Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, communication device and communication system. Background Technology

[0002] In the process of network commercialization, to improve user experience, operators have launched differentiated service packages. For example, through guaranteed bit rate (GBR), dedicated network acceleration can be provided for high-value users. Furthermore, service operation equipment can send SMS messages to users at the end or beginning of each month on a monthly basis to inform them of the effectiveness of the service guarantee.

[0003] The above methods suffer from problems such as information lag and poor interactivity, making it difficult to meet users' needs for real-time perception of the effectiveness of business assurance. Summary of the Invention

[0004] This application provides a communication method, communication device, and communication system to meet users' real-time perception needs for service assurance effectiveness.

[0005] In a first aspect, embodiments of this application provide a communication method. This method can be applied to a policy control device (also called a communication device), which can be a policy control network element, a module (e.g., a circuit, chip, or chip system) within the policy control network element, or a logical node, logical module, or software capable of implementing all or part of the functions of the policy control network element. For example, the policy control network element can be a policy control function (PCF) network element or other network element with policy control functions. The method includes: receiving a first request message from a service operation device, the first request message including a user identifier, the first request message being used to request a service assurance report from the user, the service assurance report being used to indicate the effectiveness of quality assurance for the user's service, the service operation device serving a terminal device corresponding to the user; sending a second request message to an analysis data storage device, the second request message including a user identifier, the second request message being used to request the service assurance report; receiving the service assurance report from the analysis data storage device, the service assurance report being determined based on the user's service assurance document; and sending the service assurance report to the service operation device.

[0006] Based on the above solution, it is possible to generate a user's protection report in real time based on the user's business protection documents and send it to the terminal device for the user to view. It has good interactivity and real-time performance and can meet the user's need for real-time perception of the effectiveness of business protection.

[0007] As one possible implementation method, the service assurance report is sent from the service operation device to the terminal device.

[0008] Based on the above solution, it is possible to provide users with real-time feedback on business assurance reports based on user requests, which can meet users' needs for real-time perception of the effectiveness of business assurance.

[0009] As one possible implementation, before receiving the first request message from the business operation device, the method further includes: sending instruction information to the analysis data storage device, the instruction information being used to instruct the received business assurance document to be saved.

[0010] Based on the above scheme, by sending instruction information to the analysis data storage device to indicate that the received business assurance documents should be saved, the analysis data storage device can accurately determine that the business assurance documents need to be saved, so as to correctly generate the business assurance report.

[0011] As one possible implementation, sending the instruction information to the analysis data storage device includes: sending a first message to the network data analysis device, the first message being a subscription request message or a subscription update message, the first message including the user's identifier, a subscription event, and the instruction information, the subscription event indicating that the user's quality of service should be analyzed; wherein the instruction information is sent from the network data analysis device to the analysis data storage device.

[0012] Based on the above scheme, the control strategy device first sends the aforementioned instruction information to the network data analysis device, and then the network data analysis device sends the aforementioned instruction information to the analysis data storage device. On the one hand, the network data analysis device can, based on the instruction information, know that the analysis data storage device needs to save the service guarantee document received from the user, thereby triggering the network data analysis device to report the user's service guarantee document to the analysis data storage device, which helps the analysis data storage device to correctly obtain the user's service guarantee document. On the other hand, the strategy control device sends the instruction information to the network data analysis device by carrying it in the subscription request message or subscription update message, which can reuse the subscription request message or subscription update message of the existing technology without using a new message to carry the instruction information, thus reducing signaling overhead.

[0013] As one possible implementation, the method further includes: determining that a control plane session of the user has been established and the user's service assurance subscription process has been completed; determining the address information of the analysis data storage device based on the user's identifier; and sending the instruction information to the analysis data storage device includes: sending the instruction information to the analysis data storage device based on the address information of the analysis data storage device.

[0014] Based on the above scheme, the strategy control device can directly send the above instruction information to the analysis and data storage device, which is relatively efficient.

[0015] Secondly, embodiments of this application provide a communication method that can be applied to an analytics data storage device (also called a communication device). This analytics data storage device can be an analytics data storage network element, a module (e.g., a circuit, chip, or chip system) within the analytics data storage network element, or a logical node, logical module, or software capable of implementing all or part of the functions of the analytics data storage network element. For example, the analytics data storage network element can be an analytics data repository function (ADRF) network element or other network elements with analytics data storage functions. The method includes: receiving a second request message from a policy control device, the second request message including a user identifier, the second request message being used to request a service assurance report from the user, the service assurance report being used to indicate the effectiveness of quality assurance for the user's services; sending the service assurance report to the policy control device, the service assurance report being determined based on stored service assurance documents of the user, the service assurance report being sent by the policy control device to the user's corresponding terminal device via a service operation device.

