Description

How to establish a conference call on a simple exchange

The present invention relates to the establishment of a conference call of a simple exchange, and in particular, a conference host designates all conference participants and automatically calls them at the same time, announces the start of a conference using a voice service device, and confirms whether or not the conference participants participate in the conference by answering the call. A method for establishing a conference call of a simple exchange which is provided to the presenter.

In order to establish a conference call in the conventional simple exchange, a method of establishing a call in the same way as a general call establishment method based on a two-way call state and using a method of adding participants by calling one participant to participate in the conference.

At this point, whenever a participant is added to the conference, participants who have already joined the conference and are on the call must be put on hold and wait for the final participant to participate. Called one by one to inform them of the meeting. In addition, the conference host cannot know when any participant drops the conference call while the conference call is in progress.

Then, the process of establishing a conference call in the conventional simple exchange will be briefly described as follows with reference to the flowchart of FIG. 1.

First, when the coordinator turns off the handset to make a call, the coordinator side detects an off hook (step T1) and generates a dial tone to provide to the coordinator (step T2).

Accordingly, when the conference presiding authority hears the corresponding dial tone and authorizes the calling number to call any of the participants of the conference to participate in the conference, the conference presiding party receives the corresponding calling number (step T3) and corresponds to the corresponding calling number. The meeting participant is called (step T4).

Then, the conference participant side recognizes the call from the conference chairperson (step T5) and creates a call ring and provides it to the conference participant (step T6), and the conference chairperson generates a callback tone to generate a ringback tone. It will be provided to the meeting chair (step T7).

Then, when the conference participant hears the call ring and turns off the handset, the conference participant side detects an off-hook (step T8) and transmits a call response signal of the response to the conference chair's call to the conference chairman ( In step T9), the conference participant side receives the corresponding call response signal (step T10), thereby forming a call path between the conference owner and the conference participant (step T11).

Thereafter, the conference host sends a guide message to guide the conference participant (step T12), and the conference participant receives the conference guide message (step T13), whereby the conference host has a function for the conference function. When the conference button, which is a button, is pressed, the conference chairman detects an input of the conference button (step T14) and generates a dial tone again and provides it to the conference chairman (step T15). Then, the conference participant side detects redial tone generation on the participant's side (step T16) and generates a pending tone to provide to the conference participant (step T17).

Accordingly, the conference chairman checks whether the conference chairman presses the conference button again to start the conference call (step T18).

If there is no re-entry of the corresponding conference button and the user presses another call number to call a new conference participant, the conference host side receives the corresponding other call number (step T19) and calls the conference participant corresponding to the other call number. The process is repeated from the fourth step T4.

On the other hand, if the re-entry of the corresponding meeting button is confirmed, all the meeting participant side also confirms that the meeting button re-entry of the meeting presiding party is performed (step T20), and then a call path is formed between the meeting presiding party and all meeting participants. The conference call is made (step T21).

However, in the conventional simple exchange, the conference call establishment method has the following problems. When the conference host calls the conference participants to establish the conference call, the conference participants are called one by one without specifying the call in advance. Participants must wait with the tone held until the conference call is initiated, and the chairperson of the conference must send the announcement to the conference participants repeatedly to inform them that the conference is in progress. The attendees did not know which participant ended the conference call because the status of the conference was not known.

As such, the conventional simple exchange method of establishing a conference call requires calling a conference participant one by one at the time of a conference call to notify the conference attendee, and the conference participant who is called to wait until the conference call starts, as well as the conference host during the conference call. There was a problem that the participation status of the meeting participants is unknown.

In order to solve the inconvenience described above, the present invention automatically calls the meeting host after all the meeting participants designate them before the call, and announces the start of the meeting using the voice service device, and all the meeting participants answer the meeting call. By providing the meeting owner with a way to know if they are present, there is no need to call a meeting participant at the time of the conference call to announce the participation, and the called meeting participant does not have to wait until the conference call starts. In addition, it is intended to enable the conference host to know the participants' participation status during the conference call.

