PORTABLE COMMUNICATION DEVICE WITH A VARIABLE OUTPUT VOLUME ACCORDING TO THE RECEIVING SIGNAL AND ITS REALIZING METHOD}

The present invention relates to a mobile communication terminal and its implementation method in which the output volume is variable in accordance with the received signal, and more particularly, when making a call using a mobile communication terminal such as a mobile phone (ringback tone) and non- The present invention relates to a mobile communication terminal and a method of implementing the same, which add a function of allowing a user to listen to a mobile phone without bringing the mobile phone close to the ear.

1 is a block diagram schematically illustrating a configuration of a conventional general mobile communication terminal.

In FIG. 1, the wireless module 20 is connected to a base station through an antenna to perform a function of transmitting and receiving a signal, and the signal processor 30 demodulates a received signal (for example, a ringback tone signal, a busy signal, and a voice signal). It outputs to the ear speaker 50, and modulates the voice signal of the user input through the microphone 40 and transmits it to the wireless module 20.

The controller 10 controls the radio module 20 and the signal processor 30 to perform the above functions smoothly, and the operation of the controller 10 is determined by a program stored in the memory 80. In addition, when the incoming call amplifies the call sound data stored in the memory 80 through the amplifier 70 and outputs to the call sound speaker (60).

In addition, the display unit 90 is composed of a liquid crystal display or the like, and displays the state of the mobile communication terminal, the caller ID, etc. as an image, and the key input unit 100 is composed of various function buttons including a numeric pad.

Here, the ear speaker outputs the other party's voice when the user calls the mobile communication terminal with his / her ear. In general, the ear speaker outputs the voice of the other party. The output is large.

When making a call with a mobile phone in the related art, after pressing a call number (telephone number) of the other party, pressing the 'call' button to initiate a call, and the base station receives the signal and sends a call signal to the called party's mobile phone. At the same time, the calling party sends a ring back tone signal. At this time, a busy signal is sent when the called party is busy.

At this time, the ringback tone signal and busy signal are all output to the ear speaker. Therefore, the caller should press the 'call' button to initiate the call and then hold the mobile phone to his ear until the other party answers the call.

In recent years, the ringback tone signal and the ring tone signal are directly transmitted from the base station to be outputted. Accordingly, music, voice, and other natural sounds are used as the signal sounds rather than the conventional uniform tone.

This technology is especially accepted and activated in terms of mobile advertising. When the user outputs the ringback tone signal using, for example, advertising music or voice, the ringback tone signal is output through the ear speaker, so the user does not touch the mobile phone to his ear. If you don't, you won't be able to get the full effect of the advertisement.

Moreover, recently, commercialization of mobile communication terminals as multimedia capable of transmitting and receiving not only voice but also video using mobile communication terminals has come to the fore. In the advertising industry, instead of ringback tone signals or ring tone signals, advertising music or voices are used. In addition to transmitting, I am also considering a method of maximizing the effect of advertising by transmitting an image.

However, in the case of advertising by using the conventional ringback tone signal, the user must hold the mobile phone to the ear to know the call connection state, there is a problem that the user can not see this even if the image is sent.

The present invention has been made to solve the above problems, by adding a kind of on-hook function to the mobile communication terminal to output a large ringback tone signal and busy signal, and output a small voice signal of the other party when the call is connected In addition, it enables users to know the state of a call even when the mobile communication terminal is not held in their ears, and maximizes the effect when advertising or outputting various music or voice using a ringback tone signal, and especially using a video together. It is an object of the present invention to provide a mobile communication terminal and a method for implementing the same, which add an on-hook function to solve a problem caused in the case.

In order to achieve the above object, the mobile communication terminal according to the present invention, the ear speaker to output the ring tone (ringback tone), non-voice and call voice, the ring tone speaker to output the ring tone (ring tone), and the user's voice A microphone for receiving input and converting the signal into an electrical signal, a wireless module for transmitting and receiving a ringback tone signal, busy signal, and voice signal through an antenna, a signal processor for demodulating or receiving a signal for demodulating or receiving a received signal, and the state or transmission and reception of a terminal. A display unit for displaying a number, a key input unit, a memory for storing a program for performing a function of a terminal, a phone number, ring tone data, and the like, and a control unit for controlling a function of each component device according to the program stored in the memory. As a mobile communication terminal provided,

A signal identifier for identifying a signal received at the time of transmission, and a switching switch for switching the signal demodulated by the signal processor to the ear speaker or the call tone speaker under the control of the controller; The control unit identifies a signal received at the time of transmission and outputs the ring back tone signal and the busy signal to the ring tone speaker, and outputs the ring tone signal to the ear speaker when a call signal is connected to the called party. .

