The present invention relates to a wired / wireless telephone for transmitting and receiving a text message and a missed answering method thereof. In particular, the present invention relates to a text message answering function for guiding a user's absence by using a text message for a telephone received at a landline telephone terminal in the absence of the user. The present invention relates to a wired / wireless telephone having a control method and a control method thereof.

Recently, our country has implemented a Calling Identification Display (CID) service to prevent mischief calls, obscene calls and violent calls or to check incoming calls while users are away. The caller information service refers to a service that informs the receiver of the caller's telephone number and name before the receiver answers the call by using the display device of the communication terminal. Calling party information service is currently provided not only in public switched telephone networks (PSTNs) but also in mobile communication networks.

The caller information provided by the public telephone network is provided by the local exchange to the receiving terminal when a call connection is requested from the sending wire / wireless telephone to the receiving wire / wireless telephone. The national exchange transmits the sender information between the first incoming ring signal and the second incoming ring signal to the receiving terminal, where the calling party information is transmitted to the receiving terminal in a frequency shift keying (FSK) manner. Accordingly, the receiving terminal displays the caller information including the caller's name, telephone number, and telephone time.

On the other hand, among the recently developed wired and wireless telephones, there is a wired and wireless telephone (SMS telephone) having a text message transmission and reception capability. Text message transmission and reception was originally provided only in a mobile communication service, and as the number of users using the text message function increases, it is possible to send and receive text messages through general wired and wireless telephones.

However, when a telephone is received in a wired / wireless telephone capable of transmitting and receiving a text message when the user is absent, there is a problem in that the other party cannot be notified of the absence of the user. Therefore, in order to inform the absence of the user, there is a problem such as additionally installing a voice response function in a wired or wireless telephone capable of transmitting and receiving text messages.

The present invention has been made to solve the above problems, and provides a wired / wireless telephone having a text message answering function for guiding the user's absence by using a text message to the incoming call in the absence of the user and its control method There is a purpose.

In order to achieve the above object, there is provided a wired / wireless telephone having a text message response function and a control method thereof, including: storing a missed message for guiding a user's absence in the form of a text message; Determining whether to receive caller information from the outside when the user is switched to the missed mode according to the user's selection; Checking the caller's telephone number included in the caller information when the caller information is received; And sending the missed message to the caller's phone number.

Here, when switched to the missed mode, the step of entering the ready state to automatically send the missed message; Extracting only the phone number information of the caller from the caller information and adding it to the format of the missed message; It is possible to include the step of automatically sending the missed message to the caller's telephone number by occupying the call of the incoming call.

On the other hand, according to another field of the present invention, in the wired / wireless telephone having a key input unit for inputting letters and numbers, a jack for trunk line connection, and a handset for voice call, the key input unit A text message storage unit for storing an absence message for guiding a created user's absence; An FSK signal processor for receiving caller information (CID) of a frequency shift keying (FSK) input through the jack and transmitting the missed message to the FSK; And a control unit for extracting the caller's telephone number included in the caller information through the FSK signal processor and sending the missed message to the caller's telephone number when the user is switched to the missed mode according to the user's selection. It is also achieved by a wired or wireless telephone which transmits and receives text messages.

The control unit may be configured to load the missed message stored in the text message storage unit into the missed mode and add the extracted caller's phone number to a format of the missed message. It is most desirable to control the missed message to be automatically sent to the caller's telephone number by occupying the call.

Hereinafter, a wired / wireless telephone having a text message response function and a control method thereof according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a control block diagram of a wired / wireless telephone having a text message response function according to the present invention. As shown in FIG. 1, the wired / wireless telephone includes a key input unit 12 for inputting letters and numbers, a display unit, a jack 3 for trunk line connection, and a text message storage unit for storing text messages ( 16), a handset unit 10 including a FSK signal processor 18 for converting a stored message, a microphone 7 and a speaker 5 for voice call, and a key input unit 12 If the text message is stored in the message storage unit 16 and the caller information (CID) is received through the jack (3) connected to the telephone line (1), the text message storage unit 16 to the corresponding phone number It includes a control unit 20 for sending a text message stored in.

The key input unit 12 includes a character key for text input and a telephone call with a numeric key to provide the control unit 20 with a key input signal different from a user's key selection.

