[0090] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0091] With the rapid development of the communications industry, differentiated user experiences have become mainstream. When providing services to users, operators are expected to provide higher-quality resource guarantees for VIP high-end users and make the presence of application services more intuitive to users. Therefore, providing service guarantees through the core network has broad market prospects.

[0092] Currently, the rights and interests corresponding to the user levels of various types of operators' users (including ordinary users and VIP users) are mainly managed through the Access and Mobility Policy Control Function (AM-PCF) in the core network, and this rights and interests information is transmitted to the user terminal so that users can be informed of their privileges.

[0093] However, when a user uses a service and a benefit within that service, the AM-PCF cannot detect whether the benefit is being used by a service. Therefore, it cannot manage the information and resource policies related to the benefit during the service usage process, resulting in the user being unable to perceive information about the service during use. This application aims to provide a service perception method for user terminals that enables user terminal perception at the service level to address the above issues.

[0094] After introducing the background technology of the service perception method of the user terminal provided by the embodiment of the present application, the following briefly describes the implementation environment involved in the service perception method of the user terminal provided by the embodiment of the present application. The service perception method of the user terminal provided by the embodiment of the present application can be applied to Figure 1 In the core network shown, the core network includes the access and mobility management function (AMF), the policy control function (PCF), the session management function (SMF) and the user plane function (UPF).

[0095] The Policy Control Function (PCF) can be further divided into the Access and Mobility Policy and Charging Function (AM-PCF) and the Session Management Policy and Charging Function (SM-PCF). AM-PCF and SM-PCF can be deployed together or separately. The PCF is primarily responsible for access management and policy control. The AM-PCF, through interaction with the AMF, provides access and mobility management-related policies and issues service-level control policies to the AMF. The SM-PCF, on the other hand, is primarily responsible for session management and policy control. It interacts with the SMF to provide session management-related policies.

[0096] Among them, AMF can trigger the establishment of N15 session between AM-PCF, support policy control such as left display label to user equipment (UE) through N1 interface according to business requirements, and implement service-level base station policy control to intelligent base station (Radio Access Network, RAN) through N2 interface to achieve wireless resource guarantee.

[0097] Among them, the functions of SMF include session establishment, modification and release, etc. It can subscribe to business flow events from the intelligent UPF and support the selection of a specific intelligent UPF based on the special identifier signed by the PCF.

[0098] Among them, PCF supports data packet routing and forwarding, packet detection, etc., supports business identification and business need guarantee identification and reporting, etc.

[0099] The network elements of the above-mentioned core network interact with each other through information. When the UPF sends a notification message of the occurrence of a service flow event to the UE based on the target service flow event indicated by the user terminal ID and application ID, it ensures that the UE can accurately perceive the occurrence of the target service flow event and improve the user experience.

[0100] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0101] In one embodiment, a service perception method for a user terminal is provided. Figure 1 The UPF in is used as an example to illustrate. Figure 2 As shown, the following steps are included:

[0102] S201. Upon receiving a service flow subscription message sent by a policy and charging function (PCF), monitor multiple service flow events forwarded by the local device. The service flow subscription information includes a user terminal ID and an application ID.

[0103] Among them, service flow events refer to the data communication services running on each user terminal, which can include video streaming services, voice call services, web browsing services, etc.

[0104] It should be noted that the multiple service flow events mentioned in this embodiment refer to multiple service flow events corresponding to the user terminal ID, for example, video streaming service, voice call service, web browsing service, etc. running on the terminal corresponding to the user terminal ID.

[0105] In this embodiment, when the PCF receives a subscription to a target service (for example, user terminal a subscribes to a membership of a certain video software A), it generates service flow subscription information based on the subscription information of the target service (for example, user terminal a and video software A), and forwards the service flow subscription information to the UPF. After the UPF receives the service flow subscription information sent by the PCF, it triggers the monitoring device installed on the local machine to monitor multiple service flow events corresponding to the user terminal ID forwarded by the local machine.

[0106] S202. If a target service flow event indicated by the user terminal ID and application ID is monitored, a service flow event occurrence notification message is sent to the PCF. The service flow event occurrence notification message includes the user terminal ID, application ID and occurrence identifier of the target service flow event.

