Description

How to automatically connect phone by specifying phone number

The present invention relates to a method of automatically connecting a telephone by pre-designating a telephone number. In a telephone to which a caller ID service is applied, a telephone number of a designated counterpart telephone number and a location to which the user is to be moved should be moved when waiting for an urgent call. When inputted, the present invention relates to a method for automatically connecting a phone by pre-designating a phone number that provides a service for automatically connecting (exchanging) a predetermined phone number when a call is received from the phone number.

1 shows a conventional telephone, a hook switch 1 connecting a telephone line, a voice circuit unit 2 for transmitting and receiving a transmission voice signal and a reception voice signal, and a ring circuit unit for generating a ring signal ( 3), a dial circuit portion 4 for generating and transmitting a dial signal, a keypad 5 for pressing the dial, and a receiver 6 for sending and receiving a voice signal through the voice circuit portion 2. .

Referring to the operation of the conventional telephone configured as described above, when a call signal is received through the line, the ring circuit unit 3 generates a ring signal to inform the receiver that the call has been received through the speaker 7. At this time, when the receiver lifts the handset 6, the hook switch 1 is connected, and the telephone line is connected to the voice circuit unit 2. After the above operation, the voice signal is modulated into an electrical signal through the handset 6 and sent to the voice circuit unit 2, and the electric signal received from the voice circuit unit 2 is modulated into a voice signal by the receiver 6 You can talk to the phone.

On the other hand, if you lift the handset 6 first to make a call, the hook switch 1 is turned on and the telephone line is connected. When the operation is completed and the dial key of the keypad 5 is pressed to generate a signal corresponding to a specific number, the dial circuit unit 4 detects this signal and generates a DTMF tone signal through the telephone line to call the telephone. You can do it.

However, such a conventional phone has a problem in that it cannot receive a call or make a direct call when it is necessary to leave the seat in an emergency call waiting situation.

Therefore, the present invention has been made to solve such a problem, the object of the present invention is to enter the phone number of the designated party's phone number and the location to which they are to move when waiting for an urgent call, the phone number It is to provide a service that automatically connects to a designated phone number when a call is received from the phone.

The present invention for achieving the above object is a telephone to which the Caller ID Service is applied to carry the information on the sender side between the ring signals to the receiver side,

Designating and storing a calling party's telephone number to be received and a call forwarding telephone number when absent; Detecting a ring signal; Generating a ring tone and starting counting; Processing, storing, displaying, and providing the transmitting side information to the microcomputer by the Caller ID IC; Determining whether an absent state is set; Determining whether the hook is on; Comparing the calling telephone number received from the microcomputer with the calling telephone number to be received when the ring tone is not set even when the ring tone is generated at least a predetermined number of times or the absence state is set; And outputting a call forwarding phone number if the received caller's telephone number and the caller's telephone number to be received coincide with each other.

The present invention configured as described above can be automatically connected to the call at another place even if you move to a seat during an emergency call waiting.

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

The Caller ID service applied to the present invention transmits data for the caller between the first tones and the second tones, which data is transmitted even if the caller does not agree to the service. However, the caller may have the option to prevent the transfer of data. In addition, the service transmits not only the name of the phone owner, but also various data such as the date, time and phone number the call came from.

The data is continuously transmitted at a speed of 1200bps using the FSK mode. Logic " 1 " is transmitted at 1200Hz and logic " 0 " is transmitted using a frequency signal at 2400Hz. The data consists of a 30-byte pulse signal, a mark signal, and a part for transmitting data.

FIG. 2 illustrates a multiple data message format (MDMF) method in which the caller's ID data is formatted in a transmission signal. The data signal starts to be transmitted 0.5 seconds after the first beep is sounded. It is composed.

First, the 30-byte pulse signal is composed of "0101 ..." and is transmitted for 250 ms, followed immediately by the mark portion for 70 ms, and then data is transmitted. Subsequently, depending on the call, a part having various temporal lengths is transmitted, which records the caller's name, month, date, hour, minute, and caller's telephone number.

Fig. 3 shows a Caller ID telephone capable of verifying the identity of a caller, which includes a keypad 10 for inputting a telephone number, a display unit 20 as an output display device, and a memory 30 for storing a designated telephone number. A microcomputer 40 for controlling the present system, a bell IC 50 for driving the bell 51, a DTMF generator 60 for generating a DTMF tone signal, and a telephone for shorting or connecting a telephone line It consists of a connection circuit 70, a Caller ID IC 80 for confirming the caller's telephone number, and a receiver 90.

4 is a flowchart illustrating an operation of a telephone to which a telephone is automatically connected through a telephone number pre-designation. The telephone number to be received and a call forwarding telephone number in the absence are designated through the keypad 10 and the memory 30 Storing a call signal, detecting a ring signal, generating a ring tone, starting a count when the ring signal is received, and transmitting the information on the transmitting side, which is carried between the ring signals, to the caller ID IC. Processing by 80 and storing in the memory 30, displaying the transmitting side information on the display unit and providing the information to the microcomputer 40, wherein the microcomputer 40 has received the caller's data in the step; Judging whether the provided telephone number is the same as a predetermined telephone number, and in the case of the same step, connecting to the telephone number to be connected and emitting a ring tone And comprising:.

One embodiment of the automatic telephone connection method through the telephone number dictionary designation that operates as described above will be described in more detail.

If the user waiting for an urgent call needs to move quickly, the user can enter the telephone number of the receiver and the telephone number of the sender, which are installed in the position to be moved, through the keypad 10 of the telephone. Put it in. Then, when the call comes in, the name and phone number of the calling party and the month, date, time, etc. are stored in the memory 30 from the Caller ID data received between the first ring signal and the second ring signal. 40). Thereafter, the microcomputer 40 determines whether a predetermined telephone number and the received Caller ID data match. When a call is received to an unspecified telephone number, the microcomputer 40 drives the bell IC 50 to ring the bell ( 51 is ringing and the telephone connection circuit 70 is connected to lift the handset 90 so that a call can be made.

On the other hand, when a call signal of the designated telephone number is input, the microcomputer 40 does not block and drive the bell IC 50, but controls the DTMF generator 60 to generate a DTMF signal of the telephone number to be connected to the telephone. You will be able to make a call because it will automatically connect.

As described above, the present invention designates the calling party's telephone number and the calling party's telephone number in advance, so that the telephone can be automatically connected to another place even when a seat is used in an emergency call waiting.
