Description

Method and apparatus for display a sender information, and for dialing automatically a communication company number}

The present invention relates to a caller information display and carrier number automatic dialing device.

In general, according to the development of electronic and communication technologies, telephones having various functions and technologies for providing various communication services to such telephones are being rapidly developed. Such telephones function as useful basic functions that are the basis of the information society, but due to their anonymity, they can also play a role in misuse such as prank calls and criminal activities.

Hereinafter, the transmission telephone number automatic receiving telephone according to the prior art (Utility Model Registration Application No. 20-1998-0006538) will be described.

1 is a block diagram of a transmission telephone number automatic receiving telephone according to an embodiment of the prior art. Referring to the configuration, a telephone unit 10 having a handset and various function buttons, and an entire system of the telephone are shown. The central processing unit 11 for controlling, the ring signal detection unit 12 for detecting a trunk line ring signal received by the telephone line 10 through a trunk line from outside, and connecting or disconnecting the trunk line with the telephone line 10. Trunk line control unit 13 for controlling the signal; speech network 14 for transmitting and receiving voice signals and various signals through trunk lines; and signal control unit 15 for controlling various voice signals between speech network 14 and telephone unit 10. It consists of

In addition, the guide voice unit 16 for transmitting the pre-stored guide voice to the trunk line through the signal controller 15 and the DTMF signal received through the trunk line, and also the DTMF signal according to the control signal of the central processing unit 11 DTMF signal detection and generation unit 17 for generating a signal, memory 18 for storing the telephone number of the transmission side corresponding to the DTMF signal detected by the DTMF signal detection and generation unit 17, and memory 18 And a display unit 19 for displaying the stored transmitting telephone number.

The operation of the transmission telephone number automatic reception telephone according to the prior art having such a configuration will be described.

First, when a user operates a predetermined number of keys of the number buttons provided in the telephone unit 10 to switch to the transmission telephone number reception mode, the central processing unit 11 receives the ring signal detection unit 12 from the trunk line ring signal. Check if it is input through.

At this time, when the CO line ring signal is input, the ring signal is immediately provided to the telephone unit 10 so as not to generate a ringing tone, and a call path is formed internally through the CO line control unit 13. The controller transmits a pre-stored telephone number input request message (for example, "I will connect you when you enter your telephone number") to the caller through the signal controller 15, the speech network 14, and the trunk line controller 13. After that, it waits for input of the caller's phone number.

Then, when the DTMF signal for the telephone number is received from the caller, the DTMF signal detection and generation unit 17 compares the DTMF signal for the calling party's telephone number with a previously stored data table to center the calling party's telephone number corresponding to the tone. It is provided to the processing apparatus 11.

The central processing unit 11 stores the caller-side telephone number information input from the DTMF signal detection and generation unit 17 in the memory 18 and displays it on the display unit 19 so that the user can easily check the same. The telephone unit 10 is controlled to generate a trunk line ringing tone. Then, after confirming the caller's telephone number displayed on the display unit 19, the user decides whether to talk. At this time, if the user does not determine the call for a predetermined time, that is, do not hook off the handset of the telephone within a certain time, the central processing unit 11 controls the trunk line control unit 13 to block the call path with the caller side. Let's do it.

On the other hand, when the user operates the search and select button attached to the key matrix (not shown) of the telephone, the central processing unit 11 stores a plurality of caller numbers stored in the memory 18 according to the number of times the search and select button is operated. Are sequentially read and displayed on the display unit 19. At this time, when the caller's telephone number desired by the user is displayed on the display unit 19, when the call button is selected from the key matrix of the telephone, the DTMF detecting and generating unit 17 controls the control of the central processing unit 11. The DTMF signal for the selected caller's telephone number is generated and transmitted to the calling party's telephone through the signal control unit 15, the speech network 14, the trunk line control unit 13, and the trunk line sequentially, thereby making a telephone call with the caller desired by the user. It is possible. Here, the telephone call between the sender and the receiver is made through an exchange (not shown).

