Abstract

Methods and system are disclosed for redirecting caller identification in an advanced intelligent network. The system comprises a service switching point and a service control point. When a redirected call is received at the service switching point, the service switching point places the call on hold and forwards a request to the service control point. The service control point recognizes that the call has been redirected and formats the caller identification information associated with the call to identify the telephone number from which the call was redirected. The re-formatted caller identification information is returned to the service switching point. The service switching point forwards the call to the destination telephone station using a distinctive ring to identify that the call has been redirected. The reformatted caller identification information, including the number of the telephone station from which the call was redirected, is forwarded to the destination telephone station.

Claims

1. In an advanced intelligent network, a system for identifying to a called party a telephone station from which a call has been forwarded, comprising:

a service control point adapted to detect whether a call directed to a first telephone station has been forwarded from a second telephone station and format call signaling information to identify the second telephone station from which the call was forwarded, said call signaling information identifying to a called party a telephone station from which a call has been forwarded, and

a service switching point in communication with said service control point, said service switching point adapted to suspend a call directed to the first telephone station and forward call signaling information associated with the call to said service control point.

2. The system of claim 1, wherein the signaling information is in SS7 format.

3. The system of claim 1, wherein said service control point is further adapted to forward signaling information designating the second telephone station from which the call was forwarded to said service switching point.

4. The system of claim 3, wherein said service switching point is further adapted to forward the call signaling information designating the second telephone station from which the call was forwarded to an end user telephone station.

5. The system of claim 3, wherein said service switching point is further adapted to cause a distinctive ringing pattern to be forwarded to an end user telephone station to identify that the call has been forwarded from the second telephone station.

6. The system of claim 1, wherein said service control point is further adapted to format the call signaling information to designate a third telephone station from which the call originated and a name associated with the third telephone station from which the call originated.

7. The system of claim 1, further comprising a signal transfer point for routing communications between said service control point and said service switching point.

8. In an advanced intelligent network, a method of identifying to a called party that a call has been forwarded from another telephone station, comprising:

at a service switching point in communication with a first telephone station, receiving a call directed to the first telephone station and forwarding a request to a service control point to detect whether the call was forwarded from a second telephone station;

at the service control point, detecting whether the call was forwarded from a second telephone station, and if the call was forwarded, formatting information designating the second telephone station from which the call was forwarded;

at the service switching point, forwarding to the first telephone station the information identifying the second telephone station from which the call was forwarded.

9. The method of claim 8, wherein said act of forwarding a request to a service control point to detect whether the call was forwarded comprises activating a trigger.

10. The method of claim 8, wherein formatting information designating the second telephone station from which the call was forwarded comprises including information indicating that the call was forwarded and the phone number associated with the second telephone station from which the call was forwarded.

11. The method of claim 8, further comprising at the service switching point forwarding the call to the first telephone station using a distinctive ring identifying that the call was forwarded.

12. The method of claim 8, wherein said act of formatting information designating the second telephone station from which the call was forwarded further comprises including information identifying a third telephone station from which the call originated and a name associated with the third telephone station from which the call originated.

13. In an advanced intelligent network, a method of identifying to a called party that a call has been forwarded from another telephone station, comprising:

receiving a request to identify whether a call has been forwarded from another telephone station;

reformatting caller identification information to include an indication of the telephone station from which the call was forwarded; and

forwarding the reformatted caller identification information to a called party.

14. The method of claim 13, wherein receiving a request to identify whether a call has been forwarded from another telephone station comprises receiving caller identification information identifying the telephone station from which the call originated and the telephone number from which the call was forwarded.

15. The method of claim 13, wherein reformatting caller identification information to include an indication of the telephone station from which the call was forwarded comprises reformatting caller identification information to further include a name associated with the telephone station from which the call originated.

16. The method of claim 13, further comprising querying a database to identify a name associated with the telephone station from which the call originated.
