Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If terminal devices report all application layer measurement results to the network side, then the network side can obtain comprehensive QoE data, but the signaling overhead increases and network optimization efficiency decreases
Solution Approach 1:
The patent extracts only the necessary measurement results from the terminal device for reporting to the network side. Specifically, the network side determines which measurement results are needed for network optimization and requests only those specific results from the terminal device, rather than receiving all measurement data. This extraction approach reduces signaling overhead while ensuring the network side obtains the critical QoE information needed for targeted optimization.
2Loss of information
If the network side receives all measurement results from terminal devices, then it can perform comprehensive analysis, but it cannot perform targeted network optimization
Solution Approach 1:
The patent implements local quality by enabling the network side to perform targeted optimization for specific cells based on measurement results from terminal devices receiving broadcast services in those cells. The network side identifies which cells require optimization and requests measurement results specifically from terminal devices in those cells, allowing localized network optimization rather than blanket adjustments across the entire network. This approach improves optimization efficiency by focusing resources on areas that actually need improvement.
3Ease of operation
If terminal devices report measurement results without cell identification, then reporting is simpler, but the network side cannot determine which cell to optimize
Solution Approach 1:
The patent applies preliminary action by having the network side determine and communicate to the terminal device which cell's measurement results are needed before the terminal device performs the measurement and reporting. The network side sends a request indicating the specific cell identity and the measurement parameters needed, so the terminal device can then efficiently report only the relevant measurement result with the corresponding cell identification. This preliminary determination streamlines the reporting process while ensuring the network side receives the correct cell-specific data for optimization.
