Usage Detail Records (UDRs)

Usage Detail Records (UDRs) contain accounting information based on usage of service by a specific mobile

subscriber. UDRs are generated based on the content-id for the subscriber, which is part of charging action. The fields

required as part of usage data records are configurable and stored in the System Configuration Task (SCT).

UDRs are generated on any trigger of time threshold, volume threshold, handoffs, and call termination. If any of the

events occur then the UDR subsystem generates UDRs for each content ID and sends to the CDR module for storage.

The UDRs are generated in Comma Separated Values (CSV) format as defined in the traffic analysis rules.
