Abstract

PURPOSE:To surely recognize a caller telephone number in an incoming call side by adopting the constitution of manual input by an instruction from a called party if an originating telephone set has no automatic sending function of a calling telephone number. CONSTITUTION:An originating telephone number stored in advance in a memory 22 is sent to a line 32 together with a called party telephone number and demodulated by a modulator/demodulator 36 at the called party 12. The demodulated called telephone number is stored in a memory 55 and becomes the originating telephone number when the called party 12 makes in turn a call. Moreover, the democulated calling telephone number is stored once in a memory 40 and displayed on a display device 42. If said number automatic sending function is not available for the originater 10, a signal reception detecting section 44 of the called party 12 detects the absence of the signal of the caller/called party number to be sent from the originater 10, operates a holding part 46 to bring a line 32 in the hooked-off hold state. Then a instructing device 48 gives the instruction of manual input of the originating telephone number to the caller.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a telephone number recognition device that is attached to a general subscriber telephone set of a called party and displays the telephone number of a calling party.

(Prior Art) Conventionally, as a method for recognizing the calling party's telephone number on the receiving side, there is a reverse detection method in which the telephone number is sequentially searched manually at the switching office of the subscriber telephone line.

Also, as a method of recognizing the calling party's telephone number,
There is a technique disclosed in Japanese Patent No. -59851. This uses telephones combined with a telephone number recognition device on the calling and called parties, and when the calling party calls the called party, the calling party's telephone number, which has been stored in advance on the calling party, is transferred to the called party. This is a method of transmitting a telephone number followed by a message and displaying it on the called party.

(Problems to be Solved by the Invention) However, the above conventional method has the following problems.

The conventional method of knowing the calling party's telephone number by performing reverse detection is a method of recognizing the calling party's telephone number on the exchange side, and is only used in special cases when using general subscriber telephone lines. This method is not common and requires a certain amount of time to recognize the calling party's telephone number, so it cannot be used to instantly recognize the calling party's telephone number on the called party. Therefore, even if you receive a call, you cannot confirm the identity of the other party until you pick up the receiver and begin the call, and even after the call has started, you cannot confirm the identity of the other party unless the other party identifies himself or herself. The drawback is that you cannot select the person to answer the call. For this reason, these characteristics of telephones were often exploited and used as a means of intimidation and harassment. In addition, if you receive a call while you are away, unless you use an answering machine to automatically answer and record the call, you will not be able to tell who the caller is or even that the call was received. There is the inconvenience of not having one.

Although the technique disclosed in Japanese Patent Application Laid-Open No. 60-59851 can solve the above-mentioned inconvenience, it has the following problems.

Since the calling party identification information is sent and received without charge, it becomes possible to send and receive information other than the calling party identification information for free, and there is a risk that it will be misused.

Another problem is that it does not function unless devices are attached to both the originating and destination terminals.

Furthermore, in order to send and receive caller identification information without charge, it is necessary to use the trunk of the switching center, and the network needs to be modified to some extent, which is not possible just by changing the subscriber terminal. Yes.

Therefore, in the present invention, there is a charge for transmitting the calling party identification information, and if the called party has a telephone number recognition device, it is not necessarily necessary for the calling party to transmit the calling party identification information by simply incorporating it into the terminal telephone. It is an object of the present invention to provide a telephone number recognition device capable of performing various information processing including.

(Means for solving problems) In order to solve the above problems, the present invention has the following configuration.

That is, a modem that modulates and demodulates signals to be sent and received, a transmission/reception switch connected to the modem to switch between sending and receiving signals, a call start detection section to check hook-off on the called side, and a telephone on the calling side. a signal detection unit that detects the signal generated from the signal detector, a code conversion unit that converts the signal detected by the signal detection unit into a predetermined code as necessary, and a code conversion unit that converts the signal detected by the signal detection unit or coded code. a P/S converter for serially converting the signal and sending it out on the line; a signal reception detection unit for detecting the presence or absence of a signal indicating the called party's and calling party's telephone numbers upon reception; and a receiving party that has received the signal. and an S/P converter for parallel converting a signal indicating the calling party's telephone number, etc., a display device for displaying the received calling party's telephone number, etc., and when there is no signal indicating the calling party's telephone number in the received signal. a hold part that puts the line in a hold state for non-paid calls, an indicator that instructs the calling party to input the calling party's phone number when the hold part is activated and the line is held, and a hold part that automatically or It is characterized by comprising a hold switch that can be manually switched and a memory for storing received telephone numbers of the called party and the calling party.

