Method and system for providing communication analysis of user equipment based on network data analysis

A method for providing UE (User Equipment) communication analysis, comprising:

• receiving, by an NWDAF (Network Data Analytic Function) device, an Nnwdaf_AnalyticsSubscription_Subscribe service operation from an NF (Network Function) device;
• invoking, by the NWDAF device, an Nsmf_EventExposure_Subscribe service operation to an SMF (Session Management Function) device;
• invoking, by the NWDAF device, an Namf_EventExposure_Subscribe service operation to an AMF (Access Management Function) device;
• deriving, by the NWDAF device, UE communication analytics;
• and
• providing the UE communication analytics to the NF device,
• wherein the UE communication analytics includes at least one of a UE group ID or a UE ID, UE communications, a Periodic communication indicator, a Periodic time, a Start time, a Duration time, a Traffic characterization, a Traffic volume, a Confidence and a Ratio,
• wherein the UE group ID or UE ID is information for identifying the UE or a group of a plurality of UEs,
• wherein the Ratio is a proportion of UEs in the group for a given communication at a given time and duration, and
• wherein the Confidence is for the UE communication analytics and a value of the Confidence depends on a level expressed by a parameter “time when analytics information is needed”.
