Abstract

Relates to arrangements for utilizing an originating caller'"'"'s customer network identifier (ONI) to provide special treatment of a call, especially one that terminates outside the caller'"'"'s network. The ONI is recognized in an originating switching system and is transmitted in an initial address message (IAM) to the terminating switching system for serving the call. In the terminating switching system, the ONI is used to screen the call for special treatment such as denied termination, denied termination for collect calls, or direct completion to a principal of a principal-secretary group. The ONI is also used for screening for use of originating services for members of a network. The originating or terminating switch can also query a data base to obtain screening data.

Claims

1. A method of identifying an originating customer network to a terminating network for a call comprising the steps of:

identifying an originating customer network of a caller of said call by determining its originating network identification (ONI);

delivering said call across a network boundary as determined by said ONI not matching a network identification of said terminating network,

transmitting said ONI of said customer network to a terminating switching system in said terminating network serving said call; and

delivering said ONI to a called party.

2. The method of claim 1 further including making a terminating translation based on a called telephone number of said call and on said delivered ONI.

3. The method of claim 1 wherein said ONI is transmitted in an Initial Address Message.

6. The method of claim 1 wherein said identifying comprises making an originating translation for said caller in an originating switching system of said call.

7. The method of claim 6 wherein said transmitting comprises transmitting from said originating switching system.

8. The method of claim 1 wherein the step of transmitting comprises transmitting over a common channel signaling (CCS) system.

9. The method of claim 1 further including using said delivered ONI and said identification of a called customer for determining which one of a plurality of special screening treatment should be provided for said call.

10. The method of claim 9 wherein said special screening treatment comprises denial of a requested service.

4. In a telecommunications switching system, apparatus for providing special screening terminating treatment to a telecommunications call, comprising:

means for receiving a common channel signaling message, said message comprising an ONI (originating network identifier) of a calling customer'"'"'s network, and an identification of a called customer;

means for determining whether said ONI and a network identifier of a terminating network receiving said call are different;

a screening table for screening incoming calls responsive to said determining means determining that said ONI and a network identifier of said terminating network receiving said call are different; and

means, responsive to receipt of said message said identification of a called customer and said ONI, and using said screening table for determining what special screening treatment should be provided for said call.

5. The apparatus of claim 4 wherein said message is an Initial Address Message.

11. The invention of claims 9 or 4 wherein said special screening treatment comprises denied call completion.

12. The invention of claims 9 or 4 wherein said special screening treatment comprises completion to a principal'"'"'s telephone.

13. The invention of claims 9 or 4 wherein said special screening treatment comprises automatic direct completion to an attendant'"'"'s telephone.

14. The invention of claims 9 or 4 wherein said special screening treatment comprises denied call completion for collect calls.

15. The invention of claims 9 or 4 wherein said special screening treatment comprises forwarding the call.

16. The invention of claims 9 or 4 wherein said special screening treatment comprises placing the call initially on hold.

17. The invention of claims 9 or 4 wherein said special screening treatment comprises providing priority ringing to said call.

18. The invention of claims 9 or 4 wherein said special screening treatment comprises forwarding said call to a preselected voice mailbox.

19. The invention of claims 9 or 4 wherein said special screening treatment comprises denying access to voice mail.

20. A method of providing special screening treatment to a telecommunications call comprising the steps of:

identifying a customer network of a caller of said call;

identifying a customer network of a called party of said call;

transmitting the identification of said caller customer network, an ONI (originating network identifier), and of said called party customer network, a TNI (terminating network identifier), to a data base system for serving said call;

means for determining whether said ONI and said TNI are different;

responsive to said determining means determining that said ONI and TNI are different;

using said ONI and said TNI for determining what special screening treatment should be provided for said call; and

transmitting data representing said special screening treatment to a switching system for serving said call.
