BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile radiotelephone having a call message storage function and a message storing method thereof, and more particularly to a mobile radiotelephone having a call message storage function capable of storing and outputting important messages during a call. A method for storing messages.

In the prior art, there is no function to store a busy message, and is a device for guiding missed users, and is a base station for cordless telephone (CT) using a magnetic tape drive based on a landline telephone. There was a telephone answering device (TAD). However, such a TAD has a problem that a magnetic tape drive device is too large and very weak to impact and consumes a lot of driving power to be applied to a cellular mobile communication terminal which is frequently moved and has a high possibility of vibration or shock. Was used only in Base Station and not in portable portable devices.

Hereinafter, referring to FIG. 1, the configuration of the answering machine of the conventional cordless telephone CT will be described.

The conventional answering machine of the radiotelephone has a memory unit 11 for storing missed messages, all data and programs as shown in FIG. 1, and a voice synthesis circuit 12 for synthesizing the input data into a voice analog signal capable of making a call. And a low pass filter 13 for removing high frequency noise, a radio transmission modulator 14 for modulating so that it can be received by a general radiotelephone (CT), and control of all devices of the telephone and processing data transmission and reception according to a program. A control device 15 for controlling the digital signal, a wideband data (WBD) modem 16 for decoding and digitizing the received signal, a wireless receiving demodulator 17 for demodulating a signal from a mobile terminal device of a wireless telephone CT; It consists of an output device 18 for delivering a message to the user.

The automatic answering method using the automatic answering device of the conventional general landline telephone configured as described above is as follows.

The radio receiver demodulator 17 in FIG. 1 receives and demodulates the call signal from the portable device of the radiotelephone as a wideband data signal and applies it to the WBD modem 16.

The WBD modem 16 decodes and digitizes the signal applied through the radio receiving demodulator 7 and inputs it to the control device 15.

Accordingly, the controller 15 processes the digitalized data and sends a signal corresponding to the corresponding calling telephone number to the trunk line to raise the ring of the subscriber's telephone to call the user, and when the receiver picks up the receiver, the call is not made. do.

At this time, when the call contents are to be stored, a specific wireless signal is generated by pressing a specific button on the portable device of the wireless telephone, received through the wireless receiving demodulator 17, and the WBD modem 16 After decoded by digital processing, it is processed by the controller 15 and recorded in the memory or the answering machine 11. The memory or the answering machine 11 controls the control unit 15 to send a voice signal applied from the subscriber when there is no message storage control command during a call, between the control device 15 and the voice synthesis circuit 12. It simply passes through the. In addition, if there is a call from the subscriber, the control device 15 receiving the call signal of the subscriber rings for a predetermined time, and when the called user does not answer for a predetermined time, the control device 15 stores a memory or an answering device ( 11), the voice message data of the calling party is recorded in the memory or the answering machine 11 in response to the absence of being unable to answer the call. At this time, when the user presses another specific button of the mobile terminal, it is applied to the control device 15 through the radio receiving demodulator 17 and the WBD modem 16 and is analyzed and processed to the memory or the answering device 11. The recorded message is modulated into a radio signal by the radio transmission modulator 14 through the voice signal synthesizing circuit 12 and the low pass filter 13 and then transmitted to the user's portable terminal, thereby confirming the contents of the message. .

The speech synthesis circuit 12 reproduces the message recorded in the memory or the answering machine 11 as an audible analog signal and applies it to the low pass filter 13. The lowpass filter 13 removes unnecessary noise and then applies it to the radio transmission modulator 14. The radio transmission modulator 14 modulates and transmits the radio frequency at high frequency so that the user's portable terminal can receive it. In addition, the output device 18 receives the control signal of the control device 15 and displays the state where the caller's message is stored and the current CT state. This function allows you to check the status.

In this way, you can save the voice message sent by the other party and listen when the user needs it.

As described above, the prior art does not have a function of storing contents in a call in a portable terminal, and is recorded in an answering machine (TAD) provided in a base station of a radiotelephone (CT). Although a mechanical recording device is mainly used, when the mechanical recording device is used in a mobile radiotelephone, it is very weak to mechanical vibrations, so its life is shortened, its volume is very large, and it is inconvenient to move and carry. Since the consumption is very large, there was a problem that the reliability of the product falls.

Accordingly, an object of the present invention is to solve the above problems, and an object thereof is a mobile wireless telephone having a function of storing and outputting an important call message while a user talks with a counterpart using a semiconductor memory and a message storing method thereof.

Explain.

First, it is determined whether the mobile wireless telephone is busy (S31).

As a result of the determination 31, the operation is stopped if not in a call, and if it is in a call, the controller 27 checks whether a storage key, which is a call message storage button, is input from the keypad 28 (S32).

When the control device 27 recognizes that the message storage key is input, the control device 27 reads the address to store the call message from the semiconductor memory 29 (S33). ). In addition, the control device 27 receives the digital signal of the voice data transmitted and received by controlling the voice codec 25 and starts storing from the address of the semiconductor memory 29.

Thereafter, while increasing the memory address (S35), the end key, which is a button for storing voice data continuously talking to the semiconductor memory 29, and ending the message storage from the keypad 28 by the control device 27, It is determined whether the input (S36).

If the message storage end key, which indicates the end of the message storage in the above step, is entered, the operation of storing the call message in the semiconductor memory 29 is stopped, and if the message storage end key is not input, the remaining memory to be stored remains. It is determined whether there is (S37).

As a result of the determination (37), if the spare memory to be stored remains, the control device (27) is fed back to the step of reading the address to store the message in the semiconductor memory 29 (S33) to continue recording the call message.

A method of storing such important call messages in the semiconductor memory 29 and outputting and listening to the stored call messages will be described with reference to FIG.

First, the control device 27 determines whether the message output key having a function of reading and confirming the call message recorded in the semiconductor memory 29 from the keypad 28 is increased (S41).

As a result of the determination (S41), if the control device 27 does not recognize the input of the message output key, the operation is completed, and if the control device 27 recognizes the input of the message output key, the control device 27 is The semiconductor memory 29 is controlled to read the recorded call message from the corresponding address of the memory (S42).

The read call message is applied to the voice codec 25 under the control of the control device 27, is converted into an audible frequency through the voice codec 25, and is applied to the voice processor 26 to be transmitted to the speaker. You can check the saved call message.

At this time, the controller 27 continuously increases the address of the call message stored in the semiconductor memory 29 (S43), reads the message, and the increased address of the semiconductor memory 29 corresponds to the size of the memory in which the message is stored. It is determined whether the address is the same (S44).

As a result of the determination (S44), if the increased address of the semiconductor memory 29 is the same as the address corresponding to the size of the stored message memory, the operation is completed. Proceeding to step S42 of reading the address message.

As described above, the present invention can store and read important messages during a call with the other party, so that the important messages during a call can be stored and heard.
