Final Unit Indication Support
The SMF supports Final Unit Indication (FUI) in the Charging Data Initial/Update Response from CHF as per 3GPP TS 32.291, section 6.1.6.2.1.12.
On receiving FUA, the SMF installs new FAR and associates it's FAR-ID in the URR, in the FAR ID Quota Action IE. If a FAR with same parameters exists, the SMF uses it's FAR-ID in the Create/Update URR. The UPF initiates appropriate actions set in FAR after quota exhaustion.
Currently, the SMF only supports Terminate and Redirect FU actions.
