Ran Bandwidth Optimization; Selective Tft Suppression For Default Bearer - Cisco ASR 5000 Series Administration Manual

▀ Enhanced Features and Functionality

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.
The RAN bandwidth 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. This operation is controlled through a CLI command "
" added in the rulebase configuration mode.

For more information on this command, see the ACS Rulebase Configuration Mode Commands chapter in the Command
Line Interface Reference.

Selective TFT Suppression for Default Bearer

With this feature, the selected TFT updates can be controlled and sent to the UE. A new CLI command "
" is introduced, which suppresses the selected TFT updates to the UE. This is provided by specific charging-action
ue
level option to identify if the appropriate TFT defined in the charging action needs to be sent to the UE or not. This CLI
is supported for both default and dedicated bearer.
One more new CLI "
operator has the flexibility to configure this per Rulebase and also configure to suppress TFT updates only. This CLI
allows sending other QoS updates to the UE and is only controlling TFT related updates. This CLI is supported only for
default bearer.
For more information on these commands, see the ACS Charging Action Configuration Mode Commands and ACS
Rulebase Configuration Mode Commands chapters in the Command Line Interface Reference.
