Description

Portable wireless telephone and its operation method {Cellular phone and Method for operating the same}

The present invention relates to a portable radiotelephone and a method of operating the same, and particularly, a portable radiotelephone and a method for operating the portable radiotelephone that can communicate its intention to a caller without a direct reception when the receiver cannot receive it immediately due to personal circumstances It is about.

It's common to see people talking to us around the world from anywhere. It shows that the mobile phone population has spread, and the damage is not too small. For example, if you're focusing on a scene at a movie theater and it suddenly rings, you'll be offended. Another example would be the occasional drop in concentration of the instructor and the audience due to ringing during the training or during the lecture by the instructor.

Therefore, if the mobile phone users find it inconvenient to talk to the incoming call immediately as in the above situation, turn off the device in advance and use the voicemail or vibrate the mode as a means of informing the user that the call has been received. It is often used to set only blinking.

Nevertheless, there are a number of reasons why you may not be able to operate the device, and if your device makes a bell ringing in a public place, you may rush to remove the device, remove the battery or quickly open and close the flip. Get drunk.

However, in taking the above method, the problem is that the intention is not communicated between the sender and the receiver is very inconvenient.

That is, when the mobile phone is turned off, the voicemail service is automatically connected to the caller while informing the caller of the call charge, and most callers receive service due to the charge of the call charge, the rejection of the machine sound, and the inconvenience of storing messages. When you hang up a lot of times. As a result, the caller's message does not remain in the recipient's voicemail box, so the recipient only knows that a missed call is coming and does not know where the call came from.

In addition, the method of notifying the user by vibrating or blinking the LED also causes a hassle because the user needs to make a call out of the current place. It's only enough to make a call, so both the caller and the receiver are cumbersome, and it's difficult to achieve the purpose of the call.

In addition, if the receiver rings quickly in a public place, the caller repeatedly calls the receiver because the receiver's situation is not properly communicated to the caller. Despite the fact that it is not possible, it is a very unnecessary wasting action because it does not know exactly the situation of the receiver.

The object of the present invention is to record in advance the current situation or available time of the call in advance, if it is determined that it is inconvenient to immediately talk to the incoming call to the mobile phone user to solve the problems caused when using the mobile phone as described above The present invention provides a portable radiotelephone and a method of operating the response message to be automatically delivered to the caller.

A portable radiotelephone according to the present invention for achieving the above object is an antenna, a transceiver connected to the antenna for data transmission and reception, demodulating a received signal transmitted through the transceiver and modulating a transmission signal to output to the transceiver. A modulation / demodulation unit, an encoding and decoding unit for decoding a signal demodulated through the modulation and demodulation unit, and encoding a transmission signal output to the modulation and demodulation unit, a speaker for outputting a voice signal output from the encoding and decoding unit, and an input from an external device. A portable wireless telephone having a microphone for outputting a voice signal to the encoder and decoder, comprising: a key input unit capable of generating a key signal for setting a message recording mode and an auto answer mode, and a DSP module capable of storing and reproducing voice data And a recording mode setting key signal from the key input unit. When inputted, the system is switched to the recording mode, and the audio signal inputted through the microphone is signal processed to be stored in the DSP module. When the automatic response mode setting key signal is input from the key input unit, the system is switched to the automatic response mode. After that, when the incoming signal arrives through the antenna, it is characterized in that the control unit for controlling the overall system to connect the call to the automatic response message recorded in the DSP module is transmitted to the caller.

The portable telephone operating method of the present invention for achieving the above object is a method of operating a portable wireless telephone that can send and receive messages by processing the transmission and reception data, the automatic request to output the recorded response message for the incoming signal Detecting whether a response mode setting signal is input from a key input unit; Switching the system to an auto answer mode when an auto answer mode setting key signal is detected through the auto answer mode setting key signal input detection step; Detecting an incoming signal when the system is switched to the auto answer mode through the auto answer mode switching step; Instructing an incoming call for a predetermined time when the incoming signal is detected through the incoming signal detecting step; And if it is determined that the user does not answer the incoming call within the time set in the incoming call instructing step, connecting the call and transmitting a pre-recorded response message to the caller.

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

1 is a block diagram of a portable telephone having an automatic answering function according to the present invention, which includes a key input unit 10, a transceiver 20, an antenna 22, a modulator 30, an encoding and decoding unit 40, The speaker 42, the microphone 44, the controller 50, the LCD 60, and the DSP (Digital Signal Processor) module 70 are shown.

