Feature Description
The Downlink Data Notification (DDN) Call Flow Optimization feature lets you suspend the invoking of the DDN procedure for a specified period. With this feature, the network-initiated service request procedure is scheduled before the DDN is received and the UE is moved to the active state. In case of the timer expiry, if the UE ID is active, or the Modify Bearer Request is in progress, the cnSGW ignores the DDN procedure.
