The present invention relates to a telephone system with a missed call information transmission function and a control method thereof. In particular, the present invention has a DSP means for retrieving CID information and a short message. The present invention relates to a telephone system having a missed call information transmission function for searching whether a designated number exists and transmitting the received message information when there is a set telephone number, and a control method thereof.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In addition, in such a network, a telephone system is usually used through an exchange to exchange information converted into an electric signal with a counterpart.

However, such a conventional telephone system has recently been used to store and send an out-of-office guide message when a user is absent and to receive and store a short message service (SMS) transmitted from the caller.

Then, referring to the conventional telephone system as described above with reference to Figure 1, the interface unit 72 for interfacing the call signal of the external caller transmitted from the switch system 71 via the PSTN network 70, and the interface unit The microcomputer 74 controls the overall functions of the telephone system 73, including the functions of the 72, and the short messages SMSs inputted in the absence of the user through the interface unit 72. And a memory unit 75 for storing in response to the function control signal or storing the missed guidance message, and an LCD 76 for reproducing the short message signal of the memory unit 75 as a display signal.

In addition, a keypad 77 for inputting a user's control command signal or a dialing signal is connected to one end of the microcomputer 74.

Judge. At this time, if the hook-off signal is not input even after a predetermined time has elapsed after the ring signal is input, the microcomputer 74 proceeds to the user missed mode and the user misses the guide message stored in the memory unit 75 in advance. Is transmitted to the other party's telephone 78. At this time, if there is a short message from the counterpart phone 78, the exchange 71 processes the predetermined signal and transmits it to the phone 73. Then, the microcomputer 74 of the telephone 73 receives the short message through the interface unit 72, processes the short message through the data processing unit (not shown), and stores the short message in the memory unit 75. Then, when the user wants to see the short message stored in the memory unit 75 through the keypad unit 77, the microcomputer 74 displays the short message desired by the user on the LCD 76.

However, the conventional telephone system as described above does not have a means to properly notify the user when an urgent message is received in the absence of the user, so the emergency message is not provided unless the user moves directly to the place where the telephone is located. There is no way to confirm accordingly has a problem that significantly reduces the ease of use of the SMS phone.

Therefore, the present invention has been invented to solve the above-mentioned general problems, and has a DSP means for searching CID information and a short message, and if there is a number designated by the user when the CID information and the short message are inputted while absent. If there is a phone number set by searching and transmitting the received message information, the message is automatically sent to the specified phone number regardless of the user's absence or set time, so the missed call information transmission function that maximizes the functionality of the phone accordingly It is an object of the present invention to provide a telephone system and a method of controlling the same.

Another object of the present invention is to accurately receive a CID signal or a short message that is urgently missed by a specified telephone number, so that the contents of the message can be checked, thereby providing a missed outgoing information transmission function that significantly improves the usability of the terminal. It is to provide a system and a control method thereof.

The present invention for achieving the above object is a DSP unit for demodulating and demodulating the CID signal and short message input and output via the PSTN network to the FSK method and for storing the telephone number for the transmission of the missed message specified by the user, the telephone user A missed call information transmitting function including a microcomputer controlling a function of transmitting a message signal currently received to a telephone number set in the DSP unit in the absence of a message, and a memory unit storing a received message according to the information transmission control signal of the microcomputer; Provides a telephone system.

Another feature of the present invention is to set a missed transmission telephone number setting step of designating and storing a telephone number to receive a message signal received during the absence in the telephone system, and confirms that the user is absent if a message is received after the missed transmission telephone number setting step And a transfer telephone number search step of searching whether the user has set a phone number to be contacted when the user is missed by the user absence checking step and the user absence checking step. When the user is confirmed that the telephone number to be missed by the user is not set in the telephone system, the general missed message transmission step of transmitting a general missed announcement message to the current caller and receiving and storing a response message, if there is; According to the transmission telephone number search step When the user is confirmed that the telephone number to be contacted during the absence is set in the telephone system control method of the telephone system with the missed call information transmission function consisting of a message sending step of transmitting a message received to the telephone number specified by the user to provide.

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

As shown in FIG. 2, the present invention provides an interface unit 3 for interfacing a call signal, a CID signal, and a short message of an external caller transmitted from the exchange 2 via the PSTN network 1, and the interface unit ( 3) Ring signal processing unit 4 for detecting a ring signal from the call signal input through 3) and ringing an alarm sound, and call signal input / output through the interface unit 3, such as modulation / demodulation and amplification. DSP unit for demodulating and demodulating CID information or short message (SMS) inputted and outputted through the interface unit 1 by FSK method and storing individual telephone numbers for transmission of missed messages specified by a user. (6) compares the individual phone numbers stored in the DSP unit 6 with the received CID information, and transmits the received message information to the corresponding phone according to the result and controls the overall function of the telephone 7. Microcomputer (8 And a memory unit 9 for storing the received short message SMS in accordance with the information transmission control signal of the microcomputer 8.

