[0002] In a 5G network environment, a terminal device often receives signals from multiple cells (which can be simply understood as areas covered by base stations one by one) simultaneously. When the signals of multiple cells overlap and cover the same place, signal interference may occur, which may trigger signal interference phenomena, thereby affecting the communication quality of users, such as a decrease in Internet access speed, call interruption, etc. To effectively improve the network quality, network optimization engineers need to accurately identify and locate areas with serious overlapping coverage problems in order to take targeted optimization measures.

[0003] However, most of the existing overlapping coverage degree evaluation methods are based on simple level difference threshold judgments, that is, by comparing whether the absolute value of the level difference between the serving cell and adjacent cells is less than a certain set value to determine whether there is overlapping coverage, and the overlapping coverage degree of the serving cell cannot be accurately evaluated.

[0060] Without departing from the spirit or scope of the present application, various modifications and variations can be made in the present application, which will be obvious to those skilled in the art. Therefore, the present application is intended to cover the modifications and variations of the present application that fall within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in the present application can be combined with each other without conflict.

[0061] Before elaborating on the technical solutions provided in the embodiments of the present application, for the convenience of understanding the embodiments of the present application, the present application first specifically describes the problems existing in the related technologies:

[0062] In a 5G network environment, a terminal device often receives signals from multiple cells (which can be simply understood as the areas covered by each base station) simultaneously. When the signals of multiple cells overlap and cover the same place, signal interference may occur, which may trigger a signal interference phenomenon, thereby affecting the communication quality of users, such as a decrease in Internet access speed, call interruption, etc. To effectively improve the network quality, network optimization engineers need to accurately identify and locate the areas with serious overlapping coverage problems in order to take targeted optimization measures.

[0063] However, most of the related overlapping coverage evaluation methods are based on simple level difference threshold judgments, that is, by comparing whether the absolute value of the level difference between the serving cell and the adjacent cell is less than a certain set value to determine whether there is overlapping coverage, and the overlapping coverage of the serving cell cannot be accurately evaluated. For example, when the level of the serving cell is greater than that of the co-frequency neighboring cell, the smaller the absolute value of the level difference, the more serious the interference; when the level of the serving cell is less than that of the co-frequency neighboring cell, the larger the absolute value, the more serious the interference, and the related methods ignore this difference. Therefore, there is a problem in the related technologies that the overlapping coverage of the serving cell cannot be accurately evaluated.

[0064] Based on this, the embodiments of the present application provide a method, apparatus, device, medium, and program product for determining the overlapping coverage, which can accurately evaluate the overlapping coverage of the serving cell.

[0065] The following elaborates in detail on the method for determining the overlapping coverage provided in the embodiments of the present application with reference to the accompanying drawings.

[0066] Figure 1 It is a schematic flowchart of a method for determining the overlapping coverage provided in the embodiments of the present application. As Figure 1 shown, the method may include steps S110 to S140.

[0067] S110. Obtain at least one first service information of a target base station at a first moment. The first service information corresponds one-to-one to a terminal device located within the coverage area of the target base station. The first service information includes a first electrical signal corresponding to the target base station and second electrical signals respectively corresponding to N target adjacent base stations, where N is an integer greater than or equal to 1.

[0068] Among them, the target base station is a base station installed in the serving cell of this service.

[0069] An adjacent base station is a base station installed in another cell adjacent to the serving cell of this service, which may cause interference or influence to the terminal devices within the target base station.

[0070] A terminal device can be uniquely identified by a device identifier. Therefore, the one-to-one correspondence between the first service information and the terminal devices located within the coverage area of the target base station means that the first service information corresponds one-to-one to the device identifier. Thus, the terminal device used by one user corresponds to one first service information, and the terminal devices used by different users correspond to different first service information.

[0071] The first electrical signal is the electrical signal corresponding to the target base station.

[0072] The second electrical signal is the electrical signal corresponding to the target adjacent base station.

