However, the number of sampling points which can be obtained by the way of the road test or the fixed point test is small, and the distribution range of the sampling points is small, namely, the evaluation result obtained by the way of the road test or the fixed point test has certain one-sidedness; meanwhile, a large amount of manpower and material resources are needed in a drive test or fixed point test mode, the test period is long, and the timeliness of the evaluation result is low.

And 105, receiving and obtaining measurement report data uploaded by each mobile terminal in the next time period and corresponding position information to determine and obtain the network coverage quality of each grid in the next time period.

According to the method for evaluating the network coverage quality, the map is divided into a plurality of grids according to the geographic characteristics; receiving measurement report data uploaded by each mobile terminal in the current time period and corresponding position information, and determining a grid to which each measurement report data belongs according to the position information of the measurement report data; determining the network coverage quality of each grid in the current time period according to the measurement report data corresponding to each grid; receiving measurement report data uploaded by each mobile terminal in the next time period and corresponding position information to determine and obtain the network coverage quality of each grid in the next time period; and obtaining the network coverage quality evaluation result according to the network coverage quality of each grid in a plurality of time periods. The number of sampling points of measurement report data uploaded by each mobile terminal is large according to evaluation, so that the obtained evaluation result is high in objectivity.
On the basis of the first embodiment, fig. 2 is a schematic flow chart of a method for evaluating network coverage quality according to the second embodiment of the present invention, as shown in fig. 2, the method includes:
Specifically, in the second embodiment, step 201 can be implemented as follows:
step 201a, determining longitude extreme points and latitude extreme points of each region according to geographical contour lines of each region in a map;
step 201b, selecting a target area from each area;
step 201c, determining two longitude lines where the longitude extreme point of the target area is located and two latitude lines where the latitude extreme point of the target area is located;
step 201d, a rectangular area formed by the two warps and the two wefts in a surrounding mode is a grid corresponding to the target area;
step 201e, judging whether grids corresponding to all regions are obtained, if so, executing step 202; if not, the next target area is selected as the target area, and step 201c is executed.
The map can be divided into grids corresponding to the regions according to the geographic features through steps 201a to 201e, and accordingly, similar to the embodiment, each grid has a unique grid identifier corresponding to the grid.
Specifically, the measurement report data refers to a measurement report generated by a mobile terminal through calculation in an interaction process with a base station, and includes a large amount of information related to a communication network, such as a location area code, an identifier of a currently connected base station, a frequency point, a received level value, a reception quality, a delay value, strong neighbor information, and the like. It should be noted that the measurement report data does not include latitude and longitude information, that is, the measurement report data does not include location information, and therefore the location information corresponding to the measurement report data is the location information of the mobile terminal.
And step 203, determining the grid to which each measurement report data belongs according to the position information of the measurement report data.
Specifically, the correspondence between the measurement report data and the grid is determined based on the position of the grid on the map and the position information of each measurement report data. It should be noted that in this step 103, one measurement report data can only correspond to one grid, and one grid can correspond to a plurality of measurement report data.
And 204, determining the network coverage quality of each grid in the current time period according to the measurement report data corresponding to each grid.
Specifically, in the second embodiment, the step 204 can be implemented as follows:
step 204a, selecting any grid from the grids as a target grid;
and step 204b, determining the network coverage quality of the target grid according to the ratio of the number of the measurement report data meeting the edge condition in the grid and the total number of the measurement report data corresponding to each grid.
Step 204c, judging whether the network coverage quality of all grids is obtained, if so, executing step 205; if not, the next grid is selected as the target grid, and step 204b is executed.
For example, a target grid may be selected first, measurement report data corresponding to the target grid is determined, and then, the network coverage quality is determined according to a preset edge determination condition, where the edge determination condition may specifically be:
a grid is a good network coverage quality grid if the ratio of the number of measurement report data satisfying the coverage edge weak coverage definition (RSRP < -115dBm) within the grid to all measurement report data within the grid is less than 10%.
If the ratio of the number of measurement report data satisfying the coverage edge weak coverage definition (RSRP < -115dBm) in the grid to all the measurement report data in the grid is greater than or equal to 10% and less than 30%, the grid is a grid with poor network coverage quality.
If the ratio of the number of measurement report data satisfying the coverage edge weak coverage definition (RSRP < -115dBm) in the grid to all measurement report data in the grid is greater than or equal to 30%, the grid is a grid with poor network coverage quality.
Thus, the network coverage quality of all grids can be determined as above.
In other alternative embodiments, before step 204b, the total amount of measurement report data within the grid may also be determined, specifically:
before determining the network coverage quality of the target grid according to the ratio of the number of measurement report data satisfying the edge condition in the grid to the total number of measurement report data corresponding to each grid, the method further includes: when it is determined whether the total amount of the measurement report data corresponding to the target grid is smaller than the preset number threshold and the geomorphic attribute of the region corresponding to the target grid is a natural geomorphic, determining that the network coverage quality of the target grid is good and executing step 205; otherwise, step 204b is performed.