According to another aspect of the present invention, a portable communication terminal includes a signal identifier for identifying a signal received at the time of transmission, and when outputting the signal demodulated by the signal processor to the ear speaker under the control of the controller. Further comprising a volume controller for adjusting the volume, the control unit identifies the signal received at the time of transmission, and if the ringback tone signal and busy signal to increase the volume by the volume controller, and the called party and the call path is connected When the voice signal is received, the sound is reduced and output to the ear speaker.

Here, the signal identifier is composed of a band pass filter and a comparator, and may have a frequency band of the received signal to identify a ringback tone signal, busy signal, and voice signal.

Alternatively, the ringback tone signal and the busy signal transmitted from the base station may include an identification code, and the signal identifier may identify the type of signal by detecting the identification code.

Further, it is preferable that the control unit outputs a ringback tone signal and a busy signal to the ring tone speaker or to the ear speaker by a user's operation by the key input unit.

According to another aspect of the invention, the switch is controlled by a button installed on the outer surface of the mobile communication terminal, the signal identifier does not include at this time, the user according to the state of pressing the button and the state of not pressing the receiving Outputting a signal to the ring tone speaker or the ear speaker is characterized in that it is switched.

Similarly, the volume controller is controlled by a button installed on the outer surface of the mobile communication terminal, wherein the signal identifier is not included, and the volume of the received signal is increased depending on whether the user presses the button or not. It is characterized in that the output at a small volume is switched.

Alternatively, the button is a sensing sensor installed on the surface on which the ear speaker is installed, and if it is determined that the user is holding the mobile communication terminal close to the ear, and it is determined that the user is holding the ear close to the ear, the call tone speaker is used. It is possible to output at a low volume with the ear or the ear speaker, and output at a low volume with the ear speaker when it is determined that the user is not close to the ear.

In this case, if the sensitivity of the microphone is made high, the portable terminal unit itself will include functions as hands-free.

A method for implementing an on-hook function in a mobile communication terminal according to the present invention includes a first step of demodulating a signal received from a base station at the time of an outgoing call, and identifying a demodulated signal to determine whether a call connection tone signal or a busy signal is used. A second step of determining whether the received signal is a ringback tone signal or a busy signal, and a third step of outputting it to a ring tone speaker, and outputting it to an ear speaker when a call signal is connected to a called party and a voice signal is input. It is characterized by comprising a fourth step.

Here, the ear speaker is a speaker that can adjust the volume, wherein, in the third step, the ring back tone signal and busy signal are followed by a volume that the user of the mobile communication terminal can hear without holding the ear speaker close to the ear. The audio signal may be output to a speaker, and in the fourth step, the voice signal may be output at a small volume such that the user can hear the ear speaker of the portable communication terminal close to the ear.

The ring back tone signal and busy signal are voice signals transmitted from a base station, such as voice, music, and natural sound, and the base station transmits an identification code included in the signal, and at this time, the identification in the second step. The process may be performed by detecting the identification code. In addition, the ring back tone signal and busy signal transmitted from the base station may include a video signal in addition to an audio signal such as voice, music, and natural sound, and at this time, the ring back tone signal and busy signal are output in the third step. The video signal may be output to the display unit.

Hereinafter, with reference to the accompanying drawings will be described in more detail.

2 is a block diagram showing an example of a mobile communication terminal according to the present invention.

As shown in FIG. 2, the mobile communication terminal in the present embodiment includes a control unit 10, a wireless module 20, a signal processor 30, a microphone 40, an ear speaker 50, and a ring tone speaker 60. ), An amplifier 70, a memory 80, a display unit 90, a key input unit 100, and a signal identifier 110 and a changeover switch 120.

