An association of videoconferencing services is disclosed that enables two
or more videoconferences to be generated with each videoconference
running independently from the others and having its own conferees. The
association is achieved by having at least one conferee (a traveler) that
can "move" or "travel" from one videoconference to another in the
association. The one or more travelers belong to the association and not
to any particular videoconference. In exemplary embodiments, the traveler
can choose between the various associated videoconferences by making a
selection to a multipoint control unit (MCU) that controls the associated
videoconferences.