However, in the prior art, since the caller must input the telephone number directly so that the user can confirm the information (the caller's telephone number), it is somewhat inadequate to fundamentally prevent prank calls or criminal acts.

At this time, when a signal including the voice signal and the telephone number of the transmitting side is input from the service side (exchange station) to the speech network 24, the voice signal detection unit 25 filters the received signal to detect the voice signal, and this voice The signal is transmitted to the telephone unit 20 by the control signal of the central processing unit 21 through the signal control unit 26 to enable a call between the transmitting side and the receiving side.

At the same time, the transmission information detection unit 26 filters the reception signal of the speech network 24 to detect the transmission telephone number signal, and inputs the transmission telephone number signal to the central processing unit 21.

The central processing unit 21 compares the incoming calling party number signal with the data table, decodes the calling party number, stores it in the memory 28, and simultaneously displays the corresponding calling party number on the display unit 29. do. At this time, since the caller tracking device (not shown) installed at the exchange station takes a predetermined time to track the caller, the caller's telephone number signal is added to the received signal of the speech network 24 for a predetermined time after the call path is formed. Not included. Therefore, the display unit 29 displays a message (for example, tracking) indicating that the source is being tracked under the control of the central processing unit 21.

If it is recognized as a prank call or intimidation call due to the contents of the call, the display unit 29 is checked to properly delay the end of the call until the caller's telephone number is displayed.

Subsequently, when the transmission information detection unit 26 detects the transmission telephone number signal from the reception signal of the speech network 24 and the transmission telephone number is displayed on the display unit 29 under the control of the central processing unit 21, the user is displayed. It is okay to hang up.

The operation of the caller information display and the operator number automatic dialing device according to the present invention having the above configuration will be described separately. First, the caller information display operation will be described.

When a caller makes a call and a DTMF signal corresponding to the telephone number is received by the switch 100, a caller tracking device (not shown) in the switch 100 tracks the caller information using the signal. Here, the caller information is the caller's telephone number and may also be the caller's telephone number and the caller's name information.

When the caller information is tracked by the caller tracking device in the switch 100, the caller information is loaded between the ring signal and the ring signal and transmitted to the telephone number input by the caller. At this time, the traced caller information is loaded between the first ring signal and the second ring signal and simultaneously transmitted to the caller information detection and DTMF signal generator 210 and the switching circuit 250. In addition, by using the time term between the ring signal and the ring signal (caller data (caller phone number data, caller name and address data)) by the FSK (Frequency Shift Keing) method to display the caller information and carrier number automatic dialing device ( 200).

The switching circuit 250 switches so that the trunk line is connected to the exchange 100 and the telephone 300 in the other cases except when the user makes a phone call using the telephone 300. That is, in the switching circuit unit 250, a control signal is received from the controller 220 according to the ring signal detection, and when the hook-off signal is detected from the telephone 300, the switch is switched to the switch 100, and conversely, the controller ( If the control signal according to the ring signal detection is not applied from the 220 and the hook-off signal is detected from the telephone 300, the switch is switched to the DTMF decoding unit 260.

In other words, when the ring signal is not detected and the hook switch of the telephone is turned off, the user is making a call. Therefore, the switch of the switching circuit unit 250 is switched to the DTMF decoding unit 260, and conversely, the ring signal is detected. When the hook switch of the phone 300 is turned off, the user picks up the handset to receive an incoming call. Therefore, the switch of the switching circuit unit 2250 switches to the switch 100 so that a voice call is made between the caller and the receiver. It is done directly.

Therefore, the ring signal including the caller information signal and the data transmitted from the switch 100 is transmitted to the telephone through the switching circuit 250 and at the same time the DTMF caller information signal or the caller data of the FSK method detects the caller information and generates the DTMF signal. It is detected through the unit 21. That is, the caller information is detected by demodulating the caller's telephone number signal (DTMF type telephone number signal) or caller's telephone number / name data (FSK data) transmitted from the exchange 100, and then detecting the caller information. Transmission to the control unit 220. That is, when the exchanger 100 transmits caller information using the DTMF scheme, only the caller telephone number signal may be transmitted, and when the caller information is transmitted through the FSK scheme, the caller telephone number and the caller name information may be simultaneously transmitted.

