It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented, for example, in sequences other than those illustrated or otherwise described herein.

The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
In the conventional daily optimization maintenance process of network operation, network coverage areas of different places need to be detected and changed, so that the coverage areas of cells need to be detected, and the effectiveness and reliability of the network used by users need to be ensured especially in important activity periods and holidays. For example, different sites where the network operates may include hospitals, super-providers, transportation hubs, residential areas, office buildings, universities, scenic spots and the like, in the prior art, the cell industrial parameters are manually acquired, or the coverage range of the cell is detected by manually reaching an optimized site, which not only takes long time, but also has low accuracy, especially after the network base station changes, for example, a new base station is added or a base station is removed, the manual update is often not timely, and omission occurs, so that a method for detecting the coverage range of the cell with higher precision and timeliness is urgently needed.
Fig. 1 is a flowchart of a method for detecting a cell coverage according to an embodiment of the present invention, as shown in fig. 1, where the method for detecting a cell coverage in this embodiment may include:
s101, acquiring a geographical scene area, and acquiring base station information in the geographical scene and a preset peripheral border area, wherein the geographical scene area belongs to the preset peripheral border area.
Specifically, the base information of the geographic scene can be searched, and the geographic scene border, the base station information and the preset peripheral border area can be crawled. The basic information may include a city name, a scene name, etc. where the geographic scene is located, which is not limited in this embodiment.
The geographical scene in this embodiment may include a scene of network operation at a specific geographical location, for example, a scene including a hospital, a supermarket of a store, a transportation hub, a residential area, an office building, a university, a scenic spot, and the like. In an alternative embodiment, the basic information of the geographical scene, such as the basic information of xx residential areas, is searched by means of the internet to obtain the geographical scene area, and the border area of the geographical scene area is crawled, and the border area of the geographical scene area also comprises the border range of the geographical scene area, namely the border of the geographical scene. The frame located at the preset distance outside the geographic scene area can be obtained, namely, the area corresponding to the frame with the preset distance is obtained, and the preset peripheral frame area is obtained. The base station information distributed in the preset peripheral border region may also be obtained, for example, the base station information may include information such as a cell name, a cell longitude, a cell latitude, a base station altitude, an azimuth angle, a cell frequency band, a base station type, and the like. In order to ensure the accuracy of detection, the preset distance is not set too small, which causes too few cells in the preset peripheral border area, and too large, which causes too many matched cells, so that the preset distance can be set to be 0.5-1 times of the inter-station distance of the geographic scene area.
S102, generating a circumscribed border area of the geographic scene according to longitude and latitude information of the geographic scene.
In this embodiment, according to the longitude and latitude information of the geographic scene, for example, the maximum longitude information, the maximum latitude information, the minimum longitude information and the minimum latitude information of the geographic scene, and the maximum longitude and latitude information and the minimum longitude and latitude information generate an circumscribed border area of the geographic scene, the circumscribed border area may include a rectangular border area.
And S103, according to the preset peripheral border region, the circumscribed border region and the base station information, obtaining the base stations positioned in the preset peripheral border and outside the geographic scene border, and determining that the base station cell covers the geographic scene region.
In the embodiment, the base stations located inside the preset peripheral border and outside the geographic border are determined mainly through the preset peripheral border area, the external border area and the base station information, so that whether the base station cell covers the geographic scene area or not is determined. In an alternative embodiment, whether a base station located within a geographical scene area covers a geographical scene may be obtained by a ray algorithm, so the present invention primarily determines whether a base station located outside the geographical scene area can cover the geographical scene.
The embodiment of the invention can improve the accuracy of detecting the coverage area of the base station cell in the geographic scene, and simultaneously improve the detection speed, and especially can reduce the operation after the network base station is changed, and improve the detection effectiveness and reliability.
