Load Balancing for Fixed Wireless Grade of Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed wireless services struggle to maintain high data rates and reliable network performance due to fluctuations in usage patterns and increased demand, leading to disruptions and degradation in service quality, especially in areas without wired connections.
Innovation Solution
Implementing a load balancing application that manages network traffic by transferring data between base stations to ensure a target Grade of Service (GOS) is maintained, using real-time and historical traffic conditions, and adaptive beam control to select optimal communication paths based on signal quality and capacity thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If fixed wireless services are deployed to areas without wired connections, then service coverage is expanded, but network performance and data rates degrade under increased demand and usage fluctuations
Solution Approach 1:
The patent implements dynamic load balancing that continuously monitors network conditions and adjusts traffic distribution in real-time. The system transitions from static to dynamic resource allocation, allowing the network to adapt to fluctuating usage patterns and maintain performance stability across expanded coverage areas.
Solution Approach 2:
The system changes operational parameters by adjusting load distribution thresholds, GOS targets, and traffic routing decisions based on real-time network conditions. These parameter adjustments enable the network to maintain reliability while serving expanded geographic areas with varying demand characteristics.
2Quantity of substance
If more households use fixed wireless services, then service adoption increases, but data rates and network performance become difficult to maintain
Solution Approach 1:
The patent segments network traffic into different categories (e.g., GOS-critical and non-critical traffic) and applies different handling strategies to each segment. This segmentation allows the system to prioritize performance-critical traffic while accommodating increased overall network usage without compromising data rates for essential services.
Solution Approach 2:
The load balancing system operates autonomously by automatically monitoring network conditions, making routing decisions, and adjusting load distribution without manual intervention. This self-service capability enables the network to efficiently handle increasing household connections while maintaining data rate performance through automated resource optimization.
3Reliability
If load balancing is implemented to maintain target GOS, then service quality is maintained, but network complexity increases
Solution Approach 1:
The patent implements a feedback-driven load balancing system that continuously monitors network performance metrics and GOS compliance, then automatically adjusts traffic routing decisions based on this feedback. This closed-loop control maintains target GOS levels while managing complexity through automated, rule-based responses to performance variations.
Solution Approach 2:
The system performs preliminary actions by pre-configuring load balancing policies, GOS thresholds, and routing rules before network operations begin. These pre-established parameters and decision frameworks reduce operational complexity by providing clear guidance for load balancing decisions without requiring complex real-time computations.

AI summary
A method includes receiving metrics associated with traffic that complies with a grade of service (GOS) associated with a customer premises equipment (CPE) device, where the metrics identify a group of cells via which the traffic is received by the CPE device. The method also includes retrieving information associated with traffic conditions within a group of base stations; initiating a load balancing operation when traffic conditions within a base station indicate that a particular cell, associated with the base station, is congested; and sending, to a set of base stations that send traffic to the CPE device, a notification, where the notification causes traffic, not destined for the CPE device, to be rerouted to another base station, which enables the base station to send traffic, that complies with the GOS, to the CPE device, or causes the CPE device to receive traffic, that complies with the GOS, from a further based station.
