US 2006/0215637 A1 · Visual communication server, visual communication program and visual communication method

Abstract

A VC server 1 has a call management unit 14 which detects a line connection state of telephone terminals based on an event signal received from an exchange 3 and registers the line connection state in a call information DB 11, a client information DB 10 in which telephone numbers of the telephone terminals and IDs of VC clients are stored in correspondence, a client connection information DB 12 in which session states between VC clients are stored, and a client session controller 15 which, when a change in line state between the telephone terminals is detected in the call information DB 11, refers to the client information DB 10, specifies a pair of corresponding VC clients, and instructs to establish or terminate a session between the VC clients according to the change in line state.

Claims15

Dependent claims

A visual communication server coupled to an exchange which controls a line connection between telephone terminals and to client computers arranged corresponding to the respective telephone terminals so as to perform communication of visual data imaged by a camera, the visual communication server comprising:

a call information event receiving unit which receives from the exchange a call information event generated by a behavior of the telephone terminal;
a telephone terminal state detecting unit which detects a line state between the telephone terminals based on the call information event received by said call information event receiving unit;
and
a controller which establishes or terminates according to the line state between the telephone terminals detected by said telephone terminal state detecting unit a session for the visual data communication between the client computers arranged corresponding to the telephone terminals.

1 more element

A visual communication program configured to execute processes in a visual communication server coupled to an exchange which controls a line connection between telephone terminals and to client computers arranged corresponding to the respective telephone terminals so as to perform communication of visual data imaged by a camera, the visual communication program comprising functions where the visual communication server:

receives from the exchange a call information event generated by a behavior of the telephone terminal;
detects a line state between the telephone terminals based on the received call information event;
and
establishes or terminates according to the detected line state between the telephone terminals a session for the visual data communication between the client computers arranged corresponding to the telephone terminals.

1 more element

A visual communication method for a visual communication server coupled to an exchange which controls a line connection between telephone terminals and to client computers arranged corresponding to the respective telephone terminals so as to perform communication of visual data imaged by a camera, the visual communication method comprising:

receiving from the exchange a call information event generated by a behavior of the telephone terminal;
detecting a line state between the telephone terminals based on the received call information event;
and
establishing or terminating according to the detected line state between the telephone terminals a session for the visual data communication between the client computers arranged corresponding to the telephone terminals.
