Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a network performance evaluation method, apparatus, device, and storage medium. Background Art

[0002] Currently, with the continuous development of communication technology, the number of communication network facilities being built is increasing, and the coverage of communication networks is also becoming increasingly larger. As the coverage breadth of communication networks gradually approaches saturation, the planning direction of communication networks has begun to develop in the direction of deep network coverage. As one of the main directions of deep network coverage, mobile network coverage inside buildings (such as indoors) has become a current hot issue. Therefore, it is necessary to evaluate indoor network performance, so as to determine the current network coverage by analyzing relevant performance indicators of network coverage. In related technologies, the evaluation method for indoor coverage performance under outdoor macro base station solutions mainly uses the link budget method to evaluate the coverage radius of the entire indoor shallow coverage based on the scenario, or to simulate and predict the indoor network through network modeling to achieve the evaluation of indoor coverage performance of buildings.

[0003] However, the aforementioned methods all use qualitative methods to assess shallow coverage of buildings, using the overall coverage of base stations as a target. This roughly assesses the shallow coverage performance of base stations, resulting in low accuracy. Consequently, the evaluation of shallow coverage performance of base stations is inefficient and inaccurate. Summary of the Invention

[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0032] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" and "a plurality of" refer to two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not limit them to be different.

[0033] Currently, mobile network planning primarily involves achieving network coverage within a building's interior (indoors) by using outdoor macro sites (e.g., base stations) to provide indoor coverage, or by deploying indoor distribution systems for direct coverage. Current network performance evaluation methods for outdoor macro sites providing indoor coverage primarily use qualitative methods to roughly identify buildings that may have coverage issues. However, existing methods (such as those described in the background) often provide simple qualitative assessments of coverage conditions. Furthermore, these evaluations fail to fully account for losses incurred during network transmission (e.g., when penetrating walls), potentially leading to significant deviations in the results.

[0034] In addition, the current assessment of outdoor macro base station coverage and indoor shallow coverage is rather rough, and there is no fixed standard. The coverage assessment methods for a single building and all buildings in an overall area are relatively independent, and it is not possible to effectively combine the coverage assessment results of a single building and all buildings in an overall area to evaluate the shallow coverage performance of the target base station network based on the connection between the two.

[0035] A network performance evaluation method provided in an embodiment of the present application can be applied to a network performance evaluation system. Figure 1 FIG. 1 shows a structural diagram of the network performance evaluation system. Figure 1 As shown, the network performance evaluation system 20 includes: an electronic device 21, a server 22 and a plurality of base stations 23. The server 22 is connected to the electronic device 21 and the plurality of base stations 23 respectively.

[0036] The network performance evaluation system 20 can be used in the Internet of Things. The network performance evaluation system 20 can include hardware such as multiple central processing units (CPUs), multiple memories, and storage devices storing multiple operating systems.

[0037] The electronic device 21 can be used in the Internet of Things to realize data processing. For example, the electronic device 21 can determine the signal strength corresponding to each target unit area in the target area based on the network loss parameters, target base station information, and environmental information corresponding to the target area, and output the signal strength corresponding to each target unit area.

[0038] The server 22 is used to acquire data. For example, a database may be provided in the server 22 . The database stores network loss parameters and environmental information corresponding to the target area for the electronic device 21 to process the data.

[0039] Optionally, the server 22 may also connect with multiple base stations 23 to obtain operating parameters and location information corresponding to each base station, obtain target base station information, and store it in a database.

[0040] The base station 23 is a base station in the target area, and is used to provide its own operating parameters and location information for the electronic device to process data.

[0041] Optionally, the base station 23 may upload the current corresponding operating parameters and location information in real time.

[0042] In one design, the electronic device 21 may also directly connect to the base station 23 to obtain the operating parameters and location information corresponding to each base station.

[0043] A network performance evaluation method provided in an embodiment of the present application is described below with reference to the accompanying drawings.

[0044] like Figure 2 As shown, a network performance evaluation method provided in an embodiment of the present application includes S201-S204:

[0045] S201. Obtain network loss parameters, target base station information, and environmental information corresponding to a target area.

[0046] Among them, the target area includes multiple buildings, and the network loss parameter is used to indicate the loss caused by the building to the network signal transmission. The network loss parameters corresponding to buildings of different building types are different. The target base station information is used to indicate the operating parameters and location information of the target base station corresponding to the target area, and the environmental information is used to indicate the location information and building size of each building.