[0016] Based on the above solution, it is possible to generate a user's protection report in real time based on the user's business protection documents and send it to the terminal device for the user to view. It has good interactivity and real-time performance and can meet the user's need for real-time perception of the effectiveness of business protection.

[0017] As one possible implementation, the method further includes: receiving the service assurance document from the network data analysis device; and determining the service assurance report based on the service assurance document.

[0018] Based on the above scheme, the data storage device can obtain the user's business assurance documents, which facilitates the generation of the user's business assurance report based on the user's business assurance documents, and enables accurate determination of the business assurance report.

[0019] As one possible implementation, the method further includes: receiving instruction information from the policy control device, the instruction information being used to instruct the received business assurance document to be saved.

[0020] Based on the above scheme, by receiving instruction information from the strategy control device to indicate that the received business assurance documents should be saved, the analysis data storage device can accurately determine that the business assurance documents need to be saved, so as to correctly generate the business assurance report.

This network data analysis device can be a network data analysis network element, a module within the network data analysis network element (e.g., a circuit, chip, or chip system), or a logical node, logical module, or software capable of implementing all or part of the functions of the network data analysis network element. For example, the network data analysis network element can be a network data analysis function (NWDAF) network element or other network elements with network data analysis functions. The method includes: receiving a first reporting message from a user plane network element, the first reporting message including a user identifier and key performance indicator (KPI) information prior to assurance for at least one application of the user; triggering a service assurance process for the user based on the KPI information prior to assurance for at least one application of the user, and generating a service assurance document for the user; sending a second reporting message to an analysis data storage device, the second reporting message including the user identifier and the service assurance document, the service assurance document being used to generate a service assurance report for the user, the service assurance report being used to indicate the effectiveness of quality assurance for the user's services.

[0024] Based on the above scheme, the network data analysis device receives instruction information from the control policy device, and then sends the instruction information to the analysis data storage device. On the one hand, the network data analysis device can, based on the instruction information, know that the analysis data storage device needs to save the service guarantee document received from the user, thereby triggering the network data analysis device to report the user's service guarantee document to the analysis data storage device, which helps the analysis data storage device to correctly obtain the user's service guarantee document. On the other hand, the policy control device sends the instruction information to the network data analysis device by carrying it in a subscription request message or subscription update message. This allows for the reuse of existing subscription request messages or subscription update messages without needing to use new messages to carry the instruction information, thus reducing signaling overhead.

[0028] As one possible implementation, the third request message also includes a statistical time range, which is used to request the user's service assurance report corresponding to the statistical time range.

[0070] To meet users' needs for real-time perception of business assurance effectiveness, this application provides corresponding solutions.

[0071] The communication method, communication device, and communication system provided in this application will be described below with reference to the accompanying drawings. It will be understood that in the embodiments of this application, the entities performing the interaction include a policy control device, an analysis and data storage device, a network data analysis device, a service operation device, and a terminal device. For details regarding the functions and specific implementation methods of these devices, please refer to the preceding description.

[0072] Figure 3 This is a flowchart illustrating a communication method provided in an embodiment of this application. The method includes the following steps.

[0073] Step 301: The terminal device sends a third request message to the service operation device. Correspondingly, the service operation device receives the third request message.

[0074] The third request message includes the user's identifier (such as a subscription permanent identifier (SUPI) or a generic public subscription identifier (GPSI)) and is used to request a service assurance report from the user, which indicates the effectiveness of quality assurance for the user's services.

[0075] Optionally, the third request message also includes a statistical time range, which is used to request a service assurance report from the user corresponding to that statistical time range. Based on this method, it is possible to flexibly indicate the statistical time range corresponding to the requested service assurance report.

[0076] Step 302: The service operation device sends a first request message to the policy control device. Correspondingly, the policy control device receives the first request message.

[0077] The first request message includes the user's identifier and is used to request the user's business assurance report.

[0078] If the third request message includes a statistical time range, the first request message also includes that statistical time range.

[0079] As one implementation method, prior to step 301 above, the policy control device also sends a subscription request message to the service operation device. This subscription request message includes the user's identifier and a subscription event, where the subscription event is a query for a service assurance report by the terminal device. Accordingly, step 302 specifically involves the service operation device sending a first request message to the policy control device based on the subscription request message. That is, based on the subscription request message from the policy control device, the service operation device determines whether the terminal device requests access to the user's service assurance report, and then requests the service assurance report from the policy control device. Based on this method, the service operation device can accurately and quickly obtain the user's service assurance report from the policy control device.

