Probe Response Coordination via Signal Quality and Buffer Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of external electronic devices transmitting probe request frames and access points (APs) receiving these frames increases, the congestion in wireless channels used for transmission and reception of probe response frames and data also increases, leading to inefficiencies in data transmission.
Innovation Solution
An electronic device is equipped with a communication circuit, processor, and memory that allows it to receive information about the quality of probe request frames from multiple APs, select an AP to transmit a probe response frame based on signal quality and buffer status, and control the selected AP to transmit the probe response frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple APs transmit probe response frames to external electronic devices, then the coverage and responsiveness of network connection are improved, but the congestion in wireless channels increases
Solution Approach 1:
The patent introduces a coordination mechanism where a designated AP acts as an intermediary to manage probe response frame transmissions. Instead of all APs transmitting simultaneously, the coordinating AP receives probe request frames and selectively forwards them to appropriate APs, thereby controlling the number of simultaneous transmissions and reducing wireless channel congestion while maintaining network responsiveness.
Solution Approach 2:
The patent implements selective transmission where not all APs that receive probe request frames transmit probe response frames. Instead, only specific APs designated by the coordination mechanism transmit responses, reducing the overall number of transmissions in the wireless channel while still ensuring that external electronic devices can establish connections.
2Reliability
If all APs that receive probe request frames transmit probe response frames, then the probability of successful connection is improved, but the transmission efficiency of data decreases
Solution Approach 1:
The coordination AP serves as an intermediary that receives probe request frames and intelligently directs them to appropriate APs for response transmission. This mediation ensures that external electronic devices receive timely responses (maintaining connection success probability) while controlling the overall transmission load to preserve data transmission efficiency.
Solution Approach 2:
The patent assigns different roles to different APs based on local conditions. The coordinating AP manages the probe request frame distribution, while other APs focus on data transmission. This division of labor allows the system to maintain high connection success rates through coordinated response transmission while preserving overall data transmission efficiency.
3Adaptability or versatility
If the number of APs participating in multi-AP coordination increases, then the network coverage and service capability are improved, but the complexity of managing probe response frame transmissions increases
Solution Approach 1:
The patent segments the functions of multi-AP coordination by designating specific APs as coordinating APs with centralized management responsibilities, while other APs perform simpler local functions. This segmentation allows the network to scale with multiple APs for improved coverage while keeping the management complexity concentrated in the coordinating APs rather than distributed across all APs.
