Dynamic Error Mitigation in 5G Dual Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networked computer systems, the complexity of multiple access points with varying connection qualities due to different frequency bands, antenna placements, and transmitting power leads to communication errors, which existing error mitigation approaches inadequately address, especially in scenarios with dual connectivity using LTE and NR technologies.
Innovation Solution
Implementing a system that dynamically changes error mitigation protocols based on network connection conditions by using linear network coding and a compensation factor to adjust redundancy, allowing for efficient error handling and minimizing overhead in dual connectivity scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional error mitigation approaches are used in dual connectivity scenarios, then communication errors can be handled, but system overhead increases and performance degrades in poor signal conditions
Solution Approach 1:
The patent implements dynamic error mitigation by switching between different error handling mechanisms based on connection conditions. The system dynamically adjusts the error mitigation approach for the NR connection depending on signal quality, transitioning between no error mitigation, selective error mitigation, and robust error mitigation modes. This dynamic adaptation resolves the contradiction by applying error mitigation only when necessary, thereby maintaining reliability while minimizing overhead.
Solution Approach 2:
The system changes error mitigation parameters based on connection quality metrics. When signal quality deteriorates below thresholds, the system modifies error mitigation parameters such as enabling retransmission mechanisms or adjusting coding schemes. This parameter-based adaptation allows the system to maintain effective error mitigation during poor signal conditions while avoiding unnecessary overhead during good signal conditions.
2Reliability
If error mitigation is always applied to ensure reliability, then data delivery accuracy improves, but network overhead and latency increase
Solution Approach 1:
The patent implements conditional error mitigation where the system dynamically enables or disables error mitigation mechanisms based on real-time connection quality assessment. During good signal conditions, error mitigation is minimized or disabled, reducing latency and overhead. During poor signal conditions, error mitigation is activated to ensure data delivery accuracy. This dynamic approach resolves the contradiction by applying error mitigation only when the time cost is justified by the reliability benefit.
3Reliability
If multiple error mitigation mechanisms are deployed simultaneously, then error handling capability improves, but system complexity and resource consumption increase
Solution Approach 1:
The system dynamically selects and activates error mitigation mechanisms based on connection conditions rather than deploying all mechanisms simultaneously. The LTE connection serves as an anchor with established error handling, while the NR connection's error mitigation is dynamically adjusted based on signal quality. This selective dynamic activation reduces processing resource consumption while maintaining adequate error handling capability.
Solution Approach 2:
The patent applies different error mitigation qualities to different connections based on their specific needs. The LTE connection receives standard error mitigation appropriate for its characteristics, while the NR connection receives adaptive error mitigation tailored to its signal conditions. This localized quality approach ensures adequate error handling for each connection type without uniformly applying complex mitigation to all connections, thereby reducing overall processing resources.

AI summary
The technologies described herein are generally directed to changing error mitigation protocols used for a connection based on the quality of a network connection in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include determining, by network equipment comprising a processor, that a quality of a connection between a user equipment and a network access point is below a connection quality threshold, with the connection employing a communications protocol using a first error mitigation process, and where the network access point enables respective access to services enabled via a communication network. The method can further include, based on the quality and the first error mitigation process, enabling, by the network equipment, a second error mitigation process of the communications protocol of the connection, the second error mitigation process being different than the first error mitigation process.