[0047] It can be understood that the target area is the area that needs to be investigated and analyzed, that is, the area that needs to be evaluated for network performance.

[0048] Optionally, the target area can be an administrative area (such as Province A, City B, District / County C, etc.), a specific scenario area (such as an industrial park, educational park, hospital, school, residential area, etc.) or other custom areas.

[0049] Optionally, as shown in Table 1, the network loss parameter may be a mapping table of outer wall penetration losses corresponding to different building types and different network frequency bands.

[0050] Table 1

[0051]

[0052] Optionally, the frequency band refers to the frequency range of radio waves corresponding to the base station.

[0053] Optionally, a signal transmitting device can be set at a preset position, and at least one signal receiving device can be set in the building corresponding to each building type of different building types. By analyzing the parameters of the signal received by the signal receiving device, the outer wall penetration loss corresponding to different building types in different frequency bands can be determined.

[0054] Optionally, as shown in Table 1, the network loss parameters may further include an indoor step loss mapping table corresponding to different building types and different network frequency bands.

[0055] It should be noted that indoor step loss can be understood as the loss of network signals caused by transmission distance in indoor space.

[0056] Optionally, a signal transmitting device can be set at a preset position, and multiple signal receiving devices can be set at different positions in the building corresponding to each building type in different building types. By analyzing the parameters of the signal received by the signal receiving device, the indoor step loss corresponding to different building types in different frequency bands can be determined.

[0057] Optional, such as Figure 3 As shown, in the embodiment of the present application, the influence of the outer wall of the building on the signal transmission inside the building can be determined by the outer wall penetration loss, and the influence of different positions in the building on the signal transmission can be determined by the indoor step loss.

[0058] It should be noted that when acquiring building dimensions, only the building's outer outline is typically obtained, and information such as the building's internal structure, wall information, and building materials cannot be obtained. Therefore, after introducing the outer wall loss parameter, the additional indoor step loss can also be used to indicate signal loss caused by the building's internal structure, wall information, and building materials.

[0059] Optionally, the target base station corresponding to the target area is at least one base station in the target area.

[0060] Optionally, the target base stations corresponding to the target area may also include base stations within a preset range outside the boundary of the target area, such as base stations within two kilometers outside the boundary of the target area.

[0061] Optionally, as shown in Table 2, the location information of the target base station may be geographical location information corresponding to the target base station, such as longitude and latitude information corresponding to the target base station.

[0062] Optionally, as shown in Table 2, the target base station information may also include information such as the operator and the operating status.

[0063] Table 2

[0064] base station longitude latitude Operator state A 120.933E 31.0219N X Running

[0065] Optionally, the operating status is used to indicate the current operating status of the base station, such as to be built, to be connected to the network, trial operation, existing network operation, etc.

[0066] Optionally, as shown in Table 3, the operating parameter of the target base station may be at least one of the multiple operating parameters listed in Table 3 corresponding to each sector of at least one sector corresponding to the target base station.

[0067] Optionally, the environmental information may be Geographic Information System (GIS) map data within the target area, including ground feature information, terrain information, elevation information, vector information, etc. of the target area.

[0068] Optionally, the feature information of the target area may include location information, size information, shape information, etc. of each building in the target area.

[0069] Optionally, the environmental information may further include information about points of information (POI), such as the name of each feature.

[0070] Table 3

[0071]

[0072] Table 4

[0073]

[0074] Table 5

[0075]

[0076] Optionally, as shown in Table 4 and Table 5, the operating parameters of the target base station may also include at least one of the multiple operating parameters listed in Table 4 and Table 5 for each cell in at least one cell corresponding to each sector.

[0077] It can be understood that the specific data in Tables 1, 2, 3, 4 and 5 above are only exemplary data. In specific implementations, the above data will change according to changes in factors such as the target area, data acquisition time, and target base station.

[0078] S202: Input network loss parameters, target base station information, and environmental information into a preset simulation model, and output the signal strength corresponding to each target unit area in the target area.

[0079] The target unit area is a unit area inside a building in the target area.

[0080] Optionally, the signal strength corresponding to each target unit area may be the signal strength corresponding to each square meter inside a building in the target area.

[0081] Optionally, the preset model can realize simulation prediction of the network status of the target area based on network loss parameters, target base station information, and environmental information, thereby obtaining the signal strength corresponding to each unit area (such as each square meter) in the target area.

