Description

Character communication system using only one code

The present invention relates to a character communication system using only one code capable of expressing a character using a number and a special key button of a numeric keypad.

In general, in order to send a text message to the other party, a character is written using a computer keyboard and sent, or a document previously written with a pen is sent through a fax. By the combination of the number of the button by the way to express the consonants, vowels of Hangul is currently being developed.

The method to be described below is a description of the currently developed ATTACH CODE (National Standard No. KICS.KO-05.0018).

1 is an exemplary diagram of a ATTACH CODE.

Referring to FIG. 1, two consonants and vowels are arranged for each button interval on the horizontal axis of a button between consonants and vowels of Korean characters between button keys for inputting numbers in a telephone. In other words, between buttons '1' and '2' consecutively 'a' and 'b', between buttons '2' and '3' successively 'ㅏ' and 'ㅓ', buttons '4' and '5' Between 's' and 'ㅇ', buttons '5' and '6' between 'ㅗ' and 'TT', between buttons '7' and '8' ', Buttons' 8' and '9' is placed consecutively 'ㅣ' and 'ㅡ'. In the above-described horizontal axis, between '*' and '0' and between '0' and '#' is an empty space. In addition, four consonants and vowels are arranged diagonally on the button. That is, between the buttons '1' and '5', 'ㄷ, ㄹ, ㅂ, ㅁ' is arranged with the consonants clockwise from the diagonal point closest to the button '1', and between the buttons '3' and '5'. For ', ㅔ, ㅐ, ㅑ', place the vowel in the clockwise direction from the diagonal point closest to button '3', and between '4' and '8', place 'ㅈ, ㅈ, ㅐ, ㅋ'. Place the consonants clockwise from the diagonal point closest to the button '4', and between the buttons '6' and '8' place the 'ㅠ, ㅖ, ㅒ, ㅛ' clock from the diagonal point closest to the button '6' Place the vowel in the direction. On the diagonal line, 'ㄲ, ㄸ' is arranged between buttons '7' and '0', and 'ㅉ, ㅆ' is arranged between buttons '9' and '0'. Also, 'ㅃ' is disposed between '0' and '8' only on the vertical axis. After placing the Hangul alphabet as described above, if the user wants to send a letter 'ㄱ' using the telephone, first, find the button closest to the 'AB' among the arranged letters. That is, when the button '1', which is the closest button to the letter 'a' is pressed, and the button '2', which is the closest to the button '1' and the line 'a', is pressed, the expression for the letter 'a' becomes' Completed as 12 '. Also, if the user wants to transmit 'c', first, '1', which is the button closest to 'c' among the arranged letters, is pressed, and then the button closest to the line where the button '1' and 'c' is located. Pressing '5' completes the expression for the character 'c' as '15'. If you write a longer sentence, for example, if you want to send the word 'KT', the user can use the number buttons to 'Han' '872321', 'Station' '126512', 'Tong' '845654' Since ',' God is represented as '458921', when the numbers are pressed at once, 'Korean communication' can be expressed as '872321126512845624458921'.

Another example is described with reference to FIG.

3 is a diagram showing the Hangul alphabet by Han Seung-woo's Handol code.

'A' and 't' and 't' on button 1, 'b' and 't' and 't' on number 2, 't' and 't' and 't' on number 3, ' ㄹ, 'ㅋ' and 'ㅠ', 'ㅁ' and 'ㅌ' and 'ㅗ' at No. 5, 'ㅂ' and 'ㅃ' and 'ㅑ' at No. 6, 'ㅅ' and 'ㅆ' 'And' ㅡ ', number 8' ㅇ 'and' ㄷ 'and' ㅛ ', number 9 and' ㅈ 'and' ㅉ 'and' ㅓ ', number 0 and' ㅎ 'and' ㅣ ' The # button acts as a spare key and 'ㅘ' before typing 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ', 'ㅊ', 'ㅋ', 'ㅌ' and ' When inputting ',' it is used as a compound vowel synthesis key which is input like 'ㅗ # ㅏ', and '*' is used as the end of Hangul input. If you enter '1', you enter '1', 'ㄲ' enters '# 1', and 'ㅐ' enters '3 # 0'. According to the above rules, '906 *' can be entered to enter 'home'.

