Description

AUTOMATIC DIALING APPARATUS AND METHOD THERE OF}

The present invention relates to an automatic dialing device and a method, comprising: an automatic dialing device configured to recognize a connection number access for obtaining a license of a prepaid card immediately by a ring tone detector, and charging two cards in the automatic dialing device. The present invention relates to an automatic dialing method that allows a call to be immediately made to another charged card when the battery is depleted by charging.

In general, the automatic dispensing device is a telephone bill prepaid service method that is authorized by the Korea Telecom (telephone switching center) to charge the phone charges to the card, and that the calculated charge is deducted from the charged exchange rate by the telephone exchange station every time the phone is called. To do this, a licensee approved by the Ministry of Information and Communication of the Ministry of Information and Communication purchased a prepaid card for the telephone charges, and the code (serial number) that allowed the prepaid card to be used when calculating the charges in the exchange system of the Korea Telecom. It adds the function to reduce the fee from the card, and based on this, a licensed operator approved by the Ministry of Information and Communication recruits members and sells the card. It saves (charges) data corresponding to the charge by wire. This is because the operator sells a large amount of telephone charge cards at one time to the user with a certain margin left on the discounted price. The discount is then sold to the operator, and the operator sells less than the user's telephone bill, so that both parties make a profit.

This can be exemplified as shown in FIG. 1, when the subscriber of the Korea Telecom (public telephone network) 1 connects and uses the telephone 2 by wire, the telephone 2 through the automatic dial device (ACR) 3. The auto dial device 3 has a specific telephone number authorized by the service provider (when this number arrives, the KTDC recognizes that the user has a built-in card purchased from the prepaid phone card service provider and charges the fee from the card. It automatically dials in advance of the desired dial phone number and then has the function to dial the desired phone number.

However, the automatic dialing device stops using the automatic dialing device 3 when the usage fee corresponding to the set number of calls is completed and uses it as a general telephone fee system, or makes a phone call to make an online deposit of the usage fee. It is inconvenient to be able to call again only after the notification is requested and a corresponding fee is input to the card, and the operator inputs (charges) the payment after confirming the payment.

In order to solve this problem, when the number of phone calls corresponding to the charged amount is completed, a method for adding a call button to a subscriber who wants to charge the operator to the automatic dial device has been proposed. As shown in Fig. 2, the dialing device having the button 5 is automatically dialed by a method of incorporating the carrier dialing call button 5 which allows the operator to automatically call the operator in the automatic dialing device 4. (Called PD group) (6). When using this, use the telephone of the number of calls corresponding to the amount prepaid using the automatic dial 6, and when the use of the prepaid rate is completed, remittance to the account of the operator in a separate online, etc., the user calls the call button ( In fact, when the operator presses the stored operator's telephone number), the operator immediately calls the operator and informs the remittance fact that the operator checks and recharges it so that it can be continuously used conveniently.

FIG. 3 is a configuration diagram of the automatic dial 6 used in FIG. 2, and the automatic dial 6 is installed between the telephone 2 and the line of the public telephone communication network 1.

The automatic dial 6 has a switch unit 7 for switching or disconnecting the line between the telephone 2 and the public telephone network 1, and connected in parallel to the telephone 2 line to detect DMP pulses. A tone detector 8, a memory unit 9 for storing a set telephone number or a digital value of a telephone number to be used, a ring detector 10 for detecting inflow of a ring signal through a public telephone communication network 1, The control unit 12 recognizes the detection signals of the tone detector 8 and the ring detector 10, controls the switching of the switch unit 7, and instructs the tone generator 11 to output the set tone signal. And the control part 12 is comprised so that the signal of the button 5 which instructs to call a specific prepaid card operator is recognized.

When the automatic dial is made as described above, the ring detector 10 recognizes this when the ring signal is input through the public telephone communication network 1, and then transmits it to the control unit 12 through the input terminal P3. The control unit 12 accordingly stops output of the signal through the output terminal P6 so that the public telecommunication network 1 and the telephone 2 are in line with each other. That is, when the telephone comes in, the controller 12 drives the switch unit 7 to be turned off so that the telephone 2 and the public telephone communication network are connected regardless of the installation of the automatic dialer 6. Therefore, the reception function of the telephone 2 functions so that there is no abnormality. However, when the user of the telephone 2 connects the auto dialer 6, it corresponds to the time of the call, and when the user of the telephone 2 picks up the handset of the telephone 2 and presses the desired party number, the tone detector 8 recognizes this and the digital signal Is converted to the control unit 12 and sent to the input terminal P4. The control unit 12 temporarily stores this in the memory unit 9, and then the tone generator 11 first transmits the prepaid card user identification number (for example, 00721) assigned to the operator of the public telephone network 1 by the operator. Command). The tone generator 11 then dials a phone number (e.g., card access number (00721) + card number (**********) + area code (##)) to indicate that the corresponding prepaid card user. First, send the card and send it to the user's input number stored in the memory unit 9. After the sending is completed, the user needs to use the card without using an additional button by attaching the auto dialer 6. Since the number is automatically sent out first, it provides convenience that can be dialed without any inconvenience in use, and when the amount of the call is exhausted, send money online to the operator, and press button (5). The control unit 12 then drives the tone generator 11 to generate a prepaid card operator calling number so as to be able to retrieve the prepaid card operator number stored in the memory unit 9. It is possible to continue using the prepaid card by charging the phone charge by connecting with the operator through the communication network (1).