(effect) The operation will be explained with reference to FIG.

First, when the calling side 10 inputs the telephone number of the called side 12 into the telephone 14 of the calling side 10, the signal detection section 18 detects the input signal, and the code conversion section 20 converts the signal into a hexadecimal code. . The 16 evolved code is temporarily stored in memory 22.
When the call start detection section detects that the called party 12 has hooked off, the stored code is serially converted by the P/S conversion section 24, modulated by the modem 28, and sent out onto the line 32. . Subsequently, the pre-stored calling party telephone number is also transferred to the memory 22, the P/S converter 24, and the modem 2.
It is also sent out on the line 32 via 8, and enters the destination 12 via the exchange 34. At the receiving side 12, signals indicating the called side telephone number and the calling side telephone number, which are the numbers of the own station, are sent to the modem 3.
6, the telephone number code of the calling party 10 is detected by the signal reception detection section 44, and the demodulated signal is sent to the S/P conversion section 38.
The phone number of the calling party 10 is stored in memory 40.
The information is temporarily stored and displayed on the display 42.

Further, the called party's telephone number, which is the telephone number of the own station, is stored and held in the memory 55.

If the calling side 10 does not have a telephone number recognition device, the signal reception detection unit 44 sends a signal to activate the hold unit 46, and the hold unit 46 holds the line 32 in a hook-off state and also instructs the calling side 10. 48 to input the calling party's telephone number.

When the calling party 10 inputs the calling party's telephone number, the signal on the line 32 enters the code converting part 54 from the signal detecting part 52 via the holding part 46 and is converted into hexadecimal code, and the hexadecimal code is temporarily stored in the memory 56. and displayed on the display 42.

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As an additional function, it has an expansion system 60 connected to the interface 58 such as an external memory, a recording device, and other peripheral devices.

Next, the operation will be explained.

First, with reference to FIG. 1, a case will be explained in which the present device is installed at both terminals on the originating side 10 and the receiving side 12.

First, when the calling side 10 inputs the telephone number of the called side 12 from the telephone 14, it calls the telephone 51 of the called side 12, and the signal detection section 18 detects a DTMF signal or a pulse signal and sends it to the code conversion section 20. .

The code conversion section 20 converts the DTMF signal or pulse signal into a hexadecimal code. In this case, the signal may be directly used as a decimal code from O to 9 without hexadecimal conversion, but until this device becomes widespread, it is not possible to receive signals from telephones that do not have this device installed. Since the number cannot be detected, it is necessary to evolve to 16 for the time being.

16 The evolved telephone number code of the called party 12 is stored in the memory 22.
Once the call start detecting unit 30 confirms the start of the call, the transmitting/receiving switch 26 changes to the transmitting state, while the called party's telephone number and
The calling party phone number stored in the P/S converter 24
and is serially converted. The signal is then modulated by the modem 28, sent out on the line 32, and delivered to the receiving side 12 via the exchange 34 installed in the switching center.

Note that the method for confirming the start of a call in the call start detecting section 30 is by measuring the line level, but a commonly used loop detection circuit may also be used.

The calling party's telephone number, which is stored in advance in the memory 22 of this embodiment, is the called party's telephone number when a call is received from another terminal having this device to the calling party 10 after this device is installed at the calling party gj 10, that is, the calling party's telephone number. Since the telephone number of the calling party 10 is memorized, there is absolutely no possibility of making a mistake in the calling party's telephone number. Therefore, RAM is used as the memory. Of course, it is possible to use ROM, but RAM is preferable in consideration of relocation and the like.

times! The signal indicating the telephone numbers of the destination and originating parties sent to the terminal 32 enters the destination 128, is demodulated by the modem 36, and the demodulated signal is converted from serial to parallel by the S/P converter 38. The side telephone number is stored in the memory 55 and becomes the calling side telephone number when the called side 12 becomes the calling side.

