How to speed dial your phone {MEMORY DIALING METHOD FOR TELEPHONE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speed dialing technology of a telephone, and in particular, to check the balance of a bank account, look up various services of a credit card, call a pager, or make an international call using an automatic answering function of a telephone. When it is necessary to press a button having a relatively large number of digits, such as when you want to use a shortcut key to speed dialing method of the phone to be able to dial more simply and conveniently.

In a conventional telephone, a speed dialing function can be used for a commonly used telephone number. However, an automatic answering function can be used to query the balance of a bank account, call a pager, or make an international call. If you need to press a button with a relatively large number of digits, such as when you want to hang, you could not use the shortcut function. Therefore, in this case, the user must press the corresponding buttons one by one.

For example, if you want to use the bank's automatic answering function (ARS) to check your bank account balance, enter "Answering phone number → Entering service code (e.g. deposit or inquiry) → Enter bank code number → Account Press the number and the special code (#, *) buttons corresponding to "Enter number → Enter password" in order.

As another example, if you want to look up the credit card, enter the answering machine phone number → enter the service number (for example, lost, payment, use amount, etc.) → enter the account number → enter the password "and the special code ( #, *) Button should be pressed sequentially.

As another example, when a pager is to be called, the buttons corresponding to the calling number must be sequentially pressed, and then the buttons corresponding to the telephone number (eg, their telephone number) to be contacted must be sequentially pressed.

As another example, if you want to make an international call (Internet phone, international call using a separate communication), after receiving a certain tone (e.g. A tone) by pressing the multi-digit phone number button for the primary connection, Then press the button corresponding to the rest of the phone number in sequence.

Thus, although a conventional telephone number is provided with a speed dialing function for a conventional telephone number, it is very cumbersome to dial a number of cumulatively, for example, a balance check of a bank account or an account transfer or credit card payment using an automatic answering function. There was a defect that speed dialing function was not provided for payment inquiry, dialing for pager, and dialing for international calls. Therefore, a large number of digits must be manually entered manually, and this is not only annoying to re-enter wrong numbers, but also causes an economical loss due to unexpected charges.

Therefore, an object of the present invention is to use the automatic answering function when you need to press a relatively large number of buttons, such as when checking the balance of the bank account, querying various services of the credit card, calling a pager or making an international call. Correspondingly, it stores the numbers necessary for speed dialing, detects the voice signal for automatic answering after dialing for connection, and automatically transmits the corresponding numbers at that time, and locks speed dialing using the master card as necessary. An object of the present invention is to provide a speed dialing method of a telephone, which enables a function.

Fig. 1 is a block diagram of a telephone to which a speed dialing method according to the present invention is applied, and as shown therein, a DTMF driver 6 is driven in accordance with a key signal input from a switch matrix 1 by a user so as to correspond to a telephone number. A central processing unit (2) configured to be dialed in and to perform a speed dialing function using the first memory section 3A and the second memory section 3B; A first memory unit 3A which stores a speed dial number for checking balance of a bank account or inquiring whether a bank transfer or a credit card is charged; A second memory unit 3B, which is composed of a plurality of detachable memory chips and stores respective telephone numbers for speed dialing; A display unit 4 for performing a normal display function and a handset 5 for handset; A DTMF driver 6 for generating a complex frequency tone DTMF corresponding to a telephone number under the control of the central processing unit 2; A call circuit unit 7 for transmitting the complex frequency type tone DTMF to the switchboard via trunk lines L1 and L2, and processing a voice signal to make a call with the other party; A power supply unit (8) for separating and detecting a predetermined power supply from the trunk lines (L1, L2) and supplying a voltage required by each system section; With reference to Figures 2 and 3 attached to the operation of the present invention configured as a signal detection unit 9 for detecting that the voice signal is input through the call circuit unit 7 as follows.

First, a process of storing and sending a speed dial number for retrieving the balance of a bank account using an ARS of a bank is described as follows.

