[0016] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Please see Figure 1This invention discloses an automated testing and maintenance management system for mobile network signals, which improves data acquisition efficiency, enables visualized presentation and alarm monitoring of mobile network signal quality, and allows for automatic filling of work order information for efficient operation and maintenance. Specifically, the maintenance management system in this embodiment includes a data acquisition module 100 deployed on a mobile terminal, and a data analysis module 200, a network quality visualization module 300, a network monitoring and alarm module 400, a user complaint handling module 500, a test task and work order management module 600, and a report module 700 deployed in the background. The data acquisition module 100 is used to periodically collect signal data from the mobile terminal. The data analysis module 200 is used to receive and analyze the signal data sent by the data acquisition module 100 to evaluate the mobile network signal quality and display relevant parameters of the mobile network signal, facilitating maintenance personnel's understanding of the mobile network situation. The network quality visualization module 300 is used to receive the signal data analysis results and display the signal quality on a map, allowing maintenance personnel to intuitively understand the network quality in each area, facilitating timely response and handling of network anomalies and faults, achieving a global understanding of network quality and accurate location of abnormal networks. The network monitoring and alarm module 400 issues alarms and generates alarm work orders when signal data analysis results are abnormal. This allows maintenance personnel to handle faulty networks within a designated area based on the alarm work orders, enabling targeted troubleshooting and preventing the omission of areas with abnormal mobile network signals. The user complaint handling module 500 receives complaint data and generates complaint work orders. It associates frontline signal test data with complaint work orders and automatically fills out return forms, thus automating complaint work order filling, reducing the workload of maintenance personnel, and avoiding data entry errors caused by manual filling. The test task and work order management module 600 sets up test areas or routes, creates test plans and dispatches test tasks, receives test results, alarm work orders, and complaint work orders, and dispatches work orders to maintenance personnel. The reporting module 700 categorizes and statistically analyzes signal quality and generates reports, allowing maintenance personnel to comprehensively understand various indicators of mobile network signals and providing a basis for mobile network management and optimization.

[0018] The aforementioned automated mobile network signal testing and display operation and maintenance management system periodically collects signal data from mobile terminals through the data acquisition module 100, which is then analyzed by the data analysis module 200. This enables automated, seamless testing of signal data, reducing manual testing workload and improving the efficiency of mobile network signal data collection. By visualizing the collected signal data on a map and automatically dispatching alarm work orders based on signal quality, the system achieves visualized display of mobile network signal quality and alarm monitoring. The user complaint processing module 500 receives complaint data and generates complaint work orders, enabling automatic correlation and reporting of complaint work order maintenance and work order and test data. This operation and maintenance management system requires minimal manual intervention during complaint work order maintenance, can handle large-scale data monitoring, and achieves efficient operation and maintenance of mobile network signals.

[0019] In one embodiment, the signal data includes signal location data and signal indicator data. The signal indicator data includes at least the reference received power (RSRP) and the signal-to-interference-plus-noise ratio (SINR). Thus, the data acquisition module 100 uploads signal location data while reporting the signal indicator data, so as to locate the mobile terminal and facilitate the rapid network location of the abnormal or complained location when the mobile network signal is abnormal or a user complains.

