Description

Technical Field

[0001] The present application relates to the field of mobile communication technologies, and in particular to a method, apparatus, device, and medium for positioning an area without 5G signal coverage. Background Art

[0002] Due to the high frequency of 5G-NR networks, which suffer from disadvantages such as high path loss and poor wall penetration, they are inferior to 4G-LTE networks in both shallow and deep coverage. Consequently, a significant proportion of 5G terminals in existing networks use the 4G network for reverse traffic. To improve this situation, it is necessary to identify the specific locations where 5G terminals are back-trafficked to the 4G network due to areas without 5G signal coverage. This can be achieved by adding indoor antennas and directional antennas to specifically strengthen 5G signal coverage in areas with high 5G terminal back-traffic.

[0003] Currently, cells with high 5G backflow are typically identified based on the ratio of the average daily 4G traffic of 5G terminals at the cell level to the average daily total 4G traffic of the cell. However, this method only confirms that 5G users are backflowing to the 4G network within the cell's coverage area. It cannot pinpoint the specific location, such as a building or street, or determine the cause of the backflow to the 4G network. This results in inaccurate and imprecise determination of areas without 5G signal coverage. Summary of the Invention

[0004] The present application provides a method, apparatus, device and medium for locating areas without 5G signal coverage, which are used to solve the problem of inaccurate and inaccurate 5G signal coverage areas determined based on the ratio of the daily average 4G traffic of cell-level 5G terminals to the daily average 4G total traffic of the cell.

[0005] In a first aspect, the present application provides a method for positioning an area without 5G signal coverage, comprising:

[0006] Obtain cell traffic record CTR data; the CTR data includes measurement reports corresponding to multiple 4G services;

[0007] Determine based on CTR data at least one 5G terminal that has not scanned the redirection release frequency after the 4G service ends;

[0008] The target longitude and latitude information of each 5G terminal that has not scanned the redirection release frequency point is determined according to the CTR data, and the area without 5G signal coverage is determined according to the corresponding position of each target longitude and latitude information.

[0009] In a second aspect, the present application provides a positioning device for an area without 5G signal coverage, comprising:

[0010] An acquisition module is used to obtain cell traffic record CTR data; the CTR data includes measurement reports corresponding to multiple 4G services;

[0011] A terminal determination module is used to determine, based on the CTR data, at least one 5G terminal that has not scanned the redirection release frequency after the 4G service ends;

[0012] The area determination module is used to determine the target longitude and latitude information of each 5G terminal that has not scanned the redirection release frequency point based on the CTR data, and determine the area without 5G signal coverage based on the corresponding position of each target longitude and latitude information.

[0013] In a third aspect, the present application provides an electronic device, comprising: a processor, and a memory communicatively connected to the processor;

[0014] The memory stores computer-executable instructions

[0015] The processor executes the computer-executable instructions stored in the memory to implement the method for positioning an area without 5G signal coverage as described in any of the above aspects.

[0016] In a fourth aspect, the present application provides a computer-readable storage medium, which stores computer-executable instructions. When the computer-executable instructions are executed by a processor, they are used to implement the method for positioning an area without 5G signal coverage as described in any of the above aspects.

[0017] In a fifth aspect, the present application provides a computer program product, comprising computer execution instructions, which, when executed by a processor, implement the method for positioning an area without 5G signal coverage as described in any of the above aspects.

[0018] The present application provides a method, apparatus, device, and medium for locating an area without 5G signal coverage. The method, apparatus, and medium obtain cell traffic record CTR data, including measurement reports corresponding to multiple 4G services. The method determines, based on the CTR data, at least one 5G terminal that has not scanned a redirection-released frequency point after the 4G service ends. The method also determines, based on the CTR data, the target latitude and longitude information of each 5G terminal that has not scanned a redirection-released frequency point, and determines an area without 5G signal coverage based on the corresponding location of each target latitude and longitude information. Because the cell traffic record CTR data includes various measurement reports reported by terminals, 5G terminals that are performing 4G services and have not scanned a redirection-released frequency point can be determined based solely on the cell traffic record CTR data. By obtaining 5G-capable terminals using a 4G network and their locations, the area without 5G signal coverage can be more accurately located. Furthermore, the located location is the location of the 5G terminal that has not scanned a redirection-released frequency point, rather than a 5G terminal that has reversed 4G traffic due to other reasons. Therefore, the location can be determined to be without 5G signal, and the determined area without 5G signal coverage is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0026] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0027] The terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. In the description of the following embodiments, "plurality" means more than two, unless otherwise specifically defined.

