Abstract

PURPOSE: A method for providing a phone bill service using infrared rays is provided to present an authentication method to provide a phone bill service using infrared rays without the necessity of a special, complicated authentication algorithm. CONSTITUTION: A parameter 'IrDA_MIN' for a phone bill service using infrared rays is created and stored in a mobile terminal containing an infrared ray module(S100). If the mobile terminal is connected with a vending machine having an infrared ray module(S700), the mobile terminal transmits the IrDA_MIN parameter to the vending machine(S710). If the IrDA_MIN parameter is inputted to the vending machine, the vending machine compares the IrDA_MIN parameter to a list of bad credit dealers stored in a black list database. In case that a matched MIN(Mobile Identification Number) is not detected, the vending machine is activated so that the user can select goods(S720). If the user selects desired goods, the vending machine stores the transaction details(S730). The vending machine transmits the stored transaction details to a management server(S740). The management server adds the price of the goods to the bill of the mobile terminal(S750).

Description

How to provide phone bill service using infrared light {METHOD FOR PROVIDING PHONE BILL SERVICE BY USING INFRARED}

The present invention relates to a phone bill service using infrared rays, and more particularly, to a method of easily receiving authentication through a simple authentication algorithm when making a small payment and a method of 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: generating a parameter inside the mobile communication terminal; b) transmitting the parameter from the mobile communication terminal to the automatic product providing device when the mobile communication terminal and the automatic product providing device each having an infrared module are connected by infrared rays; c) comparing and searching the parameter with a unique number of a bad credit mobile terminal stored in a database by the automatic goods providing apparatus to which the parameter is transmitted; And d) if the result of the comparison search in step c) does not match, the automatic goods providing device is switched to an operable state, the goods are discharged, and the transaction details are stored in a predetermined memory of the automatic goods providing device, and the transaction information It characterized in that it comprises the step of transmitting periodically to the management server, the step a) is a-1) the mobile communication terminal set the unique number of the mobile communication terminal attempting a call connection; And a-2) if the mobile communication terminal succeeds in call connection, using the unique number of the mobile communication terminal as the parameter value, wherein step a) is performed by the mobile communication terminal to call connection. If unsuccessful, further comprising the step of not specifying the parameter value.

More preferably, the step a) may further include the step of deleting the unique number of the mobile communication terminal specified as the parameter value when the unique number of the mobile communication terminal is changed to another predetermined unique number. .

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, the user authentication is completed according to the above-described method, and the mobile communication terminal 100 having the infrared module is connected to the vending machine 200 having the infrared module embedded therein. 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 that receives the IrDA_MIN parameter checks whether or not it corresponds to a bad subscriber stored in the credit bad user database of the vending machine. . 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.

At the same time the user selects a desired product and receives the product from the vending machine, the vending machine transmits the transaction information 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, the confirmation message is transmitted to the small payment provider 300 at the same time as the charge is stored in a predetermined database to be charged together with the mobile terminal usage fee.

The micropayment company 300 receiving the confirmation message transmits the transaction information to the application service provider (ASP) 400 and manages the transaction information, and transmits the confirmation message about the transaction information 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, in order to generate a parameter called IrDA_MIN for a phone bill service using infrared rays in a mobile communication terminal, a memory address is designated in a memory of the mobile communication terminal (S100). After the memory address is designated, a unique number (MIN) of the mobile communication terminal is set (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. Accordingly, the IrDA_MIN parameter for the phone bill service using the infrared light of the present invention is generated without the user's knowledge.

However, in consideration of the use of a mobile communication terminal by an illegal user, the present invention determines whether the 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, and then the IrDA_MIN parameter is used 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.

When the unique number of the mobile communication terminal stored in the memory address of the IrDA_MIN parameter is deleted and used for call connection to the mobile communication terminal, the unique number of the new or changed mobile communication terminal is copied to the memory address of the IrDA_MIN parameter again. .

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. Therefore, the vending machine is in an operable state so that the user can select a product (S720). When the product is selected by the user, the transaction details are stored in the vending machine (S730).

Periodically transmitting the stored transaction history to the management server, and stores the transaction history in the management server and give the billed amount of the product to the bill of the mobile communication terminal (S740, S7520). The management server includes a micro settlement company, a billing server, and an ASP server to be described later.

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 solving the authentication problem for the malicious hijacker caused 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, the illegal transaction can be prevented as well as separate complicated authentication. By additionally setting simple transmission parameters in the mobile communication terminal without introducing an algorithm, it contributes to the activation of the phone bill transaction using infrared rays.