Under the control of the control unit 20, the display unit displays a result according to a user's key input, and displays caller information (CID) and text messages received through the telephone line 1, and various types of phone calls. Display information.

The control unit 20 displays the caller information (CID) received through the telephone line (1) on the display unit 14, while the voice signal of the caller received through the telephone line (1) of the handset 10 The user's voice transmitted through the speaker 5 or input to the microphone 7 is transmitted to the telephone line 1 through the jack 3 to enable the use of the telephone call function.

Meanwhile, the message storage unit 16 stores the missed notification message created by the user by using a text key of the key input unit 12 under the control of the control unit 20. In this case, the absent message should include the user's absence time, the reason for the absence, the telephone number to be called, etc., and should be written within 400bytes according to the short message (SMS) standard of Korea Telecom. As the message storage unit 16 in which the missed message is stored, it is most preferable to apply an EEPROM that is free to read / write.

The FSK signal processor 18 may not only receive caller information (CID) received in the form of an FSK signal, but also generate and send an FSK signal according to a text message stored in the message storage unit 16. Here, the FSK modulation / demodulation frequency is the same as the frequency of the caller information (CID) signal. That is, the FSK signal processing unit 18 modulates the text message input by the user into the FSK signal so that the FSK signal processing unit 18 can be provided to the other party through the telephone line 1.

Herein, the control unit 20 stores the text message input by the user through the key input unit 12 in the message storage unit 16, and when the user is switched to the missed mode by receiving the caller information (CID). The user's text message stored in the message storage unit 16 is processed through the FSK signal processing unit 18 and transmitted to the caller's telephone number.

The control unit 20 stores the missed message created and edited by the user through the key input unit 12 in the message storage unit 16, and when the user selects the out of office mode when the user goes out, the absent stored in the message storage unit 16. The message is read into a memory (not shown) in the control unit 20 and is ready to automatically send a message.

At this time, when the caller information (CID) is received through the telephone line (1), the control unit 20 extracts only the phone number information of the caller information (CID) to add to the format of the missed message stored in the internal memory (not shown) Thus, the missed message can be sent immediately upon receipt of the caller information CID. In order to send the message, the control unit 20 occupies the call of the incoming call, and after the call is occupied, the message is automatically sent to the received caller's phone number.

The missed response method of the wired / wireless telephone for transmitting and receiving text messages according to the present invention having such a configuration is the same as the flowchart of FIG. 2. First, the user creates and stores an arbitrary missed message in the wired or wireless telephone (S10). The user selects the missed mode when going out and sets the text message to be answered (S12). Here, the control unit 20 of the wired / wireless phone reads the missed message stored in the message storage unit 16 into a memory (not shown) stored in the message storage unit 16 at the same time as the user selects the missed mode and prepares to automatically send a message. Plunge and maintain the standby state (S14).

The control unit 20 continuously monitors whether caller information CID is received through the jack 3 connected to the telephone line 1 (S16).

When the caller information (CID) is received according to the call setting request of the predetermined caller, the control unit 20 extracts the other party's telephone number information included in the caller information (CID) (S18), and the extracted caller's phone number is the control unit ( 20 is added to the format of the missed message stored in the internal memory (not shown).

In order to send the message, the controller 20 occupies the call of the incoming call (S20), and sends the missed message input by the user to the caller in the FSK method (S22).

When the transmission of the missed message is completed, the control unit 20 maintains the standby state again (S24), and continuously monitors whether caller information (CID) has been received.

As described above, the present invention creates, edits and stores a text message indicating a user's absence in a wired / wireless telephone that transmits and receives a text message, and when the phone is set to the missed mode, when the caller information is received from a public telephone network, the caller is called. Prompts the user to send an out-of-office message created by the user as a text message.

Accordingly, the wired / wireless telephone which transmits and receives text messages can be notified to the caller by text message without additionally providing an automatic answering function. Such an embodiment according to the present invention is not limited to the above. However, various modifications can be made within the scope apparent to those skilled in the art in connection with the present invention.

According to the wired / wireless telephone having a text message answering function and a control method thereof according to the present invention as described above, a text message for notifying a user's absence is created, edited and stored in a wired / wireless telephone that transmits and receives a text message, and is stored in the absence of the user.