It will be described below with reference to the accompanying drawings, Figure 2 is a block diagram showing a conferencing call establishment system of a simple switch according to an embodiment of the present invention, Figure 3 is a simplified switch according to an embodiment of the present invention 4 is a flowchart illustrating a method of establishing a conference call. FIG. 4 is a flowchart illustrating a process of designating a meeting participant in FIG. 3, and FIG. 5 is a process of calling a conference participant in FIG. FIG. 6 is a flowchart illustrating a process of performing a conference call guide function in FIG. 3, and FIG. 7 is a flowchart illustrating a process of performing a conference participant response function in FIG.

As illustrated in FIG. 2, the conference call establishment system of the simple exchange according to the embodiment of the present invention includes a conference presiding terminal 10, a simple exchange system 20, and a plurality of conference participation terminals 30-1 to. 30-N).

The conference presiding terminal 10 includes a plurality of flexible buttons, which are function buttons capable of specifying a corresponding function with a conference button which is a function button for a conference function and an LED related to a designated function.

The simple switching system 20 performs a conference call guide voice function for transmitting a pre-recorded conference call guide message by using a voice service device.

First, a method of establishing a conference call of a simple exchange according to an embodiment of the present invention will be briefly described with reference to the flowchart of FIG. 3 as follows.

In order to predetermine all conference participants who will join the conference through the conference host terminal 10, the conference host assigns a call number of the conference participant to each function button, for example, pressing the conference button, which is a function button for the conference function. Later, you can assign a function button to which the function is assigned with the LED associated with the function by pressing the floating button together with the extension or speed dial number of the conference participant. That is, a function of designating all conference participants in advance is performed (step S1).

Then, when the conference host presses the conference button to call all the designated conference participants through the conference host terminal 10, the conference host senses the input of the conference button and reads the call number for all the specified conference participants. After that, the LED of the floating button corresponding to the call number is automatically called while flashing. That is, a function of calling all the specified conference participants is performed (step S2).

Therefore, when each meeting participant hears a ringing call through each conference participation terminal 30-1 to 30 -N and picks up the handset, the simple switching system 20 uses a voice service device to provide a guide message for calling a conference. Inform each meeting participant through each conference participating terminal (30-1 to 30-N). That is, a function of transmitting a conference call guide message is performed to all the specified conference participants (step S3).

Then, each meeting participant listens to the conference call guidance message through each conference participation terminal 30-1 to 30-N and decides whether to participate in the conference, that is, whether to hold the handset or place the handset. . In other words, each designated participant is off-hook when the participant participates, and on-hook if not, and the designated part of the conference participant 10 is notified. A response function of all conference participants is performed (step S4).

Accordingly, the status of each conference participant is displayed on the LED of the floating button provided in the conference host terminal 10. For example, the LED blinks while all the conference participants are called and all the conference participants are designated. LEDs are turned on for the conference participant to join, and LEDs are turned off for the conference participant not to participate among all the conference participants specified above. That is, the function of displaying the status of all the specified conference participants (step S5).

Then, when the conference host presses the conference button of the conference host terminal 10 while checking the state of the LED, the conference host terminal confirms re-entry of the conference button on the conference host terminal 10 side and then enters each conference participating terminal 30. -1 ~ 30-N) to open all of the call path to the conference call. That is, the conference start function is performed between the conference owner and all conference participants who participated (step S6).

Next, referring to the flow chart of FIG. 4, the process of performing the meeting participant designation function of the first step S1 will be described in more detail.

When the conference host raises the handset to predetermine all the conference participants who will participate in the conference through the conference host terminal 10, confirms the off-hook of the conference host terminal 10 (step S1-1) The terminal 1 generates a dial tone and sends it to the conference chairman (step S1-2).

Accordingly, when the conference chairman presses the conference button after listening to the dial tone, the conference host terminal 10 confirms the input of the conference button (step S1-3), and the conference host all the parties to join the conference. When the floating button and the call number of the corresponding meeting participant are pressed to register the meeting participant, the conference presiding terminal 10 confirms the input of the corresponding floating button and the call number (step S1-4) and the corresponding meeting on the floating button. The call number for the participant is registered (step S1-5).

Then, the conference presiding terminal 10 notifies by generating a confirmation tone that the registration of the call number for the conference participant is valid (step S1-6).