Further, the parallel-converted calling party telephone number is temporarily stored in the memory 40, and the calling party telephone number is displayed on the display 42.

Next, we will discuss the operation when the calling party does not have this device.

When a call signal arrives at the destination side 12 and the hook-off occurs, the signal reception detection unit 44 of the destination side 12 detects that there are no signals of the phone number of the destination side and the origination side that should be sent from the calling side, and the hold unit 46 is activated. Then, the line 32 is in a hooked-off hold state, and the voice oscillator of the instruction section 48 instructs the calling party to manually input the calling party's telephone number. A signal corresponding to the calling party's telephone number is detected by the signal detecting section 52 , converted into a hexadecimal code by the code converting section 54 , and then input to the memory 56 and displayed on the display 42 . After the display is confirmed, the hold unit 46 releases the hold.

The hold section 46 can be activated manually by the hold switch 50 even when the calling party has this device, that is, if you want to confirm the calling party's telephone number before starting a call, so it should always be turned on. If this is done, the telephone number of the line can be recognized by the called party 12 before the call starts.

The above is the operation of this device, but since this device temporarily stores the calling party's telephone number in the memory 40 or 56 of the destination party 12, the destination party 12 can be provided with various additional functions. Become. An example of its application will be explained next.

First, we will discuss how to use this device as an answering machine.

If the hold switch 50 is manually turned on at the called party 12, the calling party's telephone number is always temporarily stored in the memory 56, so it can be saved as data in an external memory or recording device via the interface 58, and it can be saved after returning home. By pulling out the data, you can find out the phone number of the caller who called you while you were away.

Next, the calling party telephone number selection system will be described.

The primary purpose of this device is to know the calling party's phone number.
The obtained calling party telephone number is processed as data.

That is, by manually turning on the hold switch 48 of the hold section 46 of the called party 2, the line state can be held in the hook-off state before hooking off, and the telephone number of the calling party can be known. 5
If a system is set up in which only a pre-registered caller's telephone number is connected via 8, only specific telephones will be connected, making it possible to use the telephone for emergencies or as a hotline. It can also eliminate unnecessary calls and prank calls.

Next, we will discuss an information processing system combined with a computer system.

Information corresponding to the calling party's telephone number is registered in a computer system, and the receiving party 12 uses the incoming calling party's telephone number as an identification code and retrieves it from the computer system.

For example, in a medical institution, the content of a patient's medical record is made to correspond with the patient's medical record, and the contents of the medical record are instantly displayed on a display. This can greatly reduce the amount of time it takes to search for medical records.

Similarly, for the police and fire departments, it is possible to match the caller's phone number with a map to know the location of an incident, or to match the company's customer information to quickly retrieve information. It becomes possible to react immediately.

Furthermore, a system that sends data corresponding to the calling party's telephone number for data communication is also possible, and a meter reading system that sends the amount of electricity, water, gas, etc. used to the calling company can be connected via an interface. It is possible.

Various information processing is possible through other interfaces, and there are infinite possibilities.

Although various preferred embodiments of the present invention have been described above,
The present invention is not limited to the embodiments described above; it goes without saying that many improvements can be made without departing from the spirit of the invention.

(Effects of the Invention) By using the telephone number t=86 device according to the present invention, it becomes possible for the called party to recognize the calling party's telephone number regardless of the presence or absence of the calling party's telephone number recognition device; Since there is a charge for this service, it is possible to prevent unpaid communications.

Furthermore, by using the hold changeover switch, it is possible to know the calling party's telephone number before making a call, allowing the receiving party to select whether or not to make a call, thereby preventing crimes by telephone.

Technically, there is no need to improve the general subscriber telephone line network at all; all that is required is a change at the end. It is also effective in all aspects, such as being able to be expanded and applied to a variety of uses by combining with other systems.
