AUTHORIZING INTER-USER EQUIPMENT SESSION TRANSFER

摘要

PROBLEM TO BE SOLVED: To solve the problem that it is difficult to distinguish between a request for transfer of media components and a request for replication of media components and it is difficult to determine if a device is able to perform replication of a session and to how often perform replication of a session.SOLUTION: A method of replicating a media session in a service centralized and continuity application server (SCC AS) includes steps of: receiving a collaborative replication session invite request from a second wireless transmit/receive unit (WTRU); allocating a media resource for a replicated media flow; transmitting a response for the replicated media flow in a media resource function (MRF) to the second WTRU; updating an access leg on a first WTRU for the replicated media flow using the MRF; and updating a remote leg for the replicated media flow in the MRF.
