Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, and in particular to a service guarantee mark display method and device, equipment, medium and program product. BACKGROUND

[0002] With the development of network intelligence, differentiated experience operation has gradually become mainstream. While providing service guarantee (such as quality difference guarantee, etc.) for users, operators can make users more intuitively perceive the existence of guarantee by regulating and controlling terminal individualization marks. Without terminal mark prompts, users cannot intuitively perceive whether the operator guarantees the service, and cannot clearly understand the effect of the guarantee.

[0003] The existing scheme can only issue left marks based on user granularity individualization, and cannot accurately issue different mark strategies corresponding to whether there is service guarantee. Therefore, the user's perception experience granularity is relatively rough, and the user cannot intuitively and real-time perceive that the service guarantee is being performed. SUMMARY

[0004] Therefore, it is necessary to provide a service guarantee mark display method, device, equipment, medium and program product to enable users to intuitively perceive that the service guarantee is being performed.

[0005] In a first aspect, the present application provides a service guarantee mark display method applied to a NWDAF network element, comprising:

[0006] receiving a first service guarantee event notification message sent by a user plane function UPF network element; wherein the first service guarantee event notification message is sent by the UPF network element based on monitoring of occurrence of a target service after sending a service guarantee subscription message, and the service guarantee subscription message is sent by the NWDAF network element to the UPF network element based on a service guarantee request for the target service sent by a policy control function PCF network element;

[0007] In the case where it is determined that the target service occurs according to the first service guarantee event notification message, and it is determined that the target service needs to be guaranteed according to network resource information, a service guarantee mechanism for the target service is triggered, and the first service guarantee event notification message is sent to a policy control function PCF network element, so that the PCF network element informs an access and mobility management function AMF network element to display a guarantee mark of the target service at the user end.

[0008] In one of the embodiments, the first service guarantee event notification message includes a user identifier of a target user subscribing to the target service, a service identifier of the target service, and an event identifier representing whether the target service occurs; and the determination of the occurrence of the target service according to the first service guarantee event notification message comprises:

[0059] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0060] The service assurance identifier display method provided in this application embodiment can be applied to, for example, Figure 1In the application environment shown, the AMF (Access and Mobility Management Function) network element 101 is responsible for user equipment authentication, authorization, registration, mobility management, and connection management; the PCF (Policy Control Function) network element 102 is responsible for access management and policy control, as well as session management and policy control; the NWDAF (Network Data Analytics Function) network element 103 is used to collect and analyze data and provide valuable results to service providers; and the UPF (User Plane Function) network element 104 is responsible for routing and forwarding user plane data packets, and can also realize data and service identification, action and policy execution, and other functions. Optionally, NWDAF network element 103 receives a first service assurance event notification message sent by UPF network element 104; wherein, the first service assurance event notification message is sent by UPF network element 104 after monitoring the occurrence of the target service based on the service assurance subscription message, and the service assurance subscription message is sent by NWDAF network element 103 to UPF network element 104 based on the service assurance request for the target service sent by policy control function PCF network element 102; if it is determined that the target service has occurred according to the first service assurance event notification message, and it is determined according to network resource information that the target service needs to be guaranteed, the service assurance mechanism for the target service is triggered, and the first service assurance event notification message is sent to PCF network element 102, so that PCF network element 102 informs access and mobility management function AMF network element 101 to display the guarantee identifier of the target service on the user terminal.

[0061] In one exemplary embodiment, such as Figure 2 As shown, a method for displaying a service assurance identifier is provided, which can be applied to... Figure 1 Taking NWDAF element 103 as an example, the explanation includes the following steps:

[0062] S201, Receive the first service assurance event notification message sent by the user plane function UPF network element.

[0063] Among them, the first service assurance event notification message is sent by the UPF network element after monitoring the occurrence of the target service based on the service assurance subscription message. The service assurance subscription message is sent by the NWDAF network element to the UPF network element based on the service assurance request for the target service sent by the PCF network element based on the policy control function.

[0064] It should be noted that when users use services provided by operators (such as communication services, network services, data services, etc.), a series of safeguards are taken to ensure the stability, reliability, and security of the services and to meet the reasonable needs of users. To ensure that users can intuitively perceive that the service is being protected, a service guarantee icon needs to be displayed on the user's page; this icon can be located in the upper left corner of the page.

[0065] Furthermore, if a user requires service assurance display for a specific service, they need to pre-subscribe to the service assurance display service. Specifically, the user can sign up for service assurance through the application provided by the operator. The user's service assurance subscription information will be stored in the business operation support system, including user identifier, service identifier, subscription time, and other information. After the user completes the subscription, the business operation support system will send the service assurance display policy for the target service subscribed to by the user to the PCF network element. Further, the PCF network element will generate a service assurance subscription request, which includes the service identifier and user identifier. The PCF network element will send the service assurance subscription request to the NWDAF network element. The NWDAF network element will generate a service assurance subscription message based on the service assurance subscription request and send the service assurance subscription message to the UPF network element, so that the UPF network element can monitor whether the service has occurred in real time based on the service identifier and user identifier.

