Abstract

PURPOSE:To facilitate the participation of a monitor conference terminal equipment into a conference device and its stopping by connecting a monitor conference terminal equipment taking part as a monitor into plural monitor conference terminal equipments connected serially having a conference device at its head to a monitor conference terminal equipment resident in the tail end at present. CONSTITUTION:When a monitor conference terminal equipment 7 takes part in the conference, one B-channel 8 of an ISDN is used for the connection of the monitor conference terminal equipment 7 to a conference equipment 1. Then the conference equipment 1 informs an address C of a terminal equipment 3 to the terminal equipment 7 to interrupt the channel 8. Then the terminal equipment 7 uses a channel 9 by using the address C to be connected to the terminal equipment 3 and the terminal equipment 3 sends conference information to the terminal equipment 7. On the other hand, when the terminal equipment 3 stops monitoring, channels 5,9 are interrupted and uses a channel 10 to inform stop of monitor to the conference equipment 1. Then the conference equipment 1 interrupts the channel 10 and uses a channel 11 l to inform an address B of the terminal equipment 2 to the terminal equipment 7 and interrupts the channel 11. Succeedingly, the terminal equipment 7 uses the channel 12 and connects to the terminal equipment 2 and the terminal equipment 2 sends the conference information to the terminal equipment 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for monitoring a teleconferencing system, and more particularly to a method for monitoring a teleconferencing system that allows easy monitoring of conference information.

E. Prior Art] In recent years, communication processing services using teleconferencing systems and the like that utilize telephone networks have been attracting attention.

For example, teleconferencing services enable participants to participate in conferences at remote locations by interconnecting conference equipment such as general telephones, public address telephones, or electronic blackboards equipped with switchboards. be. To realize such a service, it is necessary to have the ability for multiple subscribers to talk at the same time, and the ability to join or leave a meeting at will, ensuring call quality and setting up multiple paths when setting up a call. , addition/deletion of arbitrary buses during a conference, and handling of call control signals associated with disconnection of multiple paths when a call is disconnected.

In addition, as a method for monitoring a teleconferencing system, for example, a conference device and a monitoring meeting #! There is a method in which the terminals are connected in a star configuration and conference information is transmitted from the conference device to each monitor conference terminal, and a method in which the conference device and the monitor conference terminal are connected serially.

Regarding communication processing services, please refer to "Electronic Information and Communication Handbook, Institute of Electronics, Information and Communication Engineers Layer (+988),"
pp. 2201-2203''.

[Problem to be Solved by the Invention 1] In the above-mentioned prior art, when a teleconferencing system using a star connection method is configured, when a monitor conference terminal monitors a conference, the conference device needs to have as many lines as there are monitor conference terminals. In addition, in order to transmit conference information to each monitor conference terminal, the conference device requires high-speed processing power6.In addition, with the serial connection method, the When a conference terminal stops monitoring, the monitor conference terminal connected behind the monitor conference terminal that stops monitoring must also stop monitoring.

The purpose of the present invention is to improve such problems and to
To provide a method for monitoring a teleconference system, which makes it possible to easily participate in and cancel monitoring from a monitor session #t@ terminal to a conference device by using the basic interface of subscriber M (hereinafter abbreviated as ISDN). It is in.

[Means for Solving the Problems] In order to achieve the above object, the teleconference monitoring system of the present invention includes a conference device and a plurality of monitor conference terminals connected to an ISDN network.
In the method for monitoring a teleconferencing system serially connected to a conference device, the conference device includes a calling address of a monitor conference terminal, an address of a party to which the monitor conference terminal transmits conference information, and a message from which the monitor conference terminal receives conference information. Equipped with a means to manage the address of the other party (monitor participation clothes),
When a monitor conference terminal monitors a conference, the participating terminal makes a call connection to the conference device using one B channel of ISDN, and the conference device refers to the monitor participant terminal and
The address of the monitor conference terminal currently at the end is notified to that terminal, the monitor participation clothes are updated, the line is disconnected, and the participating terminal uses one B channel of ISDN.
Make a call using the address notified by the conference device, connect to the last monitor conference terminal, and receive conference information from there.
Also, if the monitor conference terminal stops monitoring the conference,
The discontinuing terminal disconnects the line with the monitor conference terminal connected to it, uses one B channel of ISDN to notify the conference device of the discontinuation of monitoring, and the conference device Search for the connection address necessary for reconfiguration and notify the monitor conference terminal from which the line was disconnected from the canceled terminal, and the monitor conference terminal that has been notified of the connection address uses one B channel of ISDN. The feature is that the conference device makes a call using the address notified by the conference device and connects.

[Effect]

In the present invention, when a monitor conference terminal participates in monitoring a conference device or cancels monitoring, an ISDN basic interface (one B channel) is used.

Furthermore, the monitor participant clothing provided in the conference device manages the calling address of the monitor conference terminal, the address of the other party to which the monitor conference terminal transmits conference information, and the address of the other party to which the monitor conference terminal receives conference information.

When a monitor conference terminal participates in the monitor conference device, it notifies the address of the last one of the multiple monitor conference terminals serially connected with the conference device as the most advanced one, and makes the monitor conference terminal that will participate in monitor participation the address of the last one of the multiple monitor conference terminals that are serially connected with the conference device as the leading edge. Connect the tail monitor to the conference terminal. Additionally, when a monitor conference terminal stops monitoring, it notifies the monitor conference terminal whose line has been disconnected of the connection address necessary for serial connection in order to reconfigure the system. , connect.

As a result, it is possible to easily participate in and cancel monitor participation from the monitor conference terminal to the conference device, without providing the conference device with as many lines as the monitor conference terminals or requiring high-speed processing capacity.
