Privacy for inter-user equipment transfer (iut) subscribers and for remote parties involved in sessions with iut subscribers

Abstract

Systems, methods, and instrumentalities are disclosed to provide privacy for inter-user equipment transfer (IUT) subscribers and remote parties involved in sessions with IUT subscribers. A first UE may establish a session with a remote party. The first UE may seek to perform an IUT to a second UE. The first UE may send a first request for the IUT to a service centralization and continuity application server (SCC AS). The SCC AS may receive the first request and perform an authorization. The SCC AS may determine that the requested IUT is allowed for the session. The SCC AS may send a second request to the remote party indicating the requested IUT. The remote party may evaluate the second request and may accept or reject the second request.

What is claimed: 
     
         1 . A method for performing an inter user equipment transfer, the method comprising:
 receiving a first request for an inter user equipment transfer of a media component of a session;   determining that the requested inter user equipment transfer is allowed for the session;   sending a second request to a remote party indicating the requested inter user equipment transfer; and   receiving an acceptance of the requested inter user equipment transfer from the remote party.   
     
     
         2 . The method of  claim 1 , wherein the second request indicates an identity relating to a user equipment that is a target of the requested inter user equipment transfer. 
     
     
         3 . The method of  claim 2 , wherein the identity is a session initiation protocol identity. 
     
     
         4 . The method of  claim 1 , wherein the second request comprises a modified session description protocol message comprising an attribute, wherein the attribute indicates an identity of a user equipment that is a target of the requested inter user equipment transfer. 
     
     
         5 . The method of  claim 1 , wherein determining that the requested inter user equipment transfer is allowed for the session comprises determining that the session is not subject to digital rights management. 
     
     
         6 . The method of  claim 1 , further comprising sending a control message to the remote party for transfer of the media component to a user equipment that is a target of the requested inter user equipment transfer, wherein the control message is a modified session description protocol message. 
     
     
         7 . A service centralization and continuity application server, comprising:
 a receiver configured to receive a first request for an inter user equipment transfer of a media component of a session;   a processor configured to determine that the requested inter user equipment transfer is allowed for the session; and   a transmitter configured to send a second request to a remote party indicating the requested inter user equipment transfer; and   wherein the receiver is further configured to receive an acceptance of the requested inter user equipment transfer from the remote party.   
     
     
         8 . The service centralization and continuity application server of  claim 7 , wherein the second request indicates an identity relating to a user equipment that is a target of the requested inter user equipment transfer. 
     
     
         9 . The service centralization and continuity application server of  claim 8 , wherein the identity is a session initiation protocol identity. 
     
     
         10 . The service centralization and continuity application server of  claim 7 , wherein the second request comprises a modified session description protocol message comprising an attribute, wherein the attribute indicates an identity of a user equipment that is a target of the requested inter user equipment transfer. 
     
     
         11 . The service centralization and continuity application server of  claim 7 , wherein to determine that the requested inter user equipment transfer is allowed for the session comprises determining that the session is not subject to digital rights management. 
     
     
         12 . The service centralization and continuity application server of  claim 7 , wherein the transmitter is further configured to send a control message to the remote party for transfer of the media component to a user equipment that is a target of the requested inter user equipment transfer, wherein the control message is a modified session description protocol message.
