The present invention relates to a mobile communication prepaid fee charging system and method using a public telephone. More specifically, a payphone is used to connect to an ARS (Automatic Response Service) system with a specific access number using a payphone and to charge a prepaid fee for a mobile communication service within the calling balance of a coin or calling card. The present invention relates to a mobile communication prepaid fee charging system and method.

As the electronic and communication technologies have made rapid progress, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, and can provide a service regardless of time and place. In recent years, a wireless Internet service that provides an Internet communication service to a user of a mobile terminal through a wireless communication network has emerged.

Accordingly, subscribers of mobile communication service can freely move and talk with the other party anytime and anywhere using wireless communication service, and various information necessary for life through wireless internet service such as news, weather, sports, gift , Exchange rates or traffic information may be provided in various forms such as text, voice, or image.

However, as the wireless call service and the wireless Internet service are popularized, communication rates also increase. Accordingly, in order to relieve the burden of heavy telecommunication charges of subscribers using mobile telecommunications services, each mobile telecommunications carrier or a separate telecommunications carrier is changing the billing method to lower service usage fees, but the effectiveness of the telecommunications fees is low for subscribers. Still a big burden.

Meanwhile, in order to secure more members, each mobile telecommunications provider or a separate telecommunications provider is involuntarily subscribing even a minor who is not economically capable as a member of the company. As a result, social problems such as disagreement with parents due to excessive communication charges of minor subscribers are emerging.

A prepaid plan is a method that has been addressed to solve this problem of excessive communication charges. The prepaid plan usually pays a certain amount of communication fee in advance on a monthly basis and uses a mobile communication service within a limit of the previously paid communication fee. That is, when the prepaid fee prepaid is exhausted, the origination restriction is first set in the user's mobile terminal. Therefore, a user who has set a calling limit exceeding a previously paid rate limit may use a mobile communication service, in particular, a calling service after recharging the communication rate again to release the set calling limit.

Current charges for recharging telecom rates include subscribers visiting a customer center or reseller, or making a phone call to an Internet payment system, a customer center or an automatic response service (ARS) system, and then using a credit card or bank transfer. If you pay a certain amount, it will recharge the prepaid amount. Alternatively, when a subscriber visits a customer center or an agent in advance and purchases a prepaid card, and the communication fee is exhausted, the subscriber recharges the communication fee by using the prepaid card.

However, it is not only cumbersome and time-consuming for the user to visit the customer center, dealer, or bank in order to recharge the communication charges. You must open a credit card or have a bank account.

In particular, minor subscribers, which are the main targets of prepaid plans, are unable to open a credit card and must visit a customer center, dealer, or bank in person.

In addition, in the current payment method for charging a communication fee, there is a need to go through a verification process. In particular, the identity verification process in the method of charging the communication fee on the Internet is performed through an important file such as a public certificate, so when charging the communication fee in a public place such as a PC room or a library, the risk of personal information leakage increases. There is a tendency for users to avoid charging for communication charges in public places.

Due to these shortcomings, a method of recharging communication charges using a visit to a customer center, a dealer, a bank, or the Internet is not widely used, which is a major obstacle to the settlement and development of a prepaid plan.

In order to solve this problem, the present invention relates to a mobile communication prepaid fee charging system and method using a public telephone. More specifically, a payphone is used to connect to an ARS (Automatic Response Service) system with a specific access number using a payphone and to charge a prepaid fee for a mobile communication service within the calling balance of a coin or calling card.

At this time, the call balance check of the public telephone 110 may be executed by the control unit 240 of the telephone exchange 124 (S304).

The subscriber who listened to the announcement message inputs the mobile terminal number and the desired amount of charge using the key button of the payphone 110. When the mobile terminal number and the charge amount are input, the public telephone 110 transmits the current phone balance to the wired public telephone network 120 (S306).

The wired public telephone network 120 checks the call balance and the charge amount by using the telephone exchange 124, and determines whether the charge amount does not exceed the call balance (S308). If the charged amount exceeds the call balance, the public telephone 110 transmits a guide message requesting recharge not possible and re-entering the charged amount (S310), and the subscriber who receives the guide message re-enters the charged amount ( S312).

Here, in performing steps S310 and S312, the wired public telephone network 120 transmits a guide message requesting additional input of coins in addition to the guide message requesting re-entry of the recharge amount, so that the subscriber receives the pay phone 110. It is also possible to add additional coins to the.

If the recharge amount is re-entered or the coin is additionally input through the S312 step, the telephone exchange 124 re-performs the step S308 of checking the remaining balance and the recharge amount.

If it is determined in step S308 that the charge amount does not exceed the call balance, the telephone exchange 124 transmits a charge request message to the mobile communication network 130 to request the prepaid charge. At this time, the charge request message includes the mobile terminal number and the charge amount information (S320).

The intelligent network switch 134 receiving the charge request message of the prepaid fee through the gateway 132 transmits the mobile terminal number to the charging server 136 (S322), and compares it with the mobile terminal number stored in the charging server 136. It is checked whether or not it is a valid subscriber (S324).