[0082] Optionally, the location information of each building in the target area can be determined based on the environmental information of the target area, and based on the location information of each building in the target area and the location of each unit area, the unit area inside the building in the target area can be determined, and then the signal strength corresponding to each target unit area in the target area can be output.

[0083] Optionally, the signal strength corresponding to each target unit area may be a network signal parameter corresponding to each target unit area obtained through a preset simulation model.

[0084] Optionally, the network signal parameters corresponding to each target unit area can be selected according to specific usage needs.

[0085] Exemplarily, when the current network is a 5G network, the network signal parameter corresponding to each target unit area may be the synchronization reference signal received power (SS RSRP) corresponding to each unit area.

[0086] In a possible implementation, for the target base station information and environmental information, information of all base stations and environmental information within a preset area may be obtained. The preset area may be an area including the target area.

[0087] For example, the preset area can be City A, and the target area is County A in City A. First, all base station information and environmental information in City A are obtained, and the target area County A that needs attention is determined. Then, based on all base station information and environmental information in City A, the target base station information and environmental information of County A are determined.

[0088] Optionally, there may be multiple target areas, for example, the target areas may be County A and County B in City A.

[0089] In one design, a relationship function between the floor and the height of the unit area can also be set, and the relationship function can be input into the preset model.

[0090] It should be noted that, for unit areas with the same horizontal position (projection position), due to different heights of the unit areas (ie, different floors corresponding to the unit areas), the signal strengths corresponding to the unit areas may also be different.

[0091] Optionally, the relationship function between the floor and the height of the unit area is shown in Formula 1:

[0092] h b =(n-1)h1+h u Formula 1

[0093] Among them, h b is the height of the unit area, n is the floor corresponding to the unit area, h1 is the average height of a single floor, h u It is the preset height parameter.

[0094] Alternatively, the height of the building may be determined based on the building dimensions, and based on the number of floors in the building, the average height of a single floor may be determined.

[0095] Optionally, the preset height parameters can be selected according to specific evaluation needs.

[0096] For example, the network coverage performance in the embodiment of the present application can be used to indicate the perception of the network status of the target base station by the network user corresponding to the target base station. At this time, when determining the influence of the height of the unit area on the signal strength, the preset height parameter can be determined as the preset user height (that is, h in this case). u The user height is the preset height of the user or the height of the terminal device from the ground), so that the network performance evaluation results are closer to the user's perception, and the accuracy of the network coverage performance evaluation is further improved.

[0097] Optionally, when the preset height parameter is a preset user height, the preset user height may be further determined based on the current network conditions and the evaluation object.

[0098] For example, the current fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) services mainly include voice services and data services. When the object of network performance evaluation is mainly 5G services, the preset user height can be 1-1.7m; when the object of network performance evaluation is mainly data services in 5G services, the preset user height can be set to 1-1.5m; when the object of network performance evaluation is mainly voice services in 5G services, the preset user height can be set to 1.5-1.7m.

[0099] S203 : Determine a plurality of first areas in the target area based on the signal strength corresponding to each target unit area in the target area.

[0100] Each of the multiple first areas includes a target unit area in a building where the signal strength is greater than or equal to a preset strength.

[0101] Optionally, the preset strength may be determined based on information such as the current network status and the network operating environment, according to specific usage needs, or in combination with relevant industry standards.

[0102] Exemplarily, the preset strength may be -115 dBm. When the signal strength of the target unit area in the building is greater than or equal to -115 dBm, it is determined that the target unit area belongs to the first area.

[0103] Optionally, one building corresponds to one first area, and the signal strength corresponding to each target unit area in the building can be determined to determine the target unit area in the building whose signal strength is greater than or equal to a preset strength, thereby determining the first area corresponding to the building.

[0104] It should be noted that due to network coverage issues, for a certain building, the area of ​​the building may be different from the area of ​​the first area corresponding to the building, and the area of ​​the building may be less than or equal to the area of ​​the first area corresponding to the building.

[0105] In one possible implementation, the signal strengths of all target unit areas in the target area may be divided into N+1 signal strength intervals using N preset thresholds, and the target area may be further divided into N+1 sub-areas using the target unit areas corresponding to each signal strength interval. Furthermore, based on the preset signal strengths, a target signal strength interval that meets the preset strength is determined, and each first area in the target sub-area is determined based on the target sub-areas corresponding to the target signal strength intervals.

