The present invention relates to a mobile communication terminal, a system and a service control method for a prepaid service, which enables the mobile communication terminal to perform a call and charge accordingly, using a prepaid amount of money certified after the prepaid payment. It is about.

In general, conventional mobile radiotelephones such as cellular phones, Citi phones (CT-2) and personal mobile communications (PCS) generate bills or bills after the operator calculates the subscriber's (or user's) call charges (use charges). If you make a claim, the subscriber pays the billed or noticed fee, so it is a so-called postpaid settlement method.It is required to issue bills and notify them to the subscribers. As a side effect, there is a factor that induces an increase in the call rate, and the subscriber has to move to a financial institution such as a bank and pay the bill, and the bad debts that are caused by not paying the call charge are many. Is not profitable, and the creditworthiness of the individual is inferior in terms of subscribers. There was this.

1 is a block diagram illustrating a mobile communication terminal using electronic money in a mobile communication network according to an exemplary embodiment.

As shown in the drawing, the mobile communication terminal 10 having the interface 12 and the display unit 14, and electronic money for interfacing with the interface 12 when attached and detached from the mobile communication terminal 10 ( 20) and the base station 30.

The electronic money 20 is composed of an interface 12 and an input / output unit 22 for inputting and outputting signals, a control unit 24 for performing various controls, and a memory unit 26 storing a prepaid amount of money.

The mobile communication terminal using the electronic money will be described with reference to FIG. 1 as follows.

First, when a subscriber (or user) wishes to use the prepaid mobile communication terminal 10 rented or rented for free or for free or provided in a sale form, the electronic money 20 having a different face value is purchased according to circumstances. An input / output terminal is mounted in a slot of a mobile communication terminal.

To this end, the mobile communication terminal 10 forms an attachment / detachment part such as a slot, a molding, a recess, and the like so that the electronic money 20 can be attached and detached, and then interfaces through the interface 12. .

When the electronic money 20 is attached, the prepaid amount is displayed on the display unit 14 of the mobile communication terminal 10. That is, the prepaid amount recorded in the memory unit 26 of the electronic money 20 is transferred to the input / output unit 22 through the control unit 24, and the input / output unit 22 is connected to the display unit 14 through the interface 12. Mark it.

Then, the mobile communication terminal 10 performs the wireless communication through the base station 20 within the prepaid amount limit.

At this time, while the call is continuously being made, the amount of payment signal for each unit of currency is transmitted wirelessly from the base station 38 of the wireless communication provider (ie, the charging system), and the main controller of the mobile communication terminal 10 controls the interface 12. If the corrected amount is output through the control unit 24 of the electronic money 20 corrects the amount of the memory unit 26 to record as a new amount, the corrected amount is communicated through the sending unit of the mobile communication terminal 10 It is sent to the operator's base station or system and recorded.

In addition, when the balance of the electronic money 20 is less than several hundred won by the use of the mobile communication terminal 10 to be displayed as an alarm or display unit 14 using the sound alarm function or visual function of the mobile communication terminal 10. When the user recognizes this to enable the exchange of the electronic money 20.

When the electronic money 20 is mounted on the mobile communication terminal 10, the amount of the electronic money 20 is displayed on the display unit 14, and the electronic money 20 is also displayed on the base station or system of the telecommunication service provider through the transmitter of the wireless telephone 10.

After determining whether the representative number received from the billing and authentication server and the number of the subscriber's mobile communication terminal is consistent with the registered matters (S35), if it is determined that they do not match, guides the subscription of the prepaid billing service member (S36), If it is confirmed in step S35 that it matches, the authentication is transmitted to the exchange (S37).

Then, the exchange receiving the authentication information inquires the number of the called terminal to the calling terminal (S38), and if the calling terminal enters the number of the called terminal (S39), the switching to the billing and authentication server in the Query the available time of the called terminal (S40).

At this time, the billing and authentication server calculates the callable time of the called terminal and transmits it to the exchange (S41), and transfers the call to the called terminal from the exchange confirming the callable time of the called terminal (S42). Then, the call between the calling terminal and the called terminal is performed (S43).

From the exchange, it is determined whether or not the time available for the call according to the call amount of the called terminal is exceeded (S44). Determines that the operation has been stopped and transmits the call history charging and authentication server to be described later (S46). If it is determined that the available time has been exceeded, the exchange stops the call (S45), and the exchange transmits the call history to the billing and authentication server (S46).

As can be seen from the description of the flowchart, a person who has subscribed to a service conventionally accesses a registered 080-XXX-XXXX number, and if the terminal is a registered terminal, a call is possible and the terminal is not registered. There is no currency available. If you registered your password when you applied for subscription, you can enter your password on your device to authenticate your password. When the authentication is completed, the subscriber may re-enter the desired calling party number and if the called number is not the outgoing call number, the subscriber may call. Call time is limited to the amount already paid.

It is a service that makes it possible. In this case, if the call exceeds the available time, the call is disconnected. If the call is interrupted within the call time limit, the call charge is calculated for the duration of the call and the call charge is deducted from the available balance before the call. Means.

In this case, when the 080 service is used, the caller is charged in the form of the caller's bill, so the operator who opened the 080 number bears the call charge. The burden of such a carrier adopts the operator settlement method between the carriers, and provides a system that can pay the user's call charges using the service by the settlement method.

However, in the above-described prepaid service method as shown in FIG. 2, the billing and authentication server performs a call within the amount already paid by the user and performs the billing according to the call details. The billing and authentication server starts charging each time a call is generated, and the charging and authentication server notifies the exchange whether the account is charged and whether the call is started or terminated, so that the authentication and the billing result is generated at each occurrence of the prepaid mobile terminal in the entire mobile communication system. There is a problem in the operational efficiency that must be delivered to the mobile communication terminal.

The present invention has been made to solve the above-described problems, and after requesting a prepaid service, the prepaid service to charge the prepaid amount by one service authentication from the prepaid authentication system of the wireless communication network, to use the prepaid service Its purpose is to provide a mobile communication terminal and a service control method thereof.
