Release Change Reference, StarOS Release 16 ▄

CSCun18463 - Gx: CCR-U for Revalidation_timeout sent even after disabling

the trigger

Applicable Products: GGSN, HA, PDSN, P-GW

Feature Changes

No CCR-U for Revalidation_timeout When Trigger is Inactive

Previous Behavior: CCR-U is triggered for Revalidation_timeout event trigger even if the trigger is disabled.

New Behavior: Now, CCR-U will not be sent for Revalidation_timeout if the trigger is not active.

CSCun34690 - IPSG sessions cleared with REAUTH_ADD_FAILURE upon CCA-

u arrival on Gx

Applicable Products: IPSG

Feature Changes

QoS Validation based on QCI Type

Previous Behavior: IMS Authorization Service validated the guaranteed bit rate for both types of QCI i.e. non-GBR
QCI and GBR QCI.

When QoS-Information is included in CCA-I, IMSA module validated the guaranteed bit rate for both non-GBR QCI &
GBR QCI. If the validation is successful, then QoS is updated else the operation is rejected and a bad answer is sent to
PCRF. Debug log is maintained and the call is dropped.

When QoS-Information is included in CCA-U, IMSA module validated the guaranteed bit rate for both types of QCI. If
the validation is successful, then QoS should be updated else the operation is rejected and debug log is written.

New Behavior: Now, IMSA module will validate the guaranteed bit rate only for GBR QCI received from PCRF.

Whenever the IMSA module receives QoS-Information from PCRF and if it is a non-GBR QCI, then IMSA module
does not validate the guaranteed bit rate.

CSCun51012 - Bulkstat variables to be added for Switches-Tx timeout,

Switches-RAR ch

Applicable Products: GGSN, HA, IPSG, PDSN, P-GW, SAEGW

Performance Indicator Changes

IMSA Schema

The following new variables are added to support bulkstatistics for peer switches due to Tx timeout and peer switches
due to change in peer after RAR received from a different peer.