[0106] Optionally, the required target signal strength interval may be determined according to a specific performance evaluation standard or evaluation requirement, and then the area of ​​each first region in the target subregion may be determined according to the target subregion corresponding to the target signal strength interval.

[0107] Optionally, the N preset thresholds may be preset thresholds determined according to specific usage requirements or relevant industry standards.

[0108] Exemplarily, when the signal strength corresponding to each unit area is the SS RSRP parameter corresponding to each unit area, the N preset thresholds can be 8 preset thresholds, namely -120dBm, -115dBm, -112dBm, -110dBm, -105dBm, -100dBm, -95dBm, and -90dBm.

[0109] Optionally, according to the above 8 preset thresholds, the signal strengths corresponding to all the obtained unit areas can be divided into 9 sets, namely SS RSRP0<-120dBm; -120dBm≤SS RSRP1; -115dBm≤SS RSRP2; -112dBm≤SS RSRP3; -110dBm≤SS RSRP4; -105dBm≤SS RSRP5; -100dBm≤SS RSRP6; -95dBm≤SSRSRP7; -90dBm≤SS RSRP8, and each sub-area is the area corresponding to each set.

[0110] Furthermore, when the preset signal strength is -115 dBm, the sub-area corresponding to SS RSRP2 is determined as the target sub-area, and then the first area corresponding to each building in the target sub-area is determined based on the target sub-area.

[0111] S204: Determine the network performance of the target base station according to the area of ​​each first area in the multiple first areas.

[0112] Optionally, the network performance of the target base station may be the shallow network coverage performance of the target base station for buildings in the target area. The shallow network coverage performance is used to indicate the basic network coverage capability of the target base station for buildings in the target area (such as whether the user can currently perceive the network).

[0113] Optionally, the signal strength corresponding to each unit area in the target area can be used to determine the areas of all unit areas corresponding to signal strengths that meet preset conditions, and then the network coverage performance of the target base station for the target area can be determined based on the areas of all unit areas corresponding to signal strengths that meet preset conditions.

[0114] It should be noted that the network performance evaluation method in the embodiment of the present application is mainly used in scenarios where outdoor macro stations provide shallow coverage indoors.

[0115] In an embodiment of the present application, first, a network loss parameter corresponding to the target area is obtained to indicate the loss caused by the building to the network signal transmission, target base station information is obtained to indicate the operating parameters and location information of the target base station corresponding to the target area, and environmental information is obtained to indicate the location information and building size of each building; the network loss parameter, target base station information, and environmental information are input into a preset simulation model, and the signal strength corresponding to each target unit area inside the building in the target area is output, and then, based on the signal strength corresponding to each target unit area in the target area, the first area in each building in the target area where the signal strength is greater than or equal to the preset strength is determined, and based on the area of ​​each first area, the network performance of the target base station is determined. Through the above method, based on the network loss parameter, target base station information, and environmental information corresponding to the target area, the signal strength corresponding to the target unit area inside each building in the target area can be obtained based on the preset simulation model, and then the first area in each building where the signal strength is greater than or equal to the preset strength is determined, and the network performance of the target base station is determined based on the area of ​​each first area, thereby improving the evaluation accuracy of the shallow coverage performance of the network, so as to improve the efficiency and accuracy of evaluating the shallow coverage performance of the target base station network.

[0116] In one design, Figure 4 As shown, a network performance evaluation method provided in an embodiment of the present application further includes S301-S302:

[0117] S301: Determine the building type of each of the multiple buildings included in the target area according to the building size of each of the multiple buildings.

[0118] Among them, the building types include: the first building type, the second building type, and the third building type. The height of the building corresponding to the first building type is less than or equal to the first height, the height of the building corresponding to the second building type is greater than the first height and less than the second height, and the height of the building corresponding to the third building type is greater than or equal to the second height, and the second height is greater than the first height.

[0119] Optionally, the building size of each building may include the height of each building, and the building type of each building is determined according to the height of each building.

[0120] Optionally, the first height and the second height can be determined according to specific usage needs. It can be understood that due to the different heights of buildings, the strength requirements of the buildings are different, and the building materials used in the walls of the buildings will also be different, so the corresponding network loss parameters will also be different.

