Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If dual-card dual-standby single-pass terminal uses shared transceiver hardware for networks of the same type, then device complexity is reduced, but simultaneous signal transmission/reception across different operator networks cannot be achieved
Solution Approach 1:
The patent implements dynamic time gap configuration that adapts to different network conditions and operator requirements. The terminal device dynamically adjusts the time gap between switching to different networks based on signal quality, load conditions, and DRX parameters, enabling flexible simultaneous operation on multiple networks while sharing hardware resources.
Solution Approach 2:
The patent utilizes periodic Discontinuous Reception (DRX) cycles to enable the terminal to periodically switch between different operator networks. By configuring appropriate time gaps between DRX cycles of different networks, the terminal can periodically monitor and transmit signals on multiple networks simultaneously without requiring dedicated hardware for each network.
2Reliability
If terminal switches to another network due to poor signal quality or high load, then communication reliability is improved, but manual setting is required affecting user experience
Solution Approach 1:
The patent implements automatic network switching with feedback mechanisms. The terminal continuously monitors signal quality and load conditions of serving networks, and automatically switches to alternative networks when quality deteriorates. The system provides feedback to the user about network switching decisions and maintains user awareness while eliminating manual intervention requirements.
Solution Approach 2:
The terminal device performs self-service network switching by autonomously evaluating network conditions and making switching decisions without user intervention. The device automatically configures time gaps, monitors DRX parameters, and switches networks based on predefined criteria, freeing users from manual network selection while maintaining reliable communication.
3Object-affected harmful factors
If multi-card multi-standby terminal exchanges time-frequency domain information between multiple systems, then self-interference is avoided, but device complexity and information exchange requirements increase
Solution Approach 1:
The patent introduces the time gap configuration as an intermediary mechanism to prevent self-interference. Instead of requiring complex real-time information exchange between multiple network systems, the terminal uses pre-configured time gaps as a mediator to separate transmissions to different networks. This intermediary approach avoids direct interference while simplifying the information exchange requirements.
