Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal device uses the currently camped RAN as auxiliary RAN for sensing, then the system complexity is reduced, but the sensing accuracy and reliability deteriorate when the camped RAN is not suitable for specific sensing tasks
Solution Approach 1:
The patent introduces a network device as an intermediary that manages and coordinates multiple auxiliary RANs for the terminal device. This intermediary selects and configures appropriate auxiliary RANs based on sensing task requirements, thereby improving sensing accuracy without significantly increasing terminal device complexity. The network device acts as a mediator between the terminal device and multiple RANs, optimizing the selection process.
Solution Approach 2:
The terminal device is configured to work with multiple auxiliary RANs simultaneously, enabling it to perform different sensing tasks with different RANs based on specific requirements. This multi-functionality approach allows the system to adapt to various sensing scenarios (respiratory monitoring, environmental imaging, weather monitoring) by selecting the most suitable RAN for each task, thereby improving overall sensing accuracy.
2Ease of operation
If the terminal device uses only the currently camped RAN for sensing, then the ease of operation is improved, but the adaptability to different sensing task requirements deteriorates
Solution Approach 1:
The network device performs preliminary actions by pre-configuring and selecting appropriate auxiliary RANs for the terminal device based on anticipated sensing task requirements. This preliminary configuration allows the terminal device to quickly adapt to different sensing tasks without complex real-time decision-making, maintaining ease of operation while improving adaptability. The network device prepares the RAN configuration in advance before the actual sensing task begins.
3Reliability
If multiple auxiliary RANs are configured for the terminal device, then the sensing reliability is improved, but the device complexity increases
Solution Approach 1:
The network device serves as an intermediary that manages the complexity of coordinating multiple auxiliary RANs. It handles the selection, configuration, and coordination of multiple RANs, thereby improving sensing reliability through diverse RAN options while preventing the terminal device from bearing the full burden of complexity. The intermediary abstracts the complexity away from the terminal device.
