CSCug78671, CSCui08938, CSCui08968 - support for SN-Transparent-Data on
Gx, Gy and CDRs - GGSN
Applicable Products: GGSN, IPSG
Feature Changes
SN-Transparent-Data AVP on Gx, Gy and GGSN CDRs
SN-Transparent-Data AVP carries current PDP session information. Once the session specific information such as
operator-id, GPS id, satellite-id, etc are made available to the gateway via RADIUS or PCRF interfaces, the same
session information can be carried over to other interfaces such as Gx, Gy and Gz (eGCDR) for billing and charging
purposes. Any change in SN-Transparent-Data will not be triggering an update, but the updated values will be reported
during the next CCR-Request.

This feature is currently applicable to only GGSN and IPSG products and is available only in custom46 for eGCDR and
dynamic-dictionary for Gy.
dynamic-dictionary for Gy.
Previous Behavior: Earlier, r8-gx-standard dictionary was used for this requirement.
New Behavior: Now, the Diameter dictionary “dpca-custom22” is created based out of r8-gx-standard dictionary to
support a new AVP “SN-Transparent-Data”. GGSN sends this new AVP along with ULI and Timezone in CCR
messages to PCRF.

For this requirement on Gy interface, dynamic dictionary is created based on dcca-custom8 dictionary to support the
new AVP “SN-Transparent-Data”. Similarly, for this requirement on Gz interface (for eGCDRs), GTPP dictionary
“custom46” is newly added to support the new AVP “SN-Transparent-Data”.

Customer Impact: This feature helps the operator to do subscriber specific billing. By co-relating the same subscriber
specific information across various interfaces, billing can be easily reconciled and charged to the subscriber accurately.

CSCuh24827 - Support new Interfaces for Tracing: Gy : GGSN/PGW/SAEGW
Applicable Products: GGSN, P-GW, S-GW, SAEGW
Feature Changes
Management Tracing for Gy Interface
Previous Behavior: Currently, tracing of subscriber sessions on Gy and Gz interfaces are not supported in GGSN, P-
GW and S-GW products.
GW and S-GW products.
New Behavior: The “
session trace
” CLI command has been enhanced to support Gy and Gz interfaces while
enabling management trace for GGSN, P-GW and S-GW products.
Command Changes
session trace
gy
is a new keyword in this command to enable session tracing capabilities for Gy subscribers.
