Smart Card Widget UI Data Update via Terminal Autonomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an efficient method for managing download setup information for widget UI programs on smart cards, leading to increased power consumption due to periodic communication between user terminals and smart cards for updating widget UI data.
Innovation Solution
An interworking system between user terminals and smart cards, where the smart card provides widget download setup information including update data, access URL, and access frequency to a program provision server, allowing the user terminal to periodically download and update widget UI data without additional requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user terminal periodically communicates with the smart card to update widget UI data, then the widget UI data can be kept updated, but power consumption increases
Solution Approach 1:
The system performs preliminary actions by having the user terminal obtain widget download setup information (including download URLs and schedules) from the smart card in advance. The terminal then autonomously downloads and updates widget UI data according to predetermined schedules without requiring frequent active communication with the smart card, thereby reducing power consumption while maintaining data freshness
Solution Approach 2:
The user terminal is empowered to autonomously manage widget UI data updates by itself. It obtains necessary information from the smart card once, then independently schedules and executes downloads based on setup information, eliminating the need for continuous smart card involvement and reducing communication-related power consumption
2Reliability
If the user terminal frequently downloads widget UI data, then the data can be kept updated, but communication overhead increases
Solution Approach 1:
The system implements periodic action by establishing predetermined download schedules for widget UI data. The user terminal downloads data at specific intervals or times based on setup information from the smart card, rather than continuously or on-demand, thereby balancing data freshness with reduced communication overhead and time consumption

AI summary
Disclosed are an interworking system between a user terminal and a smart card for executing a widget and a method thereof. The interworking system is configured to enable the user terminal to manage the download setup information for a widget UI (user interface) program installed in the smart card. The user terminal is able to download widget UI data to be updated from a program provision server based on the download setup information even if there is no additional request from the smart card. Therefore, the system is able to prevent periodic communication between the user terminal and the smart card when updating the widget UI program.
