UICC Application Metadata Extraction for Unified Mobile Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile equipment (ME) UICC application access is cumbersome due to dynamic menu generation and lack of icon support, leading to slow navigation and user unfriendliness, especially on low-performance devices, and the Smart Card Web Server (SCWS) protocol stack and interface limitations prevent efficient web-like interface deployment.
Innovation Solution
A new protocol that allows ME to retrieve UICC application metadata for unified icon-based access, enabling direct launch of UICC applications from a unified user interface, similar to ME applications, by defining metadata, a new Elementary File, and an Envelope command for seamless interaction between ME and UICC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UICC applications are accessed via the UICC services menu with dynamic menu generation, then security and application functionality are maintained, but navigation time and user interaction steps increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-generating and caching the UICC services menu structure and application information on the mobile equipment before user access. Instead of dynamically generating menus during user interaction, the system prepares the menu structure in advance, storing it locally so that users can access UICC applications directly without experiencing the time-consuming dynamic menu generation process during actual use.
2Ease of operation
If icons and pictures are added to UICC menu items to improve user interface, then user experience is enhanced, but data transmission volume from UICC to ME increases
Solution Approach 1:
The patent extracts the icon and picture data from the UICC and stores them separately in the mobile equipment's memory. Instead of transmitting all icon data from UICC to ME during menu generation, the system extracts and caches these graphical elements locally on the ME, reducing the data transmission burden while maintaining high-quality visual user interface elements for UICC application access.
3Adaptability or versatility
If SCWS protocol stack with TCP/IP support is implemented in UICC to enable web-like interface, then user interface modernization is achieved, but device complexity and implementation requirements increase
Solution Approach 1:
The patent introduces an intermediary approach by implementing a simplified protocol layer on the mobile equipment that mediates between the UICC and the web-like user interface. Instead of requiring full TCP/IP stack implementation within the UICC, the system uses an intermediate software layer on the ME that handles web protocol processing, allowing the UICC to maintain its simpler structure while still enabling modern web-based application access patterns.

AI summary
A mobile device is provided having a smart card. The smart card is programmed with UICC applications metadata that is provided to the mobile device during a power-up or reset routine. The mobile device uses the UICC applications metadata to generate a user interface that allows a user to launch directly an application on the smart card. Icons for the UICC applications can be displayed together with icons for applications residing on the mobile device. In this way, the user selection of UICC resident applications is facilitated and can be made transparent to the user.