[0073] Specifically, obtain the service information of each terminal device within the cell, and use the service information of the same terminal device as a sampling point. Each sampling point includes the information of the first electrical signal corresponding when the terminal device accesses the Internet and the information of multiple second electrical signals.

[0074] Next, in steps S120 - S140, the electrical signal difference corresponding to each sampling point (first service information) can be calculated, and then based on the electrical signal difference corresponding to each sampling point (first service information), the overlapping coverage degree corresponding to the target base station can be determined.

[0075] S120. Determine the total electrical signal corresponding to the first service information according to the N second electrical signals. The total electrical signal is calculated based on a total power value, and the total power value is the sum of the power values respectively corresponding to the N second electrical signals.

[0076] Specifically, when calculating the electrical signal difference corresponding to the sampling point (the first service information), the total electrical signal corresponding to the first service information can be determined first based on N second electrical signals: the N second electrical signals in the sampling point (the first service information) are respectively converted into corresponding actual received power values to obtain N actual received power values, so that the sum operation can be directly performed on all the actual received power values to obtain the total power value, which can reflect the strength of the interference from the target adjacent base station in the operation result (the total power value), and can more accurately measure the impact of the level of the target adjacent cell on the interference of this cell (the serving cell where the target base station is located). Next, the total power value is converted into a total electrical signal, so as to obtain the total electrical signal corresponding to the first service information.

[0077] S130. Subtract the first electrical signal from the total electrical signal to obtain the electrical signal difference corresponding to the first service information.

[0078] Specifically, when calculating the electrical signal difference corresponding to the sampling point (the first service information), the total electrical signal corresponding to the sampling point (the first service information) can be determined first through step S120 based on N second electrical signals, and then the total electrical signal is subtracted from the first electrical signal (the electrical signal corresponding to the target base station) to obtain the electrical signal difference corresponding to the sampling point (the first service information). Alternatively, the electrical signal difference corresponding to the first service information can be obtained by taking the inverse after subtracting the total electrical signal from the first electrical signal. This electrical signal difference can accurately reflect the interference situation under different level relationships, so as to more accurately evaluate the overlapping coverage degree of the serving cell.

[0079] For example, the sum of the N power values in the sampling point (the first service information) is obtained to get the total power value, then the total power value is converted into the total level, and then the level difference between the total level and the level of this serving cell is calculated to measure the severity of the overlapping coverage. The originally two-dimensional data (level difference and the number of adjacent cells) can be converted into one-dimensional data (level difference). The magnitude of the level difference can directly measure the degree of overlapping coverage, which is objective and concise.

[0080] S140. Determine the overlapping coverage degree corresponding to the target base station according to at least one electrical signal difference.

[0081] Specifically, the overlapping coverage degree corresponding to the target base station can be determined according to the electrical signal difference corresponding to each sampling point (the first service information).

[0082] According to the method for determining the overlapping coverage provided by the embodiments of the present application, by obtaining at least one first service information of a target base station in a first time in a serving cell of this application, the first service information corresponds one-to-one to a terminal device located within the coverage area (the serving cell) of the target base station. Each first service information corresponding to a terminal device includes a first electrical signal corresponding to the target base station in the serving cell and second electrical signals respectively corresponding to target neighboring base stations in N target neighboring cells, where N is an integer greater than or equal to 1. Then, calculate the electrical signal difference corresponding to each first service information. Specifically, the N second electrical signals in the first service information can be respectively converted into corresponding actual received power values to obtain N actual received power values. Thus, the sum operation can be directly performed on all the actual received power values to obtain the total power value, which can reflect the strength of the interference from the target neighboring base stations in the operation result (total power value), and can more accurately measure the influence of the target neighboring cell level on the interference of the serving cell (the serving cell where the target base station is located). Next, convert the total power value into a total electrical signal to obtain the total electrical signal corresponding to the first service information, and then subtract the first electrical signal corresponding to the target base station from the total electrical signal, so as to obtain the electrical signal difference corresponding to the first service information. This electrical signal difference can accurately measure the severity of the overlapping coverage. After calculating the electrical signal difference corresponding to each first service information, next, according to the electrical signal differences corresponding to each first service information, accurately measure the overlapping coverage corresponding to the target base station, thereby providing a more scientific and accurate basis for network optimization, helping to improve network quality, reduce interference, and enhance the user experience.

