Description

Background

In a general architecture of Network automation in a fifth generation mobile communication (5G) system, a Network Data analysis Function (NWDAF) is introduced into a core Network. The NWDAF is used as a bearer entity for customized data collection and intelligent analysis, can collect data from a Network Function (NF), an Application Function (AF), and Operation, Maintenance and Administration (OAM) of a 5G core Network (5GC), has intelligent analysis capabilities (such as calculation, training, inference, prediction, and the like), and outputs an analysis result to the NF, AF, or OAM for decision making by the NF, AF, or OAM.

In the existing scheme, the NWDAF data analysis capability may include intelligent capabilities of perception, learning, calculation, training, reasoning, prediction, decision, and the like, and the data analysis result is a result after NWDAF intelligent analysis. Currently, the types of analysis results that the default NWDAF can provide are registered in a Network storage Function (NRF), which is particularly suitable for offline training analysis and configuration. However, in practical applications, there may be an analysis result type of the NWDAF that is not registered in the NRF but only registered in the address of the NWDAF, such as online NWDAF training analysis, or an NWDAF that has locally loaded a related file (such as a machine learning algorithm file, a feature engineering algorithm file), but there is no actually supportable analysis result type.

As described in the background art, in the prior art, when an NWDAF does not register an analysis result type with an NRF, NF, AF, and OAM may not obtain a target NWDAF that can pass a relevant analysis result type through the NRF when it is desired to obtain an analysis result type that the NWDAF can provide, and thus it is difficult to request the relevant analysis result type from the target NWDAF.

To solve at least one of the above problems, embodiments of the present invention provide a method for providing a data analysis result, which may provide a type of an analysis result required by a consuming function when an NWDAF does not register the type of the analysis result. Referring to fig. 1, a method for providing a data analysis result according to an embodiment of the present invention, when applied to a certain NWDAF (for convenience of description, referred to as a first NWDAF), includes:

step 11, the first NWDAF receives a subscription requirement message of the data analysis result sent by the consuming function, where the subscription requirement message carries a first analysis result type to which the consuming function requests subscription.

Here, the first NWDAF may directly receive a subscription requirement message sent by the consuming function, where the subscription requirement message carries an analysis result type (for convenience of description, referred to as a first analysis result type) that the consuming function desires to obtain, and specifically, the consuming function may be an entity such as an AF, an NF, or an OAM. The subscription requirement message is used for indicating the requirements of the consuming function on a training model, an inference result, a prediction result and the like. The subscription requirement message carries a first analysis result type, and the analysis result type may be represented by an analysis ID, for example, the first analysis result type may be an analysis ID ═ MOS (representing QoE score) or an analysis ID ═ Abnormal Mobility Behavior (representing Abnormal Mobility Behavior), and the like. In addition to the first analysis result type (analysis ID, for example), the subscription requirement message may also carry a performance metric index requirement, a time requirement, a location requirement, a user identity, and the like.

And step 12, the first NWDAF performs requirement analysis and model management according to the subscription requirement message, and determines whether a service corresponding to the first analysis result type can be provided.

Here, after receiving the subscription requirement message, the first NWDAF may determine, through requirement analysis and model management, whether or not it can provide a service corresponding to the first analysis result type, and further determine how to respond to the subscription requirement message. Specifically, the first NWDAF may determine whether the service can be provided through processes such as requirement analysis and mapping, runtime environment analysis, feature selection analysis, and data source analysis.

And step 13, the first NWDAF sends a service response message to the consuming function according to whether the service corresponding to the first analysis result type can be provided.

Here, where a service corresponding to the first analysis result type can be provided, the first NWDAF may send a service response message of service confirmation to the consuming function to indicate that the first NWDAF can provide the corresponding service; conversely, the first NWDAF may send a service response message of service rejection to the consuming function to indicate that the first NWDAF is unable to provide the corresponding service.

