Those skilled in the art can know that generally, antenna feeder device reverse connection includes the following two types: main diversity connection reverse and same-frequency same-site cell reverse connection. Referring to FIG. 4 , it is a schematic diagram of the main diversity connection reverse of the antenna feeder equipment, wherein the Rx of the cell A and the Rx of the cell B are wrongly connected, resulting in the main diversity connection reverse. Referring to Figure 5, it is a schematic diagram of the reverse connection of the antenna feeder device, in which the Tx/Rx of cell A and the Tx/Rx of cell B are connected incorrectly, and the Rx of cell A and the Rx of cell B are connected incorrectly, resulting in cell connection opposite.

In order to describe the method provided by the embodiment of the present invention in detail, this embodiment takes three co-frequency cells under the base station as an example: cell 1, cell 2, and cell 3. Correspondingly, the 2-3 cells are collected respectively The main and diversity RTWP values of cell 1, cell 2, and cell 3 within an hour.

102: Calculate the correlation coefficient between the main set RTWP value and the diversity RTWP value of each cell. See below for details:

Firstly, set the sampling interval, for example, take 1 second as a sampling point; secondly, calculate the correlation coefficient between the main set and the diversity two sets of data in each plot. For example, assuming that the set of sampling data points of the main set RTWP of cell 1 is an array A, and the set of sampling data points of the diversity RTWP of cell 1 is an array B, the specific algorithm can be as follows:

P=Cov(A,B)/σ _A *σ _B

in, $\mathrm{Cov}(A,B)=\frac{1}{N}\·\underset{i=1}{\overset{N}{\mathrm{\Σ}}}(x_i-\stackrel{\‾}{x})({\mathrm{the\; y}}_i-\stackrel{\‾}{\mathrm{the\; y}})$

Among them, x, y are the average number i∈(1, 2, ..., N) of array A and array B respectively

Therefore, the formula for calculating the correlation coefficient P is:

$\mathrm{<span\; class="notranslate">\; P</span>}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; N</span>}\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\overset{\mathrm{<span\; class="notranslate">\; N</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; x</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; -</span>\stackrel{<span\; class="notranslate">\; \&OverBar;</span>}{\mathrm{<span\; class="notranslate">\; x</span>}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; the\; y</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; -</span>\stackrel{<span\; class="notranslate">\; \&OverBar;</span>}{\mathrm{<span\; class="notranslate">\; the\; y</span>}}<span\; class="notranslate">\; )</span>}{\sqrt{\mathrm{<span\; class="notranslate">\; N</span>}\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\overset{\mathrm{<span\; class="notranslate">\; N</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; x</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; -</span>{<span\; class="notranslate">\; (</span>\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\overset{\mathrm{<span\; class="notranslate">\; N</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; x</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}\sqrt{\mathrm{<span\; class="notranslate">\; N</span>}\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\overset{\mathrm{<span\; class="notranslate">\; N</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; the\; y</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; -</span>{<span\; class="notranslate">\; (</span>\underset{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\overset{\mathrm{<span\; class="notranslate">\; N</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; the\; y</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}}$

Therefore, the correlation coefficient between the main set RTWP value and the diversity RTWP value of cell 1 is calculated by the above formula. Similarly, the correlation coefficient between the main set RTWP value and the diversity RTWP value of each cell of the base station can be calculated. The method is similar and will not be repeated here.

103: According to the correlation coefficient of the main set RTWP value and the diversity RTWP value calculated above, if the correlation coefficient is close to 0, it means that the connection of the antenna feeder equipment in this cell is reversed.

104: If the correlation coefficient between the main set RTWP value and the diversity RTWP value of a certain cell is smaller than a preset relative threshold, perform step 105.

Wherein, the preset relative threshold is obtained by setting by testers according to test requirements. In order to describe the method provided by the embodiment of the present invention in detail, this embodiment takes the preset relative threshold as 0.5 as an example, assuming that the correlation coefficient between the main set RTWP value and the diversity RTWP value of cell 1 is 0.3 for illustration.

105: Obtain a correlation coefficient between the main set RTWP value and the diversity set RTWP value of the same-frequency co-sited cell of the current cell.

Wherein, the current cell is the cell whose correlation coefficient between the main set RTWP value and the diversity RTWP value described in the above step 104 is less than the preset relative threshold. Assuming that the current cell is cell 1, the base station ID in the base station configuration , downlink frequency point information, etc., obtain the co-sited cell with the same frequency as the cell 1, and then obtain the correlation coefficient between the main set RTWP value and the diversity RTWP value of the co-sited cell with the same frequency with the cell 1, assuming that the The same-frequency co-sited cells of 1 are cell 2 and cell 3.

