The present invention relates to a phone bill (Phone Bill) service using infrared rays, and more particularly, to a method of receiving a simple authentication through a simple authentication algorithm when making a small payment and a method for providing a phone bill by the authentication method.

The currently used phone bill service uses a mobile communication terminal to make a call to a specific phone number assigned to a vending machine. The authentication result is transmitted to the vending machine and stored in a predetermined database, and the vending machine is controlled according to the authentication result. If the vending machine is operated, the user can receive the goods from the vending machine, and the price for the goods provided by the user is billed in addition to the telephone fee of the user's mobile communication terminal.

In the early stages of payment service using infrared, the credit card information embedded in the mobile communication terminal with the infrared module is transmitted to the credit card checker with the infrared module in the infrared and the online authentication is used to make the payment. . However, despite the payment of a small amount (for example, vending machine, gas station, game room, etc.), there is a disadvantage that a relatively large amount of data transmitted and received by sending credit card information and performing the authentication process and takes a long time in the transaction.

Accordingly, in order to improve the payment service using infrared rays, when a phone bill service is combined and a vending machine transmits a mobile identification number (MIN) of the mobile communication terminal through an infrared link, the vending machine transmits the mobile identification number. By authenticating that the mobile communication terminal is a normal subscriber with a unique number of the terminal, a normal subscriber can consider a service method of claiming the sum of the charges to the mobile terminal after providing the goods.

However, the unique number of the mobile terminal can be changed by anyone who knows only the code that can drive the Number Assignment Module (NAM) programming, and the malicious user can change the unique number of the mobile terminal of another user. It was having difficulty in commercialization because it was able to randomly input to the terminal of the infrared payment service.

The present invention has been invented to solve the above problems, and an object of the present invention is to determine whether the normal user in the vending machine without the introduction of a separate complex authentication algorithm authentication method for providing a phone bill service using infrared and its authentication method It is to obtain a method for providing a phone bill service.

According to a first aspect of the present invention, there is provided a method for providing a phone bill service using infrared rays, the method comprising: a) attempting a call connection by a mobile communication terminal having a unique number set; b) setting the unique number to a parameter value for performing authentication by infrared communication when the mobile communication terminal succeeds in call connection; c) the mobile communication terminal transmitting the parameter to the automatic product providing apparatus when the mobile communication terminal and the automatic product providing apparatus each having an infrared module for performing the infrared communication are connected by infrared rays; d) comparing and searching, by the automatic product providing apparatus, the parameter with a unique number of a bad credit mobile terminal stored in a predetermined database; And e) if the comparison search result does not match in step d), the automatic goods providing device is switched to an operable state, and the goods selected by the mobile communication terminal are discharged, and the transaction details are set to the predetermined value of the automatic goods providing device. And storing the transaction history periodically to a management server through a mobile communication network. If the mobile communication terminal fails to connect a call, the parameter value is not specified. It is characterized by including.

More preferably, when changing the unique number of the mobile communication terminal to another predetermined unique number, characterized in that it further comprises the step of deleting the unique number of the mobile communication terminal specified by the parameter value.

Therefore, according to the present invention, the phone bill service using infrared rays can be activated.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 illustrates a vending machine transaction method using a mobile communication terminal in which authentication is completed according to an embodiment of the present invention.

Referring to FIG. 1, an automatic product providing device 200 in which an infrared module is embedded in an infrared ray using a mobile communication terminal 100 in which user authentication is completed and an infrared module is built according to a method to be described below will be referred to as a vending machine. ). The vending machine 200 includes a CDMA unit, an integrated control unit, an RF unit, an infrared module, a hair coin unit (Mobile Coin), and a bad credit database (Black List DataBase).

When the connection is completed, the mobile communication terminal 100 transmits an IrDA_MIN parameter to the vending machine 200, and the vending machine 200 receiving the IrDA_MIN parameter receives the credit of the vending machine based on the IrDA_MIN parameter. Check whether or not it corresponds to a bad subscriber stored in the bad person database. If the user who uses the mobile communication terminal 100 is a normal subscriber, the mobile terminal 100 is switched to an operable state. That is, the operable lamp is turned on in the selection button so that the goods of the vending machine are provided according to the user's selection. However, when the user is a bad subscriber, the vending machine operation lamp is not turned on and the user cannot receive the goods.

The user selects a desired product and receives the product from the vending machine. At the same time, the vending machine transmits the transaction details to the micropayment company 300.

