Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing wireless communication systems manage layer 1 and layer 2 triggered mobility in dual connectivity, then basic mobility function is provided, but resource allocation efficiency deteriorates and network performance is suboptimal
Solution Approach 1:
The patent modifies existing mobility management parameters and procedures by introducing enhanced configuration mechanisms that change how mobility events are handled. The system updates configuration parameters during mobility transitions to optimize resource allocation, transforming the traditional mobility management approach to achieve both efficiency and reliability improvements in dual connectivity scenarios
2Productivity
If advanced protocol stacks are utilized to handle mobility, then mobility management efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal mobility management mechanism that handles multiple mobility scenarios (layer 1 triggered, layer 2 triggered, and traditional handovers) through a single enhanced configuration framework. This multi-functional approach consolidates complexity into a unified system rather than requiring separate specialized handlers for each mobility type, thereby improving efficiency without proportionally increasing complexity
3Reliability
If handover processes are optimized, then network performance is improved, but configuration handling complexity increases
Solution Approach 1:
The patent applies preliminary configuration actions by pre-establishing mobility configurations and parameters before actual handover events occur. The system prepares configuration templates and pre-configures mobility parameters in advance, so that when mobility events trigger, the handling process follows predetermined optimized paths, improving network performance while containing configuration handling complexity within manageable boundaries