106: According to the correlation coefficient of the main set RTWP value and the diversity RTWP value of the co-sited cell of the current cell and the preset relative threshold, determine the cell that has the main diversity connection of the antenna feeder equipment in the current cell. See below for details:

1) If the correlation coefficients of the main set RTWP value and the diversity RTWP value of the co-sited cell with the same frequency as the current cell are not lower than the preset relative threshold, it means that the reverse connection of the antenna feeder equipment in the current cell is caused by other reasons, such as Antenna feeder equipment failure and other reasons, (such as the performance and parameters of the antenna cannot meet the requirements of use; the joint is tightly sealed, so that water vapor enters the feeder and affects signal transmission; the erection position is unreasonable, such as too close to the interference source, etc.; the power of the transmitter exceeds the antenna Rated power, the antenna is overloaded or burned; subject to foreign objects, typhoons, lightning, etc., the original structure and performance parameters of the antenna are changed, degraded, inaccurate; the cable head is not welded firmly, the signal is sometimes absent, etc.); the situation is not in the within the scope of this embodiment.

2) If there is only one cell with the same frequency as the current cell and the correlation coefficient between the main set RTWP value and the diversity RTWP value is lower than the preset relative threshold, it means that there is an antenna feeder device between this cell and the above current cell Reverse.

For example, assuming that in the same-frequency co-sited cell of cell 1, only the correlation coefficient between the main set RTWP value and the diversity RTWP value of cell 3 is lower than the preset relative threshold, while the correlation coefficient between the main set RTWP value and the diversity RTWP value of cell 2 is If the coefficient is not lower than the preset relative threshold, it means that cell 3 and cell 1 have main diversity reverse connection.

3) If there are at least two cells in the co-sited cell with the same frequency as the current cell, the correlation coefficients of the main set RTWP value and the diversity RTWP value are lower than the preset relative threshold, then calculate the main set RTWP value and the same value of the current cell respectively. If the correlation coefficient of the diversity RTWP value of the frequency co-site cell is close to 1, it means that the co-site co-site cell corresponding to the correlation coefficient close to 1 and the above-mentioned current cell have main diversity connection reverse.

For example, assuming that in the same-frequency co-sited cell of cell 1, the correlation coefficients of the main set RTWP value and diversity RTWP value of cell 2 and cell 3 are all lower than the preset relative threshold, then further, calculate the main set RTWP of cell 1 The correlation coefficient between the value and the diversity RTWP value of cell 2, and the correlation coefficient between the main set RTWP value of cell 1 and the diversity RTWP value of cell 3, assuming that the correlation coefficient between the main set RTWP value of cell 1 and the diversity RTWP value of cell 2 is calculated The coefficient is close to 1, that is, the correlation coefficient of the main set RTWP values of cell 1 and cell 2 is the maximum correlation coefficient, which means that cell 1 and cell 2 have main diversity connection reverse.

So far, through the above steps 101-106, according to the correlation coefficient of the main set RTWP value and the diversity RTWP value of the co-sited cell of the current cell and the preset relative threshold, it is determined that there is a main diversity connection reaction of the antenna feeder equipment with the current cell. district.

Referring to Figure 7, perform the following steps to confirm whether there is a cell connection reverse problem in the current cell, see the following for details:

201: Obtain optimization data and soft handover information of co-frequency neighbor cells of the current cell within the time period to be tested;

Among them, the above optimization data specifically includes: 1A event reporting times, 1A event reporting time, active set cell ID, RSCP (Received Signal Code Power, received signal code power) and Ec/No, detection set cell ID, RSCP and Ec /No etc.;

The above-mentioned soft handover information specifically includes: the number of soft handover events, the time of soft handover events, the ID of the active set cell, and the ID of the target cell;

Among them, those skilled in the art can know that the above-mentioned 1A event refers to a relative threshold increase event. In a WCDMA mobile communication network, it means that the quality of a cell is close to the best cell or the quality of the active set. UE (UserEquipment, user terminal) When the measurement finds that the primary common pilot channel of a cell in the detection set is better than the primary common pilot channel of a cell in the current active set, the UE reports a 1A event report through the measurement report; the above active set refers to the presence of soft handover with the UE The connected cell, the UE can be a mobile phone; the above detection set refers to the list of cells that the UE continuously measures, but the cell pilot Ec/Io value in the cell list is not large enough to join the active set; the above The target cell refers to a certain cell to which the UE moves from the active set cell, that is, the active set cell and the cell undergo soft handover, and this cell is the target cell; the above Ec/Io refers to the chip energy/interference power spectral density; Ec/No, refers to RSCP/RSSI (ReceivedSignal Strength Indication, received signal strength); the so-called soft handover refers to the change of the communication cell where the UE is located in the CELL-DCH state. In the WCDMA system, soft handover is performed between channels of the same frequency ;

