DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

1 is a block diagram showing a recording system according to the present invention. Referring to FIG. 1, the recording system 100 according to the present invention enables a service user to record a conversation with a counterpart connected via a wired communication network. The recording system 100 shown in FIG. 1 includes a computer and telephony integration (CTI) server 110, a first matching device 120, a second matching device 130, and a web server. 140. The user terminal 150 is connected to the wired communication network 160 via a telephone line (TPL). The computer integrated telephone server 110 is connected to the database 170, and the database 170 stores member management information and member call contents. The web server 140 is connected to the member management database 180, and the member management database 180 stores member management information and usage history of a user registered as a member.

The first matching device 120 is connected to a telephone line (TPL) and an internet network 200 used by a service user, respectively, and detects whether the telephone line (TPL) is used. When the service user is talking on the telephone line (TPL), the first matching device 120 converts the contents of the call in the analog format into the data in the TCP / IP format, and thus the converted data (that is, the call of the service user). Contents) are transmitted to the web server 140 via the Internet network 200. The data delivered to the web server 140 (ie, the content of the call of the service user) is stored as a file in the database 170 of the computer telephony integration server 110.

As shown in FIG. 2, the first matching device 120 includes a voltage detecting block 121, a switch block 122, and an analog-to-digital converter. It consists of a converter 123, a microcomputer 124, a setting switch block 125, a memory 126, and a TCP / IP conversion block 127. The voltage detection block 121 is connected to the telephone line TPL and detects a voltage change of the telephone line TPL. As is well known, the telephone line (TPL) has a voltage of about 50V normally and has a voltage of about 5V-10V during a call. The microcomputer 124 controls the switch block 122 in response to the detection signal of the voltage detection block 121. For example, when the voltage of the telephone line TPL is about 50V, the switch block 122 does not operate. That is, the telephone line TPL is electrically separated from the analog-to-digital converter 123. In contrast, when the voltage of the telephone line TPL is about 10 V, the switch block 122 electrically connects the telephone line TPL to the analog-to-digital converter 123.

The call content transmitted through the telephone line (TPL) will be transmitted to the other party through the wired communication network (160). At the same time, the analog-to-digital converter 123 converts the call content in the analog format into data in the digital format. The microcomputer 124 accepts the data converted by the analog-digital converter 123 and converts the input data into serial data. The serial data thus converted is output to the TCP / IP conversion block 127. . The TCP / IP conversion block 127 transmits serial data (that is, call content) transmitted from the microcomputer 124 to the web server 140 through the internet network 200. The setting switch 125 is connected to the microcomputer 124 and is for inputting user's connection environment information (for example, telephone line number, IP address, etc.). The connection environment information so input will be stored in the memory 126 via the microcomputer 124.

Although FIG. 2 shows a first matching device 120 associated with only one telephone line (TPL), the configuration of the first matching device associated with a plurality of telephone lines includes a voltage detection block, a switch block, and an analog-digital device. Except for the transducer, it is similar to that shown in FIG. That is, referring to FIG. 10, the voltage detection block 121 ′ detects a voltage change on the plurality of telephone lines, respectively, and the switch block 122 ′ is composed of a plurality of switches respectively corresponding to the plurality of telephone lines. Will be constructed. The switches of the switch block 122 'will be controlled by the microcomputer 124' according to the detection result of the voltage detection block 121 '. The analog-to-digital converter 123 'also includes a plurality of analog-to-digital converters respectively corresponding to the plurality of telephone lines, and each analog-to-digital converter operates substantially the same as that shown in FIG. The telephone lines may be directly connected to the user terminals respectively or connected to the user terminals via a private branch exchange (PBX).

Referring back to FIG. 1, the second matching device 130 is connected to the telephone line TPL and to the leased line EXL, and the leased line EXL is connected to the computer telephone integration server through the wired communication network 160. 110). The second matching device 130 detects whether the telephone line TPL is used, and connects the telephone line TPL and the dedicated line EXL with each other according to the detection result. As shown in FIG. 3, the second matching device 130 includes a voltage detection block 131 and a switch block 132. The voltage detection block 131 controls the switch block 132 by detecting a voltage change on the telephone line TPL or a voltage change of a signal output from the microphone device 190. The switch block 132 selectively connects the input terminal TPL or 190 and the dedicated line EXL under the control of the voltage detection block 131. Here, when the second matching device 130 is connected to a plurality of telephone lines, as shown in FIG. 10, a voltage detection block 131 ′ and a switch block 132 ′ corresponding to each telephone line are required. Do.

