[{"name":"S2-2400044","title":"LS from CT WG3: LS on Issues related to user consent for retrieving data stored in the ADRF\/NWDAF","source":"CT WG3","contact":"Xuefei Zhang","contact-id":92937,"tdoctype":"LS in","for":"Action","abstract":"CT WG3 is discussing the scope of user consent and the impact of its change on retrieving the data subject to user consent stored in the ADRF or historical data in the NWDAF. The main issue that was identified is that currently no user consent check is specified when retrieving data subject to user consent from the ADRF\/NWDAF if the user consent for certain purpose has not been checked by the NF service consumer which stores the data and the user consent checking is required by local policy or regulation. This can lead to potentially problematic situations such as the following scenario: EXAMPLE: NWDAF1 checks that user consent is granted for the purpose of 'Analytics', so it collects and stores the data into the ADRF. NWDAF2 later retrieves this data from the ADRF and (since there is no user consent check for the interaction with the ADRF) uses it also for any other purposes, e.g. for ML Model training, although the user consent did not exist for that purpose when the data was collected and stored in the ADRF by NWDAF1, which means the NWDAF2 with unchecked purpose can bypass the restriction of the user consent. CT WG3 would like to ask SA WG3 (for the security issues related to all questions) and SA WG2 (for the issues that need to be determined based on and\/or specified in 3GPP TS 23.288 clause 6.2.9 and other user consent related clauses): Question 1: Whether all the NF service consumers need to check user consent to be granted for all its usage purposes before retrieving data from the ADRF\/NWDAF? Question 2: If the answer to question 1 is yes, how to handle the user consent checking when multiple consumers retrieve the same data from the ADRF\/NWDAF for the same purpose or for different purposes?. Action: CT WG3 kindly asks SA WG3 and SA WG2 to answer above questions and amend the specifications accordingly.","secretary_remarks":"Responses drafted in S2-2400280, S2-2400988.

CT WG3 would like to remind that TS 23.288 clause 5A.1 states that the DCCF 'prevents data sources from having to handle multiple subscriptions for the same data', TS 23.288 clause 5A.2 also specifies that 'If parameters in a request for data from a Data Consumer match those in a prior request or in a data collection profile registration, the DCCF may determine that the requested data is already being collected from a Data Source', that is DCCF may determine to not create a new subscription request for the same data collection from the same Data Source for different Data Consumer. CT WG3 would like to ask SA WG3 and CT WG4: For the new source Data Consumer(s) requesting for the same data collection from the same Data Source, for which the DCCF may determine to not create a new subscription to the Data Source in order to optimize overall signaling which is aligned with DCCF functionality in TS 23.288 clause 5A.1, Question 1: Whether and how can the Data Source get and\/or authorize the CCA of the new Data Consumer(s) to retrieve the same data without requiring multiple subscriptions from DCCF?","secretary_remarks":"Noted","agenda_item_sort_order":44,"ainumber":"8.1","ainame":"Enablers for Network Automation for 5G - Phase 2 (eNA_Ph2)","tdoc_agenda_sort_order":10570,"status":"noted","reservation_date":"2023-12-19 12:45:41","uploaded":"2023-12-20 16:45:42","revisionof":"","revisedto":"","release":"Rel-17","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG3, CT WG4","Cc":"SA WG2","lsoriginalls":"C3-235594","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_160AHE_Electronic_2024-01\/Docs\/S2-2400045.zip","group":"S2","meeting":"S2-160-Ad Hoc-e","year":2024,"uicc_affected":"","me_affected":"","ran_affected":"","cn_affected":"","clauses_affected":"","crsinpack":null,"crsinpacknumber":0},