In the system capable of text communication using the numeric button keys as described above, in the method using the ATTACH CODE, two button values are to be input for each letter, and thus the method proposed by the present invention. The number of inputs is more than 1.4 times per letter, and the Hangul alphabet is placed on all 10 numeric keys, making it difficult to print on the actual numeric keys and difficult to memorize. Considering the current technology situation, it is very difficult to use it in reality, and it is not suitable for memorizing phone numbers for memorizing '7788' like 'cheek width', and the arrangement is very inappropriate for memorizing by the general public. In order for the technology to be practical, the general public had to replace all current telephones. In addition, the method using the handol code is' b 'and' ㅊ ',' ㄹ 'and' ㅋ ',' ㅁ 'and' ㅌ ',' ㅇ 'and' Even if it is printed on the keypad, it is very difficult to get used to the arrangement even if it is printed on one button, so it cannot be used on the phone that is not printed on the keypad. If you enter without a key and enter the next vowel in the vowel vowel, it is easy to confuse the point that you need to press the spare key, and there is a lot of error of typing, and even if you make a phone call that memorizes the phone number in sentences, 'S existing phone calls are not acceptable at all, and the strong resistance of the existing culture is expected, and even if you just make a phone call, you can quickly and 6464, teppanyaki and Like 2818 ', there is no similarity between the phone number and the actual phone number.

The present invention has been made to solve the above problems, an object of the present invention, when the character communication using the button keys of the numeric keypad, unlike the above ATTACH CODE or Handol code, Hangul consonants In terms of layout, '7788' is 'cheek width', '8282' is 'quickly' and '4989' is 'acceptively sold' by accommodating the existing numbers for memorizing phone numbers. By using only one character code, it is possible to transmit texts enough to the existing phones without any text display on the number buttons, and to achieve popularization and simplicity of text communication by the phone.

Hereinafter, with reference to the accompanying drawings for the configuration and operation of the embodiment for achieving the object of the present invention.

Figure 2 is an illustration of the Hangul Jamo arrangement of only one character code of the present invention.

First, referring to FIG. 2, only one character code will be described.

The one-letter code is consonant with '4' for button 4, '7' for button 7, '7' for button 7, '8' for button 8, and button 9 In the phrase 'gu', 'ㄱ' is pronounced and button 0 is pronounced 'Young' and 'ㅇ' is placed in the letter shape. Like this, buttons 4, 7, 8, 9, and 0 are arranged to memorize by themselves without memorizing anyone. Next, button 1 places 'ㅎ' in 'one' pronunciation, button 2 quickly '828' and so on, 'ㄹ', and button 5 'five' in '5'. Buttons 1, 2, and 5 all have Arabic numerals starting with 'ㅇ', but 'ㅇ' is already placed on button 0, so they are read in different ways or placed in a similar phonetic example like 'quickly'. And button 3 can get 'ㅅ' from the pronunciation of 'sam', but 'ㅅ' is already placed on button 4, so 'ㅁ' is placed after 'ㅁ' in 'sam', and the remaining buttons 6 Place a 'j' that is not placed on the button. If you firmly associate button 6 with 'ㅈ', there are many people who know that 6 is called 'juk (strawberry)' in Korean tutu play. In addition, button 2 has 'ㄹ' in place. Actually, since the word in our country rarely starts with 'ㄹ', it is very difficult for people with phone numbers beginning with 2 to make numbers. Reminiscent of 'ni', which is similar to 'li', and also adds 'b' in relation to the two-law rule, to make more choices, and 'ㅂ' is the sound of 'v'. 배치, 버튼, button 5, ㅃ, ㅃ, 되도록, 되도록, 되도록, 소리, ㅆ, ㅉ, etc. Button 8, 'ㅆ' to button 4 and 'ㅉ' to button 6, and 'ㅋ' to button 9 'ㅌ' is placed on button 5 respectively. This arrangement makes it easy for anyone to use once or twice to memorize the array, and how well this array fits with the current commonly used numbers is '7788' which is 'squishy' and '8282' is quickly In addition to 'roar,' '4989' becomes 'buy and sell', '8272' matches 'fast processing' 100%, '1472' means 'Ilji Cheon', '7942' means 'Friends', '8572' Is an example of 'processing right', it can be seen that only about Hangul among four letters is wrong. This shows that people can easily memorize the consonant arrangement of the present invention, and also has the advantage of minimizing the confusion or backlash that comes with applying the new method. In addition, the vowels are arranged in lexical order starting from the number 1, and the vowels 'ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ' are numeric keys '1,2,3,4,5'. , 6, 7, 8, 9, 0 'in order. This array consists of the first four vowels 'ㅏ', 'ㅑ', 'ㅓ' and 'ㅕ' placed above '1', '2', '3' and '4' respectively, and the last two vowels 'ㅡ' And 'ㅣ' are most easily memorized to be placed at '9' and '0' respectively, and 'ㅗ' is naturally arranged on '5' with the same pronunciation. It has the advantage that 'TT' and 'ㅠ' are placed on top of '5', '6', '7', and '8'.

