The present invention relates to a toll collection device using a call-only mobile phone (CT2), and more specifically, when using a dedicated call-only mobile phone using an IC card such as a prepaid card or a debit card with a high density integrated circuit. Since it can be collected directly from a telephone company or a base station, it solves the problems caused by late or unpaid telephone usage charges, and further reduces unnecessary operating costs for collecting tolls, thereby providing quality services to consumers and lowering service charges. The present invention relates to a toll collection device for CT2 using an IC card that can be used.

[Background of invention]

Most homes have one or more telephones, which brings a lot of convenience to life. Also, as a new means of communication, the development of computer communication, which transmits and receives a large amount of data using a conventional telephone line, allows users to use the telephone for a long time. Users are skyrocketing. However, the use of such a telephone bill is a post-paid system that charges a certain period of usage fee in the next month. Thus, the unpaid or late arrears of telephone usage fees are seriously impaired at each telephone company, which causes problems in providing normal services. .

Late payments or unscheduled phone bills have become more serious as the spread of mobile phones, which are expensive to call, has gradually spread. However, there is a problem that it is difficult to impose practical sanctions on the users who intentionally delinquent the usage fee except for discontinuance such as call suspension, and it is impossible to collect the fee.

The late payment or non-payment of the above-mentioned telephone charges may be worsened when the call-only mobile phone (CT2 (Cordless-Telephone2)) is put into practical use. Compared with the home wireless telephone used in the conventional home, the CT2 has a limited reception function and only a transmitting function, but it can be used while moving at a low speed within a certain range, so that its use will gradually spread due to its convenience and mobility. have. In fact, it is reported that CT2 to be used can be used only in a base station installed within a radius of about 200m at a speed of about 20km or less.

In addition, from the user's point of view, to pay the telephone bill, you have to pay the telephone bill, which is mailed every month, and go directly to the bank. If the telephone bill is lost or damaged in the mail, contact the telephone company to mail another telephone bill. There was an inconvenience in that a request was made and a penalty was paid if payment was delayed.

[Purpose of invention]

The present invention has been made to solve the above problems, in particular, to prevent the late payment or unscheduled usage fee of the outgoing-only mobile phone (CT2) before the telephone call to the telephone service charge in advance by the telephone company or base station card It is to provide automatic usage fee collection device of CT2 using IC card that can prevent late payment or unpaid usage fee and make smooth collection.

Detailed Description of the Invention

Hereinafter, referring to the accompanying drawings, a detailed description will be given of the automatic charge tolling device for CT2 using the IC card of the present invention.

The CT2 usage fee automatic collection device using the IC card of the present invention can prevent arrears of telephone charges by paying the CT2 usage fee in advance before using the telephone, and further extend these functions to directly delinquent or unpaid fees to remote locations. By allowing the payment of, you can provide a very convenient function that does not have to go directly to the bank.

First, the operation state of CT2 will be briefly described with reference to FIG. 1.

When the user presses a numeric display button installed in the keypad unit 3 to make a call, the outgoing signal is inputted to the baseband processor 51b through the microcontroller 51a of the controller 5. The input signal is processed by the baseband processor 51b into a signal suitable for radio transmission, and then modulated into a high frequency signal (specific frequency band used in CT2) by the transceiver 9 and then propagated to the air through the antenna 10.

The air propagated signal is received by an antenna of a base station or telephone station for adjacent telephone relay and attempts to connect with a telephone corresponding to a telephone number called from a remote CT2. When the connection with the phone is established, you can talk to the other party with a beep.

The signal transmitted from the other party is transmitted through the telephone line and then modulated into a radio signal state by the base station or telephone station. The transmitted radio signal is inputted through the antenna 10 of the CT2, and then modulated into the original audio signal by the baseband processor 51b of the controller 5 and finally audibly output through the earphone 2. In addition, after being modulated by the baseband processor of the user's voice signal control unit 5 transmitted through the microphone 1 of the CT2, it is modulated while passing through the transceiver 9 and transmitted through the antenna 10. It is apparent to those skilled in the art that the modulation method may be any one of conventionally used analog methods or digital modulation methods (CDMA or TDMA).

According to the present invention in the conventional CT2 configured as described above, data stored on a card such as a debit card or a prepaid card with a high density integrated circuit or a credit card including a magnetic material storing data can be read and recorded. An IC card input device is further installed. 2 is a block circuit diagram of the automatic charge collection device for CT2 using the IC card according to the present invention, and it can be seen that the IC card input device 11 is connected to the microcontroller 51a of the control unit 5.

The IC card input device 11 is a mechanical part for storing a card in order to have a function of accommodating an IC card such as a prepaid card or a debit card, reading data stored in the card, and recording changed contents on the card. It includes an acceptor, a card reader / writer for reading and recording data stored in the card, a card interface unit for data communication with the microcontroller 51a of the control unit 5, and the like, which can be achieved from the prior art. . Of course, the present invention can also be configured to use a credit card with a magnetic material attached to a conventional plastic board is apparent to those skilled in the art.

The debit or prepaid card has a structure similar to that of a normal bank credit card, but has a small microprocessor (IC) that is directly internalized. It can record more information than a conventional credit card. Unlike magnetic records, which are easily damaged or altered by magnetic materials, the storage of stored data is very stable. Therefore, the use of magnetic recording cards is expected to increase rapidly. Such use can be very useful in various fields, such as debit or prepaid cards, identification documents, deposit and withdrawal of money and remittances for military purposes.