[0020] It should be noted that in this embodiment, the mobile terminal is loaded with a MobileNetCloudTest APP capable of manual or automatic signal data acquisition, a third-party professional network testing tool capable of manual data upload, and a port bound to the customer service system (the official customer service hotline platform of the broadcasting company) for data connection. The data collected by the data acquisition module 100 deployed on the mobile terminal (such as a mobile phone equipped with a 5G SIM card) comes from the above three sources. That is to say, the data acquisition module 100 can obtain signal data from the mobile terminal, and also obtain complaint data from the mobile terminal and forward it to the user complaint processing module 500. Specifically, the data collected by the data acquisition module 100 from the customer service system is the complaint data issued by the user, so that the user complaint processing module 500 can generate corresponding complaint work orders and dispatch them to maintenance personnel for processing. The data acquisition module 100 manually imports data collected via third-party professional network testing tools, which is then used as third-party testing software data. This enables the uploading of raw data and test results for various service indicators, including 5G data services, 4G data services, VoNR (Voice over New Radio), EPSFB (Evolved Packet System Fallback), and VoLTE (Voice over LTE), providing analytical support for the data analysis module 200. The data acquired by the data acquisition module 100 through the Mobile Network Cloud Testing APP constitutes mobile communication network service indicators. These indicators include basic information, LTE serving cell information, NR serving cell information, LTE network indicators, and NR network indicators. The basic information is the signal positioning data for this solution; the LTE serving cell information, NR serving cell information, LTE network indicators, and NR network indicators together form the signal indicator data for this solution. The basic information includes the mobile operating system version, terminal model, operator, latitude and longitude, and geographical location information. LTE (Long-Term Evolution, for 4G networks) serving cell information includes serving cell data network type (LTE), cell type (LTE), tracking area code (TAC), physical cell identifier (PCI), cell identity identifier (ECI), signal width (BAND WIDTH), absolute carrier frequency signal (EARFCN), frequency (FREQ), and frequency band (BAND).NR (New Radio, for 5G networks) serving cell information includes: serving cell data network type (NR), cell type (NR), NR tracking area code (NR-TAC), NR physical cell identifier (NR-PCI), NR cell identity identifier (NR-CI), NR radio channel code, NR frequency (NR-FREQ), NR band (NR-BAND), NR location area identifier (LAC), and NR service scrambling code (PSC). LTE network metrics include RSRP (Reference Received Power), SINR (Signal-to-Interference-plus-Noise Ratio), RSRQ (Reference Received Quality), and RSSI (Received Signal Strength Indication) metrics for the serving cell and neighboring serving cells. NR network metrics are SS-RSRP (Received Power Measured Based on 5G Base Station Synchronization Block), SS-SINR (Signal-to-Interference-plus-Noise Ratio Measured Based on 5G Base Station Synchronization Block), and SS-RSRQ (Reference Received Quality Measured Based on 5G Base Station Synchronization Block) metrics for the serving cell and neighboring serving cells.

[0021] Additionally, it should be noted that the data acquisition module 100 collects data in two ways: manually and automatically. The manual data acquisition method is only for third-party professional network testing tools. These tools copy the original test data and perform data parsing to obtain the business indicator test analysis results. The data acquisition module 100 then imports the files into the system for analysis by the data analysis module 200. The automatic data acquisition method is implemented by the MobileNetCloudTest APP to achieve automatic data collection and uploading. In this embodiment, the daily operation and maintenance of the operation and maintenance management system is implemented by the MobileNetCloudTest APP. The data acquisition module 100 can be an algorithm or program of the MobileNetCloudTest APP. Alternatively, the data acquisition module 100 can be an algorithm or program independent of the MobileNetCloudTest APP but associated with it, to achieve automatic collection of signal data. Furthermore, the data acquisition module 100 is also used to receive external instructions in dedicated testing mode and retest areas with abnormal signal data.

[0022] The data analysis module 200 analyzes and processes the data uploaded by the data acquisition module 100, and sends the analysis results to the network quality visualization module 300, the network monitoring and alarm module 400, the user complaint handling module 500, and the reporting module 700. Each module then performs corresponding actions based on the data analysis results. Specifically, the data analysis module 200 has preset signal indicator thresholds. It compares the received signal indicator data with these thresholds, classifies the data according to the comparison results, and the network quality visualization module 300 uses different colors to distinguish different quality levels of signal indicator data on a map. Further, the data analysis module 200 categorizes the signal indicator data into normal and substandard data based on the comparison results. The network quality visualization module 300 then displays the substandard data areas on the map using color; the network monitoring and alarm module 400 generates alarm work orders for the substandard data areas. In this embodiment, the RSRP (Reference Signal Received Power) value is used as an example to illustrate the signal indicator data analysis process. Specifically, the data analysis module 200 sets the RSRP signal indicator threshold to -105dBm. When the RSRP value uploaded by the data acquisition module 100 is greater than or equal to -105dBm, the signal indicator data is considered normal, and no color is marked on the map for that area (i.e., the map background color is retained). When the RSRP value uploaded by the data acquisition module 100 is less than -105dBm, the signal indicator data is considered substandard, and the network quality visualization module 300 marks the mobile terminal locations with substandard data on the map with a color that can be distinguished from the map background color, so that maintenance personnel can intuitively understand the signal quality of each area. At the same time, corresponding alarm work orders are generated so that maintenance personnel can analyze and optimize the network in that area.