[0121] For example, the first height can be 20m and the second height can be 40m. In this case, buildings with a height less than or equal to 20m are buildings corresponding to the first building type, buildings with a height greater than 20m and less than 40m are buildings corresponding to the second building type, and buildings with a height greater than or equal to 40m are buildings corresponding to the third building type.

[0122] Optionally, when the target base station covers the target area, the buildings in the target area may be modeled to obtain size information of each building in the target area, and the obtained size information of each building in the target area may be stored as a building layer file.

[0123] Optionally, the building layer file can be a file in the BIL format or a file in the Tab format.

[0124] Optionally, determining the building type of each of the multiple buildings can be understood as assigning a category corresponding to each of the multiple buildings.

[0125] Optionally, before assigning a category corresponding to each of the multiple buildings, it is necessary to ensure that the building layer file is a file in Tab format.

[0126] Optionally, the building layer file may also include building function classification information for each building.

[0127] In one design, the building type of each building can also be determined based on the building function classification information of each building included in the building layer file.

[0128] For example, the buildings corresponding to the first building type may be buildings corresponding to functional classification information such as urban villages, street shops, school teaching buildings, and rooftop sports venues; the buildings corresponding to the second building type may be buildings corresponding to functional classification information such as school libraries, school dormitories, hotels, medium-sized shopping malls, hospitals, and office buildings; the buildings corresponding to the third building type may be buildings corresponding to functional classification information such as high-end hotels, large shopping malls, enclosed large sports halls, and high-end residential communities.

[0129] Optionally, the functional classification information corresponding to each building type can be adjusted and changed according to specific usage needs.

[0130] For example, in one possible implementation, the building type corresponding to a small school dormitory (such as a dormitory for a primary school or a school for after-school tutoring) can be determined as the first building type.

[0131] Optionally, the building size may include the individual projected size of each building (such as the length of the building, the width of the building), and then the projected area of ​​the building is determined by the size of the building.

[0132] In one design, the architectural type of each building may also be determined based on the size of the individual projected area of ​​each building.

[0133] For example, the building corresponding to the first building type may be a building with a single projected area less than or equal to 100 square meters; the building corresponding to the second building type may be a building with a single projected area greater than 100 square meters and a single projected area less than or equal to 300 square meters; the building corresponding to the third building type may be a building with a single projected area greater than 300 square meters.

[0134] S302: Determine a network loss parameter corresponding to each of the first building type, the second building type, and the third building type.

[0135] Optionally, the network loss parameters corresponding to each building type in different frequency bands can be determined based on Table 1 and Table 2 above.

[0136] It should be noted that for different building types, the corresponding wall construction requirements will also be different, resulting in large differences in the network loss parameters corresponding to different building types.

[0137] In an embodiment of the present application, by determining the building types corresponding to different buildings in the target area, and then determining the network loss parameters corresponding to the buildings based on the building types, when simulating and predicting the signal strength corresponding to each unit area in the target area, the different positions of each target unit area inside the building and the different building types of the buildings corresponding to each target unit area are fully considered, and the impact on the signal strength corresponding to the target unit area is used to improve the accuracy of the evaluation of the network performance of the base station.

[0138] In one design, Figure 5 As shown, in a network performance evaluation method provided by an embodiment of the present application, the above S204 further includes S401-S403:

[0139] S401: Determine the area of ​​each first area among a plurality of first areas, and determine the area of ​​each building among a plurality of buildings.

[0140] Optionally, the area of ​​each of the multiple buildings may be determined based on the size information of the buildings in the environmental information.

[0141] Optionally, the area of ​​the building may be the projected area of ​​the building.

[0142] S402: For any building among the multiple buildings, determine a target ratio between an area of ​​a first region corresponding to any building and an area of ​​any building.

[0143] Optionally, the target ratio is calculated as shown in Formula 2, which can be determined by the area of ​​the first region corresponding to the building and the area of ​​the building:

[0144]

[0145] Among them, J i is the target ratio corresponding to building i, T i is the area of ​​the first region corresponding to the building, S i is the area of ​​building i.

[0146] Optional, J i It can be used to indicate the network coverage performance parameters of the target base station for building i.

[0147] For example, when it is necessary to determine the network coverage performance of the target base station for building A, the area of ​​building A is 100 square meters, the area of ​​the first region corresponding to the building is 80 square meters, and the target ratio corresponding to building A is 80%.