[0083] Figure 2 It is a schematic flowchart of a method for determining the overlapping coverage provided by the embodiments of the present application.

[0084] In some embodiments, as Figure 2 shown, step S120 of determining the total electrical signal corresponding to the first service information according to N second electrical signals may include steps S121 to S123.

[0085] S121, convert the N second electrical signals into power values respectively to obtain N power values.

[0086] For example:

[0087]

[0088] where p is the power value and s is the second electrical signal.

[0089] S122, add the N power values to obtain the total power value corresponding to the first service information.

[0090] S123, determine the total electrical signal corresponding to the first service information according to the total power value.

[0091] For example,

[0092] S 总 = 10 × log P 总

[0093] where S 总 is the total electrical signal, and P 总 is the total power value.

[0094] Specifically, by converting N second electrical signals (electrical signals corresponding to target adjacent base stations) in the sampling points into power values respectively, it can be quantified, which is beneficial to mathematical operations; then adding the N power values to obtain the total power value corresponding to the sampling point, and then the total power value corresponding to the sampling point can be converted back into the total electrical signal corresponding to the sampling point.

[0095] In the embodiment of the present application, by converting the second electrical signals corresponding to N target adjacent base stations in the sampling points into power values respectively, the quantification of the electrical signal is realized, which provides convenience for subsequent mathematical operations; then adding the N power values to obtain the total power value corresponding to the sampling point, and then converting the total power value corresponding to the sampling point into an electrical signal, that is, obtaining the total electrical signal corresponding to the sampling point, so as to more accurately quantify the influence degree of the electrical signals of each target adjacent cell on the serving cell (the serving cell where the target base station is located).

[0096] Figure 3 It is a schematic flowchart of a method for determining the overlapping coverage provided by the embodiment of the present application.

[0097] In some embodiments, as Figure 3 shown, step S140 determines the overlapping coverage corresponding to the target base station according to at least one electrical signal difference, including steps S141 and S142.

[0098] S141, determine the sub - overlapping coverage corresponding to the first service information according to the electrical signal difference.

[0099] S142, add at least one sub - overlapping coverage and then divide by the number of the first service information to obtain the overlapping coverage of the target base station.

[0100] Specifically, the specific process of determining the overlapping coverage of the target base station through the electrical signal differences corresponding to each sampling point is as follows: calculate the overlapping coverage corresponding to the sampling point (the first service information) according to the electrical signal difference corresponding to the sampling point, and this overlapping coverage can be called the sub - overlapping coverage, obtaining a quantitative evaluation of the coverage situation of a single service information; then, after accumulating the sub - overlapping coverages corresponding to all sampling points (the first service information), divide by the total number of sampling points (the first service information), so as to obtain the overall overlapping coverage of the target base station.

[0101] In the embodiments of the present application, by calculating the sub-overlap coverage corresponding to each sampling point, then accumulating the sub-overlap coverages of all sampling points and dividing by the total number of sampling points, the overall overlap coverage of the target base station can be obtained, which can accurately measure the overall overlap coverage of the target base station, provide a scientific and accurate basis for network optimization, help improve network quality, reduce interference, and enhance the user experience.

[0102] Figure 4 It is a schematic flowchart of a method for determining the overlap coverage provided by the embodiments of the present application.

[0103] In some embodiments, as Figure 4 shown, step S141 for determining the sub-overlap coverage corresponding to the first service information according to the electrical signal difference may include steps S1411 and S1412.

[0104] S1411, determine the minimum electrical signal difference and the maximum electrical signal difference among at least one electrical signal difference.

[0105] S1412, determine the sub-overlap coverage corresponding to the first service information according to the electrical signal difference, the minimum electrical signal difference, and the maximum electrical signal difference.

