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.
messages as 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 except custom43 dictionary. This feature is CLI-controlled.
Note that inclusion of this field in the 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 only if it is enabled at command level, i.e. using the gtpp attribute furnish-
charging-information command in GTPP Server Group Configuration mode.
charging-information command in GTPP Server Group Configuration mode.
Whenever FCI changes, a new Free-Format-Data (FFD) value is either appended to existing FFD or overwritten on the
existing FDD depending on Append-Free-Format-Data (AFFD) flag. CDR is not generated upon FCI change.

FCI is supported in main CDR as well as in LOSDV. Whenever a trigger (volume, time, RAT, etc.) happens current
available FFD at command level is added to the main body of the CDR. The same FFD at command level is added to the
main body of the next CDRs until it is not appended or overwritten by next Credit-Control-Answer message at command
level.

In the case of custom43 dictionary, the FCI implementation will be as follows:

Translation for the PS-Free-Format-Data in CDR will be conversion of hexadecimal values in ASCII format (for
