Description

Technical Field

[0001] This invention relates to a mobile network signal quality improvement technology, and more particularly to a signal quality improvement system, method, and computer-readable medium used in mobile network customer complaint hotspots. Prior Technology

[0002] With the rapid development of mobile networks, from the second generation (2G) to the fifth generation (5G), and even the future sixth generation (6G) or more advanced mobile networks, mobile networks have become an indispensable part of modern society. At the same time, with the increasing demand for high-quality voice calls, mobile internet access, and value-added applications, mobile network users have higher requirements for mobile network quality. Therefore, improving mobile network service quality, quickly locating areas with poor mobile network signal coverage, and / or evaluating the effectiveness of mobile network signal improvement have become crucial aspects of providing high-quality mobile network services.

[0003] Existing technology proposes a method for automatically optimizing mobile network cell coverage by considering field testing and customer complaint information. However, this existing technology cannot classify multiple customer complaint hotspots into high-complaint hotspots and low-complaint hotspots based on the number of customer complaints, nor can it identify areas with poor mobile network signal coverage (such as high-complaint hotspots), and it is not easy to improve the service quality of mobile networks.

[0004] Furthermore, this existing technology cannot utilize the average percentage of grid areas with signal strength below the signal strength threshold in high-complaint hotspots at different time points (such as the baseline period and the comparison period), nor can it utilize the improvement threshold for high-complaint hotspots. As a result, it is impossible to assess the effectiveness of improving the signal strength of high-complaint hotspots, nor can it improve the signal quality of high-complaint hotspots that have not reached the improvement threshold. Consequently, it is difficult to maintain or improve the good experience for mobile network users.

[0005] Therefore, how to provide an innovative mobile network signal quality improvement technology to solve any of the above problems, or to provide related systems and methods, has become a major research topic for those skilled in the art. Summary of the Invention

[0006] The signal quality improvement system for mobile network customer complaint hotspots described in this invention includes: a customer complaint hotspot data generation module, which divides the service area of ​​the mobile network into multiple grid areas or multiple customer complaint hotspots; a customer complaint data processing module, which is connected to the customer complaint hotspot data generation module, classifies the multiple customer complaint hotspots divided by the customer complaint hotspot data generation module according to the amount of customer complaints, including at least high customer complaint hotspots and low customer complaint hotspots, with the number of customer complaints in high customer complaint hotspots being greater than that in low customer complaint hotspots; and a grid area proportion calculation module, which is connected to the customer complaint hotspot data generation module, which uses data on the proportion of grid areas with signal strength less than a signal strength threshold in high customer complaint hotspots during a baseline time period and a comparison time period to calculate the average proportion of grid areas with signal strength less than a signal strength threshold in high customer complaint hotspots during the baseline time period. The system compares the average percentage of grid areas with signal strength below a signal strength threshold in high-complaint hotspot areas during a comparison period with the average percentage of grid areas with signal strength below a signal strength threshold in high-complaint hotspot areas during a baseline period, calculated by the grid area percentage calculation module. This comparison is then used to assess whether the improvement in signal strength in high-complaint hotspot areas has reached the improvement threshold. If the system determines that the improvement in signal strength in high-complaint hotspot areas has not reached the improvement threshold, further improvements can be made to the signal quality of those areas.

[0007] The signal quality improvement method for mobile network customer complaint hotspots described in this invention includes: a customer complaint hotspot data generation module dividing the service area of ​​the mobile network into multiple grid areas or multiple customer complaint hotspots; a customer complaint data processing module classifying the multiple customer complaint hotspots divided by the customer complaint hotspot data generation module into at least high customer complaint hotspots and low customer complaint hotspots based on the number of customer complaints, with the number of customer complaints in high customer complaint hotspots being greater than that in low customer complaint hotspots; and a grid area proportion calculation module using data on the proportion of grid areas with signal strength less than a signal strength threshold in high customer complaint hotspots during a baseline time period and a comparison time period to calculate the average proportion of grid areas with signal strength less than a signal strength threshold in high customer complaint hotspots during the baseline time period and the average proportion of grid areas with signal strength less than a signal strength threshold in high customer complaint hotspots during the comparison time period. The average percentage of grid areas where the signal strength of high customer complaint hotspots is less than the signal strength threshold; and the average percentage of grid areas where the signal strength of high customer complaint hotspots is less than the signal strength threshold during the baseline period, calculated by a customer complaint hotspot signal quality improvement assessment module using a grid area percentage calculation module, and the average percentage of grid areas where the signal strength of high customer complaint hotspots is less than the signal strength threshold during the comparison period, to assess whether the improvement effect of the signal strength of high customer complaint hotspots has reached the improvement threshold. This allows for further improvement of the signal quality of high customer complaint hotspots where the signal strength has not reached the improvement threshold when the customer complaint hotspot signal quality improvement assessment module determines that the improvement effect has not reached the improvement threshold.

[0008] The computer-readable medium of the present invention is applied in a computing device or computer, stores instructions, and is executed by a processor and memory, so as to perform the above-mentioned signal quality improvement method applied to the customer complaint hotspot of mobile network when the computer-readable medium is executed.

[0009] Therefore, this invention provides an innovative signal quality improvement system, method, and computer-readable medium for mobile network customer complaint hotspots. The system automatically divides the mobile network service area into multiple grid areas or multiple customer complaint hotspots using a customer complaint hotspot data generation module. This allows the customer complaint data processing module to efficiently classify the multiple customer complaint hotspots into at least high-complaint hotspots and low-complaint hotspots based on the volume of customer complaints, enabling rapid identification of areas with poor mobile network signal coverage (such as high-complaint hotspots), thereby improving the service quality of the mobile network.

[0010] Furthermore, the customer complaint hotspot signal quality improvement assessment module of the present invention utilizes the average proportion of grid areas with signal strength less than the signal strength threshold value in high customer complaint hotspots at different time points (such as the baseline period and the comparison period), as well as the improvement threshold value of high customer complaint hotspots, to facilitate accurate assessment of the improvement effect of the signal strength in high customer complaint hotspots.

