Specific embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached
Figure and specific embodiment are described in detail.
The present invention crosses the low problem of covering analyzing method measurement result accuracy for existing, there is provided Yi Zhong little
Covering analyzing method is crossed in area, by the analysis of drive test data, analyzes the website distribution situation in cell periphery region,
Judge the reasonability of MPS process, so that it is determined that cell whether there is covering, it is simple and easy to apply, efficient, straight
See, improve accuracy.
As shown in figure 1, a kind of cell of the embodiment of the present invention crosses the analysis method of covering, including：
Step 101, obtains drive test terminal and is surveyed in all sample points when using cell to be measured as Serving cell
Measure the drive test data for obtaining.
Drive test terminal is a kind of according to the setting of staff operation, realizes the electronic equipment of drive test.Due to carrying
It is preceding that the expected measurement amount for obtaining is set, can just utilize the measurement amount data of drive test terminal to enter afterwards
The corresponding treatment of row.In the embodiment, analyzed using the drive test data of drive test terminal and whether judge a cell
Covered in the presence of crossing, drive test data at least includes drive test terminal using Serving cell, the non-clothes on periphery at point
Business cell and with the data such as the distance of cell.Therefore, first obtain drive test terminal using cell to be measured as
The drive test data that all sample point measurements are obtained during Serving cell.
Step 102, according to the drive test data of each sample point, determines that each sampled point is to be measured small with described
The distance between corresponding base station in area, and count with the sampled point as the center of circle, the distance is the model of radius
Interior number of cells is enclosed, the number of cells is crossed into cover index as the sampled point.
Step 103, cover index is crossed according to all sampled points, judges whether the cell to be measured deposits
Covered crossing.
By above-mentioned steps, the cell of the embodiment of the present invention crosses the analysis method of covering, according to drive test data,
By counting with sampled point as the center of circle, the distance between sampled point base station corresponding with cell to be measured is radius
In the range of number of cells, and the number of cells whether there is judging cell to be measured as cover index is crossed
Covering is crossed, the website distribution situation analysis to cell periphery region to be measured is realized, carries out judging the cell to be measured
The reasonability of covering, so that it is determined that it whether there is covering.The method of the embodiment of the present invention is simple and easy to apply,
In hgher efficiency, more accurate and visual understanding cell to be measured whether there is covering, and in the absence of existing method institute
The confinement problems of presence.
It is using cell to be measured as Serving cell in diagram sample point drive test terminal as a example by as shown in Figure 2
, first have to obtain the drive test data in the sample point, learnt near the sampled point also according to drive test data
There are non-service cell 1, non-service cell 2 and a non-service cell 3, and the sampled point is to cell to be measured
The distance of corresponding base station is d1, and the distance to the corresponding base station in non-service cell 1 is d2, to non-serving
The distance of the corresponding base station of cell 2 is d3, and the distance to the corresponding base station in non-service cell 3 is d4.And
With sampled point as the center of circle, d1 for radius scope as shown in phantom in FIG., it may be determined that including cell to be measured,
3 cells are had in the scope, the cover index of crossing of the sampled point is 3.Certainly, the embodiment of the present invention
In method, drive test terminal can be sampled in many places, and drive test terminal is more than one, with above-mentioned same
The mode of sample completes the cover index excessively of all sampled points during using cell to be measured as Serving cell, realizes treating
Survey cell whether there is covering and be judged.
In the above, statistics be with sampled point as the center of circle, sampled point base station corresponding with cell to be measured it
Between distance be the number of cells in the range of radius, the number of cells that will be determined is covered as crossing for sampled point
Index, because scope of statistics is to include cell minimum zone to be measured, reduces unnecessary expense.
But, resource consumption is not being considered, it is necessary on the premise of the better performances of drive test terminal, can set
With sampled point as the center of circle, a predeterminable range (more than the distance between sampled point base station corresponding with cell to be measured)
It is the number of cells in the range of radius, certainly, now also cannot again using number of cells as sampled point
Cover index is crossed, but the corresponding base station of all cells in the range of this is entered according to the distance with sampled point
Row sequence, the ranking value of cell to be measured crosses cover index as the sampled point.As in the range of a sampled point
Total n base station, each base station and sampled point distance respectively Lm (m=0,1,2 ... ... n), its
In cell distance to be measured be Ls.It is ranked up from small to large according to distance, the minimum ranking base stations value of distance
It is 1；The small ranking base stations value of distance time is 2 ... so, obtains being ordered as cell respective base station to be measured
Value Q, the cover index of crossing of the sampled point is exactly Q.
In addition, with sampled point as the center of circle, the distance between sampled point base station corresponding with cell to be measured is half
In the range of footpath, the corresponding base station of all cells in the range of this is ranked up according to the distance with sampled point,
The ranking value of cell to be measured is also feasible as the method for crossing cover index of the sampled point.But due to this
Scope is the sequence of cell to be measured as radius with the distance between sampled point base station corresponding with cell to be measured
Value must be maximum, be exactly the number of cells in the range of this, reduce sequence step, improve the effect of analysis
Rate.
Wherein, the quantity of sampled point must reach predetermined number, just can guarantee that cell sampled point sample to be measured
Restructuring.
After obtaining the cover index excessively of all sampled points, specifically, as shown in figure 3, step 103 includes：
Step 301, calculates the average value for crossing cover index of all sampled points, obtains described to be measured small
Cover index is crossed in area.
Because drive test terminal can be sampled in many places, and drive test terminal is more than one, for obtaining
The cover index excessively of the multiple sampled points for arriving, in order to embody the overall performance of cell to be measured, calculates all samplings
The average value for crossing cover index of point, cover index is crossed as cell to be measured.
