Feature Description

SMF supports auto-reclamation of under-utilized IP chunks that are allocated to various UPF nodes. By configuring the Utilization Threshold and Inactivity Threshold, SMF can trigger the auto-reclamation process periodically or on an instant basis.

The under-utilization and inactivity of IP chunks are detected based on the inactivity timer configuration. When inactivity and under-utlization are detected, SMF triggers IP chunk reclamation by clearing all the subscribers using the IP chunk. SMF also triggers route deletion to UPF.