The signal identifier 110 identifies a ring back tone signal, a busy signal, and an audio signal from the received signal. When the signal identifier 110 demodulates the signal received from the base station through the wireless module 20 in the signal processor 30, the signal identifier 110 identifies whether the demodulated signal is a ringback tone signal, a busy signal, or a voice signal of the other party. The control unit 10 is notified of the result.

When the signal received by the signal identifier 110 is a ringback tone signal or busy signal, the controller 10 controls the switching switch 120 to output the ringback tone signal or busy signal to the call tone speaker 60. . At this time, when the called party receives a voice signal of the other party in response to the call, and the signal identifier 110 detects this and notifies the controller 10, the controller controls the switching switch 120 so that the voice signal is an ear speaker. Output to (50).

Thus, when a user makes a call using a mobile communication terminal such as a mobile phone, the user does not need to hold the mobile phone close to the ear until the other party answers. Moreover, this can be used more effectively when the ringback tone is recently replaced with any music or advertisement voice, and when the user transmits a video advertisement or a character when transmitting the ringback tone signal, You don't need to hold your phone close to your ear, which makes it useful for you to watch video ads and characters.

There may be various methods for identifying the received signal in the signal identifier 110, but an example of identifying the received signal using the frequency band of each signal is illustrated in FIG. 3.

3 illustrates a signal identifier 110 including first to third band filters and first to third comparators connected to each band filter. It is generally used that the ringback tone signal has a frequency component of 440 Hz and 480 Hz, and the busy signal has a frequency of 480 Hz and 620 Hz, so that the first band filter is a band filter passing a frequency of 440 Hz, and the second band. The filter is a band pass filter that passes a frequency of 620Hz, and the third band pass filter is a low pass filter that passes a frequency of 440Hz or less.

The first to third comparators output a 'high' signal when the signal output from each band filter is greater than or equal to a predetermined threshold value, and otherwise output a 'low' signal. With this configuration, if only the output value of the first comparator is 'high' and the rest are 'low', it is a ringback tone signal, and if the output value of the first comparator is only 'high' and the rest are 'low', it is a busy signal. If only the output value of the third comparator is 'high' or two or more output values are 'high', it is determined as a voice signal.

However, in such a configuration, there are various aspects to be applied when the base station transmits music or voice in place of the ringback tone signal or busy signal.

Therefore, when the base station transmits a ringback tone signal or busy signal to the mobile communication terminal, the base station includes an identification code indicating the type of the signal, and the signal identifier 110 detects the identification code to determine the type of the signal. It would be desirable to.

4 is a block diagram showing another example of a mobile communication terminal according to the present invention.

In the present embodiment, it is the same as the conventional mobile communication terminal except that the signal identifier 110 and the volume controller 130 are further provided. Of course, the ear speaker 50 here should be a speaker that can be output at a volume enough to hear the user without the user close to the ear, such as a ring tone speaker (60).

The signal identifier 110 identifies whether the received signal is a ringback tone signal or busy signal or a voice signal, and notifies the controller 10 of the result. When the received signal is a ringback tone signal or busy signal, the controller 10 controls the volume controller 130 to output the ringback tone sound and the busy sound to the ear speaker 50 at a large volume. If a voice signal is received on the way, the volume controller 130 is controlled to output a small volume.

In this case, although the call sound speaker 60 may be removed by configuring the call sound to be output at a high volume to the ear speaker, for example, in the case of a clamshell mobile phone, the ear speaker 50 may be controlled at a high volume to output the call sound. If the folder is folded, the output sound does not spread well to the outside.

In the above two embodiments, the function of outputting the ringback tone signal and busy signal at a high volume so that the user does not have to hold the mobile communication terminal to the ear until the counterpart responds when the user makes a call, for example, is operated by the key input unit 100. It's a good idea to let the user set things up. It is sometimes difficult to output ring back communication calls and busy signals at high volume depending on the time and place.

5 is a view showing another example of a mobile communication terminal according to the present invention.

FIG. 5 shows an example of a mobile communication terminal in which the changeover switch 120 or the volume controller 130 is not controlled by the control unit 10 but controlled by an operation of a button 140 provided on an outer surface of the mobile communication terminal. have.

