Abstract

A system and method for the conversion of messages from one medium to another in an Intelligent Network (IN) telecommunications system comprising several Intelligent Peripherals (IPs) connected to a Service Control Point (SCP) over a network. The various IPs are also linked to each other over a distinct telecommunications backbone. The SCP orders a conversion IP to retrieve the received message over the telecommunications backbone and convert it to a specified medium, which may optionally be specified by the recipient. When the conversion process is complete, the SCP orders a delivery IP to retrieve and deliver the converted message to the intended recipient.

Claims

1. In a method for communicating in an IN (Intelligent Network) telecommunications system comprising a plurality of IPs (Intelligent Peripherals) connected to an SCP (Service Control Point) over a network, said plurality of IPs being further connected to each other over a distinct telecommunications backbone, an improvement of a method for converting a received-form message formed in a first medium into a converted-form message formed in a second medium, said method comprising the steps of:

providing the received-form message formed in the first medium to a recipient IP;

transporting the received-form message from the recipient IP to a conversion IP;

converting the received-form message at the conversion IP into the converted-form message formed in the second medium;

transporting the converted form message to a delivery IP; and

delivering the converted-form message formed in the second medium to the intended recipient of said message.

2. The method of claim 1 wherein at least two of the recipient IP to which the received-form message is provided, the conversion IP to which the received-form message is transported, and the delivery IP to which the converted-form message is transported are collocated.

3. The method of claim 1 wherein said IPs connected over a telecommunications backbone communicate with each other using the TCP/IP communications protocol.

4. The method of claim 1 wherein said IPs connected over a telecommunications backbone communicate with each other using the X.25 communications protocol.

5. The method of claim 1 wherein the received-form message comprises a non-call-related message.

6. The method of claim 1 wherein the received-form message is compatible with store-and-forward services.

7. The method of claim 1 wherein said first medium and said second medium are selected from the group consisting of voice-mail messages, e-mail messages, fax mail messages, messages in SMS (Short Message Service) format.

8. The method of claim 1 comprising the further intermediary step of notifying the SCP by the recipient IP of a change in status of a user'"'"'s mailbox and wherein said step of transporting the received-form message from the recipient IP to the conversion IP is performed in response to a notification of the SCP during said step of notifying.

9. The method of claim 1 comprising the further step of querying the recipient IP regarding a status of a user'"'"'s mailbox, and wherein said step of transporting the receivedform message from said recipient IP to said conversion IP is performed in response to the query from the SCP during said step of querying.

10. The method of claim 1 wherein said step of transporting said received first message from said recipient IP to said conversion IP is performed using a FETCH command.

11. The method of claim 1 wherein said step of converting the received-form message into said converted-form message is performed in conformity with a subscriber'"'"'s conversion and delivery preferences.

12. The method of claim 1 wherein said step of converting the received-form message into said converted-form message is performed using a CONVERT command.

13. The method of claim 1 wherein said step of delivering the converted-form second message formed in the second medium to the intended recipient of said message is performed using a SEND MESSAGE command.

14. In an IN (Intelligent Network) telecommunications system comprising a plurality of IPs (Intelligent Peripherals) connected to an SCP (Service Control Point) over a network, said plurality of IPs being further connected to each other over a distinct telecommunications backbone, a system for converting a first message received in a first medium into a second message in a second medium, said system comprising:

means for receiving said first message in said first medium into a recipient IP;

means for transporting said received first message from said recipient IP to a conversion IP;

means for converting said received first message in said conversion IP into said second message in said second medium;

means for transporting said converted second message to a delivery IP; and

means for delivering said converted second message in said second medium to the intended recipient of said message.

15. The media conversion system of claim 14 wherein two or more of the group comprising said recipient IP, said conversion IP and said delivery IP are physically collocated.

16. The media conversion system of claim 14 wherein said IPs connected over a telecommunications backbone communicate with each other using the TCP/IP communications protocol.

17. The media conversion system of claim 14 wherein said IPs connected over a telecommunications backbone communicate with each other using the X.25 communications protocol.

18. The media conversion system of claim 14 wherein said first message is a non-call-related message.

19. The media conversion system of claim 14 wherein said first message is compatible with store-and-forward services.

20. The media conversion system of claim 14 wherein said first medium and said second medium are selected from the group consisting of voice-mail messages, e-mail messages, messages in SMS (Short Message Service) format.

21. The media conversion system of claim 14 wherein said means for transporting said received first message from the recipient IP to a conversion IP is responsive to a notification to an SCP by said recipient IP of a change in the status of an user'"'"'s mailbox.

22. The media conversion system of claim 14 wherein said means for transporting said received first message from said recipient IP to said conversion IP is responsive to a query from an SCP to the recipient IP regarding the status of an user'"'"'s mailbox.

23. The media conversion system of claim 14 wherein said means for transporting said received first message from said recipient IP to said conversion IP comprises a FETCH command.

24. The media conversion system of claim 14 wherein said means for converting said received first message into said converted second message additionally comprises means for conforming the conversion with a subscriber'"'"'s conversion and delivery preferences.

25. The media conversion system of claim 14 wherein said means for converting said received first message into said converted second message comprises a CONVERT command.

26. The media conversion system of claim 14 wherein said means for delivering said converted second message in said second medium to the intended recipient of said message comprises a SEND MESSAGE command.

27. In an IN (Intelligent Network), apparatus for converting a received-form message formed in a first medium and originated by an originator into a converted-form message formed in a second medium, the converted-form message to be delivered to a subscriber, said apparatus comprising:

a recipient IP (Intelligent Peripheral) for receiving the received-form message originated by the originator;

a conversion IP (Intelligent Peripheral) coupled to said recipient IP, said conversion IP for converting the received-form message received by said recipient IP into the converted form message;
