Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device switches between connected and inactive states, then the terminal device can flexibly adapt to different transmission scenarios, but the data compression continuity cannot be ensured
Solution Approach 1:
The patent applies local quality by defining a specific target data compression area within the inactive state where compression rules locally apply. The terminal device determines whether it is located in the target data compression area and applies compression only in that specific region, allowing state switching flexibility while ensuring compression continuity when conditions are met.
Solution Approach 2:
The patent implements dynamics by making the data compression behavior adaptive rather than static. The terminal device dynamically adjusts compression execution based on real-time conditions: whether it is in the inactive state, located in the target data compression area, and the data volume threshold. This dynamic approach resolves the contradiction between state flexibility and compression continuity.
2Productivity
If data compression is always executed during SDT, then data transmission efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent applies partial action by executing data compression only under specific conditions rather than always. The terminal device checks whether it is in the target data compression area and whether the data volume exceeds a threshold before executing compression. This partial execution approach improves transmission efficiency for relevant data while avoiding unnecessary complexity for other scenarios.
3Manufacturing precision
If the terminal device determines location in target data compression area, then compression accuracy is improved, but the measurement precision requirement increases
Solution Approach 1:
The patent uses the target data compression area configuration as an intermediary that simplifies location determination. Instead of requiring precise real-time location measurement, the network side device pre-configures the target data compression area, and the terminal device determines location by checking whether it is in the configured area, reducing measurement precision requirements while maintaining compression accuracy.

AI summary
A data compression method and apparatus. The method comprises: a terminal device receiving small data transmission (SDT) configuration information from a network side device, the SDT configuration information being used for instructing the terminal device to perform SDT, determining a target data compression area, and in response to the terminal device being located in the target data compression area, executing the data compression while performing SDT. In this way, the terminal device can perform data compression in the target data compression area while performing SDT, thereby improving the performance of data transmission.
