Abstract

Methods and systems for resuming, transferring or copying an IMS session associated with a first terminal or user at a second terminal in e.g., a same household are described. If a session is to be transferred, resource reservations associated with establishing a second IMS session for the transfer can be bypassed by informing the IMS system, either explicitly or implicitly, of the relationship between the terminals involved in the transfer. A controller can select a content server to support the resumed session and coordinate session identities associated with the selection.

22. A method for replicating a media session comprising:

storing a first session identity, a content identity and a time reference associated with said media session;

receiving a command to resume said media session;

selecting one of;

a content server which previously supplied content associated with said media session and a new content server, to replicate said media session; and

transmitting a replication message including said content identity and said time reference toward said selected one of said content server which previously supplied content associated with said media session and said new content server which informs said selected server of replication of said media session.

23. The method of claim 22, wherein said replication message also includes said first session identity.

24. The method of claim 23, further comprising the steps of:

receiving, in response to said replication message, an indication that said selected content server cannot set up a new session using said first session identity;

transmitting, in response to said indication, a second session identity; and

associating said second session identity with said first session identity.

25. The method of claim 22, wherein said replication message includes a second session identity and further comprising:

associating said second session identity with said first session identity.

26. The method of claim 22, wherein said first session identity is a Real Time Streaming Protocol (RTSP) identity.

27. A system comprising:

a first node including;

a memory device for storing a first session identity, a content identity and a time reference associated with a media session; and

a processor for receiving a command to resume said media session, selecting one of;

a content server which previously supplied content associated with said media session and a new content server, to resume said media session; and

transmitting a replication message including said content identity and said time reference toward said selected one of said content server which previously supplied content associated with said media session and said new content server which informs said selected server of replication of said media session.

28. The system of claim 27, wherein said replication message also includes said first session identity.

29. The system of claim 28, wherein said processor receives, in response to said replication message, an indication that said selected content server cannot set up a new session using said first session identity, transmits, in response to said indication, a second session identity, and associates said second session identity with said first session identity.

30. The system of claim 27, wherein said replication message includes a second session identity wherein said processor associates said second session identity with said first session identity.

31. The system of claim 27, wherein said first session identity is a Real Time Streaming Protocol (RTSP) identity.

32. The system of claim 27, further comprising:

said content server which previously supplied content associated with said media session; and

said new content server.
