Abstract

A cross-network call identifying function for identifying instances of international call interconnect bypass telecommunications fraud. The cross-network call identifying function access call detail records of both the terminating network and the originating network. The cross-network call identifying function identifies an outgoing international phone call from a caller within the originating network to a callee within the terminating network. The call detail records of the terminating network are querried for an incoming call with a matching callee call identifier. Time information of the outgoing call and the incoming call are compared to determine whether there is a match. If the callee call identifiers and time information match, but the incoming phone call is recorded as a local call, then the incoming call is identified as an instance of international call interconnect bypass fraud.

Claims (52)

1. A method of identifying instances of international call interconnect bypass telecommunications fraud, the method comprising:

establishing a first network connection with a first server having a first call details record (CDR) of the originating telecommunications network stored thereon;

accessing the first CDR and identifying therein an outgoing call from the caller registered in the originating telecommunications network to the callee registered in the terminating telecommunications network, the callee having a first identifier associated therewith;

establishing a second network connection with a second server having a second CDR of the terminating telecommunications network stored thereon;

accessing the second CDR and querying the second CDR for a record of an incoming call corresponding to the outgoing call based on the first identifier of the callee;

responsive to identifying, within the second CDR, the record of the incoming call corresponding to the first identifier of the callee, determining whether the incoming call is recorded within the second CDR as a local call or an international call;

responsive to determining that the incoming call is recorded in the second CDR as the local call, identifying the incoming call as an instance of the international call interconnect bypass telecommunications fraud; and

automatically transmitting a communication to a network administrator notifying the network administrator of the instance of the international call interconnect bypass fraud associated with the incoming call.

2. The method of claim 1 , wherein prior to identifying the incoming call as the instance of the international call interconnect bypass telecommunications fraud, verifying whether time information corresponding to the outgoing call matches time information corresponding to the incoming call, the time information being selected from the group consisting of a call duration, a call origination time, a call termination time, and a combination thereof.

3. The method of claim 2 , wherein the step of verifying whether the time information corresponding to the outgoing call matches the time information corresponding to the incoming call comprises:

obtaining, from the first CDR, the time information corresponding to the outgoing call;

obtaining, from the second CDR, the time information corresponding to the incoming call; and

determining whether the time information corresponding to the outgoing call matches the time information corresponding to the incoming call.

4. The method of claim 1 , wherein the cross-network call identifying routine identifies, within the plurality of the transit operators, a first transit operator that committed the international call interconnect bypass telecommunications fraud.

5. The method of claim 4 , wherein the first transit operator is identified by analyzing multiple instances of the international call interconnect bypass telecommunications fraud in which the first transit operator is one of the plurality of the transit operators involved in routing the phone call.

6. The method of claim 4 , wherein the first transit operator is excluded from the plurality of the transit operators for routing of subsequent phone calls.

7. A method of identifying instances of international call interconnect bypass telecommunications fraud committed by a first transit operator within a plurality of transit operators used to route an international phone call from a caller in an originating telecommunications network to a callee in a terminating telecommunications network, wherein the originating telecommunication network and the terminating telecommunications network serve different countries, the method comprising:

establishing a first network connection with a first server having a first call details record (CDR) of the originating telecommunications network stored thereon;

accessing the first CDR and identifying therein an outgoing call from the caller registered in the originating telecommunications network to the callee registered in the terminating telecommunications network, the callee having a first identifier associated therewith;

establishing a second network connection with a second server having a second CDR of the terminating telecommunications network stored thereon;

accessing the second CDR;

querying the second CDR for a record of an incoming call corresponding to the outgoing call based on the first identifier of the callee;

responsive to identifying, within the second CDR, the record of the incoming call corresponding to the first identifier of the callee, determining whether the incoming call is recorded within the second CDR as a local call or an international call;

responsive to determining that the incoming call is recorded in the second CDR as the local call, identifying the incoming call as an instance of the international call interconnect bypass telecommunications fraud;

identifying, within the plurality of the transit operators, the first transit operator that committed the international call interconnect bypass telecommunications fraud; and

automatically excluding the first transit operator from the plurality of the transit operators for routing of subsequent phone calls.

8. The method of claim 7 , wherein prior to identifying the incoming call as the instance of the international call interconnect bypass telecommunications fraud, verifying whether time information corresponding to the outgoing call matches time information corresponding to the incoming call, the time information being selected from the group consisting of a call duration, a call origination time, a call termination time, and a combination thereof.

9. The method of claim 8 , wherein the step of verifying whether the time information corresponding to the outgoing call matches the time information corresponding to the incoming call comprises:

obtaining, from the first CDR, the time information corresponding to the outgoing call;

obtaining, from the second CDR, the time information corresponding to the incoming call; and

determining whether the time information corresponding to the outgoing call matches the time information corresponding to the incoming call.

10. The method of claim 7 , wherein the first transit operator is identified by analyzing multiple instances of the international call interconnect bypass telecommunications fraud in which the first transit operator is one of the plurality of the transit operators involved in routing the phone call.

11. The method of claim 7 , automatically transmitting a communication to a network administrator notifying the network administrator of the instance of the international call interconnect bypass telecommunications fraud associated with the incoming call.

12. A method of using a cross-network call identifying routine for identifying instances of international call interconnect bypass telecommunications fraud committed by a first transit operator within a plurality of transit operators used to route an international phone call from a caller in an originating telecommunications network to a callee in a terminating telecommunications network, wherein the originating telecommunication network and the terminating telecommunications network serve different countries and wherein the cross-network call identifying routine is deployed within the originating telecommunications network or the terminating telecommunications network, the method comprising:

establishing a first network connection with a first server having a first call details record (CDR) of the originating telecommunications network stored thereon;

accessing the first CDR and identifying therein an outgoing call from the caller registered in the originating telecommunications network to the callee registered in the terminating telecommunications network, the callee having a first identifier associated therewith;