Through the above steps, the embodiment of the present invention realizes that the consuming function directly sends the subscription requirement message to the first NRDAF, so that even if the first NRDAF does not register its analysis result type on the NRF, a service response message for service confirmation can be sent to the consuming function, and a corresponding service can be provided for the consuming function subsequently, thereby solving the problem that it is difficult to provide a service to the consuming function when the NRDAF does not register the analysis result type on the NRF in the prior art.

In this embodiment of the present invention, when the first NWDAF determines that the service corresponding to the first analysis result type can be provided, the first NWDAF may further send a service registration request message of the data analysis result to the NRF, where the service registration request message carries the first analysis result type. Optionally, the service registration request message may further carry information such as parameters, computational power, performance metric index values, and the like of the relevant model. In this way, when a subsequent NRF receives a certain consuming function and queries an NWDAF that can provide a service corresponding to the first analysis result type, it may provide information such as an address of the first NWDAF to the consuming function, so as to provide the consuming function with a relevant service.

In the embodiment of the present invention, when the first NWDAF determines that the service corresponding to the first analysis result type can be provided, the first NWDAF may also initiate a data acquisition subscription to a corresponding data source, obtain related source data, and perform intelligent analysis to obtain a first data analysis result; then, the first NWDAF may send a first notification message of the data analysis result to the consuming function in step 11, where the first notification message carries a first data analysis result (such as a training model, an inference result, a prediction result, and the like), so as to provide a corresponding service to the consuming function.

In practical applications, data of the data source may be updated and changed, which may result in an update of the data analysis result, and may also result in that the first NWDAF may no longer provide relevant services to the consuming function.

In the above scenario, the embodiment of the present invention may update the data analysis result according to the change of the data source. Specifically, the first NWDAF may receive characteristic update information sent by the data source after the characteristic update occurs, perform demand analysis and model management according to the characteristic update information, and determine whether to continue to provide a service corresponding to the first analysis result type; under the condition that the service corresponding to the first analysis result type can be continuously provided, acquiring updated data of the data source and carrying out intelligent analysis to obtain an updated second data analysis result; and then sending a second notification message of the data analysis result to the consuming function, wherein the second notification message carries the second data analysis result.

Further, when it is determined that the service corresponding to the first analysis result type can be continuously provided, the first NWDAF may further send a service update message of the data analysis result to the NRF, where the service update message carries the first analysis result type and update content of the service analysis result, and is used to update the related information stored on the NRF.

When determining that the service corresponding to the first analysis result type cannot be provided continuously, the first NWDAF may send a service termination request message of the data analysis result to the consuming function, where the service termination request message carries the first analysis result type; and sending a service deregistration request message of the data analysis result to the NRF, wherein the service deregistration request message carries the first analysis result type, thereby stopping providing the relevant service for the consuming function and canceling the relevant registration information of the first NWDAF on the NRF.

In addition, in a scenario where a relevant service cannot be provided continuously due to the end of a model lifecycle, the first NWDAF according to the embodiment of the present invention may further send, to the consuming function, a service cancellation notification message of the data analysis result, send, to the NRF, a service deregistration request message of the data analysis result, and send, to the data source, a subscription cancellation message of data acquisition, where the service cancellation notification message, the service deregistration request message, and the subscription cancellation message all carry the first analysis result type, when the lifecycle of the training model corresponding to the data analysis result is ended. Through the above processing, the embodiment of the present invention may stop providing the consuming function with the relevant service and cancel the relevant registration information of the first NWDAF on the NRF when the life cycle of the model is finished.

Through the steps, the embodiment of the invention solves the problem that the NWDAF is lack of management on the intelligent analysis result when the NWDAF capability is not registered in the prior art, provides a specific solution for the requirement mapping, model management, model updating and optimization, analysis result aging and analysis result transmission between consumption function entities (such as NF, AF good OAM and the like) of the NWDAF, expands the function of the NWDAF in the prior art, and solves the problem that the prior art is difficult to provide related services under the condition.