[0080] Step 303: The strategy control device sends a second request message to the analysis data storage device. Correspondingly, the analysis data storage device receives the second request message.

[0081] The second request message includes the user's identifier and is used to request a business assurance report.

[0082] If the first request message includes a statistical time range, the second request message also includes that statistical time range.

[0083] Step 304: The analysis data storage device sends a service assurance report to the policy control device. Correspondingly, the policy control device receives the service assurance report.

[0084] The user's service assurance report is determined by the analytical data storage device based on the user's service assurance documents. That is, the analytical data storage device holds the user's service assurance documents, and upon receiving the aforementioned second request message, it determines the user's service assurance report based on the stored user's service assurance documents.

[0085] If the second request message also includes a statistical time range, then the service assurance report sent in step 304 is a service assurance report corresponding to that statistical time range.

[0086] For example, in this embodiment of the application, the user's business assurance document includes the user's identifier and business assurance record information corresponding to at least one of the user's applications; wherein, the business assurance record information for each application includes the application's identifier and at least one of the following: the application's assurance start time, the application's assurance end time, the application's KPI information before assurance, or the application's KPI information after assurance. Based on this method, diverse content of assurance documents can be provided, facilitating the flexible generation of business assurance reports.

[0087] The application's pre-guarantee KPI information includes at least one of latency, packet loss rate, bandwidth, stuttering rate, or speed. The application's post-guarantee KPI information includes at least one of latency improvement ratio, improved latency, bandwidth improvement ratio, improved bandwidth, stuttering rate improvement ratio, improved stuttering rate, speed improvement ratio, or improved speed. The service quality parameters for the application's corresponding guaranteed bearer include at least one of 5G QoS identifier (5QI), GBR, or allocation and retention priority (ARP).

[0088] As one implementation method, in this embodiment, the user's business assurance report includes the identifier of at least one of the user's applications, and at least one of the following: the number of assurance attempts, the duration of assurance, or the post-assistance KPI information for each application. This method uses application granularity to statistically analyze at least one of the following: the number of assurance attempts, the duration of assurance, or the post-assistance KPI information for each of the user's applications. Based on this method, the generated business assurance report can fully reflect the assurance effectiveness, improve user experience, and meet the user's personalized needs.

[0089] As another implementation method, in this embodiment, the user's business assurance report may further include at least one of the following: the number of times the user received assurance, the duration of assurance, or the KPI information after assurance. That is, this method does not distinguish between the number of times the user received assurance, the duration of assurance, or the KPI information after assurance for each application, but rather counts at least one of these information at the user level. Based on this method, the generated business assurance report can fully reflect the assurance effect, improve user experience, and meet users' personalized needs.

[0090] As one implementation method, the service assurance document for the user stored in the analysis data storage device can originate from the network data analysis device. For example, a user plane network element (e.g., a UPF network element) can collect pre-assertion KPI information (e.g., at least one of latency, packet loss rate, bandwidth, lag rate, or speed) for at least one of the user's applications. The user plane network element sends a first reporting message to the network data analysis device, which includes the user's identifier and the pre-assertion KPI information for at least one of the user's applications. Based on the pre-assertion KPI information for at least one of the user's applications, the network data analysis device determines whether to initiate the user's service assurance process, thereby triggering the user's service assurance process and generating the user's service assurance document within the process. Then, the network data analysis device sends a second reporting message to the analysis data storage device, which includes the user's identifier and the user's service assurance document. Based on this method, the analysis data storage device can obtain the user's service assurance document, facilitating the subsequent generation of the user's service assurance report based on the document.

[0091] For example, before sending the first reporting message to the network data analysis device, the user plane network element also determines whether the reporting conditions (e.g., latency greater than a latency threshold, bandwidth less than a bandwidth threshold, etc.) are met based on the pre-guarantee KPI information of at least one application of the user. If the reporting conditions are met, the user plane network element sends the aforementioned first reporting message to the network data analysis device. Based on this method, sending the pre-guarantee KPI information of at least one application of the user to the network data analysis device only when specific conditions are met, rather than sending the pre-guarantee KPI information of at least one application of the user under all conditions, can reduce signaling overhead.

[0092] For example, after determining that the user's service assurance process needs to be initiated based on the pre-assistance KPI information of at least one of the user's applications, the network data analysis device further determines whether the user's service assurance process is allowed to be initiated based on the radio resources of the cell the user is accessing. That is, if there are sufficient radio resources to support the initiation of the user's service assurance process, then the user's service assurance process is triggered. Based on this method, it can be guaranteed that the user's service assurance process can be correctly initiated.

