The present invention relates to a multi-party call, and to a multi-party call method using a portable personal multi-party call that handles 5 or more multi-party calls on the user's side, regardless of whether an additional PSTN phone or an Internet phone is provided. .

In general, in order to make a multi-party call, it was possible to use a special key phone device that supports the multi-party call function in hardware / software or use an MCU device that supports the multi-party call in the telephone company's server. In other words, if you request a conference call by subscribing to a telecommunications company, you can connect with a plurality of phone numbers you want to call through the expensive MCU equipment that supports the conference call from the server of the carrier and then conference with the person who applied for the conference call. It is a concept to make a call, and a telephone call from an outside line simultaneously talks with a plurality of telephones connected to an extension through a special key phone device or exchange equipment (P (A) BX) that supports a multi-party call function. Although the multi-party call is supported by the server of the telecommunication company, there are no regional restrictions among the multi-party callers. Unlike the former concept of multi-currency, it is a partial / constrained multi-currency, not a true one.

In addition, users who use the Internet phone in the Internet phone network can only use the expensive MCU equipment that supports the multi-party call function in the server of the communication company.In this case, as the number of multi-party calls increases, the amount of data transmitted increases the quality of the voice or video call. It is not possible to guarantee the stability of the system, and there is a problem of paying an extra expensive surcharge for multi-currency.

2 is an example of a configuration of processing a multi-party call (eg, a 4-way call) through an MCU device connected to a gateway of an Internet phone station when using a conventional Internet phone network. The gateway of an Internet phone station must support a multi-call service. do. In addition, as the number of multi-party callers increases, there is a limitation that the number of callers is limited to about 3 or 4 people due to the instability of the network, which is degraded due to the increase of the data transmission.

Figure 3 shows a configuration of processing a multi-party call through the MCU equipment connected to the communication telephone station when using a conventional PSTN telephone network, for example, A calls the communication company to make a multi-party call with B, C, D If you apply, the telecommunications company connects B, C, and D by telephone and then makes a multi-party call with A. In other words, it is inconvenient to apply to a telecommunication company and go through a separate procedure that can be connected from the corresponding telecommunication telephone station.

Figure 4 is a configuration of processing a multi-party call with a plurality of telephones connected to the extension of the call from the outside through a special key phone device or exchange equipment (P (A) BX) granted a conventional multi-party call function, for example For example, when an outside A makes a call to a company that has a keyphone device or exchange equipment, he or she can make a simultaneous conference call with B, C, D, E telephones connected to the keyphone device or exchange equipment by extension. Will be. This is a limited multi-party implementation, with only one call coming from the outside with the extension phones in the office. If B, C, D, and E are outside the office, they will not be able to participate in the conference. It is not possible with a regular key phone device or exchange device, but only with an expensive special key phone device or exchange device programmed to make a multi-party call with the telephones connected to the station.

The present invention has been made to solve the above-mentioned problems, and whether the PSTN general telephone network or the Internet network, basically to realize a true multi-party call expensive special MCU equipment that supports the multi-party call connected to the telephone company of the communication company Only through the Internet phone, especially in case of Internet phone, additionally, the user's phone can be an Internet phone terminal with the ability to support a multi-party call. Even in the case of limited conferencing, it is possible only through expensive special phone equipment or exchange equipment with a built-in conferencing function.In the case of Internet telephony, as the number of conversing parties increases, data quality increases and the call quality becomes unstable. Have any of the above-described additions It is an object of the present invention to enable a multi-party call by only connecting to handset connection jacks of general telephones that do not have built-in five or more special functions to talk to the personal multi-party caller without equipment or device or procedure.

