[0035] The coverage determination method, apparatus, electronic device and storage medium provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0036] The terms "first" and "second" and the like in the specification of the present application and the accompanying drawings are used to distinguish different objects, and are not used to describe a specific order of the objects, for example, the first distance and the second distance are used to distinguish different distances, and are not used to describe a specific order of the distances.

For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

[0038] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations.

Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0039] The term "and / or" as used in this application includes using either one of two methods or using both methods simultaneously.

[0040] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0041] As described in the background art, in related technologies, servers can determine the coverage area of ​​a base station based on information input by maintenance personnel. However, maintenance personnel need to conduct on-site testing before each input, and different personnel use different testing methods, resulting in inaccurate input information. Consequently, the server may be unable to accurately determine the coverage area of ​​the base station. Therefore, this application provides a coverage area determination method, apparatus, electronic device, and storage medium. Since target path loss can characterize the signal strength variation between the target base station and the target terminal, the coverage area of ​​the target base station can be accurately and effectively determined based on this target path loss.

[0042] The coverage area determination method, apparatus, electronic device, and storage medium provided in this application can be applied to a coverage area determination system, such as... Figure 1 As shown, the coverage determination system includes server 101, base station 102, and terminal 103. Typically, in practical applications, the connection between these devices or service functions can be wireless. To easily and intuitively illustrate the connection relationships between the devices, Figure 1 Solid lines are used to represent the meaning.

[0043] The server 101 is used to obtain base station information of base station 102, terminal information of terminal 103 and geometric information of target area, and to determine the signal transmission loss between base station 102 and terminal 103 based on the base station information, terminal information and geometric information.

[0044] The base station 102 is configured to provide communication services for the terminal 103.

[0045] The terminal 103 is configured to send a signal quality optimization request to the server 101, the signal quality optimization request comprising location information of the terminal 103, the signal quality optimization request being configured to request optimization of network quality in an area where the terminal 103 is located.

[0046] Exemplarily, the electronic device performing the coverage range determination method provided by the embodiments of the present application can be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) \ virtual reality (VR) device, and the embodiments of the present application do not specially limit the specific form of the electronic device.

[0047] In addition, the electronic device can be a stand-alone physical server, or a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery network (CDN), and basic cloud computing services such as big data and artificial intelligence platforms.

[0048] As shown in the figure, in an implementation manner of the embodiments of the present application, the electronic device can include a data acquisition module, a path loss determination module, and a coverage range display module. The data acquisition module includes a terminal information acquisition module, a base station information acquisition module, and a geometric information acquisition module. Figure 2

[0049] Specifically, the terminal information acquisition module is configured to acquire terminal information of a target terminal.

[0050] The base station information acquisition module is configured to acquire base station information of a target base station.

[0051] The geometric information acquisition module is configured to acquire collective information of a target area.

[0052] The path loss determination module is configured to determine signal transmission loss between the target terminal and the target base station.

[0053] ​The coverage range display module is configured to determine and display the coverage range of the target base station.

[0054] The following takes the server 101 shown in the electronic device as an example Figure 1 to illustrate the coverage range determination method provided by the embodiments of the present application.

[0055] As shown in Figure 3 , the coverage range determination method provided by the embodiments of the present application can include S101-S103.

[0056] S101, the server obtains base station information of a target base station, terminal information of a target terminal, and geometric information of a target area.

[0057] The base station information includes position information of the target base station, a first distance between an antenna of the target base station and a horizontal plane, and a frequency of the target base station, the terminal information includes position information of the target terminal and a second distance between an antenna of the target terminal and the horizontal plane, and the geometric information includes a width of each street in a plurality of streets included in the target area, a horizontal plane area of each building in a plurality of buildings included in the target area, and a height of the each building.

[0058] It should be understood that the target base station is a base station included in the target area, and the target terminal is a terminal included in the target area.

[0059] For example, the target base station can be the base station 102 shown in the above Figure 1 , and the target terminal can be the terminal 103 shown in the above Figure 1 .

[0060] S102, the server determines a target path loss based on the base station information of the target base station, the terminal information of the target terminal, and the geometric information of the target area.

