Description

SMART CARD ADAPTER FOR MOBILE TERMINAL {SMART CARD ADAPTER FOR MOBILE COMMUNICATION TERMINAL}

The present invention relates to a mobile communication terminal device, and more particularly to a smart card adapter of a mobile communication terminal using a smart card.

Smart cards are equipped with integrated circuit (IC) chips with microprocessors, security modules, memory, and the like, and are widely used as a means of payment for recording various types of information, verifying identity, electronic money, credit cards, or electronic accounts. Such smart cards may be classified into contact cards, contactless cards, and contact / contactless cards (eg, combination cards), depending on how the IC chip's data is read.

Recently, smart cards are generally installed in mobile communication terminals. Smart cards mounted in mobile communication terminals are functionally integrating smart cards and mobile communication terminals by mounting them in a built-in or removable form, rather than in the form of traditional plastic cards. The integration of the smart card and the mobile communication terminal is also applied to the case of using the smart card as a subscriber identification module to provide roaming services of the mobile communication terminal.

Smart cards as subscriber identification modules include a subscriber identification module (SIM) card, a universal subscriber identification module (USIM) card, a user identification module (UIM) card, and the like. In 1982, the European Postal and Communications Management Council (CEPT) introduced a SIM card of about 4 kilobytes of EEPROM for the purpose of user authentication, creating a single standard for the Global System for Mobile Telecommunication (GSM). Based on the SIM card standard, the standardized UIM including all SIM modules for roaming with GSM. Asynchronous third generation mobile communication (WCDMA) terminals are equipped with a USIM card.

Currently, in Europe, all GSM-type mobile phones must have a SIM card built in to make the mobile phone work. Recently, the third generation mobile communication service in Korea also requires the use of USIM cards. USIM is a step up from SIM, and is a chip-sized chip that is essentially inserted into asynchronous third-generation mobile communication (WCDMA) terminals. USIM combines the role of a SIM to authenticate subscribers and the functionality of a Universal IC Card (UICC) that can carry functions such as a transportation card or credit card. The universal IC card ensures the integrity and security of all personal information data through the security support of various multiple applications. The USIM consists of a small CPU and memory. The CPU identifies the user with an encryption / decryption function, and the memory is used as a storage space for additional services. The memory can contain functions such as credit card, transportation card, membership card, etc. In particular, the OTA (Over The Air) technology allows the service to be installed wirelessly without a separate chip if banking or card service approval is required. .

Such a smart card, such as a SIM card or USIM card may be semi-permanently mounted in the mobile communication terminal, but in recent years is mainly configured to be removable. When a smart card is applied to a mobile terminal detachably, conventionally, when a battery is removed from a mobile terminal, a smart card socket is provided at the rear of the mobile terminal, or a smart card socket is provided at the rear of the battery. When the smart card is mounted and the battery is mounted in the mobile communication terminal, the smart card is mounted in the mobile communication terminal. Alternatively, the smart card socket is provided at one side of the mobile communication terminal, and the smart card is used by sliding the smart card.

All of these methods have a problem in that the smart card socket is located inside the mobile communication terminal and the space for inserting the smart card must exist, thereby increasing the volume of the mobile communication terminal. In addition, when the smart card socket is located in the battery compartment or the battery itself, there is a problem that the power must be turned off by removing the battery every time the smart card is replaced. This has the disadvantage that it takes unnecessary time other than the time required for smart card recognition because the mobile communication terminal must be rebooted every time the smart card is replaced.

In addition, in manufacturing a mobile communication terminal for export to a country where different smart cards are used, the design cost of the terminal increases and production is increased by changing the internal circuit arrangement of the mobile communication terminal and the type of smart card socket for each type of smart card. There is a problem that the unit price increases. In addition, as global roaming is activated, a mobile communication terminal supporting all different mobile communication standards requires different types of smart card sockets to be equipped with different smart cards. There is a problem that increases.

The present invention is to solve the above-mentioned problems, it is an object to miniaturize a mobile communication terminal using a smart card.