The controller 220 stores the caller information provided from the caller information detection and DTMF signal generator 210 in the storage 230 and simultaneously displays the caller information on the display 240 so that the user can easily check the caller information. After all, the caller information, that is, the caller's telephone number or the caller's telephone number and the caller's name information is displayed on the display unit 240 after one ring, and the user first checks the displayed caller's telephone number or the caller's telephone number and the name information. After that, you can answer the phone selectively.

After the user checks the caller information displayed on the display unit 240, when the hook switch of the phone 300 is turned off, the voice signal between the caller and the receiver is switched through the switching circuit unit 250 or the phone 300. Is sent directly to) to make a voice call.

Next, a description will be given of the automatic operator number dialing operation to reduce the call charge during the long distance / international telephone calls of the user.

First, when a user picks up the handset of the telephone 300 to make a call, that is, when the user hooks up the handset, the switching circuit unit 250 detects this, the handset is hawked off and the control unit 220 detects the ring signal. When no control signal is applied, the switch is switched to the DTMF decoding unit 260.

When the user presses the outgoing telephone number while the receiver is hooked off, the DTMF signal generator mounted inside the telephone 300 generates a DTMF signal for the telephone number pressed by the user and decodes the DTMF through the switching circuit 250. Transfer to section 260.

The DTMF decoding unit 260 decodes the DTMF signal for the received outgoing telephone number and provides it to the control unit 220.

The control unit 220 stores the outgoing phone number data provided by the DTMF decoding unit 260 in a predetermined area of the storage unit 230 and simultaneously determines whether the outgoing phone number is a local phone number, a long distance phone number or an international phone number. Determine.

As a result of the determination, if the outgoing telephone number input by the user is determined to be a local telephone number, the corresponding number is provided to the caller information detection and DTMF signal generator 210, and the outgoing telephone number input by the user is a long distance telephone number or international number. In the case of a phone number, the data is stored in the storage unit 230 and reads data on a communication provider number for reducing call charges during long distance and international calls, and the caller information detection and DTMF signal generation unit 210 together with the phone number input by the user. To pass). Here, the intercity / international business telephone number previously stored in the storage unit 230 may be set at the time of production of the product, or may be stored by arbitrarily setting the desired business number.

Accordingly, the DTMF signal generator 210 selectively generates DTMF signals corresponding to the local telephone number data or the telecommunication service provider number and the long distance / international telephone number data provided by the controller 220 and transmits them to the switch 100 through the trunk line. It is.

In this case, let's look briefly at the telephone number determination operation of the control unit 220.

It is determined whether the first number of the outgoing telephone numbers transmitted from the DTMF decoding unit 260 is "0". If the first number is "0", it is determined whether the second number is "1" or "8". .

As a result, if the second number is not "1" or "8", it is determined to be a long distance telephone number. If the second number is "1" or "8", the mobile number or "082" or "080" is determined. It is determined to be a free service telephone number.

On the other hand, if the first number is not "0", it is determined whether the total number of digits is 9 or more digits. If the total number is 9 or more, it is determined as an international telephone number. It is.

As described above, when the DTMF signal for the communication operator's telephone number and the caller's telephone number input by the user is transmitted to the switch 100, the control unit 210 provides a switching control signal to the switching circuit unit 250 to switch the switching. Switch to the Accordingly, the voice signal transmitted from the telephone 300 is transmitted to the switch 100 directly through the switching circuit 250, and the voice signal transmitted from the switch 100 is directly transmitted to the telephone 100 through the switching circuit 250. To be sent.

After the telephone call is completed between the caller and the receiver as described above, the user searches for the caller's phone number stored in the storage unit 230 and the user's recently called phone number. The number search and selection key 272 of the key input unit 270 is used. When a key input signal is provided by using the controller 220, the controller 220 sequentially reads the latest outgoing telephone number or the received outgoing telephone number stored in the storage 230 and displays the same on the display 240.

