The text message transmission / reception operation of the SMSC according to the present invention operates in the order of the flowcharts of FIGS. 3 and 4 of the accompanying drawings.

First, when the user turns on the transmitter / receiver 60 while the power of the telephone is turned on, the main processing unit 40 reads the voice data corresponding to the first message stored in the third memory unit 80, / Sign language unit 60. The user listens to the voice guidance "Please use 1 on the touch pad if you want to make a phone call and write 2 if you want a text message" (step S1). When the user writes "1" to the touch pad unit 90 as instructed in the message for telephone conversation, the main processing unit 40 detects the voltage applied from the touch pad unit 90, (Step S2), the voice data corresponding to the second message stored in the third memory unit 80 is read and the voice data corresponding to the second message stored in the third memory unit 80 is read to the user (Step S3). Accordingly, the user writes the telephone number to the touch pad unit 90 according to the guidance of the voice signal outputted as "Write desired telephone number ", and the main processing unit 40 causes the touch pad unit 90 (Step S4) and outputs the recognized telephone number to the modem / tone generator 110. Then, the modem / tone generator 110 (Step S5), and the telephone call can be established by connecting to the other party's telephone through the station selection unit 30 (step S6). After step 1, if the user writes 2 in the touch pad unit 90 to transmit a text message, the main processing unit 40 senses the voltage applied from the touch pad unit 90, Since the character written on the touch pad unit 90 is 2 (step S2), the voice data corresponding to the second message stored in the third memory unit 80 is read And outputs it to the user (step S7). Accordingly, the user writes the telephone number to the touch pad unit 90 according to the guidance of the voice signal that is output as "Write the desired telephone number" through the transmitter / receiver unit 60, and the main processing unit 40 Recognizes the telephone number input through the touch pad unit 90 and stores it in the second memory unit 70 (step S8), reads the voice data corresponding to the third message from the third memory unit 80 (Step S9). The user who listens to the message " write a message to be delivered "writes a message to be transmitted to the other party on the touch pad unit 90. [ The main processing unit 40 recognizes a message written on the touch pad unit 90 according to a conventional character recognition algorithm and converts it into an ASCII (American Standard Code for Information Interchange) The 8-bit or 16-bit binary data generated by converting the code into the complete code based on the Hangul implementation algorithm is stored in the second memory unit 70 (step S10). The main processing unit 40 reads out the telephone number stored in the second memory unit 70 and outputs the read telephone number to the modem / Tone generating unit 110 generates a transmission signal corresponding to the applied telephone number and outputs the generated transmission signal to the station selecting and combining unit 30. The station selecting and combining unit 30 receives the telephone number Side communication medium corresponding to the telephone number (step S12). Thereafter, the main processing unit 40 confirms the type of the reception side communication medium based on the response signal applied from the connected reception side, and confirms whether a predetermined response signal corresponding to the type of the reception side communication terminal device is applied Thereby confirming the type of the communication medium on the receiving side (step S13). At this time, if the receiving side medium is a facsimile machine, it sends a predetermined confirmation signal to the receiving side according to the handshake protocol, and checks whether the receiving side can transmit / receive data, and prepares (Steps S14 and S15), the binary code of the text message stored in the second memory unit 70 is read and converted into the data format of the fax, and the data is transmitted (step S16). When the transmission of the data is completed And ends the operation (step S17). On the other hand, in step S13, if the connected communication medium of the receiving side is a cellular phone or a pager, the main processing unit 40 sends a predetermined confirmation signal to the receiving side through the handshake protocol and checks whether the receiving side can transmit / (Steps S18 and S19), the binary code of the text message stored in the second memory unit 70 is read and converted into packet data, which is a data format of the cellular phone or phaser, (Step S20). When the transmission of the data is completed, the operation is terminated (step S21). In step S13, if the connected communication medium on the receiving side is a modem, the main processing unit 40 sends and receives a predetermined confirmation signal to the receiving side through the handshake protocol to check whether or not the receiving side can transmit / receive data, (Step S22, S23), the binary code of the text message stored in the second memory unit 70 is read and transmitted as serial data (step S24), and the data transmission Upon completion, the operation is terminated (step S25). On the other hand, in the case where the communication medium on the receiving side connected in step S13 is a sphere telephone or a communication medium that does not adopt the message sending / receiving method according to the present invention, or the receiving side can transmit / receive data in the steps S15, S19, Since the data can not be transmitted, the voice data corresponding to the fourth message stored in the third memory unit 80 is read out and output, and the other party has a device which can not receive the character. (Step S30). On the other hand, if the communication medium on the receiving side connected in step S13 is the character transmitting / receiving telephone according to the present invention, the tone signal corresponding to "1" is transmitted to the telephone on the receiving side (step S26) It is a signal to start. The telephone on the reception side checks whether the tone signal corresponding to "1" is applied from the telephone on the transmission side (step S32) When the reception of the data is ready, the tone signal corresponding to "9 " is transmitted to the telephone of the transmission side. The symbol" 9 " When the tone signal corresponding to "9 " is received from the telephone on the reception side (step S27), the main processing unit 40 transmits the text message stored in the second memory unit 70 to the modem / (Step S28), the main processing unit 40 sends out a packet filled with "1 " to the receiving-side telephone set And notifies that the transmission of the text message is completed (step S29). After that, the receiving-side telephone checks whether or not a text message is applied from the telephone at the transmitting end (step S34). When the text message is applied, the receiving-side telephone stores the applied text message in its own second memory unit 70 S35). When all the packets filled with 1 are received, it is recognized that the transmission of the text message from the transmitting telephone is completed (step S36), and the voice data corresponding to the fifth message is read from the third memory 80 If the user wishes to listen to a text message, " Write 2 to the touchpad to see 1 on the LCD "is output (step S37). Accordingly, when the user listens to the voice message and writes 1 or 2 in the touch pad unit 90, the main processing unit 40 recognizes the number applied from the touch pad unit 90 (step S38) (Step S39). When the received message is recognized as 2, the received message is read from the second memory unit 70 and displayed on the LCD display unit 100 (step S39) Step S40), the recipient hears or reads the message. Thereafter, when the output of the received message is completed, the main processing unit 40 of the receiving-side telephone reads the voice data corresponding to the sixth message from the third memory unit 80 and outputs it, Quot; 1 " to write 2 to the touch pad unit 90 "is output (step S41). The user writes 1 or 2 to the touch pad unit 90 in accordance with the voice message (step S42). When the main processing unit 40 recognizes the character applied from the touch pad unit 90 and recognizes it as 1, (Step S43), the voice data corresponding to the seventh message is read from the third memory unit 80, and the voice data is read from the speaker SP) (step S44). Thus, the user hears the voice guidance "Message has been deleted" and recognizes that the message has been deleted.
