Abstract

A network data collection method from application function device for network data analytic function is disclosed. The network data collection method includes transmitting a Naf_EventExposure_Subscribe message for a subscription of an event into an application function (AF) device; and receiving a Naf_EventExposure_Notify message from the AF device when the NWDAF subscribes the event.

First claim

What is claimed is:

1 . A network data collecting method performed by a network exposure function (NEF) device, comprising:
transmitting a Nnrf_NFManagement_NFUpdate_request message for update registration information into a network repository function (NRF) device; receiving a Nnrf_NFManagement_NFUpdate_response message from the NRF device; receiving a Nnef_EventExposure_Subscribe message from a network data analytic function (NWDAF) device; transmitting a Naf_EventExposure_Subscribe message into an application function (AF) device; receiving a Naf_EventExposure_Notify message from the AF device; transmitting a Nnef_EventExposure_Notify message into the NWDAF device, wherein the Naf_EventExposure_Subscribe message comprise: (i) an input including a Target of Event Reporting, external UE ID, External Group Identifier, or indication that any UE is targeted, an Event ID, a Notification Target Address with Notification Correlation ID), Event Reporting Information and an Expiry time, (ii) an output including an Operation execution result indication, and a Subscription Correlation ID, when the subscription is accepted.

2 . The method of claim 1 , wherein the NRF device stores NEF registration information including available data to be collected from the AF device.

3 . The method of claim 1 , wherein the Nnef_EventExposure_Subscribe message comprise:
(i) an input including an Event ID, a Target of Event Reporting, a GPSI, a External Group Identifier, Event Reporting Information, or a Notification Target Address with Notification Correlation ID, and (ii) an output including a Subscription Correlation ID, or Expiry time.

4 . The method of claim 1 , further comprising:
transmitting a Naf_EventExposure_Unsubscribe message into the AF device, wherein the Naf_EventExposure_Unsubscribe comprises: (i) an input including a Subscription Correlation ID, and (ii) an output including an Operation execution result indication.

5 . The method of claim 1 , wherein the Naf_EventExposure_Notify message comprises:
(i) an input including Notification Correlation Information, an Event ID, corresponding UE external UE ID, an External Group Identifier, an indication of any UE or time stamp.

6 . The method of claim 1 , wherein the Nnef_EventExposure_Notify message comprises:
(i) an input including an Event ID, Notification Correlation Information or time stamp, and (ii) an output including an Operation execution result indication.

7 . The method of claim 1 , wherein the AF device invokes the Naf_EventExposure_Notify message into the NEF device, when the NEF device subscribes to data in the AF device.

8 . The method of claim 1 , wherein the NEF device invokes the Nnef_EventExposure_Notify message into the NWDAF device, when the NEF device receives a notification from the AF device.

9 . The method of claim 1 , wherein the NWDAF device invokes the Nnrf_NFDiscovery_Request_request message, when the NWDAF needs to discovery an available data from the AF device and the appropriated NEF device to collect the available data.

10 . A network data collecting method performed by a network data analytic function (NWDAF) device, comprising:
transmitting a Naf_EventExposure_Subscribe message for a subscription of an event into an application function (AF) device; and receiving a Naf_EventExposure_Notify message from the AF device when the NWDAF subscribes the event, wherein the Naf_EventExposure_Subscribe message comprises: (i) an input including a Target of Event Reporting, an external UE ID, External Group Identifier, or an indication that any UE is targeted, an Event ID, a Notification Target Address with Notification Correlation ID), an Event Reporting Information and Expiry time, (ii) an output including a Operation execution result indication, and a Subscription Correlation ID, when the subscription is accepted.

11 . The method of claim 10 , wherein the Naf_EventExposure_Notify message comprises:
(i) an input including Notification Correlation Information, an Event ID, corresponding UE external UE ID, an External Group Identifier, an indication of any UE or time stamp.

12 . The method of claim 10 , further comprising:
transmitting a Naf_EventExposure_Unsubscribe message into the AF device, wherein the Naf_EventExposure_Unsubscribe comprises: (i) an input including a Subscription Correlation ID, and (ii) an output including an Operation execution result indication.