One end of the microcomputer 8 is connected to a keypad 10 for inputting a user's control command signal or dialing signal, and the other end of the microcomputer 8 is a short message of the memory 9. An LCD 11 for reproducing a signal as a display signal is connected, and a handset 12 is connected to one end of the call signal processor 5.

Next, a control method of the telephone of the present invention as described above will be described.

The present invention proceeds from the initial state (S1) to the missed transmission telephone number setting step (S2), as shown in Figure 3 to specify and store the telephone number to receive the message signal received during the absence. When a ring signal is input after the missed transmission telephone number setting step S2, the process proceeds to the call mode determination step S3 to determine whether the current phone is hooked off. At this time, as a result of the determination in the call mode determination step (S3), if the phone is hooked off, proceeds to the general call function execution step (S4) to execute the general call function.

That is, when a ring signal is input to the ring signal processing unit 4 through the PSTN network 1 and the interface unit 3, the ring signal processing unit 4 informs the microcomputer 8 of this. Then, the microcomputer 8 executes the call mode. At this time, when the user hooks up, the interface unit 3 interfaces the call signal transmitted from the switchboard 2 through the PSTN network 1. Input to the signal processor 5. Then, the call signal processor 5 processes the input call signal through a predetermined signal and emits it through the handset 12. When the user makes a call with the handset 12, the call signal is processed through the call signal processor 5 and then the external telephone 13 is transmitted via the interface unit 3 and the PSTN network 1. ) To execute normal call function.

Here, when the CID information is input through the interface unit 3, the microcomputer 8 performs FSK demodulation through the DSP unit 6 to display the CID signal on the LCD 11.

On the other hand, if it is determined during the call mode determination step (S3) that the phone is hooked off for a certain time, that is, if it is determined that the user is absent, the process proceeds to the transmission telephone number search step (S5) and the current user is not in touch Search for a phone number. At this time, if the telephone number to be contacted in the absence of the user is determined during the transmission telephone number search step (S5) is not set in the telephone system, the general missed message transmission step (S6) proceeds to the general missed guidance message to the caller currently called Send and receive and store a response message if there is one.

However, if it is determined during the transmission telephone number search step (S5) that the telephone number to be contacted by the user is set in the telephone system, the message transmission step (S7) is carried out to transmit the received message to the telephone number specified by the user. do.

That is, the telephone system 7 of the present invention first sets the outgoing setting menu through the keypad unit 10 on the LCD 11, and then the telephone number to be contacted by the user in his absence, for example, a telephone of a mobile phone or a general telephone. Set the number. The microcomputer 8 of the telephone 7 then stores it in the DSP unit 6.

At this time, the microcomputer 8 of the SMS phone 7 receives the microcomputer 8 of the phone 7 when a data signal is input from the PSMSC server 14 or the CID block of the external exchange system 2 through the PSTN network. The CID information or SMS data transmitted from the called telephone 13 is displayed on the LCD 11 by FSK demodulation through the DSP unit 6 and simultaneously converted into a digital signal and stored in the memory unit 9. In this case, the microcomputer 8 separates only the sender information such as the email address, the telephone number, the sender's name, the name of the advertisement company of the sender of the message, and stores it in the area of the memory unit 9 designated as the address book area.

At this time, when the hook-off signal is not input even though the ring signal detected through the ring signal processing unit 4 has passed a predetermined number of times, the microcomputer 8 contacts the DSP unit 6 in its absence. The telephone number to be received is searched for, for example, whether a telephone number of a mobile phone or a general telephone is set. The microcomputer 8 transmits the missed message stored in the memory unit 9 to the counterpart when the user has not set a phone number to be contacted in his absence in the DSP unit 6.

However, if the user has set a phone number to be contacted in his absence in the DSP unit 6, the microcomputer 8 reads the phone number stored in the DSP unit 6 and calls the corresponding phone number. Sends the currently received CID information or short message to the phone number.

As described above, the present invention has a DSP means for retrieving CID information and a short message, and if there is a telephone number set by searching for the number specified by the user when the CID information and the short message are inputted when the user is absent, By transmitting the received message information, the message is automatically transmitted to the designated phone number regardless of the user's absence or the set time, thereby having the advantage of maximizing the functionality of the phone.

In addition, according to the present invention, since the CID signal or short message urgently called in the absence can be correctly received by the designated telephone number, the contents of the message can be confirmed, and therefore, the convenience of use of the telephone is also significantly improved.