[0093] Step 305: The policy control device sends a service assurance report to the service operation device. Correspondingly, the service operation device receives the service assurance report.

[0094] Step 306: The service operation device sends a service assurance report to the terminal device. Correspondingly, the terminal device receives the service assurance report.

[0095] Optionally, step 307 may also be included, whereby the terminal device displays a service assurance report.

[0096] Figure 4(a) shows an example of querying a service assurance report on a terminal. By clicking the "Service Assurance Report" button or icon displayed on the terminal interface, the user can trigger the terminal device to send the aforementioned third query request to the service operation device. Subsequently, the terminal device can receive the service assurance report from the service operation device and display the service assurance report on the terminal interface.

[0097] Figure 4(b) shows an example of a service assurance report displayed on a terminal. Users can intuitively view the content of the service assurance report, enhancing the user experience. In this example, the service assurance report shows that for this user, there were 109 assurance events in January 2026, with a assurance duration of 6 hours and 30 minutes and a latency improvement rate of 10%. Furthermore, by clicking on the various icons, users can also view the number of assurance events, assurance duration, and latency improvement rate for each application for that user.

[0098] Based on the above scheme, users can request and query their business assurance reports in real time. The network side can generate the user's assurance report in real time based on the user's business assurance documents and send it to the terminal device for the user to view. The interactivity and real-time performance are good, which can meet the user's need for real-time perception of the effectiveness of business assurance.

[0099] As one implementation method, prior to step 301 above, the policy control device also sends instruction information to the analysis data storage device. This instruction information instructs the received service assurance documents to be saved. Based on the received instruction information, the analysis data storage device saves the user's service assurance documents received from the network data analysis device. This allows the device to generate a service assurance report for the user based on the saved service assurance documents and send the report to the policy control device upon receiving a request message from the policy control device. Based on this method, by sending instruction information to the analysis data storage device to save the received service assurance documents, the analysis data storage device can accurately determine which service assurance documents need to be saved, facilitating the correct generation of the service assurance report.

[0100] The following describes two different methods for the strategy control device to send instruction information to the analysis data storage device.

[0101] In the first implementation method, the policy control device sends the aforementioned instruction information to the analysis data storage device through the interface between the policy control device and the analysis data storage device (or by calling the service of the analysis data storage device).

[0102] Based on this first implementation method, the strategy control device can directly send the aforementioned instruction information to the analysis data storage device, which is relatively efficient.

[0103] For example, before sending the aforementioned instruction information to the analysis data storage device, the policy control device further determines whether a user's control plane session has been established and the user's service assurance subscription process has been completed. If a user's control plane session has been established and the user's service assurance subscription process has been completed, the address information of the analysis data storage device is determined based on the user's identifier, and then the aforementioned instruction information is sent to the analysis data storage device based on the address information of the analysis data storage device. Based on this method, when a user's control plane session has been established and the user's service assurance subscription process has been completed, sending the aforementioned instruction information to the analysis data storage device by the policy control device can ensure that the analysis data storage device can correctly receive and save the user's service assurance documents.

[0104] This includes establishing a user's control plane session, such as establishing an Nx session between the user's mobility management network element (e.g., AMF network element) and policy control device (e.g., PCF network element), and establishing an Nz session between the user's policy control device and service operation device.

[0105] The process of completing the user's service assurance subscription includes, for example, the following operations: The policy control device sends a subscription request message to the network data analysis device. This message includes the user's identifier and a subscription event, which indicates that the user's quality of service (QoS) should be analyzed. The network data analysis device then sends a subscription request message to a session management network element (e.g., an SMF network element). This message includes the user's identifier, the network data analysis device's address information, and the subscription event, which also indicates that the user's QoS should be analyzed. The session management network element then sends a subscription request message to a user plane network element (e.g., a UPF network element). This message includes the user's identifier, the network data analysis device's address information, and the subscription event, which again indicates that the user's QoS should be analyzed. Subsequently, the user plane network element can report the pre-assistance KPI information for at least one application of the user to the network data analysis device based on the address information of the network data analysis device. This allows the network data analysis device to generate a service assurance document for the user based on the received pre-assistance KPI information for at least one application.

[0106] In the second implementation method, the policy control device sends a first message to the network data analysis device. This first message is either a subscription request message or a subscription update message. The first message includes the user's identifier, a subscription event, and the aforementioned indication information. The subscription event indicates that the user's quality of service should be analyzed. The network data analysis device then sends the aforementioned indication information to the analysis data storage device.

