P-GW Address
These field is the serving P-GW IP address for the Control Plane. If both an IPv4 and an IPv6 address of the P-GW is
available, the P-GW shall include the IPv4 address in the CDR.

PSFurnishChargingInformation
This field contains charging information sent by the OCS in the Diameter Credit Control Credit-Control-Answer messages as
defined in 3GPP TS 32.251.
defined in 3GPP TS 32.251.
Important:
The Furnish Charging Information (FCI) feature is currently applicable to all GTPP dictionaries that
are compliant to 3GPP Rel.7 and 3GPP Rel.8 standard. Note that custom43 (rel. 8 compliant) dictionary has additional
custom handling with respect to free format data encoding and FCI change trigger for CDR generation. This feature is
CLI-controlled.
custom handling with respect to free format data encoding and FCI change trigger for CDR generation. This feature is
CLI-controlled.
Note that inclusion of this field in the CDR for any given GTPP dictionary is controlled through the CLI command
gtpp attribute furnish-charging-information
in the GTPP Server Group Configuration mode. PGW-
CDR and eG-CDR will contain FCI based on the GTPP group configuration.
For dictionaries other than custom43, whenever FCI changes, a new Free-Format-Data (FFD) value is either
appended to existing FFD or overwritten on the current FFD for online charging session depending on Append-Free-
Format-Data (AFFD) flag. CDR is not generated upon FCI change.
