Abstract

A signaling provider network which receives and transmits at least a subset of all signaling information associated with a particular call or communication service, allows the received/transmitted signaling information to be processed independently of the originating or terminating communication carrier network which originates and/or completes the call, or provides the communication service.

Claims

1. A method of delivering a communication service comprising the steps of:

receiving, in a first communications network, signaling information from a signaling device which is coupled to a communications device that generated said signaling information to request a communication service, said signaling information being received in said first communications network via a first facility after having been modulated by said signaling device and then demodulated prior to receipt by said first communications network; and

processing the signaling information in said first communications network to generate routing information that is forwarded via said signaling device to a second communications network over a communication path which includes a second facility that is physically distinct from said first facility.

2. The method of claim 1 wherein said processing step includes the steps of:

comparing rates charged by different carriers for said communication service;

selecting the carrier charging the lowest rate;

identifying a carrier identification code for said selected carrier; and

generating said routing information indicating that said communication service is to be delivered over said communication path which includes said second facility and transmission facilities of said second communications network which belongs to said selected carrier.

3. The method of claim 1 wherein said communication service is a telephone call and wherein said processing step includes the steps of:

retrieving in said first network a prestored profile associated with a telephone number of a caller who initiated said call; and

determining a treatment for said call based on said profile, wherein information indicative of said treatment is included in said routing information.

4. A system for delivering a communication service comprising:

a signaling device;

a first communications network which receives, from said signaling device, signaling information generated by a communication device that is coupled to said signaling device and that requested a communication service, said signaling information being received by said first communications network via a first facility after having been modulated by said signaling device and then demodulated prior to receipt by said first communications network; and

a computer system in said first communications network which processes said signaling information to generate routing information that is forwarded via said signaling device to a second communications network over a communication path which includes a second facility that is physically distinct from the first facility.

5. The system of claim 4 wherein said computer system a) compares rates charged by different carriers for said communication service, b) selects the carrier charging the lowest rate, c) identifies a carrier identification code for said selected carrier, and d) generates said routing information to indicate to said signaling device that said communication service is to be delivered via said communication path which includes said second facility and transmission facilities of said second communications network which belongs to said selected carrier.

6. The system of claim 4 wherein said communication, service is a telephone call and wherein said computer system retrieves a prestored profile associated with a telephone number of a caller who initiated said call, and determines a treatment for said call based on said profile.

7. The system of claim 6 wherein said treatment includes blocking said call when said call is directed to a destination preselected as being unreachable.

8. A method of delivering a communication service in response to a communication service request from a communications device coupled to a signaling device, the method comprising the steps of:

sending from the signaling device to a first network a first set of signaling information associated with a communication service, the first set of signaling information being received by the first network via a first facility after having been modulated by the signaling device and then demodulated prior to receipt by the first network; and

in response to receipt of the first set of signaling information by the first network, transmitting from the first network to the signaling device a second set of signaling information which is forwarded via the signaling device to a second network for delivery of the communication service, the second set of signaling information being forwarded over a communication path which includes a second facility that is physically distinct from the first facility.

9. The method of claim 8 wherein the second set of signaling information includes a carrier identification code.

10. The method of claim 8 further comprising the steps of:

processing the first set of signaling information in the first network to determine a carrier identification code that is to be included in the second set of signaling information, and that is indicative of a route associated with the communication path and the second network; and

in response to receipt of the second set of signaling information by the signaling device, establishing a connection for delivery of the communication service via the route.

11. A system for delivering a communication service in response to a communication service request from a communications device comprising:

a first network;

a signaling device which is coupled to the communications device and which sends to the first network a first set of signaling information generated by the communications device to request a communication service, the first set of signaling information being received by the first network via a first facility after having been modulated by the signaling device and then demodulated prior to receipt by the first network; and

a processor in the first network which generates a second set of signaling information in response to receiving the first set of signaling information, and which transmits to the signaling device the second set of signaling information which is forwarded via the signaling device to a second network for delivery of the communication service, the second set of signaling information being forwarded over a communication path which includes a second facility that is physically distinct from the first facility.

12. The system of claim 11 wherein the second set of signaling information includes a carrier identification code.

13. The system of claim 11 wherein the processor determines a carrier identification code that is to be included in the second set of signaling information, and that is indicative of a route associated with the communication path and the second network, and wherein the signaling device, in response to receiving the second set of signaling information, establishes a connection for delivery of the communication service via the route.
