First Node Bandwidth Redistribution for QoS in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to provide guaranteed bitrate and quality of service (QoS) in communications networks, especially in crowded areas, leading to decreased data upload and download speeds and customer dissatisfaction, due to the lack of real-time analytics and resource management capabilities.
Innovation Solution
A method involving a first node and a third node in a communications network that determine and redistribute bandwidth in real-time based on quality of service thresholds, using Machine Learning (ML) and 5G analytics to collect and analyze data from Network Functions such as SMF, PCF, and UPF, ensuring dynamic adjustments to maintain QoS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth is statically allocated in communications networks, then network management is simple, but quality of service degrades in crowded areas leading to decreased data speeds
Solution Approach 1:
The patent implements dynamic bandwidth allocation where the network function continuously monitors QoS parameters and automatically redistributes bandwidth based on real-time network conditions. This allows the system to adapt to varying traffic loads and maintain QoS in crowded areas without manual intervention, resolving the contradiction between QoS reliability and management complexity.
Solution Approach 2:
The system employs feedback mechanisms by collecting QoS data from the network, analyzing it through machine learning models, and using the insights to adjust bandwidth allocation. This closed-loop control ensures QoS is maintained while automating the management process, thereby improving reliability without proportionally increasing operational complexity.
2Reliability
If real-time analytics and bandwidth redistribution are implemented, then quality of service is maintained in crowded areas, but system complexity and processing requirements increase
Solution Approach 1:
The patent introduces a specialized network function as an intermediary that handles the complex analytics and decision-making processes. This intermediary componentizes the complexity, isolating it from the core network infrastructure and making it easier to manage and update without affecting the entire system. The intermediary processes QoS data, generates redistribution decisions, and implements them, thereby maintaining QoS while managing complexity through modular architecture.
3Productivity
If bandwidth is redistributed dynamically based on real-time conditions, then data speeds are maintained, but response time for detection and action increases
Solution Approach 1:
The system performs preliminary actions by continuously monitoring QoS parameters and predicting potential degradations before they occur. The machine learning models analyze trends and anticipate congestion, allowing the system to proactively redistribute bandwidth before QoS actually degrades. This preventive approach maintains data speeds while minimizing the time lost to actual QoS events.
Solution Approach 2:
The patent implements continuous QoS monitoring and analysis, ensuring that the system is always ready to detect and respond to changing conditions. By maintaining continuous operation of the analytics engine and bandwidth management functions, the system eliminates gaps in protection and ensures rapid response to any QoS threats, thereby maintaining productivity without significant time loss.
Data Source
AI summary
A method performed by a first node for handling quality of service in a communications network. The first node determines, in real time, whether a respective quality of service threshold is predicted to be exceeded or underachieved in communications provided to one or more communication devices operating in a communications network. The determining is based on one or more first indications received, in real time, from one or more second nodes. The one or more first indications indicate, in real time, one or more respective quality of service parameters for the communications provided to the one or more communication devices. The first node initiates a redistribution of a bandwidth available to at least one of the one or more communication devices. The initiation of the redistribution is based on a result of the determination.