[0028] First, the prior art involved in the present invention is described and analyzed in detail.

[0029] Currently, cells with high 5G backflow are typically identified based on the ratio of the average daily 4G traffic of 5G terminals at the cell level to the average daily total 4G traffic of the cell. However, this method can only confirm that 5G users are backflowing to the 4G network within the cell's coverage area, but cannot accurately determine the specific location of the backflow, such as buildings or streets, resulting in inaccurate determination of areas without 5G signal coverage. Furthermore, since the lack of 5G coverage is only one factor that triggers backflow to the 4G network, this method cannot determine the specific cause of the backflow to the 4G network, resulting in inaccurate determination of areas without 5G signal coverage.

[0030] The inventors discovered in their research that by determining the location of the terminal that generates 4G reverse flow, the precise location of the 4G reverse flow can be determined, thereby accurately locating the area without 5G signal coverage; and in the process of performing business, the terminal will report various measurement reports, from which the location of the terminal and information such as whether the terminal generates reverse flow and whether it is in the 5G signal coverage area can be determined. Therefore, the area without 5G signal coverage can be determined through the measurement report. Therefore, the present application provides a method for locating the area without 5G signal coverage, obtaining the CTR data of the cell traffic record; the CTR data includes measurement reports corresponding to multiple 4G services; determining at least one 5G terminal that has not scanned the redirection release frequency point after the 4G service ends based on the CTR data; determining the target latitude and longitude information of each 5G terminal that has not scanned the redirection release frequency point based on the CTR data, and determining the area without 5G signal coverage based on the corresponding position of each target latitude and longitude information.

[0031] Figure 1 The application scenario diagram provided in the embodiment of this application is as follows: Figure 1 As shown, it includes: terminal 1, base station 2, and electronic device 3; when terminal 1 performs business in the cell corresponding to base station 2, it will send a measurement report to base station 2; electronic device 3 can obtain CTR data including the measurement report from base station 2, and perform a positioning method for an area without 5G signal coverage based on the CTR data corresponding to at least one cell, thereby determining the position of a 5G terminal that only provides 4G services and has not scanned the redirection release frequency based on the CTR data, and determining an area without 5G signal coverage based on the above-mentioned 5G terminal position.

[0032] In the technical solution of this application, the collection, storage, use, processing, transmission, provision and disclosure of information such as financial data or user data involved comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0033] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] Example 1

[0035] Figure 2 This is a flowchart of a method for locating an area without 5G signal coverage provided in Example 1 of the present application. This embodiment of the present application addresses the problem of inaccurate and inaccurate determination of an area without 5G signal coverage based on the ratio of the daily average 4G traffic of a cell-level 5G terminal to the daily average 4G total traffic of the cell, and provides a method for locating an area without 5G signal coverage. The method in this embodiment is applied to a device for locating an area without 5G signal coverage, and the device for locating an area without 5G signal coverage can be located in an electronic device. The electronic device can be a digital computer in various forms, such as a laptop computer, a desktop computer, a workbench, a personal digital assistant, a server, a blade server, a mainframe computer, and other suitable computers.

[0036] like Figure 2 As shown, the specific steps of this method are as follows:

[0037] Step S101: Acquire cell traffic record CTR data.

[0038] The CTR data includes measurement reports corresponding to multiple 4G services.

[0039] In the embodiment of the present application, CTR data corresponding to a single cell can be obtained, or CTR data corresponding to multiple cells can be obtained, and this embodiment of the present application does not limit this. If CTR data corresponding to multiple cells is obtained, when executing the method for locating an area without 5G signal coverage, it is not necessary to process the CTR data by cell. The target longitude and latitude information in multiple cells can be determined, and the area without 5G signal coverage can be determined based on the corresponding position of each target longitude and latitude information.

