Communications system with fraud monitoring
First Claim
Patent Images
1. A method for monitoring activity in a communications system comprising the steps of:
- obtaining at least one first record relating to a first transport network, wherein the first transport network is a circuit-switched network;
obtaining at least one second record relating to a second transport network, wherein the second transport network is a data network;
determining that the first record and second record are both associated with a communication session;
determining at least one aspect of the communications session based upon content of both the first record and the second record; and
generating a fraud alert based on the determined aspect of the communication session.

Abstract
A fraud monitoring system is disclosed for a communications system. The fraud monitoring system analyzes records of usage activity in the system and applies fraud pattern detection algorithms to detect patterns indicative of fraud. The fraud monitoring system advantageously accommodates transaction both records resulting from control of a packet-switched network and those from a circuit-switched network gateway.

11. A method for supporting fraud monitoring, the method comprising the steps of:
-
collecting a first transaction record associated with a circuit-switched network; collecting a second transaction record associated with a packet-switched network, wherein the first transaction record and the second transaction record correspond to a common communication session transported by the circuit-switched network and the packet-switched network; generating a third transaction record from the first transaction record and the second transaction record; and generating a fraud alert based on the third transaction record associated with the common communication session. - View Dependent Claims (12, 13)

14. A system for supporting fraud monitoring, the system comprising:
-
a first receiver configured to collect a first transaction record associated with a circuit-switched network; a second receiver configured collect a second transaction record associated with a packet-switched network, wherein the first transaction record and the second transaction record correspond to a common communication session transported by the circuit-switched network and the packet-switched network; and a record converter configured to generate a third transaction record from the first transaction record and the second transaction record, wherein a fraud alert is generated based on the third transaction record associated with the common communication session. - View Dependent Claims (15, 16)
