UICC Protocol Switch for Power Conservation

The patent implements dynamic switching between USB mode and ISO mode based on real-time conditions. The system monitors battery power levels, enumeration status, and user preferences to automatically select the most appropriate transmission protocol, making the system adaptable rather than static. This resolves the contradiction by allowing the device to use USB mode when high performance is needed and ISO mode when power conservation is prioritized.

The patent changes the operational parameter (transmission protocol mode) based on different conditions. By monitoring battery power thresholds, enumeration success, and user-defined preferences, the system switches between two distinct protocol parameters (USB and ISO modes), optimizing the balance between data transmission capability and power consumption according to the current operational context.

The system dynamically selects between ISO mode and USB mode based on real-time conditions. When power conservation is the priority (low battery, successful enumeration in ISO mode), the system operates in ISO mode. When higher data transmission capability is needed and conditions permit, it switches to USB mode, making the performance characteristic adjustable rather than fixed.

The patent makes the UICC interface universal by supporting both USB mode and ISO mode operations. The system can function effectively in either protocol mode depending on conditions, allowing it to serve multiple operational requirements. This multi-functionality resolves the contradiction by enabling the same hardware interface to deliver different performance characteristics as needed.

The patent implements self-service through automatic fallback functionality. The system monitors its own operational status (enumeration success, battery power levels) and autonomously switches between USB mode and ISO mode without requiring user intervention. This self-managing approach extends battery life through intelligent protocol selection while keeping the user interface simple, resolving the contradiction between extended battery life and device complexity.

The system uses feedback mechanisms to monitor enumeration status, battery power levels, and mode operation effectiveness. Based on this feedback, the system automatically adjusts its operational mode, switching from USB to ISO mode when appropriate conditions are detected. This feedback-driven control enables battery life extension through intelligent switching while maintaining manageable complexity through rule-based decision logic.

The system performs self-service by automatically managing protocol mode selection based on monitored conditions. The fallback mechanism operates autonomously, detecting enumeration failures or low battery states and switching modes without user intervention. This self-managing approach provides high adaptability while maintaining ease of operation, as users do not need to manually manage the complexity of mode switching.

The patent implements preliminary action by establishing user preferences and power thresholds in advance. During setup, users can define their preferred operational modes and power level thresholds. The system then uses these pre-configured parameters to automatically make switching decisions, providing adaptability through multiple mode options while maintaining ease of operation through simple advance configuration rather than complex real-time user decisions.
