Usage Data Records (UDR)
The Usage Data Records contain accounting information related to a specific mobile subscriber. UDRs are generated
and stored on the system as records in CSV format (comma separated values). The CDR subsystem in conjunction with
the External Storage Server (ESS) are responsible for offloading of UDRs. UDRs are generated per content type. The
fields required as part of usage data records are configurable and stored in the System Configuration Task (SCT). UDRs
are generated at the end of a call, i.e. call termination, time threshold, volume threshold, and handoffs.
