Description

Technical Field

[0001] This application relates to the field of mobile communication technology, specifically to a policy management method, apparatus, computer device, and storage medium. Background Technology

[0002] With the development of mobile communication technology, operators, in order to optimize mobile networks, are not only pursuing important directions such as network function upgrades and network speed improvements, but also further considering the flexibility and practicality of policy management. Taking home-based subscription as an example, after a user terminal completes its subscription, the AMF (Access and Mobility Management Function) network element and the PCF (Policy Control Function) network element establish policy associations (e.g., AM (Access and Mobility) policy associations). However, the deletion of policy associations corresponding to home-based subscriptions is triggered by re-login or location updates. Even if the home-based subscription plan has ended, because the user terminal's location has not been updated or the operation has been offline and then re-login, the AM policy association cache for that user terminal will still be retained in the AMF and PCF network elements, occupying the capacity of the AM policy association. This leads to the problem of network resources not being released in a timely manner and low effective resource utilization. Therefore, how to achieve flexible policy management that can both release invalid network resources in a timely manner and meet the service needs of different subscribed services is a critical problem that urgently needs to be solved. Summary of the Invention

[0003] Therefore, it is necessary to provide a strategy management method, apparatus, computer equipment, and storage medium that enables flexible strategy management in response to the above-mentioned technical problems.

[0016] In one embodiment, the target management strategy is determined based on the triggering method and / or the termination method in the service termination message, including:

[0017] When the triggering method is "move to target area" and the termination method in the service termination message is "the contracted resources have been used up", the target management strategy is determined to include the second display update strategy.

[0018] In one embodiment, the policy association for managing target terminals is based on a target management policy, including:

[0019] A second display update policy is sent to the AMF network element so that the AMF network element displays the second identifier on the target terminal based on the second display update policy, and retains the policy association; wherein, the second identifier is used to indicate that the subscribed resources have been used up.

[0020] Secondly, this application provides a policy management device configured in a PCF network element, the device comprising:

[0021] The first determining module is used to determine the service type of the subscribed service in response to the service termination message sent by the detection end for the subscribed service of the target terminal.

[0022] The second determination module is used to determine the target management strategy based on the business type;

[0023] The management module is used to manage the policy associations of target terminals based on the target management policy; wherein, the policy association is the policy association located between the AMF network element and the PCF network element and associated with the contracted service.

[0024] Thirdly, this application also provides a computer device, which includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to perform the following steps:

[0025] In response to the service termination message sent by the detection end for the subscribed service of the target terminal, the service type of the subscribed service is determined;

[0026] Determine the target management strategy based on the type of business;

[0027] Based on the target management strategy, the strategy association of the target terminal is managed; where the strategy association is located between the AMF network element and the PCF network element and is associated with the contracted service.

[0036] The aforementioned policy management method, apparatus, computer equipment, and storage medium, in response to a service termination message for a subscribed service sent by the detection end to a target terminal, determine the service type of the subscribed service. Based on the service type, a target management policy is determined. Based on the target management policy, the policy association of the target terminal is managed; wherein, the policy association is a policy association located between the AMF network element and the PCF network element and associated with the subscribed service.

[0044] 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.

[0045] With the development of mobile communication technology, operators, in order to optimize mobile networks, are not only pursuing important directions such as network function upgrades and network speed improvements, but also further considering the flexibility and practicality of policy management. Taking home-based subscription as an example, after a user terminal completes the subscription, the AMF (Access and Mobility Management Function) network element and the PCF (Policy Control Function) network element establish a policy association (e.g., AM (Access and Mobility) policy association). However, the deletion of the policy association corresponding to the home-based subscription is triggered by re-login or location update. Even if the home-based subscription plan has ended (i.e., the subscription service has ended), because the user terminal's location has not been updated or the operation has been offline and then re-login, the AM policy association cache of the user terminal will still be retained in the AMF and PCF network elements, occupying the capacity of the AM policy association. This leads to the problem that network resources cannot be released in a timely manner and the effective resource utilization rate is low. For example, consider a temporary subscription service customized for a museum. When the AMF (Agency Management Function) network element detects a user terminal entering the subscription service's associated area, it establishes an AM policy association with the local PCF (Public Security Function) network element. This allows the PCF network element to immediately send the corresponding display policy to the AMF network element through the associated channel after the user scans the code, providing the subscription service. However, once the subscription service's corresponding package expires, the AM association policy is deleted. This results in a situation where, in a temporary subscription scenario, the user hasn't left the associated area and wants to renew the service, but scanning the code again lacks the corresponding channel to send the policy, preventing renewal. Therefore, achieving flexible policy management that promptly releases invalid network resources while meeting the service needs of different subscription services is a crucial challenge that urgently needs to be addressed.

