In order to speed up network construction, improve network coverage, reduce network construction costs and improve network construction efficiency, operators have begun to explore the model of co-construction and sharing. Co-construction and sharing not only helps to reduce repeated investment, but also improve resource utilization, realize resource sharing and complementary advantages. Since redundant network dismantling and site integration are important means to achieve network co-construction and sharing and maximize network benefits, determining redundant base stations from numerous base stations is a technical problem to be solved at present.

[0003] At present, the traditional method is to roughly judge the engineering parameters of the base station (for example, station distance and load, etc.), and determine the target base station with low load and close to the reference base station as a redundant base station.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0038] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0039] With the development of mobile communication technology, the cost of network construction is getting higher and higher. In order to speed up network construction, improve network coverage, reduce network construction costs and improve network construction efficiency, operators have begun to explore the model of co-construction and sharing. Co-construction and sharing not only helps to reduce repeated investment, but also improves resource utilization, realizes resource sharing and complementary advantages. Since redundant network removal and site integration are important means to achieve network co-construction and sharing and maximize network benefits, it is a technical problem to be solved at present to determine redundant base stations from a large number of base stations so that the signal coverage level after the removal of redundant base stations can meet user needs.

[0040] At present, the traditional method is to roughly judge the engineering parameters of the base station (for example, station distance and load, etc.), and determine the target base station with low load and close to the reference base station as a redundant base station.

[0041] Furthermore, the redundancy of the target base station may be calculated through the measurement report of the target base station, and whether the target base station is a redundant base station may be determined according to a preset redundancy threshold.

[0042] However, the accuracy of determining redundant base stations by the above method is low, and the signal coverage level after the redundant base stations are removed cannot be guaranteed. In addition, the maintenance requirements of the engineering parameters of the base stations are high.

[0043] In view of this, an embodiment of the present application provides a redundant base station determination method, in which a network management device determines an effective coverage area in a signal coverage area of ​​a target base station and an effective coverage area in a signal coverage area of ​​a reference base station of the target base station, and determines whether the target base station is a redundant base station based on the area of ​​an overlapping area between the effective coverage area of ​​the target base station and the effective coverage area of ​​the reference base station and the signal strength. In other words, the redundant base station determination method recorded in the embodiment of the present application is to evaluate the target base station based on the area of ​​an overlapping area between the effective coverage area of ​​the target base station and the effective coverage area of ​​the reference base station and the signal strength to determine whether the target base station is a redundant base station, which takes into account the signal coverage range of the base station and the signal strength of the base station, and improves the accuracy of determining redundant base stations compared to the general technology of roughly evaluating the engineering parameters of the target base station to determine whether the target base station is a redundant base station.

[0044] For example, Figure 1 2 shows a schematic diagram of a redundant base station determination system 10 provided in an embodiment of the present application. The redundant base station determination system 10 may include at least one network management device 101. Figure 1 Only one network management device 101 is shown. The embodiment of the present application does not impose any restriction on the number of network management devices 101.

[0045] The network management device 101 is used to determine the effective coverage area in the signal coverage area of ​​the target base station and the effective coverage area in the signal coverage area of ​​the reference base station of the target base station, and 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 signal strength.

[0046] Optionally, the network management device 101 may be a key device responsible for managing and controlling the communication network. The network management device 101 may receive measurement data from each base station and perform further processing and analysis.

[0047] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of nodes included in the Figure 1 In addition to the functional nodes shown, the redundant base station determination system 10 may also include other nodes, such as terminal equipment, for measuring the signal strength of the base station, and the present application does not impose any limitation on this.

[0061] In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0064] like Figure 3 As shown, an embodiment of the present application proposes a redundant base station determination method, the method comprising:

[0065] S301. A network management device determines an effective coverage area in a signal coverage area of ​​a target base station and an effective coverage area in a signal coverage area of ​​a reference base station of the target base station.

[0066] The signal coverage area of ​​the reference base station overlaps with the signal coverage area of ​​the target base station, and the signal strength in the effective coverage area is greater than the first preset strength.

[0067] Optionally, the implementation process of the above S301 may be: the network management device obtains multiple signal strength values ​​of the target base station and the location information corresponding to each signal strength value, performs rasterization processing on the multiple signal strength values ​​of the target base station according to the location information corresponding to each signal strength value, and calculates the average value of the multiple signal strength values ​​in each grid. The network management device uses the grid whose average value of the multiple signal strength values ​​is greater than the first preset strength as the effective coverage grid of the target base station, and uses the area corresponding to the effective coverage grid of the target base station as the effective coverage area in the signal coverage area of ​​the target base station. Similarly, the network management device can determine the effective coverage area in the signal coverage area of ​​the reference base station by the same method as the above-mentioned target base station.