[0107] Based on this second implementation method, the control strategy device first sends the aforementioned instruction information to the network data analysis device, and then the network data analysis device sends the aforementioned instruction information to the analysis data storage device. On the one hand, the network data analysis device can, based on the instruction information, know that the analysis data storage device needs to save the received service guarantee document of the user, thereby triggering the network data analysis device to report the user's service guarantee document to the analysis data storage device, which helps the analysis data storage device to correctly obtain the user's service guarantee document. On the other hand, the strategy control device sends the instruction information to the network data analysis device by carrying it in the subscription request message or subscription update message, which can reuse the subscription request message or subscription update message of the existing technology without using a new message to carry the instruction information, thus reducing signaling overhead.

[0108] For example, the above Figure 3 The method implementation examples can be applied to the following application scenarios: Application Scenario 1: Individual User Package Experience Perception. Mobile network operator package users (such as silver and gold card users) can check at any time via mobile application (APP) the number of times they have enjoyed network acceleration protection, the duration of protection, and the speed improvement within a specific period of the month. Its value lies in improving users' perception of paid value-added services, enhancing user stickiness, and providing data basis for package renewal or upgrade.

[0109] Application Scenario 2: Enterprise Leased Line Service Quality Monitoring. In the leased line or high-quality network assurance services provided to enterprise customers, enterprise administrators can query network assurance reports for specific lines or user groups in real time to understand the achievement of service level agreements. Its value lies in facilitating internal network resource management and cost accounting for enterprises, and also providing service quality certification for operators.

[0110] Application Scenario 3: Network Optimization Effectiveness Evaluation. Network operations and maintenance departments can generate service assurance reports for specific regions or service types to evaluate the actual effectiveness of network optimization strategies (such as key service assurance strategies). Its value lies in providing data support for network planning and optimization, enabling precise investment.

[0111] Application Scenario 4: Customer Service Support and Dispute Resolution. When a user complains that network quality or service assurance is not up to expectations, customer service personnel can access the user's real-time service assurance report to objectively demonstrate the actual service situation using data. This helps in problem localization and customer communication, improving customer service efficiency and the fairness of dispute resolution.

[0112] The following is combined Figures 5 to 7 The above is given Figure 3 Specific examples of method implementations.

[0113] Figure 5This is a flowchart illustrating a communication method provided in an embodiment of this application. In this embodiment, the terminal, PCF network element, UPF network element, service operation equipment, NWDAF network element, and ADRF network element are respectively the aforementioned Figure 3 Specific examples of the terminal device, policy control device, user plane network element, service operation device, network data analysis device, and analysis data storage device in the method embodiments are provided. Furthermore, the PCF network element, UPF network element, NWDAF network element, and ADRF network element are abbreviated as PCF, UPF, NWDAF, and ADRF, respectively. The method includes the following steps: Step 500: The terminal registers with the network and completes the establishment of Nx and Nz sessions.

[0114] The Nx session is the control plane session between the AMF and the PCF, while the Nz session is the control plane session between the PCF and the service operation equipment.

[0115] Among them, terminal registration is the network, which can be understood as the user on the terminal registering to the network.

[0116] Step 501: The PCF sends a subscription request message to the NWDAF. Correspondingly, the NWDAF receives the subscription request message.

[0117] The subscription request message includes the user's identifier, subscription event, and indication information, and optionally, a PDU session identifier. The subscription event is for QoS analysis of the user. The indication information is used to instruct the user to save the received service assurance documents.

[0118] For example, after determining that the user has signed up for a service protection package, the PCF sends the aforementioned subscription request message to the NWDAF.

[0119] For example, when a PDU session is activated, the PCF sends the aforementioned subscription request message to the NWDAF.

[0120] For example, when a PDU session is activated, the PCF sends the aforementioned subscription request message to the NWDAF after determining that the user has subscribed to a service guarantee package.

[0121] Step 502: NWDAF sends a request message to ADRF. Correspondingly, ADRF receives the request message.

[0122] The request message includes the user's identifier and instruction information, and optionally, a PDU session identifier. This instruction information is used to instruct the received service assurance document to be saved.

[0123] Step 503: Continue to complete the remaining steps of the business assurance subscription process.

[0124] Step 504a: The UPF sends the pre-guarantee KPI information for at least one of the user's applications to the NWDAF. Correspondingly, the NWDAF receives the pre-guarantee KPI information for at least one of the user's applications.

[0125] UPF monitors the user's service quality in real time. When it detects a decline in service quality or the service experience monitoring cycle has ended, it reports the collected pre-assistance KPI information for at least one application of that user to NWDAF. The pre-assistance KPI information for an application may include at least one of the following: latency, packet loss rate, bandwidth, stuttering rate, or speed.