[0023] It should be noted that because the network quality visualization module 300 displays a variety of signal indicator data on the map, different colors can be selected on the map to mark signal indicator data exceeding the corresponding threshold (i.e., abnormal) based on the signal indicator thresholds of different data points. Maintenance personnel can then select the corresponding color-marked points on the map to view the signal indicator data for that area. Furthermore, test points can be displayed based on different operators, network types, and time periods (e.g.,...). Figure 4 As shown). The network quality visualization module 300 can not only display the quality of each signal indicator data in the form of a map, but also in the form of charts (such as...). Figure 5 and Figure 6As shown), for example, based on the RSRP / SINR / RSRQ / RSSI indicators of the 4G network and the SS-RSRP / SS-SINR / SS-RSRQ indicators of the 5G network uploaded by the Mobile Cloud Testing APP through the data acquisition module 100, the average value statistics of the test data, the test terminal model statistics, the indicator analysis statistics, the network latency statistics, the uplink and downlink speed statistics, and the service area coverage TOP N statistics are generated. The network quality visualization module 300 of this embodiment supports custom date range queries, can query the network coverage distribution and network quality within a preset range, supports zooming the map to view specific network quality and details; supports selecting 4G network or 5G network to view network quality, supports viewing signal coverage, uplink and downlink speed, and signal comprehensive compliance rate; supports viewing uplink and downlink speed, network latency ratio and curves, including average speed curve, peak speed curve, average latency and minimum latency curve; supports viewing the number of information test points, and can separately count the total number of test points (number of mobile terminals tested), RSRP value, and SINR value; supports viewing the good points, bad points and tests of SINR and RSRP values ​​of different communication operators' coverage signals collected by the background configuration. Number of sampling points; supports customizable 4G / 5G, RSRP / SINR, and uplink / downlink rates via parameter configuration, and threshold settings for each level of PING latency (including five levels: "Very Good, Very Good, Average, Poor, and Extremely Poor"); supports comparing and viewing good and bad data indicators of SS-RSRP / RSRP and SS-SINR / SINR; supports filtering data statistics for a specific grid by inputting a grid location, such as inputting "xx street," which will only display data for that street; supports selecting data statistics for different scene attributes by scene attribute, such as selecting "residential" scene, which will only display data statistics for the residential scene, so that maintenance personnel can comprehensively understand the signal situation in the area based on the various signal quality indicators of mobile terminals.

[0024] In addition, the Network Quality Visualization Module 300 also includes a Terminal Adaptation Submodule, a Frequently Asked Questions (FAQ) Summary Submodule, a Personal Center Submodule, and a System Guide Submodule. The Terminal Adaptation Submodule provides information on terminal models compatible with China Broadcasting Network's mobile network, allowing maintenance personnel or users to select the appropriate terminal model and establish a connection with the Mobile Network Cloud Testing APP. The FQ Summary Submodule displays a summary of common terminal-related issues compatible with China Broadcasting Network's mobile communication network, enabling maintenance personnel or users to obtain timely solutions when encountering terminal connection problems. The Personal Center Submodule displays the current account's company, username, role type, login time, login IP, and copyright authorization information, and also supports password modification. The System Guide Submodule provides a table of commonly used terms and abbreviations for mobile communication network service indicators, allowing maintenance personnel to quickly refer to unfamiliar abbreviations.

