Abstract

Various embodiments provide an apparatus and method for handling dynamic payloads in a heterogeneous network. An example embodiment includes a first node interface to receive a first request for data communication from a first node, the first request being coded in a first protocol and including information identifying a first payload type. The example embodiment includes a second node interface to receive a second request for data communication from a second node, the second request being coded in a second protocol and including information identifying a second payload type. The first node interface of the example embodiment configures a message coded in the first protocol to include the information identifying the second payload type and to send the message to the first node.

Claims

1. A method comprising:

receiving a first request for data communication from a first node, the first request being coded in a first protocol and including information identifying a first payload type;

receiving a second request for data communication from a second node, the second request being coded in a second protocol and including information identifying a second payload type;

configuring a message coded in the first protocol to include the information identifying the second payload type; and

sending the message to the first node.

2. The method as claimed in claim 1 wherein the first protocol is H.323 protocol.

3. The method as claimed in claim 1 wherein the first protocol is Session Initiation Protocol (SIP) protocol.

4. The method as claimed in claim 1 wherein the message coded in the first protocol to include the information identifying the second payload type is an Open Logical Channel (OLC) message.

5. The method as claimed in claim 1 wherein the message coded in the first protocol to include the information identifying the second payload type is a SIP Invite message.

6. An apparatus comprising:

means for receiving a first request for data communication from a first node, the first request being coded in a first protocol and including information identifying a first payload type;

means for receiving a second request for data communication from a second node, the second request being coded in a second protocol and including information identifying a second payload type;

means for configuring a message coded in the first protocol to include the information identifying the second payload type; and

means for sending the message to the first node.

7. The apparatus as claimed in claim 6 wherein the first protocol is H.323 protocol.

8. The apparatus as claimed in claim 6 wherein the first protocol is Session Initiation Protocol (SIP) protocol.

9. The apparatus as claimed in claim 6 wherein the message coded in the first protocol to include the information identifying the second payload type is an Open Logical Channel (OLC) message.

10. The apparatus as claimed in claim 6 wherein the message coded in the first protocol to include the information identifying the second payload type is a SIP Invite message.

11. An intermediate gateway apparatus comprising:

a first node interface to receive a first request for data communication from a first node, the first request being coded in a first protocol and including information identifying a first payload type;

a second node interface to receive a second request for data communication from a second node, the second request being coded in a second protocol and including information identifying a second payload type; and

the first node interface to configure a message coded in the first protocol to include the information identifying the second payload type and to send the message to the first node.

12. The apparatus as claimed in claim 11 wherein the first protocol is H.323 protocol.

13. The apparatus as claimed in claim 11 wherein the first protocol is Session Initiation Protocol (SIP) protocol.

14. The apparatus as claimed in claim 11 wherein the message coded in the first protocol to include the information identifying the second payload type is an Open Logical Channel (OLC) message.

15. The apparatus as claimed in claim 11 wherein the message coded in the first protocol to include the information identifying the second payload type is a SIP Invite message.

16. A system comprising a plurality of network elements including an originating endpoint, an intermediate gateway and a target endpoint, the intermediate gateway including:

a first node interface to receive a first request for data communication from a first node, the first request being coded in a first protocol and including information identifying a first payload type;

a second node interface to receive a second request for data communication from a second node, the second request being coded in a second protocol and including information identifying a second payload type; and

the first node interface to configure a message coded in the first protocol to include the information identifying the second payload type and to send the message to the first node.

17. The system as claimed in claim 16 wherein the first protocol is H.323 protocol.

18. The system as claimed in claim 16 wherein the first protocol is Session Initiation Protocol (SIP) protocol.

19. The system as claimed in claim 16 wherein the message coded in the first protocol to include the information identifying the second payload type is an Open Logical Channel (OLC) message.

20. The system as claimed in claim 16 wherein the message coded in the first protocol to include the information identifying the second payload type is a SIP Invite message.
