Designing And Realizing A Data Management Method Based On High Capacity Phone Book Of SIM

With the great development of the CMOS chip, Smart Card which Plays the role as a new Application Platform is widely use in many fields. Smart Card is a synthesis of many kinds of technologies, such as micro-electronics, computer, information security, and so on. As a kind of high technology Product, Smart Card can widely improve the modernization level of people's life and work, So it becomes one of the development level symbols of a country.The SIM card which develops fast, is one of the most popular fields of Smart Card, The design and development of the SIM card in GSM system not only follow GSM criterion, but also have good expansibility to satisfy the market requirement. At the beginning of telecommunication development, the main operation is voice operation, and most of the resource is used to deal with the voice communication among the users in order to satisfy the request of the call. Subsequently, the customers have brought new request to telecommunication, and the SIM storage capability and more various requests of the customers, So it gives birth to the Phase 2 SIM card, which uses the huge SIM data storage technology to help the telecom corporation to develop different kinds of Service which makes the SIM Application various.This paper gives us the Designing and Realizing A Data Management Method Based On High Capacity Phone Book of SIM, and the good result of using this theory has proved its worth.