The method for providing the data analysis result according to the embodiment of the present invention is explained above from the NWDAF side. Further description is made below from the consuming functional entity side.

Referring to fig. 2, a method for providing a data analysis result according to an embodiment of the present invention may be applied to a consuming function side, where the consuming function may specifically be an entity such as AF, NF, or OAM, as shown in fig. 2, where the method includes:

step 21, the consuming function sends a subscription requirement message of the data analysis result to the first NWDAF, where the subscription requirement message carries the first analysis result type to which the consuming function requests subscription.

Here, the consuming function may send a subscription requirement message to the first NWDAF when desiring to obtain a service corresponding to the first analysis result class. The subscription requirement message carries the first analysis result type, and may also carry information such as performance metric index requirement, time requirement, location requirement, and user identity.

Step 22, the consuming function receives a service response message sent by the first NWDAF, where the service response message is used to indicate whether the first NWDAF can provide the service corresponding to the first analysis result type.

Here, after receiving the service response message sent by the first NWDAF, the consuming function may determine whether the first NWDAF can provide the service corresponding to the first analysis result type, for example, when the service response message indicates service confirmation, it indicates that the first NWDAF can provide the service corresponding to the first analysis result type, and when the service response message indicates service rejection, it indicates that the first NWDAF cannot provide the service corresponding to the first analysis result type.

Through the above steps, the embodiment of the present invention realizes that the consuming function directly sends the subscription requirement message to the first NWDAF, so that even if the first NWDAF does not register the analysis result type thereof on the NRF, the consuming function can directly send the service response message for service confirmation to the first NWDAF, thereby acquiring the corresponding service, and solving the problem that it is difficult to provide the service to the consuming function when the NWDAF does not register the analysis result type on the NRF in the prior art.

In this embodiment of the present invention, before step 21, the consuming function may further send a service discovery request message to the NRF, where the service discovery request message is used to request information of a target NWDAF that can provide a data analysis result of the first analysis result type. In a case where the NRF is unable to provide the target NWDAF to the consuming function, the consuming function may determine a first NWDAF according to a preset condition, and then proceed to step 21, and send a subscription requirement message of a data analysis result to the first NWDAF. Here, the preset condition may be preconfigured NWDAF information, for example, information that the consuming function is preconfigured with more than one NWDAF, such as address information, so that, in a case that the NRF cannot provide the target NWDAF, the consuming function may select a certain NWDAF (i.e., the first NWDAF) from the preconfigured NWDAFs and send the subscription requirement message to the certain NWDAF.

According to at least one embodiment of the present invention, in the case that the service response message in step 22 indicates that the first NWDAF can provide the service corresponding to the first analysis result type, the consuming function may further receive a first notification message of the data analysis result sent by the first NWDAF, where the first notification message carries a first data analysis result (such as a training model, an inference result, a prediction result, and the like).

After the characteristic of the data source of the first NWDAF performing the data analysis is updated, if the first NWDAF may further continue to provide the service corresponding to the first analysis result type, the consuming function may further receive a second notification message of the data analysis result sent by the first NWDAF, where the second notification message carries the second data analysis result, and the second data analysis result is a data analysis result newly generated by the first NWDAF after the characteristic of the corresponding data source is updated,

after the characteristic of the data source for performing data analysis by the first NWDAF is updated, if the first NWDAF cannot continue to provide the service corresponding to the first analysis result type, at this time, the consuming function may further receive a service termination request message of the data analysis result sent by the first NWDAF, where the service termination request message carries the first analysis result type. In this way, the consuming function may determine, from the service termination request message, that the first NWDAF cannot continue to be served for it.

In addition, when the life cycle of the training model corresponding to the data analysis result is completed, the consuming function may further receive a service cancellation notification message of the data analysis result sent by the first NWDAF, where the service cancellation notification message carries the first analysis result type, and thus, the consuming function may determine, according to the service cancellation notification message, that the first NWDAF cannot continue to serve the consuming function.

