Technical Field of the Invention

The present invention can effectively deliver text information or attempt a telephone call to the other party's mobile communication terminal or a telephone equipped with a caller ID verification function while minimizing the user's identity exposure using voice and text information using the user's mobile communication terminal. The present invention relates to a method and a system.

Description of related technology

1 is a block diagram of a system for transmitting text information using a conventional mobile communication terminal. When the user inputs a text message to the transmitting terminal 11 and transmits it to the receiving terminal 14 in the state of the digitized text signal, the receiving terminal 14 restores the digitized text signal to the original text signal. A text message is displayed on the LCD of the receiving terminal 14.

According to the conventional method, if a text message is to be displayed on the receiving terminal of the other party, the text message must be input from the transmitting terminal in the form of a text message, and when input by voice, information cannot be transmitted to the other party in the form of a text message. However, when looking at the actual usage of the mobile terminal, there will be many cases in which the user merely wants to convey information or intention without exposing his or her voice to the other party. In such a case, according to the conventional method, a method of inputting a text message is used. However, the conventional text message input takes time and inconvenience, and thus there is a problem that text message transmission is cumbersome or dangerous during driving such as driving. If the user inputs a message by voice, if the additional service of the mobile communication service provider delivered in the form of a text message is available to the receiving terminal, the number of mobile communication service users using the mobile communication service will increase. The mobile communication service provider can provide a subscriber with a convenient additional service at a relatively low cost, thereby having the advantage of securing a subscriber.

2 is a block diagram of a conventional caller ID system. According to the conventional caller ID verification system, when a user of a mobile communication terminal attempts to make a telephone call by inputting a telephone number of a receiving terminal using the transmitting terminal 21, such a call request signal 6 is transmitted to the repeater in the switching center 7 7 again transmits this to the receiving terminal 24 in the form of a telephone reception signal 8. In this case, the receiving terminal 24 receives the telephone reception signal and notifies the receiver of the call in various forms such as a bell, vibration, and silence, and simultaneously displays the telephone number of the transmitting terminal 21 on the LCD screen. In the conventional method, when a calling party does not want to send a calling party number, a predetermined signal, for example, '* 23' is sent to the switching station along with the calling party's telephone number, so that the switching station transmits information about the calling party number to the calling terminal. There was a system that does not provide services. According to the caller ID verification system shown in FIG. 2, when a user of a mobile communication terminal attempts to make a telephone call to a sender terminal without revealing his or her identity, it is cumbersome to enter or select an additional code. Instead, no means have been devised to allow the receiving party to verify this by passing information that can be used to identify another person.If the caller ID non-exposure mode is selected, the receiving party rejects the telephone call or has some unpleasant feelings toward the sending party. You can also According to the conventional method, the sender has only two choices, whether it exposes its own phone number or transmits no caller identification information, so the sender sends the minimum information that can verify his or her identity except for the calling party number. Attempting to make a phone call was impossible. This may not meet the original purpose of the sender attempting the telephone call.

Therefore, in such a case, there is a technical necessity of transmitting a telephone reception signal to a receiver while simultaneously transmitting information in a form of text or the like that the receiver can identify the sender's identity.

An object of the present invention is to provide a method and system that allows a user to transmit a text message or attempt a telephone call while delivering only minimal identification information without exposing his or her tone or caller ID using a mobile communication terminal. It's there.

Another object of the present invention is to solve the subscriber's convenience and identity exposure by allowing the mobile operator to provide such subscribers with voice-to-text conversion services or simultaneous delivery of telephone signals and identification information. Thereby, it is intended to increase subscribers.

Description of the Preferred Embodiments

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 3 to 5. At this time, the description of unnecessary configuration is omitted in order to clarify the gist of the present invention.