[0025] In this embodiment, the data acquisition module 100 is also connected to a timing module. Maintenance personnel or users can control the time interval for the data acquisition module 100 to automatically collect signal data by setting the timing module. For example, the time interval for signal data collection includes, but is not limited to, 1, 5, 10, 20, 30, or 60 minutes, and can be adjusted according to requirements. Of course, maintenance personnel or users can also trigger the automatic collection of signal data (i.e., trigger a test task) by setting base station change conditions. In this embodiment, the network monitoring and alarm module 400 is used to issue an alarm and centrally analyze and manage abnormal data when the test service indicator results data appear in the data acquisition module 100 automatically collecting and reporting signal indicator data (performing automatic test services) under the control of the Mobile Network Cloud Test APP. When an active alarm occurs in the system, the network monitoring and alarm module 400 automatically generates a network test task work order. When multiple adjacent base stations have no signal within the same time period (e.g., 1 minute or 30 seconds) (the signal of the base station is collected and judged by the data analysis module 200), the network monitoring alarm module 400 initiates a regional network test task work order. The test task and work order management module 600 then dispatches test tasks to the data acquisition modules 100 in the corresponding area according to the area of ​​the regional network test task work order, so as to collect and upload data for analysis and respond to network anomalies in a timely manner.

[0026] In addition, the network monitoring and alarm module 400 generates an alarm monitoring list, provides system alarm item configuration, and system alarm item threshold configuration when issuing alarms. The alarm monitoring list provides system alarm query functionality; it supports querying historical alarms in reverse chronological order by time range; and displays alarm ID, alarm item name, alarm type, alarm location information, first alarm occurrence time, most recent alarm occurrence time, alarm frequency, alarm content, alarm recovery time, alarm confirmation time, and key information of the person who confirmed the alarm. It supports statistical analysis of alarm information and querying of historical alarm information by alarm level and alarm type; and supports manual confirmation, clearing, and temporary blocking of alarms. When the system actively generates an alarm, it automatically generates a network test task work order, providing various data query functions for system alarms; it supports statistical analysis of alarm information and querying of historical alarm information by alarm level and alarm type; and supports manual confirmation, clearing, and temporary blocking of alarms. The system alarm item configuration includes parameters such as RSRP, SINR, RSRQ, RSSI, uplink / downlink rates, and call completion rate for 4G LTE cells, and SS-RSRP, SS-SINR, SS-RSRQ, uplink / downlink rates, and call completion rate for 5G NR cells. It also includes alarm item name, service type, whether the alarm item is disabled, creation time, update time, and remarks. Adding, deleting, editing, and querying alarm items are supported. The system alarm item threshold configuration includes alarm item name, service type, alarm level, lower alarm threshold, upper alarm threshold, creation time, update time, and remarks. Adding, deleting, editing, and querying alarm item thresholds are also supported.

[0027] The user complaint handling module 500 is connected to the data acquisition module 100 to indirectly interface with the customer service system. This allows for the acquisition of user network-related complaint ticket information (i.e., complaint data) via an API interface. The complaint data includes the ticket number, user code, customer name, mobile phone number, fault type, fault issue, and fault address. The system supports querying user network-related complaint ticket records by ticket number, user code, customer name, and mobile phone number. In this embodiment, the user complaint handling module 500 supports the export of user network-related complaint ticket lists from the network testing coordination department for offline transfer to the superior network management department. It also supports the network testing coordination department selecting user network-related complaint records and initiating network testing task tickets, which are then dispatched to the test task and ticket management module 600 for testing by the network testing execution unit. In addition, in this embodiment, the user complaint handling module 500 is also used to initiate assistance processing procedures and query complaint handling status. It supports the presentation of process node information of network test task work orders, so that customer service can keep track of the processing progress of the network test task work orders corresponding to the user's network-related complaint work orders in real time. It supports clicking the work order number in the list of user network-related complaint work orders to jump to the corresponding network test task work order management interface and view the node information of the current network test task work order processing. It supports clicking the work order details button in the list of user network-related complaint work orders to view the details of the network test task work order corresponding to the user's network-related complaint work order. When calculating test results, it also supports switching between 4G / 5G and switching mobile communication operators, and highlights abnormal indicators in red.

[0028] The test task and work order management module 600 includes a special test task planning submodule, a special plan test task management submodule, and a work order management submodule. The special test task planning submodule is used to configure test areas or routes. It adds test task plans based on two task planning types: area-based fixed-point testing and drive testing. In area-based fixed-point testing, all mobile terminals within a specific area are tested. Drive testing includes fixed-path planning using fixed routes and sequential planning using dynamic routes. The special plan test task management submodule is used by the network testing coordination department to create test plans in the system and distribute them to network testing execution units. The network testing execution units then start and complete the test tasks themselves and upload the test results to the data analysis module 200 (system backend) for data analysis. In this embodiment, the test task and work order management module 600 supports querying and exporting the test results of planned test tasks and supports filtering a list of cells with problematic test results. This list is used by the network testing coordination department to forward the results to the higher-level network management department through offline channels. After receiving feedback from the higher-level network management department, the network testing coordination department initiates a retest task. Only after the retest is successful can the planned test task be closed in a closed loop.

