Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic connection system for conference calls, and particularly to an automatic connection system for conference calls in an automatic private branch exchange (hereinafter referred to as PABX).

[Conventional technology]

Traditionally, this type of conference call connection is made by the extension subscriber himself or herself who calls the conference, or by an attendant at the request of the extension subscriber, who connects multiple extension subscribers participating in the conference at the conference start time. [Problem to be solved by the invention] In the conventional conference telephone connection described above, the extension subscriber convening the conference or the operator of the attendant However, conference participants are called by dial at the conference start time, so the conference convenor has to remember the conference start time, and the extension subscribers participating in the conference are called as one subscriber. There is a drawback that it requires a troublesome operation and time to make calls by dialing one by one.

[Means for solving problems]

The automatic connection method for a conference call of the present invention includes registration in which conference call start time data input in advance from a conference call organizer's telephone and the telephone numbers of the conference call participants are registered in an automatic indoor switching device. means, a conversation telephone communication means capable of making calls between the participants, and a telephone line from the participant's telephone that automatically calls the participant's telephone at the start time of the conference call and responds to the call. and conference telephone connection control means for automatically connecting to conference telephone communication means.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram showing one embodiment of the present invention.

In FIG. 1, the connection method of the conference telephone in this embodiment is as follows: a conference convenor's telephone (hereinafter referred to as A) 111 and three conference callee telephones (hereinafter referred to as B, C, and X) 112, 113.
, 119, respectively, four line circuits (hereinafter referred to as LC) 211, 212, 213, and 219, an outgoing register (hereinafter referred to as ORT) 22 that can count and store dial information, and a A conference telephone communication device (hereinafter referred to as CFU) 23 that enables telephone calls, and an LC 211

Next, the operation of this embodiment will be explained using FIGS. 2 to 4.

First, a case will be described in which a designated time automatic connection conference call is registered, in which the start time of the conference call is designated and conference participants are automatically convened at the designated time.

In FIG. 2, LC2], 1 detects the transmission of Al 11 and notifies the CCU 24. The CCU 24 captures the 0RT 22 based on the call notification from the A 111 and closes the link A of the SW 21. When 0RT23 completes preparations to receive dial pulses, 0RT23 transmits dial tone to A111.
to notify the CCU 24 of completion of dial pulse reception preparation.

Hearing the dial tone, A111 dials a predetermined registration code requesting registration of an automatically connected conference call at a specified time, and then dials the specified time to start the conference call and the invited subscribers B, C, and X112. 113 and 11
9 dialing the subscriber number 9 These dialing information are counted and accumulated by the 0RT 22 and transmitted to the CCU 24 together with the calling party information at the designated time to start the conference call. C.C.
The U24 analyzes the information transmitted from the ○RT22, and registers and temporarily stores in the CFM26 the designated time information, the calling subscriber number, and the invited subscriber number necessary for controlling the designated time automatic connection conference call.

After completing all dialing, A111 put down the handset and
Waits to be called at the specified time. During this time, the CFC 25 monitors the CFM 26 at regular intervals and detects whether or not there is a conference call that is automatically connected at a specified time registered in the corresponding time period.

Next, the operation of calling the conference convener will be explained.

In FIG. 3, when the CFC 25 detects from the CFM 26 that there is a registration of an automatically connected conference call at a specified time in the relevant time zone, the CFC 25 first reads the convening subscriber number from the CFM 26, and the accommodating location information of the convened subscriber.

Based on these received information, CCU24 reserves link B between A111 and CFU2B, starts RG27, and connects L.
A read signal is sent out via C211. When A111 responds, link B is closed and A111 and CFU
23 is connected, and the calling operation to the conference convenor is completed.

Next, the operation of calling all the invitees and responding thereto will be explained.

In FIG. 4, CFC25 is connected to A via CCU24.
After confirming the connection between 111 and CFU23, CFM26
Read all invited subscriber numbers registered at the relevant time from , and read the invited subscriber numbers B, C, and
and 119 accommodation position information and the CFU 23 boat information for attendees are analyzed and transmitted to the CCU 24. CCU24
is B, C7Jc and X11 based on these received information.

RG27 is activated for X112, 113, and 119, and a calling signal is sent out all at once via LC212, 213, and 219. B.

By the responses of C and X112, 113 and 119, links C, D and E are closed respectively, and CFU23 and B, C and X112, 113 and 119 are connected, and as a result,
Conference calls are now possible, including A111.

〔Effect of the invention〕

As explained above, the present invention allows an extension subscriber hosting a conference call to register the conference start time and conference participating subscriber numbers in advance in the registration means of the automatic private branch exchange, so that the conference call can be started at the designated time. Since it is possible to automatically call conference participants and automatically connect to the conference phone call method after answering, the conference call organizer saves time and effort in calling operations, and eliminates the need to forget to convene a meeting. It has the effect of being able to