[0068] Exemplarily, the signal strength may be a reference signal receiving power (RSRP). Of course, the above is only an exemplary description of the signal strength, and the signal strength may also be other data, such as a received signal strength indicator (RSSI), and the present application embodiment does not impose any limitation on this.

[0069] Exemplarily, the first preset intensity may be -110 dBm. Of course, the above is only an exemplary description of the first preset intensity, and the first preset intensity may also be other intensities, such as -105 dBm, and the present application embodiment does not impose any limitation on this.

[0070] It should be noted that the number of reference base stations can be one or more. The reference base station and the target base station belong to different communication operators, that is, the reference base station is a base station in the existing network base station of the other operator whose signal coverage area overlaps with that of the target base station. The redundant base station determination method provided in the embodiment of the present application involves the site addresses of the base stations of both operators. It is not a simple one-to-one determination of co-location and near-location to determine redundant base stations, but rather a determination of the target base station and all base stations of the other operator whose signal coverage areas overlap with those of the target base station.

[0071] For example, Figure 4 is a schematic diagram of the overlapping area of ​​the signal coverage area of ​​the target base station and the reference base station. Figure 4 As shown, the signal coverage areas of the target base station and the reference base station and the overlapping areas of the signal coverage areas of the target base station and the reference base station are shown.

[0072] Exemplarily, Table 1 gives an exemplary description of multiple signal strength values ​​of the target base station. As shown in Table 1 below, the target base station is numbered 1, and an RSRP measurement value of the target base station in a grid numbered 1 is -118dBm. An RSRP measurement value of the target base station in a grid numbered 3 is -122dBm. An RSRP measurement value of the target base station in a grid numbered 10 is -88dBm. An RSRP measurement value of the target base station in a grid numbered 13 is -84dBm. An RSRP measurement value of the target base station in a grid numbered 15 is -85dBm. An RSRP measurement value of the target base station in a grid numbered 21 is -90dBm.

[0073] Of course, the above is only an exemplary description of multiple signal strength values ​​of the target base station. The multiple signal strength values ​​of the target base station may also be other values, and the embodiments of the present application do not impose any limitation on this.

[0074] Table 1

[0075] Base station number Grid number RSRP(dBm) 1 1 -118 1 3 -122 1 10 -88 1 13 -84 1 15 -85 1 21 -90 ... ... ...

[0076] Exemplarily, Table 2 gives an exemplary description of multiple signal strength values ​​of the reference base station. As shown in Table 2 below, an RSRP measurement value of the reference base station numbered D1 in the grid numbered 7 is -78dBm. An RSRP measurement value of the reference base station numbered D1 in the grid numbered 8 is -97dBm. An RSRP measurement value of the reference base station numbered D1 in the grid numbered 9 is -88dBm. An RSRP measurement value of the reference base station numbered D2 in the grid numbered 14 is -84dBm. An RSRP measurement value of the reference base station numbered D2 in the grid numbered 15 is -83dBm. An RSRP measurement value of the reference base station numbered D2 in the grid numbered 16 is -96dBm.

[0077] Of course, the above is only an exemplary description of multiple signal strength values ​​of the reference base station. The multiple signal strength values ​​of the reference base station can also be other values, and the embodiments of the present application do not impose any limitation on this.

[0080] For example, Figure 5 is a schematic diagram of the effective coverage grid of the target base station and the reference base station. Figure 5 As shown, the set of effective coverage grids of the target base stations is Ω1 = {8, 9, 10, 11, 14, 15, 16, 17, 20, 21, 22, 23, 26, 27, 28, 29}, and the set of effective coverage grids of the reference base stations is Ω2 = {2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 20, 21, 22, 23, 25, 26, 27, 28, 32, 33}.

[0081] S302: The network management device determines whether the target base station is a redundant 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 signal strength.

[0082] The redundant base station may refer to a base station that can be removed.

[0083] Optionally, the implementation process of the above S302 may be: the network management device determines whether the target base station is a redundant base station according to the number of overlapping grids between the effective coverage grid of the target base station and the effective coverage grid of the reference base station and the difference between the signal strengths of the target base station and the reference base station in the overlapping grids. Figure 7 The described embodiments are not described in detail here.

