Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a network device initiates a positioning procedure based on existing location requests, then positioning functionality is provided, but the network device cannot accurately determine whether to initiate positioning procedures meeting power consumption requirements
Solution Approach 1:
The patent applies preliminary action by having the terminal device send indication information about its positioning capabilities and power consumption requirements before the positioning procedure is initiated. This allows the network device to pre-determine the appropriate positioning method and configuration that balances accuracy requirements with power consumption constraints, rather than making decisions after the positioning request is received.
Solution Approach 2:
The patent utilizes parameter changes by introducing new information parameters (indication information about terminal characteristics, positioning capabilities, and power consumption requirements) into the positioning request flow. These additional parameters enable the network device to adjust positioning procedure parameters such as measurement frequency, reference signal configuration, and positioning method selection to achieve optimal balance between positioning accuracy and power consumption.
2Reliability
If the network device cannot determine positioning requirements accurately, then positioning procedures cannot be initiated correctly, but adding more information requirements increases signaling overhead
Solution Approach 1:
The patent applies merging by combining the indication information about terminal characteristics and positioning requirements with the existing location request signaling. Rather than creating separate signaling messages, the patent integrates the additional information into the existing positioning request flow, thereby reducing signaling overhead while ensuring the network device receives all necessary information for accurate positioning procedure initiation.
3Productivity
If positioning procedures are initiated without considering terminal characteristics, then positioning can be performed, but power consumption is not optimized for industrial internet of things scenarios
Solution Approach 1:
The patent applies local quality by tailoring the positioning procedure configuration to the specific characteristics of the terminal device and its requirements. Based on the received indication information about terminal capabilities and power consumption constraints, the network device configures positioning parameters locally for each terminal, such as selecting appropriate positioning methods, adjusting measurement frequencies, and configuring reference signal patterns that optimize power efficiency while maintaining positioning efficiency for industrial IoT scenarios.