In this state, after selecting one phone number to be dialed among a plurality of phone numbers sequentially displayed by using the up / down navigation keys 273 and 374, and selecting the auto dial key 271, the controller 220 After determining the telephone number in the same manner as the above-described local / long / international telephone number determination operation, and transmits the communication operator number stored in the storage unit 230 and the corresponding telephone number selected by the user to the DTMF signal generator 210 It is.

Therefore, the DTMF signal generator 210 generates a DTMF signal corresponding to the telephone number provided by the controller 220 and transmits the DTMF signal to the switch 100 through the trunk line, thereby automatically storing the stored phone number and the operator number. will be.

With reference to the accompanying drawings, each of the caller information display and service provider automatic dialing method according to the present invention corresponding to the operation of the caller information display and operator number automatic dialing apparatus according to the present invention will be described step by step.

6 is a flowchart illustrating an operation of a method of displaying caller information according to the present invention.

First, when the caller information, that is, the caller's telephone number or the caller's telephone number and the caller's name information is transmitted from the switch 100 to the corresponding telephone (S101), the caller ID and the operator's number automatic dialing device 200 transmits from the switch 100. It is determined whether the ring signal including the caller information is received (S102). Here, the caller information is transmitted between the first and second ring signals by DTMF or FSK.

As a result, when caller information is received, the caller information is DTMF or FSK demodulated (S103).

The demodulated sender information is stored and displayed for the user to check at the same time (S104). At this time, the caller information provided from the exchange 100 is carried between the first ring signal and the second ring signal or transmitted using the time term between the first ring signal and the second ring signal in the FSK method within the term time. The phone's telephone number is displayed after the phone rings once. Therefore, the user can first check the caller information, and then selectively receive the call.

When a plurality of caller phone numbers are stored through the above process, the user determines whether there is a phone number search key input to delete unnecessary caller information among the stored caller phone numbers (S105). In step S106, a plurality of stored caller information is sequentially displayed according to a user's key input signal.

After selecting one caller information to be deleted from among a plurality of caller information sequentially displayed (S107), when a delete key signal is input, the corresponding caller information selected is deleted (S108).

FIG. 7 is a flowchart illustrating an operation of a service provider automatic dialing method according to the present invention. Referring to FIG.

First, the communication provider number for reducing the call charge during intercity and international phone calls are respectively set (S201).

Subsequently, it is determined whether a ring signal transmitted from the exchange is detected (S202). If a ring signal is detected, the caller's telephone number is displayed by the method shown in FIG. 6, and if the ring signal is not detected, the telephone receiver is hooked off. The application is detected (S203).

As a result of the detection, when the hook-off signal is detected, after switching the trunk line of the telephone to the operator number automatic dialing device, it is determined whether a DTMF signal corresponding to the outgoing telephone number input by the user is received from the telephone (S205).

As a result of the determination, when a DTMF signal corresponding to the outgoing telephone number input by the user is received from the telephone, the trunk line is switched to the exchange side, and then the received DTMF signal is decoded (S206).

It is determined whether the first number of the decoded outgoing telephone number is "0" (S207). When the first number is "0", it is determined whether the second number is "1" or "8".

On the other hand, if the first number is not "0" in step S207 it is determined whether the total number of the telephone number is 9 or more (S209).

When the second number is "1" or "8" in step S208, that is, when the first number is "0" and the second number is "1" or "8", a DTMF signal of the corresponding outgoing telephone number is generated. (S210), in step S208, if the second number is not "1" or "8", the inputted outgoing telephone number is determined as a long distance telephone number, and the preset long distance communication service provider number and the corresponding outgoing telephone number. A corresponding DTMF signal is generated (S211). Here, when the first digit number is "0" and the second digit number is "1" or "8", the mobile phone (011, 016, 016, 017, 018) or the pager number (012, 015) or the toll free number It is the same number as the phone number "080".

