All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of a method for determining a problem source cell that causes overlapping coverage according to an embodiment of the present invention, as shown in fig. 1, the method for determining a problem source cell that causes overlapping coverage includes: s11, determining a plurality of effective sampling points, wherein for any effective sampling point in the plurality of effective sampling points, the signal intensity of a serving cell at any effective sampling point is greater than-110 dBm, and the difference value between the signal intensity of a target cell at any effective sampling point and the signal intensity of the serving cell at any effective sampling point is greater than-6 dB; s12, acquiring the position of each effective sampling point, dividing the coverage area of the target cell, and determining the coverage area of each effective sampling point according to the position of each effective sampling point, wherein the coverage area comprises a back coverage area, an over-wide coverage area, an over-far coverage area and a reasonable coverage area; s13, determining whether the target cell is a problem source cell causing overlapping coverage according to the proportion of the number of the effective sampling points in each type of coverage area to the total number of all the effective sampling points.
Specifically, in mobile communications, after the cells are established, a reasonable coverage area is allocated to each cell, but the actual coverage area of the cells usually exceeds the allocated reasonable coverage area, so that signal interference is caused between the cells to cause overlapping coverage, compared with the area which is not covered by the overlapping coverage, the throughput loss of the area covered by the overlapping coverage is up to more than 70%, and the performance loss caused by the same-frequency interference is further increased with the deepening of the overlapping coverage degree.
The overlapping coverage area is characterized in that the signal strength of the serving cell in the overlapping coverage area is greater than-110 dBm, the difference between the signal strength of the adjacent cell in the overlapping coverage area and the signal strength of the serving cell in the overlapping coverage area is greater than-6 dB, by the above characteristics, the embodiment firstly determines a plurality of effective sampling points, any one of the plurality of effective sampling points is enabled to be greater than-110 dBm, the signal strength of the target cell at any one effective sampling point and the difference between the signal strength of the target cell at any one effective sampling point and the signal strength of the serving cell at any one effective sampling point are greater than-6 dB, so that the situation that any one effective sampling point is in the overlapping coverage area of the target cell or in the allocated reasonable coverage area can be ensured, and then whether the target cell is a problem source cell causing overlapping coverage can be judged based on the position distribution situation of the effective sampling points in the whole coverage area.
For the coverage area of the target cell, the coverage area can be divided into a back coverage area, an over-wide coverage area, an over-far coverage area and a reasonable coverage area, the number of effective sampling points in each type of coverage area is counted according to the position of each sampling point, and whether the target cell is a problem source cell causing overlapping coverage can be determined according to the proportion of the number of the effective sampling points in each type of coverage area to the total number of all the effective sampling points.

Specifically, as shown in fig. 2, the position of the base station of the target cell is taken as an origin, a ray passing through the origin and having an included angle with a ray at which the azimuth of the target cell is located is taken as an oversized coverage boundary, for example, the first preset angle may be 45 °; taking rays which pass through the origin and have an included angle with the rays of the azimuth angle of the target cell of a second preset angle as a back coverage boundary, wherein for example, the second preset angle is usually 90 degrees; the method comprises the steps of dividing an area between an excessively wide coverage boundary and a back coverage boundary into an excessively wide coverage area, dividing an area between the back coverage boundaries into back coverage areas, dividing an area which is located between the excessively wide coverage boundaries and is away from a base station of a target cell within a first distance value range into an excessively far coverage area, and dividing an area which is located between the excessively wide coverage boundaries and is located away from the base station of the target cell within the first distance value range into reasonable coverage areas. The area to which each effective sampling point belongs is determined according to the coordinates of each effective sampling point, as shown in fig. 2, the effective sampling points with positions falling into the back coverage area are called back coverage points, the effective sampling points with positions falling into the over-wide coverage area are called over-wide coverage points, the over-wide coverage points are further divided into points with under-lobe over-wide coverage and points with over-wide coverage of the upper lobe according to the azimuth of the target cell, the effective sampling points with positions falling into the over-far coverage area are called over-far coverage points, and the effective sampling points with positions falling into the reasonable coverage area are called reasonable coverage points.

7. A device for determining a problem source cell that causes overlapping coverage, comprising:
a first determining module, configured to determine a plurality of valid sampling points, where, for any valid sampling point of the plurality of valid sampling points, a signal strength of a serving cell at the any valid sampling point is greater than-110 dBm, and a difference between a signal strength of a target cell at the any valid sampling point and a signal strength of the serving cell at the any valid sampling point is greater than-6 dB;
the dividing module is used for obtaining the position of each effective sampling point, dividing the coverage area of the target cell, and determining the coverage area of each effective sampling point according to the position of each effective sampling point, wherein the coverage area comprises a back coverage area, an over-wide coverage area, an over-far coverage area and a reasonable coverage area;
the second determining module is used for determining whether the target cell is a problem source cell which causes overlapping coverage according to the proportion of the number of the effective sampling points in each type of coverage area to the total number of all the effective sampling points;
wherein, the division module is further used for:
taking the position of the base station of the target cell as an origin, taking a ray which passes through the origin and has an included angle of a first preset angle with a ray of the azimuth of the target cell as an oversized coverage boundary, and taking a ray which passes through the origin and has an included angle of a second preset angle with a ray of the azimuth of the target cell as a backward coverage boundary;
dividing the area between the over-wide coverage dividing line and the back coverage dividing line into an over-wide coverage area, dividing the area between the back coverage dividing line into back coverage areas, dividing the area between the over-wide coverage dividing line and away from the base station of the target cell within a first distance value range into over-far coverage areas, and dividing the area between the over-wide coverage dividing line and away from the base station of the target cell within the first distance value range into reasonable coverage areas.
8. An electronic device, comprising:
at least one processor, at least one memory, and a data bus; wherein:
the processor and the memory complete communication with each other through the data bus; the memory stores program instructions executable by the processor, the processor invoking the program instructions to perform the method of any of claims 1-6.
9. A non-transitory computer readable storage medium storing a computer program that causes the computer to perform the method of any one of claims 1 to 6.