[0011] In addition, the management terminal of this invention immediately improves the signal quality of the high customer complaint hotspots that have not reached the improvement threshold, so as to effectively maintain or improve the good experience of mobile network users.

[0012] To make the above-described features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings. Additional features and advantages of the invention will be set forth in part in the following description, and such features and advantages will be partly apparent from the description or may be learned by practice of the invention. It should be understood that both the foregoing general description and the following detailed description are illustrative and explanatory, and are not intended to limit the scope of the invention.

[0015] Figure 3 is a flowchart illustrating another embodiment of the signal quality improvement method for mobile network customer complaint hotspots described in this invention. Implementation

[0016] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can understand other advantages and effects of the present invention from the content disclosed in this specification, and can therefore implement or use it through other different specific equivalent embodiments.

[0017] Figure 1 is a schematic diagram of the architecture of the signal quality improvement system 1 applied to the customer complaint hotspot of mobile networks according to the present invention. As shown in Figure 1, the signal quality improvement system 1 applied to the customer complaint hotspot of mobile networks may include a customer complaint processing module 10, a customer complaint data interfacing module 20, a customer complaint data processing module 30, a customer complaint hotspot data generation module 40, a grid area proportion calculation module 50, a customer complaint hotspot signal quality improvement assessment module 60, at least one (or multiple) first data storage module 70, and at least one (or multiple) second data storage module 80, etc., and may also include at least one (or multiple) mobile network signal coverage grid data 90, etc.

[0018] In one embodiment, the customer complaint processing module 10 or the customer complaint data processing module 30 can be communicatively connected to the customer complaint data interface module 20, etc. The customer complaint hotspot data generation module 40 can be communicatively connected to the customer complaint data processing module 30, the grid area proportion calculation module 50 or the first data storage module 70, etc. The grid area proportion calculation module 50 can be further communicatively connected to the customer complaint hotspot signal quality improvement assessment module 60, the first data storage module 70, the second data storage module 80, etc. The customer complaint hotspot signal quality improvement assessment module 60 can be further communicatively connected to the second data storage module 80, etc.

[0019] In one embodiment, the customer complaint processing module 10 may be a customer complaint processor (chip / circuit), customer complaint processing software (program), etc.; the customer complaint data interface module 20 may be a data processing interface, customer complaint data interface component, customer complaint data interface software (program), etc.; the customer complaint data processing module 30 may be a customer complaint data processor (chip / circuit), customer complaint data processing software (program), etc.; the customer complaint hotspot data generation module 40 may be a customer complaint hotspot data generation component (chip / circuit), customer complaint hotspot data generation software (program), etc.; the grid area proportion calculation module 50 may be a customer complaint hotspot signal strength calculation and processing module, grid area proportion calculator (chip / circuit), grid area proportion calculation software (program), etc.; and the customer complaint hotspot signal quality improvement evaluation module 60 may be a customer complaint hotspot signal quality improvement evaluation component (chip / circuit), customer complaint hotspot signal quality improvement evaluation software (program), etc. The first data storage module 70 can be a customer complaint hotspot data storage module, etc., and the second data storage module 80 can be a customer complaint hotspot signal strength storage module, etc. However, the first data storage module 70 or the second data storage module 80 can also be a database, data storage device, data server, hard drive (such as cloud / network / external hard drive), memory, memory card, etc.

[0020] In one embodiment, the mobile network can be a fourth-generation (4G), fifth-generation (5G), sixth-generation (6G) or more advanced mobile network, the mobile communication device can be a mobile phone, tablet computer, smartwatch, etc., the management terminal 100 can be an administrator, management host, management server, management robot (such as an artificial intelligence robot), maintenance personnel, maintenance unit, etc., and the grid area can be the mobile network signal coverage grid, etc.

[0021] In this invention, "at least one" means one or more (e.g., one, two, or three or more), "plural" or "multiple" means two or more (e.g., two, three, four, or ten or more), and "communication connection" means mutual communication or connection through various forms such as data, signal, electrical, wired (e.g., wired network), or wireless (e.g., wireless network). However, this invention is not limited to those mentioned in the various embodiments.

[0022] In one embodiment, the customer complaint hotspot data generation module 40 can divide the service area of ​​the mobile network into multiple customer complaint hotspots. The customer complaint data processing module 30 then classifies these multiple hotspots based on the volume of customer complaints, including at least high customer complaint hotspots (HCC) and low customer complaint hotspots (LCC), with the number of customer complaints in high customer complaint hotspots (HCC) being greater than that in low customer complaint hotspots (LCC). Next, the grid area percentage calculation module 50 can use data from the baseline and comparison periods on the percentage 52 of grid areas where the signal strength of high customer complaint hotspots (HCC) is less than the signal strength threshold to calculate the average percentage 53 of grid areas where the signal strength of high customer complaint hotspots (HCC) is less than the signal strength threshold during the baseline period and the average percentage 53 of grid areas where the signal strength of high customer complaint hotspots (HCC) is less than the signal strength threshold during the comparison period. Then, the customer complaint hotspot signal quality improvement assessment module 60 can use the average percentage 53 of grid areas with signal strength less than the signal strength threshold value in the high customer complaint hotspot HCC during the baseline period, calculated by the grid area percentage calculation module 50, and the average percentage 53 of grid areas with signal strength less than the signal strength threshold value in the high customer complaint hotspot HCC during the comparison period, to assess whether the improvement effect of the customer complaint hotspot signal strength of the high customer complaint hotspot HCC has reached or not reached the improvement threshold value of the high customer complaint hotspot HCC. When the customer complaint hotspot signal quality improvement assessment module 60 determines that the improvement effect of the customer complaint hotspot signal strength of the high customer complaint hotspot HCC has not reached the improvement threshold value, the management terminal 100 will improve the signal quality of the high customer complaint hotspot HCC whose signal strength has not reached the improvement threshold value.

[0023] Therefore, the signal quality improvement system 1 for mobile network customer complaint hotspots described in this invention can quickly locate areas with poor mobile network signal coverage, quickly understand the status of mobile network signal in customer complaint hotspots, and effectively evaluate (confirm) the improvement effect of each customer complaint hotspot, and whether the improvement effect has reached (reached or not reached) the improvement threshold / improvement standard of mobile network signal in the customer complaint hotspot.