On the other hand, if the total digits of the outgoing call number entered by the user in step S209 is 9 or more digits, it is determined that the input outgoing phone number is an international phone number and corresponds to a preset international telephony service provider number and the corresponding outgoing call number. Generating a DTMF signal (S212), and if the total digits of the outgoing phone number input by the user in step S209 is 9 digits or less, it is determined that the outgoing phone number input corresponds to the outgoing phone number; The DTMF signal is generated (S213).

Subsequently, each DTMF signal generated in steps S210 to S213 is selectively transmitted to the exchange (S214).

Briefly summarizing the above method of automatic dialing of a provider number, when a user enters a telephone number to make a call, the first number of the entered telephone number is "0", and the second number is "1" or "8." "," And if the first number is not "0" and the total number of digits entered is 9 digits or less (7 ≤ total number of digits ≤ 8), the call is judged not to be a long distance or international number. Only the DTMF signal corresponding to the telephone is generated and transmitted to the exchange.

On the other hand, if the first number of the telephone number input from the user is "0" and the second number is not "1" or "8", it is determined that the input telephone number is a long distance telephone number, and the first number If is not "0" and the total number of entered telephone numbers is 9 or more, it is determined that it is an international telephone number and the DTMF signal corresponding to the corresponding outgoing telephone number together with the preset service number for long distance or international telephone call reduction. The operator number DTMF + outgoing telephone number DTMF) is generated and transmitted to the exchange.

With reference to the accompanying FIG. 8, a method of automatically calling and searching a stored caller's phone number and a user's recently called phone number in the caller display method and the operator's automatic dialing method will be briefly described.

8 is a flowchart illustrating an operation of a method for automatically dialing pre-stored caller information and a recent telephone number sent by a user.

First, it is determined whether a recent outgoing telephone number search key signal has been input (S301).

As a result of the determination, when a recent outgoing telephone number search key signal is input, the first displayed telephone number is sequentially displayed according to the user's key input signal (S302).

If the recent outgoing call number search key signal is not input in step S301, it is determined whether the caller call number search key signal is input (S303).

As a result of the determination, the prestored caller numbers are sequentially displayed according to the user's key input signal (S304).

Subsequently, one of the latest outgoing telephone numbers or the received outgoing telephone number displayed sequentially is selected to make a call (S305), and it is determined whether the selected corresponding number is a city, a long distance or an international phone number (S306). Here, since the method of determining whether the selected telephone number is a local telephone number, a long distance telephone number or an international telephone number has been described above, the detailed description thereof will be omitted.

When the telephone number selected by the user in step S306 is a local telephone number (S307), a DTMF signal corresponding to the telephone number is generated and transmitted to the exchange (S309). When the telephone number selected by the user is a long distance telephone number, In operation S310, a DTMF signal corresponding to the preset long distance telecommunications operator number and the corresponding telephone number selected by the user is generated and transmitted to the exchange (S310).

On the other hand, if the telephone number selected by the user is an international telephone number, a DTMF signal corresponding to the preset international telephone communication service provider number and the corresponding telephone number selected by the user is generated and transmitted to the exchange (S311).

Hereinafter, when a user enters a long distance / international telephone service provider number to make a call, the service provider's automatic dialing method will be described in detail with reference to the accompanying drawings.

9A and 9B are flowcharts illustrating an operation of another embodiment of a service provider automatic dialing method according to the present invention.

Since operations from steps S401 to S407 shown in FIG. 9 are the same as those of FIG. 7, description thereof will be omitted.

First, if the number of the first digit of the outgoing telephone number decoded in step S407 is not "0", it is determined whether the total number of digits of the corresponding outgoing telephone number is 9 characters or more (S409).

As a result, when the total number of digits is 9 or more, it is determined that the corresponding outgoing telephone number is an international telephone number, and generates a DTMF signal for the preset international operator number and the outgoing telephone number input by the user and transmits it to the exchange 100 ( S410).

