Carrier Load Balancing Using Throughput-Based Wireless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier aggregation techniques fail to effectively balance load between primary and secondary carriers, particularly in scenarios with bursty traffic, leading to inefficient data throughput.
Innovation Solution
A system and method that determines user device connectivity across carriers based on estimated throughput, allowing for dynamic switching between carriers to rebalance load and improve data throughput by disconnecting from a less efficient carrier and connecting to a more efficient one.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carrier aggregation is used to increase data throughput, then throughput is improved, but load imbalance between primary and secondary carriers occurs
Solution Approach 1:
The patent implements dynamic carrier switching by continuously monitoring throughput estimates and automatically transitioning user devices between primary and secondary carriers based on real-time performance conditions. This dynamic adjustment resolves the load imbalance problem while maintaining high throughput by making the carrier configuration adaptive rather than static.
Solution Approach 2:
The system changes the operational state of carrier connections by disconnecting from the primary carrier and connecting to the secondary carrier based on throughput estimates. This parameter change in connectivity configuration allows load redistribution between carriers, addressing the load balancing issue while preserving overall system throughput.
2Reliability
If user devices remain connected to primary carrier, then connection stability is maintained, but throughput efficiency decreases under load imbalance
Solution Approach 1:
The patent introduces dynamic carrier selection that adapts connection stability requirements to current load conditions. When the primary carrier becomes overloaded, the system dynamically switches to the secondary carrier, maintaining connection stability through controlled transitions rather than forcing devices to remain on an overloaded primary carrier.
Solution Approach 2:
The system uses throughput estimates as feedback to determine when to switch carriers. By continuously monitoring performance metrics and using this feedback to trigger carrier transitions, the system maintains optimal throughput efficiency while preserving connection stability through data-driven decision-making.
