Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular to a method and device for verifying the user rate difference problem of multiple operators sharing a network. Background Art

[0002] Due to the settings of frequencies and handover strategies of different operators in multiple operators sharing a network, it will cause multiple operators sharing the network to use cells with different bandwidths, resulting in differences in 4G / 5G network rates of different operators under the same shared network in the evaluation results of network quality evaluation. In areas with comparable coverage, the differences are significant in some regions. Moreover, the inconsistent experiences of users of different operators on the shared network are difficult to discover through traditional KPI indicator verification, and it is difficult to locate the areas with rate differences in the network quality test of multiple operators.

The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0069] Before elaborating on the embodiments of the present invention in detail, some nouns and terms involved in the embodiments of the present invention are first explained, and the nouns and terms involved in the embodiments of the present invention are applicable to the following explanations.

[0070] The primary cell refers to the cell to which a mobile terminal (such as a mobile phone) is currently connected and mainly relies on for communication. A cell is an area covered by a base station in a mobile communication network, and the base station provides communication services for terminal devices within this area through wireless signals.

[0071] The in-network cell is the cell that is currently actually operating in the network and is the basis for network planning and optimization. The primary cell is one of the in-network cells.

[0072] The primary serving cell is the cell to which a user equipment (UE) is currently connected and from which it receives services. It is the cell that the user equipment actually accesses and communicates in the mobile communication network.

[0073] OTT-MR data is the relevant sampling point data obtained by these applications and services through the measurement information and longitude and latitude information of the mobile phone, including the operator used by the mobile phone user, network type, longitude and latitude, frequency point, network mode, cell ID, RSRP, WIFI information used by the user, etc. These information do not include sensitive information such as user numbers and user identities. OTT data is the data collected by applications and services that provide various services and content through the operator's network.

[0074] The network type indicates whether the sampling point is a 4G signal or a 5G signal, and there is currently no 2G / 3G signal.

[0075] The frequency point refers to a specific frequency or frequency range used in wireless communication for transmitting information between a mobile device (such as a mobile phone) and a base station.

[0076] Cell ID, also known as cellular ID in mobile communication networks, is an identifier used to uniquely identify a base station coverage area (i.e., cell). Each base station can serve one or more cells, and each cell has its own Cell ID, which helps the network identify the specific location where user equipment (such as mobile phones) is connected and manage wireless resources.

[0077] RSRP (Reference Signal Receiving Power) is a key parameter that can represent the strength of wireless signals in LTE networks and one of the physical layer measurement requirements. It is the average value of the signal power received on all REs (resource elements) that carry reference signals in a symbol. LTE (Long-Term Evolution) is a mobile communication standard.

[0078] A multi-operator shared network refers to a communication network built and shared by multiple operators in cooperation. This cooperation mainly occurs at the wireless access network level, that is, the construction and use of equipment such as base stations and antennas, while the core network is operated independently. That is, users of different operators can use the networks of other operators among the multiple operators.

[0079] After multiple operators share 4G / 5G networks, whether users of different operators have the same experience on the shared network is a question that multiple operators are concerned about. Due to the settings of different frequencies and switching strategies of multiple operators in the shared network, users of multiple operators in the shared network will use cells with different bandwidths, resulting in the evaluation results of network quality evaluation showing that different operators have different 4G / 5G network speeds on the same shared network. In the case of comparable coverage, some areas have significant differences.