[0084] In the redundant base station determination method provided by the present application, the network management device determines the effective coverage area in the signal coverage area of ​​the target base station and the effective coverage area in the signal coverage area of ​​the reference base station of the target base station, and determines whether the target base station is a redundant base station based on the area of ​​the overlapping area of ​​the effective coverage area of ​​the target base station and the effective coverage area of ​​the reference base station and the signal strength. In other words, the redundant base station determination method recorded in the embodiment of the present application is to evaluate the target base station based on the area of ​​the overlapping area of ​​the effective coverage area of ​​the target base station and the effective coverage area of ​​the reference base station and the signal strength to determine whether the target base station is a redundant base station, which takes into account the signal coverage range of the base station and the signal strength of the base station, and improves the accuracy of determining redundant base stations compared to the general technology of roughly evaluating the engineering parameters of the target base station to determine whether the target base station is a redundant base station.

[0085] In one possible implementation, Figure 6 As shown, the above S301 can be specifically determined through the following S601 to S602.

[0086] S601: A network management apparatus obtains a plurality of signal strength values ​​of each of a plurality of sub-areas in a signal coverage area of ​​a target base station and a plurality of signal strength values ​​of each of a plurality of sub-areas in a signal coverage area of ​​a reference base station.

[0087] Optionally, the implementation process of the above S601 may be: the network management device sends a request message to a user device that has a connection relationship with the target base station, wherein the request message is used to instruct the user device to collect the signal strength data of the target base station. Accordingly, the user device receives the request message from the network management device, and measures the signal of the target base station to obtain the signal strength value of the target base station. The user device sends the signal strength value of the target base station and the longitude and latitude information of the user device to the network management device. Accordingly, the network management device receives the signal strength value of the target base station and the longitude and latitude information of the user device from the user device. The network management device divides the signal coverage area of ​​the target base station into multiple sub-areas, and divides the multiple signal strength values ​​of the target base station into corresponding sub-areas according to the longitude and latitude information of the user device, and obtains multiple signal strength values ​​of each sub-area in the multiple sub-areas of the signal coverage area of ​​the target base station. Similarly, the network management device can obtain multiple signal strength values ​​of each sub-area in the multiple sub-areas of the signal coverage area of ​​the reference base station in the same method as the above-mentioned target base station.

[0088] S602: The network management device uses the first sub-area among the multiple sub-areas of the target base station as the effective coverage area of ​​the target base station, and uses the first sub-area among the multiple sub-areas of the reference base station as the effective coverage area of ​​the reference base station.

[0089] The average value of the multiple signal strength values ​​in the first sub-area is greater than the first preset strength.

[0090] Optionally, the implementation process of the above S602 may be: the network management device calculates the average value of multiple signal strength values ​​of each sub-area in the multiple sub-areas of the target base station, and takes the sub-area whose average value of the multiple signal strength values ​​is greater than the first preset strength as the effective coverage area of ​​the target base station. Similarly, the network management device may determine the effective coverage area of ​​the reference base station in the same manner as the above target base station.

[0091] It can be understood that the above-mentioned first preset strength can be understood by referring to the relevant description of the first preset strength in the above-mentioned S301, and will not be repeated here.

[0092] Optionally, the first sub-region may satisfy the following formula 1.

[0093]

[0094] Where M is the number of multiple signal strength values ​​of the base station in the first sub-area, RSRP i,n is the nth signal strength value, i is the number of the base station, and a is the first preset strength.

[0095] In one possible implementation, Figure 7 As shown, the above S302 can be specifically determined by the following S701.

[0096] S701. When the area ratio between the overlapping area of ​​the effective coverage area of ​​the target base station and the effective coverage area of ​​the reference base station and the effective coverage area of ​​the target base station is greater than a first threshold, and the difference between the signal strength of the target base station and the signal strength of the reference base station in the overlapping area is less than a second threshold, and the difference between the strong coverage range of the target base station and the strong coverage range of the reference base station is less than a third threshold, the network management device determines that the target base station is a redundant base station.

[0097] The signal strength within the strong coverage area is greater than a second preset strength, and the second preset strength is greater than the first preset strength.

[0098] The above S701 can be divided into the following three conditions:

[0099] Condition 1: an area ratio between an overlapping area of ​​an effective coverage area of ​​the target base station and an effective coverage area of ​​the reference base station and the effective coverage area of ​​the target base station is greater than a first threshold.

