Engineering Contradiction Analysis
1Productivity
If existing wireless communication systems use fixed radio link management protocols, then system simplicity is maintained, but communication efficiency and resource utilization deteriorate in heterogeneous networks
Solution Approach 1:
The patent implements dynamic radio link management by enabling the network to switch between different radio link monitoring and failure detection methods based on real-time network conditions and device capabilities. The system transitions from fixed protocols to adaptive protocols that adjust monitoring granularity, failure criteria, and resource allocation dynamically, resolving the contradiction between simplicity and efficiency in heterogeneous networks.
Solution Approach 2:
The system changes key parameters such as radio link monitoring frequency, failure threshold criteria, and resource allocation ratios based on network load and device type. By adjusting these parameters dynamically, the system achieves higher communication efficiency without requiring complete protocol redesign, thus improving productivity while controlling complexity.
2Productivity
If radio link management uses uniform protocols for all cell types, then system simplicity is maintained, but resource utilization deteriorates in heterogeneous networks
Solution Approach 1:
The patent applies local quality by tailoring radio link management parameters to specific cell types and device capabilities. Different monitoring strategies are applied to different network scenarios (e.g., high-monitoring for critical links, low-monitoring for tolerant links), enabling optimized resource utilization in heterogeneous networks while maintaining overall system manageability.
Solution Approach 2:
The system dynamically adapts radio link management behavior based on real-time conditions including device capability reports, network load, and link importance. This dynamic adaptability allows the system to optimize resource utilization across heterogeneous networks without requiring complex static configurations for every possible scenario.
3Reliability
If radio link monitoring is performed with high granularity, then link reliability is improved, but system complexity and processing overhead increase
Solution Approach 1:
The system dynamically adjusts monitoring granularity based on link importance and network conditions. Critical links receive high-granularity monitoring with frequent measurements and strict failure criteria, while less critical links use low-granularity monitoring. This dynamic approach improves reliability where needed without uniformly increasing system complexity across all links.
Solution Approach 2:
The patent segments radio link monitoring into different levels and types (e.g., physical layer monitoring, MAC layer monitoring, higher layer monitoring) with different granularity requirements. By segmenting the monitoring function, the system can apply appropriate monitoring intensity to different link segments, improving overall reliability while controlling processing overhead through selective monitoring.
