DETAILED DESCRIPTION OF THE INVENTION A first embodiment of the present invention will be described below with reference to FIG. The telephony / streaming server 100 has a communication unit 101, an HTML unit 102, and a telephony / stream control unit 103. The stream-compatible mobile terminal devices 200 and 300 include communication units 201 and 301 and browser units 202 and 30, respectively.
2 and video units 203 and 303. The telephony / streaming server 100 and the stream-compatible mobile terminal devices 200 and 300 are connected to each other via a media information communication path (IP communication bus) 1. Stream-compatible mobile terminal device 2
00 and 300 are also connected to each other by the media information communication path 1.

The operation of the call control system with video data according to the present embodiment will be described below. Telephony / Streaming Server 100
BX (private branch exchange), home gateway,
A switching device such as an IAD (Integrated Access Device) is assumed, and the operation of the detailed embodiment will be described here by taking a button telephone and video control as an example. As a terminal, PD
The mobile phone is not limited to A, and streaming is not limited to video data.

In offices and business establishments, a device for connecting an extension telephone network and a public telephone network, that is, a telephone exchange device such as a button telephone device is generally used. This telephone exchange device is configured as a dedicated device for exchanging and controlling voice lines. Here, it has a telephony / streaming control unit 103 for controlling not only audio data but also stream of video data and the like.

First, regarding voice, the buttons and functions of the terminal operated by the call control have a fixed form for each button telephone, and the operation screen is determined for each telephone. The telephony / streaming server 100 has an HTML unit 102 having a function of generating a virtual telephone operation screen of a preset type and browsing the operation screen with a browser. The operation screen generated by the HTML unit 102 becomes a virtual key telephone.
The virtual telephone is accessed by the stream-compatible mobile terminal device 200, and is I / F'd to the browser unit via the communication unit 201. As a result, if there is an environment where IP communication is possible even outside the office, the media information communication path
Through 1, it becomes possible to operate the telephone as it is normally used in the office. This browser section has the function of displaying not only the function screen of the button telephone but also other streams.

Next, regarding video, video data can be input from the video section 203 of the stream-compatible portable terminal apparatus 200. For example, if the other party who is currently talking is the owner of the stream-compatible portable terminal apparatus 300, Via the communication unit 201, via the media information communication path 1,
The video data is transmitted to the stream compatible mobile terminal device 300, and the browser unit 30 is transmitted via the communication unit 301.
The video data can be acquired at 2. Of course, on the contrary, the stream-compatible mobile terminal device 300 is stored in the browser unit 202 of the stream-compatible mobile terminal device 200.
The video data input from the video section 303 is displayed. In other words, while fully using the functions of the button telephone,
A stream of video data and the like is also displayed so that the user can talk while looking at the face of the other party. It is assumed that the present embodiment is not limited to the PDA and may be a mobile phone or the like.

Next, a second embodiment of the present invention will be described with reference to FIG. The control system according to the present embodiment has a configuration in which, in addition to the configuration of FIG. 1, a telephony / streaming server 100 further includes a mixing unit 104. Here, a case where the stream-compatible mobile terminal device 400 is newly added will be described as an example. For example, it is assumed that the owners of the stream-compatible mobile terminal apparatus 200 and the stream-compatible mobile terminal apparatus 300 are talking with video data while displaying the function screen of the key telephone. At that time, when the owner of the stream-capable mobile terminal device 300 wants to transfer the call with the video data to the stream-capable mobile terminal device 400, it is a virtual button telephone,
Press the button displaying "Transfer" in the function displayed on the browser unit 302,
That is, a number (partner number) indicating the stream-compatible mobile terminal device 400 is designated. The transfer command is transmitted to the telephony / stream control unit 103 of the telephony / streaming server 100 via the media information communication path 1. The telephony / streaming server 100 newly issues a video call connection instruction to the stream-compatible mobile terminal device 200 and the stream-compatible mobile terminal device 400, whereby the stream-compatible mobile terminal device 200 and the stream-compatible mobile terminal device 300 are heretofore used. The voice data and video data that were being communicated by will also be connected peer-to-peer. of course,
Here, not only transfer but also control of holding only video data, holding of video data and audio data, and the like are possible.

Since the telephony / streaming server 100 has the mixing unit 104, the virtual telephone button is operated to mix the voice data and the video data with the mixing unit 104, and the stream-compatible telephone device is provided. It is also possible to have a video conference with three owners of 200, 300, and 400. Of course, as the number of stream-capable mobile terminal devices increases, it becomes possible to hold a four-party, five-party conference or the like.

The present embodiment is not limited to the button telephone, but may be a home gateway, a VoIP router, an IA.
A gateway device such as D may be used.
