Abstract

A Session Initiation Protocol (SIP) message adapted for use by a multi-media services provider system to form a multi-media communication path between at least a calling communication device adapted to operate using a first protocol (e.g. SIP) and at least a destination communication device adapted to operate using a second protocol, such as Integrated Services Digital Network User Part (ISUP). The SIP message includes a header region having a number of header fields, a first body region having Session Description Protocol (SDP) information related to the calling communication device and a second body region having ISUP related addressing information associated with the destination communication device.

Claims

1. A method of forming a multi-media communication path between a calling communication device that operates using a first protocol and a destination communication device that operates using a second protocol, comprising:

receiving a request for a multi-media service at a call control element of a multi-media provider system;

processing the request at the call control element for generating a signaling protocol message; and

sending the signaling protocol message to the destination communication device to form the multi-media communication path between the calling communication device and the destination communication device, wherein the destination communication device comprises a circuit based communication device and wherein the signaling protocol message includes a header portion, a first body portion and a second body portion separate from and different than the header portion and the first body portion, wherein the second body portion includes predetermined address specific information associated with the destination communication device and privacy information associated with the calling communication device, wherein the privacy information indicates whether an identity of the calling communication device is to remain private in accessing the multi-media service.

2. The method of claim 1, wherein the generating the signaling protocol message at the call control element includes providing address specific integrated services digital network user part signaling information in the second body portion of the signaling protocol message.

3. The method of claim 2, wherein the providing the integrated services digital network user part signaling information includes providing nature of address information.

4. The method of claim 3, wherein the providing the integrated services digital network user part signaling information further includes providing numbering plan type information.

5. The method of claim 4, wherein the providing the integrated services digital network user part signaling information further includes providing calling party number information.

6. The method of claim 5, wherein the providing the integrated services digital network user part signaling information further includes providing privacy restriction indicator information.

7. The method of claim 6, wherein the providing the integrated services digital network user part signaling information further includes providing screening indicator information.

8. The method of claim 7, wherein the providing the integrated services digital network user part signaling information further includes providing a plurality of alpha-numeric values arranged into a predetermined number of signaling parameters representing the integrated services digital network user part signaling information.

9. A system of forming a multi-media communication path between a calling communication device that operates using a first protocol and a destination communication device that operates using a second protocol, comprising:

means for receiving a request for a multi-media service at a call control element of a multi-media provider system;

means for processing the request at the call control element for generating a signaling protocol message; and

means for sending the signaling protocol message to the destination communication device to form the multi-media communication path between the calling communication device and the destination communication device, wherein the destination communication device comprises a circuit based communication device and wherein the signaling protocol message includes a header portion, a first body portion and a second body portion separate from and different than the header portion and the first body portion, wherein the second body portion includes predetermined address specific information associated with the destination communication device and privacy information associated with the calling communication device, wherein the privacy information indicates whether an identity of the calling communication device is to remain private in accessing the multi-media service.

10. The system of claim 9, wherein the generating the signaling protocol message at the call control element includes providing address specific integrated services digital network user part signaling information in the second body portion of the signaling protocol message.

11. The system of claim 10, wherein the providing the integrated services digital network user part signaling information includes providing nature of address information.

12. The system of claim 11, wherein the providing the integrated services digital network user part signaling information further includes providing numbering plan type information.

13. The system of claim 12, wherein the providing the integrated services digital network user part signaling information further includes providing calling party number information.

14. The system of claim 13, wherein the providing the integrated services digital network user part signaling information further includes providing privacy restriction indicator information.

15. The system of claim 14, wherein the providing the integrated services digital network user part signaling information further includes providing screening indicator information.

16. The system of claim 15, wherein the providing the integrated services digital network user part signaling information further includes providing a plurality of alpha-numeric values arranged into a predetermined number of signaling parameters representing the integrated services digital network user part signaling information.