[0046] The strategy management method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, when the detection terminal detects the termination of the subscribed service of the target terminal, it sends a service termination message to the PCF network element. The PCF network element responds to the service termination message sent by the detection terminal for the subscribed service of the target terminal and determines the service type of the subscribed service. Based on the service type, the PCF network element determines the target management policy. Based on the target management policy, the PCF network element manages the policy association of the target terminal. Here, the policy association is a policy association located between the AMF network element and the PCF network element, and associated with the subscribed service. In this application, the policy association is an AM policy association, a dynamic, one-to-one control channel established to serve the subscribed service of the target terminal.

[0047] Among them, the AMF (Access and Mobility Management Function) network element is responsible for user terminal authentication, authorization, registration, mobility management and connection management functions.

[0048] PCF (Policy Control Function) network elements support a unified policy framework to manage network behavior, provide policy rules for network entities to implement, and access subscription information from a unified data warehouse.

[0049] In one embodiment, Figure 2 This is a flowchart illustrating a strategy management method provided in an embodiment of this application, applied to... Figure 1 Taking the PCF network element as an example, this method includes the following steps:

[0050] S201, in response to the service termination message sent by the detection end for the subscribed service of the target terminal, determine the service type of the subscribed service.

[0051] In this context, the detection terminal refers to a device with contracted service detection capabilities. Optionally, in this embodiment, the detection terminal can be the operator's IT (Information Technology) system. The target terminal refers to the user terminal that requires policy control. The contracted service refers to a service contract signed between the user terminal and the operator. This could be a service package actively purchased by the user terminal (e.g., a high-speed, high-priority, 100GB data package), or a temporarily contracted service package (e.g., a data package usable locally or in a specific region (e.g., a museum, amusement park, etc.)). The service type refers to the type of contracted service.

[0052] Optionally, the service types in this embodiment mainly include home-based contracted services and temporary contracted services. Home-based contracted services refer to service packages subscribed to by the user terminal and the home network, and these generally have a longer duration. Temporary contracted services refer to service packages signed up temporarily, and generally have characteristics such as short duration and regional restrictions.

[0053] Optionally, in this embodiment, when the detection terminal detects the termination of the subscribed service, it sends a service termination message for the target terminal to the PCF network element. In this embodiment, the detection terminal can send the service termination message for the target terminal to the PCF network element directly or through other devices or network element devices.

[0054] One optional implementation method for determining the service type of a contracted service in this embodiment is to determine the service type based on a package list. The package list records the service types of various contracted services; therefore, the service type can be determined based on the contracted service.

[0055] Another optional implementation of determining the service type of the contracted service in this embodiment is to send a first query request for the contracted service to the query device, so that the query device can provide feedback on the service type of the contracted service to the PCF network element based on the first query request.

[0056] S202, Determine the target management strategy based on the business type.

[0057] Among them, the target management strategy refers to the management strategy associated with the contracted business.

[0058] As an optional implementation of this application, a target management strategy is determined based on a package list and service type. The package list stores the service type and management strategy for each contracted service.

[0059] Another optional implementation of this application involves performing a policy association update analysis on the business types, and determining the target management strategy based on the update analysis results. The update analysis results may include deletion, retention, etc.

[0060] Another optional implementation of this application is to send a second query request carrying a service type to the query device, so that the query device can feed back the target management strategy to the PCF network element based on the second query request.