The following describes an example of an automatic answering telephone number: 1588-1599, a service number: 111 #, an account number: 123-1234-123, and a password: 1234.

The storage mode is set by the user pressing the [input / end] button provided in the switch matrix 1, and the storage address is set by the user pressing a specific button provided in the switch matrix 1.

Thereafter, the user presses a button corresponding to the primary sending number, that is, the answering machine telephone number (bank access number) '1588-1599', in the switch matrix 1, and the central processing unit 2 inputs the input. The number is stored in the first memory unit 3A. After confirming that the user presses a specific button (aka T button), the first delay time T1 (for example, T1 ≒ 8 seconds) is set accordingly. Will be saved.

Subsequently, the user presses a button corresponding to the secondary transmission number, that is, the service number '111 #', in the switch matrix 1, and at this time, the CPU 2 inputs the input number to the first memory unit. 3A, and after confirming that the user presses a specific button, the second delay time T2 (for example, T2 ≒ 2 seconds) is set and stored accordingly.

Thereafter, the user presses a button corresponding to the third sending number, that is, the account number '123-1234-123', in the switch matrix 1, and the central processing unit 2 deletes the input number. 1 is stored in the memory unit 3A, and after confirming that the user presses a specific button, the third delay time T3 (for example, T3 ≒ 2 seconds) is set accordingly.

Thereafter, the user presses a button corresponding to the fourth order sending number, that is, the password '1234' in the switch matrix 1, and then presses the [input / end] button. In this case, the central processing unit 2 inputs the input. Is stored in the first memory section 3A and the storage mode is terminated.

On the other hand, when the user wants to send the number of the stored autoresponder through the above process by using the shortcut button, the user presses a specific button provided in the switch matrix 1.

At this time, the CPU 2 reads the answering machine telephone number '1588-1599' stored in the predetermined address of the first memory unit 3A after confirming the button input, and drives the DTMF driver 6. A DTMF signal corresponding to the answering machine telephone number '1588-1599' is generated. The DTMF signal generated in this way is transmitted to the exchange side via the call circuit unit 7 and the trunk lines L1 and L2.

At this time, the signal detection unit 9 detects the ring signal output from the exchange side and outputs the voice detection signal DET accordingly to the central processing unit 2, and the central processing unit 2 from the time point. After waiting until the delay time (T1 ≒ 8 seconds) elapses, the service number '111 #' is read from the first memory unit 3A, and the corresponding DTMF signal is transmitted to the counterpart as described above.

That is, the delay time (T1) is a different delay time in consideration of the time until the exchange outputs the ring signal to the other party, the connection with the other party through the trunk line (L1, L2) and then the automatic answering voice signal is received. It is a relatively longer time than T2 and T3).

Thereafter, when the signal detection unit 9 detects a voice signal "Please enter the account number" and outputs the voice detection signal DET to the CPU 2, the CPU 2 causes the delay. It waits for the time (T2 ≒ 2 seconds) to elapse and then reads the account number '123-1234-123' and outputs the corresponding DTMF signal.

Thereafter, when the signal detection unit 9 detects a voice signal "Please input a password" and outputs the voice detection signal DET to the CPU 2, the CPU 2 causes the delay. It waits for the time (T3 ≒ 2 seconds) to elapse, reads the password '1234', outputs the corresponding DTMF signal, and ends.

2A illustrates an embodiment of the signal detector 9. The voice signal input to the call circuit unit 7 through the trunk lines L1 and L2 is supplied to the non-inverting input terminal of the comparator CP and compared with the reference voltage V _ref supplied to the inverting input terminal. However, the reference voltage V _ref is set slightly lower than the voltage supplied to the non-inverting input terminal when the voice signal is input to the call circuit unit 7 as described above. Therefore, when the voice signal is detected, the voice detection signal DET is activated 'high' in the comparator CP.