[0029] The following example illustrates the process of adding test plan tasks in the Test Task and Work Order Management Module 600.

[0030] Please combine Figure 7 In the interface of the Test Task and Work Order Management Module 600, test scenarios include daily testing, regular large-scale testing, major events, important holidays, and emergencies; test types include road testing (DT) and regional fixed-point testing (CQT); test task planning includes selecting the initial task planning list configuration to directly obtain the test location or test path; test dates include selecting the start date and end date of the test; test time periods include three time periods: 8:00-12:00, 12:00-16:00, and 16:00-20:00, and multiple time periods can be selected.

[0031] After a test plan task is added, the network testing coordination department creates the planned test task in the system and dispatches it to the network testing execution unit. The network testing execution unit receives the planned test task, starts the task in the system, and begins testing. After completing the planned test task, the network testing execution unit confirms completion in the system. During the test, users can click on the planned test task name to view the current test task trajectory, including the test route and test location, and simultaneously view the approximate location of the base station, signal coverage, and test indicator results statistics (the most recent test data is displayed by default). It should be noted that in this embodiment, the initiation and implementation of the planned test task are performed when it is necessary to retest areas with abnormal signal data, in order to process these abnormal areas and ensure the signal quality of the entire mobile network system.

[0032] In this embodiment, the work order types of the operation and maintenance management system include network problem feedback work orders initiated for problematic road sections or community addresses in the network test results of special plan test tasks; complaint-type network test task work orders manually initiated after review by the network test coordination department; and monitoring alarm work orders automatically initiated in the event of monitoring alarms. The management process of network problem feedback work orders by the work order management submodule includes: after the completion of the special plan test task, if there are problems with the network test results, the test task and work order management module 600 automatically initiate a network problem feedback work order and dispatch it to the network test coordination department, which accepts and processes the order, and returns the order upon completion. This type of work order data is exported and used by the network test coordination department to transfer it to the superior network management department through offline channels. The management process of complaint-type network test task work orders by the work order management submodule includes: the network test coordination department dispatches the work order to the network test execution unit according to this work order type, the network test execution unit accepts and processes the order, and returns the order upon completion. The work order management submodule manages monitoring alarm work orders as follows: The test task and work order management module 600 automatically generates monitoring alarm work orders based on the type of work order and the administrative region to which the community belongs, and dispatches them to the network test execution unit in the corresponding region. The network test execution unit accepts the order, processes it, and returns the order upon completion.

[0033] The work order management submodule includes work order creation, work order dispatch, work order acceptance, work order return, transfer to the superior network management department, and retest task creation. Among them, retest task creation includes inputting the test date, test period, and remarks.

[0042] The operation and maintenance management system also includes a mobile application module 900. Based on a third-party communication platform, this module provides an interactive interface for operation and maintenance personnel to interact with the system during daily operations. The mobile application module 900 uses WeChat Work as its entry point, developing a mobile application based on the WeChat Work open platform. It provides a system homepage, task management, and work order management functions. The system homepage presents a summary analysis and statistics of 4G and 5G signals across the entire network, analyzing compliance rates, coverage rates, speed and latency trends, and the number of test points. Data can be queried by today, yesterday, the last 7 days, the last 30 days, and custom time periods. Speed ​​trend analysis supports viewing by 4G and 5G, and allows viewing uplink / downlink rates, average rates, peak rates, high-speed percentages, network latency, etc. Task management allows viewing pending, processing, and completed test tasks on the mobile device, supporting operations such as dispatching, receiving, and completing tasks, and viewing the route or location map for the test task. The work order management system supports work order acceptance and return operations on mobile devices. The network testing coordination department (system administrator) can view all work orders, and can view and process work orders assigned to the network integration team. The network testing execution unit can view and process assigned network testing task work orders (including retest work orders). The work order details in the work order management function of mobile application module 900 display the work order number, fault information, work order source, and current status. Work orders assigned to the network integration team are marked "Province," those for retesting are marked "Retest," and those without any information are not displayed. The operation buttons distinguish between administrators, network integration teams, and network testing teams.

