JPH02281864A - Liberalizing system for called party in telephone conference system - Google Patents

Abstract

PURPOSE:To freely join from on the way of a telephone conference from the side of a called party by constituting this system so that the called party can join the telephone conference which is being performed by dialing a toll number + 1XY + a subscriber's number of a calling party of the calling person who is performing the telephone conference. CONSTITUTION:A called party 2 and a calling party 3 are already in a state that a telephone conference is being performed, and these subscribers are connected to a telephone conference equipment 6, respectively through a local switch 4 and a toll transit switch 5. In the case a called person 1 joins the telephone conference which is being performed, the subscriber (called person) 1 dials a toll number of the calling party 3 + 1XY in accordance with the participation sequence to the telephone conference. Thereafter, the called person 1 can join the telephone conference which is being performed. In such a way, it becomes unnecessary to interrupt the telephone conference which is being performed.

Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention provides a system in which a teleconference device is installed in a toll switchboard, and registered in advance through the teleconference device 1. A teleconferencing system that allows multiple calls between subscribers at the same time, and more specifically, the caller's area code + l The present invention relates to a method for liberalizing attendees in a teleconference system in which attendees can participate in an ongoing teleconference by dialing a participant number.

(Prior Art) In conventional teleconference services, the convenor who dials the number is determined by the number of 9. The PT teleconference was conducted by the convenor dialing the conveneee. If you want to add an invitee while this conference call is in progress, the convenor leaves the conference call, dials all the invitees, and confirms that the invitee has responded. Furthermore, a service instruction to start a meeting was given by dialing. By the above operation, it was possible to return to the telephone conference in progress, and it was also possible for additional invitees to participate in the telephone conference.

(Problem to be Solved by the Invention) However, in the conventional teleconferencing service, additional participants cannot freely participate in the conference, and the convenor cannot freely participate in the teleconference currently being held as described above. This is done by leaving your seat and operating a designated dial.
When calling additional invitees to participate, there is a drawback in that the current discussion must be interrupted until the calling is completed.

The object of the present invention is to provide a teleconference system in which participants can participate by dialing a predetermined number from the conference caller's side, rather than from the conference caller's side, without interrupting the entire conference being held. The objective is to provide a method for liberalizing the number of conveners.

(Means for Solving the Problems) In order to achieve the above object, a method for liberalizing invitees in a teleconference system according to the present invention includes a subscriber exchange that accommodates a teleconference convenor and invitees, and a subscriber exchange that In a teleconference system comprising a relay exchange that relays all the systems, and a teleconference device housed in the relay exchange,
When a subscriber who wishes to participate dials a specific number during a teleconference, the subscriber exchange and the relay exchange connect the subscriber and the teleconference device, and the teleconference device receives the incoming call. When the second dial tone is completely returned, and then the subscriber hears the second dial tone and dials the entire subscriber number of the convener.

The system is configured to send a teleconference service notification message to the convenor of the teleconference, and also to return all teleconference service messages to the subscriber.

According to such a configuration, the participants can freely participate in the teleconference from the middle of the teleconference.

(Actual flow side) Hereinafter, the present invention will be explained in more detail with reference to all the drawings.

FIG. 1 is a diagram showing a sequence when an invitee participates in an ongoing teleconference, and FIG. 2 is a diagram showing a relay system during a teleconference and when an invitee participates in a teleconference.

In FIG. 2, the invitee 2 and the convener 3 are currently conducting a teleconference, and these subscribers are communicating via the local exchange 4 and toll exchange 5, respectively.
Connected to 1fii6.

When invitee l participates in an ongoing teleconference, follow the teleconference participation sequence shown in FIG.

Subscriber (invitee) 1 is the area code of convener 3 + IXY2
Dial.

The local exchange 4b follows the received dial number and transfers the dial number to the toll exchange 5. The toll exchange 5 allows the teleconference device 6 to receive a call from the subscriber (invited party) 1 .

When the telephone conference device 6 detects that there is an incoming call, it
Dial tone (SDT) t-generated and sent to invitee 1.

By listening to 5DTy, the invitee L dials the subscriber number of the convener 3.

The teleconference device 6, which has received the participant's number, sends a teleconference service message to the convenor 3 via the toll exchange 5 and the local exchange 4a. On the other hand, a message acknowledging participation in the telephone conference is sent back to the invitee 1 via the toll exchange 5 and the local exchange 4b.

Thereafter, the invitee 1 will be able to participate in the ongoing teleconference.

(Effects of the Invention) As explained above, the present invention provides a means for the convenor to temporarily leave his/her seat and dial the dial fee of the convener as a means of inviting the conveners during the ML conversation. Rather than having the person participate in the conference, the invitee is configured to be able to participate in the ongoing teleconference by dialing the entire area code of the convener + IXY + subscriber number of the convener. Therefore, there is an effect that the convener can participate in the conference, and the convener can continue the entire teleconference without leaving his/her seat.
