[0038] With the continuous maturity of the fifth-generation mobile communication technology (5G) and the acceleration of the commercialization process, 5G networks are gradually becoming the mainstream in the field of mobile communication with their characteristics of high speed, low latency, and multi-connection. Users are constantly migrating from the fourth-generation mobile communication technology (4G) network to the 5G network, and the traffic load of the 4G network is gradually decreasing. In the context of co-construction and sharing by operators, removing redundant networks and integrating them into the grid helps reduce network operation costs, improve network operation efficiency, and optimize network resource allocation. However, ensuring network performance while removing redundant base stations is a major challenge.

[0039] Currently, redundant base stations are usually removed based on a rough judgment of the engineering parameters of the base stations (such as station spacing and load). However, this method is difficult to evaluate the network performance after the removal of the base stations, and due to the high maintenance requirements of the engineering parameters, it is difficult to ensure their accuracy and effectiveness, resulting in a low accuracy in determining redundant base stations. In addition, with the continuous improvement of the digital level, network planning, construction, maintenance, etc. are becoming increasingly refined, and it is necessary to more accurately determine redundant base stations.

[0040] In view of this, the embodiments of the present application provide a method for determining redundant base stations, which includes: obtaining the measurement report data of the target base station and the measurement report data of the reference base station, respectively determining the effective coverage area of the target base station and the effective coverage area of the reference base station based on the measurement report data of the target base station and the measurement report data of the reference base station, and determining whether the target base station is a redundant base station based on the area of the overlapping area between the effective coverage area of the target base station and the effective coverage area of the reference base station and the capacity of the reference base station after undertaking the services of the target base station.

[0041] That is to say, the method for determining redundant base stations provided by the embodiments of the present application evaluates the target base station based on the area of the overlapping area between the effective coverage area of the target base station and the effective coverage area of the reference base station and the capacity of the reference base station after undertaking the services of the target base station, and determines whether the target base station is a redundant base station. This takes into account the signal coverage range and capacity of the base station, and improves the accuracy of determining redundant base stations compared with the rough evaluation based on the engineering parameters of the target base station in the prior art.

[0042] Exemplarily, Figure 1 is a schematic diagram of the composition of a redundant base station determination device 10 provided by the embodiments of the present application. As Figure 1 shown, the redundant base station determination device 10 may include a processor 101 and a bus 102.

[0049] It should be noted that the memory 104 can exist independently of the processor 101 or be integrated with the processor 101. The memory 104 can be used to store instructions, program codes, or some data, etc. The memory 104 can be located inside the redundant base station determination device 10 or outside the redundant base station determination device 10, without limitation.

[0056] The method for determining a redundant base station provided by the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0057] As Figure 2 shown, the embodiments of the present application propose a method for determining a redundant base station, and the method includes:

[0058] S201. Obtain the measurement report data of the target base station and the measurement report data of the reference base station.

[0059] Among them, the signal coverage area of the reference base station overlaps with the signal coverage area of the target base station.

[0060] In a possible implementation manner, the measurement report (MR) data of the target base station is obtained through the network management center platform to which the target base station belongs, and the MR data of the reference base station is obtained through the network management center platform to which the reference base station belongs.

[0061] It should be noted that mobile devices such as mobile phones will measure the wireless environment where they are located at a preset period to obtain MR data and report it to the base station. After receiving the MR data, the base station transmits the MR data to the network management center platform.

[0062] It should be noted that the number of reference base stations can be one or more. The reference base stations include all base stations whose signal coverage areas overlap with the signal coverage area of the target base station.

[0063] Exemplarily, Figure 3 is a schematic diagram of the signal coverage areas of the target base station and the reference base stations. As Figure 3 shown, it shows the signal coverage area of the target base station T, the signal coverage area of the reference base station R1, the signal coverage area of the reference base station R2, and the signal coverage area of the reference base station R3.

[0064] S202. Determine the effective coverage area of the target base station based on the measurement report data of the target base station, and determine the effective coverage area of the reference base station based on the measurement report data of the reference base station.

