The Generic Public Subscription Identifier (GPSI) of the roaming UE.

In order to further explain any embodiments of the present disclosure, several specific examples are provided below.

The disclosed embodiment provides an information processing method to ensure that user privacy information is not leaked in the eNA roaming scenario by checking the user consent (User Consent) in the eNA (enablers for Network Automation, network automation) roaming scenario in HPLMN/VPLMN .

Among them, UDM can maintain VPLMN-specific user consent information and supervision policies, and can provide VPLMN-specific user consent to NEF.

When receiving a data collection and/or analysis collection request from V-NWDAF, NEF is able to send a request to UDM to obtain VPLMN specific user consent parameters.

Upon receipt of the response message from the UDM, NEF is able to store the VPLMN specific user consent parameters.

The NEF is able to check VPLMN specific user consent parameters and regulatory parameters to determine whether a request from the VPLMN for data collection/analysis results in the home network is acceptable.

V-NWDAF, if supervision parameters are configured/provided, can determine whether the consumer NF in the VPLMN can request data collection and/or analysis results in the home network.

As shown in Figure 6, the information processing method may include the following steps:

0: UDM stores the user consent information of the VPLMN's roaming UE as well as operator policies and/or regulatory policies. The user consent information of the roaming UE of the VPLMN is associated with the identity of the roaming UE (for example, SUPI), and is stored in the UDM as subscription data. Among them, regulatory policies are country or region specific and can be used in roaming scenarios.

1: The consumer NF in the VPLMN sends the subscriber's data collection and/or analysis request message to the V-NWDAF. The message includes the objectives of the analysis report. A specific UE, a group of UEs, or any UE can be set as the target of the analysis report. If a group of UEs or any UE is used as the target of the analysis report, the message also includes indication information indicating the ID of the roaming UE and the ID of the PLMN of the VPLMN.

2: The V-NWDAF determines to collect data and/or analysis from the NF and/or NWDAF in the HPLMN based on the request message received from the consumer NF.

3: If the operator policy and/or regulatory policy configured or provided for V-NWDAF indicates that V-NWDAF is allowed to request collection of data or analysis, V-NWDAF sends to H-NF(s) and/or H-NWDAF via NEF Data collection and/or analysis requests from contracted users.

4: If the VPLMN-specific user consent parameters are not stored in NEF, NEF sends a Nudm_SDM_GetRequest message to UDM to check the user consent information. If NEF has already obtained VPLMN-specific user consent parameters, steps 4 and 5 can be skipped.

5: UDM retrieves user consent parameters and sends Nudm_SDM_Get Response message to NEF. The message includes user consent parameters.

6: NEF receives the response message from UDM and stores VPLMN-specific user consent parameters. Based on operator policy, regulatory policy, the VPLMN's roaming agreement and the VPLMN-specific user consent, the NEF determines whether data collection and/or analysis requests from the VPLMN can be provided to the consumer NF in the HPLMN. If the user consent parameter indicates that V-NWDAF is allowed to request data collection at H-NF(s) and/or analysis at H-NWDAF, NEF will send the data collection and/or analysis to H-NF(s) and/or H-NWDAF.

7: H-NF(s) and/or H-NWDAF provide data collection and/or analysis results to V-NWDAF through NEF.

8: V-NWDAF generates analysis results of consumer NF requests.

9: V-NWDAF provides analysis results to consumer NF.

In some embodiments, the UDM maintains the following parameters for VPLMN specific user consent:

UE ID: used to identify the subscriber, which can be SUPI.

Data processor ID: used to identify the service provider that provides data analysis services for the UE, which can be a PLMN ID. In roaming scenarios, the VPLMN ID needs to be maintained together with the HPLMN ID.

The purpose of data processing: Indicates a data analysis service, which can be a service operation name (such as Nnwdaf_AnalyticsSubscription_Subscribe), with a specific analysis ID input.

User consent result: whether the data processor agrees to process the data according to the purpose of data processing. In a roaming scenario, if the user agrees to disclose data or analysis to HPLMN or VPLMN, the user consent results can be classified as:

-Processed only in HPLMN: Data collected in the home network can only be processed in HPLMN, i.e. the collected data and/or analysis results can only be provided to the Consumer NF in HPLMN.

-Processed only in VPLMN: Data collected in the visited network can only be processed in VPLMN, i.e. the collected data and/or analysis results can only be provided to Consumer NFs in VPLMN.

-Provided to VPLMN and HPLMN: The analysis results in the visited network or home network can be provided to HPLMN or VPLMN according to operator policy and/or regulatory policy. But the data collected in the visited network or home network cannot be provided to HPLMN or VPLMN.

- Processing in VPLMN and HPLMN: Depending on operator policy and/or regulatory policy, data collected in the visited network or home network can be processed in VPLMN or HPLMN, i.e., both the data collected and the analysis results can be processed in VPLMN and HPLMN transmitted between.

These parameters may be included in a specific subscriber's user consent for specific web analytics services provided by a specific service provider.