[0040] Optionally, before obtaining the CTR data of the cell traffic record, the CTR data can be preliminarily screened based on the ratio of the daily average 4G traffic of the cell-level 5G terminal to the daily average 4G total traffic of the cell, and the CTR data corresponding to the cell with a higher ratio can be obtained, so that the amount of data can be reduced when executing subsequent steps.

[0041] It should be understood that the coverage-triggered NR session has been enabled in the embodiment of the present application.

[0042] Step S102: Determine, based on the CTR data, that at least one 5G terminal whose redirection release frequency point has not been scanned after the 4G service ends.

[0043] Among them, the redirection release frequency is an available NR frequency, which is used to redirect 5G terminals from 4G to 5G.

[0044] It should be understood that CTR data records the signaling and measurement reports of call service related behaviors, which can be used to analyze service call events in the cell. CTR data can specifically include signaling and corresponding measurement reports during call service establishment, switching operations and channel release.

[0045] In the embodiment of the present application, when performing 4G services, the 5G terminal can scan for redirection and release frequencies, and report the scan results to the base station through a measurement report. Since the determined terminal is a 5G terminal performing 4G services, it can be determined that the terminal has a backflow phenomenon.

[0046] Specifically, the 5G terminal performing 4G services can be determined based on the signaling or measurement report in the CTR data; based on the measurement report reported by the 5G terminal during the 4G service, it can be determined whether the 5G terminal has scanned the redirection release frequency, thereby determining at least one 5G terminal that has not scanned the redirection release frequency after the 4G service ends.

[0047] Step S103: Determine the target longitude and latitude information of each 5G terminal that has not scanned the redirection release frequency point based on the CTR data, and determine the area without 5G signal coverage based on the corresponding position of each target longitude and latitude information.

[0048] The target longitude and latitude information is the longitude and latitude information reported by the 5G terminal that has not scanned the redirection release frequency when performing 4G services.

[0049] In an embodiment of the present application, the measurement report in the CTR data may include the latitude and longitude information reported by the terminal. After determining that the 5G terminal has not scanned the redirection release frequency after the 4G service ends, the latitude and longitude information reported by the corresponding 5G terminal when the 4G service was performed can be determined from the CTR data, and the latitude and longitude information can be determined as the target longitude and longitude information, and the area without 5G signal coverage can be determined based on the corresponding position of each target longitude and longitude information.

[0050] The method for locating an area without 5G signal coverage provided in an embodiment of the present application obtains cell traffic record CTR data; the CTR data includes measurement reports corresponding to multiple 4G services; at least one 5G terminal that has not scanned the redirection release frequency after the 4G service ends is determined based on the CTR data; the target latitude and longitude information of each 5G terminal that has not scanned the redirection release frequency is determined based on the CTR data, and the area without 5G signal coverage is determined based on the corresponding position of each target latitude and longitude information. Because the cell traffic record CTR data includes various measurement reports reported by the terminal, 5G terminals that are performing 4G services and have not scanned the redirection release frequency can be determined based solely on the cell traffic record CTR data. The area without 5G signal coverage is determined by obtaining terminals that support 5G using the 4G network and the location of the terminals. This allows for more accurate positioning of the area without 5G signal coverage, and the positioned location is the location of the 5G terminal that has not scanned the redirection release frequency, rather than the 5G terminal that has reversed 4G due to other reasons. Therefore, it can be determined that there is no 5G signal at that location, and the determined area without 5G signal coverage is more accurate.

[0051] Example 2

[0052] Based on any of the above embodiments, this embodiment involves a refinement of an implementation method for determining, according to CTR data, at least one 5G terminal that has not scanned the redirection release frequency after the 4G service ends in step S102, and specifically includes the following steps:

[0053] Step S201: Determine a first service identifier corresponding to an inter-system handover event measurement report in CTR data.

[0054] Among them, the inter-system switching event measurement report is reported when the 5G terminal falls back from the 5G network to the 4G network to establish a 4G service.

[0055] It should be understood that if the terminal supports 5G, the base station will issue the corresponding measurement control when the terminal accesses the 4G network for 4G services, and the CTR data will be recorded in the INTERNAL_EVENT_MEAS_CONFIG_B1_NR inter-system handover event measurement report. The inter-system handover event measurement report is an event-triggered measurement report, and the corresponding measurement control is used to determine the triggering conditions for triggering the inter-system handover event measurement report.