Step 302, cover index is crossed according to the cell to be measured, judges that the cell to be measured whether there is
Cross covering.
It is understood that, although step 301 and step 302 pass through the mistake cover index of each sampled point
What average value carried out overall reflection cell to be measured crosses cover index, is a kind of preferably mode, but except this it
Outward, obtained according to predetermined weight to be measured apart from cell far and near distance to be measured also dependent on each sampled point
The cover index excessively of cell, certainly, also other implementation methods will not enumerate herein.
More specifically, step 302, including：
Step 3021a, the cover index of crossing of the cell to be measured is compared with first threshold, described to be measured
When crossing cover index more than or equal to the first threshold of cell, determines that the cell to be measured had covering.
First threshold is a threshold value of the staff according to determination in experiment or actual judgement, has such as served as covering and has referred to
When number is 6, there is covering, then determine 6 for first threshold.The mistake of the cell to be measured that will be obtained
Cover index compares with it, and when crossing cover index more than or equal to 6, cell to be measured is determined in cell to be measured
Covered in the presence of crossing.
Or step 302, including：
Step 3021b, obtains the signal and interference plus noise of all sampled point correspondences cell to be measured
Compare SINR value；
Step 3022b, the cover index of crossing of the cell to be measured is compared with first threshold, the SINR
Compare with Second Threshold, the first threshold is more than or equal in the cover index of crossing of the cell to be measured, and
When the SINR value is more than or equal to Second Threshold, determine that the cell to be measured had covering.
Step 3021b and step 3022b, when crossing Covering judgment, had been not limited to cell to be measured
Cover index, also further contemplates the SINR value in communication, and both are associated into analysis to judge
Covering whether there is.
However, it should be understood that, the covering analyzing of crossing of antenna is judgement on the whole, but in antenna not
During in the presence of crossing covering, the main lobe or secondary lobe of antenna but there may exist covering.Therefore, to analyze antenna
Main lobe whether there is covering, it is also possible to be analyzed using the above method, but, all samplings
Point is distributed in the main lobe coverage of the antenna of cell to be measured.
Main lobe coverage direction deviation angular region is typically used【- 60 °, 60 °】, the above method crosses in main lobe and covers
The application of analysis is covered as shown in figure 4, S401,【- 60 °, 60 °】In the range of the coverage direction angle of deviation
Obtain the drive test that drive test terminal is obtained when using cell to be measured as Serving cell in the measurement of all sample points
Data.S402, judges whether sampling number meets predetermined number, if sampling number is unsatisfactory for predetermined number,
Then it is considered other failures, did not continued to covering analyzing.If sampling number meets predetermined number, perform
S403.S403, according to the drive test data of each sample point, determines each sampled point with cell pair to be measured
The distance between base station answered, and count with sampled point as the center of circle, distance is the cell number in the range of radius
Amount, cover index is crossed using number of cells as sampled point.S404, the covering of crossing for calculating all sampled points refers to
Several average value, obtain cell to be measured crosses cover index.S405, by cell to be measured cross cover index with
First threshold compares, in the cell to be measured when crossing cover index more than or equal to the first threshold, really
There is covering in the fixed cell to be measured.Cover index and SINR association analysis, such as S406 can also will be crossed,
The Signal to Interference plus Noise Ratio SINR value of all sampled point correspondences cell to be measured is obtained, by cell to be measured
Cross cover index to compare with first threshold, SINR compares with Second Threshold, refer in the covering of crossing of cell to be measured
When number is more than or equal to the first threshold, and SINR value more than or equal to Second Threshold, determine to be measured small
There is covering in area.
Whether there is covering for the secondary lobe of antenna to be analyzed, likewise, similar to main lobe, it is also possible to make
It is analyzed in aforementioned manners, but, the secondary lobe of antenna of all sampling point distributions in cell to be measured covers
Lid scope.
Secondary lobe coverage direction deviation angular region typically using ±【60 °, 150 °】, the above method is in secondary lobe mistake
The application of covering analyzing as shown in figure 5, S501, ±【60 °, 150 °】Coverage direction angle of deviation model
Enclose what interior acquisition drive test terminal was obtained when using cell to be measured as Serving cell in the measurement of all sample points
Drive test data.S502, judges whether sampling number meets predetermined number, if sampling number is unsatisfactory for present count
Amount, then it is assumed that be other failures, do not continued to covering analyzing.If sampling number meets predetermined number, hold
Row S503.S503, according to the drive test data of each sample point, determines each sampled point with cell to be measured
The distance between corresponding base station, and count with sampled point as the center of circle, distance is the cell in the range of radius
Quantity, cover index is crossed using number of cells as sampled point.S504, calculates crossing for all sampled points and covers
The average value of index, obtain cell to be measured crosses cover index.S505, cover index is crossed by cell to be measured
Compare with first threshold, in the cell to be measured when crossing cover index more than or equal to the first threshold,
Determine that the cell to be measured had covering.Cover index and SINR association analysis can also will be crossed, such as
S506, obtains the Signal to Interference plus Noise Ratio SINR value of all sampled point correspondences cell to be measured, will be to be measured
The cover index of crossing of cell compares with first threshold, and SINR compares with Second Threshold, in the mistake of cell to be measured
When cover index is more than or equal to the first threshold, and SINR value more than or equal to Second Threshold, it is determined that
There is covering in cell to be measured.
In addition it is also necessary to explanation, the cell of the embodiment of the present invention crosses the analysis method of covering, is right
The covering analyzing method excessively of LTE cells, the cell to be measured is LTE cells.
In sum, the cell of the embodiment of the present invention cross the analysis method of covering being capable of adopting by drive test data
