The prior art lacks a clear and effective detection method for coverage limited situations.
The cell coverage limited situation refers to: the coverage of the cell is limited due to the blockage of the wireless environment by the base station antenna of the cell, the effective coverage of the cell is far lower than the design expectation, and the traffic of the cell is far lower than the surrounding average level. The reasons why the base station antenna of the cell is blocked by the radio environment include: in the case of a new station scenario, it is usually associated with base station selection and antenna installation location; in other scenarios, it is often associated with ambient wireless environment changes.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention.
It should be noted that, in this document, relational terms such as "first" and "second", and the like are used only to distinguish the same names, and do not imply a relationship or order between the names.
As shown in fig. 1, the present embodiment discloses a method for detecting limited cell coverage, which may include the following steps 101 to 103:
101. positioning a Measurement Report (MR) reported by User Equipment (UE) in a target cell to obtain positioning information of each MR.
In this embodiment, the target cell is a cell to be subjected to cell coverage limited detection. The positioning of the MR in step 101 may be longitude and latitude positioning of the MR, and the obtained MR positioning data is the longitude and latitude where the UE reports the MR. The implementation effect of the scheme is better when the MR positioning precision is higher, and meanwhile, the longer the MR data acquisition time is, the more complete the cell MR information is, and the higher the reliability is. In the embodiment, the positioning accuracy is below 100 meters, and the MR data acquisition time is 7 × 24 hours.
102. And determining a first number of MRs and a first average Reference Signal Received Power (RSRP) corresponding to each region in different azimuth angle ranges based on the positioning information of each MR, a plurality of regions pre-divided by the target cell and different preset azimuth angles of the standard position of the target cell.
In this embodiment, the correspondence between the direction angles and the regions is one-to-many, that is, one direction angle corresponds to a plurality of regions, that is, a plurality of regions exist in one direction angle range.
In this embodiment, the standard position of the target cell is, for example, an antenna installation position of a base station of the target cell, and the preset different azimuth angles are obtained by dividing, for example, 5 ° to 45 °, and the division interval is 5 °.
In this embodiment, the target cell is divided into areas in advance, that is, the coverage area of the target cell is rasterized. The size of the area can be determined according to the average station distance from each cell base station adjacent to the target cell base station and the MR positioning accuracy, and the embodiment adopts an area of 50 meters x50 meters. The latitude and longitude information of the area center can also be determined, and the latitude and longitude information of the area center can also be called as the absolute position information of the area.
In this embodiment, since the MR is located in step 101, the number of MRs and the average RSRP corresponding to each region in the target cell may also be determined.
In this embodiment, step 102 specifically includes the following steps 1021 to 1023 which are not shown in fig. 1:
1021. determining a region to which each MR belongs based on the positioning information of each MR and a plurality of regions divided by the target cell in advance;
1022. scanning the plurality of regions based on different preset azimuth angles of the standard position of the target cell, and determining a first number of MRs corresponding to each region in different azimuth angle ranges;
1023. and determining the first average RSRP of each region in different azimuth angle ranges based on each MR corresponding to each region in different azimuth angle ranges.
103. And determining a target azimuth angle and a target area corresponding to the limited coverage of the target cell based on the first number of MRs and the first average RSRP corresponding to each area in the different azimuth angle ranges and the relative distance between each area in the different azimuth angle ranges and the standard position of the target cell.
In this embodiment, based on the longitude and latitude information of the center of the area and the longitude and latitude information of the antenna installation position of the target cell base station, the relative distance between each area in the different azimuth angle ranges and the standard position of the target cell is determined.
As can be seen, the method for determining limited cell coverage disclosed in this embodiment determines the azimuth and the area corresponding to limited cell coverage by performing area division on the cell coverage and locating the acquired MR data to the area based on the number of MRs, the average RSRP, and the relative distance corresponding to each area in different azimuth ranges, so as to provide reliable reference and basis for an operator to take measures in time to solve the problems of reduced coverage level, reduced service quality, low efficiency, and the like caused by limited cell coverage, thereby providing possibility for maximizing base station investment benefits and minimizing radio environment blocking impact, and effectively determining the limited cell coverage without manual field processing.