[0080] Moreover, after multiple operators share 4G / 5G networks, it is difficult to verify whether the experience of users of different operators on the shared network is consistent through traditional KPI indicators, and it is difficult to locate the area of ​​rate differences in multiple operators' tests. This is because when users of different operators are in the same cell, their resource priorities are the same, and there is no difference in rate. However, it is a consensus shared by multiple parties to use the same switching and resident strategies for users of multiple operators in the shared network, such as giving priority to local users to stay on their own network, or using A3 switching for both parties, and using the one with the stronger signal. However, in one area, the frequency configurations and bandwidths of multiple operators sharing the network vary greatly, and need to be personalized according to different scenarios, loads, and coverage conditions. However, manually identifying problem areas and carrying out personalized settings is a huge workload, so the operation and maintenance personnel of multiple operators usually choose a unified strategy for the entire network. If they receive user complaints, they will initiate personalized optimization. If the speed is within an acceptable range, for example, in the same area, the user speed of one operator is 10Mbps and the user speed of the other operator is 50Mbps, since both speeds can meet the needs of users for daily use of application software, there is almost no difference in perception between users on both sides. Therefore, such problems are difficult to discover through user complaints, resulting in the problem of multi-operator speed differences during the network quality testing process.

[0081] In view of this, if Figure 1 As shown, the embodiment of the present invention provides a method for checking user rate difference problems of multiple operators in a shared network. The method may include but is not limited to step S100 to step S500:

[0082] Step S100, obtaining bandwidth data of a target sampling point, performing a rasterization operation on the bandwidth data, and obtaining a first bandwidth raster map;

[0083] Step S200, aligning the first bandwidth grid graphs with the same network type and different operators to obtain a second bandwidth grid graph;

[0084] Step S300, obtaining a bandwidth difference of the second bandwidth grid map, and obtaining a difference grid map according to the second bandwidth grid map and the bandwidth difference;

[0085] Step S400, obtaining an abnormal grid threshold according to the bandwidth difference;

[0086] Step S500: performing grid extraction and aggregation operations on the difference grid image according to the abnormal grid threshold to obtain the problem area.

[0087] In steps S100 to S500 of some embodiments, after obtaining the bandwidth data of the target sampling points, by rasterizing the bandwidth data, combining the alignment of the bandwidth raster map, the calculation of the raster bandwidth difference, and the determination of the abnormal raster threshold, the contiguous problem area is located, providing a direction for verifying the user rate difference problem of multiple operators in the shared network, guiding the implementation of personalized optimization settings, and improving the accuracy of verifying the test rate difference problem and locating the problem area in the multiple-operator shared network.

[0088] In some embodiments, as Figure 2 shown, by analyzing the OTT-MR data, the bandwidth data is rasterized to locate contiguous areas with excessive differences in the wireless bandwidth used by multiple operators in the shared network. This method is based on the purchased OTT-MR data or on the premise that the AGPS-MR data of each party among multiple operators has been obtained, and has the following step process:

[0089] Step 1: Rasterize the OTT-MR sampling point data

[0090] Determine a common reference point. Based on the selected reference point, establish four different types of bandwidth raster maps, including the 4G bandwidth raster of the first operator's users, the 4G bandwidth raster of the second operator's users, the 5G bandwidth raster of the first operator's users, and the 5G bandwidth raster of the first operator's users.

[0091] Step 2: Align the rasters and fill in the paired null-value rasters

[0092] Filter the single-party null-value rasters, take the average bandwidth value of the same operator in the surrounding N rasters as the filling of the null-value raster, and select the primary cell with the highest frequency in the surrounding N rasters as the primary cell of the filled raster; if there is no bandwidth value of the same operator in the surrounding N rasters, the null-value raster is not processed.

[0093] Step 3: Calculate the raster bandwidth difference of the same radio access technology (same network type)

[0094] Calculate the difference in bandwidth values for the paired rasters of different operators with the same network type, and there are bandwidth values of their respective operators for both paired rasters. If there is no corresponding bandwidth value for one or both rasters, then eliminate that raster and output the difference raster map.

[0095] Step 4: Determine the abnormal raster threshold

[0096] Sort the bandwidth differences in descending order, and use the threshold values of the top N% as the first threshold; the threshold values of the bottom N% as the second threshold.

