System and method for implementing media and media transfer between devices

Abstract

A method to transfer control is presented. The method includes receiving a request to transfer control of a collaborative session from a first user equipment (UE). The method includes sending a request for the transfer of control of the collaborative session in response to the received request to a second UE, and receiving, in response to the sent request to the second UE, an indication of acceptance of the transfer of control of the collaborative session. The method includes sending a notification of status to the first UE of the control of the collaborative session in response to receiving, from the second UE, the indication of acceptance.

1 . A method to transfer control, comprising:
 receiving a request to transfer control of a collaborative session from a first user equipment (UE);   sending a request for the transfer of control of the collaborative session in response to the received request to a second UE;   receiving, in response to the sent request to the second UE, an indication of acceptance of the transfer of control of the collaborative session;   sending a notification of status to the first UE of the control of the collaborative session in response to receiving, from the second UE, the indication of acceptance.   
     
     
         2 . The method of  claim 1 , wherein the received response is encoded as session initiation protocol (SIP). 
     
     
         3 . The method of  claim 2 , wherein the SIP message is a SIP REFER message. 
     
     
         4 . The method of  claim 1 , further comprising sending a NOTIFY message indicating success in response to receiving the request to transfer control. 
     
     
         5 . The method of  claim 1 , wherein the message requesting transfer of control of a collaborative session also comprises a request for media transfer. 
     
     
         6 . A network node, comprising:
 a processor, the processor being configured to:
 receive a request to transfer control of a collaborative session from a first user equipment (UE); 
 send a request for the transfer of control of the collaborative session in response to the received request to a second UE; 
 receive, in response to the sent request to the second UE, an indication of acceptance of the transfer of control of the collaborative session; 
 send a notification of status to the first UE of the control of the collaborative session in response to receiving, from the second UE, the indication of acceptance. 
   
     
     
         7 . The network node of  claim 6 , wherein the received response is encoded as SIP. 
     
     
         8 . The network node of  claim 7 , wherein the SIP message is a SIP REFER message. 
     
     
         9 . The network node of  claim 6 , further comprising sending a NOTIFY message indicating success in response to receiving the request to transfer control. 
     
     
         10 . The network node of  claim 6 , wherein the message requesting transfer of control of a collaborative session also comprises a request for media transfer. 
     
     
         11 . The network node of  claim 6 , wherein the network node includes a service consistency and continuity application server (SCC AS). 
     
     
         12 . A user equipment (UE), comprising:
 a processor, the processor being configured to:
 transmit a request to transfer control of a collaborative session from a first user equipment (UE); 
 receive a notification of status of the control of the collaborative session. 
   
     
     
         13 . The UE of  claim 12 , wherein the notification of status includes a NOTIFY message. 
     
     
         14 . The UE of  claim 12 , wherein the message requesting transfer of control of a collaborative session also comprises a request for media transfer.
