With reference to embodiment, the present invention is further described in more detail.
The method of tested rotating platform provided in an embodiment of the present invention, as shown in figure 1, methods described includes：
Step 101：Obtain the MR data of each terminal in designated area；
Specifically, the region for needing to carry out signal adjustment is specified first, here it is possible to which all-network overlay area is divided into
Some key areas can also rule of thumb be divided by the region of multiple signal adjustment manually by network optimization personnel；Can
To set a threshold value to performance parameters such as the SINR in signal adjustment region, if it find that performance parameter surpasses in current check
Go out threshold range, then start adjustment；It is determined that need carry out signal adjustment region after, obtain each terminal in the designated area
MR data；The MR data include：The cell number (Ecell_ID) of main plot, the cell number of adjacent cell (Ecell ID),
International mobile subscriber identity (IMSI：International Mobile Subscriber Identification

Step 802：Judge whether cell SINR is less than threshold values according to user terminal MR data；Performed if threshold values is less than
Step 803；Otherwise, it is determined whether needing to carry out forcing adjustment antenna, if desired, then this row step 803, otherwise, flow terminates；
Step 803：By reporting MR data to divide user's cluster, cell cluster, and calculate user's cluster central point；
Step 804：By work ginseng and user's cluster central point calculate in the cell cluster each cell to cluster center angle of declination and
Azimuth；
Step 805：Angle of declination and azimuth are issued into radio frequency unit adjustment antenna electronics inclination angle and electronic bearing angle；
Step 806：Each cell angle of declination in cell cluster is pushed in units of degree, and judges whether SINR rises,
Until SINR value is not rising, angle of declination corresponding to SINR value peak is taken to adjust antenna；
