Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay communication is implemented without centralized configuration, then UE autonomy and flexibility are improved, but connection mode mismatches and communication failures increase
Solution Approach 1:
The core network device acts as an intermediary between UEs, receiving relay mode selection requests from UEs and providing configured relay modes back to them. This mediator ensures that relay mode selection is both autonomous (UE-initiated) and reliable (network-configured), resolving the contradiction between UE autonomy and connection success rate.
Solution Approach 2:
The core network device performs preliminary configuration of relay modes before actual relay communication occurs. By pre-configuring the relay modes and providing them to UEs in advance, the system ensures that when relay communication is established, the modes are already aligned, preventing mismatches and ensuring reliable connection establishment.
2Device complexity
If each UE independently determines relay modes, then system complexity is reduced, but mode consistency across multiple UEs deteriorates
Solution Approach 1:
The patent merges the relay mode determination function from individual UE-level decisions to a centralized core network device. By combining the mode selection logic at the network level, the system maintains low complexity at the UE level while achieving consistent relay mode composition across all UEs through centralized coordination.
3Reliability
If relay mode configuration is added to the core network device, then relay communication reliability is improved, but network device functionality and complexity increase
Solution Approach 1:
The core network device already performs multiple functions including authentication, authorization, and session management. Adding relay mode configuration to these existing functions leverages the device's multi-functionality, avoiding the need for separate dedicated components while enhancing relay communication reliability through integrated control.
