Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a conference call interrupting connection system capable of smoothly adding participants in a conference call system.

As a part of diversifying telephone exchange services, telephone conference systems are being put to practical use.

Even in this type of conference call system, there is a demand for a means for easily adding another subscriber during the conference.

[Conventional technology]

FIG. 2 is a diagram showing an example of a conventional telephone conference system.

In FIG. 2, the switching network 1 is provided with a conference device 2. The organizer 3 who wishes to hold the conference sends a special number for conference call to the exchange network 1 and is connected to the conference device 2, and then selects the date and time of the conference and the telephone numbers of the participants 4. The conference reservation information is registered by.

At the registered date and time, the control device 21 in the conference device 2
Calls the organizer 3 from the channel ch1 via the switching network 1, connects to the connection terminal vbt1 of the voice bridge circuit 23 and the PB receiver 24 via the communication paths p1 and pr1 in the time switch 22, and also registers. Participants 4 who have been assigned channels ch3 to chn
From the switch network 1 and the organizer 3 selects the special number for participation in the conference determined to be available for attendance, so that the channel ch3 via the communication paths p3 to pn in the time switch 22 is selected.
Through chn are connected to connection terminals vbt3 through vbtn. The control device 21 uses the channels ch1 and ch3 to chn connected to the connection terminals vbt1 and vbt3 to vbtn, and the switching network 1 as connection information between the sponsor 3 and the participants 4 and the voice bridge circuit 23. The telephone numbers dn1 and dn3 to dnn of the organizer 3 and the participants 4 connected to the channels ch1 and ch3 to chn are stored in the voice bridge circuit connection area 211.

When the organizer 3 selects a special number for holding a conference after the call of the participant 4 is completed, the organizer 3 and each participant 4 start a conference call via the voice bridge circuit 23. The audio bridge circuit 23 includes connection terminals vbt1 and vbt3 to vbtn.
A conference voice is created by superimposing a voice arriving from the conference terminal and distributed to the connection terminals vbt1 and vbt3 to vbtn. As a result, both the organizer 3 and each participant 4 can hear the conference voice.

In addition, when the subscriber 5 who has not joined yet is to participate in the conference call during the conference call, if the organizer 3 selects the special number for additional participation and the telephone number dn3 of the subscriber 5,
The control device 21, which has received the special number and the telephone number dn2 via the receiver 24, activates the adding mechanism 212.

The adding mechanism 212 calls the subscriber 5 from the channel ch2 through the switching network 1, disconnects the call path p1 between the channel ch1 set in the time switch 22 and the connection terminal vbt1, and then sets the call path pi. Then, the organizer 3 and the subscriber 5 are connected.

When the organizer 3 determines that the subscriber 5 can participate in the conference call, and selects the special number for conference participation, the additional mechanism 212, which has received the special number via the PB receiver 24, again enters the time switch 22. Set channel p1 and channel ch1 and connection terminal vbt
1 is connected, and the call path p2 is set in the time switch 22 to connect the channel ch2 and the connection terminal vbt2 to the call path pi.
To release.

As described above, the subscriber 5 can participate in the conference call performed via the voice bridge circuit 23, like the participants 4.

[Problems to be solved by the invention]

As is clear from the above description, in the conventional telephone conference system, the organizer 3 needs to call the subscriber 5 when the new subscriber 5 is to participate in the conference call being held. Therefore, if the target subscriber 5 could not immediately participate due to absence or the like, the organizer 3 had to call repeatedly until the subscriber 5 responded, which was inconvenient.

[Means for solving problems]

The present invention solves the above problems by taking the following means.

That is, according to the present invention, a subscriber who wants to participate in a conference call calls to the telephone network and selects a predetermined telephone number to interrupt-connect to the organizer during the conference call. When the organizer performs a predetermined operation, the subscriber is connected to the conference device.

[Action]

That is, according to the present invention, the subscriber who was initially unable to participate in the conference call can be interrupt-connected to the host who is in the conference call at the time when the participant can join the conference call, and the interrupted host 3 can make the conference call. By performing the operation for participating in the conference call, it becomes possible for the subscriber to participate in the conference call, and it becomes unnecessary for the organizer to repeatedly call the subscriber for additional participation.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a telephone conference interrupt connection system according to an embodiment of the present invention. The same reference numerals denote the same objects throughout the drawings.

In FIG. 1, the control device 21 in the conference device 2 is provided with an interrupt mechanism 213.

In FIG. 1, the organizer 3 is connected to the channel ch1 of the conference device 2 via the exchange network 1 and the participant 4 is connected to the channel ch via the exchange network 1 by the same process as in FIG.
Time switch in conferencing device 2 connected to 3 to chn
The communication paths p1, p3 to pn and pr1 are set in 22 and the organizer 3 and each participant 4 connect the connection terminal vb of the voice bridge circuit 23.
Connected to t1 and the connection terminals vbt3 to vbtn, it is assumed that the organizer 3 and each participant 4 are in a conference call via the voice bridge circuit 23.

In this state, when the subscriber 5 makes a call to participate in the ongoing conference call and selects the special number for the conference call, the subscriber 5 connects to the channel ch2 of the conference device 2 via the exchange network 1. Further, it is connected to the PB receiver 25 via the communication paths p2 and pr2 in the time switch 22. In this state, when the subscriber 5 selects the telephone number dn1 of the organizer 3, the PB receiver 25
The control device 21, which has received the telephone number dn1 via, activates the interrupt mechanism 213 and the addition mechanism 212.

The interrupt mechanism 213 searches the connection terminal vbt1 and the channel ch1 corresponding to the telephone number dn1 stored in the voice bridge circuit connection area 211, and puts the call path p1 set in the time switch 22 in the hold state. After setting the call path pa and notifying the occurrence of an interrupt connection from the voice response device 26,
Releases pa to set the communication path pi, channels ch1 and ch2
To connect. As described above, the organizer 3 is disconnected from the conference call via the temporary voice bridge circuit 23, and the call with the subscriber 5 becomes possible.

If the organizer 3, who decides that the subscriber 5 can participate in the conference call being held, selects the special number for conference participation, the additional mechanism
In the same process as in FIG. 2, 212 sets the communication paths p1 and p2 in the time switch 22 again to connect the channel ch1 and the connection terminal vbt1, and the channel ch2 and the connection terminal vbt2, and the communication path pi and Release pr2.

As is clear from the above description, according to the present embodiment, the subscriber 5 who wishes to participate in the conference call being held selects the predetermined special number and the telephone number dn1 of the organizer 3 so that the organizer 3 It becomes possible to interrupt the connection to and notify the organizer 3 of the desire to participate in the conference. When the organizer 3 who has heard the request for participation performs an operation for participating in the conference, it becomes possible for the subscriber 5 to participate in the conference call. Therefore, the organizer 3 does not need to repeatedly call the subscriber 5.

It should be noted that FIG. 1 is merely an embodiment of the present invention until now, and the configuration of the conference device 2 is not limited to that shown in the drawing, and many other variations are considered. In this case, the effect of the present invention does not change.

[Effects of the Invention] As described above, according to the present invention, in the telephone conference system, a subscriber who was initially unable to participate in the conference call can be interrupted and connected to the host who is in the conference call when the subscriber becomes available. By performing the operation for the interrupted organizer 3 to participate in the conference call, it becomes possible for the subscriber to participate in the conference call, and the organizer does not need to repeatedly call the subscribers to additionally participate. .
