Teleconferencing unit {TELE CONFERENCE APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a teleconferencing device, and more particularly, to a teleconferencing device that invites necessary persons to participate in a conference during a teleconference through a public switched telephone network (PSTN) and an internet network (IP network). It is about.

In general, a remote voice conferencing device is a device (hereinafter, referred to as a "conference telephone device") that allows a large number of geographically dispersed people to have a conference call as if they were gathered together in one place. It is common in the world to use the term 'conference call' or 'tele-conference'.

However, most conference telephone devices currently on the market connect only to a public switched telephone network (PSTN) or a voice over internet network (VoIP Network) to connect only to an internet network (IP network).

In practice, however, the actual meeting is usually conducted between the internal personnel connected to the IP network and the external personnel connected to the PSTN network.

Currently, although the teleconferencing device using voice over internet network (VoIP) has a standard specification defined, it is implemented by applying different standards according to each seller in actual implementation, so that devices having different standards are used. Many difficulties arise when working.

On the other hand, if you look at the general type of meeting using the teleconference device, many related departments attend the meeting because there may be questions about what the representative does not know during the meeting. There is a problem that only wastes time.

In addition, most conference telephone apparatuses presently have a problem in that internal conference participants hear and talk to external conference partners.

Therefore, the present invention has been created to solve the above-mentioned conventional problems, and during the teleconference through the Public Switched Telephone Network (PSTN) and the Internet (IP Network), the necessary personnel are invited every time The object is to provide a teleconferencing device that allows participation in a meeting.

In addition, the present invention does not attend the meeting in person, but waiting to participate in the meeting at any time, while performing their tasks, if necessary to participate in the meeting by receiving a request to participate, if not necessary time, Its purpose is to provide a teleconferencing device that saves money and enables efficient work.

In addition, an object of the present invention is to provide a teleconference device that can block in advance so that talks exchanged between participants in the internal conference is not transmitted to the external conference partner.

In order to achieve the above object, the present invention provides a teleconferencing device for enabling a meeting with a remote counterpart, comprising: a codec for connecting a voice call with a conference participant through an IP network or a wireless network; A selector for diverting the voice call to a headset or speaker / microphone path; A mixer for mixing all voice calls of the conference participants and outputting them to a speaker / microphone path; Each component is characterized in that it comprises a CPI for smooth voice call connection.

The present invention has a feature in that a hardware structure having an Internet phone and a PSTN gateway further includes a conference participation switching unit so that a person who is not necessarily required can call (invite) only when necessary to participate in a conference.

In addition, the present invention allows to select the Invite, Add, Stand-by, Close Connection mode during the meeting in the IP network so that the required number of people can participate in the meeting There is a characteristic.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is a block diagram showing the configuration of a teleconferencing device according to the present invention, in which a conversation can be made by an IP phone and a speaker / microphone 110, and with various conference participants who do not attend the conference directly. A codec 80 for connection and a selector 90 for switching from a headset path (stand-by state) to a speaker / microphone path (conference) by a control signal of the CPU. ), A mixer 100 that allows analog mixing of calls with all participants, and conference function, and a PSTN gateway 120 function.

The wireless interface unit 60 omitted in the above description serves to connect with a wireless terminal such as Bluetooth, and the LCD unit 40 outputs a guide message for a conference progress state or device operation, and the DSP 70. Denotes a channel for transmitting a voice packet, and the IP network interface unit 30 connects a user connected to the IP network.

The teleconferencing device configured as described above is connected to an end user device, such as a PC or an IP phone, to control the DSP determined by the control of the CPU 10. It is processed by one channel and a codec, and the selector 90 may select a multiple voice path through a headset, a speaker / microphone, and a PSTN gateway.

In the above configuration, the meeting participation switching unit 80 to 130 may invite users who are internally waiting for the meeting to participate in the meeting when necessary, and may be invited, add, stand-by, or terminate the connection. Four states of (Close Connection) can be selected.

Also, call setup, add call, stand-by, Four states of Close Connection can be selected.

In addition, an alarm is sent by ringing or blinking a cursor to notify a user who is in a waiting state to join a meeting.