2b shows another embodiment of the signal detector 9. When the telephone number for connection is dialed and a voice signal for automatic answering is output from the other party after the connection is made, the voice signal is smoothed in the capacitor C1 through the trunk lines L1 and L2 and the call circuit unit 7 so that the transistor ( The bias voltage of Q) is supplied. Accordingly, since the transistor Q is turned on, the voice detection signal DET output from the collector of the transistor Q is activated as 'low'.

In the above description, all of the speed dial number storing process is performed by the user, but in order to reduce user's hassle, a number that can be stored before the product is shipped, for example, an automatic answering phone number or a service number is stored in advance. You can save the rest of the numbers after shipping. In the above description, the respective delay times T1, T2, and T3 are 8 seconds, 2 seconds, and 2 seconds. However, the delay time T1, T2, and T3 may be changed by using a setting program according to the system environment.

In the above description, the numbers for speed dialing are stored in the first memory 3A as an example. However, the same effect can be obtained when the numbers are stored in the second memory 3B. The first memory 3A and the second memory 3B may be embodied in various forms, and may be embodied as in Korean Utility Model Registration Application No. 99-4250 filed by the present applicant.

In addition, it is possible to more easily perform bank account transfers (other banks, banks concerned), credit card inquiries (for example, loss, payment, use amount, etc.) using the above method.

Meanwhile, as another embodiment of the present invention, a speed dialing method using a specific button * (or #) may be mentioned. That is, when a single '*' (or '#') button signal is inserted in the memory area designated by the predetermined shortcut button, the phone number stored in the memory area designated by the shortcut button is transmitted first, and then ' The phone number in the * '(or' # ') field is sent secondarily. In addition, when two '*' or '#' button signals are inserted in the memory area designated as a predetermined shortcut button, the phone number in the '*' or '#' area is transmitted first, and then the phone number stored in the address To send the secondary.

First, an exemplary speed dialing method using a specific button '*' will be described as follows. Here, the pager number: 015-1234-1234, the telephone number of the user to be contacted: 02-549-6934 as an example.

The storage mode is set by the user pressing the [input / end] button provided in the switch matrix 1, and the storage address is set by the user pressing a predetermined button provided in the switch matrix 1. Thereafter, the user presses a specific button '*' in the switch matrix 1 and then presses a button corresponding to the call number '015-1234-1234' of the pager. At this time, the CPU 2 stores the input number in the second memory unit 3B. After confirming that the user presses a specific button, the CPU 2 sets and stores the delay time T accordingly. Then, the user presses the [input / end] button again.

If the phone number (02-549-6934) of the user to be contacted at the address designated by the specific button '*' has already been stored, the following storing process may be omitted, but otherwise, the following storing process should be performed according to the following procedure. do.

The storage mode is set by the user pressing the [input / end] button provided in the switch matrix 1. After that, the specific button '*' will be pressed. At this time, the pressing duration will be slightly longer. After that, the user presses a button corresponding to the telephone number '02 -549-6934 'to be contacted, and then presses the [input / end] button again.

On the other hand, when the user presses the predetermined button, the CPU 2 reads the call number '015-1234-1234' from the corresponding chip of the second memory unit 3B and transmits the corresponding DTMF signal through the above path. Will be sent. Thereafter, when the voice detection signal DET is input from the signal detection unit 9, the phone number '02 -549-6934 'to be contacted at the address designated by the specific button' * 'after a predetermined delay time from the input point of time. It reads and transmits the corresponding DTMF signal through the above path. As a result, the other party is called and the telephone number to be contacted is transferred to the corresponding pager.

In the above example, the use of a specific button '*' has been described. However, the same effect can be obtained when another specific button '#' is used.

In addition, an exemplary speed dialing method using the specific button '*' twice will be described as follows. Here, the bank account number: 123-12345-123, the bank service number: 111 #, the access telephone number: 1588-1599 will be described as an example.

