Abstract

A system for a visited mobile telecommunications network, for sending information relating to roaming use back to a home network of the roaming user, sends telco records in near real time over a direct, P2P route, over the internet, not via a central clearing house. By sending the information more quickly, fraud detection at the home network can be improved. As this decentralized arrangement involves lower costs to the visited network, it is more likely to be installed by operators in higher risk areas, so benefits of wider coverage (“critical mass”) can be achieved. A central WebManager manages the P2P network and maintains a record of operators to verify the information sent between nodes of the P2P network, is from a recorded operator.

Claims

1. A system for a first mobile telecommunications network, for sending information relating to use of the first network by a roaming user from one of many other mobile telecommunications networks, the system including at least one processor having instructions to:

identify which of the other networks is a home network of the roaming user, and send the information to an operator of the home network, in near real time over a direct peer-to-peer (P2P) route.

2. The system of claim 1, having instructions to route the information over the public internet.

3. The system of claim 2, having instructions to route the information in a secure, encrypted form.

4. The system of claim 3, having instructions to receive information from other operators, relating to roaming by a user whose home network is the first network, the information being routed over a direct P2P route.

5. The system of claim 4, having instructions to cooperate with a central manager for verifying the validity of a sender of the information received, the central manager having a record of operators who have agreed to be roaming partners.

6. The system of claim 5, having instructions to allow operators to remotely update the record of operators who have agreed to be roaming partners.

7. The system of claim 4, having instructions to provide the received information to a fraud detection system.

8. The system of claim 7, the received information comprising one or more call detail records.

19. A method of offering a data transmission service over a network having the system of claim 1.

9. A system for a first mobile telecommunications network, for sending information relating to use of the first network by a roaming user from one of many other mobile telecommunications networks, the system including one or more processors having instructions to:

identify which of the other networks is a home network of the roaming user, and

send the information to an operator of the home network, in near real time over the public internet.

10. The system of claim 9, having instructions to route the information in a secure, encrypted form in a point-to-point manner.

11. The system of claim 9, having instructions to receive information from other operators, relating to roaming by a user whose home network is the first network, the information being routed over the public internet.

12. The system of claim 11, further having instructions to use the received information for fraud detection.

13. A method of detecting roaming fraud for use by an operator of a first mobile telecommunications network, when subscribers of the first network conduct roaming usage of one of many other mobile telecommunications networks, the method comprising:

receiving information from another of the operators, relating to the roaming usage, the information being routed over a direct P2P route, and,

using the received information to detect fraudulent usage.

14. A method of roaming usage by a subscriber of a first mobile telecommunications network, the network having a fraud detection system, the method comprising:

conducting roaming usage when visiting one of many other telecommunications networks,

causing the visited network to send information relating to the roaming usage, to the first network, for use by the fraud detection system, the information being routed over a direct, P2P route, and

receiving a bill from the operator of the first network which has been checked for fraudulent usage, and including an amount for the roaming usage.

16. A central manager for use with a P2P network used for sending information relating to roaming usage between network operators, the manager having:

a record of operators who are in the P2P network, and

an arrangement for communicating with nodes of the network, to verify the information sent between nodes of the P2P network, is from a recorded operator, using the record.

17. The central manager of claim 16, additionally being arranged to provide central management of the P2P network.

18. A method of offering a central validation service for a P2P network used for sending information relating to roaming usage between network operators, the method comprising:

maintaining a record of operators who are in the P2P network, and

communicating with nodes of the network, to verify information sent between nodes of the P2P network, using the record.
