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.

Claims

1. A communication method executed by a participant terminal of a teleconference, comprising:

receiving information concerning a resource for image data delivery, wherein said information concerning said resource for said image data delivery is delivered from a server when said server receives an image delivery request from a terminal of a first participant of a voice-based teleconference and is managed as first presence data, which is delivered to subscribers when updated;

receiving second presence data concerning a state of said first participant, wherein said second presence data is delivered by said server when image data corresponding to said image delivery request is stored from said terminal of said first participant to said server; and

obtaining said image data from said resource for said image data delivery by using said information concerning said resource for said image data delivery, which is included in said first presence data received at said first receiving, after said second presence data was received.

2. A portable terminal, comprising:

a presence data processor that receives information concerning a resource for image data delivery, wherein said information concerning said resource for said image data delivery is delivered from a server when said server receives an image delivery request from a terminal of a first participant of a voice-based teleconference and is managed as first presence data, which is delivered to subscribers when is updated, and receives second presence data concerning a state of said first participant, wherein said second presence data is delivered by said server when image data corresponding to said image delivery request is stored from said terminal of said first participant to said server; and

an image processor that obtains said image data from said resource for said image data delivery by using said information concerning said resource for said image data delivery, which is included in said first presence data, after said second presence data is received.
