Abstract

PURPOSE:To execute sophisticated service without revision of exchange software without the need for a special exchange by adopting the multi-point conference controller independently of signal processing of the exchange. CONSTITUTION:A controller 105 and a signal processing unit 104 controlling the connection between the multi-point conference service processing unit 103 and an exchange 101 are provided independently of a controller 107 and a signal processing unit 106 controlling the exchange operation of the exchange 101. Then the signal processing unit 104 receiving a destination telephone number implements connection processing to a received destination telephone number together with the signal processing unit 106. In this processing, idle subscriber terminals among plural subscriber terminals accommodated in the exchange 101 connected to the multi-point conference service processing unit 103 are extracted and connected by using it. For example, when a destination telephone number is a participation terminal equipment 1091 of a group A implementing multi-point conference, one-to-one connection through the path of the multi-point conference service processing unit 103-exchange 101-participating terminal equipment 1091 is conducted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video conference connection system, and more particularly to a multi video conference connection system in which a plurality of video conference terminals installed at remote locations are connected via a communication network such as a broadband integrated service digital network. It relates to a point-to-point video conference connection system.

2. Description of the Related Art As a multipoint video conference connection system, a calling side sets a plurality of destinations to make a call to hold a multipoint meeting, and a multipoint meeting service process is performed by an exchange that accommodates a calling side terminal. After calling to the ground and confirming the response, the multipoint conference control device accommodated as part of the exchange is controlled from the exchange to perform voice synthesis, screen division, etc.
A method of distributing to each ground is generally known.

[0003] Normally, a general connection of an exchange is to make a one-to-one connection with a designated partner. However, when attempting a conference connection, it is necessary to adopt a complicated method of connecting 1 to n to the exchange itself for the purpose of making a 1 to n connection, and regarding the calling subscriber,
A method for enabling designation of a plurality of opposite subscribers is required, and a specialized exchange in which a number of complicated methods are superposed is required.

[0004]

In the conventional multi-point video conference connection system described above, the multi-point conference service processing is configured to be performed by the specialized exchange that accommodates the originating side terminal. Along with the sophistication of point conference service processing, when adding a service, a huge amount of switching software has to be changed, which results in a specialized network and it takes a lot of time to add the service.

Further, in the case of multiple access to a multipoint conference, there is a problem in that the signal processing of the exchange is significantly changed each time and the time required for the change becomes long.

The present invention has been made in view of the problems of the prior art as described above, and does not require a special exchange and can perform high-performance services without changing the exchange software. It is an object of the present invention to realize a network-independent multi-point video conference device capable of performing.

[0009]

The present invention is designed to eliminate the complications of the prior art, that is, the switch is dedicated to the well-known technique of simply making a one-to-one connection.

Specifically, a control device and a signal processing device for controlling the connection between the multipoint conference service processing device and the exchange, which are provided for the purpose of achieving the conference connection, and a control device for controlling the exchange operation of the exchange. And the signal processing device are provided independently.

The structure of the present invention will be described. In the multipoint conference service processing apparatus, the telephone number of the other party subscriber who is going to connect with the calling subscriber is transmitted and received.
An empty subscriber terminal of a subscriber terminal provided with a plurality of terminals is extracted according to the connection destination subscriber telephone number, and a plurality of connection subscriber telephone numbers that have already been received are assigned to each connection destination telephone number and called. It is conceivable to provide means for doing so.

Further, between the subscriber terminal which has reached these connections and the above-mentioned called subscriber terminal, there are a plurality of terminal interface means and a device unique to the multipoint conference service such as a voice mixing device, an image synthesizing device, and the like. The multipoint service processing device, which is composed of a device and a control means for sending and receiving terminals, is accommodated in the exchange in the same manner as the terminal, and in the signal processing of the exchange, the accommodation port of the terminal interface of the multipoint service processing device is maximum. It is a special number group for multiple numbers, a means for capturing an empty port of the special number group by a representative special number is provided in advance, and the exchange has a means for having a representative special number connection function, which is a known technology, and a one-to-one communication function with voice / image as well. Means may be provided.

With the above-mentioned configuration, the special number recognition issued from the calling terminal (conference organizer terminal) is used to perform a one-to-one connection to receive an incoming call to an empty port of the special number group of the multipoint service processing device, thereby performing multipoint service processing. The device responds to the calling terminal, and the terminal interface unit possesses it based on the ground information received by the calling terminal in the terminal-to-terminal communication, confirms the response, and notifies the calling terminal of the ground connection status sequentially. By controlling the unit independently of the exchange, the multipoint conference can be realized without providing the multipoint conference function in the exchange.

Furthermore, the participant terminal 10 of the group A is set to the destination telephone number.
If 9 _{2 is} also included, a vacant subscriber terminal is similarly extracted and one-to-one connection is performed.

Here, although detailed functional blocks in the multipoint conference control device are omitted in the figure, as described above, in the case of the audio mixing device portion and the video conference, the multipoint conference such as the image synthesizing device portion is performed. It has the configuration required above.

Further, as shown in FIG. 1, when a call is made from the host terminal 110 forming the group B and the special number dial is made, if the group A is already in the conference connection state, The exchange 101 captures an empty subscriber terminal among a plurality of subscriber terminals of the multipoint conference service processing device 103, and the sponsor terminal 110-exchange 10
1 One-point multi-point conference service processing device 103 is connected by a route. Thereafter, similarly to the above-mentioned group A, with respect to the group B as well, other empty subscriber terminals of the multipoint conference apparatus are extracted by the destination telephone number issued by the sponsor B, and the one-to-one connection is made via the exchange 101. Is done.

[0024]

Since the present invention is constructed as described above, it has the following effects.

In the system according to claim 1 and the system according to claim 2, since the multipoint conference control device configuration is independent of the signal processing of the exchange, it is realized by a general-purpose exchange that does not depend on the multipoint conference service. It is possible to provide a high-performance service by exchanging information between a terminal and a multipoint control device, such as conducting multiple simultaneous multipoint conferences, without changing the switching software.
