Problems solved by technology

However, since important data such as the user's phone number, key and encryption algorithm are stored in the smart card, if the network needs to be changed, the user must replace the smart card in the terminal device.
Due to the different types of PIM/SIM/UIM smart cards, the user data is not the same, so you will encounter the problem of incompatibility of data in different types of smart cards
Data such as phone bo

Abstract

A mobile terminal supporting intelligent cards in different type consists of intelligent card judging unit for judging out type of intelligent card inserted in intelligent card slot by utilizing exclusive file of detecting intelligent card, data fetching unit for fetching out data in intelligent card according to judging out type and data storage unit for storing data fetched out by data fetching unit. It features that three types of intelligent card as PIM / SIM / UIM can be operated on one intelligent card slot of one mobile terminal.

Description

technical field [0001] The invention relates to mobile terminal equipment supporting different types of smart cards. Background technique [0002] Currently, there are three types of communication networks in China, namely PHS, GSM, and CDMA. Correspondingly, the mobile device terminals supporting these three types of networks respectively support three types of smart cards, PHS PIM card, GSM SIM card, and CDMA UIM card. [0003] With the continuous development of China's mobile communication industry, the number of users under the three networks has been increasing, and the number of mobile users has become saturated at present. On the one hand, mobile operators are constantly developing new network customers, and on the other hand, they hope to transfer users from other networks to their own networks. However, since important data such as the user's phone number, key and encryption algorithm are all stored in the smart card, if the network needs to be changed, the user m...
