Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM technology in wireless communication systems faces performance issues due to shared radio and baseband components across multiple SIMs, leading to inefficiencies and disruptions in network connections.
Innovation Solution
A method and apparatus that allow a user equipment (UE) to communicate with multiple base stations using different SIMs, where the UE transmits request signals to manage connections and receive configuration messages to suspend or release connections based on specific indicators, enabling efficient switching and management of SIM usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multi-SIM technology is implemented with shared radio and baseband components, then cost efficiency is improved, but connection performance and reliability deteriorate
Solution Approach 1:
The patent segments the connection management process by introducing separate request signal transmission and configuration message reception mechanisms for each SIM card. This allows independent control of each SIM's connection state despite sharing physical components, thereby maintaining reliability while preserving cost efficiency.
Solution Approach 2:
The system dynamically switches between different connection modes (connected mode and suspension mode) based on real-time needs. The UE can transition between these modes for different SIMs independently, allowing flexible adaptation to varying network conditions while maintaining stable connections when needed.
2Adaptability or versatility
If connection switching between multiple SIMs is enabled, then adaptability is improved, but connection stability deteriorates
Solution Approach 1:
The system performs preliminary actions by establishing dedicated request signal transmission procedures before actual connection switching occurs. The UE proactively notifies the network of its multi-SIM status and connection state changes, allowing the network to prepare appropriate configuration messages in advance, thereby maintaining stability during switching operations.
Solution Approach 2:
The patent implements feedback mechanisms where the network responds to UE requests with configuration messages that specify suspension or release actions. This closed-loop feedback ensures that connection changes are coordinated and controlled, maintaining stability while enabling adaptability across different network conditions.