[0066] If the UPF network element detects that the target service has occurred, it will generate a first service assurance event notification message. The first service assurance event notification message includes, but is not limited to, the user identifier of the target user who subscribed to the target service, the service identifier of the target service, and an event identifier indicating whether the target service has occurred. The event identifier is identified by 1 or 0, where 1 indicates that the target service has occurred and 0 indicates that the target service has not occurred.

[0067] UPF network elements can periodically send first service assurance event notification messages to NWDAF network elements, or they can send first service assurance event notification messages to NWDAF network elements when they detect a change in the status of the target service.

[0068] S202, if it is determined that the target service has occurred based on the first service assurance event notification message, and it is determined based on the network resource information that the target service needs to be guaranteed, the service assurance mechanism for the target service is triggered, and the first service assurance event notification message is sent to the PCF network element, so that the PCF network element informs the Access and Mobility Management Function (AMF) network element to display the guarantee identifier of the target service on the user terminal.

[0069] It should be noted that service assurance for the target service is only potentially necessary if the target service occurs. However, after confirming the occurrence of the target service, it is still necessary to determine whether assurance is required. If assurance is required, it must be provided, and a service assurance indicator should be displayed during the assurance process. The service assurance mechanism refers to the sum of a series of rules, processes, technical means, and organizational systems established to ensure the stable, efficient, and secure operation of the target service and its continuous fulfillment of user needs. The first service assurance event notification message includes the user identifier of the target user subscribing to the target service, the service identifier of the target service, and an event identifier indicating whether the target service has occurred.

[0070] Optionally, the occurrence of a target service can be determined based on the event identifier contained in the first service assurance event notification message. If the target service has occurred, the network status and the operation of the target service can be monitored in real time to obtain network resource information. If the network resource information detects that poor network conditions are causing the target service to lag, it can be determined that the target service needs to be guaranteed. For example, if the event identifier is a first preset value, it is determined that the target service has occurred; wherein, the first preset value represents the occurrence of the target service, for example, the first preset value is 1.

[0071] Once the target service is determined to meet the guarantee conditions, the NWDAF network element will trigger a service guarantee mechanism for the target service. Specifically, the NWDAF network element can determine the service guarantee strategy and initiate the service guarantee process based on the detected network status or abnormal situations occurring in the target service. For example, it may obtain radio statistics data from the OAM, predict the current cell load, trigger GBR guarantee to the SM-PCF, and inform the AM-PCF that service guarantee exists.

[0072] At the same time, the NWDAF network element will forward the first service guarantee event notification message to the PCF network element, so that the PCF network element can inform the AMF network element to display the guarantee identifier of the target service on the user end.

[0073] In the aforementioned service assurance identifier display method, a first service assurance event notification message is received from the User Plane Function (UPF) network element. This first service assurance event notification message is sent by the UPF network element after monitoring the occurrence of the target service based on a service assurance subscription message. The service assurance subscription message is sent by the NWDAF network element to the UPF network element based on a service assurance request for the target service sent by the Policy Control Function (PCF) network element. When it is determined that the target service has occurred based on the first service assurance event notification message, and it is determined based on network resource information that the target service requires assurance, a service assurance mechanism for the target service is triggered, and the first service assurance event notification message is sent to the PCF network element. This allows the PCF network element to inform the Access and Mobility Management Function (AMF) network element to display the assurance identifier for the target service on the user terminal. This scheme, by introducing an interaction process for displaying the service assurance identifier among the NWDAF, PCF, AMF, and UPF network elements, can provide users with a timely and accurate service assurance identifier display function for the target service during the service assurance period, allowing users to intuitively perceive that they are being served.

[0074] Furthermore, it should be noted that after a user stops the target service, or after the target service is no longer guaranteed, the display of the service guarantee indicator needs to be canceled to improve the user experience and the accuracy of the service guarantee indicator display. Specifically, if a second service guarantee event notification message is received from the UPF network element, and it is determined based on the second service guarantee event notification message that the target service has stopped, or it is determined based on network resource information that the target service does not need to be guaranteed, then the service guarantee mechanism for the target service is stopped, and a second service guarantee event notification message is sent to the PCF network element, so that the PCF network element informs the AMF network element to stop displaying the guarantee indicator of the target service on the user end.