Specifically, the geographic attributes of a region may specifically include two types, one being a natural geographic, such as: water system, green land, sea, wetland, forest and other types of landforms can be classified as the natural landforms, and the other types of landforms are non-natural landforms, such as: urban, high-rise building, factory and mall, village, etc. types of landforms can be attributed to the unnatural landform. It can be known that, in the two types of geomorphic attributes, the population density of the natural geomorphic is generally small, and the number of the corresponding measurement report data that may be received by the mobile terminal is also small, whereas, the population density of the unnatural geomorphic is generally large, and the number of the corresponding measurement report data that may be received by the mobile terminal is also large, so that, by determining the total number of the measurement report data in the grid and the geomorphic attribute of the area corresponding to the grid in advance before executing step 204b, on one hand, the whole evaluation efficiency can be improved, and on the other hand, the accuracy of the obtained evaluation result is correspondingly improved due to the consideration of the influence of the geomorphic attribute on the network coverage quality.
Specifically, similar to the embodiment, in the next time period, the above steps may be repeated, that is, the measurement report data uploaded by each mobile terminal in the next time period and the corresponding location information are received and obtained, the grid to which each measurement report data belongs is determined according to the location information of the measurement report data, and the network coverage quality of each grid in the next time period is determined according to the measurement report data corresponding to each grid.
And step 206, determining the network coverage quality change trend of each grid according to the network coverage quality of each grid in a plurality of time periods.
And step 207, determining the base station to which each grid belongs according to the preset base station coverage range.
And 208, evaluating the network coverage quality of each base station according to the network coverage quality variation trend of at least one grid corresponding to each base station, and obtaining an evaluation result.
Different from the first embodiment, the second embodiment further includes steps 206 to 208. Specifically, the network coverage quality of each grid in a plurality of time periods has been obtained in the foregoing steps, and therefore, a network coverage quality variation trend of each grid may be determined according to the network coverage quality of each grid in a plurality of time periods, for example, the network coverage quality of a certain grid in the current time period is good, and the network coverage quality in the next time period is poor, that is, the variation trend of the network coverage quality of the grid is a descending trend.
Then, the base station to which each grid belongs can be determined according to the preset coverage range of the base station. Specifically, due to the characteristics of urban geographical locations, the site density of dense urban areas, general urban areas and suburban areas is different, and therefore, the coverage area of the base station is also different. And when the base station coverage radius of different areas is determined, calculating to obtain the base station coverage area according to a base station macro-cell regular hexagon area formula. The number of grids which can be covered by one base station can be calculated by calculating the ratio of the coverage area of the base station to the area of the grids, and the corresponding relation between the grids and the base station can be determined by combining the position of the base station and the position of the area corresponding to the grids on the map.
And finally, evaluating the network coverage quality of each base station according to the network coverage quality variation trend of at least one grid corresponding to each base station, and obtaining an evaluation result. For example, if the grids corresponding to a certain base station all show that the network coverage quality variation trend is good or poor, it is equivalent to that the operation of the base station itself may have a problem; or, if the grids corresponding to a certain base station all show that the network coverage quality variation trend is continuously poor, the problem corresponding to the base station is not solved; if the grids corresponding to a certain base station all show that the network coverage quality change trend is poor and good, the problem corresponding to the base station is solved. For the obtained network coverage quality situation of each base station, it may be evaluated, and an evaluation result is obtained, where the evaluation manner includes, but is not limited to, the following manners: (1) confirming the working state (accessed, not accessed, to be built and detached) of the base station; (2) confirming whether a fault alarm platform of a base station has an alarm message and confirming the alarm type; (3) confirming whether a maintenance work order for a base station associated coverage area exists on a maintenance order dispatching platform or not, and confirming the type of the work order; (4) and confirming the feedback survey result of the site survey. Therefore, the evaluation result of the base station can be obtained by evaluating the base station according to the network coverage quality condition of the base station and by using the evaluation method.
According to the method for evaluating the network coverage quality, the map is divided into a plurality of grids according to the geographic characteristics; receiving measurement report data uploaded by each mobile terminal in the current time period and corresponding position information, and determining a grid to which each measurement report data belongs according to the position information of the measurement report data; determining the network coverage quality of each grid in the current time period according to the measurement report data corresponding to each grid; receiving measurement report data uploaded by each mobile terminal in the next time period and corresponding position information to determine and obtain the network coverage quality of each grid in the next time period; and obtaining the network coverage quality evaluation result according to the network coverage quality of each grid in a plurality of time periods.