[0056] Specifically, the terminal service identification field is included in the inter-system switching event measurement report, the field value of the terminal service identification field in the inter-system switching event measurement report in the CTR data is determined, and the field value of the terminal service identification field in the inter-system switching event measurement report is determined as the first service identifier. In this embodiment of the present application, the terminal service identification field in the CTR data measurement report can be: UE_REF.

[0057] Step S202: Determine, based on the first service identifier and the mobility assessment measurement report in the CTR data, whether a 5G terminal whose redirection release frequency point has not been scanned after the 4G service ends.

[0058] In the embodiments of the present application, the method for determining a 5G terminal that has not scanned the redirection release frequency after the 4G service ends is not limited. According to the mobility assessment measurement report, it can be determined that the 5G terminal that has not scanned the redirection release frequency is a 5G terminal at a location without a 5G signal. According to the first service identifier, the corresponding terminal is a 5G terminal performing a 4G service, that is, a 5G terminal with reverse flow. By combining the two, it can be determined that the 5G terminal that has not scanned the redirection release frequency after the 4G service ends can be determined, so that the area without 5G signal coverage can be determined by the location of the terminal.

[0059] The following describes the method for locating an area without 5G signal coverage provided by the above embodiment with reference to a specific example. Figure 5 A flowchart of a method for positioning an area without 5G signal coverage is provided in Example 4 of this application, such as Figure 5 As shown, the following steps are included:

[0060] Step S301: Acquire cell traffic record CTR data, and determine the first service identifier corresponding to the inter-system handover event measurement report in the CTR data.

[0061] Step S302: Determine a first terminal mobility assessment measurement report whose terminal service identifier is a first service identifier from the CTR data.

[0062] In the embodiment of the present application, the mobility assessment measurement report is a periodically triggered measurement report, and the mobility assessment measurement report includes a terminal service identification field; the terminal service identification field value can be determined from the CTR data to be a first terminal mobility assessment measurement report of the first service identification. The first terminal mobility assessment measurement report is a mobility assessment measurement report reported by a 5G terminal performing a 4G service.

[0063] Step S303: Determine from the first terminal mobility assessment measurement report a second terminal mobility assessment measurement report in which the redirection release frequency field value is unavailable.

[0064] In an embodiment of the present application, the mobility assessment measurement report also includes a redirection release frequency field; a second terminal mobility assessment measurement report can be determined from the first terminal mobility assessment measurement report to be unavailable, wherein the second terminal mobility assessment measurement report is a mobility assessment measurement report reported by a 5G terminal that has not scanned the redirection release frequency after the 4G service ends.

[0065] For example, the mobility assessment measurement report in the CTR data may be: INTERNAL_EVENT_UE_MOBILITY_EVAL, and the redirection release frequency field in the mobility assessment measurement report may be: EVENT_PARAM_REDIRECT_RELEASE_INFO.

[0066] Step S304: Determine the second service identifier corresponding to the mobility assessment measurement report of the second terminal.

[0067] Step S305: Determine the terminal corresponding to the second service identifier as a 5G terminal that has not scanned the redirection release frequency after the 4G service ends.

[0068] Specifically, the field value of the terminal service identifier field in the second terminal mobility assessment measurement report is obtained, and the obtained terminal service identifier is determined as the second service identifier; the terminal corresponding to the second service identifier is determined to be a 5G terminal that has not scanned the redirection release frequency after the 4G service ends. It can be determined that the location of the 5G terminal that has not scanned the redirection release frequency after the 4G service ends is in an area without 5G signal coverage.

[0069] Among them, the second service identifier is the identifier of the 4G service corresponding to the redirection release frequency point that the 5G terminal did not scan when performing the 4G service.

