(Technology)

The present invention relates to a mobile communication terminal, and more particularly to a mobile communication terminal that can use a contact smart chip in a non-contact in a mobile communication terminal equipped with a contact / contactless smart chip and a contact smart chip.

(Background)

A smart chip (card) 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. It is widely used as a means of record, loyalty management, identity verification (e.g. membership card), electronic money (e.g. transportation card), credit card, electronic bank account.

Smart chips (cards) can be classified in various ways according to their classification criteria, but are classified into contact chips (cards), contactless chips (cards), and contact / contactless chips (cards) according to the way data 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. The power supply for the card is made through RF (Radio Frequency) antenna and refers to the card using the electromagnetic induction method for communication with the interface device. The combined smart chip is a smart chip that supports both contact and non-contact functions. Combi chip is a smart chip configured to share the parts that can be shared contact / contactless in one chip.

As mobile communication terminals (mobile phones) and smart chips are used more and more, and mobile communication terminals are becoming a necessity in everyday life, smart chips are installed in mobile communication terminals as well as traditional plastic cards such as transportation cards. As it came to use.

An example of the application of a smart chip to a mobile communication terminal 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 a mobile phone simply uses a traditional prepaid transportation card. Grafted into.

Another example of a mobile communication terminal to which a smart chip is applied is an electronic passbook function that can be used for inquiry, transfer, withdrawal, and check inquiry through mobile communication to a contact chip by mounting a combination chip including both contact and contactless types. There is a mobile phone equipped with a prepaid transportation card function on a contactless chip.

Another example of a mobile communication terminal using a smart chip is a mobile card in which 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 transportation fee of a traffic card can be paid by credit card credit. There is a telephone.

Combichip, a representative of contact / contactless smart chips widely used in mobile phones, has a contact interface for contact functions, a contactless interface for contactless functions, and an applet for controlling related functions. 6 terminals for contact function (C1: power supply terminal (VCC), C2: initialization input terminal (RST), C3: clock terminal (CLK), C5: ground terminal (GND), C6: program voltage terminal (current (Not used), C7: serial data input / output terminals (I / O)) are connected to the circuit of the cellular phone and act in contact with the CPU of the cellular phone, while the other two terminals (antenna terminals (ANT) of C4 and C8) It is connected to the RF antenna mounted on the mobile phone and works with the external interface without contact.

The present inventor has proposed a 'mobile communication terminal equipped with a plurality of smart chips' of Republic of Korea Patent Application No. 10-2004-0015897 (filed on March 09, 2004).

The mobile communication terminal of the '897 includes a contact / contactless first smart chip, at least a second smart chip having a contact function, an RF antenna for a contactless function of the first smart chip, and a contact chip and a first smart chip. And a contact selection control unit for selectively selecting and activating a contact chip of the two smart chips, and the contact chip of the first smart chip and the contact chip of the second smart chip according to the operation of the contact selection control unit. It is a mobile communication terminal characterized by any one of which is activated so that the contact function is executed.

In addition, the '897 mobile communication terminal further includes an RF selection controller when the second smart chip is a smart chip that provides a contact / contactless function including a non-contact chip. One of the contactless chip and the contactless chip of the second smart chip is activated to enable the activated contactless function.

However, existing mobile communication terminals equipped with two or more smart chips among contact, contactless, and contact / contactless smart chips include contact applets and related data (hereinafter referred to as contact applets) used in contact smart chips. The contact is processed only by contact through the connection of the CPU of the mobile communication terminal, and the contact applet of the contact smart chip has never been used in a contactless manner.

Combi chip, a contact / contactless smart chip that is widely applied to mobile communication terminals, can be used quickly and conveniently because of its non-contact application. Until it grows, there is a limit to its adaptability to various uses. For example, the Combi chip is not suitable for use as a subscriber identity module (eg SIM) for roaming mobile communication terminals that require a lot of storage capacity.

On the other hand, the contact smart chip can be built with a large memory of 128K or more, and has excellent adaptability for various uses, but it is inconvenient to be quick and convenient because the contact applet can be used only as a contact.

Therefore, if the contact applet of the contact smart chip can be used in a contactless manner in a mobile communication terminal equipped with both a contact / contactless smart chip (for example, a combi chip) and a contact smart chip, the contactless smart chip can be enjoyed quickly and conveniently It can be applied for many different purposes.