[0097] Step 5: Locate the contiguous problem area

[0098] Extract the grids in the difference raster map that are greater than the first threshold, and aggregate them using the DBSCAN technique. If the number of aggregated grids is greater than or equal to 10, include them in the first contiguous area set. Extract the grids in the difference raster map that are less than the second threshold, and aggregate them using the DBSCAN technique. If the number of aggregated grids is greater than or equal to 10, include them in the second contiguous area set. Both sets are contiguous problem sets.

[0099] Step 6: Output the verification direction

[0100] For the contiguous problem sets generated in step 5, respectively output the list of primary cells of the grids in the set, divided into the primary cell set of the first operator and the primary cell set of the second operator, and sort and output according to the number of occurrences in the grids, so as to provide the front-line optimization personnel with the configuration strategy problems such as frequency and neighboring cells between multi-operator cells of the shared network for targeted verification, and carry out targeted optimization, etc.

[0101] In step S100 of some embodiments, as Figure 3 shown, four preset bandwidth raster maps of 20 meters × 20 meters are created using the same reference points. By assigning a wireless bandwidth value to each target sampling point, extracting the sampling points of the same network type, recording the operator to which the sampling point belongs, and attributing the sampling points to the corresponding 20-meter × 20-meter bandwidth raster map according to the longitude and latitude positions, a first bandwidth raster map can be obtained, including the 4G bandwidth raster of the first operator's users, the 4G bandwidth raster of the second operator's users, the 5G bandwidth raster of the first operator's users, and the 5G bandwidth raster of the first operator's users. After obtaining the first bandwidth raster map, the primary cells of the grids in the first bandwidth raster map are also calculated, which can be used to prompt the cells that need to be verified later.

[0102] In some embodiments, step S100 may include but is not limited to steps S110 to S160:

[0103] Step S110, preset several preset raster maps according to the network type and the operator to which it belongs;

[0104] Step S120, obtain the target sampling points of the OTT-MR data, extract the primary cells of the target sampling points, and assign a first wireless bandwidth value to the target sampling points according to the bandwidth data of the primary cells;

[0105] Step S130, extract the target sampling points according to the network type and the operator to which it belongs to obtain the first sampling points;

[0106] Step S140, obtain the longitude and latitude information of the first sampling points, and assign the first sampling points to the preset raster maps according to the longitude and latitude information;

[0107] Step S150: Obtain the first average bandwidth value of all the first sampling points in the preset grid map according to the first wireless bandwidth value;

[0108] Step S160: Obtain a plurality of first bandwidth grid maps according to the preset grid map and the first average bandwidth value.

[0109] In step S110 of some embodiments, multiple preset grid maps can be set according to the network type and the affiliated operator. Optionally, the network type includes 4G network and 5G network, and the affiliated operator includes the first operator and the second operator. Then, according to the network type and the affiliated operator, four types of 20 m × 20 m preset grid maps can be pre-created.

[0110] In step S120 of some embodiments, based on the target sampling points of OTT-MR data, extract the serving cell of the target sampling points, and assign a wireless bandwidth value to the sampling points according to the bandwidth information configured by the in-network cells, that is, the wireless bandwidth of the target sampling points is the wireless bandwidth value of the serving cell.

[0111] In steps S130 to S160 of some embodiments, according to the selected network type and the affiliated operator, extract the target sampling points, and classify the extracted first sampling points into the 20 m × 20 m preset grid maps corresponding to both the network type and the affiliated operator according to their longitude and latitude information. Then, for each preset grid map assigned with first sampling points, record the bandwidth values of all the first sampling points and calculate the bandwidth average value, and thus the first average bandwidth value of this preset grid map can be obtained, forming a first bandwidth grid map.

[0112] In some embodiments, the serving cell of the grid in the formed first bandwidth grid map is also calculated. Optionally, within each grid, count all the sampling points belonging to the same serving cell, mark the serving cell with the most sampling points as the serving cell of this first bandwidth grid map, and record the serving cell of this first bandwidth grid map, which can be used to prompt the cell that needs to be verified later.

