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:

first receiving information concerning a resource for image data delivery, wherein said information, which is managed as first presence data, 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 said first presence data is delivered to subscribers when updated;

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

transmitting a request for said image data to said resource by using said information received at said first receiving, after said second receiving; and

third receiving said image data from said resource, after said transmitting.

2. A portable terminal, comprising:

a memory; and

a processor configured to execute a procedure by using the memory, the procedure comprising;

first receiving information concerning a resource for image data delivery, wherein said information, which is managed as first presence data, 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 said first presence data is delivered to subscribers when is updated;

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

transmitting a request for said image data to said resource by using said information received at said first receiving, after said second receiving; and

third receiving said image data from said resource after said transmitting.
