A stk menu processing system and its processing method for menus

Abstract

The invention discloses an STK menu processing system and method, comprising: a data receiving module, which receives commands from a mobile phone terminal and converts them into menu update data; an analysis module, which analyzes the menu update data, and obtains update types, menu numbers to be updated and menu The attribute data is sent to the sorting module; the sorting module receives the data received from the sorting module, reads the number of effective menu items and the original sorting linear association data from the menu storage area of ​​the memory, and pairs them according to the update type and the menu sequence number to be updated. The number of valid menu items and linearly related data are processed, and after sorting, they are sent to the data writing and presentation module; the data writing and presentation module updates the data in the menu storage area of ​​the memory according to the received data and organizes them into commands The menu display data for displaying the menu is stored in the cache, and the status word is sent to notify the mobile terminal to read and process the data. The above solution of the present invention makes menu processing flexible and fast.

Description

technical field [0001] The invention relates to the application field of smart cards, in particular to an STK menu processing system and a menu processing method thereof. Background technique [0002] With the popularization of mobile phones and the rapid development of mobile communication technology, mobile Internet and mobile e-commerce, mobile electronic certificates have also been greatly developed. [0003] The continuous introduction of new services and the rapid elimination of old services make it more and more urgent to reorganize and display the menu list on the SIM card after addition and deletion. For example, functions such as leaderboards and service recommendations need to use the limited resources in the SIM card to display a list of services in a specified order, and often need to change the displayed list. At present, some applications on mobile terminals also use list display to intuitively interact with users, transmit information, and have the requireme...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is the use of circular files in the SIM card to add menu list items, but this technology cannot deal with the deletion of menus and the rearrangement and display of menus after deletion.

[0005] Although the traditional linked list structure can meet the problem of menu rearrangement, whether it is menu modification or display, it is necessary to search the entire linked list to find the specified position, and erase and write the FLASH many times during the search and linked list maintenance process, which causes SIM Problems such as shortened service life of the card, complex program structure, and low execution efficiency

Moreover, once an unexpected power failure occurs, the entire linked list may be broken, and the display results are uncontrollable

[0006] And these methods are helpless when the user attempts to create more menu items than the application supports

This implementation method cannot easily replace the oldest menu item, and the user experience is quite bad
