[0090] Embodiment 1:

[0091] This embodiment provides a diagnostic method for 5G voice service complaints in a mobile network. This method can be applied to the customer service center and the technical support department. Through an intelligent expert library model, it can automatically analyze and judge various complaint problems encountered by users during the use of 5G voice services. This method can quickly obtain the complaint problems of users and relevant registration information, so as to efficiently provide accurate diagnostic results and solution suggestions. It is applicable to various scenarios such as user troubleshooting, voice quality problems, service interruptions, etc., and can significantly improve the customer service response speed and overall service quality, enhancing the user experience.

[0092] As Figure 1 shown, the diagnostic method for 5G voice service complaints in this embodiment specifically includes the following steps:

[0093] Step K1: Obtain the complaint problem of the 5G voice service complaint in the mobile network and the telephone number corresponding to the complaining user.

[0094] As a specific implementation manner, the obtaining of the complaint problem of the 5G voice service complaint in the mobile network and the telephone number corresponding to the complaining user specifically includes the following steps:

[0095] Automatically obtain the complaint work order of the 5G voice service from the customer service system or the online service platform;

[0096] Respectively extract the complaint problem and the telephone number corresponding to the complaining user from the complaint work order, so as to obtain the complaint problem of the 5G voice service complaint in the mobile network and the telephone number corresponding to the complaining user.

[0097] The specific steps of obtaining the complaint problem of the 5G voice service complaint in the mobile network and the telephone number corresponding to the complaining user can be divided into several stages. First, the system seamlessly docks with the customer service system or the online service platform through an interface, and automatically retrieves the complaint work orders related to the 5G voice service. This process not only improves work efficiency but also reduces the error of manual operation. Subsequently, the system deeply analyzes each complaint work order to extract the key information therein, including the specific complaint problems reflected by the user, such as poor call quality, unstable connection, or insufficient signal coverage. At the same time, the telephone number submitted by the user will also be extracted. This series of automated processing steps ensures that the complaint information and user contact information related to the 5G voice service in the mobile network can be accurately and comprehensively obtained, laying a solid foundation for subsequent scientific diagnosis and effective handling, and ultimately improving the user satisfaction and service quality.

[0098] Step K2: According to the complaint problem and the telephone number, query the subscription and registration information of the complaining user in the core network to obtain the user subscription registration information.

[0099] Query the subscription and registration information of the complaining user in the core network according to the complaint problem and the telephone number, and the specific steps are as follows:

[0100] Define a query target according to the complaint problem;

[0101] Among them, the query target is the voice calling status, and / or the voice called status, and / or the roaming permission, and / or the call forwarding status, and / or the shutdown or startup status, and / or the registration status;

[0102] According to the query target, query the subscription and registration information of the complaining user in the core network from the network elements, and perform color brightness marking on the abnormal subscription and registration information;

[0103] Among them, the network elements are the User Data Management Center (UDM), and / or the VoLTE Application Server (VoLTE AS), and / or the Session Control Function (S-CSCF), and / or the ENUM Domain Name System (ENUMDNS), and / or the virtual circuit switching (vCS); when there are multiple network elements, synchronously obtain the subscription and registration information of the complaining user in the core network from multiple network elements for query.

[0104] The obtaining of the subscription and registration information of the complaining user in the core network from the network elements specifically includes:

[0105] Obtain the voice calling status from the VoLTE Application Server (VoLTE AS), Session Control Function (S-CSCF), ENUM Domain Name System (ENUMDNS), and virtual circuit switching (vCS) services; and,

[0106] Obtain the voice called status from the VoLTE Application Server (VoLTE AS), Session Control Function (S-CSCF), ENUM Domain Name System (ENUMDNS), and virtual circuit switching (vCS) services; and,

[0107] Obtain the roaming permission from the User Data Management Center (UDM) service; and,

[0108] Obtain the call forwarding status from the User Data Management Center (UDM) and Session Control Function (S-CSCF) services; and,