[0075] It should be noted again that PCF network elements generally include AM-PCF (Access and Mobility Management Policy Control Function) and SM-PCF (Session Management Policy Control Function) network elements. AM-PCF network elements primarily provide access control and mobility management policies to the Access and Mobility Management Function, and can also provide policies to user equipment. SM-PCF network elements are responsible for providing policy control for session management-related services, such as policy formulation and execution during the establishment, modification, and release of PDU sessions. The deployment methods for AM-PCF and SM-PCF network elements include co-location and separate deployment. If the deployment method is co-location, then the AM-PCF and SM-PCF network elements can be regarded as a single PCF network element, and the interaction between the AM-PCF and SM-PCF network elements is completed within the PCF network element itself.

[0076] If the AM-PCF network element and the SM-PCF network element are deployed separately, the service assurance request is sent by the SM-PCF network element to the NWDAF network element based on the service assurance subscription information sent by the AM-PCF network element. The service assurance subscription information is obtained by the AM-PCF network element from the business operation support system. At the same time, the SM-PCF network element sends a first service assurance event notification message to the PCF network element so that the PCF network element can inform the AMF network element of the access and mobility management function to display the assurance identifier of the target service on the user terminal. The method is to send a first service assurance event notification message to the SM-PCF network element so that the SM-PCF network element can forward the first service assurance event notification message to the AM-PCF network element, and the AM-PCF network element can inform the AMF network element to display the assurance identifier of the target service on the user terminal.

[0077] In one exemplary embodiment, such as Figure 3 As shown, a method for displaying a service assurance identifier is provided, which can be applied to... Figure 1 Taking PCF network element 102 as an example, the explanation includes the following steps:

[0078] S301 receives the first service assurance event notification message sent by the NWDAF network element.

[0079] Specifically, the first service assurance event notification message is sent by the NWDAF network element after determining that the target service has occurred based on the first service assurance event notification message received from the UPF network element, and after determining that the target service needs to be guaranteed based on network resource information and triggering the service assurance mechanism for the target service. The first service assurance event notification message sent by the UPF network element is sent by the UPF network element after monitoring the occurrence of the target service based on the service assurance subscription message. The service assurance subscription message is sent by the NWDAF network element to the UPF network element based on the service assurance request for the target service sent by the PCF network element.

[0080] S302, Based on the first service assurance event notification message, generate a service assurance display policy for the target service.

[0081] Among them, the service guarantee display strategy should include at least the service identifier of the target service.

[0082] Understandably, if a user requires service assurance display for a specific service, they need to pre-subscribe to the service assurance display service. Specifically, the user can sign up for service assurance through the application provided by the operator. The user's service assurance subscription information will be stored in the business operation support system, including user identifier, service identifier, subscription time, and other information. After the user completes the subscription, the business operation support system will send the service assurance display policy for the target service subscribed to by the user to the PCF network element.

[0083] Furthermore, after receiving the first service assurance event notification message sent by the NWDAF network element, the PCF network element can look up the service assurance display policy corresponding to the user identifier and service identifier based on the user identifier and service identifier.

[0084] S303 sends the service assurance display policy to the AMF network element so that the AMF network element can display the service assurance identifier of the target service on the user terminal.

[0085] Optionally, the PCF network element will send the service guarantee display policy to the AMF network element, and the AMF network element will display the service guarantee identifier on the user terminal according to the service guarantee display policy.

[0086] Furthermore, when the NWDAF network element recognizes that the service assurance identifier for the target service does not need to be displayed, it sends a second service assurance event notification message to the PCF network element. If the NWDAF network element receives this second service assurance event notification message, it instructs the AMF network element to stop displaying the target service's assurance identifier on the user end. This second service assurance event notification message is sent by the NWDAF network element after receiving it from the UPF network element and determining that the target service is stopped based on the message, or after determining from network resource information that the target service does not require assurance. Upon receiving the second service assurance event notification message, the UPF network element sends a notification message to the AMF network element indicating that the service assurance identifier display has been cancelled, which includes both the user identifier and the service identifier. The AMF network element then stops displaying the target service's assurance identifier on the user end.

[0087] In this embodiment, after receiving the first service assurance event notification message from the NWDAF network element, the PCF network element generates a service assurance display policy for the target service based on the first service assurance event notification message, and sends the service assurance display policy to the AMF network element so that the AMF network element can display the service assurance identifier of the target service on the user terminal. In this scheme, the PCF network element can accurately obtain the service assurance display policy for the target service based on the first service assurance event notification message, and further send the service assurance display policy to the AMF network element, ensuring the timeliness and accuracy of the display of the service assurance identifier for the target service.

[0088] Optionally, since the AM-PCF network element and the SM-PCF network element are deployed separately, steps S301-S303 in the above embodiments are executed by the AM-PCF network element and the SM-PCF network element respectively. In this case, in an exemplary embodiment, as follows: Figure 4 As shown, a method for displaying service assurance identifiers is provided. Taking the application of this method to an AM-PCF network element as an example, the method includes the following steps:

[0089] S401, Receive the first service assurance event notification message forwarded by the SM-PCF network element.

