Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks experience congestion, leading to reduced bandwidth and data transfer reliability, which existing technologies fail to address effectively.
Innovation Solution
User equipment (UE) is configured to monitor link metrics and switch to alternative communication networks or SIMs when congestion occurs, using predictive algorithms to optimize network usage and maintain high-throughput communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continues to communicate on the congested NR network, then network compatibility is maintained, but data transfer reliability and throughput deteriorate
Solution Approach 1:
The patent implements dynamic network selection by enabling the UE to switch between NR and LTE networks based on real-time congestion conditions. The system dynamically adjusts the communication network used by monitoring link metrics and automatically transitioning to an alternative network when congestion is detected, thereby maintaining reliability while adapting to changing network conditions.
Solution Approach 2:
The patent changes the operational parameter of the communication system by switching between different network types (NR and LTE) based on congestion parameters. When link metrics indicate congestion on the NR network, the system changes the active communication parameter to use the LTE network instead, thus maintaining data transfer reliability under varying network conditions.
2Reliability
If the UE switches to alternative networks frequently, then data transfer reliability improves, but communication interruption increases
Solution Approach 1:
The patent applies preliminary action by predicting network congestion before it fully impacts data transfer. The system monitors link metrics and predicts upcoming congestion, allowing the UE to switch to an alternative network in advance. This proactive approach ensures seamless communication by completing the switch before data transfer is interrupted, thereby improving reliability while minimizing communication interruption time.
3Measurement precision
If the UE monitors link metrics continuously, then congestion detection accuracy improves, but energy consumption increases
Solution Approach 1:
The patent applies partial action by monitoring link metrics selectively rather than continuously. The system monitors congestion indicators such as signal-to-noise ratio and bandwidth availability, and only triggers a network switch when specific threshold conditions are met. This selective monitoring approach maintains adequate congestion detection accuracy while reducing unnecessary energy consumption from continuous monitoring.