[0148] S403: Determine the network performance of the target base station according to the target ratio corresponding to each building in the multiple buildings.

[0149] Optionally, the network coverage performance parameters of the target base station for each of the multiple buildings can be determined by the target ratio corresponding to each of the multiple buildings, and multiple network coverage performance parameters can be obtained, and then the network coverage performance of the target base station can be determined based on the multiple network coverage performance parameters.

[0150] Optionally, an average value of multiple network coverage performance parameters of the target base station may be determined, and then the network coverage performance of the target base station may be determined based on the average value of the multiple network coverage performance parameters.

[0151] Optionally, the network coverage performance of the target base station may be determined based on a magnitude relationship between an average value of a plurality of network coverage performance parameters and a preset threshold.

[0152] Exemplarily, when the average value of multiple network coverage performance parameters is greater than or equal to a preset threshold, it is determined that the network coverage performance of the target base station meets the standard; when the average value of multiple network coverage performance parameters is less than the preset threshold, it is determined that the network coverage performance of the target base station does not meet the standard.

[0153] In an embodiment of the present application, by determining the target ratio corresponding to each building in the target area, the network coverage performance parameters of the target base station for each building are determined, and then based on the network coverage performance parameters of the target base station for each building in the target area, the network coverage performance of the target base station is determined, and the network performance of the target base station for individual buildings in the target area is linked to the network performance of the target base station for the target area, thereby improving the efficiency and accuracy of evaluating the shallow network coverage performance of the target area.

[0154] In one design, Figure 6 As shown, in a network performance evaluation method provided in an embodiment of the present application, the above S403 includes S501-S502:

[0155] S501: Determine the network coverage type corresponding to each building according to a size relationship between a target ratio corresponding to each building and a target threshold value.

[0156] The network coverage type includes at least one of the following: good network coverage, adequate network coverage, and insufficient network coverage.

[0157] Optionally, good network coverage is used to indicate that the target base station has good network coverage of the building, or that the network coverage capability of the target base station has achieved the expected effect; standard network coverage is used to indicate that the target base station's network coverage performance of the building has met the basic requirements, or that the target base station's network coverage has achieved the basic purpose; insufficient network coverage is used to indicate that the target base station's network coverage of the building has not met the basic requirements and cannot meet the normal usage needs of network users in the building.

[0158] Optionally, the magnitude relationship between the target ratio and the preset threshold value may also be understood as a multiple relationship between the target ratio and the preset threshold value.

[0159] Exemplarily, the preset threshold is 25%. When the target ratio is three times or more than the preset threshold, the network coverage type of the building corresponding to the target ratio is determined to be good network coverage; when the target ratio is two times or more than the preset threshold and the target ratio is less than three times the preset threshold, the network coverage type of the building corresponding to the target ratio is determined to be qualified network coverage; when the target ratio is less than two times the preset threshold, the network coverage type of the building corresponding to the target ratio is determined to be insufficient network coverage.

[0160] S502: Determine the network performance of the target base station according to the network coverage type corresponding to each building in the multiple buildings.

[0161] Optionally, the coverage type with the largest number of buildings of the three coverage types may be determined according to the network coverage type corresponding to each building in the multiple buildings, and the coverage type may be determined as the network coverage performance of the target base station.

[0162] For example, there are 70 buildings in the target area, of which 50 have good network coverage, 15 have standard network coverage, and 5 have insufficient network coverage. The network coverage performance of the target base station is determined to be good network coverage.

[0163] In an embodiment of the present application, the network coverage type corresponding to each building is determined by the target ratio corresponding to each building in a plurality of buildings, and then the network performance of the target base station is determined according to the network coverage type corresponding to each building in the target area, thereby improving the accuracy of the network performance evaluation of the target base station.

[0164] In one design, the target threshold includes a first threshold and a second threshold, the first threshold being greater than the second threshold; Figure 7 As shown, in a network performance evaluation method provided in an embodiment of the present application, the above S501 includes S601-S603:

[0165] S601: For any building among a plurality of buildings, when it is determined that a target ratio corresponding to any building is greater than or equal to a first threshold, determine that the network coverage type corresponding to any building is good network coverage.

[0166] S602: For any building among the multiple buildings, when it is determined that the target ratio corresponding to any building is greater than or equal to the second threshold and less than the first threshold, determine that the network coverage type corresponding to any building is network coverage meeting the standard.

