CID telephone having an automatic transmission function of SMS and controlling method therefore}

The present invention relates to a CID telephone with a short message automatic transmission function and a control method thereof. In particular, the present invention includes a DSP means for retrieving CID information, and searches for the presence of a number designated by the user when the CID information is input. The present invention relates to a CID telephone having a short message automatic transmission function for transmitting a user's message, if any, 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 FIG. 1, a telephone system equipped with a conventional SMS function as described above, an interface unit 72 for interfacing a call signal of an external caller transmitted from an exchange system 71 via a PSTN network 70 is described. And a microcomputer 74 which controls the overall function of the telephone system 73, including the function of the interface unit 72, and the short messages SMS inputted in the absence of the user through the interface unit 72. And a memory unit 75 for storing according to the function control signal of the microcomputer 74 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.

On the other hand, referring to the operation of the telephone system equipped with the conventional SMS function as described above, first, when the telephone system 73 is set up, the microcomputer 74 in the standby state or the function setting signal of the key panel unit 77 It is determined whether or not a ring signal is input. 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 this short message through the interface unit 72 and stores it 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. In addition, when the short message reservation transmission function is set in the phone 73, the microcomputer 74 stores the short message and the reservation time input from the user, and then continuously checks the reservation time. Then, the microcomputer 74 sends a short message to the destination telephone number when the current time reaches the reservation time set by the user.

However, the conventional phone equipped with the SMS function as described above can not only store or display a short message but transmit a message of each individual content to various parties, and also, the reservation sending function of the short message is also reserved at the time of reservation. Since it is absolutely affected, even if the terminal is outage at the set reservation time, even if it is restored later, the original set reservation function cannot be restored, thereby significantly reducing the functionality of the phone.

Therefore, the present invention has been invented to solve the above-mentioned conventional problems, and has a DSP means for searching CID information. By sending a message, the message is automatically sent to a specified phone number regardless of the user's absence or setting time, thereby providing a CID telephone equipped with a short message automatic transmission function that maximizes the convenience of the telephone and its control method. There is a purpose.

Another object of the present invention is to provide a CID telephone with a short message automatic transmission function and a control method thereof, which can record and transmit various contents of a message according to a designated telephone number, thereby significantly improving the functionality of the telephone.

The present invention for achieving the above object is a DSP unit for demodulating and demodulating the CID information input and output through the PSTN network to the FSK method and for storing a specific telephone number for the transmission of a specific message specified by the user, and the individual telephone stored in the DSP A microcomputer that individually transmits a specific message set by the user according to the result by comparing the numbers with the received CID information, and a short message for each telephone number input by the user according to the individual transmission control signal of the microcomputer. The present invention provides a CID telephone having a short message automatic transmission function including a memory unit for storing voice messages.

Another feature of the present invention is an individual message creation step of creating and storing an individual phone number and a specific message signal for each individual phone number in the telephone system, and when a ring signal is input and hooked off for a predetermined time after the individual message creation step. An individual phone number verification step of confirming whether or not the telephone number currently called corresponds to a specific phone number designated by the user, and confirming that the telephone number currently called by the individual phone number verification step is not a specific phone number designated by the user. In this case, a general missed message transmission step of transmitting a general missed announcement message to a caller who is currently calling and receiving and storing a response message, and a specific phone number designated by the user by the phone number currently called by the individual phone number verification step Specific phone number specified by the user if It provides a control method of a CID telephone with a short message automatic transmission function consisting of a specific message transmission step of transmitting a specific message corresponding to the user of the telephone number.

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 of an external caller transmitted from an exchange 2 via a PSTN network 1, and inputted through the interface unit 3; Ring signal processing unit 4 for detecting a ring signal in the call signal and ringing an alarm sound, and call signal processing unit 5 for converting / demodulating and amplifying a call signal input / output through the interface unit 3. And a DSP unit 6 for demodulating and demodulating the CID information input and output through the interface unit 1 using the FSK method and storing individual telephone numbers for transmission of a specific message designated by the user, and stored in the DSP 6. The microcomputer 8 transmits a specific message set by the user individually according to the result of comparison with the individual phone numbers and the received CID information, and controls the functions of the phone 7 as a whole. Individual transmission control According to a call and a memory unit 9 for storing the short message (SMS) or a voice message by an individual telephone number entered by the user.