[0109] Obtain the shutdown or startup status from the User Data Management Center (UDM) service; and,

[0110] Obtain the registration status from the User Data Management Center (UDM) and Session Control Function (S-CSCF) services;

[0111] The VoLTE Application Server (VoLTE AS) service is obtained by connecting to the VoLTE AS through the SSH protocol;

[0112] The Session Control Function S-CSCF service is obtained by connecting to the S-CSCF using the Telnet protocol;

[0113] The User Data Management Center UDM service is obtained by constructing a SOAP request and using the SOAP protocol;

[0114] The ENUM Domain Name System ENUMDNS service is obtained by querying the telephone number registration status of the user through an HTTP GET request;

[0115] The Virtual Circuit Switching vCS service is obtained by querying through an API or a command-line tool.

[0116] Step K3: Input the complaint problem and the user subscription and registration information into the expert library model to obtain a diagnosis result and a diagnosis suggestion, so as to complete the diagnosis of the 5G voice service complaint in the mobile network; the expert library model is an intelligent diagnosis tool pre-constructed based on the logical rules set by expert experience, combined with the impact of the complaint scenario, network element priority, and subscription function on the 5G voice service in the mobile network.

[0117] Before specifically implementing this step, an expert library model needs to be constructed first;

[0118] The construction of the expert library model specifically includes the following steps:

[0119] Based on the experience and knowledge of experts in handling 5G voice service complaints in the mobile network, preset the complaint scenario;

[0120] Based on the preset complaint scenario and according to the instruction parameter specifications and parameter values in the standard knowledge base, set the diagnostic logic rules; and, according to the 5G service function, set the network element priority of the 5G voice service complaint in the mobile network.

[0121] Among them, the diagnostic logic rules include complaint type classification, diagnostic priorities for different complaint types, and the impact of user subscription and registration information on the quality of the 5G voice service;

[0122] Based on the diagnostic logic rules and the network element priority, clarify the specific reasons for different complaint problems;

[0123] Based on the experience and knowledge of experts in handling 5G voice service complaints in the mobile network, determine the specific solutions corresponding to the specific reasons;

[0124] Summarize the complaint problems, the diagnostic logic rules, the network element priority, the specific reasons, and the specific solutions to obtain the expert library model.

[0125] As a more specific implementation, before setting the diagnostic logic rules based on the preset complaint scenarios and in accordance with the instruction parameters and parameter values in the standard knowledge base, the method further includes: constructing a standard knowledge base;

[0126] The construction of the standard knowledge base specifically includes the following steps:

[0127] Collect relevant query instructions and parameter specifications from the network elements of the core network;

[0128] Determine the influencing parameters affecting the 5G voice service from the query instructions and the parameter specifications;

[0129] Set a normal value range or status for each of the influencing parameters to obtain the influencing parameter specifications;

[0130] Organize the query instructions, the parameter specifications, and the influencing parameter specifications to form a knowledge base for extracting user data affecting the 5G voice service from the network elements, thereby obtaining the standard knowledge base.

[0131] As a specific implementation, setting the network element priority for complaints about the 5G voice service of the mobile network specifically includes the following steps:

[0132] Identify the 5G service functions; the 5G service functions include basic voice functions, roaming permissions, call forwarding, and outage status;

[0133] Determine the network elements affecting the 5G service functions;

[0134] Set the network element priority for complaints about the 5G voice service of the mobile network;

[0135] Among them, setting the network element priority for complaints about the 5G voice service of the mobile network specifically includes: setting the network elements affecting the basic voice function as the first priority; and setting the network elements affecting the roaming permissions as the second priority; and setting the network elements affecting the call forwarding as the third priority; and setting the network elements affecting the outage status as the fourth priority.

[0136] In this embodiment, through the expert library model, the automatic diagnosis of complaints about the 5G voice service in the mobile network is realized, which completely does not require manual intervention, and the user only needs to click a button to complete the diagnosis. As Figure 2 shown, the specific steps of this method include five steps: data collection, service logic judgment, data query, data analysis, and result presentation.