[0113] In some embodiments, as Figure 4 shown, taking the 4G bandwidth grid of the first operator as an example, the generation steps of the first bandwidth grid map are as follows:

[0114] Step 1: Extract sampling points from the OTT-MR data, extract the serving cell of each sampling point, and assign a wireless bandwidth value to the sampling points according to the bandwidth information configured by the serving cell in the in-network.

[0115] Step 2: Select the sampling points whose affiliated operator is the first operator, and classify these sampling points into the corresponding 20-meter * 20-meter grid map according to their longitude and latitude information. For each grid containing sampling points, record the bandwidth values of all sampling points to obtain the average bandwidth value of the grid, thereby forming the 4G bandwidth grid of the first operator.

[0116] Step 3: In each grid, count all the sampling points belonging to the same primary cell. The primary cell with the most sampling points (i.e., the primary cell with the highest frequency) is used as the primary cell of the 4G bandwidth grid of the first operator.

[0117] In some embodiments, due to the differences in the sampling amounts and sampling users among different operators in the shared network, there will be cases where some grids have values for only one operator. Therefore, the embodiments of the present invention also compare the grids. Optionally, in the shared network with multiple operators including the first operator and the second operator, due to the differences in the sampling amounts (i.e., sampling users) between the first operator and the second operator, there will be cases where some grids have values for one party while having no values for the other party. By aligning the grids of both parties, it is convenient to compare the grids of both parties.

[0118] In some embodiments, step S200 may include but is not limited to steps S210 to S250:

[0119] Step S210: Take the first bandwidth grid map belonging to the first operator as the first intermediate grid map, and take the first bandwidth grid map belonging to the second operator as the second intermediate grid map; the affiliated operators include the first operator and the second operator;

[0120] Step S220: Based on the same network type, compare the first grid in the first intermediate grid map with the second grid in the second intermediate grid map; the first position coordinate of the first grid in the first intermediate grid map corresponds to the second position coordinate of the second grid in the second intermediate grid map;

[0121] Step S230: If the first grid lacks the second wireless bandwidth value and the second grid has the third wireless bandwidth value, then identify the first grid as an empty value grid; if the second grid lacks the third wireless bandwidth value and the first grid has the second wireless bandwidth value, then identify the second grid as an empty value grid;

[0122] Step S240: Taking the empty value grid as the center, obtain the second average bandwidth values of several surrounding grids; the affiliated operator of the surrounding grids is the same as that of the empty value grid;

[0123] Step S250: Fill the second average bandwidth values of the surrounding grids into the empty value grid.

[0124] In steps S210 to S230 of some embodiments, for two grids of the same network type (i.e., both 4G or 5G networks) but different affiliated operators, grids where only one operator has a value and the other operator's value is empty are screened out, and the grid with an empty value is used as the empty-value grid. Among them, the position coordinates of the two grids being compared in their respective bandwidth grid maps correspond to each other.

[0125] In steps S240 to S250 of some embodiments, with the empty-value grid as the center, several surrounding grids are traversed. If there are bandwidth values belonging to the same operator as the grid with a missing value, the average of these bandwidth values is used to fill the empty-value grid. If there are no bandwidth values belonging to the same operator among the several surrounding grids, the empty-value grid is not filled. By analogy, all grids with only one value are traversed, the missing values are filled, and the two grids are aligned.

[0126] In some embodiments, as Figure 5 shown, taking the first operator and the second operator as examples, the steps for multi-operator grid alignment are as follows:

[0127] Step 1, comparison of grids of the same standard: For the grids of the first operator and the second operator of the same network type, identify the empty-value grids where only one operator has a value and the other operator's value is empty.

[0128] Step 2, filling of adjacent grids: For these empty-value grids, check M surrounding grids with the empty-value grid as the center. If there are bandwidth values of the same operator, the average of these bandwidth values is filled into the corresponding empty-value grid. And the primary cell of the filled grid selects the primary cell that appears the most times among the M surrounding grids with values. If there are no available bandwidth values of the same operator among the M surrounding grids, the empty-value grid is not filled.

