Abstract
A method and system is disclosed for interworking between half-duplex and full-duplex conferencing. A half-duplex (HD) conference will be conducted through one conference server and will involve floor-control, a full-duplex (FD) conference will be conducted through another conference server, and the conference servers will exchange bearer traffic so as to cooperatively provide an HD/FD conference. When the HD conference server detects that any of the participating HD client stations holds the floor in the HD conference, the HD conference server directs the FD conference server to put the participating FD client stations in a listen-only mode with respect to the HD conference. On the other hand, when the HD conference server detects that none of the HD client stations holds the floor, the HD conference server directs the FD conference server to lift the listen-only restriction.
