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

1 is a block diagram showing a telephone dial tone conversion system according to a preferred embodiment of the present invention. As shown in FIG. 1, a telephone tone conversion system according to a preferred embodiment of the present invention includes a user terminal 100, a tone converter 200, a base station 300, and an ARS server 400. It consists of). The user terminal 100 may be a mobile terminal, a general telephone or a public telephone used in a home or office, and a wired / wireless internet function may be added to the telephone. When the user terminal 100 has an internet function, the ARS server 400 may be an internet server 500 as shown in FIG. 4. In addition, the user terminal 100 and the tone converter 200 may be preferably integrally formed.

The user terminal 100, DTMF (Dual Tone Multi-), the telephone number and other information of the receiving terminal (not shown) or the ARS server 400 to call through the input of the keypad (not shown) A dialing unit 160 which transmits a signal to a base station 300 in the form of a frequency signal or a dialing packet, a telephone circuit unit 140 including handset and control function, and an input through the keypad. It has a display unit 120 for outputting the character information or video information.

The tone converter 200 includes a vocoder 210 for analyzing or reconstructing a voice, a flash memory 220 that is a nonvolatile memory, a voice, and a specific tone, for example. For example, a tone / voice detector 230 capable of identifying a ringback tone, a busy tone, a network busy tone, and the like, and a counter storage unit 240 are provided.

In addition, the vocoder 210 converts the DTMF detector 212 for detecting a DTMF signal between the ARS server 400 and the user terminal 100, and converts an analog voice into a digital signal, It consists of an encoder 214 which converts the signal of the signal into an analog voice.

The flash memory 220 includes a DTMF activation program 222 for activating the DTMF signal detection mode, a control program 224 for controlling all components of the tone converter 200, and an advertisement, music, message or English conversation. And a sound source / video storage unit 226 for storing a sound source and / or a video.

In addition, the counter storage unit 240 is a call path between the receiving side and the calling side when the sound source and / or video including the advertisement, music, message or English conversation stored in the flash memory 220 is an advertisement It has counter information which increases as its value is formed. That is, the counter storage unit 240 increases the counter value after checking whether the advertisement is selected and the normal call is made by the control program 224 in the flash memory 220.

The tone / voice detector 230 distinguishes and detects a person's voice or a tone of a telephone transmitted from an exchange. Looking at the function, the tone detection is basically a ringback tone signal transmitted from an exchange, It is determined whether or not the telephone tone signal is based on a signal transmitted previously such as a busy tone signal, a hook-off signal, and a busy tone signal. In addition, as an additional judgment method, it is used in parallel with the signal detection as a method for detecting a difference between a telephone tone and a voice such as a ringback tone by software. The software method uses a voice tone coded linear prediction (QCELP) and / or an enhanced variable rate coder (EVRC), which is a type of cellular phone service, used for telephone tone and / or voice packets in a CDMA system. The vocoder 210, which is a change / compression algorithm, is coded into a packet. The telephone tone and / or voice packet coded by the vocoder and transmitted from the base station 300 is composed of a vector quantization value, a pitch parameter, and a format parameter. Through the normal decoding process of about 160 PCM samples can be obtained. In case of tone, energy is concentrated in a specific frequency group, and thus it can be distinguished from voice. In addition, speech and tone can be identified by approximating the frequency component of the received packet. In addition, since the ringback tone signal and the busy tone signal used in the telephone are repeated with a specific interruption ratio, the interruption ratio may be checked and applied to the detection of voice and tone auxiliary. For example, in the national formal approval tone specification table, the ringback tone signal has ON time of 1 second and the OFF time of 2 seconds, and the line busy tone signal, which is a participant busy signal, has ON / OFF time of 0.5 seconds each. In the case of trunk busy signal, which is a trunk line runaway signal, it has an ON time of 0.3 seconds and an OFF time of 0.2 seconds. At this time, the predetermined sound source is transmitted to the speaker during the time determined as ringback tone, and if it is determined that the ringback tone is not, the stored sound source is stopped and normal transmission is performed.