[0065] The implementation manner of determining the effective coverage area of the target base station based on the measurement report data of the target base station may be as follows: According to the measurement report data of the target base station, multiple reference signal received powers (RSRPs) and the location information corresponding to each RSRP are obtained. The multiple RSRPs of the target base station are rasterized according to the location information corresponding to each RSRP, and the strong signal ratio of each grid is calculated. The grids with a strong signal ratio greater than a preset ratio (for example, 90%) are used as the effective coverage grids of the target base station, and the area corresponding to the effective coverage grids of the target base station is used as the effective coverage area of the target base station. Among them, the strong signal ratio is the ratio between the number of RSRPs greater than the preset power and the total number of RSRPs.

[0066] Exemplarily, the above-mentioned preset power may be -110 dBm. Of course, the above is only an exemplary description of the preset power, and the above-mentioned preset power may also be other values, for example, -100 dBm, and the embodiments of the present application do not limit this.

[0067] Exemplarily, if grid A is an effective coverage grid of the base station, then grid A satisfies the following formula 1.

[0068]

[0069] Where N i represents the number of RSRPs of base station S in grid A that are greater than -110 dBm. M i represents the total number of RSRPs of base station S in grid A.

[0070] Furthermore, determining the effective coverage area of the reference base station based on the measurement report data of the reference base station may adopt the same method as the above-mentioned target base station.

[0071] Exemplarily, Figure 4 is a schematic diagram of the effective coverage grid of the base station. As Figure 4 shown, grids 2 to 7, grids 10 to 15, grids 18 to 23, grids 26 to 31, grids 34 to 39, grids 42 to 47, and grids 50 to 55 are the effective coverage grids of the base station.

[0072] S203. Determine whether the target base station is a redundant base station based on the area of the overlapping area between the effective coverage area of the target base station and the effective coverage area of the reference base station and the capacity of the reference base station after undertaking the services of the target base station.

[0073] In a possible implementation, it is determined whether the target base station is a redundant base station according to the number of overlapping grids between the effective coverage grids of the target base station and the reference base station, and the capacity of the reference base station after undertaking the services of the target base station. Specifically, reference may be made to the Figure 6 described embodiments, which will not be elaborated here.

[0074] In the redundant base station determination method provided in this application, measurement report data of the target base station and measurement report data of the reference base station are obtained. Based on the measurement report data of the target base station and the measurement report data of the reference base station, the effective coverage area of the target base station and the effective coverage area of the reference base station are respectively determined. And based on the area of the overlapping area between the effective coverage area of the target base station and the effective coverage area of the reference base station, and the capacity of the reference base station after undertaking the services of the target base station, it is determined whether the target base station is a redundant base station.

[0075] That is to say, the redundant base station determination method provided in the embodiments of this application evaluates the target base station according to the area of the overlapping area between the effective coverage area of the target base station and the effective coverage area of the reference base station, and the capacity of the reference base station after undertaking the services of the target base station, and determines whether the target base station is a redundant base station. In this way, the signal coverage range of the base station and the capacity of the base station are considered. Compared with the general technology that roughly evaluates whether the target base station is a redundant base station according to the engineering parameters of the target base station, the accuracy of determining the redundant base station is improved.

[0076] Further, before S203, the capacity of the reference base station after undertaking the services of the target base station can be determined, so as to be able to judge whether the target base station is a redundant base station according to the capacity of the reference base station after undertaking the services of the target base station. In view of this, as Figure 5 shown, the redundant base station determination method described in the embodiments of this application may further include the following steps.

[0077] S501. Obtain the total service data volume of the target base station and the total service data volume of the reference base station.

[0078] In a possible implementation, the daily average traffic of the target base station is obtained, and the daily average traffic of the target base station is used as the total service data volume of the target base station. The daily average traffic of the reference base station is obtained, and the daily average traffic of the reference base station is used as the total service data volume of the reference base station.