[0061] S203 manages the policy associations of target terminals based on the target management strategy.

[0062] Among them, the policy association is the policy association located between the AMF network element and the PCF network element and associated with the contracted service.

[0063] Optionally, in this embodiment, a request message is generated based on the target management policy. The request message is sent to the AMF network element so that the AMF network element manages the policy association of the target terminal based on the request message.

[0064] The aforementioned policy management method, in response to a service termination message for a subscribed service sent by the detection end to the target terminal, determines the service type of the subscribed service. Based on the service type, a target management policy is determined. Based on the target management policy, the policy association of the target terminal is managed; wherein, the policy association is a policy association located between the AMF network element and the PCF network element and associated with the subscribed service. In this application, when the PCF network element receives a service termination message for a subscribed service to the target terminal, it can determine the target management policy based on the service type of the subscribed service and manage the policy association of the target terminal based on the target management policy. This improves the flexibility of policy association management, enabling timely release of invalid network resources and maintaining policy associations even when the subscribed service is a special service (e.g., a temporary subscribed service), reserving a channel for users to re-subscribe, meeting user needs, and improving user satisfaction.

[0065] In one embodiment, when the service type is a home-based contract service, the target management strategy is determined to include a first display update strategy and an association deletion strategy. Based on this, such as Figure 3 As shown, an optional implementation method for managing the policy association of target terminals based on the target management strategy includes:

[0066] S301, send the first display label update policy and the association deletion policy to the AMF network element, so that the AMF network element displays the first identifier on the target terminal based on the first display label update policy, and deletes the policy association based on the association deletion policy.

[0067] The first identifier indicates the termination of the subscribed service. The first identifier update policy is the policy used to update the displayed identifier on the target terminal. The association deletion policy is the policy used to instruct the AMF network element to delete the policy association of the subscribed service.

[0068] For example, user terminal A in a certain province purchases a "VIP Card for Display Services." After subscribing to this service on the PCF network element in that province, the user terminal will display "XX Operator VIP" and use the guaranteed data allowance provided by the VIP card. At this time, the AMF network element and the PCF network element have established an AM policy association for user terminal A. After the IT system detects that the VIP card has expired or the guaranteed data allowance has been used up, it notifies the PCF network element to delete the subscribed service for user terminal A and update the display. The PCF network element generates a first display update policy and an association deletion policy, and sends the first display update policy and the association deletion policy to the AMF network element, notifying the AMF to delete the AM policy association for the UE and update the display of user terminal A (e.g., from "XX Operator VIP" to "XX Operator").

[0069] In this embodiment, a first display label update policy and an association deletion policy are sent to the AMF network element. This enables the AMF network element to display a first identifier on the target terminal based on the first display label update policy, and to delete policy associations based on the association deletion policy. The first identifier indicates the termination of the subscribed service. Based on this embodiment, when the service type is a home-based subscription service, the AMF network element can display the first identifier on the target terminal based on the first display label update policy, and delete policy associations based on the association deletion policy. This not only achieves timely deletion of policy associations, releasing the network resources occupied by the policy associations, but also updates the display label on the target terminal in a timely manner based on the first display label update policy to display the first identifier, prompting the user that the subscribed service has terminated.

[0070] In one embodiment, when the business type is a temporary contract business, in order to determine the target management strategy, such as... Figure 4 As shown, based on the business type, the optional implementation methods for the target management strategy include:

[0071] S401, when the business type is temporary contract business, obtain the trigger method for establishing the strategy association of temporary contract business.

[0072] Among them, the triggering method refers to the triggering method for establishing a strategy association with the temporary contract business.

[0073] Optionally, in this embodiment, the triggering method includes triggering upon moving to the target area.

[0074] S402, determine the target management strategy based on the triggering method and / or the termination method in the service termination message.

[0075] The termination methods include the expiration of the contracted business or the exhaustion of the contracted resources corresponding to the contracted business.

