Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data compression is performed to improve transmission efficiency, then transmission resources are utilized more efficiently, but data compression failures may occur causing data loss
Solution Approach 1:
The patent applies preliminary action by performing integrity verification before data compression and preparing compression failure handling procedures in advance. The receiving end verifies data integrity prior to decompression, and both ends prepare fallback mechanisms (such as discarding compressed data and requesting retransmission) to handle potential compression failures, thus preventing data loss while maintaining efficient transmission.
2Reliability
If integrity verification is performed to enhance security, then data integrity is protected, but verification failures may occur causing transmission delays
Solution Approach 1:
The patent implements feedback mechanisms where the receiving end sends verification results back to the transmitting end. When integrity verification fails, the receiving end notifies the transmitting end, which then requests retransmission of the compromised data. This feedback loop ensures data integrity while enabling efficient error handling through targeted retransmission rather than complete data rejection.
Solution Approach 2:
The patent performs integrity verification in advance before data compression and preparation. By verifying data integrity beforehand and preparing verification results for immediate use during decompression, the system minimizes verification time while ensuring security. The verification process is integrated into the data flow rather than adding separate verification steps.
3Ease of operation
If handover procedures are implemented to support mobility, then seamless connection is achieved, but handover failures may occur causing service interruption
Solution Approach 1:
The patent applies preliminary action in handover by preparing handover parameters and configuration information before the actual handover occurs. The network pre-configures resource allocation, bearer settings, and security parameters for the target cell, enabling the terminal to execute handover quickly and reliably without service interruption. This preparation phase ensures both smoothness and reliability of the handover process.
4Productivity
If data compression is applied to improve uplink transmission, then transmission resources are saved, but decompression failures may occur at the receiving end
Solution Approach 1:
The patent performs integrity verification before data compression at the transmitting end and prepares verification results for immediate use at the receiving end. This preliminary verification ensures that only valid, uncorrupted data is compressed and transmitted, preventing decompression failures. The receiving end uses the pre-prepared verification results to quickly validate decompressed data, ensuring both efficiency and reliability.