Also, it is determined whether the conference host inputs a call number for another floating button and another meeting participant to register another meeting participant who will join the meeting. The call number registration of step 5 (S1-5) and the registration confirmation tone transmission of the first step 6-6 (S1-6) continue to be performed, and if the other floating button and call number are not input, the first step The process of performing the meeting participant designation function in step S1 ends all (steps S1-7).

Third, the process of performing the conference participant calling function of the second step S2 will be described in more detail with reference to the flowchart of FIG. 5.

When the meeting chairman presses the meeting button again to call all the meeting participants registered in the first step S1 through the meeting chair terminal 10, the meeting chair terminal 10 resets the meeting button. After confirming the input (step S2-1), the call number for all the conference participants registered in the first step S1 is automatically called (step S2-2).

In addition, the conference presiding terminal 10 notifies the conference presiding person that the call function is performed by blinking the LEDs of the flow buttons related to all the conference participants registered in the first step S1 (step S2-3). .

Fourth, the process of performing the conference call guide message transmission function of the third step S3 will be described in more detail with reference to the flowchart of FIG. 6.

Each meeting participation terminal 30-1 to 30-N confirms the re-entry of the meeting button on the conference presiding terminal 10 side (step S3-1), and generates a call ring and sends it to each meeting participant (step S3-2).

Accordingly, when each conference participant hears a ringing call through the conference participation terminals 30-1 to 30 -N and listens to the handset, the simple switching system 20 receives the conference participation terminals 30-1 to 30- After detecting the off-hook of N) (step S3-3), a guide message for calling a meeting previously stored using the voice service device is read (step S3-4), and each off-hook conference participating terminal ( 30-1 to 30-N) side (step S3-5).

Accordingly, each off-hook conference participation terminal 30-1 to 30-N receives the conference call guidance message (step S3-6) and informs each conference participant (step S3-7).

Fifth, a process of performing the conference participant response function of the fourth step S4 will be described in more detail with reference to the flowchart of FIG. 7.

Each meeting participant listens to the conference call guidance message through each conference joining terminal (30-1 to 30-N) and decides whether or not to join the meeting, i.e., if each conference participant wishes to join, they will be off-hook and not joined. In case of on-hook.

Therefore, at the same time as checking whether the respective conference participation terminals 30-1 to 30 -N are off-hook, the conference host terminal 10 also checks the conference participation terminals 30-1 to 30 -N. ) Is off-hook (step S4-1).

Accordingly, if the on-hook of the conference participation terminals 30-1 to 30 -N is confirmed, the LEDs of the floating buttons related to the corresponding on-hook conference participation terminals 30-1 to 30 -N are turned off. In this case, the conference attending terminal 30-1 to 30 -N notifies the conference host that the conference participation terminal 30-1 to 30 -N did not join the conference (step S4-2).

On the other hand, when the off-hooks of the conference participation terminals 30-1 to 30 -N are confirmed, the LEDs of the floating buttons related to the off-hook conference participation terminals 30-1 to 30 -N are turned on to correspond to the off-hooks. The meeting attending terminal 30-1 to 30 -N informs the meeting owner that the meeting is participating (step S4-3). Then, the off-hook conference participation terminals 30-1 to 30-N generate a pending tone and notify the conference participants (step S4-4).

Unlike the above-described technique, when a conference including the same conference participant is frequently held, a call number for the conference participant is stored in a database in advance to perform the conference participant designation function of the first step S1. The process of omitting a process may be omitted and the conference button input of the second step S2 may be immediately checked to call a conference participant stored in a corresponding database.

In addition, when the conference participation terminals 30-1 to 30 -N are provided with LCDs that can display texts, in the third step S3, texts can be converted into texts using the corresponding LCDs instead of the conference call guide voices. You can also guide.

As described above, according to the present invention, in the establishment of the conference call of the simple exchange, all the conference participants who will participate in the conference are designated in advance and then automatically called at the same time, and the conference call response is announced by using the voice service device or the text service device and the conference call response of all conference participants. As the LED of the floating button for, you can check the meeting participation status, simplifying the time and process of call establishment and easily checking the meeting participation status for meeting participants.
