6.2.10.6 AIoT UE reader subscription Data Update Notification to AMF

The procedure of Subscriber Data Update Notification to AMF is performed as defined in clause 4.5.1 of TS 23.502 [4] with the following additions for AIoT UE Reader:

• The Nudm_SDM_Notification service operation sent from UDM to AMF may contain the updated UE subscription data, including the information indicating whether the UE is allowed to operate as an AIoT UE Reader.
• The AMF updates the UE context with the updated UE subscription data and determines whether there is a change on the UE authorization to operate as an AIoT UE reader. If there is a change (e.g. the UE reader authorization is revoked), AMF informs the serving NG-RAN accordingly that the UE reader is not authorized.