In combination with the embodiment shown in fig. 1, generating the circumscribed border region of the geographic scene according to the longitude and latitude information of the geographic scene may be further achieved by specifically obtaining the minimum longitude and latitude information and the maximum longitude and latitude information of the geographic scene respectively, and obtaining the longitude and latitude information of the circumscribed border according to the minimum longitude and latitude information and the maximum longitude and latitude information to generate the circumscribed border region.
Referring to fig. 2, fig. 2 is a schematic diagram of a geographic scene provided by an embodiment of the present invention, as shown in fig. 2, after a geographic scene area is obtained, and a corresponding geographic scene frame 21 (in an alternative embodiment, the geographic scene area may be obtained according to a boundary of the geographic scene area, and the corresponding longitude and latitude information includes the boundary), the maximum longitude and latitude information and the minimum longitude and latitude information in the geographic scene area may be further obtained according to the longitude and latitude information of the geographic scene, for example, the longitude and latitude information of the boundary of the geographic scene area is obtained according to the longitude and latitude information of the boundary of the geographic scene area, and the maximum longitude and latitude information, the maximum latitude information, the minimum longitude and the minimum latitude information are obtained, and according to various combinations of the maximum longitude and latitude information and the minimum longitude and latitude information, for example, (minlon, maxlat), (maxlat ), and maxlat generate an circumscribed frame area corresponding to the geographic scene area, for example, the circumscribed frame area included in the circumscribed frame 22 shown in fig. 2, and the geographic scene area includes or coincides with the circumscribed frame area, wherein (lalat), (maxlat, and maxlat) are circumscribed vertex and maxlat, respectively.
With further reference to the embodiment shown in fig. 1, according to the preset peripheral frame area, the external frame area and the base station information, obtaining the base station located in the preset peripheral frame and outside the geographic scene frame can be achieved by specifically obtaining the central longitude and latitude information of the external frame area, and obtaining the intra-division longitude and latitude information according to the central longitude and latitude information and the longitude and latitude information of the external frame; and obtaining the base stations positioned in the preset peripheral frame and outside the geographic scene frame according to the base station information, the center longitude and latitude information and the internal dividing longitude and latitude information.
And wherein obtaining the intra-split longitude and latitude information according to the center longitude and latitude information and the longitude and latitude information of the circumscribed frame comprises: dividing the circumscribed frame region into a plurality of local regions according to the longitude and latitude information of the center and the longitude and latitude information of the circumscribed frame boundary, and obtaining corresponding internal dividing longitude and latitude information according to the longitude and latitude information of the vertex corresponding to the local region.
With specific reference to the area corresponding to the circumscribed frame shown at 22 in fig. 2, the latitude and longitude information of the center of the circumscribed frame area may be obtained according to four vertices of the circumscribed frame area, for example, the latitude and longitude information of the center corresponds to the center point Z of the circumscribed frame area, and the latitude and longitude information of the center z_lat and the latitude information of the center z_lon may be obtained by using formula one.
Z_lon＝min lon+(max lon-min lon)/2
Z_lat=min lat+ (max lat-min lat)/2 equation one
And further obtaining inner splitting longitude and latitude information according to the central longitude and latitude information and the vertex longitude and latitude information of the circumscribed frame, for example, 4 intersection points (not shown) can be obtained with the circumscribed frame boundary by drawing a horizontal line and a vertical line through the central point Z according to the central longitude and latitude information corresponding to the central point Z, the circumscribed frame region is divided into 4 corresponding local regions (not shown), and further the inner splitting point A, B, C, D and the longitude and latitude information corresponding to each local region are respectively obtained according to the vertex (namely the 4 intersection points) longitude and latitude information corresponding to each local region by adopting a formula II.
A_lon＝Z_lon-(Z_lon-minlon)/2
B_lon＝Z_lon+(Z_lon-minlon)/2
C_lon＝Z_lon+(Z_lon-minlon)/2
D_lon＝Z_lon-(Z_lon-minlon)/2
A_lat＝Z_lat+(Z_lat-minlat)/2
B_lat＝Z_lat+(Z_lat-minlat)/2
C_lat＝Z_lat-(Z_lat-minlat)/2
D_lat=z_lat- (z_lat-min lat)/2 formula two
The base stations within the predetermined peripheral border 23 and outside the geographic scene border 21 are then determined based on the base station information, the center longitude and latitude information (e.g., corresponding to center point Z), and the intra-partition longitude and latitude information (e.g., corresponding to intra-partition point A, B, C, D).