However, this method can be used after the user charges by pressing the button when the amount of charge of the prepaid card is completed, and it is possible to use it. There is a problem that takes a lot of call time according to the charge. In addition, if the number of calls available by charging is exhausted, there was a problem that you can not use the prepaid card until it is recharged.

An object of the present invention is to solve this problem, by adding a ring tone detector for recognizing whether a calling call of a card charging operator is started to the function of an automatic dial device for a prepaid calling card, to facilitate the confirmation of the charge, and to provide a local service. It is to provide a dial device that can implement other service functions by adding a button to enable it.

Another object of the present invention is to provide an automatic dial method for preventing an interruption of a call due to running out of charges by embedding an extra storage card in an automatic dial device for a prepaid calling card.

Once you have confirmed that you are ready to provide an auto dialer that will allow you to use your prepaid card.

In addition, the present invention in the automatic dial method to sequentially provide the access number and the user input phone number to be recognized by the Korea Telecom Switching Office (ki) that the permission of the prepaid card operator, two cards that can be charged by the operator Set the memory unit, check which card is selected, continue the call using the selected card, and designate another card to maintain the call continuously when the call of the selected card is completed. It is intended to provide an automatic dial method of performing, including.

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

Fig. 4 is a block diagram showing the configuration of an automatic dial for use in the present invention. The automatic dial 60 is connected between the telephone 2 and the public telephone network 1,

The automatic dial 60 has a switch unit 7 for switching or disconnecting the lines of the telephone 2 and the public telephone communication network 1, and connected in parallel to the lines of the telephone 2 to detect DMP pulses. A tone detector 8, a memory unit 9 for storing a set telephone number or a digital value of a telephone number to be used, a ring detector 10 for detecting inflow of a ring signal through a public telephone communication network 1, The control unit 12 recognizes the detection signals of the tone detector 8 and the ring detector 10, controls the switching of the switch unit 7, and instructs the tone generator 11 to output the set tone signal. The control unit 12 is configured to recognize a signal of a button 5 for instructing a specific prepaid card operator and a button 5-1 for calling an auxiliary service telephone. In addition, the control unit 12 is configured to recognize the output of the connection tone detector 61 through the input terminal (P10), the connection tone detector 61 when the button (5) is pressed when the other party through the public telephone network (1) ( It recognizes that the connection of the prepaid card operator (for example, 00721) is completed (when the call permission is received) and performs a function of informing the controller 12 of this.

5 is a flowchart of the present invention, when the user picks up the handset of the telephone 2 and presses a desired counterpart number button (for example, ***-####), the control unit 12 automatically dials at this moment. It is checked whether the mode of the instrument 60 is the automatic mode (setting of the mode is recorded in advance on the card by selection at the time of initial contract) (step S1). If it is not in the automatic mode, the user input number is a free call or a toll free number rather than the use of a prepaid card (step S2). If the automatic mode in step S1, the control unit 12 transmits the set access number (00721) through which the tone detector 8 can recognize whether or not the prepaid card is recognized by the Korean telecommunication exchange that constitutes the public telephone communication network (step S1). (S3)). Then check whether the user input number is a free call or toll free number, not the use of a prepaid card (step S4). If the number of the non-prepaid card is not input in the step S2, the prepaid card usable access number is sent (step S5). Following the steps S4 and S5, the user temporarily stores the desired user input telephone number (step S6). Then check whether the connection to the exchange via the connection beep detector 61 and the confirmation is continued until the connection (step S7). Then, it is checked whether the first card charged with the call charge from the operator is selected (step S8). If the first card is selected, the number of the corresponding card is sent (step S9). If the first card is not selected in the step S8, the second card number is sent (step S10). When the card number (**********) transmission is completed in the step (S9, S10), a predetermined area code (for example ##) and the temporarily stored user input telephone number (***) -####) is sent (step S11). On the other hand, if the user input telephone number (for example ***-####) is a toll telephone number in step S2 and S4, the corresponding user input telephone number is transmitted to restrict the use of the prepaid card ( In step S12 and step S13, following the steps S11, S12 and S13, a call is made to the call connection through the exchange (step S14) .In step S7, the ring tone detector 61 is connected. The method of confirming using is an important technical idea developed in the present invention, which is designed to allow a prepaid card to be used after a predetermined time (for example, 10 seconds) in the conventional case, but the present invention is designed to enable the use of a prepaid card. In the case of confirming (confirmation of the confirmation sound at the moment recognized by the exchange so that the connection beep detector 61 is recognized, and immediately following the recognition, the card number for connection (*******) in the control unit 12 ***) and area code (##) and saved user input number (***-####) It is possible to reduce the connection time by that much (that is, in the past unconditionally sent the card number and area code and the user input number after the set time (10 seconds) unconditionally, but in the case of the present invention is a time point when the confirmation is completed, for example For example, if it is 2 seconds, the connection is made at that moment, so it is possible to connect immediately without waiting for 8 seconds to solve the inconvenience of the user's time zone).

The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention installs a ringing tone detector on an automatic dial and immediately sends a card number, an area code, and a user input phone number as soon as the exchange confirms the use of a gender card. It helps to reduce the time delay caused by using the card.

In addition, the present invention has the advantage of using a variety of functions, such as the convenience of using the two buttons to directly connect the operator when charging, the other button to select and request the service function through the operator, the charge card If the cost of charging is exhausted by using two cards, another card can be immediately selected and used to solve the anxiety of stopping the call due to the exhaustion of the card fee.
