Abstract

The phone number used by a caller accessing a telecommunication service is derived. For example, this phone number may be used to look up in a first database the name of the user registered with the service, and in a second database the name of the subscriber assigned the phone number. If the two names correspond, the caller is provided with the telecommunication service. Otherwise, a fraud has been detected and various consequences may be visited upon the caller or the user. Some of these consequences include denying use of the service, charging the caller extra for use of the service, etc.

Claims

1. A method for use by a provider of a telecommunication service, including information assistance, to detect fraudulent use of the telecommunication service, the method comprising:

receiving from a caller a call, which includes at least one information assistance request;

deriving, from signals associated with the call, a telephone number from which the call originates;

based on the telephone number, searching a first database for first data concerning a party registered with the service;

based on the telephone number, searching a second database for second data concerning a party to which the telephone number is assigned;

comparing the first data with the second data;

determining fraudulent use of the service if the first data does not correspond to the second data; and

providing service to the caller at a rate different from the rate given to the party registered with the service, when fraudulent use of the service is determined.

2. The method according to claim 1, wherein the first data includes the name of the party registered with the service, and the second data includes the name of the party to which the telephone number is assigned.

3. The method according to claim 1, wherein the first data includes a type of the party registered with the service, and the second data includes a type of the party to which the telephone number is assigned.

4. The method according to claim 3, wherein the type of the party registered with the service includes a business user.

5. The method according to claim 3, wherein the type of the party registered with the service includes a residential user.

6. The method according to claim 3, wherein the type of the party registered with the service includes a wireless communications user.

7. The method according to claim 3, wherein the type of the party registered with the service includes a governmental user.

8. The method according to claim 1, wherein the information assistance request comprises a request for connecting the caller to a desired destination party.

9. The method according to claim 1, wherein the information assistance request is received after the caller generates a signal to invoke information assistance.

10. The method according to claim 9, wherein the signal is generated by the caller'"'"'s pressing one or more predetermined keys on a telephonic device.

11. The method according to claim 1, wherein the telephone number is used to identify a profile containing preferences for handling the call.

12. A method for use by a provider of a telecommunication service, including information assistance, the method comprising:

defining a class of service, a party registered with the service being afforded the class of service based on at least one attribute of the party;

receiving from a caller a call, which includes at least one information assistance request;

deriving, from signals associated with the call, a telephone number from which the call originates;

obtaining from a first database the attribute which is associated with the telephone number, the attribute not including the telephone number;

based on the telephone number, searching a second database for data concerning a party to which the telephone number is assigned;

comparing the data with the attribute;

determining fraudulent use of the class of service when the data does not correspond to the attribute; and

providing service to the caller at a rate different from the rate accorded to the class of service, when fraudulent use of the service is determined.

13. The method according to claim 12, wherein the selected class of service is accorded a discount on a rate of the telecommunication service.

14. The method according to claim 12, wherein the attribute includes the name of the party registered with the service, and the data includes the name of the party to which the telephone number is assigned.

15. The method according to claim 12, wherein the attribute includes a type of the party registered with the service, and the second data includes a type of the party to which the telephone number is assigned.

16. The method according to claim 15, wherein the type of the party registered with the service includes a business user.

17. The method according to claim 15, wherein the type of the party registered with the service includes a residential user.

18. The method according to claim 15, wherein the type of the party registered with the service includes a wireless communications user.

19. The method according to claim 15, wherein the type of the party registered with the service includes a governmental user.

20. The method according to claim 12, wherein the information assistance request comprises a request for connecting the caller to a desired destination party.

21. The method according to claim 12, wherein the information assistance request is received after the caller generates a signal to invoke information assistance.

22. The method according to claim 21, wherein the signal is generated by the caller'"'"'s pressing one or more predetermined keys on a telephonic device.

23. The method according to claim 12, wherein the telephone number is used to identify a profile containing preferences for handling the call.

24. A system for use by a provider of a telecommunication service, including information assistance, to detect fraudulent use of the telecommunication service, the system comprising:

an interface for receiving from a caller a call, which includes at least one information assistance request;

a device for deriving, from signals associated with the call, a telephone number from which the call originates, first data concerning a party registered with the service being obtained from a search of a first database based on the telephone number;

at least one processor for determining fraudulent use of the service if the first data does not correspond to the second data, and

for providing service to the caller at a rate different from the rate given to the party registered with the service, when the fraudulent use of the service is determined.

25. The system according to claim 24, wherein the first data includes the name of the party registered with the service, and the second data includes the name of the party to which the telephone number is assigned.

26. The system according to claim 24, wherein the first data includes a type of the party registered with the service, and the second data includes a type of the party to which the telephone number is assigned.