[0070] The embodiment of the present application provides a method for positioning an area without 5G signal coverage, which determines from CTR data a first terminal mobility assessment measurement report whose terminal service identifier is a first service identifier; the first terminal mobility assessment measurement report is a mobility assessment measurement report reported by a 5G terminal performing a 4G service; from the first terminal mobility assessment measurement report, it is determined that a second terminal mobility assessment measurement report has a redirection release frequency field value that is unavailable; the second terminal mobility assessment measurement report is a mobility assessment measurement report reported by a 5G terminal that has not scanned the redirection release frequency after the 4G service ends; the second service identifier corresponding to the second terminal mobility assessment measurement report is determined; and the terminal corresponding to the second service identifier is determined to be a 5G terminal that has not scanned the redirection release frequency after the 4G service ends. By filtering out the first terminal mobility assessment measurement report corresponding to the 5G terminal that generates backflow according to the first service identifier, and then filtering out at least one 5G terminal that has not scanned the redirection release frequency according to the first terminal mobility assessment measurement report, the amount of data when determining at least one 5G terminal that has not scanned the redirection release frequency after the 4G service ends can be reduced, the efficiency of determining at least one 5G terminal that has not scanned the redirection release frequency can be improved, and the efficiency of determining areas without 5G signal coverage can be further improved.

[0071] Step S306: Determine, from the CTR data, a target minimization of drive tests (MDT) measurement report in which the terminal service identifier is the second service identifier.

[0072] In this embodiment of the present application, the terminal corresponding to the second service identifier is a 5G terminal that has not scanned the redirection release frequency after the 4G service ends, and the terminal corresponding to the second service identifier is located in an area without 5G signal coverage. The target Minimization of Drive Test (MDT) measurement report is a Minimization of Drive Test (MDT) measurement report reported by a 5G terminal that has not scanned the redirection release frequency. The Minimization of Drive Test (MDT) measurement report includes a terminal service identifier field.

[0073] Specifically, a minimization of drive tests (MDT) measurement report may be acquired from the CTR data, and the minimization of drive tests (MDT) measurement report with the terminal service identifier being the second service identifier may be determined as the target minimization of drive tests (MDT) measurement report.

[0074] Step S307: Obtain target latitude and longitude information in the target minimization of drive tests (MDT) measurement report.

[0075] The minimization of drive tests (MDT) measurement report includes a latitude and longitude information field. After determining the target minimization of drive tests (MDT) measurement report, the target latitude and longitude information in the target minimization of drive tests (MDT) measurement report can be obtained.

[0076] For example, the minimization of drive tests (MDT) measurement report in the CTR data may be: INTERNAL_PER_UE_MDT_M1_REPORT, and the latitude and longitude information field of the minimization of drive tests (MDT) measurement report may be: EVENT_PARAM_MDT_M1_ELLIPSOID_POINT_WITH_ALT.

[0077] In the embodiment of the present application, the target longitude and latitude information in the target minimization of drive test (MDT) measurement report is the location information reported by the terminal in the area without 5G signal coverage. The area without 5G signal coverage can be determined based on the target longitude and latitude information.

[0078] The method for locating an area without 5G signal coverage provided in an embodiment of the present application determines from CTR data a target minimization drive test MDT measurement report whose terminal service identifier is a second service identifier; the target minimization drive test MDT measurement report is a minimization drive test MDT measurement report reported by a 5G terminal that has not scanned the redirection release frequency point; and the target longitude and latitude information in the target minimization drive test MDT measurement report is obtained. The location of the terminal corresponding to the second service identifier is in an area without 5G signal coverage, so the target longitude and latitude information determined according to the second service identifier is the location information reported by the terminal in the area without 5G signal coverage. Determining an area without 5G signal coverage based on the target longitude and latitude information can improve the accuracy of determining an area without 5G signal coverage.

[0079] Step S308: Calculate the target longitude and latitude information according to a preset longitude and latitude calculation strategy, and determine the calculation result as the longitude and latitude corresponding to the target longitude and latitude information.

[0080] In the embodiment of the present application, the target longitude and latitude information may be expressed in latitude and longitude according to the 3GPP positioning protocol, and the target longitude and latitude information needs to be calculated according to a preset longitude and latitude calculation strategy to obtain the corresponding longitude and latitude.

[0081] Exemplarily, the target longitude and latitude information is 38B51FD2D379. Specifically, the preset longitude and latitude calculation strategy can be: take the first six characters 38B51F in the target longitude and latitude information, and convert 38B51F from hexadecimal to decimal to obtain 3716383; determine 3716383 as X and substitute it into the formula (X+0.5)*90 / 2^23 to obtain 39.8724693, and the calculation result is the latitude corresponding to the target longitude and latitude information; take the last six characters D2D379 in the target longitude and latitude information, and convert D2D379 from hexadecimal to decimal to obtain 13816697; determine 13816697 as Y and substitute it into the formula (Y+0.5)*360 / 2^24-180 to obtain 116.474164, and the calculation result is the longitude corresponding to the target longitude and latitude information.