In the above description, a function code other than a character code is described as an example. Since up to four characters are arranged in one key button, '*' and '#' are used as function keys to distinguish them when inputting. '*' Is used to enter a rough sound or old sound, and '#' is used to enter a vowel. The rough sound is a letter made by adding a stroke to the example sound. In other words, the old sound is to overwrite the example sound twice so that '*' is pressed twice. To explain this in more detail, first, if you want to input the character as the representative character of the number among the letters arranged on each number button, not the loud or old sound, just press the corresponding button once. However, the representative character of the button '2' where 'ㄴ' and 'ㄹ' are arranged is 'b' as the alphabetical order. That is, '1' is 'ㅎ', '2' is 'ㄴ', '3' is 'ㅁ', '4' is 'ㅅ', '5' is 'ㄷ', '6' is 'ㅈ', '7' is entered as 'ㅊ', '8' is entered as 'ㅂ', '9' is entered as 'ㄱ' and '0' is entered as 'ㅇ'. You can enter '*' for 'ㅋ', '* 5' for 'ㅌ', '* 8' for 'ㅍ', and '** 9' for '된'. '** 5', 'ㅃ' is '** 8', 'ㅆ' is '** 4', 'ㅉ' is '** 6' and 'ㄹ' is not 'b' The vowel is distinguished from the consonant by adding '#': '즉' is '# 1', 'ㅑ' is '# 2', and 'ㅓ' is '#' 3 ',' ㅕ 'is' # 4 ',' ㅗ 'is' # 5 ',' ㅛ 'is' # 6 ',' TT 'is' # 7 ',' ㅠ 'is' # 8 ',' ㅡ '# 9' and 'ㅣ' press '# 0' The way to input the vowels and the vowels is to enter them one after the other in order of appearance: 'ㄵ' means '26' and 'ㅄ' Becomes '84', 'ㅐ' becomes '# 1 # 0', 'ㅘ' becomes '# 5 # 1', and other special function keys are converted to numeric input mode during Korean input. You can use '*' or '#' to return to the character input mode, use '#' to terminate input, '##' to terminate input, or '***' to delete after one character. When the code system, which conflict with the other control actions are the key features of the above it can be appropriately changed.

For example, the character input by the phone using only one code described above, 'Hong Gil-dong' is' 1 # 50 9 # 0 * 2 5 # 50 ',' Kim Young-hee 'is' 9 # 03 0 # 40 1 # 9 # 0 ',' Cafe 'is' ** 9 # 1 * 8 # 3 # 0 ',' Clear Sky 'is' 3 # 1 * 29 0 # 92 1 # 1 2 # 9 * 2 ',' Afternoon 2 o'clock becomes '0 # 5 1 # 7 * # 2 # 4 # 0'.

In order to perform text communication using only one of the codes described above, a program capable of converting to a character with a number input through a numeric keypad is required. An embodiment of a system equipped with such a program will be described in turn.

First, a description will be given of a phone of the device that can input or receive characters using only one code as follows.

4 is a block diagram of a telephone according to the present invention.

Referring to FIG. 4, a ring detector 10 for detecting a ring signal received by a user, a speaker 15 for outputting a ringing tone detected by the ring detector 10, and a handset for transmitting and receiving a voice of a user 20, a hook-switch unit 25 for switching the switch according to the on / off of the handset 20, a call circuit unit 30 for processing voice signals transmitted and received by the handset 20, and a user Keypad 35 for inputting a number combination when transmitting a phone number and text when making a call, and converts a dialing signal and number combination through the keypad 35 into Dual Tone Multi-Frequency (DTMF) Distinguish between the DTMF generator 40 output to 30 and the signal transmitted by only one character code among the DTMF signals output from the call circuit unit 30, and whether the other party transmits the DTMF signal by one character code. Comparator 45) and only one of the DTMF signals transmitted from the call circuit unit 30 according to the result determined by the comparator 45 decodes the signal transmitted by the text code, converts the signal into a text signal, and outputs it again. The program unit 50, which stores only one character code conversion program to decode the signal by one character code and converts it into a character signal, and the display unit 55 that outputs the character signal output from the program unit 50 to the outside. It is composed.

