Wireless Network Load Balancing via Harmonic Mean Throughput Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load balancing techniques in wireless networks often lead to inefficient traffic distribution, causing congestion in some cells and underutilization in others, resulting in a suboptimal user experience due to their focus on network resource utilization rather than user performance.
Innovation Solution
A user-centric approach is employed, using a distribution management component to determine device traffic throughput and resource utilization, adjusting parameters to steer communication devices towards cells that maximize the harmonic mean of user equipment throughput, thereby optimizing traffic distribution and resource utilization.

Engineering Contradiction Analysis
1Quantity of substance
If current load balancing techniques focus on network resource utilization, then network resource distribution is improved, but user equipment throughput and user experience deteriorate
Solution Approach 1:
The patent inverts the traditional load balancing objective from network-centric resource utilization to user-centric throughput optimization. Instead of distributing traffic to balance network resource usage, the system distributes traffic to maximize user equipment throughput by selecting target cells based on user performance metrics rather than network resource availability.
Solution Approach 2:
The patent changes the optimization parameter from network resource utilization metrics to user equipment throughput metrics. The load balancing algorithm transitions from using parameters like resource block utilization and cell capacity to using parameters like user throughput, signal quality, and user experience indicators.
2Object-affected harmful factors
If traffic is distributed to balance network load, then network congestion is reduced, but overall network efficiency and user experience deteriorate
Solution Approach 1:
The patent changes the optimization criterion from load balancing (equalizing traffic distribution) to throughput maximization (optimizing user performance). The system uses user throughput as the key parameter to determine traffic distribution, replacing traditional load balancing parameters like cell utilization and traffic volume.
Solution Approach 2:
The patent implements feedback mechanisms that continuously monitor user equipment throughput and network conditions, using this information to dynamically adjust traffic distribution decisions. The system feeds back user performance metrics to the load balancing algorithm, which adapts its traffic routing to maximize overall user throughput while avoiding congestion.

AI summary
Distribution of traffic to cells in a communication network can be controlled. A distribution management component (DMC) can determine overall device traffic throughput for cells of a sector that satisfy a defined traffic throughput criterion relating to a harmonic mean of the device traffic throughput for the cells to desirably enhance or maximize the harmonic mean of the overall device traffic throughput. Based on the overall device traffic throughput for the cells, the DMC can determine whether to adjust a characteristic associated with a cell of the cells to facilitate adjusting distribution of device traffic among the cells of the sector to achieve desirable load balancing of traffic by the sector and in the network. Load balancing can be achieved by controlling respective parameters with regard to communication devices that are in idle mode or connected mode to facilitate directing communication devices and associated traffic to desired cells.
