In this embodiment, through the above steps, the network element of the core network can be used to send the analysis result of the NWDAF to the terminal, thereby improving the analysis performance of the terminal.

The method provided by the embodiment of the present application is illustrated by two examples below:

Embodiment one:

In this embodiment, the analysis result of subscribing to NWDAF by SMF instead of UE, as shown in Figure 5, includes the following steps:

Step 1: UE sends NAS message to SMF.

This step may be to add a trigger mechanism, specifically, when the UE has an NWDAF analysis result that needs to be subscribed to, a NAS message may also be triggered.

Wherein, the above NAS message includes an analysis container (Analytics Container), and this Container includes the information of the analysis result of the NWDAF that the UE wishes to subscribe to. It is also possible to directly carry the analysis result information of the NWDAF that the UE wishes to subscribe to in the NAS message

In addition, in the above implementation manner, the NAS message may be at least one of the following:

PDU session establishment request (PDU session Establishment Request);

PDU Session Modification Request (PDU Session Modification Request).

The above Analytics Container may include at least one of the following:

Analysis ID/Event ID (Analytics ID/Event ID), where the Analytics ID is used to identify which type of analysis in the NWDAF the UE wants to subscribe to or obtain. For example, when Analytics ID = "Service Experience", it means that what you want to subscribe is the analysis result of service experience in NWDAF.

Target of Analytics Reporting (Target of Analytics Reporting), where the analysis results are oriented to the group, here mainly refers to the terminal. For example, a single terminal uses SUPI or GPSI; it can also be a group of UEs or any UE. The UE indicates here that this value is the analysis result of which UE or which group of UEs the NWDAF is expected to provide.

Event or analysis filter information (Event filter information/Analytics filter information), this parameter is used as a filter parameter to obtain detailed content under the Analytics ID/Event ID. For example, when the Analytics ID = "Service Experience", the UE wants to subscribe to the service experience; but this service experience includes many APPs. Therefore, the UE can set that the event filter information (Event filter) includes the application program identification (APP ID), APP ID=XXX video (Video), so that the UE subscribes to the service experience of XXX video.

Terminal identification information (UE information), this information is to tell NWDAF which UE has subscribed to the above-mentioned analysis and analysis. UE information includes: SUPI, GPSI, UE IP address, etc.

In some implementation manners, other parameters may also be included, which are not limited thereto.

Step 2: After receiving the NAS message from the UE, the SMF finds that there is an Analytics Container, or that there is information about the analysis results of the NWDAF that the UE wishes to subscribe to. Then the SMF knows that the UE wants the SMF to help him subscribe to the NWDAF analysis content.

After receiving the NAS message sent by a certain UE, the SMF opens the Analytics Container, or directly obtains the analysis result information of the NWDAF that the UE wants to subscribe to in the NAS message, and then obtains the parameters in it, and decides to initiate an analysis of the NWDAF in a certain NWDAF. The analytics subscription request:

Approach 1: SMF initiates a subscription or request to NWDAF: as in step 2a in Figure 5:

Analytics Subscription (Nnwdaf_AnalyticsSubscription);

Analytics Information Request (Nnwdaf_AnalyticsInfo_Request).

In the above two signalings for subscribing or directly requesting analysis results, parameters may include at least one of the following:

Analysis ID, event ID, analysis report target, analysis target period (Analytics target period), terminal identification information.

Further, at least one of the following may also be included:

Analytics Filter Information, preferred level of accuracy of the analytics, accuracy level per analytics subset, time when analytics information is needed ), maximum number of objects requested (max)), preferred order of results, maximum number of SUPIs requested (SUPImax), analysis metadata request ( Analytics Metadata Request), Dataset Statistical Properties, Output strategy and Data time window.

Among them, the SMF can directly obtain the parameters in the above two signalings from the Analytics Container in the NAS message sent by the UE.

Approach 2: Through DCCF, for example: sending through a data management subscription request (Ndccf_DataManagement_Subscribe).

Wherein, the data management subscription request may include at least one of the following:

Service operation (Nnwdaf service operation), analysis specification (Analytics Specification), format instruction (Formatting Instructions,), processing instruction (Processing Instructions), NWDAF (or NWDAF set) ID (NWDAF (or NWDAF-Set) ID), analysis data Analytics Data Repository Function (ADRF) information.

Among them, the above analysis specification may include at least one of the following:

Analysis ID, Event ID, Analysis Report Target, Event or Analysis Filter Information.

In this way, when DCCF is used for analysis subscription, the parameters in the analysis specification are provided by the analysis container in the UE NAS message.

It should be noted that in the above two paths, in addition to taking out the parameters in the analysis container of the NAS message sent by the terminal as an analysis subscription sent to NWDAF or DCCF, additional terminal identification information can be added to indicate which UE subscribes to this set of analytics.

Step 3. The DCCF determines the specific analysis function network element, that is, it can specifically decide whether it is NWDAF or Messaging Framework Adapter Function (MFAF).

In this step, the NWDAF that serves the UE and can provide the analysis result to the UE may be determined according to UE location information, UE subscription information, and the like.

Step 4. The DCCF determines whether the analysis result has been collected.

Step 5, DCCF may request MFAF to help send the analysis result of NWDAF. existing process. The DCCF sends a data management configuration message (Nmfaf_DataManagement_Configure) to the MFAF.