[0024] [1] Customer complaint handling module 10: can process customer complaint data 11 (such as customer complaint records) through the customer service terminal, and the customer service terminal can be customer service personnel, customer service software, customer service system, customer service platform, customer service robot, customer service center, etc.

[0025] [2] Customer complaint data interface module 20: can be a data processing interface, etc., used to interface with and obtain customer complaint data 11 (such as customer complaint records) processed by customer complaint processing module 10.

[0026] [3] Customer complaint data processing module 30: can process the customer complaint data 11 (such as customer complaint records) obtained by customer complaint data interface module 20, and customer complaint data processing module 30 can also classify the multiple customer complaint hot zones divided by customer complaint hot zone data generation module 40 according to the amount of customer complaints into at least high customer complaint hot zone HCC and low customer complaint hot zone LCC, for example, classified as high customer complaint hot zone HCC, medium customer complaint hot zone MCC (Medium Customer Complaint) and low customer complaint hot zone LCC. Then, customer complaint data processing module 30 stores the classified data that includes at least high customer complaint hot zone HCC and low customer complaint hot zone LCC (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and low customer complaint hot zone LCC) in the second data storage module 80.

[0027] The classification of multiple customer complaint hot zones (such as High Complaint Hot Zone HCC, Medium Complaint Hot Zone MCC, and / or Low Complaint Hot Zone LCC) is mainly used to quickly locate areas with poor mobile network signal coverage and to define improvement thresholds (or improvement standards) for different customer complaint hot zone categories. The more customer complaints a hot zone has, the higher its improvement threshold / standard can be set, while the fewer customer complaints a hot zone has, the lower its improvement threshold / standard can be set. For example, the improvement threshold / standard for the High Complaint Hot Zone HCC, which has the most customer complaints, can be higher than that for the Medium Complaint Hot Zone MCC, which has a moderate number of customer complaints, and the improvement threshold / standard for the Medium Complaint Hot Zone MCC, which has a moderate number of customer complaints, can be higher than that for the Low Complaint Hot Zone LCC, which has the fewest customer complaints.

[0028] [4] Customer Complaint Hotspot Data Generation Module 40: The service area of ​​the mobile network can be divided into multiple grid areas (such as small areas) and / or multiple customer complaint hotspots (for example, each customer complaint hotspot is 500M x 500M; M represents meters or meters), and the size of the grid areas can be the same or different from the size of the customer complaint hotspots. Furthermore, the customer complaint hotspot data generation module 40 generates customer complaint hotspot data 41 for each of the multiple customer complaint hotspots (such as high customer complaint hotspot HCC, medium customer complaint hotspot MCC and / or low customer complaint hotspot LCC), so that the customer complaint hotspot data 41 of the multiple customer complaint hotspots (such as high customer complaint hotspot HCC, medium customer complaint hotspot MCC and / or low customer complaint hotspot LCC) can be stored in the first data storage module 70 by the customer complaint hotspot data generation module 40.

[0029] [5] Grid area proportion calculation module 50: Based on the customer complaint hot zone data generation module 40 or the data storage module 70, the customer complaint hot zone data 41 of each of the multiple customer complaint hot zones (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) and at least one (such as multiple) mobile network signal coverage grid data 90 are generated to calculate the customer complaint hot zone signal strength 51 (such as reference signal received power) of each customer complaint hot zone (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC). The grid area percentage 52 where the power (RSRP) is less than the signal strength threshold (e.g., -100dBm; dBm represents decibels and milliwatts) is then calculated by the grid area percentage calculation module 50 and stores the data of the grid area percentage 52 of each customer complaint hot zone (e.g., high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) where the signal strength 51 (e.g., reference signal received power RSRP) is less than the signal strength threshold (e.g., RSRP < -100dBm) in the second data storage module 80.

[0030] [6] Customer Complaint Hot Zone Signal Quality Improvement Assessment Module 60: It can communicate with the second data storage module 80 to assess whether the improvement effect of the signal strength 51 (such as reference signal received power RSRP) of multiple customer complaint hot zones (such as high customer complaint hot zone HCC and / or medium customer complaint hot zone MCC) at different time points (such as the baseline period and the comparison period) has reached (reached or not reached) their respective improvement thresholds / improvement standards.

[0031] [7] First data storage module 70: can communicate with customer complaint hot zone data generation module 40 to store customer complaint hot zone data 41 of multiple customer complaint hot zones (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) generated by customer complaint hot zone data generation module 40.

[0032] [8] Second data storage module 80: can communicate with grid area proportion calculation module 50 to store data of grid area proportion 52 calculated by grid area proportion calculation module 50 for each customer complaint hot zone (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) whose customer complaint hot zone signal strength 51 (such as reference signal received power RSRP) is less than the signal strength threshold value (such as RSRP<-100dBm).

[0033] [9] Mobile network signal coverage grid data 90: The customer complaint hotspot data generation module 40 can divide the service area of ​​the mobile network into multiple grid areas (e.g., 10M x 10M; M represents meters or meters), and the mobile network signal coverage grid data 90 can include (store) the average value of the customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP) of each grid area. At the same time, the larger the value of the customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP), the better the signal quality of the customer complaint hotspot signal strength 51; conversely, the smaller the value of the customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP), the worse the signal quality of the customer complaint hotspot signal strength 51.

[0034] In one embodiment, a signal strength 51 (e.g., reference signal received power RSRP) in the customer complaint hotspot is less than a signal strength threshold (e.g., -100dBm) to indicate that the mobile network signal in the customer complaint hotspot is poor. The closer the value of the signal strength 51 (e.g., reference signal received power RSRP) in the customer complaint hotspot is to 0 (zero), the stronger or better the mobile network signal in the customer complaint hotspot.

