Target cell obtains is subtracted with Weighted distance d1 to take absolute value to obtain d3, i.e. d3
Taken absolute value equal to (d1-d).
Step S507, judge whether d3 is more than predetermined threshold value, if going to step S508, otherwise go to step S509；
Step S508, determine that antenna-feedback system has descending failure；
It is described to detect the antenna-feedback system to be measured according to the theoretical coverage of the Weighted distance and Target cell distance
Descending failure include：The absolute value of the Weighted distance and the theoretical coverage distance difference of the Target cell is calculated, and is compared
The absolute value and predetermined threshold value；If judging, the absolute value is more than the predetermined threshold value, knows and described treats observation
Unreasonable antenna feeder installation site, antenna feeder engineering parameter improper, the antenna feeder hydraulic performance decline of setting or antenna model selection be present and do not conform in feedback system
The descending failure of reason.
When absolute value d3 is more than predetermined threshold value, illustrate Weighted distance d1 and Target cell theoretical coverage distance d phases
Difference is larger, and the theoretical coverage distance d or Weighted distance d1 that Weighted distance d1 may be much smaller than Target cell may be much larger than target
The theoretical coverage distance d of cell, specifically reflect that antenna-feedback system to be measured has that antenna feeder installation site is unreasonable, antenna feeder engineering parameter
Improper, antenna feeder hydraulic performance decline or the irrational descending failure of antenna model selection are set.
Step S509, determine that descending failure is not present in antenna-feedback system；
When absolute value d3 is not more than predetermined threshold value, illustrate that antenna-feedback system covering to be measured is normal, in the absence of descending failure.
Step S510, terminate.
Corresponding number of the embodiment of the present invention especially by each main serving cell with Target cell, and each main serving cell
Weighted distance is obtained with the physical distance of Target cell, according to the exhausted of the theoretical coverage distance difference of Weighted distance and Target cell
To value compared with predetermined threshold value, judge whether Weighted distance differs larger with the theoretical coverage distance of Target cell, if
Differ larger explanation antenna-feedback system and have that antenna feeder installation site is unreasonable, antenna feeder engineering parameter sets improper, antenna feeder hydraulic performance decline
Or the irrational descending failure of antenna model selection, if difference does not illustrate that antenna-feedback system covering to be measured is normal, in the absence of descending event more very much
Barrier, the analysis to antenna-feedback system down direction problem is implemented and has judged.