The vending machine 200 is periodically connected to the mobile communication network to transmit the usage information information to the micropayment company 300, that is, the server of the vending machine management operator in the present embodiment by wireless or wired.

The micropayment company 300 calculates the received information and transmits it to the billing server 500. The billing server 500 receives the goods from the micropayment, that is, the vending machine based on the settlement result of the usage record information received from the micropayment company 300 for the mobile communication terminal users who incurred the charges for the provided goods. In addition to storing the charge in a predetermined database to charge the fee together with the mobile communication terminal usage fee and sends a confirmation message to the micropayment provider (300).

The micropayment provider 300 receiving the confirmation message transmits the transaction details to an application service provider (ASP) 400 and manages the transaction details, and transmits a confirmation message about the transaction details to the vending machine 200. The ASP server 400 performs the function of providing and managing the sales amount, inventory information, and operation information for each food and vending machine, and immediately identifying and notifying whether the operation vending machine is broken or abnormal.

2 is a flowchart illustrating an authentication method according to an embodiment of the present invention.

Referring to FIG. 2, prior to providing a phone bill service using infrared rays to a mobile communication terminal, a memory address is first designated to a memory of the mobile communication terminal in order to generate a parameter called IrDA_MIN (S100). . A unique number (MIN) of the mobile communication terminal is set at the designated memory address (S150). The setting of the unique number of the mobile communication terminal is not directly made by the user, but is operated only at the opening of the mobile communication terminal through a dealer, and it is common to make a confirmation call for correct opening confirmation. Therefore, if the call connection is successful by requesting the call to the mobile communication terminal set the unique number, the unique number in the IrDA_MIN parameter for the phone bill service using the infrared ray of the present invention while the user of the mobile terminal does not recognize Is set.

In other words, in consideration of the use of a mobile communication terminal by an illegal user, the present invention determines whether a call connection is successful by requesting a call connection to the mobile communication terminal (S200). If the call connection is not successful, since the mobile communication terminal is not authenticated as a normal user, the memory address of the stored IrDA_MIN parameter is left as an empty space (S400).

However, if the call connection is successful, the unique number (MIN) of the mobile communication terminal is copied to the memory address of the IrDA_MIN parameter to generate the IrDA_MIN parameter, and then use the IrDA_MIN parameter for the infrared phone bill service. (S300).

The mobile communication terminal stored in the memory address of the IrDA_MIN parameter when a new input or change of the unique number (MIN) of the mobile communication terminal, that is, the mobile communication terminal is reset by programming the unique number of the mobile communication terminal. Delete the unique number of (S600). This is to prevent an error occurring between the unique number stored in the memory address of the IrDA_MIN parameter and the unique number of the mobile communication terminal that occur if the unique number of the mobile communication terminal is not deleted.

After deleting the unique number of the mobile communication terminal stored in the memory address of the IrDA_MIN parameter and attempting to connect a call to the mobile communication terminal successfully, the new or changed unique number of the mobile communication terminal is added to the memory address of the IrDA_MIN parameter. Copied.

When the mobile communication terminal authenticated by the above-described method is connected to an automatic product providing device having an infrared module, which is an embodiment of the present invention, that is, a vending machine according to an embodiment of the present invention, the mobile communication terminal may set the IrDA_MIN parameter. Transfer to the vending machine (S700, S710).

When the IrDA_MIN parameter is input from the mobile terminal to the vending machine, the vending machine compares the IrDA_MIN parameter with a list of bad credit traders stored in the black list database of the vending machine. Judging by the user. Thus, the vending machine is in an operable state so that the product can be selected by the user (S720). When the product is selected by the user, the transaction details are stored in the vending machine (S730).

The stored transaction history is periodically transmitted to the management server using a wired or wireless network, the management server stores the transaction history, and the bill of the mobile terminal is provided together with the billed amount of the product (S740, S7520). . The management server includes the above-mentioned micropayment company, billing server, and ASP server.

Embodiment of the present invention is only one embodiment, of course, many modifications and variations of the components of the present invention without departing from the gist of the present invention, of course, the present invention is not limited to the embodiment. .

As described in detail above, according to the method for providing a phone bill using infrared rays of the present invention, a mobile communication network does not directly use the set unique number (MIN) of the mobile phone terminal for infrared bill billing. By using the unique number of the mobile communication terminal which is confirmed to be a normal subscriber and successfully connected to the phone bill, it is difficult to prevent the illegal transaction by using the unique number. It is effective to contribute to the activation of the phone bill transaction using infrared rays by additionally setting simple transmission parameters to the mobile communication terminal without introducing.