The ARS server 400 is a general well-known automatic voice response system, which has a sound source database unit 410 having a sound source such as advertisement, music, message or English conversation, and a member having member information of the user as a member. It has an information database unit 420. In addition, when the ARS server 400 becomes the Internet server 500, the Internet server 500 may be a publicly known Internet server, a sound source including advertising, music, messages or English conversation, and the like. And / or a sound source / video database unit 510 having a video and a member information database unit 520 having information of a member having the user as a member. Accordingly, a user of the user terminal 100 registered as a member of the ARS server 400 or the Internet server 500 replaces a ringback tone signal, a busy signal, or a network busy signal with an advertisement, music, message or English. When accessing the ARS server 400 or the Internet server 500 to use a sound source and / or a video including a conversation, the user checks the user's information as a member and the user terminal 100 wants the user. It plays a role of transmitting sound source and / or video. Member information stored in the member information database unit 420, 520 is basically the general information of the member, such as the member's telephone number, social security number, address, password, and the member is the ARS server 400 or the Internet server 500 It has information about the history of the sound source and / or video used to access to and the counter value information for listening to the advertisement of the user when the sound source and / or video is an advertisement.

2 is a flowchart illustrating a method of storing a sound source including an advertisement, music, a message, or an English conversation in the user terminal 100 in place of a telephone dial tone. First, a method of storing a sound source and / or a video in the user terminal 100 will be described. As shown in FIG. 2, when a call path is formed with the ARS server 400 and the user terminal 100 by the ARS server 400 or by the user terminal 100 (S1), the ring tone The control program 224 in the flash memory 220 of the converter 200 executes the DTMF activation program 222 to activate the DTMF detection mode of the DTMF detector 212. Therefore, the ARS server 400 and the user terminal 100 can communicate with each other through a DTMF command code. The ARS server 400 exports a message and a sample sound source to select a sound source, that is, advertisement, music, message, or English conversation, which the user wants to store with a predetermined DTMF command code, and in response, the user The DTMF command code for selecting one of sound sources, that is, advertisements, music, messages, or English conversations, which are desired to be stored through the keypad of the dialing unit 160 in the user terminal 100, is transmitted (S2). In response, the ARS server 400 transmits the DTMF command code indicating the start of recording of the selected sound source to the user terminal 100. After the recording is completed, the DTRS command code ends the recording of the selected sound source. Once transmitted, the selected sound source is stored in the sound source / video storage unit 226 of the signal converter 200 (S3).

At this time, the counter information storage unit 240 stored in the EEPROM in the tone converter 200 having the number of advertisements that the user listens to transmits the counter information request DTMF command of the ARS server 400 simultaneously with the transmission of the selected sound source. The code is transmitted from the user terminal 100 to the ARS server 400 and stored in the member information database unit 420. After that, the counter storage unit 240 is initialized (S5).

The DTMF command code may be implemented in various ways. For example, the DTMF command code may be "1, 2, 3, 4, 5, 6, 7, 8, 9, 0, #, *" or the like, or a frequency combination may be used. In other words, when the DTMF command code of the advertisement sound source selection request of the ARS server 400 is "# 1", "* 1" may be used as the response DTMF command code of the user terminal 100. In addition, when the DTMF command code of the music, message, or English conversation selection request of the ARS server 400 is "# 2", "* 2" may be used as the response DTMF command code of the user terminal 100. DTMF command codes indicating the start and end of the storage of the selected sound source of the ARS server 400 may be "# 3" and "# 4", respectively, wherein the user terminal 100 through the DTMF command code "# 4" It can be seen that the storing of the selected sound source is finished. The DTMF command code indicating the counter information request of the ARS server 400 may be "# *", and the response DTMF command code of the user terminal 100 may be "* # XXX". At this time, "XXX" is three-digit counter information, and the notation is decimal. For example, if the counter information is "1", it is "001" and if it is "100", it is "100". The data structure in which the selected sound source is transmitted has a form of "Flag1 (DTMF1) + selected sound source + Flag2 (DTMF2)". Therefore, when the user terminal 100 detects Flag1 (DTMF1), the signal sound converter 200 The storage of the selected sound source is started in the sound source / video storage unit 226 in the flash memory 220, and when the flag 2 (DTMF) is detected, the storage of the selected sound source is ended.

The method for storing the sound source including the above-described advertisement, music, message or English conversation in the user terminal 100, the sound source / video of the Internet server 500, if the user terminal 100 is available in the Internet mode The database 510 may be changed to a method of storing a sound source and / or a video including an advertisement, music, a message, or an English conversation in the user terminal 100. At this time, the sound source and / or the video data can be downloaded through the Internet browser instead of the above-described storage method using the DTMF command code or frequency combination.