[0035] In one embodiment, a customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP) equal to -80 dBm or higher (e.g., -70 dBm) indicates that the mobile network signal in the customer complaint hotspot is very good; a customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP) equal to between -90 dBm and -100 dBm indicates that the mobile network signal in the customer complaint hotspot is good; a customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP) equal to between -101 dBm and -110 dBm indicates that the mobile network signal in the customer complaint hotspot is normal; and a customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP) equal to -111 dBm or lower (e.g., -120 dBm) indicates that the mobile network signal in the customer complaint hotspot is poor or very poor.

[0036] Figure 2 is a flowchart illustrating one embodiment of the signal quality improvement method for mobile network customer complaint hotspots according to the present invention, and is also described with reference to the signal quality improvement system 1 for mobile network customer complaint hotspots shown in Figure 1.

[0037] [1] As shown in step S11 of Figures 1 and 2, calculate the customer complaint hotspot list (such as a list including high customer complaint hotspot HCC and / or medium customer complaint hotspot MCC). That is, the customer complaint hotspot data generation module 40 can divide the service area of ​​the mobile network into multiple grid areas (such as small areas) and / or multiple customer complaint hotspots (such as 500M x 500M), and then the customer complaint hotspot data generation module 40 stores the generated multiple customer complaint hotspot data (such as high customer complaint hotspot HCC, medium customer complaint hotspot MCC and / or low customer complaint hotspot LCC) customer complaint hotspot data 41 in the first data storage module 70.

[0038] [2] As shown in step S12 of Figures 1 and 2, the customer complaint hotspot classification is calculated. That is, the customer complaint data interface module 20 can obtain the customer complaint data 11 (such as customer complaint records) processed (recorded) by the customer complaint processing module 10 and the customer complaint hotspot data 41 stored in the first data storage module 70, so as to correspond the customer complaint data 11 with the customer complaint hotspot data 41. Then, the customer complaint data processing module 30 can classify multiple customer complaint hotspots according to the amount of customer complaints into at least high customer complaint hotspots HCC and low customer complaint hotspots LCC, for example, classifying them into high customer complaint hotspots HCC, medium customer complaint hotspots MCC and low customer complaint hotspots LCC, and then the customer complaint data processing module 30 stores the classified data that at least includes high customer complaint hotspots HCC and low customer complaint hotspots LCC (such as high customer complaint hotspots HCC, medium customer complaint hotspots MCC and low customer complaint hotspots LCC) in the second data storage module 80.

[0039] [3] As shown in step S13 of Figures 1 and 2, calculate the proportion of grid areas where the signal strength 51 (e.g., the reference signal received power RSRP) of the customer complaint hot zone is less than the signal strength threshold value (e.g., -100dBm) 52.

[0040] The signal quality improvement system 1 applied to mobile network customer complaint hotspots may include mobile network signal coverage grid data 90, and the customer complaint hotspot data generation module 40 can divide the service area of ​​the mobile network into multiple grid areas (e.g., 10M x 10M). Simultaneously, the larger the value of the customer complaint hotspot signal strength 51 (e.g., Reference Signal Received Power RSRP), the better the signal quality of the customer complaint hotspot signal strength 51; conversely, the smaller the value of the customer complaint hotspot signal strength 51 (e.g., Reference Signal Received Power RSRP), the worse the signal quality of the customer complaint hotspot signal strength 51.

[0041] The grid area proportion calculation module 50 can calculate the customer complaint hotspot data 41 of each of the multiple customer complaint hotspots (such as high customer complaint hotspot HCC, medium customer complaint hotspot MCC, and / or low customer complaint hotspot LCC) and at least one (such as multiple) mobile network signal coverage grid data 90 based on the customer complaint hotspot data generation module 40 or the first data storage module 70, to calculate the customer complaint hotspot signal strength 51 of each customer complaint hotspot (such as high customer complaint hotspot HCC, medium customer complaint hotspot MCC, and / or low customer complaint hotspot LCC) (as reference). The grid area percentage 52 where the signal received power (RSRP) is less than the signal strength threshold (e.g., RSRP < -100dBm) is then calculated by the grid area percentage calculation module 50 and stores the data of the grid area percentage 52 where the signal strength 51 (e.g., reference signal received power RSRP) of each customer complaint hot zone (e.g., high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) is less than the signal strength threshold (e.g., RSRP < -100dBm) in the second data storage module 80.

[0042] [4] As shown in step S14 of Figures 1 and 2, the improvement effect of the customer complaint hot zone signal strength 51 (such as reference signal received power RSRP) of the customer complaint hot zone (such as high customer complaint hot zone HCC and / or medium customer complaint hot zone MCC) is evaluated. That is, the customer complaint hot zone signal quality improvement evaluation module 60 can be communicatively connected to the second data storage module 80 so that the customer complaint hot zone signal quality improvement evaluation module 60 can evaluate whether the improvement effect of the customer complaint hot zone signal strength 51 (such as reference signal received power RSRP) of multiple customer complaint hot zones (such as high customer complaint hot zone HCC and / or medium customer complaint hot zone MCC) at different time points (such as the baseline time period and the comparison time period) has reached (reached or not reached) their respective improvement threshold values / improvement standards.

[0043] Figure 3 is a flowchart illustrating another embodiment of the signal quality improvement method for mobile network customer complaint hotspots according to the present invention, and is described in conjunction with the signal quality improvement system 1 for mobile network customer complaint hotspots described in Figure 1.

[0044] [1] As shown in step S21 of Figures 1 and 3, the improvement threshold / standard for the customer complaint hot zone category is set. That is, the management terminal 100 (such as the administrator / maintenance unit) can set the improvement threshold for multiple customer complaint hot zone categories (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC or low customer complaint hot zone LCC) to assess whether the improvement threshold / standard for mobile network signal has been met (met or not met).