Button 140 is preferably disposed on the side of the mobile communication terminal as shown in FIG. This is a position where a finger can be easily pressed when the user lifts the mobile communication terminal with one hand. According to the present embodiment, when a user makes a call using a mobile communication terminal, the user presses the call number (phone number) of the called party, presses the 'call' button, and simultaneously holds the mobile communication terminal with one hand while If the button 140 is pressed with a finger, while the button 140 is pressed, the received signal is output to the call tone speaker or the ear speaker with the volume increased. When the user moves the finger away from the button 140, the button 140 returns to its original position by the spring action, and thus the received signal is output to the ear speaker or to the ear speaker with a low volume. Of course, on the contrary, it is possible to output at a low volume while pressing the button 140, and to be output at a high volume without pressing the button 140.

In this case, the signal identifier becomes unnecessary, and the changeover switch and the volume controller are controlled by the button 140. However, the changeover switch may be a button 140. If the output path of the received signal is configured to be switched by the button 140, there is no need to provide a changeover switch separately.

In addition, in the present embodiment, the button 140 is provided separately, but it is also possible to set the existing function button installed in the mobile communication terminal to perform the above function when transmitting.

In FIG. 6, the switching switch 120 or the volume controller 130 is not controlled by the control unit 10, but the sensing sensor 150 is installed on the surface where the ear speaker of the mobile communication terminal is installed so as to be controlled by the sensing sensor. An example of a portable communication terminal is shown.

In the embodiment of FIG. 5, the user can arbitrarily select the output volume of the received signal by operating a button, while in the present embodiment, the output volume is automatically switched by the sensor 150.

As shown in FIG. 6, the detection sensor 150 may be installed on a surface on which an ear speaker that is placed close to the ear for a call is installed.

The detection sensor 150 is, for example, a temperature sensor or an optical sensor, and determines whether the user is holding the portable communication terminal close to his or her ear. In the case of using the detection sensor 150, when it is determined that the user is holding the mobile communication terminal close to the ear, the received signal at the time of transmission is output to the ear speaker, and in the case of the ear speaker capable of volume control, the volume is output at a small volume. On the contrary, when it is determined that the user is not holding the mobile communication terminal close to the ear, that is, when the detection sensor 150 does not detect anything, the ring back tone signal and busy signal at the time of transmission are converted into the ring tone speaker, and volume control is performed. If possible, the speaker outputs a loud volume. In this case, only the ring back tone signal and the busy signal may be output at a high volume, and the voice signal may be output at a loud volume in the case of a ring tone speaker or an ear speaker capable of adjusting the volume.

In the case of using the sensor 150, the signal identifier is unnecessary as in the case of using the button 140, and the changeover switch and the volume controller are configured to be controlled by the sensor 150. In particular, when the sensor 150 to detect the object within a predetermined distance and to detect the separation distance, it may be to adjust the volume by controlling the volume controller according to the separation distance. That is, the closer the user is to the mobile terminal, the smaller the volume of the output sound.

When using the sensor 150, the user automatically adjusts the output sound according to the state of using the mobile terminal, the user does not always have to hold the mobile terminal close to the ear, and recently spread When the ringback tone signal is replaced with music or voice, the user can listen without touching the ear, and when a video or character such as a video is output with the ringback tone signal at the time of transmission, In the case of using it, the effect of a visual advertisement cannot be acquired unless it is based on this invention.

As explained above, according to the present invention, the following effects can be obtained.

First, since the ringback tone (call connection tone) or non-voice sound is output to the ring tone speaker or the ear speaker with volume control at the time of origination, the user does not have to hold the mobile terminal to the ear until the call is connected. In addition, when the called party responds to the call, the signal is identified and the volume is reduced or output to the ear speaker. Therefore, the call content can be prevented from being output to the outside.

Second, because the mobile communication terminal does not have to be held in the ear until the called party responds at the time of origination, the ringback tone signal is replaced with music, voice, natural sound, etc. Advertisement to surrounding people can be obtained, and in particular, in case of transmitting a video signal such as a video or a character in addition to an audio signal such as music, voice, etc. in place of the ringback tone signal, there is no effect. You will not be able to get it.

Third, by installing the button on the mobile communication terminal, the user can conveniently switch the output form of the reception signal, and in particular, if the sensor is installed, the output form is automatically switched according to the use state, so it can be used conveniently. . In particular, in this case, the output form is switched for all received signals of the ringback tone signal, busy signal, and voice signal, so that the mobile communication terminal itself has a function of hands-free.