[0082] Step S309: Determine the corresponding longitude and latitude location set whose spacing is less than a preset threshold as an area without 5G signal coverage.

[0083] In an embodiment of the present application, the spacing of the corresponding longitude and latitude positions can be calculated based on the longitude and latitude corresponding to each target longitude and latitude information, and it can be determined that the corresponding longitude and latitude positions with a spacing less than a preset threshold are in the same area without 5G signal coverage, and the set of corresponding longitude and latitude positions with a spacing less than the preset threshold can be determined as an area without 5G signal coverage.

[0084] The method for locating an area without 5G signal coverage provided in an embodiment of the present application calculates the target longitude and latitude information according to a preset longitude and latitude calculation strategy, and determines the calculation result as the longitude and latitude corresponding to the target longitude and latitude information; and determines the set of corresponding longitude and latitude locations with a spacing less than a preset threshold as an area without 5G signal coverage. Determining the set of longitude and latitude locations as an area without 5G signal coverage eliminates the need to check for areas without 5G signal coverage according to each corresponding longitude and latitude, thereby reducing the number of areas determined without 5G signal coverage and improving the efficiency of checking and optimizing areas without 5G signal coverage.

[0085] Figure 3 The terminal and signal coverage area diagram provided for this application is as follows: Figure 3As shown, the location of terminal 1 has both 5G and 4G signals, and the CTR data contains a measurement report of an inter-system switching event corresponding to terminal 1. This indicates that terminal 1 supports the 5G function and has fallen back to the 4G network to establish a 4G service. Based on the CTR data, it is determined that terminal 1 has scanned the redirection release frequency, which indicates that a 5G signal exists at the location of terminal 1 and has triggered the quick return function, allowing the terminal to quickly return to the 5G network after ending the 4G service. The location of terminal 2 has both 5G and 4G signals. If the CTR data does not contain a measurement report of an inter-system switching event corresponding to terminal 2, it indicates that terminal 2 does not support the 5G function or supports the 5G function but does not use the 4G network. Terminal 2 has not generated backflow, and it is impossible to determine whether terminal 2 has a 5G signal. There is a 4G signal at the location of terminal 3, but no 5G signal coverage; there is a different system switching event measurement report corresponding to terminal 3 in the CTR data, which determines that terminal 3 supports 5G function and falls back to the 4G network to establish 4G service; according to the CTR data, it is determined that terminal 3 did not scan the redirection release frequency point, so it can be determined that there is no 5G signal at the location of terminal 3 and it is located in an area without 5G signal coverage. The latitude and longitude of the location of terminal 3 can be determined according to the minimized drive test (MDT) measurement report corresponding to terminal 3, thereby determining the area without 5G signal coverage; and according to the minimized drive test (MDT) measurement report corresponding to terminal 3, the 4G traffic generated by terminal 3 in the area without 5G signal coverage can be determined.

[0086] Example 3

[0087] On the basis of any of the above embodiments, after determining the area without 5G signal coverage, the priority to be optimized of each area without 5G signal coverage may be determined, so as to optimize the 5G signal for each area without 5G signal coverage according to the priority to be optimized. Specifically, the following steps may be included:

[0088] Step S401: Determine the total amount of 4G traffic generated by 4G services performed by 5G terminals corresponding to each area without 5G signal coverage based on CTR data.

[0089] In the embodiment of the present application, the CTR data may include the total amount of traffic generated by each service. After determining the 5G terminals corresponding to the areas without 5G signal coverage, the total amount of 4G traffic generated by the terminals when performing 4G services can be determined based on the CTR data.

[0090] Optionally, a method for determining the total amount of 4G traffic generated by 5G terminals corresponding to each area without 5G signal coverage performing 4G services based on CTR data includes the following steps:

[0091] Step S4011: Determine the third service identifier corresponding to each area without 5G signal coverage according to the target minimization of drive tests (MDT) measurement report.

