Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static RRC configuration is used for transmission entity processing, then device complexity is reduced and ease of operation is improved, but data loss occurs and reliability deteriorates during dynamic cell changes
Solution Approach 1:
The patent introduces dynamic processing for transmission entities by differentiating between mobility procedures based on purpose information. The network device configures different processing manners (first processing manner for L1/L2 controlled mobility, second processing manner for RRC controlled mobility) based on the mobility purpose, allowing the system to adapt its complexity and behavior dynamically rather than using a static configuration for all cases.
Solution Approach 2:
The patent changes the processing parameters of transmission entities based on the mobility procedure purpose. By introducing purpose information and configuring different processing manners accordingly, the system modifies how transmission entities are processed (e.g., whether to reset MAC entity, how to handle L2 entities) depending on the specific mobility scenario, thereby preventing data loss without uniformly increasing complexity.
2Loss of time
If static RRC configuration is used for transmission entity processing, then device complexity is reduced, but interruption time increases during cell changes
Solution Approach 1:
The patent enables dynamic adaptation of processing procedures based on mobility purpose information. By configuring different processing manners for different mobility scenarios (L1/L2 controlled vs. RRC controlled mobility), the system can optimize interruption time for each specific case rather than using a one-size-fits-all static approach, thereby reducing overall interruption time without uniformly increasing complexity.
Solution Approach 2:
The patent applies preliminary action by configuring processing manners in advance based on mobility purpose information. The network device pre-configures how transmission entities should be processed for different mobility scenarios, allowing the terminal device to execute the appropriate processing immediately when a mobility procedure is triggered, thereby reducing interruption time without requiring complex real-time decisions.
3Reliability
If dynamic processing based on mobility purpose is implemented, then data loss is reduced and reliability is improved, but device complexity increases
Solution Approach 1:
The patent enables the terminal device to autonomously determine the appropriate processing manner for transmission entities based on received mobility purpose information. The terminal device self-services by selecting and executing the correct processing procedure (first or second processing manner) without requiring complex external control, thereby improving reliability while keeping the operation relatively simple through automated decision-making.
4Loss of time
If dynamic processing based on mobility purpose is implemented, then interruption time is reduced, but device complexity increases
Solution Approach 1:
The patent reduces interruption time by pre-configuring processing manners for different mobility scenarios. The network device provides mobility purpose information and corresponding processing configurations in advance, allowing the terminal device to immediately execute the appropriate processing when mobility is triggered, thereby minimizing interruption time while avoiding the need for complex real-time analysis.
