S101: aggregating according to the position information of a plurality of UE in a cell to obtain the antenna main lobe direction of the cell;
s102: and determining that the cell has antenna reverse connection or working parameter errors according to the main lobe direction of the antenna.
Specifically, determining that the cell has an antenna reverse connection or an industrial parameter error according to the antenna main lobe direction includes:
monitoring a number of times the plurality of UEs are handed over from the cell to a neighboring cell while the plurality of UEs are indoors;
and determining that the cell has antenna reverse connection or working parameter errors according to the antenna main lobe direction and the times of switching from the cell to the adjacent cell.
Optionally, determining that there is an antenna reverse connection or an employee id error in the cell according to the antenna main lobe direction includes:

detecting location information of a plurality of UEs in the cell by assisted global positioning AGPS;
and aggregating according to the position information of the plurality of UEs to obtain the antenna main lobe direction of the cell.
Optionally, the received signal strength of the plurality of UEs exceeds-100 db.
Fig. 2 is a flowchart of a method for detecting antenna and antenna parameters according to an embodiment of the present invention. The method comprises the following specific steps:
s201, starting AGPS measurement of basic UE;
s202, starting measurement judgment of the UE and judgment of a switching relation between the UE and an adjacent cell;
s203, detecting the judgment of the switching relation between the main lobe direction of the antenna and the azimuth angle of the working parameter and the adjacent cell;
s204, determining the specific type of the antenna and the work parameter error;
specifically, it is checked whether the cell has a problem according to the AGPS measurement of the UE.
The method mainly comprises the step of obtaining the center position of a cell by aggregating the position information of the UE of which the signal intensity of a received cell signal exceeds a certain threshold so as to judge whether the cell has a problem. The threshold of the cell UE is defaulted to-100 dBm.
The method specifically comprises the following steps: the method comprises the steps of obtaining the center position of a cell through aggregation according to the position information of UE (user equipment) with the signal strength of a received cell signal exceeding a certain threshold, taking the cell site as a starting point and a direction angle from the center position as an actual azimuth angle of the cell, and generally setting the actual azimuth angle and an azimuth angle error on engineering parameters to be 90 degrees if the actual azimuth angle and the azimuth angle error on the engineering parameters exceed a certain threshold. Then the cell may have problems of reverse antenna connection or working parameter errors, which refer to errors in azimuth or errors in longitude and latitude.
Wherein, the UE received signal strength may be: RSSI for GSM systems, RSCP (or CPICH Ec/No) for UMTS systems, and RSRP (or RSRQ) for LTE systems. The location information, i.e. latitude and longitude information, is obtained by AGPS measurement. The central position of the cell is obtained by aggregating the position information of the UE whose received signal strength exceeds a certain threshold in the cell, and the aggregation method may be, but is not limited to: and respectively averaging the longitude and latitude of all the UE meeting the conditions.
The actual azimuth angle is the direction of the center position obtained by aggregating the cell base station position pointing measurement results, and the cell base station position is obtained according to engineering parameters.
Specifically, whether the cell has a problem is checked according to the switching data between the cell and the adjacent cell.
Whether a cell has a problem is mainly identified according to the fact that a large number of handovers occur between a neighboring cell which should not have a large number of handovers and the cell.
The method specifically comprises the following steps: the switching frequency of a neighboring cell and the cell exceeds a certain threshold, the switching frequency is determined to be 200 by default, and the proportion of the total switching frequency of the cell exceeds the certain threshold, the switching frequency is determined to be 5 by default, if the distance between the neighboring cell and the cell exceeds the certain threshold, and the azimuth angles of the cells deviate from each other by a certain angle, the cell is determined to have the problems of reverse antenna connection or working parameter error, and the working parameter error indicates the azimuth angle error or the longitude and latitude error.
The deviation of the cell azimuth angles from each other by more than a certain angle means that both the angle of the serving cell deviating from the neighboring cell and the angle of the neighboring cell deviating from the serving cell are greater than a certain threshold and are defaulted to 150 degrees, wherein:
the angle of the serving cell deviating from the adjacent cell is the included angle between the azimuth angle of the serving cell and the connection line between the cell pairs;
the angle of the adjacent cell deviating from the service cell is the included angle between the azimuth of the adjacent cell and the connecting line between the cell pairs.
And the positions of the cell and the adjacent cell are obtained according to the engineering parameters.
And traversing the cell pair formed by the cell and all the adjacent cells of the cell, and respectively checking whether the cell has a problem according to the switching data.
Specifically, the probability coefficient of cell problems is determined by integrating the times of cell problems detected in steps 1 and 2.
Where the cell is detected based on the measurement scheme and detected based on handover may have different probability coefficients, for example, the probability coefficient increment detected based on measurement is deltaprobabilitylmr, and the probability coefficient increment detected based on the handover statistics scheme is deltaprobabilitylho. The method for calculating the probability coefficient of the cell problem includes, but is not limited to, the following methods:
scheme 1: based on the switching statistics, if a problem exists between the cell and one of the adjacent cells, the probability coefficient of the cell having the problem is added with an increment, namely the probability coefficient of the cell having the problem is as follows:
DeltaProbabilityMR*i+DeltaProbabilityHO*j
wherein the content of the first and second substances,
i:0 or 1, i =1 when the cell is checked for problems based on the measurement results, and 0 otherwise.
j, when checking the local cell, checking the number of the cell pairs with problems. That is, the cell is used as a serving cell, and it is checked that the condition that the problem is detected based on the handover between j neighboring cells and the serving cell is satisfied.
Scheme 2: deltaProbabilityHO represents the maximum probability coefficient increment that can be generated by all the adjacent cells meeting and deviating the angle and distance conditions, namely the probability coefficient of the cell with problems is as follows:
DeltaProbabilityMR*i+DeltaProbabilityHO*(j/K)
wherein the content of the first and second substances,
i:0 or 1, i =1 when the cell is checked for problems based on the measurement results, and 0 otherwise.
j, when checking the cell, checking the number of the cell pairs with problems. That is, the cell is used as a serving cell, and it is checked that the condition that the problem is detected based on the handover between j neighboring cells and the serving cell is satisfied.
And K, representing the number of the adjacent cells meeting the deviation relation and the distance relation between the adjacent cells and the cell in all the adjacent cells of the cell as described in Step 2.
Optionally, the cells checked in Step 1-2 are further screened based on the "probability coefficient of cell problem". The screening method can be as follows: a "cell problematic probability coefficient" is a truly problematic cell if it is greater than a threshold.
Optionally, the problem type of the cell is determined according to information such as the number of problematic cells in one site and AGPS measurement results:
(1) If two cells in a site have problems and the aggregation centers of the UEs reported by the two cells and measured by AGPS are respectively in the directions of the azimuth angles (main lobes of the cell antennas in the plan) of each other (the allowable deviation is within a certain threshold), the site is considered to have the problem of antenna reverse connection.
(2) When a site has at least three cells with different azimuth angles, each cell obtains the central position of each cell according to AGPS measurement reported by UE, and then the actual position of the site is obtained through aggregation based on the central positions of a plurality of cells, wherein the aggregation method comprises but is not limited to averaging the longitude and the latitude respectively. And if the distance between the obtained actual position of the station and the position of the worker parameter obtained based on the longitude and latitude of the worker parameter is larger and the default is 500M, the longitude and latitude of the worker parameter is considered to have a problem.