The storage mode is set by the user pressing the [input / end] button provided in the switch matrix 1, and the storage address is set by the user pressing a predetermined button provided in the switch matrix 1. Thereafter, the user presses a specific button '*' twice in succession in the switch matrix 1 and then presses a button corresponding to the bank account number '123-12345-123'. At this time, the CPU 2 stores the input number in the second memory unit 3B. After confirming that the user presses a specific button, the CPU 2 sets and stores the delay time T1 accordingly. Then, press the button corresponding to the bank service number '111 #' and then press the [Enter / End] button again.

If the access telephone number '1588-1599' is already stored at the address designated by the specific button '*, *', the following storing process may be omitted. Otherwise, the following storing process should be performed.

The storage mode is set by the user pressing the [input / end] button. After that, the specific button '*' will be pressed. At this time, the pressing duration will be slightly longer. Thereafter, the user presses a button corresponding to the access telephone number '1588-1599', and at this time, the CPU 2 stores the input number, confirms that the user presses a specific button, and then delays accordingly. Set and save time T2. Then, the user presses the [input / end] button again.

On the other hand, when the user presses the predetermined button, the central processing unit 2 reads the connection telephone number '1588-1599' from the corresponding chip of the second memory unit 3B and transmits the corresponding DTMF signal through the above path. Will be sent.

Thereafter, when the voice detection signal DET is input from the signal detection unit 9, the bank account number '123-12345-123' is read after the predetermined delay time T2 from the input time point. The DTMF signal is sent out. Thereafter, when the voice detection signal DET is input again from the signal detection unit 9, the bank service number '111 #' is read out after the predetermined delay time T1 from the input time point.

In the above example, the use of the specific button '*' has been described, but the same effect can be obtained when another specific button '#' is used.

On the other hand, when speed dialing is used to inquire the balance of a bank account or to inquire various services of a credit card as described above, it is necessary to prevent abuse by a third party. An embodiment of the present invention for preventing this will be described below.

As described above, when storing a phone number or the like for speed dialing, a specific symbol (eg, M) is inserted and stored according to a user's request. Subsequently, when a corresponding telephone number is read out, a specific symbol (for example, M) is detected, and at this time, the central processing unit 2 corresponds to one of a plurality of memory chips detachably attached to the second memory unit 3B. The contents of the memory of the chip inserted into the area are scanned, and speed dialing is performed only when the manufacturing number and the password are the same as those stored in the main body.

On the other hand, as another embodiment of the present invention, it is possible to use a simple button operation of the user without setting the delay time as described above, or separately detecting the signal for the automatic response. That is, when a user directly listens to the voice signal for automatic response and presses a specific button (for example, '*' or '#'), the number of the corresponding sequence may be transmitted.

As another embodiment of the present invention, a large number of pieces of information stored in the first memory unit 3A and the second memory unit 3B, respectively, can be easily changed (copyed) with a single button operation for speed dialing. For example, the processing thereof is as follows.

The user presses the [Enter / End] button a predetermined number of times (eg, six times) to set the data copy mode, inputs a predetermined number of passwords (eg, '1234'), and then presses the [Enter / End] button again. . At this time, the CPU 2 checks whether the input password (for example, 1234) matches a preset and stored password and matches the first and second memory units 3A and 3B when they match. Change each data stored in the) to new data.

As another embodiment of the present invention, a storage process for speed dialing of an international telephone number is as follows. The speed dialing method using the speed dialing method is similar to the above example.

Press the [ENTER / END] button → enter access number → set delay time → enter password → enter ID number → set delay time → enter phone number → press [ENTER / END] button.

As described in detail above, the present invention can provide the convenience of use by enabling the user to inquire the balance of the bank account, query the various services of the credit card, call a pager or make an international call by using the automatic answering function. It has an effect. In addition, there is no effect of wrongly pressing a large number of telephone numbers, ultimately reducing access time and unnecessary disadvantages such as unnecessary charges can be prevented.