[0045] [2] As shown in steps S22 to S23 of Figures 1 and 3, the baseline period and the comparison period are set respectively to obtain the data of the percentage of grid areas with signal strength less than the signal strength threshold (e.g., RSRP<-100dBm) in the customer complaint hot area during the baseline period (e.g., daily) and the data of the percentage of grid areas with signal strength less than the signal strength threshold (RSRP<-100dBm) in the customer complaint hot area during the comparison period (e.g., daily). That is, the management terminal 100 (such as the administrator / maintenance unit) can set the evaluation (comparison) time points, including different baseline time periods and comparison time periods. Both the baseline time period and the comparison time period can be a time interval (such as 1 day, 1 week, 1 month, etc.). Through the settings of the management terminal 100 (such as the administrator / maintenance unit), the data of the percentage of grid areas with signal strength 51 (such as reference signal received power RSRP) less than the signal strength threshold value (such as RSRP<-100dBm) in each customer complaint hot zone (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) during the baseline time period and comparison time period can be obtained (such as a list of data of grid area percentage 52).

[0046] [3] As shown in step S24 of Figures 1 and 3, the customer complaint hot zone category is marked. That is, the grid area proportion calculation module 50 can use the customer complaint hot zone marking to mark the current customer complaint hot zone category of the reference period as belonging to the high customer complaint hot zone HCC or the low customer complaint hot zone LCC, or the medium customer complaint hot zone MCC (if any) according to the previous customer complaint hot zone classification (as shown in step S12 of Figure 2).

[0047] [4] As shown in steps S25 to S26 of Figures 1 and 3, the grid area proportion calculation module 50 uses the customer complaint data of the customer complaint hot zones (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) classified by the customer complaint data processing module 30, to calculate the customer complaint hot zone signal strength 51 (such as reference signal received power RSRP) of each customer complaint hot zone (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) less than the signal strength threshold value (such as RSRP < -100dBm) of each customer complaint hot zone (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) in the reference time period (such as reference signal received power ... The average percentage of grid areas with RSRP less than the signal strength threshold (e.g., RSRP < -100dBm) is calculated, and the average percentage of grid areas with RSRP less than the signal strength threshold (e.g., RSRP < -100dBm) in each customer complaint hot zone (e.g., high customer complaint hot zone HCC, medium customer complaint hot zone MCC, and / or low customer complaint hot zone LCC) during the comparison period is also calculated. This is used to represent or quickly understand the mobile network signal status of each customer complaint hot zone (e.g., high customer complaint hot zone HCC, medium customer complaint hot zone MCC, and / or low customer complaint hot zone LCC).

[0048] [5] As shown in step S27 of Figures 1 and 3, is the improvement effect of the customer hot zone signal strength 51 (such as reference signal received power RSRP) of the customer hot zone evaluated to see if it has reached (reached or not reached) the improvement threshold value? That is, the customer hot zone signal quality improvement evaluation module 60 can evaluate (confirm) whether the improvement effect of the customer hot zone signal strength 51 (mobile network signal) of multiple customer hot zones has reached (reached or not reached) their respective improvement threshold value / improvement standard. Then, the management terminal 100 (such as the administrator / maintenance unit) to which the customer complaint hotspot belongs can query the system or send a notification to the management terminal 100 for the list of customer complaint hotspots that have not met the improvement threshold / improvement standard (such as a list including high customer complaint hotspots HCC and / or medium customer complaint hotspots MCC). The management terminal 100 can then immediately improve the signal quality of the customer complaint hotspot signal strength 51 (such as reference signal received power RSRP) of the customer complaint hotspots that have not met the improvement threshold / improvement standard (such as high customer complaint hotspots HCC and / or medium customer complaint hotspots MCC), thereby effectively maintaining or improving the good experience of mobile network users.

[0049] For example, the technical content of the signal quality improvement system 1 and method for mobile network customer complaint hotspots as shown in Figures 1 and 2 is further explained below.

[0050] [1] As shown in step S11 of Figures 1 and 2, calculate the customer complaint hotspot list (such as a list including high customer complaint hotspot HCC and / or medium customer complaint hotspot MCC). That is, the customer complaint hotspot data generation module 40 can divide the service area of ​​the mobile network into multiple grid areas (such as small areas) and / or multiple customer complaint hotspots (such as 500M x 500M), and then the customer complaint hotspot data generation module 40 stores the generated multiple customer complaint hotspot data (such as high customer complaint hotspot HCC, medium customer complaint hotspot MCC and / or low customer complaint hotspot LCC) customer complaint hotspot data 41 in the first data storage module 70, and the customer complaint hotspot data 41 may include customer complaint hotspot number and other information.

[0051] [2] As shown in step S12 of Figures 1 and 2, the customer complaint hotspot classification is calculated. That is, the customer complaint data interface module 20 can obtain the customer complaint data 11 recorded by the customer complaint processing module 10 and the customer complaint hotspot data 41 stored by the first data storage module 70, so as to correspond the customer complaint data 11 with the customer complaint hotspot data 41. Then, the customer complaint data processing module 30 can classify the multiple customer complaint hotspots according to the amount of customer complaints into at least high customer complaint hotspots HCC and low customer complaint hotspots LCC (such as high customer complaint hotspots HCC, medium customer complaint hotspots MCC and low customer complaint hotspots LCC).

[0052] Then, as shown in Table 1 below, the customer complaint data processing module 30 can store the classified data, including at least the high customer complaint hot zone HCC and the low customer complaint hot zone LCC (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and low customer complaint hot zone LCC), in the second data storage module 80.

[0053] Table 1: Data on high-complaint hotspots (HCC), medium-complaint hotspots (MCC), etc., which may include date, hotspot category, hotspot number, etc.

[0054]

[0055] In one embodiment, the number of complaints in the high complaint hotspot (HCC) is greater than the number of complaints in the low complaint hotspot (LCC). For example, the system (such as the signal quality improvement system 1 used for mobile network complaint hotspots) or the management terminal 100 (such as the administrator / maintenance unit) can set a complaint volume threshold value, so that the complaint data processing module 30 can classify the plurality of complaint hotspots into high complaint hotspots (HCC) and low complaint hotspots (LCC) according to the complaint volume threshold value, wherein the number of complaints in the high complaint hotspot (HCC) is greater than the complaint volume threshold value, and the number of complaints in the low complaint hotspot (LCC) is less than the complaint volume threshold value.

