Solution Overview

Problem

Conventional load balancing in telecommunication systems fails to accurately account for available bandwidth, leading to unbalanced load distribution between frequency bands, which can result in inefficient utilization of bandwidth capacity.

Innovation Solution

Adjusting load determination based on channel width and duplexing scheme for each frequency band, and then balancing loads by instructing wireless devices to change frequency bands, thereby optimizing load distribution according to available bandwidth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional load balancing is used based on percentage utilization, then load distribution is simplified, but bandwidth capacity utilization becomes inefficient

Engineering Contradiction:

Improveload balancing operationVSAvoidbandwidth capacity utilization

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent transforms the load balancing parameter from simple percentage utilization to an adjusted load metric that incorporates channel width and duplexing scheme characteristics. This parameter change enables the system to account for the actual bandwidth capacity of each frequency band, allowing load to be balanced according to true capacity rather than uniform percentages, thereby improving bandwidth utilization efficiency.

2Device complexity

If load balancing ignores channel width and duplexing scheme, then calculation is simpler, but load distribution accuracy deteriorates

Engineering Contradiction:

Improveload balancing calculationVSAvoidload distribution accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent introduces additional parameters (channel width and duplexing scheme) into the load balancing calculation to improve accuracy. The adjusted load for each frequency band is computed by combining the determined load with these additional parameters, creating a more precise metric that reflects actual bandwidth capacity and enables more accurate load distribution decisions.

3Ease of operation

If frequency bands are treated uniformly, then management is easier, but bandwidth capacity is not fully utilized

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent applies local quality by treating each frequency band according to its specific characteristics (channel width and duplexing scheme) rather than uniformly. Each band receives an adjusted load calculation tailored to its capacity, allowing the system to optimize load distribution for each band's specific bandwidth capabilities while maintaining manageable complexity through automated calculations.

AI summary

Systems and methods are described for load balancing between frequency bands based on bandwidth capacity. A load for a first frequency band and a load for a second frequency band may be determined, wherein a cell communicates with wireless devices over the first and second frequency bands. The determined loads may be adjusted based on a channel width for each frequency band and a duplexing scheme for each frequency band. And the adjusted loads may be balanced between the first frequency band and the second frequency band by instructing wireless devices in communication with the cell to change frequency bands used for communicating with the cell.