On the contrary, if the total number of digits of the outgoing telephone number input by the user is 9 digits or less, the outgoing telephone number is determined as the local telephone number, and the DTMF signal corresponding to the corresponding number is generated and transmitted to the exchange 100 through the trunk line. (S411).

On the other hand, if the first digit number of the outgoing telephone number decoded in step S407 is "0", it is determined whether the second digit number of the outgoing telephone number input by the user is "0" or "1" or "8". It is determined (S408).

If it is determined that the second digit is not "0" or "1" or "8", the outgoing telephone number is regarded as a long distance telephone number and the DTMF signal for the preset long distance telephone number operator number and the outgoing telephone number is determined. It generates and transmits to the exchange 100 (S413).

However, when the second digit is "0" or "1" or "8" in step S408, it is determined whether the number of the second digit is "1" (S412), and the number of the second digit is "1". In the case, the caller ID is determined as a pager or a mobile phone number, and a DTMF signal corresponding to the number is generated and transmitted to the switch 100 (S414).

If the second digit number is not '1' in step S412, it is determined whether the second digit number is "0" (S415), and if the second digit number is not "0", the third digit is determined. It is determined whether the number is "0" (S417).

As a result, when the third digit number is "0", the outgoing telephone number is determined as a toll-free service telephone number, that is, a phone number such as "080", and a DTMF signal corresponding to the outgoing telephone number is generated to generate an exchange ( 100) (S418), and if the third digit number is not "0", the number is a suburban telephone number, i.e., a suburban carrier number including "081", "082", and "083". After judging by the phone number and deleting the first digit from the third digit (S419), a DTMF signal is generated for the preset long distance telephone operator number and the calling number corresponding to the deleted telephone number. The transfer to the exchange 100 (S420).

On the other hand, if the second digit number is "0" in the outgoing telephone number input by the user in step S415 it is determined whether the third digit number is "1" or "2" or "8" (S416).

If the third digit is not "1" or "2" or "8", the international telephone number with the international telephone number (00727, 00300, 00365, 00700, 00344, 00755, 00766) is determined. After determining that the first to fifth digits are deleted from the input telephone number, the DTMF signal is generated for the preset international telephone operator number and the remaining telephone numbers from which the five digits are deleted. (S421).

However, if the third digit is "1" or "2" or "8", the first telephone number entered is determined to be an international telephone number including the international telephone operator number (001, 002, 008). After deleting the digits from the digit to the third digit (S422), a DTMF signal for the preset international telephone operator number and the remaining telephone number from which the three digit number is deleted is generated and transmitted to the switch 100 (S423). ).

After all, if the outgoing telephone number entered by the user to make a call includes a long distance / international telecommunications carrier number, the included long distance / international carrier number is deleted, and then the preset long distance / international carrier number and the deleted number. DTMF signal for the remaining outgoing telephone number other than the number is automatically generated and transmitted to the exchange 100.

If the outgoing phone number including the long distance / international business number is stored in the storage unit 230, the one selected by the user among the stored outgoing phone numbers is the phone number including the long distance and international business phone numbers. After deleting the service provider number, the preset service provider number is automatically dialed.

In the above, the present invention has been described only with respect to an example in which the present invention is separately configured to be detachable from the telephone, but such a device may be mounted inside the telephone, as well as a corded telephone, a wireless telephone (PCS, DCS, City Phone), a modem. It can be understood by anyone of ordinary skill in the art that the same method can be applied to a PC capable of communication.

As described above, the caller information display and the operator number automatic dialing device and the method thereof constitute a separate device having a caller phone number information display function so as to be detachable from a general telephone and perform the corresponding function. Since there is no need to purchase a separate phone in order to reduce the cost of purchasing a phone with a corresponding function.

In addition, by automatically dialing a predetermined corresponding carrier number for the reduction of call charges for long distance and international calls of the caller, there is another advantage that can reduce the call charges for long distance and international calls.

In addition, since the caller's telephone number is displayed immediately after the phone rings, the user can check the caller's telephone number before the call is received. Therefore, there is an advantage in that the caller can selectively receive the call according to the caller's telephone number.