[0126] Among them, poor service quality refers to poor service quality. For example, if at least one of the following conditions is met, it indicates poor service quality: latency is less than the latency threshold, packet loss rate is less than the packet loss rate threshold, and lag rate is greater than the lag rate threshold.

[0127] Step 504b: NWDAF triggers the user's business assurance process and generates the user's business assurance document based on the pre-assistance KPI information of at least one of the user's applications.

[0128] For example, if NWDAF determines that service protection for the user is required based on the pre-protection KPI information of at least one of the user's applications, and determines that the user's service can be protected based on the current radio resources, then the user's service protection process is triggered, such as establishing a protection bearer (also known as a dedicated bearer) to transmit the user's service data.

[0129] For information on the contents of the business support document, please refer to [link / reference]. Figure 3 Description of the method embodiments.

[0130] In step 504c, the NWDAF sends the user's service assurance document to the ADRF. Correspondingly, the ADRF receives the user's service assurance document.

[0131] Step 505: ADRF saves the user's business assurance document according to the instruction information.

[0132] This instruction is the one received in step 502. This instruction is used to instruct the received business assurance document to be saved.

[0133] Step 506: The PCF sends a subscription request message to the service operation equipment. Correspondingly, the service operation equipment receives the subscription request message.

[0134] The subscription request message includes the user's identifier and the subscription event, which is a terminal query for a service assurance report.

[0135] Step 507: The terminal sends a third request message to the service operation equipment. Correspondingly, the service operation equipment receives the third request message.

[0136] The third request message includes the user's identifier and is used to request a service assurance report from the user.

[0137] For example, when a user operates a terminal and clicks the "Query Protection Report" button, the terminal is triggered to send the third request message to the business operation equipment.

[0138] Step 508: The service operation equipment sends a first request message to the PCF. Correspondingly, the PCF receives the first request message.

[0139] The first request message includes the user's identifier and is used to request the user's business assurance report.

[0140] Specifically, after receiving the first request message, the business operation equipment determines to send the first request message to the PCF based on the subscription request message received in step 506, in order to request the user's business assurance report.

[0141] In step 509, the PCF sends a second request message to the ADRF. Correspondingly, the ADRF receives the second request message.

[0142] The second request message includes the user's identifier and is used to request a service assurance report from the user.

[0143] The PCF can determine the ADRF's address information based on the user's identifier.

[0144] Step 510: ADRF generates a user's business assurance report based on the saved user's business assurance documents.

[0145] For information on the contents of the business assurance report, please refer to [link / reference]. Figure 3 Description of the method embodiments.

[0146] As one implementation method, statistical rules for service assurance reports can be pre-configured for ADRF. These rules specify the statistical period, such as daily, weekly, or monthly. Accordingly, in step 510, the service assurance report generated by ADRF for the user can be a service assurance report matching this statistical period.

[0147] As another implementation method, the statistical time range selected by the user can also be carried in the third request message of step 507 above. Correspondingly, the statistical time range is carried in the first request message of step 508 and the second request message of step 509. Thus, in step 510, the service assurance report generated by ADRF for the user can be a service assurance report that matches the statistical time range.

[0148] Step 511: ADRF sends the user's service assurance report to PCF. Correspondingly, PCF receives the user's service assurance report.

[0149] Step 512: The PCF sends the user's service assurance report to the service operation equipment. Correspondingly, the service operation equipment receives the user's service assurance report.

[0150] Step 513: The service operation equipment sends the user's service assurance report to the terminal. Correspondingly, the terminal receives the user's service assurance report.

[0151] Optionally, step 514 is also included, where the terminal displays the user's service assurance report.

[0152] Once the terminal receives the user's service assurance report, it can display the report on the user interface for the user to view.

[0153] Based on the above solution, users can query the business assurance report corresponding to the business assurance package in real time. ADRF can generate business assurance reports in real time and feed them back to users through business operation equipment. It has good timeliness and convenient interaction, which can meet users' needs for real-time perception of the effectiveness of business assurance.

[0154] Figure 6 This is a flowchart illustrating a communication method provided in an embodiment of this application. In this embodiment, the terminal, PCF network element, UPF network element, service operation equipment, NWDAF network element, and ADRF network element are respectively the aforementioned Figure 3 Specific examples of the terminal device, policy control device, user plane network element, service operation device, network data analysis device, and analysis data storage device in the method embodiments are provided. Furthermore, the PCF network element, UPF network element, NWDAF network element, and ADRF network element are abbreviated as PCF, UPF, NWDAF, and ADRF, respectively. The method includes the following steps: Step 600: The terminal is registered to the network, the PDU session is activated, and the user's service guarantee subscription process has been completed.