[0043] Please combine Figures 1-3The Mobile Network Cloud Testing APP is associated with the mobile application module 900 and is loaded onto mobile terminals for network signal testing. It should be noted that this APP can be loaded onto users' mobile phones, allowing them to report network signal problems through the 10999 system after testing their own phones. In this case, the user complaint processing module 500 receives complaint data and generates complaint work orders for full tracking and processing of user complaints. Alternatively, the APP can be loaded onto the mobile phones of maintenance personnel, enabling them to perform automatic network testing upon arrival at the designated testing area. In other words, the data acquisition module 100 can be deployed on either users' or maintenance personnel's mobile terminals. While collecting complaint and signal data from the mobile terminal and uploading it to the data analysis module 200, the APP on the mobile terminal also performs basic analysis of the test data. In this embodiment, the Mobile Network Cloud Test APP is used to replace the data collection module 100. It can perform mobile network analysis (including automatic background resident of the APP and automated testing), seamless testing, call detection, application response detection, uplink and downlink rate analysis, mobile network analysis results, quality map, data reporting settings, and upload test data to a designated server.

[0044] Specifically, when performing mobile network analysis, maintenance personnel can create work orders through the test task and work order management module 600, and the data acquisition module 100 collects signal data, while the data analysis module 200 analyzes the signal data to realize the detection of indicators such as RSRP, RSRQ, RSSI, SINR of 4G network and SS-RSRP, SS-RSRQ, SS-SINR of 5G network of 4G network of Serving cell and neighboring cell, as well as the latitude and longitude of operator and test location. During seamless testing, the MobileNetCloudTest APP is installed on the mobile phones of maintenance personnel. This APP runs automatically in the background, allowing personnel to periodically and automatically test their mobile network while on the move. For routine seamless automated testing of shared mobile base stations, the system backend generates network signal test snapshots for each base station. Combined with data from the shared mobile base station coordination department, the system matches data from base stations that haven't undergone network testing weekly and automatically performs check-in tests via the MobileNetCloudTest APP to comprehensively test the network in each area. Furthermore, the MobileNetCloudTest APP supports enabling / disabling automatic detection, setting background checks at fixed intervals (selectable from a dropdown menu), setting checks when the current location is outside signal coverage, and setting combinations of time intervals and location changes. It also supports selecting test cards, such as selecting SIM 1 and SIM 2, for automatic mobile network signal detection. After automatic detection, the MobileNetCloudTest APP automatically uploads the results to the mobile application module 900 for backend personnel to view.

[0045] During call testing, maintenance personnel in the test area can configure their devices to automatically dial customer service numbers for China Broadcasting Network and China Mobile. They can set timeout periods, voice call durations, input grid information, select scenarios, and automatically identify test addresses to perform call quality testing. During application response testing, it allows for pinging, DNS resolution, and latency analysis of commonly used applications on the local machine. During uplink and downlink rate analysis, it enables testing of 5G and 4G network uplink and downlink rates, obtaining test results and uplink / downlink rate data curves for network latency, download speed, and upload speed.

[0046] Mobile network analysis results are used to present basic information, including serving cell data network, cell type, tracking area code, physical cell identifier, cell identity identifier, radio channel code, frequency, bandwidth, location area identification, and service status code. It also includes statistics on neighboring cell indicators, signal received power, signal received quality, and signal-to-noise ratio. Furthermore, the mobile network analysis results can generate and display a quality map, showing the current location's signal strength and weaknesses compared to historical test signal strengths. This allows maintenance personnel to understand signal quality changes in the area and evaluate maintenance operations. Test data is reported by configuring the server IP and port for receiving data in the Mobile Network Cloud Test APP. It supports setting data upload methods, including automatic upload, manual upload, and fixed-time upload, and also supports setting automatic detection. During data reporting, test record data and data management can be viewed. Data management allows manual upload of test data to the server by selecting test data; the default is automatic upload to the server.
