Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a conference connection system in an exchange.

[Conventional technology]

Conventionally, in this type of conference connection system, the number of subscribers who can participate in one conference is determined by the size of the conference trunk itself.

[Problem that the invention seeks to solve]

Therefore, if you want to add another subscriber during a conference connection, and the number of subscribers already connected is the maximum number of conference connections, you can either give up on adding the subscriber or add one subscriber to the currently connected subscriber. The method used was to restore people, empty the conference trunk, and make additional connections, resulting in lower service quality and more money.

[Means to solve all problems]

According to the present invention, in a digital time division exchange having a conference trunk, there is provided a means for any plurality of subscribers to perform all conference connections via the conference trunk, and a means for any subscriber connected to the conference (hereinafter referred to as a conference listener) to perform all conference connections via the conference trunk. Call at least one or more other subscribers (hereinafter referred to as conference listeners)
What about the meeting content from the conference trunk? A conference connection system characterized in that it includes a means for allowing a conference participant to connect to the conference trunk on behalf of any conference listener as necessary, and a means for returning to the original state as necessary. can get.

[Example p-.

Next, the present invention will be explained with reference to the drawings.

(a) and (b) of FIGS. 1 to 4 are a block diagram showing state changes in an embodiment of the present invention and a registration diagram of a registration table, respectively. In FIG. 1(a), when subscribers 1, 2, and 3a are in a conference on the conference trunk 6, the conference listening name registration provided corresponding to the conference trunk terminals 6a, 6b, and 6C as shown in FIG. 1←) In the γ-pulls 8a, 8b, and 8C, conference participants 1.2 and 3a are registered in the participant area, respectively, and the listening area is in an unregistered state.

At this point, the conference participant 3a requests the control section 7 to listen to the participants 3b and 3c by means of hooking + special number, etc.

After calling the subscribers 3b and 3c, the control unit 7 calls the conference trunk terminal 6ci connected to the output 1111 terminal 3ao of the conference participant 3a and the subscriber 3, as shown in FIG. 2(a).
Listening connection by connecting output terminals 3bO23co of b and 3c respectively? At the same time, as shown in FIG. 2(b), all conference listeners 3b and 3c are registered in the conference listening name registration table 8c corresponding to the conference trunk terminal 6CVC.

In the state shown in FIG. 2(a), when the conference participant 3a wants to fully disclose the opinions of the conference listener 3C, the conference participant 3a requests the control unit 7 to do so by means such as hooking + special number. In response to a request, the control unit 7 performs the following operations as shown in FIG. 3(a).
Conference participant 3a's input terminal 3al and conference trunk I
The I side terminal (ico) is fully opened and connected to the input terminal 3C1 of the conference listener 3C and the output terminal 6 CO' instead, and the conference listening name registration table 8C is connected as shown in FIG. 3 (1). All speaking display flags are set in the area where conference listener 3C is registered.

In this state, that is, in FIG. 3(a), conference participant 3
A can listen to the content of the conference, and if necessary, the control unit 7 can be used to return to the state shown in FIG. 2(a) by hooking or other means.
can be requested. That is, the control unit 7 searches the conference listening name registration table 8c in which the conference participant 3a is registered for an area where the speaking display flag is set, and selects the conference listening user 3C'? Find, release 3C4 and 5co and 3ai
This is done by connecting 5co and 5co. At the same time, the speaking display flag in the table 8C is cleared.

In addition, in the state shown in FIG. 2(a), conference listener 3C
If the person wishes to express his/her opinion, he/she requests the control unit 7 by means such as hooking. The control unit 7 uses a conference listening name registration table 8C in which the conference listeners 3C shown in FIG. 4(b) are registered.
A speaking request flag is registered in the area where 3.C is registered, and the meeting participant 3a registered in the table 8C is notified of the secret money requesting to speak. If the notification method is an audible sound, the interrupt sound generator 9 is connected to the conference participant output terminal 3fo for a very limited period of time as shown in FIG. Diagram (a)
Eli is done to return to.

At this time, the conference listener 3C can grant full permission to speak to the subscriber who has requested it, if necessary.

That is, by means such as hooking, the control unit 7 searches for the requester 3ci from the area where the -1 call N request flag is set in the conference listener registration table 8c (Search [-1 Send N request flag), and uses the same method as described above.

At the same time, the state is changed to the state shown in FIG. 2(a), and the speaking request flag in the conference listening name registration table 8c is cleared.
