The clause 6.7.4 defines how a service consumer learns from the NWDAF the expected UE behaviour parameters as defined in clause 188.8.131.52 of TS 23.502 for a group of UEs or a specific UE.
The service consumer may be an NF (e.g. AMF, AF), or the OAM.
The consumer of these analytics shall indicate in the request:
Analytics ID = "UE Mobility" or "UE Communication".
Target of Analytics Reporting: a single UE (SUPI) or a group of UEs (an Internal Group ID).
An Analytics target period, which indicates the time period over which the statistics or predictions are requested.
Analytics Filter Information optionally including:
Area of Interest (AOI);
an optional list of analytics subsets that are requested (see clause 184.108.40.206).
Optional maximum number of objects.
In a subscription, the Notification Correlation Id and the Notification Target Address are included.
The NWDAF shall notify the result of the analytics to the consumer as indicated in clause 220.127.116.11.
In order to produce "UE Mobility" analytics, the NWDAF collects UE mobility information, UE location trends and/or UE access behaviour trends, as defined in clause 18.104.22.168.
In order to produce "UE Communication" analytics, the NWDAF collects UE communication information, UE communication trends, UE session behaviour trends and/or UE access behaviour trends, as defined in clause 22.214.171.124.
5GC NF (e.g. AMF, SMF and AF) to NWDAF: Nnwdaf_AnalyticsInfo_Request (Analytics ID, Target of Analytics Reporting, Analytics Filter Information) or Nnwdaf_AnalyticsSubscription_Subscribe (Analytics ID, Target of Analytics Reporting, Analytics Filter Information).
The Analytics ID is set to "UE Mobility" or to "UE Communication", and the consumer request analytics.
If Analytics ID is set to "UE Mobility", the NWDAF collects data from OAM, AMF and/or AF as specified in clause 126.96.36.199 step 2, unless the information is already available.
If Analytics ID is set to "UE Communication", the NWDAF collects data from AMF, SMF and/or AF as specified in clause 188.8.131.52 step 2, unless the information is already available.

The NWDAF provides requested Expected UE behaviour to the NF, using either Nnwdaf_AnalyticsInfo_Request response or Nnwdaf_AnalyticsSubscription_Notify, depending on the service used in step 1.