Referring to Figure 4 the operation of the present invention configured as described above are as follows.

First, the other party makes a call.

When the other party dials to the user side using the telephone using the telephone, the ring detection unit 10 of the user receives a ring signal. The signal received from the ring detection unit 10 causes the user to make a call through the speaker 15. Outputs a ringing tone to indicate that the call has been received. When the incoming call is heard, the user picks up the handset 20 to call the other party through the handset 20, and at the same time the hook switch unit 25 connects the handset 20 and the switch. In the above, the voice transmitted by the user and the voice transmitted by the other party are processed into a voice signal suitable for voice exchange through the call circuit unit 30.

In the above, if the user receives a text message using only one character code, the other party makes a phone call to send a text message and transmits a message to be transmitted by only one text code. When the character 'home' is transmitted, the other party presses' 6 # 08 ', which is the number button corresponding to' home ', and I ##', indicating that the input is completed, in the form of only one character code. That is, the 'house' is expressed as '6 # 08 ##'. The signal output by the expression is a signal transmitted by the comparator 45 in the form of a one-letter code different from the existing signal, and the data is identified by '#' which is the Hangul input mode switcher of the one-letter code of the signal. It is applied to the program unit 50. The program unit 50 converts the numeric signal from the numeric signal into the character signal by using only one character code conversion program and displays the number signal to the user through the display unit 55. If the sender and the receiver's telephone itself are provided with only one character code change program, and both phones communicate as text signals, the program unit 50 of the receiver's telephone does not need to undergo a separate conversion process. The display unit 55 may display the display unit 55.

Second, the user calls directly.

When the user lifts the handset 20 to make a call with the other party, the hook switch unit 25 switches the switch. When switched by the hook switch unit 25, the user inputs the other party's telephone number using the keypad 35. The telephone number input by the keypad 35 is converted into a DTMF signal by the DTMF generator 40. The DTMF signal is connected to the other party through an exchange through the call circuit unit 30. When connected with the other party, the user and the other party delivers the voice through the handset 20, and the call circuit unit 30 processes the voice of the user and the other party as a voice signal suitable for making a call.

When the user sees the action of sending a text using only one character code, the user picks up the handset for text transmission, inputs the user's telephone number through the keypad 35, and connects with the other party's phone. If (in the case of the situation where the other party can not exchange voice over the phone), the user inputs the character to be transmitted using the only one character code to the keypad (35). In the above, if the user wants to transmit a character of 'home', the user presses '##', which is a number button corresponding to 'home' in the form of a single character code, and '##', indicating that the input is completed. Run. That is, the above 'house' is expressed as '6 # 08 ##'. The signal output by the expression is converted into a DTMF signal by the DMF generator 40 and applied to the comparator 45 via the call circuit unit 30. The comparator 45 selects the DTMF signal '6 # 08 ##' as a '#' indicating a Korean character input of the one-character code of the signal, which is a signal transmitted by a format of one-character code different from the existing signal. The data is applied to the program unit 50. The program unit 50 converts the numeric signal from the numeric signal into a character signal by using only one character code conversion program, and outputs it to the counterpart through the hook switch unit 25, and transmits the transmitted character through the display unit 55. Display it to the user to check for typos.

In addition, since the pager currently being used by the general public has a reception device capable of receiving texts, if the user wants to send a text to the pager instead of the other party's phone, the user wants the user's pager through the above process. If you enter a character and send it, the character transmission is completed.

The above process will be described with reference to the flowcharts of FIGS. 5 and 6 as follows.

5 is a flowchart of an operation in the transmission mode of the telephone of FIG.

6 is a flowchart of the operation in the reception mode of the telephone of FIG.

First, referring to FIG. 5, when the transmission mode of the phone is described, the user determines whether to send a text message to the user (S100).

According to the result determined in step S100, if the user does not transmit the text call in the normal phone mode (S200), if you want to send a text, only one character to be transmitted by the character code method through the keypad 35 (S300).

Numerical combination of only one character code input in the process S300 is converted into a character signal by one character code conversion program of the program unit 50 (S400).

The text signal converted in step S400 is transmitted to the counterpart via the hook switch (S500).

6, the user determines whether the other party's phone is a text transmission (L100).

If the text is not transmitted in the process L100 in the normal telephone mode (L200), and in the case of text transmission, the comparator 45 determines whether the text is transmitted by only one character code method (L300).

