This appendix provides reference information for the Oracle Communications Offline Mediation Controller out of the box mapping for IMS CDF/CGF ECE cartridge.
The following tables display the mapping performed by the AVP Mapper EP, as it converts diameter types to 32.298 ASN.1 format.
The incomplete-CDR-Indication ASN.1 field is only outputted in the following cases:
when the Stop record is received and records are missing
or when the AP has not received a record for a given session within the configured Flush Time
The value for the causeForRecordClosing ASN.1 field is set according to the scenarios in Table A-1:
Table A-1 causeForRecordClosing Values
| Scenario | Field Value |
|---|---|
|
Success case |
serviceDeliveryEndSuccessfully |
|
Error case 1 - AP Flush Time expires |
timeLimit |
|
Error case 2 - Stop or Event record received with a positive value for the Cause-Code |
unSuccessfulServiceDelivery |
|
Partial CDR generation |
managementIntervention |
Assign - the value from each record received for a given session is used
Assign last - the value from the last record received for a given session is used
Assign first - the value from the first record received for a given session is used
Append - the values from all records received for a given session are added to a list
Table A-2 lists the value definitions for AVP Mapper EP Mapping.
