It has been identified the need for coordination with SA WG5 in order to define the interactions between NWDAF (Network Data Analytics Function) and OAM e.g. - OAM can be a potential consumer of data analytics generated by NWDAF but it is up to SA WG5 to determine whether (and if yes which) Data Analytics output could be beneficial for OAM purposes. - Conversely NWDAF could benefit from OAM information produced by management services. In addition, SA WG2 discussed the relationship with RAN WG3-led Rel-16 Study on RAN-centric Data Collection and Utilization for NR (RP-181456) and concluded that SA WG2 (in FS_eNA) will not address data collection from NG RAN, as TSG RAN groups are responsible of such aspects.","secretary_remarks":"Noted","agenda_item_sort_order":136,"ainumber":"17B.3","ainame":"(FS_eNA) - Study of enablers for Network Automation for 5G","tdoc_agenda_sort_order":12010,"status":"noted","reservation_date":"2018-08-08 12:23:05","uploaded":"2018-08-08 12:27:57","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"FS_eNA"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"SA WG5, RAN WG3","Cc":"TSG SA, TSG RAN","lsoriginalls":"S2-187617","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_81\/Docs\/SP-180633.zip","group":"SP","meeting":"SP-81","year":2018,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

With regard to SA WG2 question on OAM information, SA WG5 specifies collection of management data (e.g. alarms, performance measurements, trace records, MDT data etc.) from 3GPP networks including Core and RAN with the cooperation with other SA groups and RAN groups. SA WG5 also addresses management automation topics including management data analytics as a progression and enhancement of the LTE SON management features. Further development of SON concept into 5G is foreseen. SA WG5 specified the 5G management data analytics service (MDAS) in Release 15. Regarding the coordination between SA WG2 and SA WG5 on usage of NWDAF produced data, SA WG5 would like to know the details of the 'data analytics generated by NWDAF' in order to better assess the usefulness of these data for OAM use cases.

Network Data Analytics (NWDA) is introduced in the 5G phase1 to automatically provide slice specific network data analytics to the network. In Rel15, NWDAF only notifies or publishes slice specific network status analytic information to the PCF(s) that are subscribed to it. However, other network functions may also benefit from NWDAF reporting.  In order to improve the NWDAF related work initiated in Rel15, it looks beneficial to further investigate solutions for supporting network automation deployment with information exposure across technical domains for context mining. The work will study the necessary data to expose to NWDAF and the necessary NWDAF outputs (i.e. statistics \/ prediction) in order to e.g. support (non-exhaustive list):  - Customized mobility management per UE e.g. paging enhancements and mobility pattern - 5G QoS enhanc","secretary_remarks":"Approved","agenda_item_sort_order":136,"ainumber":"17B.3","ainame":"(FS_eNA) - Study of enablers for Network Automation for 5G","tdoc_agenda_sort_order":12030,"status":"approved","reservation_date":"2018-09-03 05:58:40","uploaded":"2018-09-03 08:27:54","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"FS_eNA"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/TSG_SA\/TSGS_81\/Docs\/SP-180792.zip","group":"SP","meeting":"SP-81","year":2018,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