When the IC card is inserted into the IC card input device 11, the controller 5 reads the card and reads the data stored in the card through the card interface unit. Examples of stored data may be the amount of money available to the prepaid or debit card, the card number, and the like. Finally, the read data is transmitted to the base station for telephone relay through the transceiver 9, and when it is found that there is a sufficient amount as the telephone fee, a signal is output to pay the corresponding fee. The payment method of the applicable fee may be a method of paying a certain fee in advance at a telephone company or measuring a phone fee at a base station and paying the fee from a card as soon as the call ends.

3 is an external perspective view of the CT2 with the automatic charge system according to the present invention.

As shown in the figure, the overall appearance is similar to a mobile phone (mobile phone) or a future CT2, but it can be seen that a receiving groove 11a for storing the IC card is further formed under the microphone 1, and the arrow of the IC card is shown. It can be inserted by sliding it in the direction. Of course, by changing the structure of the card input device, it is possible to use a conventionally used credit card in addition to the IC card. In addition, the configuration position of the card insertion groove 11a can also be formed on the side of CT2, not below the microphone 1, and this can be changed as much as possible for convenience or aesthetics.

The effect of the automatic charge collection device of CT2 using the IC card of the present invention having the above configuration will be described in detail using the flowchart of FIG.

As is well known, since the CT2 is currently for call-only use, other means, such as a beep, can be used to receive a call request from the other party or to make a call by the user's direct needs.

When a telephone number is input by pressing a numeric button provided on the keypad 3, this input signal is input to the microcontroller 51a of the controller 5. The input signal is again modulated to an appropriate signal (typically digitally processed) by the baseband processor 51b for signal processing, and then modulated to the transceiver 9 by a high frequency signal capable of propagating to the air, thereby performing antenna 10 Is sent through.

The transmitted signal is received from the user's CT2 to the nearest station. The base station is provided with a subscriber service device and an exchange. When the telephone call request signal is received, the base station first transmits a signal requesting the payment of the service fee to the user's CT2. This transmitted signal is received by the transceiver 9 and then processed by the baseband processor 51b of the controller 5. Thereafter, the payment request signal may be output through the buzzer 8 or the voice card may be inserted through the earphone 2 as a voice signal such as inserting an IC card to pay the usage fee.

If the user wants to pay the fee for using the telephone, the user inserts the IC card into the card insertion groove 11a in the direction of the arrow as shown in FIG. When the card is inserted, the IC card input device 11 confirms the card insertion and reads the data stored in the card. The read data, for example, the remaining charge amount, card number, etc. available on the debit or prepaid card, is inputted to the control unit 5, and then modulated by the baseband processor 51b and then high frequency by the transceiver 9 After being modulated, it is finally transmitted through the antenna 10.

The base station checks the available charge from the signal received from CT2 and outputs a signal to settle the required amount of money per unit time. This signal is again input to CT2 via antenna 10. The input signal is input to the microcontroller after being processed by the baseband processor of the controller 5. The microcontroller outputs a control signal to settle the fee according to the input signal command. Of course, after calculating the user's telephone call time, it may be configured to pay the amount corresponding to the telephone use time.

The IC card input device 11 calculates the corresponding amount from the remaining balance of the IC card in accordance with the control signal output from the microcontroller 51a, and newly records the changed contents on the IC card. Both reading and writing processes are performed in the IC card input device 11.

As described above, when the settlement for the usage fee is completed in the IC card, the control unit 5 outputs a settlement completion signal. The output settlement completion signal is transmitted through the transceiver 9 after being modulated by the baseband processor 51b. When the settlement completion signal is received at the base station, the base station connects the telephone number called from CT2 using the installed exchange. When the phone is connected, the CT2 user can make normal calls.

If the IC card is not inserted into the card insertion groove 11a of the CT2 within a predetermined time by the user during the telephone call process, or if the available charge stored in the debit or prepaid card is less than the basic rate, the base station determines that the relevant fee is not satisfied. The contents can be output by voice and the communication with CT2 can be forcibly closed and returned to the standby state.

In the above description, it is described that the prepaid card or the debit card payment fee are all processed in the same process. However, the fee settlement process may be changed according to the state of the card used, and is suitable for, for example, a corresponding IC card. This can be achieved using an interface circuit.

In addition, although the automatic usage fee collection device of the CT2 using the IC card of the present invention has been described as a method of prepaying the usage fee in advance, it is also possible to use the postpaid method. That is, if there is an unpaid or overdue phone usage fee in the delivery, input the user number of the unpaid or unpaid CT2 into the main computer of the base station after the fee deadline is terminated and detect that the CT2 user attempts to make a call. You can ask in advance for the payment of unpaid fees.

If the fee is not paid, stop using the call as described above. In this case, the fourth flowchart can be easily changed by requesting payment of unpaid or unpaid fees when the payment request signal for use fee is transmitted. In addition, the present invention can be applied to a general phone or a mobile phone (mobile phone) as well as CT2.

As described above, according to the present invention, in order to prevent late payment or unpaid use of the outgoing dedicated mobile phone (CT2), by paying the fee with a card in advance at the telephone company before making a phone call, it is possible to prevent unpaid use or unpaid payment in advance and smoothly pay the fee. There is an advantage to the collection.

In addition, the user does not need a separate payment procedure by paying a telephone usage fee immediately at the time of a telephone call, and there is an advantage of reducing the telephone fee by refraining from using it when there is no usage fee.

Although the present invention has been described in detail only with respect to the embodiments described, it can be said that modifications and variations can be made within the spirit and scope of the present invention to those skilled in the art to which the present invention pertains and such modifications and changes belong to the appended claims. have.
