Limitations
This feature has the following limitations in this release:
-
No support for non-3GPP specification or emergency registration SOR.
-
No support for multiple UDM data changes NotificationRequest at the time for SOR.
-
No support when the UDM sends data change notification for SMS, SOR, or RAT restriction all-together. In this scenario, the AMF ignores the SOR and the RAT restriction data changes and notifications.
-
No support when the service request is received with PDU sync request. In this scenario, the response paging request is ignored from the AMF, due to SOR UDM data changes and notifications.
-
No support when the AMF starts accepting the service with PDU sync up, and the UE context setup procedure. In this scenario, it later sends DL NAS Transport for SOR changes and notifications.