[0107] In this embodiment, the target business flow event corresponding to the user terminal ID and application ID can be obtained by screening among multiple business flow events forwarded by the local machine according to the user terminal ID and application ID, and a business flow event occurrence notification message is generated according to the occurrence identifier of the target business flow event, the user terminal ID and the application ID, and the business flow event occurrence notification message is sent to the PCF.

[0108] In this embodiment, if the target business flow event corresponding to the user terminal ID and application ID is not obtained when screening among multiple business flow events forwarded by the local machine based on the user terminal ID and application ID, the step of sending a business flow event occurrence notification message to the PCF will not be executed and the process will be ended directly.

[0109] In an embodiment of the present application, upon receiving a service flow subscription message sent by PCF, it is determined whether a target service flow event occurs based on the service flow subscription information, and when the target service flow event occurs, a service flow event occurrence notification message carrying the user terminal ID, application ID and the occurrence identifier of the target service flow event is sent to PCF to achieve user terminal perception at the user level and service level. Compared with the existing method in which only AMF and AM-PCF interaction is used to achieve user terminal perception only at the user level, the present application enables the user terminal to perceive information of the service during use, thereby ensuring the user terminal's service perception when the service occurs.

[0110] In one embodiment, in the above Figure 2 Based on the examples, Figure 3 As shown, the process of sending the service flow event occurrence notification message to the PCF can be described, that is, the above "if the target service flow event indicated by the user terminal ID and the application ID is detected, the service flow event occurrence notification message is sent to the PCF", including:

[0111] S301: Obtain feature codes corresponding to multiple monitored business flow events.

[0112] In this embodiment, when multiple service flow events forwarded by the local device are monitored, feature codes corresponding to the multiple service flow events can be obtained. It should be noted that different service flow events correspond to different feature codes, different user terminal IDs also correspond to different feature codes, and different application IDs also correspond to different feature codes. In other words, the feature code corresponding to a service flow event can be composed of the application ID, user terminal ID, and identification information of the service flow event.

[0113] Optionally, feature codes corresponding to multiple business flow events can be stored in a feature library. After monitoring multiple business flow events forwarded by the local machine, feature codes corresponding to each business event can be queried from the feature library.

[0114] S302: Match the user terminal ID and the application ID with the feature codes corresponding to the multiple business flow events.

[0115] In this embodiment, after obtaining the feature codes corresponding to the multiple business flow events, the feature codes corresponding to the multiple business flow events can be matched based on the user terminal ID and the application ID.

[0116] For example, the monitored service flow events include video streaming and voice call services. The feature code corresponding to the video streaming service is 123.234.456 (where 123 is the user terminal ID, 234 is the application ID, and 456 is the identification information for the video streaming service), and the feature code corresponding to the voice call service is 123.245.567 (where 123 is the user terminal ID, 245 is the application ID, and 567 is the identification information for the voice call service). If the user terminal ID is 123 and the application ID is 234, then 123.234 matches the feature code 123.234.456 and the feature code 123.245.567, resulting in the feature code 123.234.456 matching 123.234.

[0117] S303: If there is a feature code matching the user terminal ID and the application ID among the feature codes corresponding to the multiple service flow events, a service flow event occurrence notification message is sent to the PCF.

[0118] In this embodiment, when there is a feature code matching the user terminal ID and application ID among the feature codes corresponding to multiple business flow events, the occurrence identifier, user terminal ID and application ID of the target business flow event can be determined based on the identification information of the target business flow event corresponding to the matching feature code, a business flow event occurrence notification message can be generated, and the business flow event occurrence notification message can be sent to PCF.

[0119] Continuing with the previous example, after obtaining the feature code 123.234.456 that matches 123.234, the identification information of the target business flow event in the matching feature code 123.234.456 is determined (i.e., 456), the occurrence identification 4561 of the target business flow event is generated, and based on the occurrence identification 4561 of the target business flow event, the user terminal ID 123, and the application ID 234, a business flow event occurrence notification message is generated (the message carries: 123.234.4561), and the business flow event occurrence notification message is sent to the PCF.