The recording system 100 according to the present invention further includes an audio microphone device 190, as shown in FIG. 1, wherein the audio microphone device 190 communicates between a counterpart and a service user. The content is passed to the second matching device 130. The second matching device 130 transmits the dialogue content output from the audio microphone device 190 to the dedicated line EXL. The conversation contents transmitted to the leased line (EXL) will be transmitted to the computer telephone integration server 110 through the wired communication network 160. Although not shown in the drawings, it is apparent that the audio microphone device 190 may be connected to the web server 140 via the first matching device 120 and the Internet network 200.

The recording system having the configuration as described above provides the following recording (or recording) function. First, when the service user calls the other party and makes a call, the recording system records the call content between the service user and the other party and stores the recorded call content in the database 170. Secondly, when the service user calls the other party and makes a call or the other party calls the service user and makes a call, the recording system records the contents of the call between the service user and the other party through an internet network or a dedicated line. The call details are stored in the database 170. Third, when the service user conducts a meeting in a place such as a conference room, the recording system records the conversation contents through a leased line and stores the recorded call contents in the database 170. In addition to the recording function, it is obvious that various recording functions may exist. This will be explained in detail later.

4 is a flowchart illustrating a recording process according to the present invention when a service user makes or receives a call. For convenience of explanation, the recording process according to the present invention will be described assuming that the service user calls the other party. However, if the other party calls the service user, the recording process will be performed in the same way. A person who wants to use the recording system joins as a member through the Internet or a wired communication network. Such members are hereinafter referred to as "service users". First, the service user makes a call to the other party through the wired communication network 160 using the user terminal 150 (S100).

As is well known, companies that operate wired networks provide services that allow multiple people to talk simultaneously, and how to use those services is different for each company. For example, according to the multi-party service provided by KT, the subscriber calls the first party, talks, and then presses and releases the hook switch once and then calls the second party again. At this time, the standby sound is transmitted to the first counterpart. When the telephone call is made with the second party, the subscriber once again presses and releases the hook switch. In this way, you can talk to several parties simultaneously. In this embodiment, assume that a service user is subscribed to a service provided by a company operating a wired communication network.

In a next step (S110), the service user places the other party in a standby state by using a multi-party service provided by a communication company and then calls the computer telephone integration server 110. When connected to the computer integrated phone server 110, a guide broadcast informing the usage method is transmitted (S120). Next, the computer telephone integration server 110 checks whether or not the person who accesses the server is registered as a member (S130), and selects one of the recording function, the listening function, and the ending function by the service user. Determine (S140). When the service user selects the end function, the connection with the computer integrated telephone server 110 is terminated without the recording / listening process. That is, when the service user selects the end function, the service user talks to the other party without recording.

When the service user selects the recording function, the computer-telephone integrated server 110 starts recording the contents of the call between the service user and the counterpart (S150). That is, if the service user presses and releases the hook switch once after selecting the recording function, the computer-telephone integrated server 110 starts recording the call content of the service user and the other party. The service user ends the telephone call with the other party. In operation S160, the computer-telephone integration server 110 generates a recorded content as a file and stores the recorded content in a database. When the service user wants to listen to the current or previously recorded conversation contents in step S140, the computer phone call server 110 listens to the recorded conversation contents to the service user, and the use of the service is terminated (S170).

As can be seen from the above description, the service user can record the contents of the conversation with the counterpart without providing a separate recording device. The service user can listen to the recorded content through the method described above. In addition, since the recorded contents are stored in a file, the service user can access the web server 140 and download the file of the recorded contents from the web server 140. The file stored in the recording system according to the present invention will be created to have one of various formats (for example, wav, mp3, etc.), and this technique is obvious to those who have acquired the general knowledge in this field. Do. In addition, when a service user calls the other party using a landline or mobile phone in the house, or calls the other party using a public telephone from outside, or the other party has either a landline or mobile phone, When calling a service user, the call content between the service user and the counterpart may be recorded in any call path through the above-described process.

5 is a flowchart illustrating the recording process of the present invention in which the contents of the call of the service user are unconditionally recorded when the service user makes or receives a call. When the telephone line of the service user is connected to the second matching device 130, the call content between the service user and the other party is always recorded regardless of the intention of the service user or the counterpart. More specifically, it is as follows. When the service user makes a call to the other party or a call is received from the other party (S200), the second matching device 130 detects a voltage change on the telephone line TRL to establish a telephone line TRL and a dedicated line EXL. It is connected to each other (S210, S220).