3 is a flowchart illustrating a method for converting a telephone signal tone according to a preferred embodiment of the present invention. First, when a user inputs information such as a telephone number of a receiving terminal (not shown), the dialing unit 160 of the user terminal 100 is provided in the tone converter 200 in the form of a DTMF command code or a dialing packet. Transmitting through the vocoder 210 to the switch 300 (Sa1), the control program 224 in the flash memory 220 in the beep converter 200 detects a dialing signal and the predetermined number of the flash memory 220 The telephone number of the receiving terminal is temporarily stored in the location (Sa2). At this time, the control program 224 is to know the transmission state through the tone / voice detector 230 in the tone converter 200, and the sound source / video storage unit 226 through the control program 224 The user terminal 100 outputs an instruction to output the selected sound source and / or video to the user terminal 100 (Sa3). In this case, when a video including the sound source is selected, the video is output to the display unit 120 in the user terminal 100. The exchange 300 which transmits a signal such as a DTMF command code or a dialing packet from the dialing unit 160 in the user terminal 100 checks the call state of the called terminal. At this time, the response signal from the receiving terminal may be a ring back tone signal and a busy signal or a network busy signal.

The tone / voice detector 230 of the tone converter 200 checks the signal from the receiving terminal (Sa4). When the detected signal is a ringback tone signal, the exchange 300 receives the receiving side. A ringing tone signal is sent to the terminal, and a hook-off is checked (Sa5). In this case, when the receiving terminal is not hooked off, the control program unit 224 in the flash memory 220 in the tone converter 200 continuously outputs the selected flash memory in the tone converter 200 so as to continuously output the selected sound source signal. Instructing the sound source / video storage unit 226 in 220, the tone / voice detector 230 in the tone converter 200 continuously detects the signal from the exchange 300, the ring back tone signal is If no case is detected, the control program unit 224 checks the number of dialing times (Sa7), preferably terminates the call state if it is two or more times, and temporarily stores the called party number if the dialing is less than two times. To re-dial (Sa2). On the other hand, when the hook-off is made in the fifth step (Sa5), a call path between the receiving terminal and the user terminal 100 is formed through the telephone circuit unit 140 in the user terminal 100, and instead of the ring tone of the telephone. When the output sound source and / or the video is an advertisement, the counter value is preferably increased by “1” and stored in the counter storage unit 240 in the tone converter 200 as the call path is formed (Sa6). At this time, the re-dial number check can be changed by the user.

In other words, when the user terminal 100 attempts to make a call, the tone / voice detector 230 in the tone converter 200 is executed, and the signal transmitted from the base station 300 is the tone / voice detector 230. Detects the tone or the voice signal and stores it in the sound source / video storage unit 226 in the flash memory 220 through the control program 224 in the flash memory 220 in the tone generator 200 in case of a tone. The sound source and the moving image to the encoder 214 in the vocoder 210 in the signal converter 200, and the encoder 214 in the vocoder 210 sends the sound and the video in the user terminal 100 instead of the tone. Send it to the display. At this time, the tone / voice detector 230 continuously detects a radio wave transmitted from the base station 300, and outputs a sound source / video through the control program 224 when a signal other than a tone, that is, a voice signal, is detected at any moment. After that, the radio wave transmitted from the base station 300 is no longer detected and is immediately sent to the encoder 214 in the vocoder 210.

On the other hand, the communication between the beep converter 200 and the switch 300 may use a wire such as a cable, or may be performed through a wireless method used for a general mobile phone. In the case of using a wireless method, the beeper converter 200 may include a transceiver configured to transmit and receive a signal between the beeper converter 200 and the exchange 300 in a predetermined manner, for example, a radio frequency (RF) signal method. It may be further included.

In addition, the beeper converter 200 may be integrally assembled with the user terminal 100 or used as a separate type that is connected to the user terminal 100 using a port or a socket. .

In addition, in the embodiment of the present invention, a method for converting all the phone signals, such as ringback tone signal, busy tone signal and network busy tone signal, into a sound source and / or video desired by a user including advertisement, music, message, or English conversation. Although providing a ringback tone signal, a busy tone signal or a network signal such as a telephone signal can be serviced separately.

As described above, the method for converting a dial tone of a telephone according to the present invention may reduce time waste of waiting for a call state by providing various types of sound sources or video information that are more efficient and more pleasant than the dial tone of a conventional and monotonous conventional telephone. . In addition, the advertiser can maximize the advertising effect through one-to-one advertising, phone users can receive benefits such as rate discounts instead of listening or viewing the advertisement.

It will be appreciated by those skilled in the art that the embodiments of the present invention are merely exemplary and that various changes and modifications may be made without departing from the spirit of the present invention. For example, the telephone signal may be converted into a still image, that is, an image including a character or the like instead of the sound source and / or the moving image.
