Flow-Status AVP value.
Usage
Use this command to enable optimized calculation of [MBR, GBR] values when a subscriber (voice) call is
put on hold in case of VoLTE.
When the rule is installed and active, the system uses the GBR/MBR assigned in the rule for calculating the
GBR / MBR values towards the bearers created. When more than one rule is installed, P-GW adds the GBR /
MBR values from all the active and installed rules even if the flow of a certain rule is marked as disabled.
This current behavior is in accordance with 3GPP TS standard specification 29.212, and this might result in
RAN bandwidth wastage. To avoid this wastage, some optimization is done while calculating MBR and GBR
for GBR bearer.
This optimization feature provides the ability to configure a list of APNs, for which the optimized calculation
of MBR, GBR can be enabled. By default, this optimized calculation should be enabled only for the IMS
APN.
This feature further helps optimize the logic of aggregating MBR and GBR values, based on “Flow-Status”
AVP value received in the rule definition through RAR.

During session setup, when a CCA-I is received, and if

status='ENABLED'. This information will subsequently be sent to UE.
Important:
The last used [MBR, GBR] for GBR bearer needs to be recovered in the event of a session manager
or chassis switchover. Failure to do so can result in miscalculation of [MBR, GBR] after recovery.