[0061] The target path loss is used to represent the signal transmission loss between the target base station and the target terminal.

[0062] In an optional implementation, the server can obtain the geometric information of the target area based on a geographic information system (GIS) and a building information modeling (BIM). Then, a signal propagation model is constructed in combination with the base station information of the target base station and the terminal information of the target terminal. And the signal transmission loss between the target base station and the target terminal is determined based on the signal propagation model.

[0063] combined Figure 3 As Figure 4 indicated, the coverage range determination method provided by the embodiment of the present application can further include S1021.

[0064] S1021, the server determines whether there is signal blockage between the target base station and the target terminal.

[0065] Continuing as Figure 4 indicated, the server determines the target path loss according to the base station information of the target base station, the terminal information of the target terminal, and the geometric information of the target area, which can specifically include S1022.

[0066] S1022, in the case that there is signal blockage between the target base station and the target terminal, the server determines the target path loss according to the average street width corresponding to the target area, the average building height corresponding to the target area, the first distance, the second distance, the third distance, and the frequency of the base station.

[0067] The third distance is the straight-line distance between the highest point of the target base station antenna and the highest point of the target terminal antenna, the average street width is determined according to the width of each street in the plurality of streets, and the average building height is determined according to the horizontal area of each building in the plurality of buildings and the height of each building.

[0068] It should be understood that in the case that there is signal blockage between the target base station and the target terminal, it is explained that the target base station and the target terminal are in a non-line-of-sight scenario, and the server can determine the target path loss according to the average street width corresponding to the target area, the average building height corresponding to the target area, the first distance, the second distance, the third distance, and the frequency of the base station.

[0069] In the embodiment of the present application, the server can determine that the target path loss satisfies the following formula:

[0070]

[0071] wherein PL represents the target path loss, represents the average street width corresponding to the target area, represents the average building height corresponding to the target area, L1 represents the first distance, L2 represents the second distance, L3 represents the third distance, and f represents the frequency of the target base station.

[0072] Optionally, the server can determine that the average building height corresponding to the target area satisfies the following formula:

[0073]

[0074] Where h represents the average building height, n represents the number of buildings included in the target area, and S i h represents the horizontal surface area of ​​the i-th building among the multiple buildings. i This represents the height of the i-th building, where i is an integer greater than or equal to 1, and 1 ≤ i ≤ n.

[0075] Optionally, the server can determine that the average street width corresponding to the target area satisfies the following formula:

[0076]

[0077] in, The value of W represents the average street width, m represents the number of streets included in the target area. j Let represent the width of the j-th street, where j is an integer greater than or equal to 1, and 1 ≤ j ≤ m.

[0078] Combination Figure 4 ,like Figure 5 As shown, in one implementation of this application embodiment, the server determines the target path loss based on the base station information of the target base station, the terminal information of the target terminal, and the geometric information of the target area, and may further include S1023-S1024.

[0079] S1023. If there is no signal obstruction between the target base station and the target terminal, the server determines whether the fourth distance is less than the breakpoint distance.

[0080] The fourth distance is the distance between the target base station and the target terminal. The breakpoint distance is determined based on the frequency of the target base station, the first distance, and the second distance.

[0081] It should be understood that if there is no signal obstruction between the target base station and the target terminal, it indicates that they are in a line-of-sight scenario. In this case, the server can determine a fourth distance based on the location information of both the target base station and the target terminal. This fourth distance can also be understood as the horizontal distance between the target base station and the target terminal. Furthermore, it needs to be determined whether this fourth distance is less than the breakpoint distance.

[0082] Optionally, the server can determine that the distance to the breakpoint satisfies the following formula:

[0083]

[0084] Where B represents the distance to the breakpoint, L1 represents the first distance, L2 represents the second distance, f represents the frequency of the target base station, a represents the first parameter, c represents the second parameter, and a > 0, c > 0.

[0085] For example, the first parameter can be 1, and the second parameter can be the signal propagation speed in the air, i.e., 3.0 × 10⁻⁶. 8 m / s (meters per second).

