Link Management for Connected User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management systems face challenges in dynamically switching communication links between user equipment (UE) and base stations, particularly in determining when to switch from a direct communication link to a UE-to-network relay or vice versa, which can affect communication quality and efficiency.
Innovation Solution
A method and system at the base station for transmitting configuration information to remote UE, determining the need to switch communication links, and sending messages to trigger the necessary link changes, including switching between direct and relay links, based on measurement data and preference information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network uses a static configuration for UE communication links, then the system complexity is reduced, but the communication quality and efficiency deteriorate when link conditions change
Solution Approach 1:
The patent implements dynamic link management where the network can switch between direct communication links and relay communication links based on real-time conditions. The base station receives measurement data from UEs, evaluates link quality, and dynamically determines whether to maintain direct links or switch to relay links through structured message exchanges, allowing the system to adapt to changing communication conditions while maintaining manageable complexity through standardized procedures.
2Reliability
If the network dynamically switches between direct and relay communication links, then communication quality is improved, but the system complexity and signaling overhead increase
Solution Approach 1:
The patent segments the link management process into distinct phases: measurement data collection by UEs, evaluation by the base station, and execution of link switching through structured message exchanges. This segmentation allows complex dynamic switching to be managed through modular, standardized procedures, reducing overall system complexity while maintaining communication quality.
Solution Approach 2:
The patent implements feedback mechanisms where UEs provide measurement data about link conditions to the base station, which then makes informed decisions about link switching. This feedback-driven approach enables quality-based dynamic switching while keeping complexity manageable through automated decision-making based on objective metrics rather than manual configuration.
3Reliability
If the network switches to relay communication, then coverage and connectivity are improved, but the transmission speed and latency worsen due to additional relay hops
Solution Approach 1:
The patent dynamically selects between direct and relay communication modes based on real-time link conditions. When direct links are available and quality is sufficient, the system uses direct communication for optimal speed. When direct links are unavailable or quality degrades below thresholds, the system switches to relay communication to maintain connectivity, accepting the speed trade-off only when necessary for connectivity.