According to the result determined in the above L300, if only one character transmission is not a number combination signal based on the character code method, the process moves to step L500 to be described later. The character signal is converted into a character signal by the character code conversion program (L400).

The text signal of the counterpart converted into the text signal in L500 is displayed to the user through the display unit 55 (L500).

Through all the above processes, the text communication system of the telephone is implemented as the present invention intends.

As a second embodiment, a character communication system of a pager using only one code will be described.

Referring to FIGS. 7, 8, and 9, FIG. 6 illustrates a ring detector 10 in which a ring signal incoming to a user is detected, and a spur SP for outputting a ringing sound detected by the ring detector 10. ), A handset 20 for transmitting and receiving a user's voice, a call circuit unit 30 for processing voice signals transmitted and received by the handset 20, and switching the switch according to on and off of the handset 20. Hook switching unit 25, the keypad 35 for inputting a telephone number when the user makes a call, and dialing signal and pager number through the keypad 35 is converted into DTMF (Dual Tone Multi-Frequency) It is composed of a DTMF generator 40 for outputting to the call circuit unit (30). 7 shows a DTMF receiver 60 for receiving a DTMF signal output from the telephone, a memory 65 for constructing and storing only one character code conversion program, and a tone signal received by the DTMF receiver 60. In case of transmission by only one character code, the decoder 70 outputs character information corresponding to each number stored in the memory unit 65 and decodes only one character code into a Hangul code for character transmission, and the decoder 70. RF generator 75 for generating a high frequency for transmitting a signal including the character information output from the radio and amplified high frequency signal generated by the RF generator 75 to transmit the pager antenna 85 It consists of an RF transmitter 60 for transmitting through. 8 shows a receiving antenna 90 for receiving a high frequency signal transmitted from the transmitting antenna 85, an RF receiving unit 95 for demodulating a high frequency signal received at the receiving antenna 90, and the RF receiving unit 95. Waveform shaping unit 100 for converting the demodulated analog signal to a digital signal, a decoder 70 for decoding the information converted by the waveform shaping unit 100 to the digital signal, and the unique data of the radio call receiver A microprocessor 110 for storing the ROM 105 and the received data into the decoder 70 to compare and discriminate the data with the ROM 105, and output magnetic data temporary alarm data and received data; A display unit 55 (LCD: LiquidCristal Display) for displaying the received data under the control of the microprocessor 110 and a call signal for generating a call signal (alarm sound, vibration) under the control of the microprocessor 110. Driving (125), an alarm sound speaker (115) for generating an alarm sound among the call signal, a vibration motor (120) for generating vibration in the call signal, and a call signal driver (125) under the control of the microprocessor (110). ) Is configured as a call signal stop button 120 to turn off the call signal.

The operation of the pager character transmission system using the Hanman character code of the present invention having the above configuration is as follows.

Referring first to the operation of Figure 7, the user lifts up the handset 20 to make a text transmission using the above only one character code to a wireless caller using a telephone. When the handset 20 is lifted, the hook switch unit 25 is operated to be connected to the switchboard, and the user dials the wireless call subscriber through the keypad 35 after confirming the dial tone. The signal dialed through the keypad 35 is converted into a tone signal in the DTMF generator 40 and is connected to the exchange via the call circuit unit 30. The exchange connects with the wireless calling service provider to match the dialing signal. When connected to the wireless call service provider in the above, the user only needs to enter a character that you want to enter to match the format of the character code. For example, if a user wants to send a text of 'home', the user first presses '6 # 08', which corresponds to 'home', and '##', which indicates that the input is completed. That is, the button corresponding to the above 'home' is transmitted as the total '* # 6 # 08 ##'. The text signal transmitted in the above process is transmitted to the pager through the system of the wireless call service provider of FIG. Referring to the operation in FIG. 7, the text signal is received by the DTMF receiver 60, and only one character code representing the 'home' received by the DTMF receiver 60 is applied to the decoder 70. The decoder 70 drives only one character code conversion program stored in the memory unit 65 to decode only one character code of '6 # 08 ##' into a conventional Hangul code for character transmission. The data of '6 # 08 ##' decoded by the decoder 70 is changed to a Hangul code representing 'zip'. The data changed into the Korean code in the decoder 70 is converted into a high frequency signal by the RF generator 75. The high frequency signal generated by the RF generator 75 is amplified by the RF transmitter 80 in an appropriate amount and transmitted to the pager capable of transmitting a character of FIG. 8 through the transmission antenna 85. Referring to the operation in Figure 9, after receiving the RF modulation signal transmitted from the wireless call service provider to the receiving antenna 90, the RF receiving unit 95 demodulates the RF demodulated signal, the demodulated signal waveform After filtering and amplifying by the shaping unit 100, the signal is converted into a digital signal of a binary code so that the signal can be processed by the microprocessor 110 and the decoder 70. Is authorized. The decoder 70 decodes the data carried in the digital signal applied by the waveform shaping unit 100 and applies it to the microprocessor 110. In the method of receiving data by the microprocessor 110, the data is processed using a reception clock having a period determined according to a transmission rate in the form of a code. When the magnetic data is received during the data processing, the received data is then analyzed. In this case, the ROM 105 stores two addresses composed of predetermined address bits and frame data of the radio call receiver. The microprocessor 110 stores the address contained in the ROM 105 in the internal RAM when the initial power is turned on, stores 32 bits of the received address codeword in the RAM, and reads the bits by 4 bits, respectively, in the accumulator. Compare. Also, if the 32-bit data of the message coder is stored in an internal buffer memory and the received data compared by the accumulator turns out to be the same data, self-data (caller's telephone number, voice and text data) is stored in the display unit ( 55) (LCD: Liquid Cristal Display) while driving the call signal driving unit 125 at the same time the call sound through the alarm sound spur 115 or the vibration signal through the vibration motor 120 is output. In the above process, the DTMF signal inputted by the user using the telephone as '6 # 08 ##', which is a one-character code indicating 'home' by one-character code, is converted by one-character code conversion program of the wireless calling service provider. It is changed to a Hangul code representing 'home', and the character 'home' is displayed as the final text signal through the display unit 55 of the pager.