In an alternative embodiment, the inner splitting point A, B, C, D may be further split again with the center, to obtain inner splitting points A1, A2, A3, A4, B1, B2, B3, B4, C1, C2, C3, C4, D1, D2, D3, D4, replacing the center point Z with the center point a with reference to the formula two and obtaining inner splitting points A1, A2, A3, A4, and so on, replacing the center point Z with B, C, D, respectively, to obtain inner splitting points B1, B2, B3, B4, C1, C2, C3, C4, D1, D2, D3, D4. The vertex longitude and latitude information corresponding to the local area in this embodiment is similar to the principle and implementation of obtaining the internal splitting point A, B, C, D, and will not be described here again. In an alternative embodiment, the number of the split points may be 4 or 16, and more split points and corresponding longitude and latitude information may be further obtained according to the size of the geographical scene area, where the number of split points is generally 16, but the embodiment is not limited thereto. According to the embodiment, a proper number of internal splitting points can be obtained according to the size of a geographic scene, and the operation can be reduced, so that the detection efficiency is improved.
In connection with the embodiment shown in fig. 2, the determining that the base station cell covers the geographical scene area is further implemented in a manner that, specifically, according to longitude and latitude information of the base station, longitude and latitude information of the center and internal dividing longitude and latitude information are obtained, an included angle of the base station facing the frame of the geographical scene is obtained; if the detection result shows that at least one included angle is matched with the azimuth angle of the base station, the base station is located in the preset peripheral frame and outside the geographic scene frame, and the coverage of the base station cell to the geographic scene area is determined.
Referring to the base station j shown in fig. 2, an included angle of the base station j facing the frame of the geographic scene is obtained according to longitude and latitude information corresponding to the base station j, central longitude and latitude information (corresponding to a central point, for example, a point Z) or intra-split longitude and latitude information (corresponding to an intra-split point, for example, a point D1), and if the detected included angle matches with the azimuth angle of the base station, it is determined that the base station cell can cover the geographic scene area. For each base station, for example, a plurality of angles of the base station facing the geographic scene frame are obtained by detecting longitude and latitude information of the base station and different centers and longitude and latitude information of internal division, and if at least one angle is detected to be matched with the azimuth angle of the base station, the coverage of the base station cell to the geographic scene area is determined. And if the detection result shows that the included angle is not matched with the azimuth angle of the base station, determining that the base station cell cannot cover the geographical scene area.
Similarly, referring to fig. 2, the base stations located outside the circumscribed frame 22 and inside the preset peripheral frame 23 may also determine that the base station cell covers the geographic scene area by classifying the longitude and latitude information of the base station with the longitude and latitude information of the center (and/or).
In an alternative embodiment, the base stations belonging to the geographical scene frame are determined according to the base station information and the geographical scene frame. Specifically, through a ray algorithm, a base station is taken as a ray vertex to obtain an intersection point with a geographical frame, if the number of the intersection points is 1, the base station is determined to belong to the geographical scene frame, and a cell of the base station can cover a geographical scene area; if the number of the intersection points is 2, it is determined that the base station does not belong to the geographical scene frame, and whether the base station cell can cover the geographical scene area needs to be further detected. When the base station is located in the preset peripheral frame and outside the geographic birth channel frame, the specific implementation manner of detecting whether the base station cell covers the geographic scene area is described in detail above, and will not be repeated here.
According to the method and the device for detecting the coverage area of the base station cell in the geographic scene, the accuracy of detecting the coverage area of the base station cell in the geographic scene can be improved, meanwhile, the detecting speed is improved, and particularly after the network base station changes, the operation can be reduced, and the detecting effectiveness and reliability are improved.