[0120] In an embodiment of the present application, the user terminal ID and the application ID are used to match the feature codes corresponding to the multiple business flow events. If the match is successful, a business flow event occurrence notification message carrying the occurrence identifier of the business flow event is generated, and the business flow event occurrence notification message is fed back to the PCF to achieve user terminal perception at the business level.

[0121] In one embodiment, in the above Figure 2 Based on the examples, Figure 4 As shown, after sending the service flow event occurrence notification message to the PCF, the above method further includes:

[0122] S203. When the target service flow event is monitored to have stopped, a service flow event stop notification message is sent to the PCF; the service flow event stop notification message includes the user terminal ID, the application ID and the stop identifier of the target service flow event.

[0123] In this embodiment, after sending a service flow event occurrence notification message to PCF, UPF will monitor the target service flow event in real time. When monitoring that the target service flow event has stopped, it will generate a stop mark of the target service flow event, and generate a service flow event stop notification message based on the user terminal ID, application ID and the stop mark of the target service flow event, and send the service flow event stop notification message to PCF.

[0124] Continuing with the previous example, after the UPF detects that the target business flow event corresponding to the feature code 123.234.456 has stopped, it determines the identification information of the target business flow event in the matching feature code 123.234.456 (i.e., 456), generates the stop identifier 4560 of the target business flow event, and generates a business flow event stop notification message (the message carries: 123.234.4560) based on the stop identifier 4560 of the target business flow event, the user terminal ID 123, and the application ID 234, and sends the business flow event stop notification message to the PCF.

[0125] In an embodiment of the present application, when the target business flow event is monitored to stop, a business flow event stop notification message carrying the user terminal ID, application ID and stop identifier of the target business flow event is sent to the PCF to achieve efficient perception of the user terminal at the user level and business level.

[0126] In one embodiment, a service perception method for a user terminal is provided, such as Figure 5 As shown, this method is applied to Figure 1 The PCF in the example is used to illustrate the process, which includes the following steps:

[0127] S401. When receiving a target service subscription request from a user management system, generate service flow subscription information corresponding to the target service; the service flow subscription information includes a user terminal ID and an application ID.

[0128] Among them, the user management system can be a business operation support system (Business & Operation Support System, BOSS).

[0129] In this embodiment, when BOSS receives the target service signed by the user, it will sign the target service with PCF. After PCF signs the target service, it can generate business flow subscription information corresponding to the target service.

[0130] For example, when BOSS receives the rights and interests of a user terminal to register a certain video software, it will sign the rights and interests information of the user terminal and the corresponding video software to PCF. After PCF signs the rights and interests information of the user terminal and the corresponding video software, it generates business flow subscription information based on the rights and interests information of the user terminal and the corresponding video software, that is, generates the user terminal ID and application ID.

[0131] S402: Send the service flow subscription information to the user plane function network element UPF.

[0132] In this embodiment, after the service flow subscription information is generated, the service flow subscription information can be sent to the UPF, so that the UPF executes the above steps S201-S203 and S301-S302 to complete the service event perception of the user terminal.

[0133] S403. Receive a service flow event occurrence notification message sent by the UPF; the service flow event occurrence notification message includes the user terminal ID, the application ID, and the occurrence identifier of the target service flow event.

[0134] In this embodiment, after the UPF filters out the target business flow event from multiple monitored business flow events based on the business flow subscription information, it can generate a business flow event occurrence notification message based on the user terminal ID and application ID in the business flow subscription information, and the occurrence identifier corresponding to the target business flow event, and send the business flow event notification message to the PCF, so that the PCF receives the business flow event occurrence notification message sent by the UPF.

[0135] In an embodiment of the present application, upon receiving a service flow subscription message sent by PCF, it is determined whether a target service flow event occurs based on the service flow subscription information, and when the target service flow event occurs, a service flow event occurrence notification message carrying the user terminal ID, application ID and the occurrence identifier of the target service flow event is sent to PCF to achieve user terminal perception at the user level and service level. Compared with the existing method in which only AMF and AM-PCF interaction is used to achieve user terminal perception only at the user level, the present application enables the user terminal to perceive information of the service during use, thereby ensuring the user terminal's service perception when the service occurs.