[0056] In another embodiment, the number of complaints in the high-complaint hot zone (HCC) is greater than that in the medium-complaint hot zone (MCC), and the number of complaints in the medium-complaint hot zone (MCC) is greater than that in the low-complaint hot zone (LCC). For example, the system (such as the signal quality improvement system 1 used in mobile network complaint hot zones) or the management terminal 100 (such as the administrator / maintenance unit) can set a first complaint volume threshold and a second complaint volume threshold, so that the complaint data processing module 30 can classify the plurality of complaint hot zones into high-complaint hot zones (HCC), medium-complaint hot zones (MCC), and low-complaint hot zones (LCC) according to the first and second complaint volume thresholds. The number of complaints in the high-complaint hot zone (HCC) is greater than the first complaint volume threshold, the number of complaints in the medium-complaint hot zone (MCC) is between the first and second complaint volume thresholds, and the number of complaints in the low-complaint hot zone (LCC) is less than the second complaint volume threshold.

[0057] [3] As shown in step S13 of Figures 1 and 2, calculate the proportion of grid areas 52 where the signal strength 51 (e.g., the reference signal received power RSRP) of the customer complaint hot zone is less than the signal strength threshold value (e.g., RSRP < -100dBm).

[0058] The signal quality improvement system 1 applied to mobile network customer complaint hotspots may include mobile network signal coverage grid data 90, and the customer complaint hotspot data generation module 40 may divide the service area of ​​the mobile network into multiple grid areas (e.g., 10M x 10M). Furthermore, the grid area proportion calculation module 50 may calculate the proportion 52 of each customer complaint hotspot (e.g., high customer complaint hotspot HCC, medium customer complaint hotspot MCC, and / or low customer complaint hotspot LCC) whose customer complaint hotspot signal strength 51 (e.g., reference signal received power RSRP) is less than the signal strength threshold value (e.g., RSRP < -100dBm) based on the customer complaint hotspot data 41 generated by the customer complaint hotspot data generation module 40 or stored by the first data storage module 70.

[0059] Then, as shown in Table 2 below, the grid area proportion calculation module 50 can store the data of the grid area proportion 52 of each customer complaint hot zone (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) whose customer complaint hot zone signal strength 51 (such as reference signal received power RSRP) is less than the signal strength threshold value (such as RSRP<-100dBm) in the second data storage module 80.

[0060] Table 2: Data on the percentage of grid areas with signal strength less than the signal strength threshold (e.g., RSRP < -100dBm) in each customer complaint hot zone (e.g., high customer complaint hot zone HCC and / or medium customer complaint hot zone MCC).

[0061]

[0062] For example, the technical content of the signal quality improvement system 1 and method for mobile network customer complaint hotspots described in Figures 1 and 3 of the present invention will be further explained below.

[0063] [1] As shown in step S21 of Figures 1 and 3, the management terminal 100 (e.g., the administrator / maintenance unit) sets different improvement thresholds / standards for the signal strength 51 (e.g., reference signal received power RSRP) of each customer complaint hot zone (e.g., high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC). For example: (a) The improvement threshold / standard for the high customer complaint hot zone HCC is set as follows: to reduce poor coverage, the proportion of grid areas with a signal strength 51 (e.g., reference signal received power RSRP) less than the signal strength threshold (e.g., RSRP<-100dBm) should be reduced by at least the first proportion (e.g., 10%) of the grid area proportion 52. (b) The improvement threshold / standard for medium-complaint hot zones (MCC) is set as follows: the proportion of grid areas with a signal strength 51 (e.g., reference signal received power RSRP) less than the signal strength threshold (e.g., RSRP < -100dBm) in the customer complaint hot zone 52 must be reduced by at least the second proportion (e.g., 5%), and the first proportion (e.g., 10%) must be greater than the second proportion (e.g., 5%). (c) The improvement threshold / standard for low-complaint hot zones (LCC) is set as follows: no improvement is required (no action is needed).

[0064] [2] As shown in steps S22 to S23 of Figures 1 and 3, the management terminal 100 (such as the manager / maintenance unit) sets the data of the proportion of grid areas whose customer complaint hot zones (such as high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) have a signal strength 51 (such as reference signal received power RSRP) less than the signal strength threshold value (such as RSRP<-100dBm) in the reference time period and the comparison time period. For example, the reference time period is the first time period and the comparison time period is the second time period, which is different from the first time period.

[0065] [3] As shown in step S24 of Figures 1 and 3, the customer complaint hot zone category is marked. That is, the grid area proportion calculation module 50 can set the customer complaint hot zone mark based on the data of the grid area proportion 52 where the customer complaint hot zone signal strength 51 (e.g., reference signal received power RSRP) of each customer complaint hot zone (e.g., high customer complaint hot zone HCC, medium customer complaint hot zone MCC and / or low customer complaint hot zone LCC) is less than the signal strength threshold value (e.g., RSRP<-100dBm). This is so that when evaluating the improvement effect of the customer complaint hot zone signal strength 51 (e.g., RSRP) in the subsequent evaluation, it can correspond and compare with the improvement threshold value / improvement standard set in step S21 above.

[0066] Taking customer complaint hotspot number 225 in Tables 1 and 2 above as an example, the customer complaint hotspot category marked by customer complaint hotspot number 225 is a high customer complaint hotspot HCC. Therefore, the high customer complaint hotspot HCC of customer complaint hotspot number 225 can correspond to the improvement threshold / improvement standard of the customer complaint hotspot category (such as high customer complaint hotspot HCC or its customer complaint hotspot signal) set in step S21 above: "The improvement threshold / improvement standard of high customer complaint hotspot HCC is set as follows: reduce the coverage of poor areas, and reduce the proportion of grid areas with customer complaint hotspot signal strength 51 (such as reference signal received power RSRP) less than the signal strength threshold value (such as RSRP<-100dBm) by at least the first proportion (such as 10%) of the grid area proportion 52".

[0067] [4] As shown in steps S25 to S26 of Figures 1 and 3, the grid area proportion calculation module 50 can calculate the average proportion 53 of the grid areas whose customer complaint hot zones (such as high customer complaint hot zone HCC and / or medium customer complaint hot zone MCC) have a signal strength 51 (such as reference signal received power RSRP) less than the signal strength threshold value (such as RSRP<-100dBm) during the reference time period (such as the first time period) and the comparison time period (such as the second time period).

