TGi=CGi/Call*T
Wherein, TGiThe service traffics of respective cell in i-th of grid are represented, i is the natural number less than or equal to n, and n represents to draw
The sum of the grid separated；CGiRepresent to be in the number of the MR sampled points of respective cell, C in i-th of gridallRepresent corresponding small
To sum up, T represents the service traffics of respective cell to the MR sampled points in area.
Further, it is also based on being in the number of the MR sampled points of any one cell in each grid, draws every
The packet loss of respective cell in individual grid.
Exemplarily, the number of the MR sampled points of any one cell is in each grid, it is right in each grid to draw
The packet loss of cell is answered, including：It is in number, each grid based on the MR sampled points that respective cell is in each grid
The descending of each MR sampled points of respective cell is in the up packet loss of each MR sampled points of respective cell, each grid
Packet loss, draw the packet loss of respective cell in each grid.
Here, the up packet loss of each MR sampled points be used for indicate UE to corresponding base station upload data when packet loss,
The descending packet loss of each MR sampled points is used to indicate corresponding base station to packet loss during UE transmission data；When actually implementing,
The up packet loss of MR sampled points and descending packet loss can be obtained from MR data.
In one implementation, the packet loss of respective cell in i-th of grid can be drawn according to below equation：
Wherein, PGiThe packet loss of respective cell in i-th of grid is represented, i is the natural number less than or equal to n, and n represents division
The sum of the grid gone out；ULQciX (s) represents to be in the up packet loss of s-th of MR sampled point of respective cell in i-th of grid
Rate, s are less than or equal to CGiNatural number, CGiRepresent to be in the number of the MR sampled points of respective cell in i-th of grid；
DLQciX (s) represents to be in the descending packet loss of s-th of MR sampled point of respective cell in i-th of grid.
It is understood that for same cell, the quantity and packet loss of the MR sampled points in each grid generation respectively

It is more, illustrate that the service traffics of the grid respective cell are bigger, conversely, illustrating that the service traffics of the grid respective cell are smaller；
The packet loss of respective cell is bigger in each grid, illustrates that the quality of service of the grid respective cell is poorer, conversely, illustrating the grid
The quality of service of lattice respective cell is better.
Obviously, if the service traffics of respective cell are bigger in a grid, the packet loss of respective cell is bigger, then illustrates
The grid belongs in Zone flow set and user perceives poor grid, and the grid belongs to the area for needing to carry out emphasis covering
Domain.
Step 204：Based on the service traffics drawn, the position at the covering center of respective cell is determined.
Exemplarily, following three kinds of modes can be used to determine the position at the covering center of respective cell.
The first implementation
The service traffics of respective cell in each grid can be utilized, the position coordinates of the central point of each grid is carried out
Weighted average calculation, draw the position coordinates at the covering center of respective cell.
Second of implementation

Degree；Using perceptibility of the respective cell in each grid, the position coordinates of the central point of each grid is weighted averagely
Calculate, draw the position coordinates at the covering center of respective cell.
Here, in perceptibility of the respective cell in each grid and each grid respective cell service traffics into
Positive correlation；For example, the service traffics of respective cell are into positive in perceptibility and i-th of grid of the cell in the i-th grid
Close；Preferably, perceptibility of the cell in the i-th grid is directly proportional to the service traffics of respective cell in i-th of grid.
The third implementation
The packet loss of respective cell in service traffics that can be based on respective cell in each grid and each grid,
Perceptibility of the respective cell in each grid is determined, using perceptibility of the respective cell in each grid, to each grid
The position coordinates of central point be weighted average computation, draw the position coordinates at the covering center of respective cell.
The service traffics of respective cell are into positive in perceptibility of the respective cell in each grid and each grid
Close, and with the packet loss of respective cell in each grid into positive correlation；For example, can be by the business of respective cell in each grid
Flow is multiplied with the packet loss of respective cell, draws perceptibility of the respective cell in each grid.
Step 205：The position at covering center and the position of corresponding base station based on each cell, it is determined that each cell pair
The azimuth for the antenna for base station answered.
Exemplarily, the position at covering center and the position of corresponding base station based on each cell, by each cell pair
The direction at the base station answered to covering center is defined as：The main beam direction of antenna for base station corresponding to each cell；Based on each small
The main beam direction of antenna for base station corresponding to area, it is determined that the azimuth of antenna for base station corresponding to each cell.
For example, the direction at the covering center of base station corresponding to A cells to A cells can be defined as：Base corresponding to A cells
The main beam direction of station antenna；Based on the main beam direction of antenna for base station corresponding to A cells, base station day corresponding to A cells is determined
The azimuth of line.

Determination antenna for base station azimuthal method, specifically, be primarily based on the Timing Advance and antenna angle of arrival of MR data,
MR sampled points are positioned, and according to the positional information of MR sampled points, determine the map grid at MR sampled points；With every
Zone uninterrupted of the quantity for the MR sampled points that individual grid includes as right assessment grid, with corresponding in each grid
The average packet loss ratio of cell assesses the quality of service of respective cell in grid, and according to the Zone flow that is evaluated and small
Area's quality of service, the position coordinates of the central point of each grid is weighted averagely, obtains the covering center of each cell
Position, finally, the azimuth parameter value of the antenna for base station of respective cell is determined according to the position at the covering center of each cell.
Compared with prior art, the embodiment of the present invention has the following advantages that：
1) parameter value precision in azimuth is higher；Precision of the embodiment of the present invention independent of map and propagation model, and
Based on measured data, the orientation angular dimensions of output more conforms to higher in network actual conditions, parameter setting precision.
2) efficiency of the network coverage is more preferable；With being based on flow physics and chemistry distribution of the embodiment of the present invention, it is contemplated that cell is actual to be needed