As shown in FIG. 2, the key input unit 10 is provided with a key 12 for setting a recording mode and a key 14 for setting an automatic response mode, and are configured to generate key signals corresponding to each key. Alternatively, it may be configured using the function keys 16 provided to take additional functions. The transceiver 20 separates the transmitted / received data and transmits the data to the antenna 22 or the modulator 30. The demodulation unit 30 demodulates the received data transmitted through the transceiver 20 and transmits the demodulated data to the encoding and decoding unit 40, and transmits a signal transmitted from the encoding and decoding unit 40 to the transmission and reception unit ( 20) to demodulate and deliver. The encoding and encrypting unit 40 encodes the demodulated signal through the modulation and demodulation unit 30, converts the encoded digital signal into an analog signal, outputs it to the speaker 42, and is inputted through the microphone 44. The voice signal is converted into a digital signal, and the converted digital signal is encoded and transmitted to the modulation / demodulation unit 30. The DSP module 70 processes, stores, and reproduces a voice signal through digital signal processing. When the message recording state setting key signal generated from the key input unit 10 is input, the controller 50 performs A / D conversion on the automatic response message input through the microphone 44 in the encoding and decoding unit 40. The digital signal is processed by the DSP module 70 and then stored. In addition, when the automatic response mode setting key signal is input from the key input unit 10, the system switches to the automatic response mode and when the incoming signal arrives, the response message data stored in the DSP module 70 is digitally processed to encode and decode the signal. After being encoded through the unit 40, the modulation and demodulation unit 30 and the transceiver 20 are transmitted to the sender. You will also have overall system control.

3 is a flowchart illustrating a method of recording an automatic response message in a method of operating a portable telephone according to the present invention. Referring to FIG.

First, let's say you want to leave a message about incoming calls when the mobile phone user is going to have a meeting after a while. The user generates a key signal by operating a key 12 for setting the system to a mode for recording a message in the key input unit 10. Then, the controller 50 switches the system to the mode for recording the response message because the recording mode setting key signal is generated in step 110 of detecting whether a key signal for recording the message is generated. Perform When the user inputs the call through the microphone 44, "Please call again after some time," the control unit 50 converts the response message into the digital unit in the encoding and decoding unit 40, and encodes the encoding. The step 130 of storing the DSP module 70 is performed. Then, in step 140 of detecting whether a message recording completion key signal is generated from the key input unit 10, if the recording completion key signal is detected, step 150 of terminating the recording mode is performed. In step 140-1, the recording completion key signal detecting step 140 determines whether the recording completion key signal is input for a predetermined time or the like. Do it.

When the recording completion key signal is input in the performing step as described above and the recording mode ending step 150 is performed, the control unit 50 displays the LCD 60 on the LCD 60 to indicate to the user whether to switch to the automatic response mode. When the key signal for requesting the switch is generated through the confirmation signal detection step 164 of selecting the answering machine mode, a step 166 of switching to the answering machine mode is performed.

4 is a flowchart illustrating a message automatic response method in a method of operating a portable telephone according to the present invention, which will be described with reference to the apparatus of FIG.

First, when the user generates a key signal to switch the system to the automatic response mode through the key input unit 10, the controller 50 detects whether the automatic response mode setting key signal is generated. In response to the mode setting key signal, a step 220 of switching the system to the auto answer mode is performed. In the step 230 of detecting whether the incoming call is detected, the step 240 of instructing the call by LED or vibration indicating that the call is received is performed to the user. At this time, if there is no user response even when instructing an incoming call during the set indication signal generation time, if the user response is not performed, the call connection step 260 is pre-recorded in the DSP module 70. In step 270, a message is encoded by the encoder and decoder 40 and modulated by the modulator 30 to be transmitted to the sender. At this time, the message transmission sound is not output to the speaker and the voice signal is not transmitted through the microphone. Then, in step 280 of detecting whether the message transmission is completed, when the message transmission is completed, performing step 291 of instructing the caller to record the message, and detecting whether the transmission of the recording guide message to the sender is completed. If it is detected as completed in step 292, a step 293 of switching to the caller message recording mode is performed. In operation 294, the message stored by the sender is stored. At this time, the voice of the caller, which is transmitted, is not output to the speaker 42. Then, if the completion signal is detected from step 295 of detecting whether the message recording completion signal is input by the caller, step 296 of terminating the caller message recording mode is performed and call termination step 300 is performed. In step 295 of detecting whether a message recording completion signal is input by the caller, if a time elapses in step 295-1 of detecting whether a recording completion signal is generated for a predetermined time, the caller message recording completion step is forcibly performed ( 296).

If it is detected that the user responds to the incoming instruction through the step 250 of detecting whether the user responds to the incoming signal, stopping the incoming instruction, releasing the auto answer mode and connecting a call between the caller and the receiver (250-). 1) is performed.

On the other hand, if the incoming call is not set in the auto answer mode, the incoming call is interrupted by the occurrence of the set key signal for switching to the auto answer mode and the call is connected, and the pre-recorded answer message is immediately sent to the caller. Be sure to

As described above, according to the portable telephone and its operation method according to the present invention, even if the portable telephone user can not receive it immediately due to personal circumstances, his / her intention can be effectively delivered to the caller.