[0106] For example,

[0107]

[0108] where Ci is the sub-overlap coverage corresponding to the first service information, Si is the electrical signal difference corresponding to the first service information, Smax is the maximum electrical signal difference, and Smin is the minimum electrical signal difference.

[0109] Specifically, from the electrical signal differences corresponding to all sampling points, the minimum electrical signal difference Smin and the maximum electrical signal difference Smax can be found. Substituting the minimum electrical signal difference Smin, the maximum electrical signal difference Smax, and the electrical signal difference Si of the sampling point into the above formula, the sub-overlap coverage Ci corresponding to this sampling point can be calculated, and thus the sub-overlap coverages Ci corresponding to each sampling point can be calculated.

[0110] In the embodiments of the present application, by introducing the calculation of the maximum electrical signal difference Smax and the minimum electrical signal difference Smin, the maximum electrical signal difference Smax and the minimum electrical signal difference Smin, as the key boundaries of the electrical signal difference range, not only provide a relative reference for the electrical signal difference Si of each sampling point, but also enable the calculation of the sub-overlap coverage to fully consider the extreme situations of the electrical signal strength, thereby avoiding the deviation that may be brought by a single electrical signal difference and improving the accuracy and reliability of the calculation of the sub-overlap coverage Ci.

[0111] Figure 5It is a schematic flowchart of a method for determining the overlapping coverage provided by an embodiment of the present application.

[0112] In some embodiments, as Figure 5 shown, Si is the normalized difference in electrical signal corresponding to the first service information. Step S1411 of determining the minimum difference in electrical signal and the maximum difference in electrical signal among at least one difference in electrical signal may include steps S14111 and S14112.

[0113] S14111, perform normalization processing on the difference in electrical signal to obtain the normalized difference in electrical signal, and the normalized difference in electrical signal is greater than or equal to 0 and less than or equal to 1.

[0114] S14112, determine the minimum difference in electrical signal and the maximum difference in electrical signal among at least one normalized difference in electrical signal.

[0115] Step S1412 of determining the sub - overlapping coverage corresponding to the first service information according to the difference in electrical signal, the minimum difference in electrical signal, and the maximum difference in electrical signal may include step S14121.

[0116] S14121, determine the sub - overlapping coverage corresponding to the first service information according to the normalized difference in electrical signal, the minimum difference in electrical signal, and the maximum difference in electrical signal.

[0117] Specifically, the differences in electrical signal corresponding to each sampling point may be normalized first, converted into values within a closed range (between 0 and 1), and then the sub - overlapping coverage corresponding to the sampling point is calculated according to the normalized difference in electrical signal. By performing normalization processing on the difference in electrical signal, the difference in electrical signal is restricted within a closed range of 0 to 1, which improves the stability and accuracy of the calculation result.

[0118] Figure 6 It is a schematic flowchart of a method for determining the overlapping coverage provided by an embodiment of the present application.

[0119] In some embodiments, as Figure 6 shown, step S110 of obtaining the first service information of the target base station at the first moment may include steps S111 to S113.

[0120] S111, obtain the service information of the target base station at the first moment. The service information corresponds one - to - one with the terminal devices located within the coverage range of the target base station. The service information includes the second service information and the initial first service information. The second service information includes the first frequency point information corresponding to the target base station and the second frequency point information corresponding to each of the M adjacent base stations respectively. The initial first service information includes the first electrical signal corresponding to the target base station and the second electrical signals corresponding to each of the M adjacent base stations respectively, where M is an integer greater than or equal to 1.

[0121] Among them, the service information of the target base station at the first moment is the measurement data at the first moment reported by the terminal, which can be collected using the existing server. The operator can quickly deploy it without installing or using other devices. Just change the algorithm using the existing server, and the cost is low.

[0122] In one example, the second service information corresponding to the terminal device 1 is shown in Table 1.