[0100] Optionally, the above condition 1 may specifically be: a ratio between the number of grids in the intersection of the effective coverage grid of the target base station and the effective coverage grid of the reference base station and the number of effective coverage grids of the target base station is greater than a first threshold.

[0101] Exemplarily, the first threshold may be 90%. Of course, the above is only an exemplary description of the first threshold, and the first threshold may also be other values, which is not limited in any way in the embodiments of the present application.

[0102] Combined with the above example, the set of effective coverage grids of the target base station is Ω1 = {8, 9, 10, 11, 14, 15, 16, 17, 20, 21, 22, 23, 26, 27, 28, 29}, card(Ω1) = 16, and the set of effective coverage grids of the reference base station is Ω2 = {2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29}. 32,33}, card(Ω2)=25, then the intersection of the effective coverage grid of the target base station and the effective coverage grid of the reference base station is Ω1∩Ω2={8,9,10,11,14,15,16,17,20,21,22,23,26,27,28}, card(Ω1∩Ω2)=15, the ratio of the number of grids in the intersection of the effective coverage grid of the target base station and the effective coverage grid of the reference base station to the number of effective coverage grids of the target base station is Among them, card(Ω i ) is the set Ω i The number of elements in . Condition 1 is met.

[0103] Condition 2: The difference between the signal strength of the target base station and the signal strength of the reference base station in the overlapping area is less than the second threshold.

[0104] Optionally, the above condition 2 may specifically be: the difference between the average signal strength values ​​of multiple signals of the target base station in the overlapping area and the average signal strength values ​​of multiple signals of the reference base station is less than a second threshold, which can be expressed by the following formula 2.

[0105]

[0106] Among them, S i It is the total number of signal strength values ​​of multiple signals of the target base station in the overlapping area, RSRP i,n is the signal strength value of the nth signal of the target base station in the overlapping area, S j It is the total number of signal strength values ​​of multiple signals of the reference base station in the overlapping area, RSRPj,n is the signal strength value of the nth signal of the reference base station in the overlapping area, and b is the second threshold.

[0107] Exemplarily, the second threshold may be 0.4 dBm. Of course, the above is only an exemplary description of the second threshold, and the second threshold may also be other values, which is not limited in any way in the embodiments of the present application.

[0108] Exemplarily, the average value of the signal strength values ​​of the multiple signals of the target base station in the overlapping area is -92.6dBm, and the average value of the signal strength values ​​of the multiple signals of the reference base station in the overlapping area is -92.8dBm. Then, the difference between the average value of the signal strength values ​​of the multiple signals of the target base station in the overlapping area and the average value of the signal strength values ​​of the multiple signals of the reference base station is -92.6dBm-(-92.8dBm)=0.2dBm. 0.2dBm is less than 0.4dBm, which satisfies condition 2.

[0109] Condition 3: The difference between the strong coverage range of the target base station and the strong coverage range of the reference base station in the overlapping area is less than a third threshold.

[0110] Optionally, the above condition 3 may specifically be: the difference between the high level sampling ratio of the target base station and the high level sampling ratio of the reference base station in the overlapping area is less than a third threshold, which can be expressed by the following formula 3.

[0111]

[0112] Among them, ∑ m RSRP i,m (Q1∩Ω2>-95dBm) is the number of signal strength values ​​greater than -95dBm (i.e., the second preset strength) among the multiple signal strength values ​​of the target base station in the overlapping area, S i is the total number of multiple signal strength values ​​of the target base station in the overlapping area, ∑ n RSRP i,n (Ω1∩Ω2>-95dBm) is the number of signal strength values ​​greater than -95dBm among the multiple signal strength values ​​of the reference base station in the overlapping area, S j is the total number of multiple signal strength values ​​of the reference base station in the overlapping area, and c is the third threshold.

[0113] Exemplarily, the third threshold may be 0.6%. Of course, the above is only an exemplary description of the third threshold, and the third threshold may also be other values, which is not limited in any way in the embodiments of the present application.

[0114] Exemplarily, the high level sampling ratio of the target base station in the overlapping area is 77%, and the high level sampling ratio of the reference base station in the overlapping area is 78%, then the difference between the high level sampling ratio of the target base station and the high level sampling ratio of the reference base station in the overlapping area is 77%-78%=-1%. -1% is less than 0.6%, which satisfies condition 3.

[0115] Optionally, the above condition 3 can be specifically: the difference between the average value of the signal strength values ​​of multiple first signals of the target base station and the average value of the signal strength values ​​of multiple first signals of the reference base station is less than a third threshold; wherein the signal strength value of the first signal is greater than the second preset strength.

