Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic switching system, and is intended to automatically reserve a time for a conference call and notify the conference organizer.

Conventionally, when making a conference call using an automatic switchboard that has a conference call function, the caller hosting the conference call dials the calling number for all participants at the start time of the conference to invite the participants. was taken.

If the conference call trunk used for the conference call is busy at the time of the conference call, it is necessary to wait until the conference call is finished being used. Furthermore, if a meeting was scheduled to be held far in advance, the user might forget the date and time of the meeting, and the conference call function was often not fully utilized.

The present invention eliminates these drawbacks, and allows the conference call organizer to register the scheduled date and time of the conference in advance using a telephone in the memory of the automatic switchboard, and to set up the conference call trunk to be used for the conference call in advance. A reservation is made at a scheduled date and time, and after that, the conference call organizer is automatically called from the switchboard to encourage the conference call to be held. It was designed to allow meetings to be held.

An embodiment of the present invention will be described below with reference to the drawings.

The drawing is a block diagram showing a portion of an automatic switchboard relating to conference calls, which is an embodiment of the present invention.

1 in the figure is a telephone for the conference call organizer and participants;
2 is a conference call trunk for detecting incoming and outgoing calls of the telephone set 1 and for making calls with current service subscribers; 4 is a subscriber circuit 2;
5 is a part of the memory that stores the write and read data necessary for controlling the central control unit 4; 7 is a gold clock that notifies the central control unit 4 of the date and time.

Next, the operation when making a conference call using this automatic exchange will be explained.

The host of the conference call takes telephone 1 off-hook and first dials the conference call reservation number. This information is not transmitted to the central control unit 4 via the subscriber circuit 2 of the telephone 1.

The organizer then enters the number of the phone on which he or she will be holding the meeting,
and the date and time of the event. Similarly, this information is not transmitted to the central control section 4, but is registered in the memory section 6 from the central control section 4. The central control unit 4 constantly monitors the clock 7, and when the registered date and time arrives, if the conference call trunk 3 is not in use, the central control unit 4 reserves the use of the conference call trunk 3, and The entire subscriber circuit 2 has already been registered in the memory part 5. Organizer's phone 1
make a call to. When the usage status of the conference call trunk 3 is checked, if it is busy, the central control unit 4 does not issue a call instruction until it becomes free.

Further, when the called conference organizer takes off the telephone 1, the central control unit 4 is notified via the subscriber circuit 2. For this reason, the calling state is canceled, and an instruction is then given to the telephone network 6 to connect the subscriber circuit 2 of the conference organizer and the conference call trunk 3, and the conference call is notified to the subscriber circuit 2 of the conference organizer. be notified through. Thereafter, the conference organizer convenes the conference participants one after another, thereby establishing a connection to the conference call trunk 3 and making it possible to conduct a conference call.

As described above, according to the present invention, a conference call reservation can be made at any time from any telephone, and at the reserved date and time, a notification of the conference call is sent to the designated telephone in a state where the conference call can be made, thereby ensuring that And conference calls can be held efficiently.