[0155] Terminal registration is a network process; it can be understood as a user on a terminal registering with the network.

[0156] The process of completing the user's service assurance subscription includes, for example, the following operations: The PCF sends a subscription request message to the NWDAF, which includes the user's identifier and a subscription event indicating that the user's service quality should be analyzed; the NWDAF sends a subscription request message to the SMF, which includes the user's identifier, the NWDAF's address information, and the subscription event indicating that the user's service quality should be analyzed; the SMF sends a subscription request message to the UPF, which includes the user's identifier, the NWDAF's address information, and the subscription event indicating that the user's service quality should be analyzed. Subsequently, the UPF can report the pre-assistance KPI information of at least one application of the user to the NWDAF based on the NWDAF's address information, so that the NWDAF can generate the user's service assurance document based on the received pre-assistance KPI information of at least one application of the user.

[0157] Step 601: Complete the establishment of Nx and Nz sessions.

[0158] The Nx session is the control plane session between the AMF and the PCF, while the Nz session is the control plane session between the PCF and the service operation equipment.

[0159] In step 602, the PCF sends a subscription update message to the NWDAF. Correspondingly, the NWDAF receives the subscription update message.

[0160] This subscription update message includes the user's identifier, the subscription event, and instruction information. The subscription event indicates that the user's service quality should be analyzed. The instruction information is used to instruct the saving of received service assurance documents.

[0161] Step 603: NWDAF sends a request message to ADRF. ADRF then receives the request message.

[0162] The request message includes the user's identifier and instruction information, and optionally, a PDU session identifier. This instruction information is used to instruct the received service assurance document to be saved.

[0163] Steps 604a to 614 are the same. Figure 5 Steps 504a to 514 of the method embodiment.

[0164] Based on the above solution, users can query the business assurance report corresponding to the business assurance package in real time. ADRF can generate business assurance reports in real time and feed them back to users through business operation equipment. It has good timeliness and convenient interaction, which can meet users' needs for real-time perception of the effectiveness of business assurance.

[0165] Figure 7This is a flowchart illustrating a communication method provided in an embodiment of this application. In this embodiment, the terminal, PCF network element, UPF network element, service operation equipment, NWDAF network element, and ADRF network element are respectively the aforementioned Figure 3 Specific examples of the terminal device, policy control device, user plane network element, service operation device, network data analysis device, and analysis data storage device in the method embodiments are provided. Furthermore, the PCF network element, UPF network element, NWDAF network element, and ADRF network element are abbreviated as PCF, UPF, NWDAF, and ADRF, respectively. The method includes the following steps: Step 700: The terminal is registered to the network, the PDU session is activated, and the user's service guarantee subscription process has been completed.

[0166] Terminal registration is a network process; it can be understood as a user on a terminal registering with the network.

[0167] The process of completing the user's service assurance subscription includes, for example, the following operations: The PCF sends a subscription request message to the NWDAF, which includes the user's identifier and a subscription event indicating that the user's service quality should be analyzed; the NWDAF sends a subscription request message to the SMF, which includes the user's identifier, the NWDAF's address information, and the subscription event indicating that the user's service quality should be analyzed; the SMF sends a subscription request message to the UPF, which includes the user's identifier, the NWDAF's address information, and the subscription event indicating that the user's service quality should be analyzed. Subsequently, the UPF can report the pre-assistance KPI information of at least one application of the user to the NWDAF based on the NWDAF's address information, so that the NWDAF can generate the user's service assurance document based on the received pre-assistance KPI information of at least one application of the user.

[0168] Step 701: Complete the establishment of Nx and Nz sessions.

[0169] The Nx session is the control plane session between the AMF and the PCF, while the Nz session is the control plane session between the PCF and the service operation equipment.

[0170] In step 702, if the PCF determines that a user's control plane session has been established and the user's service assurance subscription process has been completed, then it determines the ADRF's address information based on the user's identifier.

[0171] The establishment of a user's control plane session refers to the completion of the establishment of the Nx and Nz sessions.

[0172] In step 703, the PCF sends a request message to the ADRF based on the ADRF's address information. The ADRF then receives the request message.

[0173] The request message includes the user's identifier and instruction information. This instruction information is used to instruct the user to save the received service assurance document. Optionally, the request message may also include a PDU session identifier.