202: Obtain the optimal cell according to the number of times the above 1A event is reported and the preset acquisition threshold;

Among them, assuming that during the test period, 6 1A event reports were obtained, as shown in Table 1,

Table 1

1A event reported community 1A 1, 2 1A 2, 3 1A 1, 3 1A 1, 3 1A 3, 2 1A 2, 1

Assuming that the preset acquisition threshold set by the tester is 2 times, count the number of reports reported by the cell that is the first reported cell during the test period, as shown in Table 2. For example, count the 1A events reported by the cell as the optimal cell The number of 1A events occurring in cell 1 as the optimal cell is 3 times, the number of 1A events occurring in cell 2 as the optimal cell is 2, and the number of 1A events occurring in cell 3 as the optimal cell is 1 time. According to the above The 1A event reporting threshold can obtain the two optimal cells exceeding this threshold, that is, cell 1 and cell 2, which are the cells that need to be analyzed in the next stage. In this embodiment, cell 1 is taken as the current cell to be analyzed as an example for description, see the following.

203: Obtain a forward neighbor cell set of the optimal cell according to the geographical location information of the optimal cell;

Among them, taking the analysis of the optimal cell 1 as an example, according to the geographical location information (such as latitude and longitude, azimuth, etc.) of the optimal cell 1, the forward neighbor cell set of the optimal cell 1 is obtained, see the cell provided in Figure 8 schematic diagram. The co-sited cells of cell 1 are cell 2 and cell 3 respectively, and cells 2, 3, 4, 5, 6, 7, and 8 are all the first-layer adjacent cells of cell 1 (the so-called first-layer adjacent cells refer to The longitude, latitude and azimuth of the small block are drawn on the map, and the cells with adjacent sides and vertices are the first layer of neighbors); then the forward neighbor set of cell 1 (the so-called forward neighbor set refers to The first layer of adjacent cells of a cell (excluding the same-frequency co-sited cells of this cell) is {the first-layer adjacent cell of cell 1 - the same-frequency co-sited cell of cell 1}={cells 4, 5, 6, 7, 8 }.

204: According to the number of soft handovers that occur between the optimal cell and each cell in the forward neighbor cell set, and the soft handover times that occur in each cell in the forward neighbor cell set between the optimal cell and its co-sited cell of the same frequency, determine the A cell with reversed cell connection appears in the optimal cell. details as follows:

First, count the number of soft handoffs between the optimal cell and each cell in the forward neighbor cell set, and the soft handover times between the optimal cell and the forward neighbor cell set of its own co-sited cell;

Secondly, according to the above statistics, if the number of soft handovers between the optimal cell and each cell in the forward neighbor cell set of a co-sited cell is greater than the soft handover times between the optimal cell and its own forward neighbor cell set, and is greater than the number of soft handover times of each cell in the forward neighbor cell set of the optimal cell and other co-sited cells at the same frequency, then the cell that is opposite to the optimal cell is determined.

For example, the optimal cell is cell 1, and the co-sited cells of the optimal cell 1 are respectively marked as cell 2 and cell 3; the number of soft handovers between cell 1 and each cell in its forward neighbor cell set is W1 times, for example, According to the collected soft handover information, it can be known that the ID of the active set cell is cell 1 and the ID of the target cell is cell 8, which means that a soft handover from cell 1 to cell 8 has occurred. Similarly, it can be known that the cell 1 The number of soft handovers with each cell in the forward neighbor cell set. In the same way, it can be known that the number of soft handovers that occur in each community of the forward adjacent cell set of cell 1 and cell 2 is W2 times; the number of soft handovers that occur in each cell of the forward adjacent cell set of cell 1 and cell 3 is W3 times;

If W2 is greater than W1, and W2 is greater than W3, it means that cell 2 and cell 1 are wrongly connected, and the cell connection is reversed.

So far, according to the correlation coefficient of the main diversity RTWP value in all the cells, obtain the cell where the antenna feeder equipment is reversed, and further, according to the correlation coefficient of the main diversity RTWP value of the cell and the preset relative threshold, determine the frequency of the antenna feeder device.
