Automatic SIM Switching for Application-Based Carrier Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in selecting the appropriate SIM for communication due to the need to manually understand and switch between multiple SIMs or eSIMs based on factors like fees, communication speed, and service quality for different applications, making the process cumbersome and often leading to suboptimal choices.
Innovation Solution
A communication apparatus that includes a processor and memory to automatically recommend a suitable SIM for an application based on user contracts with multiple carriers, using an application server to manage SIMs and provide notifications for seamless switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually selects a SIM for communication, then the user can control which communication line to use, but the process becomes cumbersome and inconvenient
Solution Approach 1:
The communication terminal automatically determines and switches between SIMs based on application information and contract data stored in the terminal. The system performs self-service by autonomously selecting the appropriate SIM for each application without requiring user intervention, thereby simplifying the operation while managing multiple communication lines
Solution Approach 2:
The terminal stores contract information for multiple communication lines in advance, including application-specific data and SIM selection criteria. This preliminary preparation enables the terminal to quickly and automatically determine the appropriate SIM when an application is launched, eliminating the need for manual user decision-making
2Ease of operation
If the terminal automatically determines SIM selection, then user convenience is improved, but the terminal needs to store and process contract information
Solution Approach 1:
The terminal extracts only the necessary contract information and SIM selection criteria from the complete contract data set. By storing only the essential elements needed for automatic SIM determination (application information, SIM selection rules, and carrier data), the terminal reduces the quantity of stored information while maintaining the capability for automatic SIM selection