Since the dedicated line EXL is connected to the computer-telephone integrated server 110 via the wired communication network 160, the call content of the service user is automatically stored in the database 170 through the computer-telephone integrated server 110. (S230). The computer telephone integration server 110 determines whether the terminal of the service user is in the off hook state (S230). If the service user's terminal 150 is in the off-hook state, the computer telephone integration server 110 continuously records the conversation between the service user and the counterpart. If the terminal 150 of the service user is not in the off-hook state, the computer integrated telephone server 110 generates a file containing the recorded conversation contents and stores the file in the database (S250).

The recording system of the present invention can record the service user talking to the other party in the conference room according to the flowchart shown in FIG. When the audio microphone device 190 of the service user is connected to the second matching device 130, the call content between the service user and the counterpart is automatically recorded through the recording system of the present invention. More specifically, it is as follows. When the service user talks with the other party at an arbitrary place (S300), the second matching device 130 detects a voltage change of the output signal of the audio microphone device 190 to detect the voltage of the audio microphone device 190 and the dedicated line (EXL). ) Are connected to each other (S310, S320).

Since the dedicated line EXL is connected to the computer-telephone integrated server 110 via the wired communication network 160, the call content of the service user is automatically stored in the database 170 through the computer-telephone integrated server 110. (S330). The computer telephone integration server 110 detects whether there is an output from the audio microphone device 190 (S340). If there is an output from the audio microphone device 190, the computer telephone integration server 110 continues to record the conversation between the service user and the counterpart. If there is no output from the audio microphone device 190, the computer integrated phone server 110 generates and stores a file containing the recorded conversation content (S350).

7 is a flowchart illustrating another recording process of the present invention in which the contents of the call of the service user are unconditionally recorded when the service user makes or receives a call. When the telephone line of the service user is connected to the first matching device 120, the content of the call between the service user and the other party is independent of the intention of the service user or the other party, and the service user calls the other party or the other party is the service user. It is always recorded when you call. More specifically, it is as follows. When the service user calls the other party (S400), the first matching device 120 detects a voltage change on the telephone line (TRL) and connects the telephone line (TRL) and the Internet network 200 to each other (S410, S420). ).

As described above, the voice signal on the telephone line (TRL) is converted into serial data in TCP / IP format through the first matching device 120. The converted data is transmitted to the web server 140 through the internet network 200 in real time. The web server 140 stores the data of the contents of the call transmitted in real time in the database 170 through the computer dial-up server 110 (S430, S440, S450). That is, the contents of the call between the service user and the counterpart are recorded. The computer telephone integration server 110 determines whether the terminal of the service user is in the off hook state (S460). If the service user's terminal 150 is in the off-hook state, the computer telephone integration server 110 continuously records the conversation between the service user and the counterpart. If the terminal 150 of the service user is not in the off-hook state, the computer integrated telephone server 110 generates and stores a file including the recorded conversation contents (S470).

8 is a flowchart illustrating a recording process of the present invention when a non-member user wants to record a conversation with the counterpart. First, a person who wants to use a recording service according to the recording system of the present invention (for example, a person who is subscribed to a multi-party call service provided by a telecommunication company) uses a wired / wireless phone to connect to the computer phone integrated server 110. The telephone is connected to the computer telephone call server 110 (S500). The computer phone integration server 110 sends a guide broadcast informing the user of how to use the service (S510). For example, the content informing the conference call method, the charging method, the talk time, and the like will be broadcast. The user calls the other party after listening to the announcement (520). At this time, the computer phone call server 110 is in a call waiting state. When the connection with the other party is completed and the user presses and releases the hook switch once, the conversation contents between the user and the other party are stored in the computer phone call server 110 (S530).

When the call with the other party is terminated (S540), the computer integrated telephone server 110 determines which one the user has selected after sending out a guide broadcast informing the user of the listening function and the storing function (S550). If the user selects the save function, the recorded conversation contents are saved as a file (S560). Thereafter, the computer integrated telephone server 110 terminates the recording service after receiving the ID and password from the user. The user can download and listen to the recorded file through the web server. If the user selects the listening function, the computer integrated telephone server 110 tells the user a part of the recorded conversation contents and proceeds to step S560.

9 is a flowchart illustrating another recording process of the present invention when a non-member user wants to record a conversation with the other party. First, a person who wants to use a recording service according to the recording system of the present invention makes a call to the computer telephone integration server 110 by using a wired / wireless telephone and accesses the computer telephone call server 110 (S600). Computer integrated telephone server 110 outputs a message to enter the contact number of the other party (S610). When the user inputs the contact number of the counterpart (S620), the computer phone call server 110 calls the counterpart using the entered contact number (S630).

