Abstract

A method of routing calls in a communication system. A call is received from an originating network in the communication system. The identity of the originating network is determined, and the call is routed in the communication system based on the identity of the originating network.

Claims

1. A service control point that routes calls, the service control point comprising:

a switch controller that is configured to determine an identity of a communication network from which a call originated, and that is configured to route the call through at least one switch toward a destination communication device based on the identity of the originating communication network.

3. The service control point of claim 1, wherein the switch controller is configured to route the call through the at least one switch toward the destination communication device in response to an originating point code in a SS7 call query.

4. The service control point of claim 3, wherein the switch controller is configured to route the call in response to the originating point code and in response to a called party address in the SS7 call query.

5. The service control point of claim 1, wherein the switch controller is configured to identify a called number to which the call is directed, and is configured to route the call through the at least one switch in response to the identity of the originating communication network and in response to the called number.

6. The service control point of claim 5, wherein the switch controller is configured to route the call through the at least one switch toward the destination communication device in response to whether the called number comprises a toll-free long-distance number and in response to whether the identity of the originating communication network is associated with a predetermined telecommunications carrier.

7. The service control point of claim 6, wherein the switch controller is configured to route the call through the at least one switch in response to whether the called number comprises a toll-free long-distance number that is associated with the predetermined telecommunications carrier.

8. The service control point of claim 5, wherein the switch controller is configured to route the call through the at least one switch toward the destination communication device in response to a called party address in a SS7 call query.

9. The service control point of claim 5, wherein the switch controller is configured to determine an association between the called number to which the call is directed and a plurality of call numbers that are associated with a predetermined telecommunications carrier in response to the call, and is configured to route the call through the at least one switch toward the destination communication device in response to the determined association.

10. The service control point of claim 1, further comprising a database associating network identifications with phone numbers, alternate carrier identification codes, and alternate phone numbers, and wherein the switch controller is configured to identify a called number to which the call is directed, and is configured to identify an alternate carrier identification code and an alternate phone number in response to the identity of the originating network and a called number to which the call is directed, and is configured to route the call through the at least one switch toward the destination communication device in response to the identified alternate carrier identification code and the identified alternate phone number.

11. The service control point of claim 1, wherein the switch controller is configured to route the call to a first destination when the identify of the originating communication network corresponds to a predetermined telecommunications carrier, and to route the call to a second destination when the identity of the originating communication network does not correspond to the predetermined telecommunications carrier.

2. (canceled)

12. A method of routing calls, the method comprising:

determining an identity of an originating communication network from which a call has been received; and

routing the call through at least one switch toward a destination communication device based on the identity of the originating communication network.

13. The method of claim 12, wherein the call is routed through the at least one switch toward the destination communication device in response to an originating point code in a SS7 call query.

14. The method of claim 13, wherein the call is routed through the at least one switch toward the destination communication device in response to the originating point code and in response to a called party address in the SS7 call query.

15. The method of claim 12, further comprising:

identifying a called number to which the call is directed, and wherein the call is routed through the at least one switch toward the destination communication device in response to the identity of the originating communication network and in response to the called number.

16. The method of claim 15, further comprising:

identifying a called number to which the call is directed, and wherein the call is routed through the at least one switch toward the destination communication device in response to whether the called number comprises a toll-free long-distance number and in response to whether the identity of the originating communication network is associated with a predetermined telecommunications carrier.

17. The method of claim 16, wherein the call is routed through the at least one switch toward the destination communication device in response to whether the called number comprises a toll-free long-distance number that is associated with the predetermined telecommunications carrier.

18. The method of claim 15, wherein the call is routed through the at least one switch toward the destination communication device in response to a called party address in a SS7 call query.

19. The method of claim 15, further comprising:

determining an association between the called number to which the call is directed and a plurality of call numbers that are associated with a predetermined telecommunications carrier in response to the call,

wherein the call is routed through the at least one switch toward the destination communication device in response to the determined association.

20. The method of claim 12, further comprising:

within a database, associating network identifications with phone numbers, alternate carrier identification codes, and alternate phone numbers;

identifying a called number to which the call is directed; and

identifying an alternate carrier identification code and an alternate phone number in response to the identity of the originating network and a called number to which the call is directed,

wherein the call is routed through the at least one switch toward the destination communication device in response to the identified alternate carrier identification code and the identified alternate phone number.

21. The method of claim 12, wherein the call is routed to a first destination when the identify of the originating communication network corresponds to a predetermined telecommunications carrier and the call is routed to a second destination when the identity of the originating communication network does not correspond to the predetermined telecommunications carrier.