[0079] Exemplarily, Table 1 gives the daily average traffic data of the target base station and the reference base station. As shown in Table 1 below, the daily average traffic of the target base station T is 313.4 gigabytes (GB), the daily average traffic of the reference base station R1 is 404.5 GB, the daily average traffic of the reference base station R2 is 383.5 GB, and the daily average traffic of the reference base station R3 is 489.8 GB.

[0081] Base Station Average Daily Traffic (GB) T 313.4 <![CDATA[R1]]> 404.5 <![CDATA[R2]]> 383.5 <![CDATA[R3]]> 489.8

[0082] S502. Determine the capacity of the reference base station after undertaking the services of the target base station based on the total service data volume of the target base station and the total service data volume of the reference base station.

[0083] In a possible implementation, for each reference base station, determine the service proportion of the reference base station undertaking the services of the target base station, and determine the capacity of the reference base station after undertaking the services of the target base station according to the service proportion.

[0084] Optionally, the above service proportion may be the ratio between the first quantity and the second quantity. Wherein, the first quantity is the number of RSRP of the target base station measured in the overlapping area. The second quantity is the number of RSRP of the target base station measured in the effective coverage area of the target base station. The service proportion can be obtained according to the following formula 2.

[0086] Wherein, T represents the target base station, and R i represents the reference base station. represents the base station R i The service proportion of undertaking the services of the target base station. represents the overlapping area between the effective coverage area of the target base station and the effective coverage area of the reference base station R i . Ω T represents the effective coverage area of the target base station.

[0087] Furthermore, the total service data volume of the reference base station after undertaking the services of the target base station can be determined according to the service proportion. The total service data volume of the reference base station after undertaking the services of the target base station can be obtained according to the following formula 3.

[0088]

[0089] Wherein, represents the total service data volume of the reference base station R i after undertaking the services of the target base station. represents the total service data volume of the reference base station R i before undertaking the services of the target base station. represents the base station R i The service proportion of undertaking the services of the target base station. W T represents the total service data volume of the target base station T.

[0090] Optionally, after determining the total service data volume of the reference base station after undertaking the services of the target base station, the total service data volume may be used as the capacity of the reference base station, and the traffic per unit bandwidth of the reference base station after undertaking the services of the target base station may also be calculated based on the total service data volume, and the traffic per unit bandwidth may be used as the capacity of the reference base station. The traffic per unit bandwidth of the reference base station may be obtained according to the following formula 4.

[0092] Wherein, represents the traffic per unit bandwidth of the reference base station R i after undertaking the services of the target base station. represents the total service data volume of the reference base station R i after undertaking the services of the target base station. represents the total bandwidth of the reference base station R i .

[0093] In one embodiment, as Figure 6 shown, the above S203 may be specifically determined by the following S601.

[0094] S601. When the target base station and the reference base station meet the preset conditions, determine that the target base station is a redundant base station.

[0095] Wherein, the preset conditions may include the following condition 1 and condition 2.

[0096] Condition 1: The ratio of the area of the overlapping area between the effective coverage area of the target base station and the effective coverage area of the reference base station to the area of the effective coverage area of the target base station is greater than the first threshold.

[0097] Condition 2: The capacity of the reference base station after undertaking the services of the target base station is less than the second threshold.

[0098] Optionally, the above condition 1 may specifically be: The ratio of the number of grids in the intersection of the effective coverage grids of the target base station and the effective coverage grids of the reference base station to the number of grids in the effective coverage grids of the target base station is greater than the first threshold.

[0099] Exemplarily, the above first threshold may be 90%. Of course, the above is only an exemplary description of the first threshold, and the above first threshold may also be other values, which are not limited in the embodiments of the present application.

[0100] Further, when the first threshold is 90%, the above condition 1 may be expressed as the following formula 5.

[0101]

[0102] Wherein, Ω T ∩ΩR represents the intersection of the effective coverage grid of the target base station T and the effective coverage grid of the reference base station R. card(Ω T ∩Ω R ) represents the number of grids in the intersection of the effective coverage grid of the target base station T and the effective coverage grid of the reference base station R. Ω T represents the effective coverage grid of the target base station T. card(Ω T ) represents the number of grids in the effective coverage grid of the target base station T.

