Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement results from different communication systems are transmitted and processed to determine network device changes, then the accuracy of network transition determination is improved, but the communication overhead and processing complexity increase
Solution Approach 1:
The patent segments the measurement results into two distinct types: first measurement results from the first communication system and second measurement results from the second communication system. This segmentation allows the network device to process and evaluate each type of measurement result separately, managing complexity while maintaining comprehensive accuracy for network transition determination.
Solution Approach 2:
The network device performs multiple functions using the same measurement result transmission mechanism: it evaluates both first measurement results for first network device changes and second measurement results for second network device changes. This multi-functionality improves determination accuracy without proportionally increasing processing complexity.
2Reliability
If measurement results are transmitted between network devices to enable accurate network transition determination, then the reliability of network switching is improved, but the communication overhead increases
Solution Approach 1:
The patent extracts only the essential measurement results needed for network transition determination from the complex dual-connectivity scenario. By transmitting specifically the first and second measurement results without unnecessary additional information, the patent maintains high reliability of network switching while minimizing communication overhead.
Solution Approach 2:
The network device performs preliminary evaluation of measurement results before triggering network device changes. This preliminary action ensures that only necessary switching operations are executed based on accurate measurement evaluation, improving reliability while avoiding unnecessary communication overhead from redundant switching operations.