[0167] S603: For any building among the multiple buildings, when it is determined that the target ratio corresponding to any building is less than a second threshold, determine that the network coverage type corresponding to any building is insufficient network coverage.

[0168] Optionally, the first threshold and the second threshold can be determined according to different usage requirements or relevant industry standards.

[0169] Exemplarily, the first threshold value may be 40%, and the second threshold value may be 20%. When the target ratio corresponding to the building is 50%, the network coverage type of the building corresponding to the target ratio is determined to be good network coverage; when the target ratio corresponding to the building is 30%, the network coverage type of the building corresponding to the target ratio is determined to be qualified network coverage.

[0170] Optionally, the network coverage type can be changed according to specific evaluation accuracy requirements.

[0171] For example, when a more accurate network performance evaluation result is required, the network coverage type of the building can be divided into excellent network coverage, good network coverage, up-to-standard network coverage, insufficient network coverage, and severely insufficient network coverage according to the size relationship between the target ratio and the preset threshold. When a rough evaluation of the network performance is required or needs to be completed in a shorter time, the network coverage type of the building can be divided into up-to-standard network coverage, substandard network coverage, and other network coverage types according to the size relationship between the target ratio and the preset threshold.

[0172] It should be noted that when adding or deleting the type of network coverage, the target threshold value also needs to be changed.

[0173] For example, when "excellent network coverage" is added to the types of network coverage, a third threshold value needs to be set to determine the buildings with excellent network coverage among the multiple buildings through the third threshold value.

[0174] In an embodiment of the present application, based on the first threshold and the second threshold, the network coverage type corresponding to the building is determined according to the size relationship between the target ratio and the first threshold, and the size relationship between the target ratio and the second threshold, thereby achieving a qualitative evaluation of the network coverage performance of the target base station for each building, so as to meet the needs of multi-dimensional network performance evaluation, and through the network coverage type corresponding to each building, the network performance of the target base station is evaluated, thereby improving the accuracy of the evaluation of the network performance of the target base station.

[0175] In one design, Figure 8 As shown, in a network performance evaluation method provided in an embodiment of the present application, the above S502 includes S701-S703:

[0176] S701: Determine the number of buildings corresponding to each network coverage type according to the network coverage type corresponding to each building among multiple buildings.

[0177] Optionally, the number of buildings corresponding to each network coverage type may be determined based on a size relationship between a target threshold and a target ratio corresponding to each of the multiple buildings.

[0178] Exemplarily, for the number of buildings corresponding to the network coverage type of insufficient network coverage, when, among multiple buildings, the number of buildings corresponding to the target ratio being less than the second threshold is 5, then the number of buildings corresponding to the network coverage type of insufficient network coverage is 5.

[0179] S702: Determine a proportion of buildings corresponding to each network coverage type according to the total number of the multiple buildings and the number of buildings corresponding to each network coverage type.

[0180] Optionally, the proportion of buildings corresponding to each network coverage type can be obtained using Formula 3:

[0181]

[0182] Among them, p k is the proportion of buildings corresponding to network coverage type k, D k is the number of buildings corresponding to network coverage type k, and N is the total number of multiple buildings in the target area.

[0183] For example, for the proportion of buildings with network coverage type corresponding to good network coverage, when the total number of multiple buildings in the target area is 100 and the number of buildings with network coverage type corresponding to good network coverage is 50, the proportion of buildings with network coverage type corresponding to good network coverage is 50%.

[0184] S703: Determine the network performance of the target base station according to the proportion of buildings corresponding to each network coverage type in the multiple buildings.

[0185] Optionally, a first evaluation threshold and a second evaluation threshold may be set. When the proportion of buildings corresponding to the network coverage type meeting the network coverage standard is greater than or equal to the first evaluation threshold, and the proportion of buildings corresponding to the network coverage type insufficient network coverage is less than the second evaluation threshold, it is determined that the network performance of the target base station meets the requirements; when the proportion of buildings corresponding to the network coverage type meeting the network coverage standard is less than the first evaluation threshold, or the proportion of buildings corresponding to the network coverage type insufficient network coverage is greater than or equal to the second evaluation threshold, it is determined that the network performance of the target base station does not meet the requirements.

[0186] Optionally, when the network performance of the target base station does not meet the requirements, it is necessary to adjust and optimize the relevant parameters of the target base station and re-evaluate.