[0086] S1024. If the fourth distance is less than the breakpoint distance, the server determines the target path loss based on the third distance and the frequency of the target base station.

[0087] Specifically, the server can determine that the target path loss satisfies the following formula:

[0088] PL = 22.0lgL3 + 28.0 + 20lgf

[0089] Where PL represents the target path loss, L3 represents the third distance, and f represents the frequency of the target base station.

[0090] Combination Figure 5 ,like Figure 6 As shown, in one implementation of this application embodiment, the server determines the target path loss based on the base station information of the target base station, the terminal information of the target terminal, and the geometric information of the target area, and may further include S1025.

[0091] S1025. When the fourth distance is greater than or equal to the breakpoint distance, the server determines the target path loss based on the first distance, the second distance, the third distance, the frequency of the target base station, and the breakpoint distance.

[0092] Specifically, the server can determine that the target path loss satisfies the following formula:

[0093] PL=40lgL3+28.0+20lgf-9lg((B) 2 +(L1-L2) 2 )

[0094] Where PL represents the target path loss, L1 represents the first distance, L2 represents the second distance, L3 represents the third distance, f represents the frequency of the target base station, and B represents the breakpoint distance.

[0095] S103. The server determines the coverage area of ​​the target base station based on the target path loss.

[0096] It should be understood that since the target path loss can characterize the signal strength variation between the target base station and the target terminal, the coverage area of ​​the target base station can be accurately determined based on this target path loss.

[0097] The technical solutions provided by the above embodiments can bring at least the following beneficial effects: As can be seen from S101-S103, the server can acquire base station information of a target base station, terminal information of a target terminal, and geometric information of a target area, and determine a target path loss according to the base station information, the terminal information, and the geometric information. Then the server can determine a coverage range of the target base station based on the target path loss. In the embodiments of the present application, since the target path loss can represent the signal strength variation between the target base station and the target terminal, the coverage range of the target base station can be accurately and effectively determined based on the target path loss.

[0098] In combination Figure 3 As Figure 7 indicated, the range coverage determination method provided by the embodiments of the present application can further include S104-S105.

[0099] S104, the server determines a target sub-area in response to a signal quality optimization request sent by a target terminal.

[0100] The target sub-area is a sub-area in the target area where the target terminal is currently located.

[0101] It should be understood that when the target terminal is in the target sub-area and the signal strength of the target sub-area is less than or equal to the signal strength threshold, it indicates that the signal strength of the target sub-area is small and cannot meet the service requirements of the target terminal. At this time, the target terminal sends a signal quality optimization request to the server, and the signal quality optimization request includes the location information of the target terminal. The signal quality optimization request is used to request optimization of the network quality of the target sub-area.

[0102] S105, the server displays the target sub-area based on a preset color.

[0103] It should be understood that the server displays the target sub-area based on a preset color, which can facilitate the operation and maintenance personnel to quickly locate the area with poor signal quality (for example, the target sub-area), so as to optimize the network of the area with poor signal quality.

[0104] For example, the preset color can be red.

[0105] In an optional implementation, the target area can include a plurality of sub-areas, and the server can configure different colors for the plurality of sub-areas respectively based on signal strengths of the plurality of sub-areas. When a signal strength of a target sub-area is less than or equal to a signal strength threshold, the server can update a color configured for the target sub-area to the preset color. When the signal strength of the target sub-area is greater than the signal strength threshold, that is, the signal strength of the target sub-area returns to a normal level, the server can update the preset color to the color configured for the target sub-area.

[0106] The embodiments of the present application can divide the functions of the electronic device (including the server) according to the above-mentioned method examples, for example, each function module can be divided according to each function, or two or more functions can be integrated into one processing module. The integrated module can be realized in the form of hardware or in the form of a software function module. It should be noted that the division of the modules in the embodiments of the present application is illustrative, and is only a logical function division. When actually implemented, another division mode can be used.

[0107] In the case of dividing each function module according to each function, Figure 8 A possible structure diagram of the coverage range determination apparatus involved in the above-mentioned embodiments is shown, as Figure 8 The coverage range determination apparatus 20 can include an acquisition module 201 and a determination module 202.