When the subscriber confirmation is completed, the intelligent network exchange 134 transmits a charge request message for requesting the subscriber to charge the prepaid fee to the charging server 136 (S326), and the charging server 136 transmits the remaining charge data of the subscriber. The prepaid fee is charged by updating the remaining charge data by adding the requested charge amount (S328).

Here, after the subscriber verification is completed, a short message including a call-back URL requesting confirmation of charging of the prepaid fee is generated from the short message center 138 to the mobile terminal 150, and the short message including the callback URL is included. When the mobile terminal 150 receiving the message transmits the charge confirmation message by using the 'confirmation' button or the like, the intelligent network switch 134 may be configured to transmit the charge request message to the charging server 136.

When charging of the prepaid fee is completed, the charging server 136 transmits the charging result to the intelligent network switch 134 (S330). Upon receiving the charging result, the intelligent network switch 134 requests generation and transmission of a short message to inform the charging of the prepaid fee to the short message center 138 in order to notify the mobile terminal 150 that the prepaid fee is charged ( S332).

The short message center 138 transmits the created short message to the mobile terminal 150 through the wireless base station 140 (S334).

Here, steps S332 and S334 for transmitting the result of charging the prepaid fee to the mobile terminal 150 may be omitted. However, when the fee is charged in the form of a gift or the like by a user other than the user of the mobile terminal 150 in which the prepaid fee is charged, it is more preferable to send a short message to notify the user of the mobile terminal 150 that the charge is charged. desirable. It is also possible to set whether or not to send a short message to a user who has charged the prepaid fee.

The intelligent network switch 134 transmits the prepaid charge charging result to the telephone exchange 124 at the same time as the execution of step S332 of delivering the prepaid charge charging result to the short message center 138 (S336) and the telephone exchange 124.

When the mobile subscriber selects the prepaid fee charging by pressing '1' by using the key button of the public telephone 110 (S412), the ARS system 122 provides a guide message requesting the input of the mobile terminal number. . For example, the message "Enter the number of the cell phone to charge, press the # button.", Where the '#' button is used to inform the completion of the input of the mobile terminal number, '*' Various modifications, such as a button, are possible, but the following description of the present invention will be limited to '#'.

The input of the '#' button is for distinguishing from the previous 10-digit mobile terminal number when the 11-digit mobile terminal number is input because the current mobile terminal number system is not unified to 10 or 11 digits. In this case, in addition to the mobile terminal number, a serial number or a resident registration number of a subscriber, which is set in advance by the mobile communication service provider, may be used (S420).

The subscriber receiving the guide message inputs a 10-digit or 11-digit mobile terminal number and a '#' button by using a key button of a pay phone (S422).

When the input of the mobile terminal number is completed, the ARS system 122 transmits a guide message requesting the input of the charge amount (S430), and the subscriber inputs an amount to be charged using the key button (S432). In this case, the amount of money inputted by the subscriber is corrected using the '#' button. If the subscriber does not use the '#' button or the like to indicate the completion of the recharge amount, the ARS system 122 costs 100 won or 1,000 won when the subscriber presses the key button to enter 10,000 won. This is to prevent this because it can be mistaken for input.

Here, if it is determined by the telephone exchange 124 that the call balance of the public telephone 110 is not 10,000 won, and transmits a message that can not be recharged and request to re-enter the charge amount (S440), the subscriber pays the charge amount It is input again (S442).

If the telephone exchange 124 checks the charge amount input in steps S432 and S442 and does not exceed the call balance of the public telephone 110, a message indicating that the subscriber is being confirmed is transmitted. Then, subscriber authentication is performed using the intelligent network switch 134 and the charging server 136 (S450).

When the subscriber authentication is completed, the information for re-confirming the user and the charge amount of the mobile terminal 110, such as "charges 5,000 won by Hong Gil-dong's mobile phone. If it is correct, press 2 if you want to re-enter." The message is transmitted (S460).

When the subscriber completes reconfirmation of the user and charge amount of the mobile terminal 110 and inputs '1' (S462), the ARS system 122 provides a message indicating that it is charging (S470), and the intelligent network switch 134 ) Charges the prepaid amount of the subscriber account through the billing server 136. When charging is complete, the ARS system 122 informs you that the charging is completed, "KRW 5,000 has been charged to 010-1234-5678." And a menu selection guide message, such as another charge or balance inquiry, to confirm additional work of the subscriber (S480).

When the subscriber inputs a button for termination (S482), the ARS system 122 transmits a guide message indicating termination, and terminates the call connection (S490).

In the above process, it is also possible to add a separate password input process after steps S420, S430 and S460, the telephone exchange 124 and the intelligent network switch 134 and the billing server 136 before step S430 By interlocking, "the number of the inputted cell phone is that of Hong Gil-dong. If it is correct, press 1, if you want to re-enter 2," you can add a step to confirm the user of the mobile terminal 150.

In addition, steps S460 to S470 of reconfirming the user and the charge amount of the mobile terminal 110 may be omitted.
