Abstract

A method and apparatus for providing an exchange server to couple multiple MMSCs, the exchange server including a queue to receive the MMS message if the recipient MMSC does not have bandwidth available.

Claims

1. An exchange relay to enable communication between disparate multimedia message service centers (MMSCs), the exchange relay comprising:

a receiving logic to receive a multimedia messaging service (MMS) message from an originating MMSC, the MMS message comprising at least one multimedia element;

clearinghouse logic to store copies of each multimedia element sent through the exchange relay in a clearinghouse, to determine if the at least one multimedia element in the MMS message has a better quality copy in the clearinghouse and, if so, to substitute the better quality copy from the clearinghouse into the MMS message;

a connection logic to attempt to establish a connection with a recipient MMSC to forward the MMS message to the recipient MMSC;

a process queue to temporarily buffer the MMS message;

a retry queue to store the MMS message received from the originating MMSC if the recipient MMSC is temporarily not available to receive the MMS message, wherein the MMS message stored in the retry queue is forwarded to the recipient MMSC once the recipient MMSC is available to receive the MMS message; and

a message trace generator to track progress of the MMS message through the exchange relay.

2. The exchange relay of claim 1, further comprising:

a throttling logic to control a rate of opening connections to the recipient MMSC.

3. The exchange relay of claim 2, wherein the throttling logic sends the MMS message from the process queue at a rate that is adjusted to an available bandwidth of the recipient MMSC.

4. The exchange relay of claim 2, wherein the throttling logic sends the MMS message from the process queue at a fixed rate determined by an agreement with the recipient MMSC.

5. The exchange relay of claim 2, wherein the throttling logic is further to control the number of incoming connections accepted from originating MMSCs.

6. The exchange relay of claim 1, further comprising an availability tester to determine whether the recipient MMSC is available, prior to or in conjunction with determining whether the recipient MMSC has the bandwidth to handle the MMS message.

7. The exchange relay of claim 1, further comprising:

an MMSC access control to determine whether the originating MMSC has access to the recipient MMSC, and to send an error message if the originating MMSC does not have access.

8. The exchange relay of claim 1, further comprising:

target capability lookup logic to determine a proper message format for the recipient MMSC, to ensure that messages sent to the recipient MMSC can be processed.

9. The exchange relay of claim 8, further comprising:

message size reduction logic to reduce the size of the MMS message, if a maximum message size accepted by the recipient MMSC is smaller than the size of the MMS message.

10. The exchange relay of claim 8, further comprising:

reformatting logic to reformat an element in the MMS message, if the recipient MMSC requires a different format for the element from an original format.

11. The exchange relay of claim 1, further comprising:

audit/report generation logic to generate one or more reports for each contracting MMSC.

12. The exchange relay of claim 1, further comprising:

DRM logic to verify forwarding rights for each multimedia element sent through the exchange relay, and to enable digital rights management of the multimedia elements.

13. The exchange relay of claim 1, further comprising:

a retry logic to handle undelivered MMS messages in the retry queue that have been undeliverable for a period of time.

14. The exchange relay of claim 13, wherein handling comprises archiving or purging the undelivered MMS messages.

15. The exchange relay of claim 13, further comprising:

an audit/report generation logic to notify the originating MMSC of undelivered MMS messages intended but not delivered to the recipient MMSC.

16. The exchange relay of claim 1, further comprising:

a service provider identification (SPID) lookup and additional logic to look-up the SPID of the originating MMSC and the recipient MMSC if needed; and

a message rewrite logic to add the SPID data to the MMS message.

17. The exchange relay of claim 16, wherein the SPID lookup is further designed to determine whether the SPID is already part of a message ID, to avoid performing an SPID look-up.

18. The exchange relay of claim 16, wherein adding the SPID to the MMS message enables sharing of SPID information across relay servers, thereby reducing the number of SPID look-ups.

19. The exchange relay of claim 16, further comprising:

the message rewrite logic further designed to rewrite the MMS message to remove the SPID information, if the SPID was added by the exchange relay, prior to sending out the MMS message to an MMSC.

20. The exchange relay of claim 16, further comprising:

the message rewrite logic further designed to encode information in a message ID associated with a message to add additional data used by the exchange relay during processing.

21. The exchange relay of claim 20, wherein the information comprises one or more of the following:

service provider identification (SPID) of the originating MMSC, SPID of the destination MMSC, and routing protocol to be used in communication with the originating MMSC.

22. The exchange relay of claim 20, wherein the message rewrite logic is further designed to rewrite the message ID to an original message ID, prior to returning data to the originating MMSC.

23. The exchange relay of claim 1, wherein

the message trace generator creates a message trace including the original message, an SPID of the originating MMSC, an SPID of the recipient MMSC, a message receipt time, and a message delivery time.

24. A method comprising:

receiving a multimedia messaging system (MMS) message from a first multimedia message service center (MMSC), the MMS message comprising at least one multi-media element;

storing copies of each multimedia element sent through the exchange relay in a clearinghouse;

determining if the clearinghouse has a better quality copy of the at least one multi-media element in the MMS message, and if so, substituting the better quality copy from the clearinghouse into the MMS message;

identifying a second MMSC to which the MMS message should be forwarded;

determining whether the second MMSC has bandwidth to handle the MMS message; and

if the second MMSC does not have bandwidth to handle the MMS message, storing the MMS message in a queue, wherein the MMS message is forwarded to the second MMSC once the second MMSC has bandwidth to handle the MMS message.

25. The method of claim 24, further comprising:

determining whether the recipient MMSC is available, prior to or in conjunction with determining whether the recipient MMSC has bandwidth to handle the MMS message.

26. The method of claim 25, further comprising:

using a pre-determined bandwidth value for the recipient MMSC to make the bandwidth determination.

27. The method of claim 24, further comprising:

determining when the recipient MMSC has bandwidth; and

sending accumulated MMS messages from the queue to the recipient MMSC at a throttled rate.

28. The method of claim 27, wherein the accumulated MMS messages from the queue are sent at a rate that is adjusted to the available bandwidth of the recipient MMSC.

29. The method of claim 24, further comprising:

archiving or purging undelivered MMS messages in the queue intended for the recipient MMSC that have been undeliverable for a period of time.

30. The method of claim 29, further comprising:

notifying the originating MMSC of the undelivered or archived MMS messages intended but not delivered to the recipient MMSC.

31. The method of claim 24, further comprising:

determining whether the originating MMSC has access to the recipient MMSC prior to sending the MMS message; and

sending an error message if the originating MMSC does not have access to the recipient MMSC.

32. The method of claim 24, further comprising:

determining a proper message format for the recipient MMSC, to ensure that messages sent to the recipient MMSC can be processed.

33. The method of claim 32, further comprising:

reducing the size of the MMS message, if a maximum message size accepted by the recipient MMSC is smaller than the size of the MMS message.

34. The method of claim 32, further comprising:

reformatting the MMS message, if the recipient MMSC requires a different format for the element from an original format.

35. The method of claim 24, further comprising:

generating a report for a contracting MMSC, in accordance with a form requested by the contracting MMSC.

36. The method of claim 24, further comprising:

verifying forwarding rights for each multimedia element sent through the exchange relay.

37. The method of claim 24, wherein a second MMSC that does not have the bandwidth to handle the MMS message includes a second MMSC that is not connected to a network.
