Description

A phone has function of calling identity delivery and auto dial}

The present invention relates to a terminal having a caller ID and an autodial function, which receives a caller ID service of a telephone company, displays the caller's information, and automatically sends a confirmation call to the user's telephone number to enable the use of a prepaid card. It relates to a terminal having a display and an autodial function.

In general, a caller display function refers to a function of receiving caller information from a phone station by using a caller display service serviced by a phone station and displaying caller information on a display window of the terminal. The receiver determines the presence or absence of a call by looking at the caller information on the terminal display window.

In addition, the auto-dial function is a telephone bill prepaid service that is authorized by the telephone company to charge the phone charges to the card, and that the calculated charge is deducted by the telephone company for each phone call from the charged card charge.

Conventional terminals do not have the above functions, so in order to receive the above functions, there is a inconvenience in that a device having each function must be connected to the terminal and used. In addition, since there is no device having the above two functions, each device has to be connected in series with the terminal, so it takes up a lot of installation space and becomes complicated.

In recent years, terminals having the above functions have been developed, but they also adopt only one of the above functions. In order to receive all of the above functions, there was an inconvenience of using a device having a function that does not exist in the terminal. .

The present invention focuses on the above-mentioned inconvenience, and configures the caller ID function and the auto dial function in one terminal, and when the user makes a call, the user uses the prepaid card to make a call and receives a call. The present invention provides a terminal having a caller display and an autodial function that allows a caller to receive a call after confirming the caller in advance by the caller display function.

The present invention is connected to a public telecommunication network to generate a tone detector for detecting DTMF signals, a ring detector for generating ring signals, a data receiver for receiving caller information, a hook detector for detecting on-hook and off-hook, and a DTMF signal. An input for inputting a tone generator and a function command to be input, a display for displaying information, a data storage for storing caller information and a telephone number, a data memory for storing temporary data and a program memory for storing program codes, It is comprised by the control part which commands a control.

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

1 is a block diagram of a terminal according to the present invention, a terminal of the present invention is connected to a line of a public communication network to detect a DTMF signal on a line and transmits its value, and a square wave when a ring signal is received Ring detector (2) that generates a signal, a data receiver (3) for receiving caller information from a public telecommunication network, and a hook that senses a voltage changing according to on or off or generates a current telephone line state as a signal A detector 4, a tone generator 5 for generating a DTMF signal, an input unit 6 for receiving a function command, and a display unit 7 for displaying desired information in a picture or text using a graphic LCD. A data storage unit 8 for storing a telephone number or caller information, a data memory 9 for storing temporary data when the program is executed, and a program memory for storing program codes ( 10) and a control unit 11 for controlling them.

The software used in the present invention is largely composed of a caller display function and an automatic dial function, which is performed by the control unit 11 by the state of the telephone line.

2 is a flowchart in which the caller display function is applied when receiving through the terminal of the present invention, and initializes the variables of the data memory 9 (step 101). It is checked whether the hook detector 4 is on (step 102). If the hook detector 4 is in the on state in step 102, the on-hook state is displayed on the LCD of the display unit 7, and the data receiving unit 3 waits for the reception of the FSK data (step 103). If the hook detector 4 is turned off in step 102, the caller's information may come through the public communication network even during a call, and when the call is detected, the CAS signal always comes before the FSK data so that the data receiver may detect 3) waits for the reception of the CAS signal, and displays the off-hook state on the LCD of the display unit 7 (step 104). Following step 104, it is checked whether the DTMF signal is detected by the tone detector 1 (step 105). When the DTMF signal is detected in the step 105, the auto-dial function to be described later is performed, and then the process moves to the step 102 (step 106). Following the steps 103 and 105, it is checked whether the public communication network is connected (step 107). If the public telecommunication network is not connected in step 107, go to step 101. If the public telecommunication network is connected in step 107, it is checked how many times the key is pressed through the input unit 6 (step 108). If the first key is pressed in step 108, all received caller information in the data storage unit 8 is deleted (step 109). If the number 2 key is pressed in step 108, the caller who is currently displayed on the display unit 7 is called (step 110). If the number 3 key is pressed in the step 108, caller information prior to the caller information currently displayed on the current display unit 7 among the received caller information in the data storage unit 8 is displayed on the display unit 7 ( Step 111). If the number 4 key is pressed in the step 108, all the caller information after the caller information displayed on the current display unit 7 among the received caller information in the data storage unit 8 is displayed on the display unit 7. (Step 112). If the fifth key is pressed in step 108, the caller information currently displayed on the display unit 7 is deleted from the data storage unit 8 (step 113). When the steps 109, 110, 111, 112, and 113 are completed, the process moves to step 102.

FIG. 3 is a flowchart illustrating processing when each situation independent of the flowchart of FIG. 2 occurs, and using the interrupt function of the control unit 11, it is checked what state the terminal is in now (201). If the new FSK data is received by the data receiving unit 3 in the step 201, the data receiving unit 3 receives the FSK data, and when the reception is completed, the control unit 11 updates the time and date and then displays the display unit ( The currently received data, time and date are displayed on the LCD of step 7) (step 202). If on-hook or off-hook change occurs in step 201, the control unit 11 receives a signal from the hook detector 4 and displays the current hook state on the LCD of the display unit 7 (step 203). . When the CAS signal is detected in step 201, the DSK signal of the DTMF signal generated by the tone generator 5 is transmitted to the public communication network for 60 ms, and then FSK data, which is the caller information sent from the public communication network, is transmitted. The data receiver 3 is placed in a waiting state for reception (step 204). When the steps 202, 203, and 204 are completed, the process returns to the execution of the main program.

4 is a flowchart in which an automatic dial function is applied when making a phone call to the terminal of the present invention. Check (step 301). If it is not in the automatic mode, it is checked whether the user input number is a toll-free or toll-free number rather than a prepaid card (step 302). In the automatic mode in step 301, the control unit 11 transmits the setting access number stored in the data storage unit 8 that can recognize whether the prepaid card is recognized in the public communication network through the tone generator 5 ( Step 303). The user input number is then checked whether the toll-free or toll-free number is the use of a prepaid card (step 304). If the prepaid card usable number is input in step 302, the prepaid card usable access number is sent out via the tone generator 5 (step 305). Following the steps 304 and 305, the user input telephone number is temporarily stored in the data memory 9 (step 306). Then, it is checked whether the number 1 prepaid card is selected (step 307). If the first card is selected, the corresponding card number is sent out via the tone generator 5 (step 308). If the first card is not selected, the card number of the second card is sent out via the tone generator 5 (step 309). When the card number is sent out in the steps 308 and 309, the user input number stored in the step 306 is read out from the data memory 9 and transmitted through the tone generator 5 (step 310). When the user input telephone number is a toll free or toll free number in steps 302 and 304, the user input telephone number is transmitted through the tone generator 5 (steps 311 and 312). Subsequent to the steps 310, 311 and 312, a call connection is made through a public communication network to make a call (step 313).
