Abstract
A method and system for providing service experience analysis based on network data analysis is disclosed. According to the method, the NWDAF device can provide the service experience statistics or service experience prediction for an application or a network slice.
Claims20
A method for providing service experience analysis comprising:
- receiving, by a NWDAF (network data analytics function) device, a Nnwdaf_AnalyticsInfo_Request service operation or a Nnwdaf_AnalyticsSubscription_Subscribe service operation from a first NF (network function) device, wherein the Nnwdaf_AnalyticsInfo_Request service operation or the Nnwdaf_AnalyticsSubscription_Subscribe service operation includes analytics ID corresponding to service experience;
- invoking, by the NWDAF device, a Naf_EventExposure_Subscribe service operation to an AF (application function) device, wherein the Naf_EventExposure_Subscribe service operation includes event ID and the event ID corresponds to service data;
- invoking, by the NWDAF device, a Nnf_EventExposure_Subscribe service operation to a second NF device as a network data provider, wherein the Nnf_EventExposure_Subscribe service operation includes the event ID;
- deriving, by the NWDAF device, a request analytics for an application;
- invoking a Nnwdaf_AnalyticsInfo_Request Response service operation or a Nnwdaf_AnalyticsSubscription_Notify service operation to the first NF device, wherein the Nnwdaf_AnalyticsInfo_Request Response service operation and the Nnwdaf_AnalyticsSubscription_Notify service operation includes an estimated service experience.

An apparatus for providing service experience analysis comprising:
- one or more processor of a NWDAF (network data analytics function) device configured to:
- receive a Nnwdaf_AnalyticsInfo_Request service operation or a Nnwdaf_AnalyticsSubscription_Subscribe service operation from a first NF (network function) device, wherein the Nnwdaf_AnalyticsInfo_Request service operation or the Nnwdaf_AnalyticsSubscription_Subscribe service operation includes analytics ID corresponding to service experience;
- invoke a Naf_EventExposure_Subscribe service operation to an AF (application function) device, wherein the Naf_EventExposure_Subscribe service operation includes event ID and the event ID corresponds to service data;
- invoke a Nnf_EventExposure_Subscribe service operation to a second NF device as a network data provider, wherein the Nnf_EventExposure_Subscribe service operation includes event ID;
- derive a request analytics for an application;
- invoke a Nnwdaf_AnalyticsInfo_Request Response service operation or a Nnwdaf_AnalyticsSubscription_Notify service operation to the first NF device, wherein the Nnwdaf_AnalyticsInfo_Request Response service operation or the Nnwdaf_AnalyticsSubscription_Notify service operation includes an estimated service experience,
- wherein the processor is a hardware processor.