[0136] In one embodiment, in the above Figure 5 Based on the examples, Figure 6 As shown, the above method also includes:

[0137] S404.

[0149] S408. Send the event stop notification policy to the access and mobility management function network element AMF.

[0150] In this embodiment, after the event stop notification policy is generated as described above, the event stop notification policy can be sent to the AMF, so that the AMF forwards the event stop notification policy to the UE to ensure effective perception of the user terminal at the service level.

[0151] In one embodiment, a service perception method for a user terminal is provided. Figure 8 , this method is applied to Figure 1 The AMF in the example is used to illustrate, including the following steps:

[0152] S501. Receive an event occurrence notification policy sent by a policy and charging function network element PCF; the event occurrence notification policy includes identification information of a target service flow event.

[0153] In this embodiment, when the PCF sends an event occurrence notification policy to the AMF, the AMF receives the event occurrence notification policy sent by the PCF.

[0154] S502: Generate a service terminal control request according to the event occurrence notification policy; the service terminal control request includes the user terminal ID and identification information of the target service flow event.

[0155] In this embodiment, when an event occurrence notification policy is received, a service terminal control request including the user terminal ID and identification information of the target service flow event is generated according to the event occurrence notification policy.

[0156] It should be noted that a service terminal control request will be generated whether the user terminal has not subscribed to the high-level service in advance or the user terminal has subscribed to the high-level service in advance.

[0157] S503: Send the service terminal control request to the user terminal.

[0158] In this embodiment, after the service terminal regulation request is generated, the service terminal regulation request may be sent to the user terminal.

[0159] It should be noted that after the service terminal control request is sent to the user terminal, the user terminal will also generate service terminal control reply information after performing local control according to the service terminal control request, and send the service terminal control reply information to AMF, so that AMF receives the service terminal control reply information sent by the user terminal.

[0160] In an embodiment of the present application, upon receiving a service flow subscription message sent by PCF, it is determined whether a target service flow event occurs based on the service flow subscription information, and when the target service flow event occurs, a service flow event occurrence notification message carrying the user terminal ID, application ID and the occurrence identifier of the target service flow event is sent to PCF to achieve user terminal perception at the user level and service level. Compared with the existing method in which only AMF and AM-PCF interaction is used to achieve user terminal perception only at the user level, the present application enables the user terminal to perceive information of the service during use, thereby ensuring the user terminal's service perception when the service occurs.

[0161] In one embodiment, in the above Figure 8 Based on the examples, Figure 9 As shown, when the event occurrence notification strategy also includes wireless resource guarantee information, the above method further includes:

Therefore, the AMF can send a radio resource guarantee request to the base station RAN where the user terminal is located, so that the base station RAN allocates corresponding resources to the user terminal to ensure high-quality operation of the user terminal when running the target service flow event.

[0164] It should be noted that after sending the wireless resource guarantee request to the RAN, the RAN will also generate resource control response information after performing local control based on the wireless resource guarantee request, and send the resource control response information to the AMF, so that the AMF receives the resource control response information sent by the RAN.

[0165] In an embodiment of the present application, when the event occurrence notification strategy also includes wireless resource guarantee information, a wireless resource guarantee request is also sent to the base station RAN to enable the RAN to ensure high-quality operation of the target service flow event in the user terminal.

[0169] S602. Send a service terminal control request reply message to the AMF.

[0170] In this embodiment, when the service terminal regulation request reply message is generated above, the service terminal regulation request reply message can be sent to the AMF so that the AMF can perceive the regulation situation of the user terminal stopping the notification message according to the service flow event.

[0171] In this embodiment, when a service flow subscription message sent by PCF is received, whether the target service flow event occurs is determined based on the service flow subscription information, and when the target service flow event occurs, a service flow event occurrence notification message carrying the user terminal ID, application ID and the occurrence identifier of the target service flow event is sent to PCF to achieve user terminal perception at the user level and service level. Compared with the existing method in which only AMF and AM-PCF interaction is used to achieve user terminal perception only at the user level, this application enables the user terminal to perceive information of the service during use, thereby ensuring the user terminal's service perception when the service occurs.
