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

1 is a block diagram of an embodiment of a wireless communication terminal having a privacy provision function during a call according to the present invention.

As shown in FIG. 1, a wireless communication terminal having a privacy protection function during a call according to the present invention operates and controls a wireless transmission / reception device 101 for transmitting and receiving a signal wirelessly through an antenna and the wireless communication terminal. In response to the privacy request signal, a preset sound (ringtone sound source) is output to the voice output device (eg, speaker) 105 while the call is received, and the ear jack of the other party received from the wireless transmitter / receiver device 101 is connected. A user voice from a signal (a sound and a user voice mixed signal) input through the voice input device (microphone) 108 by using the user voice signal stored in the storage device 104 and outputting through the To filter and transmit a user voice signal to the other party (the other wireless communication terminal) by filtering the signal. Under the control of the calculation / control device 103 and the calculation / control device 103, the signal received from the wireless transmitting / receiving device 101 is converted into voice and output to the ear jack 109, and sound is output. It outputs to the device (speaker) 105, converts the voice received from the voice input device (microphone) 108 into a signal and transfers it to the operation / control device 103 to transmit through the wireless transmission and reception device 101 Codec (102), a program for driving the wireless communication terminal and a file system (image, character, icon), a program for providing privacy, a sound source and a voice input device (108) Storage device 104 that stores the received user voice data, etc., a voice output device (eg, speaker) 105 for outputting the sound received from the codec (102), the calculation / control device (103) ) Control LCD (106) for outputting the screen according to, input device (keypad) 107 for receiving a phone number, menu selection information, ringtone selection signal, privacy request signal, etc. A voice input device (microphone) 108 for transmitting to the codec 102 and an ear jack 109 for outputting the other party's voice received from the codec 102 to an earphone. .

Here, the sound output through the voice output device 105 uses a sound source stored in the storage device 104, which may be previously selected by the user.

In more detail, the operation / control device 103 previously stores the user's voice signal through the voice input device 108 in the storage device 104 and receives the voice input through the voice input device 108 during a call. It is used to filter the user voice signal from the 'mixed sound and user voice' signal.

On the other hand, a wireless communication terminal having a privacy providing function during a call according to another embodiment of the present invention drives and controls the wireless communication terminal, and voices a preset sound source (ringtone sound source) during a call according to a privacy request signal. While outputting to the output device (for example, a speaker) 105, the sound signal stored in the storage device 104 to output the voice signal of the other party received from the wireless transmitting and receiving device 101 through the ear jack 109 The user voice signal is filtered from a signal input through the voice input device (microphone) 108 (a signal mixed with sound and the user voice) using a sound source, and the user voice signal is transmitted through the wireless transceiver 101. Computation / control device 103 for controlling the transmission to the other side wireless communication terminal), and programs for providing privacy, sound sources, etc. And a storage device 104 which stores, the respective components are outside of the respective components and their configuration and operation explained in the above embodiment is the same.

2 is a flowchart illustrating a method for providing privacy during a call in a wireless communication terminal according to the present invention.

First, the operation / control device 103 receives a user voice through the voice input device 108 and stores the user voice in the storage device 104 (201).

Thereafter, as the operation / control device 103 receives the privacy request signal through the input device 107 (202), it is set to the privacy protection mode (203).

Then, when the call is connected (204), and outputs the sound (ringtone sound source) to the voice output device (for example, speaker) 105 to determine whether the received voice or the transmitted voice (206).

If the result of the check 206 is a received voice, the operation / control device 103 outputs the voice of the other party received from the wireless transceiver 101 through the ear jack 109 (207). Proceed to the process.

On the other hand, if the confirmation result 206, the transmission voice, the operation / control device 103 is input through the voice input device (microphone) 108 using the user voice data stored in the storage device 104 The user voice signal is filtered from the received signal (a signal mixed with sound and user voice) (208), and the user voice signal is transmitted to the other wireless communication terminal through the wireless transmitting / receiving apparatus 101 (209).

Then, it is determined whether the call is terminated (210).

As a result of the determination 210, if the call is not terminated, the process proceeds to step "205" to continue the call.

On the other hand, the determination result 210, if the call is terminated, it ends.

3 is a flowchart illustrating another embodiment of a method for providing privacy during a call in a wireless communication terminal according to the present invention.

As the operation / control device 103 receives the privacy request signal through the input device 107 (301), it is set to the privacy protection mode (302).

Then, when the call is connected (303), the operation / control device 103 outputs a sound (ring sound source) to the voice output device (e.g., speaker) 105 (304), whether the received voice or the transmitted voice Check (305).

If the result of the check 305 is a received voice, the operation / control device 103 outputs the voice of the other party received from the wireless transceiver 101 through the ear jack 109 (306), " 309 " Proceed to the process.

On the other hand, if the verification result 305, the transmission voice, the operation / control device 103 is received through the voice input device (microphone) 108 using a sound source stored in the storage device 104 The user voice signal is filtered from the signal (a signal mixed with the sound and the user voice) to transmit the user voice signal to the other wireless communication terminal through the wireless transceiver 101 (308).

Then, it is determined whether the call is terminated (309).

As a result of the determination 309, if the call is not terminated, the process proceeds to "304" to continue the call.

On the other hand, if the call is terminated, the determination result 309, it ends.

In the above-described embodiment of the present invention, the sound is output to the voice output device (speaker) to provide privacy to both the transmitted voice and the received voice, but as another embodiment according to the present invention, the received voice or the transmitted voice The sound output process may be performed only in the case of the transmission voice by checking the recognition. This is because the received voice is generally output through the ear jack, so that it is less likely to be heard by people around it, which is in accordance with the object of the present invention to provide privacy even if only the user's transmitted voice is protected.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, while outputting a preset sound through the external speaker during the call, and outputs the other party's voice through the ear jack and through the microphone using the pre-stored user's voice data or the pre-stored sound source By filtering the user's voice signal from the received signal and transmitting it to the other party, there is an effect that can protect the contents of the call to the people around.