[0129] Exemplarily, if grid A only has the bandwidth value of the first operator and no bandwidth value of the second operator, then the average of all the bandwidth values of the second operator among the surrounding 8 grids is calculated to fill the bandwidth value of the second operator in grid A. The primary cell of the filled grid selects the primary cell that appears the most times among the 8 surrounding grids with values. If there are no available Unicom values among the 8 surrounding grids, the empty-value grid is not filled.

[0130] All grids with only one value are traversed in sequence, and the missing values are filled according to the above method, thereby achieving the alignment of the two-grid data. The multi-operator grid alignment effectively utilizes the data in the adjacent area to make up for the problem of insufficient sampling, improving the data integrity and the accuracy of subsequent data comparison and analysis.

[0131] In some embodiments, step S300 may include, but is not limited to, steps S310 to S330:

[0132] Step S310, taking the second bandwidth raster map belonging to the first operator as the third intermediate raster map, and taking the second bandwidth raster map belonging to the second operator as the fourth intermediate raster map;

[0133] Step S320, when there is a fourth radio bandwidth value in the third raster of the third intermediate raster map and there is a fifth radio bandwidth value in the fourth raster of the fourth intermediate raster map, obtaining the bandwidth difference between the fifth radio bandwidth value and the fourth radio bandwidth value; the third position coordinate of the third raster in the third intermediate raster map corresponds to the fourth position coordinate of the fourth raster in the fourth intermediate raster map;

[0134] Step S330, generating the difference raster map according to the fourth radio bandwidth value, the fifth radio bandwidth value, the bandwidth difference, the third position coordinate, and the fourth position coordinate.

[0135] In steps S310 to S330 of some embodiments, the bandwidth value difference calculation is performed on the grids of both parties of different operators with the same network type, and there are bandwidth values of their respective operators for both parties of the grids. If there is a bandwidth value for one party of the grids or there is no corresponding bandwidth value for both parties of the grids, then this grid is excluded, and the difference raster map is output. Exemplarily, as Figure 6 shown, only when there are respectively a bandwidth value of the first operator and a bandwidth value of the second operator of the same network type (such as 4G / 5G) in the grids at the same position coordinates of both parties, the difference calculation is performed. Optionally, the bandwidth difference = the bandwidth value of the second operator - the bandwidth value of the first operator. Keep this bandwidth difference and associate it with the position coordinates of the corresponding grid in the raster map. At the same time, a new raster layer is generated, and the difference raster map can be obtained. This difference raster map only contains the grid cells with dual-operator data and the bandwidth difference. The attribute fields of each valid grid cell in the difference raster map record the original bandwidth value of the first operator, the bandwidth value of the second operator, and the bandwidth difference. If there is only a bandwidth value for one party of the grids and no bandwidth value for the other party of the grids, or there is no bandwidth value for both parties of the grids, then this grid is directly excluded.

[0136] In some embodiments, step S400 may include, but is not limited to, steps S410 to S430:

[0137] Step S410, sorting the bandwidth differences in descending order to obtain an ordered sequence;

[0138] Step S420, selecting the minimum value of the first several bandwidth differences sorted in the front in the ordered sequence as the first threshold;

[0139] Step S430: Select the maximum value among several subsequent bandwidth differences in the ordered sequence as the second threshold.

[0140] In steps S410 to S430 of some embodiments, the bandwidth differences are sorted in descending order to obtain an ordered sequence. The minimum value among the top N% (N is a variable value, usually taken as 10) in the ordered sequence is used as the first threshold, and the maximum value among the last N% (e.g., 10%) in the ordered sequence is used as the second threshold.

[0141] In some embodiments, as Figure 7 shown, taking the first operator and the second operator as examples, the steps to determine the anomaly threshold are as follows:

[0142] Step 1: Sort the generated bandwidth differences (second operator bandwidth value - first operator bandwidth value) in descending order of numerical value to generate an ordered sequence.