Step 6. DCCF sends an analysis subscription request to NWDAF.

Step 7, NWDAF sends a notification message.

This step may include step 7a or step 7b, where 7a is sending a notification message to the DCCF, and 7b is sending a notification message to the MFAF.

However, DCCF and MFAF send the analysis results to SMF after receiving the analysis results from NWDAF.

The analysis result is included in the notification message above.

Step 8: NWDAF can send the result of the requested analysis subscription to SMF;

Alternatively, NWDAF first sends the analysis results to DCCF or MFAF, and then DCCF or MFAF notifies SMF to send the analysis results to SMF.

Step 8a sends the analysis subscription notification (Nnwdaf_AnalyticsSubscription_Notify);

Step 8b: What is sent is a data management notification (Ndccf_DataManagement_Notify).

Step 9: The SMF sends the analysis subscription notification or analysis result sent by the NWDAF to the UE through the NAS message. It corresponds to the subscription request sent by the UE in step 1.

Wherein, the embodiment of the NAS message may include at least one of the following:

PDU session establishment acceptance message (PDU session Establishment Accept);

PDU Session Modification Command/Accept message (PDU Session Modification Command/Accept);

Registration Accept.

Step 9. The SMF sends a NAS message to the UE, and the NAS message includes the analysis result.

Step 10 is an alternative to step 9, that is, the SMF may not be sent through NAS messages. Instead, select a user plane, use the PDU session (PDU session), and send the analysis results to the UE. The PDU session is a PDU session currently being used by the UE or already established.

In this embodiment, if the NWDAF is directly requested to feed back the analysis result, the execution steps are: step 1, 2a, 8a, 9 or 10+11.

In this embodiment, if the DCCF agent is required to forward the NWDAF feedback analysis result, the execution steps are: step 1, 2, 3, 4, 6, 7a, 8b, 9 or 10+11.

In this embodiment, if the DCCF+MFAF agent is required to forward the NWDAF feedback analysis result, the execution steps are:

Steps

1, 2, 3, 4, 5, 6, 7b, 8a or 8b, 9 or 10+11.

Embodiment two:

In this embodiment, the analysis result of subscribing to NWDAF by AMF instead of UE, as shown in Figure 6, includes the following steps:

Step 1: UE sends a registration request to AMF. The UE can also send a registration request to the AMF via the RAN base station. The registration request carries an analytics container (Analytics Container), and this Container includes information about the analysis results of the NWDAF that the UE wishes to subscribe to. It is also possible that the registration request directly carries the analysis result information of the NWDAF that the UE wishes to subscribe to.

In the above-mentioned Analytics Container (same as Embodiment 1), or in the registration request, at least one of the following items may be included:

Event or analysis filter information (Event filter information/Analytics filter information), this parameter is used as a filter parameter to obtain detailed content under the Analytics ID/Event ID. For example, when the Analytics ID = "Service Experience", the UE wants to subscribe to the service experience; but this service experience includes many APPs. Therefore, the UE can set that the Event filter includes APP ID, APP ID=XXX Video, so that the UE subscribes to the service experience of XXX Video.

Step 2: After receiving the registration request message from the UE, the AMF finds that there is an Analytics Container, or the AMF finds that there is information about the analysis results of the NWDAF that the UE wishes to subscribe to in the registration request. Then AMF knows that UE wants SMF to help him subscribe to NWDAF analysis content.

After receiving a registration request message from a certain UE, the AMF opens the Analytics Container, obtains the parameters in it, or directly obtains the parameters in the registration request, and decides to initiate a request for an analysis subscription in a certain NWDAF:

Approach 1: AMF initiates a subscription or request to NWDAF: as in step 2a in Figure 6:

Analytics Subscription (Nnwdaf_AnalyticsSubscription);

Analytics Information Request (Nnwdaf_AnalyticsInfo_Request).

Further, at least one of the following may also be included:

Approach 2: Through DCCF, for example: sending through a data management subscription request (Ndccf_DataManagement_Subscribe). Corresponds to step 2.

Step 3. The DCCF decides the network element, which may specifically be the NWDAF or the Messaging Framework Adapter Function (MFAF).

In this step, the NWDAF that serves the UE and can provide the analysis result to the UE may be determined according to the location information of the UE.

Step 4. The DCCF determines whether the analysis result has been collected.

Step 5, DCCF may request MFAF to help send the analysis result of NWDAF. existing process. DCCF sends a data management configuration message (Nmfaf_DataManagement_Configure) to MFAF

Step 6. DCCF sends an analysis subscription request to NWDAF.

Step 7, NWDAF sends a notification message.

The analysis result is included in the notification message above.

Step 8: NWDAF can send the result of the requested analysis subscription to AMF;

Alternatively, NWDAF first sends the analysis results to DCCF and MFAF, and then DCCF and MFAF notify AMF to send the analysis results to AMF.

Step 9: The AMF sends the analysis result of the NWDAF to the UE through the Registration Accept message.

In this embodiment, if the NWDAF is directly requested to feed back the analysis results, the execution steps are: steps 1, 2a, 8a, 9.

In this embodiment, if the DCCF agent is required to forward the NWDAF feedback analysis result, the execution steps are: steps 1, 2, 3, 4, 6, 7a, 8b, 9.
