Network Load Balancing via Resource Utilization Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Networks experience performance degradation due to loading imbalances between cells, which existing management systems fail to correct effectively by focusing on user device quantities rather than resource utilization, leading to congestion and poor service quality.
Innovation Solution
A network management device identifies loaded cells and less loaded neighbor cells based on resource utilization metrics, dynamically altering configurations to offload traffic and balance loads in real-time, reducing the likelihood of congestion and improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing network management systems focus on user device quantities for load balancing, then the system complexity is reduced, but network performance degradation occurs due to loading imbalances between cells
Solution Approach 1:
The patent changes the load balancing parameter from user device quantity to resource utilization metrics. The network management device determines loading of cells based on resource utilization rather than simply counting user devices, which resolves the contradiction by using more accurate parameters to maintain network performance without excessive system complexity
Solution Approach 2:
The patent implements a feedback mechanism where the network management device continuously monitors resource utilization metrics of cells and dynamically adjusts load balancing decisions. This feedback loop enables the system to respond to actual network conditions, improving reliability while maintaining manageable complexity through automated control
2Reliability
If dynamic cell configuration alterations are implemented for real-time load balancing, then network performance is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic cell configuration alterations that allow the network management device to adjust cell parameters in real-time based on current loading conditions. This dynamic approach improves network performance by adapting to changing conditions, while the automation of the process prevents excessive complexity in the management system
Solution Approach 2:
The network management device autonomously monitors resource utilization metrics and performs load balancing decisions without requiring manual intervention. This self-service capability improves network performance through continuous optimization while keeping device complexity manageable by eliminating the need for complex manual configuration systems

AI summary
A device may select a sector of a network on which to perform network traffic offloading based on a sector loading metric relating to an imbalance of loading of a set of cells of the sector. The device may identify a loaded cell of the sector based on one or more call admission metrics or one or more cell congestion metrics. The device may identify a less loaded neighbor (LLN) cell for the loaded cell. The device may cause one or more cell configuration alterations relating to causing network traffic to be offloaded from the loaded cell to the LLN cell.