2 is a block diagram of the speech-to-text conversion system of the present invention. In FIG. 2, the transmitting terminal 21 and the receiving terminal 24 may communicate with the switching center of the mobile communication service provider or without passing through the base station. The voice-to-text converter 33 is installed in the switching center of the mobile communication operator. The voice-to-text converter refers to an apparatus for converting digitized voice information transmitted from a transmitting terminal into digitized text information that can be transmitted to a receiving terminal. The type of information input to the speech-to-text converter is digital information consisting of 0,1 binary signals, and the information output from the speech-to-text converter is also digital information consisting of 0,1 binary signals. Algorithms are based on a method of modulating a digital signal into a digital signal. Conventional digital modulation refers to a process of transforming a digital symbol into a waveform to suit the characteristics of a channel, but if a specific digital signal can be transformed into another type of digital signal according to the purpose of channel suitability, It is possible to transform a digital signal that can be restored into text information by a conventionally known voice recognition technique. If the digital-to-digital conversion is not easy, the voice-to-text converter may be configured by combining the D / A converter and the A / D converter. In this case, in a voice-to-text converter that combines a D / A converter and an A / D converter, when a digital signal modulated with a voice signal is input to the D / A converter, the analogized voice signal is restored, and the normal voice recognition is performed again. According to the algorithm, after converting the text information into the A / D converter, the digitized text information is output. Digital signals that modulate audio signals have their own waveforms, and digital signals that can be restored to text information also have their own waveforms. It may also be assumed to use a scheme of storing the data in a back and the like and interworking it with each transmission. In order to solve the problem that the tone is different for each person, a probability distribution method may be used to determine a probability within a certain range and determine that it is associated with a specific text signal when it is within the probability range. The signal output from the speech-to-text converter in the switching center should be a digital signal that can be converted into text information at the receiving terminal. The digitized text information 13 is transmitted from the switching center of the mobile communication provider to the receiving terminal 34, and the receiving terminal 34 receives the message and displays a message in a text form on the LCD screen of the receiving terminal. Through this process, the voice information input to the transmitting terminal 31 may be displayed in the form of a text message at the receiving terminal 34.

4 is a diagram illustrating another embodiment of the speech-to-text conversion system of the present invention.

The present invention also includes a configuration for transmitting voice information to a landline phone as text information or to a client connected to the Internet in the form of a text mail through voice information-to-text conversion at a switching center using a wireless mobile terminal. A process of transmitting text information via the wired telephone network or the Internet through the voice information of the present invention will be described with reference to FIG. First, in a configuration using a wired telephone network, a liquid crystal display capable of displaying text information through a general telephone switching network 44 connected to a mobile communication system after voice information transmitted from a wireless terminal 41 passes through voice information-to-text conversion 43 at a mobile communication switching center 42. It is transmitted as text information to the landline telephone 45 equipped with. On the other hand, in the configuration of transmitting voice information to a specific e-mail address using the Internet network 45 connected to the mobile communication exchange station, first select the voice-e-mail transmission mode on the mobile terminal 41 and input the e-mail address of the party to send or the e-mail stored in the mobile terminal. When information is input by voice after searching and selecting an address, it is transmitted to the mobile communication switching center 42 together with identification information indicating a voice-to-text conversion mode through voice information modulation. The mobile communication station determines that the transmitted information is a signal that needs to undergo voice-to-text conversion, converts the transmitted information signal to voice information-to-text information as described in FIG. 3, and then, through the internet network connected to the mobile communication exchange, The data is sent to the email server managing the other party's email or the server 46 managing the webmail.

In addition, when the user selects the voice-text mode and the e-mail service mode of the mobile terminal and inputs and transmits the voice information, the exchange determines that the transmitted information signal includes the e-mail transmission mode. It is possible to adopt a configuration in which the text information is provided to the mobile terminal, and at the same time, the text information is transmitted to the server of the wireless communication service provider itself or another server providing the email service to transmit the text information to the other party's email address. The above configuration saves the subscriber's phone number and its corresponding email address in advance with the text service to the mobile switching center without entering or selecting a specific email address in the mobile terminal, and converts the transmitted voice information into text information. It is possible to take a structure that delivers the converted text information to the server and mobile terminal managing the corresponding email at the same time. The present invention can also be configured to send the text information to the e-mail management server only when an attempt is made to send text information to the mobile terminal but the text cannot be received, such as when the mobile terminal is in an area in which the mobile terminal cannot communicate or is turned off. have. In another aspect, the present invention can be transmitted to the mobile terminal receiving the wireless Internet service through the existing wireless Internet network, the text information through the voice information-text information-conversion in the mobile switching center.

5 is a block diagram of a system for simultaneously transmitting a telephone signal and text information of the present invention.