[0068] (a) Customer Complaint Hotspot No. 225: As shown in Table 3 below, the grid area percentage calculation module 50 can calculate the average percentage (unit: %) of the grid areas with a high customer complaint hotspot HCC of customer complaint hotspot No. 225 whose signal strength 51 (e.g., reference signal received power RSRP) is less than the signal strength threshold value (e.g., RSRP < -100dBm) during the "baseline period". Simultaneously, the grid area percentage calculation module 50 can also calculate the average percentage (unit: %) of the grid areas with a high customer complaint hotspot HCC of customer complaint hotspot No. 225 whose signal strength 51 (e.g., reference signal received power RSRP) is less than the signal strength threshold value (e.g., RSRP < -100dBm) during the "comparison period".

[0069] Table 3: High-Complaint Hotspot Areas (HCC), Complaint Hotspot Number 225

[0070] (b) Customer Complaint Hotspot No. 282: As shown in Table 4 below, the grid area percentage calculation module 50 can calculate the average percentage (unit: %) of grid areas in Customer Complaint Hotspot No. 282 where the signal strength 51 (e.g., reference signal received power RSRP) of the customer complaint hotspot MCC is less than the signal strength threshold value (e.g., RSRP < -100dBm). Simultaneously, the grid area percentage calculation module 50 can also calculate the average percentage (unit: %) of grid areas in Customer Complaint Hotspot No. 282 where the signal strength 51 (e.g., reference signal received power RSRP) of the customer complaint hotspot MCC is less than the signal strength threshold value (e.g., RSRP < -100dBm).

[0071] Table 4: MCCs of Customer Complaint Hotspots, Customer Complaint Hotspot Number 282

[0072] (c) Customer Complaint Hotspot No. 242: As shown in Table 5 below, the grid area percentage calculation module 50 can calculate the average percentage (unit: %) of the grid areas with a high customer complaint hotspot HCC of customer complaint hotspot No. 242 whose signal strength 51 (e.g., reference signal received power RSRP) is less than the signal strength threshold value (e.g., RSRP < -100dBm) during the "baseline period". Simultaneously, the grid area percentage calculation module 50 can also calculate the average percentage (unit: %) of the grid areas with a high customer complaint hotspot HCC of customer complaint hotspot No. 242 whose signal strength 51 (e.g., reference signal received power RSRP) is less than the signal strength threshold value (e.g., RSRP < -100dBm) during the "comparison period".

[0073] Table 5: High-Complaint Hotspot Areas (HCC), Complaint Hotspot Number 242

[0074] [5] As shown in step S27 of Figures 1 and 3, the customer complaint hot zone signal quality improvement assessment module 60 can assess whether the improvement effect of the customer complaint hot zone signal strength 51 (such as reference signal received power RSRP) of each customer complaint hot zone (such as high customer complaint hot zone HCC and / or medium customer complaint hot zone MCC) has reached (reached or not reached) the improvement threshold value?

[0075] For example, this improvement effect can be calculated as the difference between "the average percentage of grid areas with a signal strength 51 (e.g., reference signal received power RSRP) less than a signal strength threshold (e.g., RSRP < -100dBm) in the customer complaint hotspot during the baseline period (53%)" and "the average percentage of grid areas with a signal strength 51 (e.g., reference signal received power RSRP) less than a signal strength threshold (e.g., RSRP < -100dBm) in the customer complaint hotspot during the comparison period (53%)". If this difference is greater than the set improvement threshold, it means that the improvement effect of the signal strength 51 (e.g., reference signal received power RSRP) in the customer complaint hotspot (e.g., high customer complaint hotspot HCC and / or medium customer complaint hotspot MCC) has met the improvement target (the improvement threshold / improvement standard has been reached). Conversely, if this difference is not greater than (e.g. equal to or less than) the set improvement threshold, it means that the improvement effect of the customer complaint hot zone signal strength 51 (e.g. reference signal received power RSRP) of the customer complaint hot zone (e.g., high customer complaint hot zone HCC and / or medium customer complaint hot zone MCC) is not improved (not meeting the improvement threshold / improvement standard).

[0076] As shown in Table 6 below, for the list of customer complaint hotspots that do not meet the improvement threshold / improvement standards (such as the high customer complaint hotspot HCC with customer complaint hotspot number 242), the management terminal 100 to which the customer complaint hotspot belongs (such as the administrator / maintenance unit) can query through the system or the system can actively send a notification to the management terminal 100, so that the maintenance unit can improve the signal quality of the customer complaint hotspot signal strength 51 (such as the reference signal received power RSRP) of the customer complaint hotspots that do not meet the improvement threshold / improvement standards (such as the high customer complaint hotspot HCC and / or the medium customer complaint hotspot MCC), thereby effectively maintaining or improving the good experience of mobile network users.

[0077] Table 6: Improvement effectiveness of customer complaint hotspot signal strength 51 (e.g., RSRP < -100dBm). For example, in the "Improvement achieved" column, 10% is the improvement threshold / standard for high customer complaint hotspot HCC, and 5% is the improvement threshold / standard for medium customer complaint hotspot MCC.

[0078] Furthermore, the present invention provides a computer-readable medium for a signal quality improvement method applied to a mobile network customer complaint hotspot. This medium is used in a computing device or computer having a processor and memory. The computer-readable medium stores instructions, which can be executed by the computing device or computer through the processor and memory. When the computer-readable medium is executed, the content of the aforementioned signal quality improvement method for a mobile network customer complaint hotspot is performed. In another embodiment, this computer-readable medium is a non-transitory computer-readable storage medium.

[0079] In one embodiment, the processor may be a central processing unit (CPU), graphics processing unit (GPU), microprocessor (MPU), microcontroller (MCU), artificial intelligence (AI) processor, etc., and the memory may be random access memory (RAM), read-only memory (ROM), flash memory, memory card, hard disk (such as cloud / network / external hard disk), optical disk, USB flash drive, database, etc., and the computing device or computer may be a computer, smartphone, tablet computer, personal computer, notebook computer, desktop computer, server (such as cloud / remote / network / AI server), etc.