As mentioned above, the method of joining a meeting through an alarm is that if each computer is only logged on when using the Internet messenger program, as long as it is waiting to join the meeting, it is necessary to chat with only the necessary people when necessary. If necessary, you will receive an alert so you can join the meeting.

The conference method by the teleconferencing device configured as described above can be largely divided into a conference involving an internal waiter connected to an IP network and a conference performed jointly with the PSTN and the IP network.

First of all, the meeting in the IP network invites a user who is in a waiting state to conduct a meeting. The meeting coordinator, according to the menu displayed on the LCD of the remote conference apparatus, may have a final event such as a PC or an Internet phone. After performing connection setup with a user terminal and passing voice packets through the intranet through one channel and codec of the DSP 70 through the IP network interface unit 30 and the CPU 10, the speaker You can join the meeting via the microphone 110.

Next, in order to add the required number of participants to the meeting during the meeting, the meeting host performs a connection setup with end users, such as PCs or Internet phones, who want to join the meeting, Voice packets pass through a channel and codec of the DSP 70 through the IP network interface unit 30 and the CPU 10, and then interrupt the ongoing meeting by dividing the internally necessary talks with the waiter with the headset 130. Do not become.

If the situation is only necessary between the conference host and the corresponding person, after the call with the headset terminates the connection with the waiter, and to join the ongoing conference, switch the current connection state from the headset to the speaker / microphone 110, The participants and the mixing unit 100 can be combined to continue the meeting.

Here, the meeting joining standby state refers to a state connected to the headset 130 through the selector 90, and when the meeting is not necessary for a certain time during the meeting with several meeting participants, the meeting is switched to the standby state. can do.

Of course, if you terminate the connection with the participant who no longer needs to participate in the meeting, you can disconnect manually or automatically.

Next, let's take a look at how to conduct the meeting jointly by connecting the PSTN and the IP network.

First, the conference coordinator performs call setup using VoIP and gateway to end users connected to the PSTN.

Accordingly, if the analog voice transmitted through the PSTN network is input through the PSTN gateway 120 through one channel of the codec and the DSP assigned to the call setup, the CPI may transmit the voice call through the gateway to one channel of the other DSP. The speaker / microphone is output through the and codec to join the conference.

For reference, in the present invention, one DSP and one codec are required to connect a call with participants in the IP network, but two DSP and two codecs per PSTN line are required for the PSTN network conference participants.

The teleconferencing device of the present invention can normally connect end-users such as PCs or Internet phones with two telephones connected to the PSTN network by basically two lines of PSTN through VoIP and gateway functions.

In other words, if you call set up the PSTN phone that you want to participate in the conference additionally according to the VoIP standard, analog voices passing through the PSTN network pass through the PSTN gateway, and the codec and DSP assigned to the call setup in the CPU When input through a channel, the CPU outputs the voice packet input through the gateway to the headset through one channel and codec of another DSP, so that once the conference is waiting to be held, the headset talks with the conference host separately to prevent an ongoing meeting. Do not

If the situation is only necessary with the conference host, the headset terminates the call immediately after the call with the headset, and calls the DSP channel and codec through the CPU to join the conference in progress. Instead, switch to speaker / microphone to mix through the mixer to continue the meeting.

Here, a conference over the Internet is like a conference over an intranet, except that it passes through a router or firewall when traversing the intranet and the Internet, and when there is no conference, an IP phone or PC on the intranet connects the remote conference unit to the PSTN gateway. You can use 1: 1 phone call.

Meanwhile, in the above embodiment, the meeting participation is a concept distinguished from attending the meeting.

Participation means attending a conference room with a teleconference device in person, and attending a conference means joining a conference by invitation only when necessary by PC or Internet phone.

Therefore, in the conventional case, in order to conduct a meeting with the counterpart in a remote place, the number of persons participating in the meeting must attend the conference room equipped with the teleconference device, but the present invention is only required for the required persons as shown in FIG. Participate in meetings and perform other tasks for the rest of the staff, and increase the efficiency of work by allowing them to attend meetings through PCs or Internet phones connected to wireless or IP networks only when necessary.

As described above, the teleconferencing device of the present invention is capable of meeting without passing through various PSTN lines and telephone companies, enables individual calls and calls in a stand-by state during a meeting, and enables a call with a wireless device.