[0103] Exemplarily, Figure 7 is a schematic diagram of the effective coverage grids of the target base station and the reference base station. As Figure 7 shown, the effective coverage grid Ω T of the target base station T can be determined as {23, 24, 25, 26, 27, 33, 34, 35, 36, 37, 43, 44, 45, 46, 47, 48, 53, 54, 55, 56, 57, 63, 64, 65, 66, 67}. The intersection Ω R1 ∩Ω T of the effective coverage grid of the target base station T and the effective coverage grid of the reference base station R1 is {23, 24, 25, 33, 34, 35, 43, 44}. The intersection Ω R2 ∩Ω T of the effective coverage grid of the target base station T and the effective coverage grid of the reference base station R2 is {26, 27, 36, 37, 46, 47, 48, 57}. The intersection Ω R3 ∩Ω T of the effective coverage grid of the target base station T and the effective coverage grid of the reference base station R3 is {53, 54, 55, 56, 63, 64, 65, 66}.

[0104] According to Figure 7 the example, card(Ω1) = 26, Ω T ∩Ω R = {23, 24, 25, 26, 27, 33, 34, 35, 36, 37, 43, 44, 46, 47, 48, 53, 54, 55, 56, 57, 63, 64, 65, 66}, card(Ω T ∩Ω R ) = 24, and further, the ratio between the number of grids in the intersection of the effective coverage grids of the target base station and the reference base station and the number of grids in the effective coverage grid of the target base station can be calculated to satisfy Condition 1.

[0105] It can be understood that when Condition 1 is satisfied, the network coverage range after the target base station T is removed can be borne by the reference base station R, thus ensuring the coverage range after the base station is removed.

[0106] Optionally, the above condition 2 can specifically be that the traffic per unit bandwidth of all reference base stations after undertaking the services of the target base station is less than a second threshold. Condition 2 can be expressed by the following formula 6.

[0107]

[0108] Among them, represents the traffic per unit bandwidth of the reference base station R i after undertaking the services of the target base station. G represents the second threshold.

[0109] Exemplarily, the above second threshold can be 10 GB / MHz. Of course, the above is only an exemplary illustration of the second threshold, and the above second threshold can also be other values, which are not limited in the embodiments of the present application.

[0110] It should be noted that the above second threshold can be adjusted according to the network level, service conditions, etc. in different regions to ensure the accuracy of redundant base station determination.

[0111] Exemplarily, Table 2 gives the number of RSRP of the target base station T in different regions. As shown in Table 2, the number of RSRP of the target base station T in Ω R1 ∩Ω T is 43947, the number of RSRP of the target base station T in Ω R2 ∩Ω T is 32984, the number of RSRP of the target base station T in Ω R3 ∩Ω T is 28934, and the number of RSRP of the target base station T in Ω T is 105865.

[0112] Table 2

[0113]

[0114] Furthermore, if the total bandwidths of the reference base stations R1, R2, and R3 are all 60 megahertz (MHz), then the traffic per unit bandwidth of the reference base stations R1, R2, and R3 after undertaking the services of the target base station can be obtained according to the above formulas 2, 3, and 4 as 8.91 GB / MHz, 8.01 GB / MHz, and 9.59 GB / MHz respectively. The maximum value 9.59 GB / MHz < 10 GB / MHz, satisfying Condition 2.

[0115] It can be understood that when Condition 2 is satisfied, the service data volume after the target base station T is removed can be borne by the reference base station R, which can ensure the capacity requirement after the base station is removed.

[0116] It can be understood that when both Condition 1 and Condition 2 are satisfied, it indicates that both the network coverage range and the service data volume after the target base station T is removed can be borne by the reference base station R. This can ensure that the impact on users after the target base station is removed is relatively small, thereby improving the accuracy of determining redundant base stations.
