Description

Cell Phone with Non-contact IC Chip Controllable {Cellular Phone Having Use Controllable Contactless IC Chip}

(Technology)

The present invention relates to a mobile phone, and more particularly, a mobile phone including a contactless IC chip and an RF antenna in which user unique identifier information is recorded, and which can control the operation state of the contactless IC chip through mobile communication. It is about.

(Background)

As is widely known, a smart card in which an IC chip including a microprocessor, an operating system, a security module, and a memory is inserted to have a storage function, a calculation function, and a security function is used for communication, finance, education, administration, transportation, etc. In many fields, it is widely used as a means of recording information, identifying and paying.

Smart cards can be classified into various categories according to their classification criteria, but IC chips can be classified into contact cards, contactless cards, and combined cards, depending on how data is read from the card.

A contact card refers to a card in which a card is activated by contacting the contact of the card with the contact of the interface device when the contact card is inserted into an interface device (billing machine, card reader, reader, etc.) that accommodates the contact card. Computation and memory elements required for the information processing function are the same as the contact card, but the power supply for driving the non-contact IC chip in the card is provided through the coil (RF antenna) in the card and the electromagnetic induction for communication with the interface device. It refers to a card using a type (induction electromotive force), and a combined card supports both a contact card and a contactless card, and a representative Combi card can be shared by a contact / contactless card in one card. It is a card configured to share the possible parts with each other.

Traffic card, one of the applications of smart card, was mainly used as a non-contact prepaid card in the form of a plastic card with a contactless IC chip and an antenna. The prepaid non-contact traffic card is prepaid to be charged at the charging station. The amount was stored (charged) on the card, and whenever the vehicle was used, the card was contacted with a card reader (traffic toll) to wirelessly communicate so that the amount was reduced from the stored amount. As such, the prepaid electronic money in the form of a plastic card has a inconvenience in that a user must separately prepare and carry a card, and have to go to a charging station in order to charge the amount of money in the card.

Under these circumstances, a credit card with a built-in non-contact IC chip, which allows postpayment of transportation charges by credit, has emerged, while the smart card is not in the form of a plastic card. Techniques such as embedding in essential mobile phones have been proposed.

By providing the smart card-equipped mobile phone as described above, it is possible to replace the traditional plastic card type traffic card with a mobile phone, thereby eliminating the inconvenience of having to separately prepare a traffic card, and adopt a postpaid agent. In this case, it is possible to conveniently charge or settle the used amount using mobile communication of a mobile phone without visiting a charging station.

If postpay is applied to payment by a mobile phone with a contactless payment function, the card reader recognizes the user's unique identifier information through mobile communication with the mobile phone which is accessed, and manages the server (mobile carrier or financial company, etc.) with the amount information. ), And the management server collects the amount of use for a predetermined settlement period (eg monthly) and bills the user.

When postpay is adopted for contactless payment of a cellular phone, a means of limiting abnormal use of payment is required. That is, when the user of the mobile phone does not pay the post-paid usage fee on the payment date and needs to suspend the use, the user needs to report the loss of the mobile phone and restrict the use of others. There is a need to suspend a payment function of a specific mobile phone temporarily or permanently, such as when a user cancels the use of a payment service.

Until now, usage control for mobile phones with such a contactless payment function has been performed by blacklisting the identification code of the mobile phone whose management server (server managing the corresponding payment) needs to stop using the payment function. It is constructed and sent periodically to the card reader (toll collector) or irregularly, and the card reader is read when the identification code read from the mobile phone corresponds to the usage restriction. It has been managed in a way that refuses to pay using the mobile phone.

However, the above-described conventional blacklist management system has a problem in its operation. One of the typical problems is a cost problem in that a larger number of users increases the blacklist data so that a larger capacity of memory is required to store a larger amount of blacklist data for each card reader. In particular, the blacklist data is inevitably produced because the user must blacklist the discarded model every time the user changes the mobile phone model so that the blacklist data is mass produced, thereby increasing the burden of increasing the memory capacity of the card reader.

Another problem is that there is a limit to upgrading new blacklist data in real time to many card readers when a new blacklist target occurs. In other words, the blacklist data related to the monthly fee overdue can be upgraded by being transmitted to the card reader at a fixed time point every month.However, the blacklist data update due to the sudden report of lost mobile phone can be used to update the card. Since it is difficult to transmit to the reader in real time, there is a problem that it is difficult to prevent fraudulent payment for a period from the cell phone loss report until the blacklist data is upgraded to the card reader.

In order to solve such a problem, the present inventors describe the invention of controlling short-term settlement by short-circuit (shorting) an IC chip in a smart card that is detachably mounted on a mobile phone. It was proposed as a patent application No. 10-2002-0070776 (filed November 14, 2002) under the name of '.

The object of the present invention is that the contactless IC chip and the RF antenna having the user's unique identification information are integrally provided with the cellular phone, so that the cellular phone can be used as a payment means in addition to mobile communication. It is to provide a mobile phone that can be controlled through the mobile communication of the mobile phone.

According to the present invention, there is provided a cellular phone in which a contactless IC chip electrically connected to the CPU of the cellular phone and having unique identifier information and an RF antenna electrically connected to the contactless IC chip are integrally provided.

According to a feature of the present invention, the non-contact IC chip includes a short circuit switch circuit integrally. The short-circuit switch circuit selectively short-circuits the contactless IC chip as the CPU selectively interrupts power supply to the contactless IC chip according to a usage control signal received from a management server through mobile communication. Switch between enabled and disabled state.

Hereinafter, with reference to the accompanying drawings will be described in detail a mobile phone according to the present invention. The following embodiments are merely illustrative of the mobile telephone according to the present invention, and are not intended to limit the scope of the present invention.

1 is a schematic block diagram of a mobile telephone according to the present invention, and FIG. 2 is a conceptual diagram of a contactless IC chip applied to the mobile telephone according to the present invention.

Referring to Fig. 1, the cellular phone 1 to which the present invention is applied is basically a CPU (controller 10) for controlling overall mobile communication functions, and a key input unit for inputting various data and commands, similarly to a conventional cellular phone. 20, a monitor 30 (e.g., an LCD) for displaying various types of information on the use of the mobile phone, a memory 40 for storing programs and various data input and output related to the overall operation of the mobile phone, and a base station to move with the base station; Communication unit 50 including an antenna and a duplexer to enable communication, an audio unit 60 having a speaker and a microphone for a call, and a power supply unit 70 for supplying power.

In addition, according to a feature of the present invention, the contactless IC chip 80 having unique identifier information is integrally installed as a package type in the mobile phone 1, and the RF antenna 90 is embedded in a suitable place such as a battery or a casing. have. The contactless IC chip 80 is electrically connected to the CPU 10 and the RF antenna 90 through the terminals 81.

Due to the presence of such a contactless IC chip 80 and the RF antenna 90, the mobile phone 1 of the present invention has additional functions such as payment of various charges (eg, transportation charges) in addition to the unique mobile communication function. .

That is, when the mobile phone 1 of the present invention is paid close to the interface device (2: card reader, toll collector, reader, etc.), the user can be settled by the unique identifier information embedded in the contactless IC chip 80. Is recognized and payment is realized based on the recognized user information, and the charged fee is, for example, a credit card bill or telephone charge through a management server (server that manages billing such as a credit card company or a mobile carrier). Billed by invoice.

The contactless IC chip 80 is switched between the enabled state (activated state) and the disabled state (deactivated state) by the use control signal transmitted from the management server to the cellular phone 1 through mobile communication. That is, the operation of the contactless IC chip 80 is controlled through mobile communication, and by such control, the use of the contactless IC chip 80 (eg, use for payment) by an abnormal user is restricted.

For example, when a user who pays a fee using the cellular phone 1 of the present invention needs to stop the payment function by overdue without paying the fee, the user reports the loss of the cellular phone. It is necessary to suspend the use of functions such as payment by the contactless IC chip 80 temporarily or permanently, for example, when it is necessary to block an improper use by the learner or when the user cancels the use of the payment function. If there is, the management server transmits a usage control signal to the corresponding cellular phone via mobile communication, and the CPU 10 receives this usage control signal and selectively selects the contactless IC chip 80 into a usable state and an unusable state. By switching to, the abnormal payment by the cellular phone 1 is blocked.

Such control of the non-contact IC chip 80 selectively short-circuits the non-contact IC chip 80 in accordance with the presence or absence of power supply to the non-contact IC chip 80, thereby selectively activating or By deactivating it.

Referring to the example of FIG. 2, the short-circuit switching circuit 82 is integrally included in the non-contact IC chip 80, and the CPU 10 and the RF antenna are provided at the terminal 81 of the non-contact IC chip 80. 90) are connected. The contactless IC chip 80 is switched to active (normal state) or inactive (short state) depending on whether or not the CPU 10 supplies power to the contactless IC chip 80.

For example, when the usage control signal transmitted from the management server to the mobile phone 1 through the mobile communication in the normal state is the available signal, the CPU 10 receiving the available signal supplies power to the contactless IC chip 80. And supplying power to the contactless IC chip 80, the short-circuit switching circuit 82 keeps the contactless IC chip 80 in a non-shorted state, and then the RF antenna 90 is driven by its induced electromotive force. Communicate with the interface device 2 to execute the payment function. In this case, when it is necessary to stop the payment function of the contactless IC chip 80, the management server transmits a usage control signal for restricting the use of the payment function of the contactless IC chip 80 to the corresponding mobile phone, and disables the control signal. The CPU 10 receives a command to cut off power to the contactless IC chip 80, and when the power is cut off from the contactless IC chip 80, the short-circuit switching circuit 82 brings the contactless IC chip 80 into a short circuit state. Then, even if the mobile phone 1 approaches the interface device 2, the payment operation is not performed.

On the contrary, when the use control signal is a usable signal, the CPU 10 instructs not to supply power to the contactless IC chip 80, and if the power supply is not supplied to the contactless IC chip 80, the short-circuit switching circuit 82 is executed. The non-contact IC chip 80 can be kept in a non-short state so that a normal payment function can be executed. In this case, when it is necessary to stop the payment function of the contactless IC chip 80, the management server transmits a usage control signal for restricting the use of the payment function of the contactless IC chip 80 to the mobile phone, and disables the control signal. The CPU 10 receives a command to supply power to the contactless IC chip 80, and when power is supplied to the contactless IC chip 80, the short-circuit switching circuit 82 maintains the contactless IC chip 80 in a short circuit state. The payment will not work.

In FIG. 2, reference numeral 83 denotes a diode. Even when the non-contact IC chip 80 is in a short circuit due to the action of the short switching circuit 82, current is reversed due to the strong induced electromotive force of the RF antenna 90. To prevent it from being released.

The management server establishes a database of mobile phones and their users, as well as data on credit (availability of the payment function) of users (called 'blacklist data') as part of these databases. In this case, SMS (Short Messaging Service) or the like can be used as the usage control signal transmitted to the cellular phone.

The mobile phone according to the present invention described above, the contactless IC chip and the RF antenna having the user's unique identification information is provided integrally to the mobile phone can be used as a means of payment other than mobile communication, as well as relatively While using inexpensive contactless IC chips, it is possible to remotely control various functions such as payment through mobile communication of a cellular phone.