As shown in the block diagram of the personal conference handset according to the present invention of FIG. 1, the personal conference handset 1) is a "telephone transmission / transmitter" which serves to connect the handset connector of several telephones and the input terminal of the multiparty telephone. 2) "Audio Switch Controller" which blocks or connects audio signals from multiple phones, 3) "Audio Switch Controller" which controls audio switch, 4) Multiple phones "Audio Switch Controller display part" which indicates the blocking / connection status of the audio signal from the telephones and blocks or connects the audio signal of the telephone, respectively. 5) Audio signals input from several telephones are input to the microphone of the other telephone. "Audio splitter part", which sends audio signal to the part so that many people can talk to each other. "Audio power amplifier part" which amplifies the audio signal inputted from the audio signal and outputs it to the speaker. 7) Microphone sends the audio signal to the microphone input part of several phones so that they can talk with each other. Microphone input splitter section.

The personal multi-party call is directly connected to a general PSTN telephone or a handset connection terminal of an Internet telephone.

In addition, a handset receiver, a headset connector, a microphone and a speaker connector, etc., which use telephone handsets, are separately provided so that various handsets can be selectively adopted. You can also connect a recording device to record the conference.

In addition, the main board of a plurality of telephones connected to a personal conference call for a conference call may be integrated into the personal conference phone, thereby making it easier to operate the integrated personal conference call combining the phones and the conference call device. .

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

As shown in Fig. 5, if a person A wants to make a five-way call, he places an Internet phone on his desk and connects all of them to an "Internet Router" or "Hub" connected by an Internet LAN, respectively. You can make or receive After connecting to the personal conference call according to the present invention through the connecting handset terminals of the five telephones, make a call to B by the first telephone, C to the second telephone, D to the third telephone, and 4 When you call E on Phone 5 and call F on Phone 5, all of the six parties A, B, C, D, E, and F will conference through this personal conference. A is a multi-party call with 5 external B, C, D, E, and F through a handset connected to a personal conference. Of course, B, C, D, E, and F can talk to each other.

If the telephone connected to the personal conference call is a voice internet phone that supports voice only, the voice conference call becomes a voice conference call.

FIG. 6 is similar to the case of FIG. 5, when a person A wants to make a simultaneous call with five outside B, C, D, E, and F, general telephones 1, 2, 3, With the 4th and 5th telephones, the telephones are connected to general keyphone equipment or exchange equipment connected to 5 or more trunk lines by extension, and the 5 telephone handset receivers are connected to the personal telephone according to the present invention. After each direct connection, if you make a phone call to 5 external B, C, D, E, and F users with each of these 5 phones, all 6 of A, B, C, D, E, and F will make a conference call. .

If the telephone connected to the personal conference call is an Internet phone, the conference call is also made even if the user makes a call using a regular PSTN network phone instead of an external Internet phone. Conversely, if you connect a regular PSTN phone with a personal conference phone and make a phone call to an external Internet phone, the conference becomes a conference call. That is, it does not matter whether the telephone connected to the personal conference call is an Internet phone or a general PSTN phone, and it does not matter whether the external phone connected for the conference call is an Internet phone, a general phone or a mobile phone.

In this way, each phone is a one-to-one call on the communication network, but by using a personal conference call, the user can simultaneously make a terminal call with up to the number of connected phones. Call quality is like a one-to-one call without the problem of instability, and multilateral calls are made to anyone outside. In particular, in the video call, the stability of the video call quality is further secured. Of course, if you have 10 phones, you can make a 10-character call without any problem.

As described above, the present invention is independent of the server connected to the telephone company MCU equipment of the telecommunications company, anytime and anywhere independent of the user who wants to make a multi-party call without expensive special keyphone equipment or exchange equipment with anyone outside Simultaneous multi-party calls can be made at the same time, and as a portable multi-party caller rather than fixed expensive equipment, it is easy to move and install, and it is convenient to use. Since it is a multi-party call, it is possible to simultaneously and multi-party call more than 10 people without degrading the call quality due to the problem of the amount of transmitted data, which ensures the stability of call quality and economical burden because it does not use expensive special equipment. Also significantly reduce costs in terms of economics There is.
