Feature Changes
RAN Bandwidth Optimization
When the rule is installed and active, P-GW 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

Command Changes
ran bandwidth optimize
This command is used to enable optimized calculation of [MBR, GBR] when a subscriber (voice) call is put on hold in
case of VoLTE.

During session setup, when a CCA-I is received, and if
ran bandwidth optimize
is configured for the associated
rulebase, the system will aggregate [MBR, GBR] values of only the rules which have flow-status='ENABLED'. This
information will subsequently be sent to UE.

By default, this CLI will be disabled. Any change in this configuration will not affect existing calls on the system.
Optimized bandwidth calculation will be done only for the new calls established after enabling this CLI command.
