Visual development system and visual development method of Java-card application toolkit (CAT)

Abstract

The invention discloses a visual development system of a Java-card application toolkit (CAT). The visual development system comprises a visual flow editing module, a terminal simulation module, an execution simulation module and an application publishing module, wherein the visual flow editing module provides an editing interface which comprises a component corresponding to a proactive command of the Java-CAT and generates a communication smart card executable file; the terminal simulation module provides an environment for operation of a mobile phone terminal; the execution simulation module provides a simulation communication smart card multi-application platform and carries out simulation execution on the Java-CAT; the application publishing module is used for publishing a communication smart card executable downloaded file which is generated by the visual flow editing module; and the terminal simulation module displays an execution result of the execution simulation module on the Java-CAT in a graphical form. The invention also provides a method for development by using the visual development system of the Java-CAT. By the system and the method provided by the invention, the component and attributes of the CAT are displayed on a graphical interface, difficulty in development of the CAT is reduced, a development period is shortened, and development efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the Java-CAT of the communication smart card, in particular to a development system and a development method of the Java-CAT of the communication smart card. 【Background technique】 [0002] CAT is the English abbreviation of CardApplication Toolkit, that is, user identification application development tool. CAT contains a set of instructions for the interaction between the mobile phone and the SIM (USIM) card, so that the SIM (USIM) card can run the small application program in the card, so as to achieve the purpose of value-added services. CAT provides users with a text menu interface, which allows users to realize information retrieval and even transactions through simple button operations. [0003] Java Card technology is a technology that combines a subset of the Java programming language with an optimized runtime environment. This optimization is specific to embedded devices with small storage capacity, such as communi...

AI Technical Summary

Problems solved by technology

Because the Java compiler is relatively professional, it is difficult to be proficient in development. Therefore, Java-CAT is mostly developed by professional developers and then preset in the SIM (USIM) card or published in the SIM (USIM) application download server. Thus limiting the promotion of SIM (USIM) card secondary development capabilities

[0007] On the other hand, due to the use of Java language to describe the business logic of the CAT program, it is difficult to express the logic flow relationship intuitively, which leads to the problems of difficult development of the CAT program, long development cycle, and high application maintenance cost.