[0137] The first step is data collection: For key network elements in the core network, including User Data Management (UDM), VoLTE Application Server (VoLTE AS), Call Session Control Function (CSCF), ENUM Domain Name System (ENUM DNS), and virtual Circuit Switching (vCS), specific instructions for querying 5G voice user subscription functions and registration information will be collected. Subsequently, the execution results of normal service-state users will be analyzed, with a focus on extracting the key parameter specifications that affect voice functions. These key parameters include, but are not limited to, the access network type, the activation status of basic voice services (such as basic calls, emergency calls, etc.), the settings of roaming permissions (domestic roaming, international roaming, etc.), the real-time information of the power-on / off status, the configuration of the call forwarding function, the identification of the registered network element, and the confirmation of the registration status, etc.

[0138] For each key parameter, its normal parameter value range or status will be clarified. For example, the access network type should support multiple networks such as 5G, 4G, 3G, and 2G, the basic voice services need to be in an activated state, the roaming permissions are configured according to user needs, the power-on / off status should be powered on, the call forwarding function should be configured according to user settings, the registered network element should be the network element where the user is currently located, and the registration status should be registered, etc.

[0139] Finally, all query instructions, key parameter specifications, and their normal parameter values will be sorted and summarized into a standard knowledge base. This knowledge base will serve as an important basis for subsequent service logic judgment, helping to quickly and accurately locate and solve problems encountered by 5G voice users during use.

[0140] The second step is service logic judgment: Specifically, as Figure 3 shown, first, based on the experience of experts, manual logical analysis is carried out, complaint scenarios are preset, the involved network elements, the content to be queried, and specific query instructions are clarified. At the same time, priority sorting is set, the key fields and their correct parameter values are determined. In this process, each key point is deduced one by one to confirm each query conclusion, and based on this, the diagnostic results and corresponding suggestions for each key point are provided. On the basis of this process, an expert library for 5G voice service complaint logic judgment analysis is constructed.

[0141] Next, using digital and intelligent means, according to various complaint scenarios recorded in the logic judgment analysis expert library, parallel logical judgments are carried out in the order of network element priorities and the priorities of the impact of subscription functions on user voice services. Specifically, as Figure 4As shown, if it is found during the preliminary logical analysis stage that a basic voice function with a higher priority (such as the TS11 function) is not enabled in the User Data Management (UDM), the system will immediately abort the subsequent detailed analysis, directly present the summary of the query results based on the constructed expert library for logical judgment analysis, intuitively give the diagnostic result, and provide targeted optimization and solution suggestions.

[0142] In addition, the one - key diagnosis device for 5G voice service complaints uses deep learning technology to deeply understand each subscribed function of the user on the core network - related network elements, checkpoints of the registration status, query instructions, main parameters, and judgment logic, so as to accurately locate the root cause of the problem.

[0143] As Figure 5 shown, in the diagnostic logic of 5G voice service roaming permissions, it is first necessary to understand two main areas it covers: Circuit Switched (CS) and IP Multimedia Subsystem (IMS). The roaming permissions of the CS voice function can be divided into three cases: domestic, international, and unknown, involving network elements such as the Home Subscriber Server (HSS) and Unified Data Management (UDM); while the IMS voice roaming permissions also include domestic, international, and unknown. The data related to EPC can be obtained from the UDM, mainly involving network elements such as the VoLTE Application Server (VoLTE AS). The diagnostic function of the voice service roaming permissions is divided into four sub - items, which respectively perform accuracy diagnosis on international roaming permissions, 2 / 3G service roaming permissions, 4G service roaming permissions, and 5G service roaming permissions. Finally, after summarizing the four results, a comprehensive analysis is carried out to obtain the final diagnostic result. Taking the user's international roaming permissions as an example, the diagnosis will check whether the user has enabled international roaming permissions, query through the SOAP interface instruction "LST_ODBDAT" of a certain company, and the return example of the main parameters is presented in XML format, including the user's IMSI, ISDN, and relevant roaming permission status information. For example, when "ResultCode" is 0, it indicates success.