[0076] Optionally, in this embodiment, when the triggering method is to move to the target area and the termination method in the service termination message is that the contracted resources have been used up, the target management strategy is determined to include the second display update strategy.

[0077] Based on the above embodiments, an optional implementation of the policy association for managing target terminals, based on the target management strategy, involves sending a second display update policy to the AMF network element. This causes the AMF network element to display a second identifier on the target terminal based on the second display update policy, while retaining the policy association. The second identifier indicates that the subscribed resources have been used up. For example, user B, whose home region is in the first region, enters the museum area in the second region. After entering the museum area, an AM policy association is established between the AMF network element and the PCF network element in the second region for user terminal B. User terminal B scans a code in the museum area to apply for a display service and subscribes to a temporary service on the PCF network element. The PCF network element sends a display policy to the AMF network element through the association channel of user terminal B. The AMF network element controls user terminal B to display "XX Museum" while enjoying the high-speed experience and data allowance of the package. When the data allowance expires, the IT system notifies the PCF to delete the temporary subscription service. The PCF network element generates a second display update policy and sends it to the AMF network element. The AMF network element controls user terminal B to update the display based on the second display update policy, displaying the second identifier. After seeing the second sign, the user, having not yet completed their visit, scanned the code again to request the sign display service. Because the AM policy association was previously retained, the PCF network element could still issue a sign display policy based on this AM policy association after the user re-scanned the code. After the user finished their visit and left the museum, the AMF network element initiated the deletion of the AM policy association for user terminal B.

[0078] In this embodiment, when the service type is a temporary subscription service, the triggering method for establishing the policy association of the temporary subscription service is obtained. Based on the triggering method and / or the termination method in the service termination message, the target management policy is determined, increasing the flexibility of the target management policy. When the service type is a temporary subscription service, based on the target management policy, the method for managing the policy association of the target terminal is to send a second display update policy to the AMF network element, so that the AMF network element displays a second identifier on the target terminal based on the second display update policy, and retains the policy association; wherein, the second identifier is used to indicate that the subscription resources have been used up. With the policy association retained, the user can continue to renew the temporary subscription service based on the retained policy association; the policy association is only deleted when the user leaves the target area.

[0079] In one embodiment, such as Figure 5 As shown, an optional implementation of a strategy management method includes:

[0080] S501, in response to the service termination message sent by the detection end for the subscribed service of the target terminal, determines the service type of the subscribed service.

[0081] S502, when the business type is a home-based contracted business, the target management strategy is determined to include the first display update strategy and the associated deletion strategy.

[0082] S503, a first display update policy and an association deletion policy are sent to the AMF network element, so that the AMF network element displays the first identifier on the target terminal based on the first display update policy, and deletes the policy association based on the association deletion policy. The first identifier is used to indicate the termination of the subscribed service.

[0083] S504, when the business type is temporary contract business, obtain the triggering method for establishing the strategy association of temporary contract business.

[0084] S505, when the triggering method is "move to target area trigger" and the termination method in the service termination message is "the contracted resources have been used up", the target management strategy is determined to include the second display update strategy.

[0085] S506, a second display update policy is sent to the AMF network element so that the AMF network element displays the second identifier on the target terminal based on the second display update policy, and retains the policy association. The second identifier is used to indicate that the subscribed resources have been used up.

[0086] The policy management method in this embodiment, in response to a service termination message for a subscribed service sent by the detection end to a target terminal, determines the service type of the subscribed service. Based on the service type, a target management policy is determined. Based on the target management policy, the policy association of the target terminal is managed; wherein, the policy association is a policy association located between the AMF network element and the PCF network element and associated with the subscribed service. In this application, when the PCF network element receives a service termination message for a subscribed service to a target terminal, it can determine the target management policy based on the service type of the subscribed service and manage the policy association of the target terminal based on the target management policy. This improves the flexibility of policy association management, enabling timely release of invalid network resources and maintaining policy associations even when the subscribed service is a special service (e.g., a temporary subscribed service), reserving a channel for users to re-subscribe, meeting user needs, and improving user satisfaction.
