Description

Smart card socket for mobile communication terminal {Smart Card Socket for Mobile Telecommunication Terminal}

(Technology)

The present invention relates to a smart card socket for a mobile communication terminal, and more particularly, a composite smart card including an integrated smart card for mobile subscriber identification module and a smart card for payment can be detachably mounted on the mobile communication terminal. It's about sockets.

(Background)

As is widely known, smart cards with ICs equipped with microprocessors, operating systems, security modules, and memory for storage, computing, and security functions can be used for communication, finance, education, administration, and transportation. It is widely used as a means of recording, identifying, and paying information in all fields.

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 inserted into an interface device (reader or reader) that accommodates the contact card. A contactless card is required for an information processing function. The computing element and the memory element are the same as the contact card, but the power supply for driving the IC chip in the card is provided through the coil (RF loop antenna) in the card and uses the electromagnetic induction method for communication with the interface device. The combined card supports both the functions of a contact card and a contactless card, and a representative Combi card is a card configured to share parts shared by a contact / contactless card in one card. to be.

One typical use of smart cards is a subscriber identification module for providing a roaming service of a mobile communication terminal (mobile phone), which is a smart card mounted on a mobile phone.

Such smart card for mobile phone subscriber identity module includes, for example, a subscriber identity module (SIM) card, a universal subscriber identity module (USIM), a user identity module (UIM) card, a removable user identity module (RUIM) card, and the like. Smart card as the same subscriber identification module basically uses a contact smart card to share information with the mobile phone.

In GSM, a European mobile communication system, the above-described SIM card has been applied as a subscriber identification module, which can be referred to as an interface between a cellular phone and a network, in order to cope with a change of a terminal or a change in a carrier. The SIM card contains information about the user, including the phone number. When the power is turned on, the SIM card can exchange information on the SIM card with the network.

The USIM card is a UMTS (Universal Mobile Telecommunications System) capable of transmitting third generation, broadband packet-based text, digitized voice or video, and multimedia data at high speeds of 2 Mbps or higher, regardless of where mobile phones or computer users are in the world. As a smart card to be applied to, it is embedded in the IMT-2000 service terminal and can contain user data along with secret authentication data.

The UIM is a smart card improved to apply the SIM of Europe GSM to the second generation CDMA, RUIM is a removable smart card for applying to the third generation CDMA.

Such smart card as a mobile phone subscriber identification module requires more storage capacity as the use range of the mobile phone increases and the transmission speed of the mobile phone increases. Accordingly, a high memory capacity of 128K bytes or more has recently been applied. There is a trend.

Another use of smart cards is the use of various means of payment, such as electronic money (e.g., transportation cards) or credit cards. As is widely known, a traffic card has a built-in contactless smart card including a loop antenna to store (charge) the amount in advance, and to access the RF reader in a non-contact manner whenever the means of transportation are used. It is a prepaid payment method that allows the transportation fee to be reduced.

However, the conventional RF transportation card is inconvenient to charge the charge in advance by visiting the charging station in advance, so in order to solve this inconvenience, the process of storing the card user's unique identification code (ID) on the card and reading it Cards that can be used for both transportation and credit cards have been developed that allow users to pay for transportation by credit (postpay) by identifying users.

Recently, as mobile payments have increased as the spread of mobile phones has increased, mobile phones have been developed to allow payment of various charges such as traffic charges by mounting a smart card in the mobile phone.

Among the smart card type mobile phones, 6 contact terminals are electrically connected to the mobile phone and 2 terminals are connected to the RF antenna built in the mobile phone, so that the payment information between the RF antenna and the external interface (reader) can be communicated with the mobile phone. There is a combination card mobile phone that allows you to pay post-paid transportation fees. Such a combination card mobile phone can be used for credit settlement through wireless communication with a card payment machine by adding a short range communication module.

The concept of a standardized combination card is shown in FIG. As shown, the combination card 200 is a CPU 210, the input / output unit 220, the main storage unit 230 (RAM, ROM, EEPROM), a contactless and the like to control the entire card in accordance with the system control logic 211 The configuration includes a storage unit 240 (EEPROM), an access matrix 250, a wired I / F and logic 260, an RF loop antenna 270, and the like, which are commonly used.

6 is a terminal arrangement diagram of a standardized combination card. As shown, the terminal side of the combination card 200 has a total of eight terminals of C1 to C8, C1 is a power supply terminal, C2 is an initialization input terminal, C3 is a clock terminal, C4 is an unused spare terminal , C5 is a ground terminal, C6 is a program voltage terminal (not currently used), C7 is a serial data input / output terminal, and C8 is an unused spare terminal.

The combination card 200 can update (record, delete, store, etc.) data through an external interface (reader) by contactless (RF) by connecting an RF loop antenna to the two terminals (preliminary terminals). In addition, by connecting the remaining six terminals to the circuit of the cellular phone, for example, data can be updated through the CPU of the cellular phone. By using the characteristics of the combi card, various payments can be made to the cellular phone equipped with the combi card. You can do it.

However, in general mobile phones to which a smart card is applied, the function of the smart card is divided into only for confirmation of a subscriber of a mobile communication terminal or for payment, and neither of these functions are applied. In the case of the combination card application mobile phone used for the above-mentioned payment, it is possible to consider the combination card itself to function as a mobile communication terminal subscriber identification module through contact between the contact terminal of the combination card and the mobile phone, but has already been developed Combi cards are developed for pure payments, not for subscriber identity modules, so their storage capacity is limited to up to 32K bytes, and it is not yet possible to accommodate both subscriber identity module functions and RF wireless payment functions in combination cards. It is expected to take considerable time.

Under this technical background, the inventors of the last 2002.10.15. Proposed Utility Model Registration No. 20-2002-0030678, 'Mobile communication terminal with smart card' is proposed. This mobile communication terminal has a single contact card with a mobile subscriber identification module and a combination card with a payment function. It is equipped with a removable smart card integrally provided on the board of the mobile communication terminal, so that you can enjoy both the mobile terminal roaming service and payment services, including RF wireless payment.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hybrid smart card built-in mobile communication terminal that combines both a mobile communication terminal subscriber identification module function and a payment function as described above. It is to provide a socket for mounting.