[0174] In step 704a, the UPF sends the pre-guarantee KPI information for at least one of the user's applications to the NWDAF. Correspondingly, the NWDAF receives the pre-guarantee KPI information for at least one of the user's applications.

[0175] UPF monitors the user's service quality in real time. When it detects a decline in service quality or the service experience monitoring cycle has ended, it reports the collected pre-assistance KPI information for at least one application of that user to NWDAF. The pre-assistance KPI information for an application may include at least one of the following: latency, packet loss rate, bandwidth, stuttering rate, or speed.

[0176] Among them, poor service quality refers to poor service quality. For example, if at least one of the following conditions is met, it indicates poor service quality: latency is less than the latency threshold, packet loss rate is less than the packet loss rate threshold, and lag rate is greater than the lag rate threshold.

[0177] Step 704b: NWDAF triggers the user's business assurance process and generates the user's business assurance document based on the pre-assistance KPI information of at least one of the user's applications.

[0178] For example, if NWDAF determines that service protection for the user is required based on the pre-protection KPI information of at least one of the user's applications, and determines that the user's service can be protected based on the current radio resources, then the user's service protection process is triggered, such as establishing a protection bearer (also known as a dedicated bearer) to transmit the user's service data.

[0179] For information on the contents of the business support document, please refer to [link / reference]. Figure 3 Description of the method embodiments.

[0180] In step 704c, ADRF sends a request message to NWDAF. Correspondingly, NWDAF receives the request message.

[0181] The request message includes the user's identifier and is used to request the user's business assurance document.

[0182] In step 704d, the NWDAF sends the user's service assurance document to the ADRF. Correspondingly, the ADRF receives the user's service assurance document.

[0183] Steps 705 to 714 are the same. Figure 5 Steps 505 to 514 of the method embodiment.

[0184] Based on the above solution, users can query the business assurance report corresponding to the business assurance package in real time. ADRF can generate business assurance reports in real time and feed them back to users through business operation equipment. It has good timeliness and convenient interaction, which can meet users' needs for real-time perception of the effectiveness of business assurance.

[0185] The above primarily describes the solutions provided by the embodiments of this application from the perspective of the interaction between the strategy control device, the analysis and data storage device, the network data analysis device, the business operation device, and the terminal device. It is understood that, in order to achieve the above functions, the strategy control device, the analysis and data storage device, the network data analysis device, the business operation device, and the terminal device may include corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, in conjunction with the units and algorithm steps of the various examples described in the embodiments disclosed herein, the embodiments of this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0186] This application embodiment can divide the strategy control device, analysis and data storage device, network data analysis device, business operation device, and terminal device into functional units based on the above method examples. For example, each function can be divided into its own functional unit, or two or more functions can be integrated into one unit. The integrated unit can be implemented in hardware or as a software functional unit.

[0187] When using integrated units, Figure 8 A possible exemplary block diagram of the apparatus involved in an embodiment of this application is shown. For example... Figure 8 As shown, the communication device 800 may include a processing unit 802 and a communication unit 803. The processing unit 802 is used to control and manage the operation of the communication device 800. The communication unit 803 is used to support communication between the communication device 800 and other devices. Optionally, the communication unit 803, also called a transceiver unit, may include a receiving unit and / or a transmitting unit, respectively used to perform receiving and transmitting operations. The communication device 800 may also include a storage unit 801 for storing the program code and / or data of the communication device 800.

[0188] The communication device 800 can be the strategy control device in the above embodiments. The processing unit 802 can support the communication device 800 in executing the actions of the strategy control device in the above method embodiments. Alternatively, the processing unit 802 mainly executes the internal actions of the strategy control device in the method embodiments, and the communication unit 803 can support communication between the communication device 800 and other devices.

[0189] In one embodiment, the communication unit 803 is configured to: receive a first request message from a service operation device, the first request message including a user identifier, the first request message requesting a service assurance report from the user, the service assurance report indicating the effectiveness of quality assurance for the user's service, the service operation device serving a terminal device corresponding to the user; send a second request message to an analysis data storage device, the second request message including a user identifier, the second request message requesting the service assurance report; receive the service assurance report from the analysis data storage device, the service assurance report being determined based on the user's service assurance document; and send the service assurance report to the service operation device.

[0190] As one possible implementation, the communication unit 803 is also configured to send instruction information to the analysis data storage device before receiving the first request message from the business operation device, the instruction information being used to instruct the received business assurance document to be saved.

[0191] As one possible implementation, the communication unit 803 is specifically used to send a first message to the network data analysis device. The first message is a subscription request message or a subscription update message. The first message includes the user's identifier, a subscription event, and the indication information.