[0133] Specifically, first collect the initial first service information and the second service information of the target base station at the first moment. The initial first service information includes the first electrical signal corresponding to the target base station and the second electrical signals corresponding to the M adjacent base stations respectively. The second service information includes the first frequency point information corresponding to the target base station and the second frequency point information corresponding to the M adjacent base stations respectively. Then, according to the second service information, adjacent base stations (target adjacent base stations) with the same frequency as the target base station can be found. Next, the first service information can be obtained: the first electrical signal corresponding to the target base station and the second electrical signals corresponding to the N target adjacent base stations respectively.

[0134] In the embodiment of the present application, the service information of the target base station at the first moment can be collected through the existing server, and then the adjacent base stations with the same frequency as the target base station, that is, the target adjacent base stations, can be accurately screened out, effectively focusing on the key points of analysis, reducing unnecessary calculations, and only calculating the overlapping coverage of the co-frequency neighboring cells (the serving cells where the target adjacent base stations are located). Considering all target adjacent base stations with the same frequency as the target base station in the serving cell of this service, the accuracy and efficiency of the analysis are improved, and there is no need to install or use other devices. Just changing the algorithm of the existing server has low cost.

[0135] In one example, the service information of the target base station at the first moment further includes the serving cell carrier-to-noise ratio. The carrier-to-noise ratio is an important indicator for measuring signal quality. Through the analysis of the inventor, it is found that there is a good linear correlation between the electrical signal difference and the serving cell carrier-to-noise ratio. Therefore, this indicates that the electrical signal difference can be used as an important reference indicator for evaluating the overlapping coverage.

[0136] Based on the same inventive concept, the embodiment of the present application further provides a device for determining the overlapping coverage, as Figure 7 shown. The device 700 may include an acquisition module 710, a determination module 720, and a calculation module 730:

[0137] The acquisition module 710 is configured to acquire at least one piece of service information of the target base station at the first moment. The first service information corresponds one-to-one to the terminal devices within the coverage range of the target base station. The first service information includes the first electrical signal corresponding to the target base station and the second electrical signals respectively corresponding to N target adjacent base stations, where N is an integer greater than or equal to 1;

[0138] The determination module 720 is configured to determine the total electrical signal corresponding to the first service information according to the N second electrical signals. The total electrical signal is calculated based on the total power value, and the total power value is the sum of the power values respectively corresponding to the N second electrical signals;

[0139] The calculation module 730 is configured to subtract the first electrical signal from the total electrical signal to obtain the electrical signal difference corresponding to the first service information;

[0140] The determination module 720 is further configured to determine the overlapping coverage corresponding to the target base station according to at least one electrical signal difference.

[0141] The device for determining the overlapping coverage provided by the embodiments of the present application obtains at least one first service information of a target base station in a first time in the serving cell of the present service. The first service information corresponds one-to-one to the terminal devices located within the coverage range (the serving cell of the present service) of the target base station. Each piece of first service information corresponding to a terminal device includes the first electrical signal corresponding to the target base station in the serving cell of the present service and the second electrical signals respectively corresponding to the target neighboring base stations in N target neighboring cells, where N is an integer greater than or equal to 1. Then, calculate the electrical signal difference corresponding to each piece of first service information. Specifically, the N second electrical signals in the first service information can be respectively converted into corresponding actual received power values to obtain N actual received power values. Thus, the sum operation can be directly performed on all the actual received power values to obtain the total power value, which can reflect the strength of the interference from the target neighboring base stations in the operation result (the total power value), and can more accurately measure the influence of the level of the target neighboring cell on the interference of the present cell (the serving cell where the target base station is located). Next, convert the total power value into a total electrical signal to obtain the total electrical signal corresponding to the first service information, and then subtract the first electrical signal corresponding to the target base station from the total electrical signal, so as to obtain the electrical signal difference corresponding to the first service information. This electrical signal difference can accurately measure the severity of the overlapping coverage. After calculating the electrical signal difference corresponding to each piece of first service information, next, according to the electrical signal differences corresponding to each piece of first service information, accurately measure the overlapping coverage degree corresponding to the target base station, thereby providing a more scientific and accurate basis for network optimization, helping to improve network quality, reduce interference, and enhance the user experience.