Simultaneously with the user talking to the other party through the computer telephone integration server 110, the computer telephone integration server 110 starts storing the contents of the conversation between the user and the other party (S640). When the call with the other party is terminated (S650), the computer integrated telephone server 110 sends out a guide broadcast notifying the listening function and the storage function to the user and determines which one the user has selected (S660). If the user selects the save function, the recorded conversation contents are saved as a file (S670). Thereafter, the computer integrated telephone server 110 terminates the recording service after receiving the ID and password from the user. The user can download and listen to the recorded file through the web server. If the user selects the listening function, the computer integrated telephone server 110 tells the user a part of the recorded conversation contents and proceeds to step S670.

11 is a block diagram illustrating a recording system according to another exemplary embodiment of the present invention. Referring to FIG. 11, a recording system 200 according to the present invention includes a computer telephone integration server 210, a database 220, and an interface device 230. The interface device 230 is connected between the terminal 240 of the service user and the wired communication network 240, and the database 220 is connected to the computer telephone integration server 210. The interface device 230 allows a service user to record a conversation with a counterpart using a multiparty call service provided by a communication company without operating a hook switch.

As shown in FIG. 11, the interface device 230 includes a DTMF detector 310, a relay 320, and a microcomputer 330. The DTMF detector 310 is connected to a telephone line and detects a specific dual tone multifrequency (DTMF) signal transmitted through the telephone line. The relay 320 is connected in the middle of the telephone line and is controlled by the microcomputer 330. The microcomputer 330 controls the relay 320 according to the detection result of the DTMF detector 310. For example, when a specific DTMF signal is detected, the microcomputer 330 switches off the relay 320 for about one second. That is, the call path of the telephone line is disconnected for about 1 second, and then formed again. This leaves the hook switch on hook for about 1 second. Here, the specific DTMF signal indicates, for example, a DTMF signal corresponding to the special key "#".

The recording system 200 according to the present invention allows a service user to store contents of a call with a counterpart using a home wireless telephone. More specifically, it is as follows. When the service user makes a call to the other party or receives a call from the other party using the wireless telephone, the contents of the call may be stored. For convenience, assume that a service user calls a party using a home wireless telephone.

The service user calls the other party by dialing the other party's telephone number. At this time, the DTMF detector 310 of the interface device 310 detects the DTMF signal on the telephone line. Since the detected DTMF signal is not a specific DTMF signal, the relay 320 remains switched on. When the service user is connected with the other party, the service user continuously inputs a specific key twice. DTMF detector 310 detects DTMF signals on the telephone line. Since the detected DTMF signal is a specific DTMF signal, the microcomputer 330 switches off the relay 320 for about 1 second in response to the output of the DTMF detector 310. This has the same effect as pressing and releasing the hook switch once. That is, the wait signal is transmitted to the other party through the wired communication network 250.

At this time, the service user dials the computer integrated telephone server 210 and again inputs a specific key twice in succession. DTMF detector 310 detects DTMF signals on the telephone line. Since the detected DTMF signal is a specific DTMF signal, the microcomputer 330 switches off the relay 320 for about 1 second in response to the output of the DTMF detector 310. Through this process, the contents of the call between the service user and the counterpart are automatically recorded through the computer phone integrated server 210. Recorded conversations can be downloaded via a web server or listened back through a computer phone integration server.

If the service user uses a cordless phone, the cordless phone does not have a hook switch function. Nevertheless, the recording system according to the present invention allows the service user to record the contents of the call with the counterpart even when using the terminal without the hook switch function. This situation may also exist in the case of using a private exchange. That is, as shown in FIG. 12, when the terminal of the service user is connected to the public telephone network (PSTN) through the private exchange, the conversation contents with the other party can be recorded by using the interface device 430 of the present invention. . This means that by using a recording service provided by the recording system according to the present invention without having to establish a separate recording system, it is possible to easily and inexpensively record a conversation with the other party. The interface device 430 of FIG. 12 is configured substantially the same as that of FIG. 11, and a description thereof is therefore omitted.

In the above, the configuration and operation of the circuit according to the present invention has been shown in accordance with the above description and drawings, but this is only an example, and various changes and modifications can be made without departing from the spirit and scope of the present invention. Of course. Although a recording system and a recording method using a wired communication network such as a public telephone network have been described, it is obvious that the recording system and the recording method of the present invention can be applied to a wireless communication network.

As described above, the service user can record the contents of the conversation with the counterpart without providing a separate recording device. The service user can listen to the recorded content through the above-described process. In addition, since the recorded content is stored as a file, the service user can connect to the web server and download the file of the recorded content from the web server. In addition, when a service user calls the other party using a landline or mobile phone in the house, or calls the other party using a public telephone from outside, or the other party has either a landline or mobile phone, When calling the service user, the call content between the service user and the counterpart may be recorded in any call path.
