Description

Direct telephone for call charge of advanced payment}

The present invention relates to a prepaid call phone, and stores the card number, etc. for prepaid calls in advance in accordance with the guidance of the text message, and when used, so that the text message is skipped and only the storage number is displayed so that the number can be sent after confirmation. It's about a prepaid phone.

As shown in FIG. 1, when the hook switch 2-1 is turned on, the general telephone has a speech network 2-4 which functions to hand-call the trunk line 2-2 to the handset 2-3, and a hook switch ( 2-1) and the microcomputer 2-6 which recognizes the operation of the button unit 2-5, controls the command of the button unit 2-5, and provides a tone signal. An example of the microcomputer 2-6 may be a U.S. gyro company (TMP 47C 26N), and includes a DMT tone generator 2-7. (2-8) is an analog to digital converter. In order to make a call using a telephone prepaid card, the user picks up the handset (2-3) and presses a setting number (for example, Onse Telecom 00366) that informs the exchange office that the user has issued a prepaid card (computer carrier (Internet) Service card), as well as other domains, the prepaid card issuer (referred to as a server for convenience) with the greeting (remembered to be about 15 seconds but not limited to) issued by the prepaid card issuer. Pressing the card number (for example 7 to 20 digits) directs you to the stored voice data. When the user presses the card number listed on the purchased card, the server confirms this, and then voicely guides the user to press the password.

When the user presses a password, the server confirms it through its own database, and if it is correct, the server also prompts the user to press the desired counterpart phone number. When the user presses the counterpart phone number to call, the server checks the call time and reduces the fee. However, this method has the advantage of the low cost of using the prepaid card, but it is difficult to use because you have to operate the button by receiving the guidance by voice one by one. It becomes a factor.

In addition, the automatic telephone number transmission system is a telephone bill prepaid service that is authorized by Korea Telecom (telephone switching center) to charge the phone charges to the card, and that the calculated charge is deducted by the telephone exchange bureau every time the phone call is made from the charged card fee. . To this end, a licensee approved by the Ministry of Information and Communication of the Ministry of Information and Communication purchased a prepaid card for telephone charges (code), and the code that allowed the prepaid card to be used for the charge calculation in the exchange system of KT (serial number). After confirming that, the user can add the function to reduce the charges from the card, and based on this, a licensed operator approved by the Ministry of Information and Communication recruits members and sells the card. After checking, the data corresponding to the fee is stored (charged) on the user's card 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 illustrated as shown in Fig. 2, when the subscriber of the Korea Telecom (public telephone network) 1 connects the telephone 2 by wire and uses it, 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 allows the desired phone number to be dialed.

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 billing system, or makes a telephone 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. 3, a dialing device having a built-in button 5 is incorporated in a manner in which a dialing button 5 is provided in the automatic dialing device 4 to automatically call the operator. (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 phone number), the operator immediately calls the operator and informs the remittance fact that the operator checks it and recharges it for convenient use continuously.

FIG. 4 is a configuration diagram of the automatic dial 6 used in FIG. 3, and the automatic dial 6 is installed between the telephone line 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. In other words, regardless of the installation of the automatic dial 6, the control unit 12 drives the switch unit 7 to be turned off so that the telephone 2 and the public telephone communication network are connected. 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 first transmits the prepaid card user identification number (for example, 00721) assigned to the operator of the public telephone network 1 by the operator who has set the tone generator 11. Command). The tone generator 11 then dials a phone number (e.g., card access number (00721) + card number (**********) + area code (##)) indicating that it is a 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). Then, the control unit 12 drives the tone generator 11 so that the number of the prepaid card operator stored in the memory unit 9 can be sent to generate a prepaid card operator calling telephone number. In connection with the operator via the telecommunication network (1) accept the call charging rates is ever possible continued use of the prepaid card.

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.

The present invention is to solve this problem, an object of the present invention is to provide a prepaid call telephone that can be called like a general telephone by pressing a specific button without connecting the call using a prepaid calling card with the card server every time.
