Paging

The AMF starts a paging procedure when the SMSF sends the UE Reachability event for the MT SMS, and the UE is in the IDLE state. The AMF determines the paging profile specific to the SMS based on the configured trigger type. AMF uses the default paging profile when the paging profile is not configured.

When AMF receives the UDM notification containing the new data, and the UE is in the IDLE state, the AMF pages the UE to send the UE configuration update.
