Solution Overview
Problem
Conventional wireless communication systems using multi-rate communication struggle to dynamically adjust transmission rates, leading to suboptimal connection establishment even when the base station's connection capacity has a margin, resulting in inefficient use of higher transmission rates.
Innovation Solution
A wireless communication system with a traffic judge module, a transmission rate determining module, and a method change module that dynamically adjusts the threshold for determining transmission rates based on traffic and signal-to-noise ratios, allowing for the use of higher transmission rates when the base station's capacity allows, while maintaining communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a predetermined transmission rate is assigned according to wave intensity, then communication quality is maintained, but connection capacity utilization is inefficient
Solution Approach 1:
The patent applies dynamics by transitioning from static predetermined transmission rate assignment to dynamic transmission rate selection. The base station dynamically determines transmission rates based on real-time traffic load conditions, switching between different rate selection modes (predetermined rates vs. dynamically optimized rates) to adapt to changing network conditions, thereby improving connection capacity utilization while maintaining communication quality.
Solution Approach 2:
The patent changes the parameter of transmission rate selection criteria based on traffic load. When traffic load is below a threshold, the system changes from using fixed predetermined rates to using dynamically calculated optimal rates that maximize connection capacity utilization. This parameter change enables the system to resolve the contradiction between maintaining quality and improving productivity.
2Productivity
If higher transmission rates are used to increase communication speed, then productivity improves, but connection stability deteriorates
Solution Approach 1:
The patent dynamically changes transmission rate parameters based on traffic load conditions. When traffic load is low, the system selects higher transmission rates to maximize communication speed and productivity. When traffic load increases, the system transitions to more conservative rate selection to maintain connection stability. This dynamic parameter adjustment resolves the contradiction between speed and stability.
Solution Approach 2:
The system implements feedback by continuously monitoring traffic load conditions and adjusting transmission rate selections accordingly. The base station receives feedback about current network state and modifies its rate determination strategy in real-time, selecting higher rates when conditions permit (improving productivity) and maintaining stability when load increases, thus resolving the contradiction.

AI summary
By more flexibly controlling connection for each transmission rate in the wireless base station, the connection is established using possibly a higher transmission rate so long as the connection capacity of the wireless base station has a margin while efficiently determining the transmission rate according to the wave intensity from a wireless communication terminal. If the connection capacity of the base station has a margin after additionally connecting one wireless communication terminal, i.e., if the communication traffic is equal to or less than a predetermined margin threshold value, the rate decision threshold value to determine the transmission rate for connection is lowered by a predetermined value to determine a transmission rate so that the connection is established using a transmission rate higher than that determined by the rate decision threshold value as the default value (initial value) to thereafter establish the connection.