Through all the above processes, the pager character transmission system using only one character code is implemented as the present invention intends.

As a third embodiment of the present invention, when the ARS server shows that the intended ARS service by text communication only one code through the phone as follows.

10 is a block diagram of an ARS (AUDIO RESPONSE SERVICE) server according to the present invention.

Referring to Figure 10,

10 is a program for converting a digital signal converted from an ARS interface unit 135 and an ARS interface unit 135 capable of receiving a DTMF signal from an ARS server, converting it into a digital signal, and outputting a voice, into a single character code. And a memory unit 65 in which an ARS server specific service program is stored and loaded with data when necessary, and a microprocessor 110 capable of processing the program.

Referring to Figure 7, the operation of the present invention configured as described above is as follows.

The user picks up the handset 20 to receive ARS service using the telephone. When the handset 20 is lifted, the hook switch unit 25 is operated to be connected to the switchboard, and the user dials the ARS server through the keypad 35 after confirming the dial tone. The signal dialed through the keypad 35 is converted into a tone signal in the DTMF generator 40 and connected to the exchange via the call circuit unit 30. The exchange connects the ARS server to match the dialing signal. If the system is connected to the ARS server and the system requires character input, the user only needs to enter a character that he wants to input in accordance with the format of the character code. For example, if a user wants to send a character 'home', first press '6 # 08', which corresponds to 'home', in the form of a single character code, and '##', which indicates that the input is completed. . That is, the buttons corresponding to the above 'home' are transmitted as the total '6 # 08 ##'. The text signal transmitted in the above process is accepted by the ARS server of FIG. 10 to provide a voice service. Referring to the operation in FIG. 10, the text signal is received by the ARS interface unit 135 mounted on a server capable of receiving a DTMF signal, and expresses the 'house' received by the ARS interface unit 135. The DTMF signal is converted into a digital signal and applied to the microprocessor 110 of the server. The microprocessor 110 converts the DTMF signal of '6 # 08 ##' into a character of 'home' by driving only one character code conversion program stored in the memory unit 65. Recognizing this, the ARS server services the corresponding voice service through the ARS interface.

As can be seen from the above description, the present invention provides a device for performing only one character code conversion program that can implement the consonants and vowels of the Hangul corresponding to each button value to transmit characters using only the existing numeric keypad buttons; Equipped with a text display window on a specific device, the sender can check the text to be sent when the user wants to send a text using this device, and can also check the contents sent from the other party through the text display window. If the program is built in the system of the wireless call service provider and the user wants to send a text using a telephone, the text is inputted to the keypad by a text code method, and the input text is transmitted to the pager receiver, and the program Built on the ARS server, from the user The effect of receiving the characters, and the one-character code is made to reflect the existing numbers for the existing number memorization, so that you can easily memorize the button key value for each character, you can memorize all the phone numbers in sentences It is effective.