[0090] Specifically, the first service assurance event notification message is sent by the NWDAF network element to the SM-PCF network element after determining that the target service has occurred based on the first service assurance event notification message received from the UPF network element, and after determining that the target service needs to be guaranteed based on network resource information and triggering the service assurance mechanism for the target service. The first service assurance event notification message sent by the UPF network element is sent by the UPF network element after monitoring the occurrence of the target service based on the service assurance subscription message. The service assurance subscription message is sent by the NWDAF network element to the UPF network element based on the service assurance request for the target service sent by the PCF network element.

[0091] Optionally, the NWDAF network element sends a first service assurance event notification message to the SM-PCF network element, which then forwards the message to the AM-PCF network element. At this point, the AM-PCF network element can receive the first service assurance event notification message forwarded by the SM-PCF network element.

[0092] S402, Based on the first service assurance event notification message, generate a service assurance display policy for the target service.

[0093] Among them, the service guarantee display strategy should include at least the service identifier of the target service.

[0094] If a user requires service assurance display for a specific service, they need to pre-subscribe to the service assurance display service. Specifically, the user can sign up for service assurance through the application provided by the operator. The user's service assurance subscription information will be stored in the business operation support system, including user identifier, service identifier, subscription time, and other information. After the user completes the subscription, the business operation support system will send the service assurance display policy for the target service subscribed to by the user to the AM-PCF network element.

[0095] Furthermore, after receiving the first service assurance event notification message sent by the NWDAF network element, the AM-PCF network element can look up the service assurance display policy corresponding to the user identifier and service identifier based on the user identifier and service identifier.

[0096] S403 sends the service assurance display policy to the AMF network element so that the AMF network element can display the service assurance identifier of the target service on the user terminal.

[0097] In this embodiment, after receiving the first service assurance event notification message forwarded by the SM-PCF network element, the AM-PCF network element generates a service assurance display policy for the target service based on the first service assurance event notification message; and sends the service assurance display policy to the AMF network element so that the AMF network element displays the service assurance identifier of the target service on the user end. This scheme, by introducing AM-PCF and SM-PCF network elements separately and deploying them separately, reduces the burden on the PCF network element and ensures the efficiency and accuracy of the process of displaying the service assurance identifier of the target service.

[0098] Optionally, in an exemplary embodiment, such as Figure 5 As shown, a method for displaying service assurance identifiers is provided. Taking the application of this method to an SM-PCF network element as an example, the method includes the following steps:

[0099] S501 receives the first service assurance event notification message sent by the NWDAF network element.

[0100] Specifically, the first service assurance event notification message is sent by the NWDAF network element after determining that the target service has occurred based on the first service assurance event notification message received from the UPF network element, and after determining that the target service needs to be guaranteed based on network resource information and triggering the service assurance mechanism for the target service. The first service assurance event notification message sent by the UPF network element is sent by the UPF network element after monitoring the occurrence of the target service based on the service assurance subscription message. The service assurance subscription message is sent by the NWDAF network element to the UPF network element based on the service assurance request for the target service sent by the PCF network element.

[0101] S502, forward the first service assurance event notification message to the AM-PCF network element, so that the AM-PCF network element can inform the AMF network element to display the service assurance identifier of the target service on the user end.

[0102] In this embodiment, after receiving the first service assurance event notification message sent by the NWDAF network element, the SM-PCF forwards the message to the AM-PCF network element, so that the AM-PCF network element informs the AMF network element to display the service assurance identifier of the target service on the user end. This solution, by introducing and deploying AM-PCF and SM-PCF network elements separately, reduces the burden on the PCF network element and ensures the efficiency and accuracy of displaying the service assurance identifier of the target service.

[0106] S603, the SM-PCF network element sends a service assurance subscription message to the NWDAF network element based on the service assurance subscription information.

[0107] S604, the NWDAF network element sends a service guarantee subscription message to the UPF network element.

[0108] S605, the UPF network element monitors the occurrence of the target service based on the service assurance subscription message, and sends the first service assurance event notification message to the NWDAF network element when the target service is detected to have occurred.

[0109] S606, when the NWDAF network element determines that the target service has occurred based on the first service assurance event notification message and determines that the target service needs to be guaranteed based on the network resource information, it triggers the service assurance mechanism for the target service and sends the first service assurance event notification message to the SM-PCF network element.

[0110] S607, the SM-PCF network element forwards the first service guarantee event notification message to the AM-PCF network element.

[0111] S608, the AM-PCF network element generates a service assurance display policy for the target service based on the notification message of the first service assurance event.

[0112] S609, the AM-PCF network element sends the service guarantee display policy to the AMF network element.