In a specific example, the step 103 of determining a target azimuth and a target region corresponding to the limited coverage of the target cell based on the first number of MRs and the first average RSRP corresponding to each region in the different azimuth ranges and the relative distance between each region in the different azimuth ranges and the standard position of the target cell specifically includes the following steps 1031 to 1033 not shown in fig. 1:
1031. and determining an MR quantity difference value and an average RSRP difference value based on the first MR quantity and the first average RSRP corresponding to each region in the different azimuth angle ranges, and the second MR quantity and the second average RSRP corresponding to each region in the predetermined azimuth angle ranges when different azimuth angles are limited.
1032. And determining a distance difference value based on the relative distance of each area in the different azimuth angle ranges relative to the standard position of the target cell and the predetermined limited distance in the different azimuth angle ranges relative to the standard position of the target cell.
1033. And determining a target azimuth angle and a target area corresponding to the limited coverage of the target cell based on the MR number difference, the average RSRP difference and the distance difference.
Therefore, the method and the device for detecting the coverage limitation of the target cell jointly judge the situation of the coverage limitation of the target cell based on the two aspects of the azimuth limitation and the distance limitation, and improve the accuracy of detecting the coverage limitation of the cell.
In a specific example, the step 1032 determines the distance difference value based on the relative distance between each area in the different azimuth angle ranges and the standard position of the target cell, and the predetermined limited distance in the different azimuth angle ranges and the standard position of the target cell, specifically includes the following steps a and B:
A. and determining the maximum relative distance corresponding to different azimuth angles based on the relative distance of each area in the range of different azimuth angles relative to the standard position of the target cell.
In this embodiment, the maximum relative distances corresponding to different azimuth angles are the first maximum distances among the relative distances of the areas within the range of different azimuth angles with respect to the standard position of the target cell. Step a is to determine the area farthest from the standard position of the target cell in different azimuth angle ranges.
B. And determining a distance difference value based on the maximum relative distance corresponding to the different azimuth angles and the limited distance corresponding to the standard position of the target cell in the range of the different azimuth angles, wherein the distance difference value is | maximum relative distance-limited distance |.
In this embodiment, the limited distance in the different azimuth angle ranges relative to the standard position of the target cell is a second maximum distance in the relative distances between the areas in the different azimuth angle ranges and the standard position of the target cell when the predetermined cell coverage is limited.
In a specific example, the step 1033 of determining a target azimuth and a target area corresponding to the target cell coverage limitation based on the MR number difference, the average RSRP difference, and the distance difference specifically includes the following steps C to E:
C. and determining each first region of which the MR quantity difference value is less than or equal to the MR quantity difference value threshold and the average RSRP difference value is less than or equal to the average RSRP difference value threshold in different azimuth angle ranges based on the predetermined MR quantity difference value threshold and the average RSRP difference value threshold corresponding to each region in the azimuth angle range when different azimuth angles are limited.
D. And determining each second area with the distance difference value smaller than or equal to the distance difference value threshold in different azimuth angle ranges based on the predetermined distance difference value threshold when the distance corresponding to the different azimuth angle ranges is limited.
E. And determining the same area in each first area and each second area as the target area, and determining the azimuth corresponding to the target area as the target azimuth.
As can be seen, the method for determining limited cell coverage disclosed in this embodiment performs region division on the cell coverage, locates the acquired MR data to a region, and then determines the limited coverage of the target cell based on the number of MRs, the average RSRP, and the relative distance corresponding to each region in different azimuth ranges, based on the two aspects of "limited azimuth" and "limited distance", so as to improve the accuracy of detecting limited cell coverage, provide reliable reference and basis for operators to take measures in time to solve the problems of reduced coverage, reduced service quality, low efficiency, and the like caused by limited cell coverage, provide possibility for maximizing base station investment benefits, minimizing radio environment blocking influences, and effectively determine the limited cell coverage without manual field processing.