The methods of the embodiments of the present invention are described above from the NWDAF and the consuming function side, respectively. The above method will be further described below by way of an example of an interaction flow between entities.

Referring to fig. 3, in an example of the method for providing a data analysis result according to the embodiment of the present invention, the consuming function may be an entity such as NF, AF, or OAM, and the data source may also be an entity such as NF, AF, or OAM. As shown in fig. 3, this example includes:

NWDAF registers only NWDAF address and service Tracking Area (TA) area in NRF, and does not register specific intelligent service capability, i.e., does not register intelligent analysis result type (here, type field may be represented by analysis ID).

301. The consuming function (Consumer), which may be specifically an NF/AF/OAM entity, sends a subscription requirement of the intelligent analysis result to the NWDAF, where the subscription requirement may be specifically a requirement such as a training model, an inference result, a prediction result, and the like. Here, the subscription requirement includes an analysis ID, such as an analysis ID (MOS (QoE score) or an analysis ID (Abnormal Mobility Behavior), and may further include information such as a performance metric requirement, a time requirement, a location requirement, and a user identity.

The NWDAF starts requirement judgment and model management according to the requirement of a Consumer, and comprises the following steps: requirement analysis and mapping, running environment analysis, feature selection analysis, data source analysis and the like.

And 303a, if the service corresponding to the analysis ID can be provided according to the result of model management, the NWDAF confirms the service to the Consumer (indicating that the related intelligent analysis service is supported). If the NWDAF cannot provide the service corresponding to the Analytics ID, the NWDAF rejects the Consumer (indicating that the relevant intelligent analysis service is not supported), and may carry rejection reasons (such as that the performance metric index cannot be satisfied, the calculation power is insufficient, and the data source characteristics cannot be satisfied).

And 303bc, if the nwdaf can provide the service corresponding to the analysis ID, the nwdaf can also initiate a service registration message required by the intelligent analysis result to the NRF, wherein the message comprises information such as the analysis ID, the analysis type (such as online or offline), the model parameter, the calculation capacity, the performance metric index value and the like.

The conditioner returns a confirmation response and/or a cancel analysis result subscription message to the NWDAF corresponding to whether the NWDAF can provide the service in step 303a.

Through the above steps 301 to 303, the present example can solve the problem that, when the analysis result type of the NWDAF in the prior art is not registered in the NRF, the NF, the AF, or the OAM cannot obtain the required intelligent analysis through the NWDAF.

And 304, initiating Data acquisition subscription to related Data sources (Data providers), such as NF/AF/OAM and the like, by the NWDAF according to the Data source analysis result managed by the model, and acquiring related Data.

NWDAF performs intelligent analysis, such as model training, reasoning, prediction, etc.

The NWDAF notifies the Consumer of the results of the intelligent analysis (e.g., training models, reasoning results, prediction results, performance metric values, etc.).

Here, steps 304-306 can be performed with reference to prior art implementations.

307-308, if the characteristics of the data source are updated, such as the service experience requirement update of the APP application, the user movement rule update, the user number update, the user flow update, the NF deployment update and the like, the NWDAF acquires new data.

And 309, comparing data characteristics and data sources, judging requirements or managing models according to the newly acquired data by the NWDAF, and referring to the step 302.

And 309a, if the data source characteristics can still meet the requirements of the Consumer on the analysis ID after being updated, performing new evaluation and correction of intelligent data analysis according to the time period and/or the conditions of data source updating and the like, wherein the new evaluation and correction comprise evaluation and update of a training model (such as a QoE model, a mobile model and the like).

And 309b, if the data source characteristics do not meet the requirement of the Consumer on the analysis ID after being updated, the NWDAF initiates a service termination request to the Consumer, wherein the request can comprise the analysis ID and a termination reason.

309c, if the data source characteristics do not meet the requirement of the Consumer on the analysis ID after being updated, the NWDAF sends a service de-registration message to the NRF, and the message carries the analysis ID so as to perform service de-registration of the analysis ID.
