Method of data exchanging between software and user identity identification card on mobile phone

Abstract

The invention relates to a method of data exchanging between software and a user identity identification card on a mobile phone. The method is characterized in that a feature code is added in a phone number address book or a message recorder stored in the user identity identification card, the application software and the user identity identification card on the mobile phone can both judge whether further filter process and corresponding analysis and process need to be carried out to data in the identified phone number address book or the message recorder through identification of the feature code, and therefore the application software on the mobile phone can exchange data with the user identity identification card. According to the method of data exchanging between the software and the user identity identification card on the mobile phone, an interactive channel of the phone number address book and the message recorder between the user identity identification card and a mobile phone operating system is utilized, the feature code identification and filter method is combined, and therefore the application software on the mobile phone can exchange data with the user identity identification card, and better man-machine interface and functions and more safe application development are provided.

Description

technical field [0001] The invention relates to the technical field of safe data exchange with a user identification card on a mobile phone, in particular to a method for exchanging data between a mobile phone and a user identification card through software. The subscriber identity card is a SIM (Subscriber Identity Module, also called a smart card) card or a USIM (Universal Subscriber Identity Module, called an upgrade SIM) card. Background technique [0002] The mobile phone is already an indispensable tool in modern life. If it is simply described, the mobile phone is composed of three parts: [0003] The first block is mobile phone hardware and mobile phone operating system. [0004] The second largest block is various application software running on the mobile phone operating system, which is referred to as application software on the mobile phone for short in this application. [0005] The third block is the user identification card used for authentication with the m...

Problems solved by technology

These operations can only be completed on an independent interface. All application processes are controlled and completed by the user identification card, while the mobile phone is just a passive interpreter and executor, unable to control any application process, and cannot Works with apps on other phones

Although such STK (UTK) applications have a man-machine dialogue input and output interface, they are all limited to the original function interface of text input and output; although they have a certain processing capacity, all processing operations are handed over to a computer with a very high computing capacity. Weak and limited user identification card can not produce a better human-machine dialogue interface and more powerful functions like the application software on ordinary mobile phones, and it is far from satisfying the current various hot applications.
