Detection and prevention of unwanted calls in a telecommunications system
A method that detects unwanted calls based on information shared between a first telecommunications network provided by a first service provider and a second service provider providing a second telecommunications network including receiving, by a data-processing system, a request to provide a telecommunications service to the first telecommunications network, the request being received by the first telecommunications network from a user of the first telecommunications network through a first gateway, and wherein the request comprises a calling party identification that identified a calling party and a called party identification that identified a called party. The method further includes examining, by the data-processing system, statistics relating to requests for telecommunications services; and generating, by the data-processing system, a first signal when the called party identification in the request appears in the statistics in excess of a predetermined first number of instances within a predetermined first time interval.

10. The method according to claim 9 , wherein the called party identification comprises digits that define the called party identification, the digits being a proper subset of digits that define a B-Number of the called party.
11. The method according to claim 9 , wherein the calling party identification comprises digits that define the calling party identification, the digits being a proper subset of digits that define an A-Number of the calling party.
12. The method according to claim 9 , further comprising denying the telecommunications service to the user of the first telecommunications network, based on the first signal being generated.
13. The method according to claim 9 , wherein the predetermined first number of instances is based on a characteristic of the first telecommunications network.
14. The method according to claim 9 , wherein the predetermined first number of instances is based on a characteristic of a third telecommunications network that corresponds to the called party identification.
15. A server computer that detects unwanted calls based on information shared between a first telecommunications network provided by a first service provider and a second service provider providing a second telecommunications network, the server computer comprising:
