(Technology)

The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal equipped with a plurality of smart chips which are equipped with a plurality of smart chips and which can select and use the necessary smart chips so that these smart chips do not collide with each other. It is about.

(Background)

A smart chip is an IC chip equipped with a microprocessor, an operating system, a security module, a memory, etc., and has a storage function, arithmetic function, and security function, and records information and royalties in many fields such as finance, communication, education, administration, and transportation. It is widely used as a means of management, identity verification (eg membership card), electronic money (eg transportation card), credit card, electronic bank account.

Smart chips can be classified in various ways according to their classification criteria, but they can be classified into contact-chip (card), contactless-chip (card), and combined-chip (card) according to the way the data of smart chip is read. .

A contact smart chip refers to a form in which a smart chip is activated by contacting a smart chip contact with a contact of an interface device. A non-contact smart chip is the same as that of a contact type and a memory element required for an information processing function, but to drive a smart chip. It is a type of card that is powered by RF antenna and uses electromagnetic induction method for communication with interface device.Combined smart chip is a smart chip that supports both contact and contactless functions. It is a smart chip configured to share parts where contact / contactless can be shared in one chip.

The combination chip has a terminal standardized as shown in FIG. 2, for example. That is, the combination chip is equipped with a total of eight terminals C1 to C8, where C1 is a power supply terminal (VCC), C2 is an initialization input terminal (RESET), C3 is a clock terminal (CLK), and C4 is not used. Spare terminal (N / C), C5 is the ground terminal (GND), C6 is the program voltage terminal (VPP: not currently used), C7 is the serial data input / output terminal (DATA), C8 is the unused spare terminal (N / C )to be.

Such a combination chip, by connecting the RF antenna to the two preliminary terminals (C4, C8) of the terminals to operate non-contact with the external interface, the remaining six terminals are connected to the circuit of the cellular phone, for example It will work in contact with the CPU.

In the early days, smart chips were widely used as transportation cards, one of prepaid electronic money. This prepaid transportation card is a plastic card type contactless card with a contactless smart chip and an RF antenna. The card is charged at the charging station in advance and charged to the card. It is a smart card of the way that the transportation fee is reduced from the stored amount, there was a inconvenience to visit the charging station to charge the amount.

Since then, the transportation card has been combined with the credit card so that it can be paid as a post-payment by credit like a general merchandise price without additional charges. Such a credit card with a non-contact smart chip and RF antenna is a plastic card of the credit card. It can be said to be combined inside.

As mobile communication terminals (especially mobile phones) and smart chips are used more and more, and mobile communication terminals become necessities of life, smart chips are installed in mobile communication terminals rather than traditional plastic cards such as transportation cards and credit cards. It came to be used to form.

One example of the application of smart chips to mobile communication terminals is a mobile phone equipped with a non-contact smart chip and an RF antenna that can be used to pay for transportation in advance. Such mobile phones simply carry a traditional prepaid transportation card. Incorporating a telephone, the inconvenience of charging is implied.

As another example of a mobile communication terminal to which a smart chip is applied, a combi chip including both contact and non-contact types may be mounted in a mobile phone, and the account inquiry, transfer, withdrawal, and check inquiry may be performed through the mobile communication on the contact-chip. There is a mobile phone equipped with an electronic passbook function and a prepaid transportation card function on a contactless chip. Such a mobile phone has the advantage that you can view the banking business with a mobile phone without visiting the bank. However, since the credit is not granted to the electronic bank account, there is a limit that the payment of the transportation fee is prepaid.

As another example of a mobile communication terminal to which a smart chip is applied, a credit card function is mounted on a contact chip and a traffic card function is mounted on a non-contact chip, so that the fare of a traffic card can be paid by credit card credit. There is a cell phone. In the case of a minor who cannot legally obtain a credit card, such a mobile phone has a limitation in that it cannot use a postpaid transportation card function as well as a credit card function.

In the case of a mobile phone to which the post-paid traffic card function is applied, the traffic card function (RF payment function) of a specific mobile phone is temporarily or permanently stopped or temporarily, such as a charge delay, loss of the mobile phone, or cancellation of the use of the traffic card function. There is a need for resumption (i.e. blacklist management), and the management of such blacklists has traditionally been used to periodically transmit blacklist data to each toll collector (external interface unit).

However, the method of transmitting the blacklist to the toll collector requires a large amount of storage capacity for storing the blacklist data for each toll collector, and there is a limit that the time difference may occur until the new blacklist is updated to the toll collector.

In order to overcome this problem, a technology for managing the blacklist by transmitting a control signal for converting the RF payment function of the blacklisted mobile phone to the usable or restricted state through mobile communication is disclosed in Patent No. 390280 (Smart Chip) Has been proposed as a payment control device and a control method of the mobile communication terminal equipped: registered on June 26, 2003).

1 is a block diagram of a mobile phone as an exemplary mobile communication terminal in accordance with the present invention.

As shown, the mobile communication terminal 1 (for example, a cell phone, described below with reference to a cell phone) in accordance with the present invention includes the basic configuration of a conventional cell phone.

That is, the mobile phone 1 according to the present invention, like a general mobile phone, includes a CPU (eg, Qualcomm chip) for controlling mobile communication functions as a whole, a key input unit for inputting various data and commands, and a mobile phone. Communication unit equipped with a monitor for displaying various information on the use of the phone, a memory for storing the program and the various data input and output of the mobile phone, and an antenna and duplexer for mobile communication with the base station through the antenna Basically, the audio unit includes a speaker and a microphone for a call, and a power supply unit for supplying power. In the accompanying drawings, the CPU 2 and the user can control various operations through the CPU 2. Other components except for the user interface 3 including the input unit and the like have been omitted.

Accordingly, the mobile phone 1 of the present invention inputs predetermined data and commands using the user interface 3 including a key input unit, monitors related information through a monitor, and stores and deletes data necessary for the memory. The mobile communication is executed through the communication unit, and all these operations are controlled by the CPU 2.

According to a feature of the present invention, the cellular phone 1 of the present invention basically includes a first smart chip 10, a second smart chip 20, an RF antenna 30, and a contact selection controller 40. .

The first smart chip 10 is a smart chip including both contact and contactless functions, like a conventional combi chip, and may be detachably mounted on the mobile phone 1, but is preferably integrally mounted on the mobile phone. .

That is, the first smart chip 10 has a contact-part 11 and a non-contact part 12, and is known in the well-known surface mount technology (SMT), for example, TSSOP, BALL, PLCC, etc. It is preferably mounted integrally to the circuit of the mobile phone 1, for this purpose, the first smart chip 10 is preferably packaged as a surface mounted device (SMD).

As a result, in the first smart chip 10, which is standardized as a combination chip, the two antenna terminals C4 and C8 of the contactless part 12 are connected to the RF antenna 30 while the remaining six terminals C1 are connected. , C2, C3, C5, C6, and C7 are electrically connected to the circuit of the mobile communication terminal 1.

Preferably, the contact-part 11 of the first smart chip 10 includes a loyalty management function for managing a user's performance and the like, and a membership card function used as an identification means for access control. A non-monetary function, which is not directly related to the financial function, is mounted, and the contactless part 12 is connected to the RF antenna 30 to realize a prepaid fare payment function such as a prepaid traffic card function.

The second smart chip 20 is a combination chip having both the contact-part 21 and the non-contact part 22 like the first smart chip 10, but only the contact-part 21 is used. It is also possible to apply a smart chip provided.

In addition, although the second smart chip 20 is not excluded from being mounted on the mobile phone 1 like the first smart chip 10, the second smart chip 20 is preferably electrically connected to the mobile phone 1 by being detachably mounted. When the second smart chip 20 is a combination chip including the contactless part 22, the terminals C4 and C8 of the contactless part 22 are connected to the RF antenna 30.

Preferably, the contact type part 21 of the second smart chip 20 is equipped with various financial functions including a credit card function, an electronic bank account, and the like. That is, the second smart chip 20 may be referred to as a smart chip equipped with a financial function such as a credit card or an electronic bankbook provided to each customer by financial institutions.

As the financial function is mounted on the contact-part 21 and the second smart chip 20 can be detachably mounted on the mobile phone 1, the user wants to use among the smart chips issued by each financial institution. Selecting a smart chip (that is, the second smart chip 20) to be mounted on the smart chip mounting socket provided in the mobile phone 1 can be used.

The contactless part 22 of the second smart chip 20 is connected to the RF antenna 30 to realize a postpaid fare payment function such as a postpaid transportation card function.

When the contact-part 21 is equipped with an electronic bankbook function rather than a credit card function, the non-contact part 22 may be equipped with only a prepaid billing function, not a post-paid payment. In this case, the non-contact part 22 Since the prepaid fee payment function of the first smart chip 10 is unnecessary overlapping with the prepaid fee payment function of the non-contact part 12 of the first smart chip 10, the second smart chip 20 only needs to have the contact-part 21. .

The RF antenna 30 generates induction electromotive force upon access to an RF reader 5 such as a traffic fare collector, thereby causing data related to payment of a fare such as a traffic fare between the smart chip 10, 20 and the RF reader 5. It is a conventional RF antenna to allow the transmission of.

When the second smart chip 20 includes only the contact-part 21, the RF antenna 30 is connected only to the non-contact parts 12: C4 and C8 of the first smart chip 10, and the second smart chip 20. If the chip 20 also has a contactless part 22, the RF antenna 30 is also connected to the contactless parts 22 (C4, C8) of the second smart chip 20.

Preferably, the RF antenna 30 is embedded in a position, for example, the battery 4, which is capable of receiving the minimum electromagnetic wave blocking action applied to the cellular phone 1.

Since the mobile communication terminal 1 according to the present invention basically has two smart chips 10 and 20 mounted at the same time, only a smart chip desired by a user in using these smart chips 10 and 20 is used. It needs to be activated and controlled to prevent mutual collisions.

In order to selectively activate only a desired chip among the two contact-parts 11 and 21, the mobile communication terminal 1 of the present invention is provided with a contact selection control unit 40. The contact selection control unit 40 according to the order determined to the CPU 2 or as the user commands through the user interface 3, the contact-part 11 and the second of the first smart chip 10 Only one of the contact-parts 21 of the smart chip 20 is activated to prevent mutual collisions in its operation.

In the illustrated embodiment, by applying a circuit of a multiplexer 41 (MUX: multiplexer) between the contact-part 11 and the contact-part 21, instructions via the user interface 3 are transferred to the CPU 2. Is delivered to the multiplexer 41 so that only the user-selected contact-part (eg, 11) is selectively activated and the other chip (eg, 21) is deactivated. The configuration of the circuitry for selectively activating the contact-part 11 and the contact-part 21 may be used by adapting well-known conventional circuit techniques in accordance with the present invention.

Therefore, when the user instructs the contact-part 11 to be activated through the user interface 3 or receives a signal confirming a recognition code from an external interface device such as a membership card reader, only the contact-part 11 is received. Activated and the contact-part 21 remains inactive so that the non-financial functions (e.g., royalty management or identity functions) illustrated above can be performed, but the financial functions (e.g. credit card functions or electronic banking functions) are suspended. It will remain

On the contrary, if the user instructs the contact-part 21 to be activated through the user interface 3, only the contact-part 21 is activated and the contact-part 11 is in an inactive state. The electronic bankbook function can be executed, but the identification function and the like remain suspended.

Preferably, when the mobile phone is initially powered or the use of the contact-part 21 is terminated, the credit-part 21 is deactivated and the contact-part 11 is activated to thereby activate the credit card. Financial functions such as functions can be activated only at the moment desired by the user and otherwise deactivated.

In the case where the non-contact part 22 is included in the second smart chip 20, since the two non-contact parts 12 and 22 are included, it is necessary to control the user to activate only the desired chip. have. To this end, the mobile communication terminal 1 of the present invention may further include an RF selection control unit 50.

The RF selection controller 50 may be configured to perform the contactless part 12 of the first smart chip 10 and the contactless part 22 of the second smart chip 20 as the user commands through the user interface 3. Activates only one so that they can be used selectively without conflict.

In the illustrated embodiment, by applying the multiplexer 51 between the contactless-part 12 and the contactless-part 22, instructions via the user interface 3 are directed to the multiplexer 51 via the CPU 2. It is delivered to be activated so that only the contactless part (eg, 12) selected by the user is activated and the other chip (eg, 22) is deactivated.

Therefore, when the user wants to use the prepaid transportation card function, the user interface (3) instructs the contactless part 12 to be activated so that only the contactless part 12 is activated so that the user can pay the transportation fee in advance. This option is appropriate if you are a minor and cannot receive a credit card.

On the contrary, if the user instructs the contactless part 22 to be activated through the user interface 3, only the contactless part 22 is activated, so that the transportation fee can be paid postpaid by a credit card. It is suitable for the case where the credit card function is mounted on the contact-part 21 of the second smart chip 20.

According to the operation of the first smart chip 10, the second smart chip 20, the RF antenna 30, the contact selection controller 40 and the RF selection controller 50 described above, the user may use the smart chip 10. It is possible to use both non-financial functions such as royalty management and identity verification function and financial functions such as credit card or electronic bank account without any conflict of 20). Depending on your status, you can choose to use it in advance or after payment.

The mobile communication terminal 1 of the present invention may further include an RF payment control unit 60 as exemplified through Korean Patent No. 390280. The RF payment control unit 60 controls the functions of the contactless parts 12 and 22 to be in an available state or in a restricted state, and such control is performed by the CPU 2 by the control signal transmitted through the mobile communication. By controlling 60.

Therefore, black list management such as the charge delay, the loss of the mobile phone, the cancellation of the use of the transportation card function, or the like must be stopped or resumed temporarily or permanently. Through the function, it can be performed in real time using the CPU of the mobile communication terminal.

In the above description of the present invention, an example in which a mobile telephone is applied as a mobile communication terminal has been mainly described. Naturally, the present invention can be applied to other mobile communication terminals including a PDA having a function as it is.