[0116] When the above three conditions are all met, the network management device determines that the target base station is a redundant base station.

[0117] It should be noted that the values ​​of the first threshold, the second threshold, the third threshold, and the second preset strength can be adjusted based on network planning data, historical statistical information, and network conditions in different areas and scenarios to ensure the accuracy and adaptability of redundant base station determination.

[0118] It can be understood that the area ratio between the overlapping area of ​​the effective coverage area of ​​the target base station and the effective coverage area of ​​the reference base station and the effective coverage area of ​​the target base station is greater than the first threshold, which means that the overlapping area between the effective coverage area of ​​the reference base station and the effective coverage area of ​​the target base station is large, which can ensure that the signal coverage range of the target base station is basically unaffected after the demolition. The difference between the signal strength of the target base station and the signal strength of the reference base station in the overlapping area is less than the second threshold, which means that the difference between the signal strength of the target base station and the signal strength of the reference base station is small, which can ensure that the signal strength of the target base station is basically not reduced after the demolition. The difference between the strong coverage range of the target base station and the strong coverage range of the reference base station in the overlapping area is less than the third threshold, which means that the difference between the strong coverage range of the target base station and the strong coverage range of the reference base station is small, which can ensure that the strong coverage level of the signal is basically unchanged after the demolition of the target base station.

[0119] That is to say, when the area ratio between the overlapping area of ​​the effective coverage area of ​​the target base station and the effective coverage area of ​​the reference base station and the effective coverage area of ​​the target base station is greater than the first threshold, and the difference between the signal strength of the target base station and the signal strength of the reference base station in the overlapping area is less than the second threshold, and the difference between the strong coverage range of the target base station and the strong coverage range of the reference base station is less than the third threshold, the role of the target base station can be replaced by the reference base station, which can ensure that after the target base station is demolished, the signal coverage level will not weaken for the users of the demolishing operator, thereby reducing the risk of base station demolition.

[0120] Figure 8An overall flow chart of a redundant base station determination method provided in an embodiment of the present application, such as Figure 8 As shown, the redundant base station determination method provided in the embodiment of the present application may include the following steps.

[0121] S801. A network management device obtains measurement report (MR) data of a target base station and a reference base station, and performs rasterization processing on the MR data.

[0122] Optionally, the MR data includes multiple signal strength values ​​of the target base station and the reference base station and position information corresponding to each signal strength value.

[0123] S802: The network management apparatus determines the effective coverage grid of the target base station and the effective coverage grid of the reference base station based on the MR data after rasterization processing.

[0124] The average value of multiple RSRP measurement values ​​within the effective coverage grid is greater than -110 dBm.

[0125] S803: The network management device determines whether the effective coverage grid ratio is greater than a first threshold.

[0126] Among them, the effective coverage grid ratio is the ratio between the number of elements in the effective coverage grid intersection and the number of elements in the effective coverage grid set of the target base station, and the effective coverage grid intersection is the intersection of the effective coverage grid set of the target base station and the effective coverage grid set of the reference base station.

[0127] If the effective coverage grid ratio is less than or equal to the first threshold, the network management device executes step S804.

[0128] S804: The network management device determines that the target base station is a non-redundant base station.

[0129] If the effective coverage grid ratio is greater than the first threshold, the network management device executes step S805.

[0130] S805: The network management device determines whether the average level difference is less than a second threshold.

[0131] The average level difference is the difference between the average RSRP measurement value of the target base station in the intersection of the effective coverage grids and the average RSRP measurement value of the reference base station in the intersection of the effective coverage grids.

[0132] If the average level difference is greater than or equal to the second threshold, the network management device executes step S804.

[0133] If the average level difference is less than the second threshold, the network management device executes step S806.

[0134] S806: The network management device determines whether the high-level sampling ratio difference is less than a third threshold.

[0135] Among them, the high-level sampling ratio difference is the difference between the high-level sampling ratio of the target base station in the intersection of the effective coverage grid and the high-level sampling ratio of the reference base station in the intersection of the effective coverage grid, and the high-level sampling ratio is the ratio between the number of RSRP measurement values ​​greater than the second preset strength and the total number of RSRP measurement values.

[0136] If the high level sampling ratio difference is greater than or equal to the third threshold, the network management device executes step S804.

[0137] If the high level sampling ratio difference is less than the third threshold, the network management device executes step S807.

[0138] S807: The network management device determines that the target base station is a redundant base station, and outputs the number of the target base station.