[0080] In one embodiment, the modules can be software, hardware, or firmware; if they are hardware, they can be processing units, processors, computers, or servers with data processing and computing capabilities; if they are software or firmware, they can include instructions executable by processing units, processors, computers, or servers, and can be installed on the same hardware device or distributed across different multiple hardware devices.

[0081] In summary, the signal quality improvement system, method, and computer-readable medium system for mobile network customer complaint hotspots described in this invention have at least the following features, advantages, or technical effects.

[0082] I. This invention can quickly locate areas with poor mobile network signal coverage, thereby improving the service quality of mobile networks. Specifically, the customer complaint hotspot data generation module 40 of this invention can automatically divide the service area of ​​the mobile network into multiple customer complaint hotspots (e.g., 500M x 500M), efficiently classifying these hotspots based on the volume of customer complaints (e.g., high complaint hotspot HCC, medium complaint hotspot MCC, and / or low complaint hotspot LCC), and thus quickly identifying areas with poor mobile network signal coverage (e.g., high complaint hotspot HCC and / or medium complaint hotspot MCC).

[0083] Second, this invention can quickly locate areas with poor mobile network signal coverage by classifying high-complaint hot zones (HCC) and / or medium-complaint hot zones (MCC), and prioritize these areas for improvement. It can also analyze the signal strength 51 (e.g., Reference Signal Received Power (RSRP)) values ​​of customer complaint hot zones in each mobile network signal coverage grid (e.g., each grid is 10M x 10M) to quickly understand the mobile network signal status of each hot zone, thereby accurately assessing the improvement effectiveness of the signal strength 51 (e.g., Reference Signal Received Power (RSRP)) in multiple customer complaint hot zones (e.g., high-complaint hot zones (HCC) and / or medium-complaint hot zones (MCC)).

[0084] 3. The customer complaint hotspot data generation module 40 of the present invention can divide the service area of ​​the mobile network into multiple customer complaint hotspots (such as 500M x 500M), so that the customer complaint data processing module 30 can classify the multiple customer complaint hotspots according to the amount of customer complaints into at least high customer complaint hotspots (HCC) and low customer complaint hotspots (LCC); for example, (1) classifying them into both high customer complaint hotspots (HCC) and low customer complaint hotspots (LCC), or (2) classifying them into three categories: high customer complaint hotspots (HCC), medium customer complaint hotspots (MCC), and low customer complaint hotspots (LCC), so as to efficiently determine the areas with poor mobile network signal coverage (such as high customer complaint hotspots (HCC) and / or medium customer complaint hotspots (MCC)).

[0085] Fourth, the grid area proportion calculation module 50 of the present invention can quickly understand the status of mobile network signal in the customer complaint hot zone. That is, the grid area proportion calculation module 50 can calculate the proportion 52 of the grid area where the signal strength 51 (such as the reference signal received power RSRP) of each customer complaint hot zone is less than the signal strength threshold value (such as RSRP < -100dBm), so as to facilitate the accurate assessment of the coverage of mobile network signal.

[0086] V. The customer complaint hotspot signal quality improvement assessment module 60 of the present invention can assess the improvement effect of the signal strength 51 (such as reference signal received power RSRP) of multiple customer complaint hotspots (such as high customer complaint hotspot HCC and / or medium customer complaint hotspot MCC). That is, based on the average proportion 53 of the grid area where the signal strength 51 (such as reference signal received power RSRP) of multiple customer complaint hotspots (such as high customer complaint hotspot HCC, medium customer complaint hotspot MCC and / or low customer complaint hotspot LCC) is less than the signal strength threshold value (such as RSRP<-100dBm) at different time points (such as the baseline period and the comparison period), and the set improvement threshold value / improvement standard, so as to accurately assess the improvement effect of multiple customer complaint hotspots (such as high customer complaint hotspot HCC and / or medium customer complaint hotspot MCC), thereby effectively maintaining or improving the good experience of mobile network users.

[0087] VI. The customer complaint hotspot signal quality improvement assessment module 60 of this invention can utilize the signal strength 51 (e.g., reference signal received power RSRP) of multiple customer complaint hotspots (e.g., high customer complaint hotspot HCC, medium customer complaint hotspot MCC, and / or low customer complaint hotspot LCC) at different time points (e.g., baseline period and comparison period) of the grid area proportion 52 (average grid area proportion 53) less than the signal strength threshold value (e.g., RSRP < -100dBm), and use the management terminal 100 ( If the administrator / maintenance unit sets different improvement thresholds / standards for at least high customer complaint hot zones (HCC) and low customer complaint hot zones (LCC) (such as high customer complaint hot zones (HCC), medium customer complaint hot zones (MCC), and low customer complaint hot zones (LCC), it will be helpful to accurately evaluate the improvement effect of the signal strength 51 (such as reference signal received power (RSRP)) of multiple customer complaint hot zones (such as high customer complaint hot zones (HCC) and / or medium customer complaint hot zones (MCC)), thereby effectively maintaining or improving the good experience of mobile network users.

[0088] VII. This invention can estimate the signal strength 51 (e.g., reference signal received power RSRP) of the customer complaint hot zone by using the signal strength 51 of the customer complaint hot zone (e.g., 10M x 10M) transmitted back to the base station by a mobile communication device (e.g., a mobile communication device with a Subscriber Identity Module Card (SIM card)) to the base station. It also calculates the percentage 52 of the grid area within each customer complaint hot zone where the signal strength 51 (e.g., reference signal received power RSRP) is less than the signal strength threshold value (e.g., RSRP < -100dBm), so as to facilitate a rapid understanding of the mobile network signal status of the customer complaint hot zone.

[0089] The above embodiments are merely illustrative of the principles, features, and effects of the present invention and are not intended to limit the scope of implementation of the present invention. Anyone skilled in the art can modify and alter the above embodiments without departing from the spirit and scope of the present invention. Any equivalent changes and modifications made using the content disclosed in this invention should still be covered by the claims.