[0092] Among them, the third service identifier is the service identifier of the 5G terminal performing 4G service in the area without 5G signal coverage.

[0093] Specifically, the target minimization of drive test (MDT) measurement report corresponding to each area without 5G signal coverage is determined, and the service identifier in the corresponding target minimization of drive test (MDT) measurement report is determined as the third service identifier corresponding to the area without 5G signal coverage.

[0094] Step S4012: Determine from the CTR data the target terminal traffic measurement report whose terminal service identifier field value is the third service identifier.

[0095] The target terminal traffic measurement report is a terminal traffic measurement report reported by a 5G terminal in the area without 5G signal coverage. The terminal traffic measurement report includes a terminal service identification field and the traffic value corresponding to the service.

[0096] Specifically, the target terminal traffic measurement report can be obtained from the CTR data, and the target terminal traffic measurement report with the terminal service identifier as the third service identifier is determined as the target terminal traffic measurement report corresponding to the area without 5G signal coverage.

[0097] Step S4013: Obtain the traffic value in the target terminal traffic measurement report, and determine the sum of the traffic values ​​in the traffic measurement reports of each target terminal as the total 4G traffic generated by the 5G terminal corresponding to the area without 5G signal coverage for 4G services.

[0098] Specifically, the traffic values ​​in the traffic measurement reports of the target terminals corresponding to the same area without 5G signal coverage are added, and the calculation result is determined as the total 4G traffic generated by the 5G terminals corresponding to the area without 5G signal coverage performing 4G services.

[0099] The method for locating an area without 5G signal coverage provided in an embodiment of the present application determines the third service identifier corresponding to each area without 5G signal coverage based on a target minimized drive test (MDT) measurement report; the third service identifier is a service identifier for a 5G terminal performing 4G services in the area without 5G signal coverage; a target terminal traffic measurement report whose terminal service identifier field value is the third service identifier is determined from CTR data; the traffic value in the target terminal traffic measurement report is obtained, and the sum of the traffic values ​​in each target terminal traffic measurement report is determined as the total 4G traffic generated by the 5G terminal corresponding to the area without 5G signal coverage performing 4G services. Determining the third service identifier based on the target minimized drive test (MDT) measurement report, rather than based on all minimized drive test (MDT) measurement reports, can reduce the amount of data, improve the efficiency of determining the third service identifier, and thus improve the efficiency of determining the total 4G traffic.

[0100] Step S402: Sort the areas without 5G signal coverage in descending order of the total amount of 4G traffic, and determine the priority of the areas without 5G signal coverage to be optimized based on the sorting results of the areas without 5G signal coverage.

[0101] Step S403: Send the priority of each area without 5G signal coverage to be optimized to the maintenance terminal, so as to optimize each area without 5G signal coverage based on the priority to be optimized.

[0102] In an embodiment of the present application, after determining the total amount of 4G traffic generated by the 5G terminals corresponding to each area without 5G signal coverage performing 4G services, the areas without 5G signal coverage can be sorted according to the size of the determined total amount of 4G traffic and the priority to be optimized can be determined, so as to give priority to optimizing the 5G signals in the areas without 5G signal coverage with higher optimization priority.

[0103] The embodiment of the present application provides a method for locating areas without 5G signal coverage. The method determines the total amount of 4G traffic generated by 5G terminals performing 4G services corresponding to each area without 5G signal coverage based on CTR data; sorts each area without 5G signal coverage in order of the total amount of 4G traffic from high to low, and determines the priority of each area without 5G signal coverage to be optimized based on the sorting results of each area without 5G signal coverage; and sends the priority of each area without 5G signal coverage to a maintenance terminal to optimize each area without 5G signal coverage based on the priority to be optimized. The priority to be optimized of each area without 5G signal coverage is determined based on the total amount of 4G traffic generated by 5G terminals performing 4G services. It can be determined that the total amount of 4G traffic is all caused by the backflow of the 5G signal to the 4G. Compared with the total amount of 4G traffic generated by any terminal performing 4G services, the priority to be optimized of each area without 5G signal coverage can be determined more accurately. The area with more traffic backflowing to the 4G network can be targeted according to the priority to be optimized. Accurate optimization targets can be provided, which helps save optimization costs and can accurately improve and solve the needs of 5G users for using the 5G network.
