摘要

A system for using a plurality of Bad Billed Number Record (BBN) to detect fraud in a telecommunications system includes a network operator service platform (220) for generating BBNs based on received call attempts; a network information concentrator (250) for temporarily storing the generated BBNs (225); and a fraud monitoring system (260) for retrieving the stored BBNs (225), filtering out unidentifiable BBNs, analyzing identifiable BBNs, and generating alarms based on the analysis.
