Abstract
A method (500) and apparatus (301) are described for establishing a video information stream (102) and a corresponding audio information stream (103) between an originating communication unit (110) having floor control and a target communication unit (120). A call is initiated to obtain floor control and a media path is established for transferring the video and audio information streams. The video information stream is established in a full duplex mode and the audio information stream is established in a half duplex mode using a Session Initiation Protocol (SIP). The call may include a peer to peer or a group call.
Claims20
A method for transmitting a video information stream and a corresponding audio information stream from an originating communication unit having floor control to a target communication unit, the method comprising:
- initiating a call from the originating communication unit to the target communication unit to obtain the floor control;
- and
- establishing a media path between the originating communication unit and the target communication unit for transferring the video information stream and the audio information stream between the originating communication unit and the target communication unit.
A method for transmitting a video information stream and a corresponding audio information stream from an originating communication unit to a target communication unit, the method comprising:
- initiating a call using a Session Initiation Protocol (SIP) from the originating communication unit to the target communication unit;
- and
- establishing a media path between the originating communication unit and the target communication unit using the SIP protocol, the media path for transferring the video information stream and the audio information stream between the originating communication unit and the target communication unit.
An apparatus capable of transmitting a video information stream and a corresponding audio information stream to a target communication unit in a Radio Access Network (RAN), the apparatus comprising:
- a RAN interface;
- a memory;
- and
- a processor coupled to the memory and the RAN interface, the processor configured to:
- initiate a call to the target communication unit when an activation event is detected;
- and
- establish a media path with the target communication unit over the RAN interface so as to transfer the video information stream in a full duplex mode to the target communication unit and so as to transfer the audio information stream in a half duplex mode to the target communication unit.
