Abstract
A computer system has a presence server having a presence management unit that carries out a processing associated with presence data; and a conference management server that carries out a control processing of a conference. Then, when a request of an image delivery to another participant of a voice-based teleconference is received from a terminal of a first participant of the voice-based teleconference, the conference management server secures a resource for the image delivery, and transmits a presence setting request to the presence server so that the first participant and another participant can subscribe data concerning the resource for the image delivery. In addition, in response to the presence setting request, the presence management unit of the presence server carries out a setting so that the first participant and another participant can subscribe the data concerning the resource for the image delivery as presence data, which is delivered to subscribers when updated.