As shown in FIG. 2, according to the conventional caller ID system, when the sender terminal enters the phone number of the receiver terminal and presses the SEND button, the transmitter terminal sends a call request signal to the mobile communication service provider. If a transmitter installed in the operator's exchange station receives this and transmits a call reception signal to the receiving terminal with the calling party's calling party number information, the calling party number is displayed on the LCD of the receiving terminal and the reception sound or vibration It generates a telephone reception signal such as. In the conventional caller ID verification service, the sender number can be avoided from being exposed to the receiver by inputting a sender number refusal command from the sender. However, in this case, the receiver cannot transmit any information about the identity of the sender to the receiver. Rejecting a call may occur. In order to solve such a problem, the fifth embodiment of the present invention may add a caller information transmission mode to the transmitting terminal 51. When the sender selects the sender information transmission mode from the menu of the terminal 51, the sender terminal automatically transmits a caller ID non-exposure command such as a conventional '* 23' command or simply '*' to the switching center of the mobile service provider. The calling party number is not exposed to the receiving side, but the sending terminal transmits caller identification information in the form of voice or text to the switching center of the mobile communication service provider. Here, the caller identification information in the form of voice or text may be input to the terminal in advance before the user attempts to make a phone call, or may be inputted by voice or text after selecting the caller information transmission mode.

In order to avoid the burden on the communication channel, the caller identification information which can be transmitted to the mobile communication provider is informed in advance, and when the mobile communication provider receives the caller information transmission signal from the sender, the caller identification information that has been notified in advance is sent to the receiver in the form of a text message. The method of sending a call signal together with the transmission may be selected. When the sender selects the sender transmission mode, the telephone call request signal is transmitted to the voice-to-text converter 53 and the repeater 52 of the mobile communication switching station together with the caller identification information except for the caller's telephone number. The repeater 53 in the switching center transmits the telephone reception signal to the receiver by calling the receiver terminal 54 of the telephone number designated by the telephone call request signal from the transmitter terminal 51. When the sender identification information to be transmitted by the sender is in the form of a voice, as described in the embodiment of FIG. 3, the digitized voice signal is transmitted to the speech-to-text converter 53 of the switching center, while the sender confirmation information that the sender is to transmit. Is in the form of text, it is transmitted to the receiving terminal 54 in the form of digitized text information through the repeater 52 without the need for a speech-to-text converting apparatus according to a conventional text message transmission scheme. The digitized voice is also modulated into a digital signal that can be restored to a text signal by the speech-to-text converter 53 of the switching center and then transmitted to the receiving terminal 54 in the form of digitized text information 21. In either case, the receiving terminal 54 displays the caller identification information transmitted by the transmitting side in the form of a text message on the LCD screen. What is important here is that the telephone reception signal and the digitized text signal are simultaneously transmitted to the receiving terminal 54. This is the same as that in the conventional caller ID verification system, the caller ID is displayed on the LCD screen of the receiver terminal while the telephone receiver signal is generated by the receiver terminal.

Caller identification information is displayed in the form of a text message instead of the calling party number on the LCD of the receiving terminal.

The simultaneous transmission system of telephone reception signal-text information of FIG. 5 is designed to transmit text information to a specific email address through a wired telephone or an Internet network with a text display device attached through an existing telephone network such as a public line switching telephone network described in FIG. It can be applied to a system that transmits. The detailed system configuration and description of the information transmission process will be omitted since it is similar to FIG.

According to the present invention described above, the user can transmit a text message to the other party's mobile communication terminal through a mobile communication terminal by a voice signal while driving a car or other movement, thereby eliminating the inconvenience of inputting a text message using both hands ( When sending a text message to a conventional mobile communication terminal, it is difficult to use one hand, at least two hands must be used, and it takes at least several seconds.) By transmitting the voice of the transmitter to the receiver, the tone of the transmitter is exposed or emotionally transmitted. You can feel free to actively communicate your opinion or information. The mobile service provider can also expand the subscribers by providing the voice-to-text conversion service as a supplementary service to the subscribers. In addition, existing subscribers, especially those who are not familiar with text message input, can easily reach the other party. It is possible to use the text message delivery method, which is a more accurate method of information transmission than voice message, and it is necessary for the sender to avoid the exposure of his / her tone to the receiver or to have an emotion that he does not want to talk directly with the receiver. By enabling the transfer of information, there is an effect of increasing the utilization of the mobile communication service.

The present invention is not limited to the above-described embodiments and it will be apparent to those skilled in the art that various modifications may be made within the spirit and principles of the present invention with reference to the specification of the present invention. .