One end of the microcomputer 8 is connected with a key panel unit 10 for inputting a user's control command signal or dialing signal, and the other end of the microcomputer 8 has a short sentence of the memory unit 9. An LCD 11 for reproducing a message 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 to the individual message creation step (S2) in the initial state (S1) as shown in Figure 3 to create and store the individual phone number and the specific message signal for each individual phone number. When a ring signal is input after the individual message composition 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 on, proceeds to the general call function execution step (S4) to execute the general call function.

That is, when the user sets the individual phone number message setting function through the key panel unit 10 on the phone 7, the microcomputer 8 recognizes this function and switches to the individual phone number specific message mode on the LCD 11. Display. Then, the user of the telephone 7 inputs the telephone number which he / she wants to leave a specific message and inputs an individual specific message corresponding to the telephone number as a short message or a voice signal. At this time, the microcomputer 8 stores individual telephone numbers set by the user in the DSP unit 6 and stores specific messages for individual telephone numbers, for example, short messages or voice messages in the memory unit 9.

Here, if the ring signal is input to the ring signal processor 4 through the PSTN network 1 and the interface unit 3, the ring signal processor 4 notifies the microcomputer 8 of the ring signal. 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 exchange 2 through the PSTN network 1 to make a call. 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. In this case, the microcomputer 8 performs FSK demodulation through the DSP unit 6 to display the CID information input through the interface unit 3 on the LCD 11.

On the other hand, if it is determined during the call mode determination step (S3) that if the phone is hooked off for a predetermined time proceeds to the individual phone number determination step (S5) and the current phone number is consistent with the specific phone number specified by the user Judge. At this time, if the individual telephone number determination step (S5) is determined as the current telephone number is not a specific telephone number specified by the user proceeds to the general missed message transmission step (S6) and the general missed guidance message to the caller currently called. It transmits and receives and stores a response message if there is one.

However, when the individual telephone number determination step (S5) determines that the currently called telephone number matches the specific telephone number specified by the user, the process proceeds to the specific message sending step (S7) and corresponds to the specific telephone number designated by the user. Send a specific message to the user of the phone number.

That is, the microcomputer 8 of the telephone 7 performs FSK demodulation through the DSP unit 6 and displays the CID information transmitted from the called telephone 14 on the LCD 11. At this time, if 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 demodulates and reads the current through the DSP unit 6. The CID information of one telephone 14 and the individual telephone numbers previously stored in the DSP unit 6 are compared one by one. Here, the microcomputer 8 sends a general missed message stored in the memory unit 9 when the telephone number of the telephone 14 currently called does not match any of the individual telephone numbers stored in the DSP unit 6. Transfer to the other party's phone 14.

However, the microcomputer 8, if the telephone number of the telephone 14, which is currently called, matches any one of the individual telephone numbers stored in the DSP unit 6, the memory unit 9 for a specific message corresponding to the telephone number. ) To send to the specific phone number currently called. At this time, if the specific message is a voice signal, the microcomputer 8 converts the analog signal through the DSP unit 6 and transmits it through the interface unit 3, and in the case of a short message, modulates the FSK.

Therefore, according to the present invention, when a call signal is input from a specific telephone number set regardless of a message sending time, an individual message having a specific content can be transmitted.

As described above, the present invention includes a DSP means for retrieving CID information, searches for the number specified by the user when inputting the CID information, and transmits the user's message when there is a corresponding telephone, thereby preventing the user from being set up. Since the message is automatically sent to the designated phone number regardless of time, it has the advantage of maximizing the convenience of the phone accordingly.

Another object of the present invention is to provide a CID telephone with a short message automatic transmission function and a control method thereof, which can record and transmit various contents of a message according to a designated telephone number, thereby significantly improving the functionality of the telephone.