[0144] The specific instructions are as follows:

[0145]

[0146]

[0147] In the code, "NOBAR" means allowing the user to roam internationally, while "BAR" means not allowing the user to roam internationally.

[0148] In the third - step data query, the basic information of the user will be mainly checked, such as whether the functions of voice calling, voice called, roaming permission, call forwarding, power - on / off status, and registration status are normal. This process involves multiple network elements such as UDM, VoLTE AS, S - CSCF, ENUMDNS, and vCS. According to the communication protocols used by each network element (including SOAP - based WebService, SSH, Telnet, and vendor - defined protocols), synchronous data query will be performed and user data will be extracted. Specifically, first, a request is constructed through the SOAP protocol and the remote WebService is called to obtain the user service subscription and registration information of the UDM network element in XML format; then, SSH or Telnet is used to execute commands to obtain the user subscription and registration data of the S - CSCF, VoLTE AS, and vCS network elements. Finally, according to the phone number and problems of the complaining user, a query is made, key parameters are filtered out, and the valid data is organized into a normalized format and stored in the database for subsequent data analysis.

[0149] In the fourth - step data analysis, the user data queried will be comprehensively and deeply analyzed according to the judgment conditions of the 5G voice service complaint - handling logic (which has been organized into an expert library in the second step), and the results will be summarized to output the diagnostic results and suggestions. This analysis process mainly uses SAX (Simple API for XML) parsing technology. Through a custom ContentHandler, accurate identification and information extraction, data conversion, and validity verification of key elements in the XML - formatted data are realized, thus providing solid data support for the output of the diagnostic results. In the ContentHandler, the parsing logic for the complaint scenarios and judgment conditions will be written, specifically including identifying specific tags (such as UserBasicInfo, CommunicationStatus, SubscriptionInfo, and RegistrationStatus) to locate the key data parts, extracting key fields (such as subscription functions, roaming permissions, power - on / off status, and registration status) and accurately extracting them according to the XML structure, and at the same time performing data conversion and verification, converting the extracted data into the format used inside the program and ensuring that it conforms to the business logic and expected values.

[0150] In the result presentation of the fifth step, the front-end data display of the 5G voice one-key diagnosis device uses the React framework combined with the Ant Design (AntD) framework. Through the component-based development mode of React, an efficient and reusable user interface is constructed, and the high-quality UI component library provided by AntD is used to achieve beautiful and professional data display effects. The device clearly and orderly displays key information such as the user number, detailed complaint information, instant query results, accurate diagnosis conclusions, targeted diagnosis suggestions, convenient expand details buttons, and detailed results of various network element queries. For any detected abnormal problems, red highlighting is used to effectively help operation and maintenance personnel quickly identify the core problems of user complaints in a prominent way, thus significantly improving the efficiency and quality of problem handling.

[0151] This embodiment deeply integrates various network element communication protocols of the 5G network and the IMS network, realizing real-time seamless interaction with key network elements of the 5G core network and the IMS network. Through automation and intelligent technologies, it can efficiently capture the subscription and registration data of users, greatly reducing manual operations, thus significantly improving the operation efficiency. At the same time, with the help of deep learning technology, the device can pre-insight the normal subscription and registration status of users in relevant network elements of the mobile core network. Based on key conditions such as the user's telephone number and complaint matters, in-depth and comprehensive analysis of user data is carried out to intelligently identify problems with the subscription function and registration status that affect 5G voice services, including abnormal function subscriptions, arrears outages, abnormal registered network status, and call forwarding activation status. Finally, based on the priority judgment of the impact on user service usage, the device can output accurate diagnosis results and improvement suggestions, greatly improving the efficiency and accuracy of diagnosing user complaint problems.