[0143] Step 2: Define dynamic thresholds:

[0144] Second operator advantage anomaly threshold (Threshold_1): Take the minimum value among the top N% (e.g., 10%) in the ordered sequence as the first threshold. Then, the grids that satisfy the bandwidth difference being greater than or equal to the first threshold are regarded as the anomaly areas where the second operator is significantly better than the first operator.

[0145] First operator advantage anomaly threshold (Threshold_2): Take the maximum value among the last N% (e.g., 10%) in the ordered sequence as the second threshold. Then, the grids that satisfy the bandwidth difference being less than or equal to the second threshold are regarded as the anomaly areas where the first operator is significantly better than the second operator.

[0146] By covering the two extreme cases of the bandwidth difference distribution through the dual - threshold logic, one - sided deviation omission can be effectively avoided. Optionally, the parameter N is an adjustable proportional value (default 10%), and the user can dynamically adjust it according to business requirements.

[0147] In some embodiments, step S500 may include but is not limited to steps S510 to S570:

[0148] Step S510: Extract the fifth grids in the difference grid map that are greater than the first threshold.

[0149] Step S520: Aggregate the fifth grids through the DBSCAN aggregation algorithm to obtain the first grid quantity.

[0150] Step S530: When the first grid quantity is greater than or equal to the first preset value, include the fifth grids in the first contiguous area set.

[0151] Step S540: Extract the sixth grid cells in the difference grid map that are less than the second threshold;

[0152] Step S550: Aggregate the sixth grid cells through the DBSCAN clustering algorithm to obtain the number of the second grid cells;

[0153] Step S560: When the number of the second grid cells is greater than or equal to the second preset value, include the sixth grid cells in the second contiguous area set;

[0154] Step S570: Obtain the problem area according to the first contiguous area set and the second contiguous area set.

[0155] In steps S510 to S530 of some embodiments, as Figure 8 shown, extract the grid cells in the difference grid map that are greater than the first threshold, aggregate them using the DBSCAN technology, and if the number of aggregated grid cells is greater than or equal to 10, include them in the first contiguous area set.

[0156] In steps S540 to S560 of some embodiments, as Figure 8 shown, extract the grid cells in the difference grid map that are less than the second threshold, aggregate them using the DBSCAN technology, and if the number of aggregated grid cells is greater than or equal to 10, include them in the second contiguous area set.

[0157] In step S560 of some embodiments, the contiguous problem area can be obtained according to the first contiguous area set and the second contiguous area set.

[0158] After step S500 of some embodiments, it may further include obtaining the first primary cell list of the first contiguous area set; dividing the first primary cell list according to the affiliated operator to obtain several first primary cell subsets; obtaining the second primary cell list of the second contiguous area set; dividing the second primary cell list according to the affiliated operator to obtain several second primary cell subsets. Exemplarily, for the two types of contiguous area sets, namely the generated first contiguous area set and the second contiguous area set, the primary cell list of the grid cells within the set is output respectively, divided into the first operator primary cell set and the second operator primary cell set, and sorted and output according to the number of occurrences in the grid cells. Provide it to the on-site optimization personnel to specifically check the configuration strategy issues such as frequency and neighboring cells between multi-operator cells in the shared network, and carry out targeted optimization, etc.

[0159] In practical applications, the method of the present invention analyzes 20 billion OTT-MR data of a certain area, and finds 11,032 4G difference areas, and the bandwidth difference values all exceed 7.5 MHz. The weak area list is issued for verifying difference problems, and the primary cells of the first operator and the second operator's grids are given. Optimization can be performed through the area number. The corresponding problem area can be queried on the system, and the frequency and neighboring cell relationship between the primary cells of multiple operators sharing the network can be verified according to the list prompt, quickly locating and solving the problem of large bandwidth differences for users of multiple operators sharing the network.

[0164] The fourth module 604 is used to obtain the abnormal raster threshold according to the bandwidth difference value;
