Dynamic Network Access Control for Wi-Fi Terminal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network devices, such as Wi-Fi devices, cannot automatically adjust the number of accessible terminals based on the network quality, leading to poor network performance and speed issues when the network state is poor, as they continue to allow multiple terminals to access the network until the limit is reached, failing to guarantee the network speed requirements of each user.
Innovation Solution
A network access control method and device that assess the network transmission state between the network device and terminals, dynamically adjusting access control parameters, such as maximum terminal access and identifier broadcast enabling parameters, to match the current network state, ensuring that normal network requirements are met by controlling the number of accessible terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device allows multiple terminals to access simultaneously until the maximum number is reached, then the network coverage and accessibility are improved, but the network speed and quality for each terminal deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of the maximum terminal access number based on real-time network conditions. The network device continuously monitors network quality metrics (signal strength, interference levels, bandwidth availability) and automatically adjusts the access limit parameter accordingly. When network quality is good, more terminals are allowed to access; when quality deteriorates, the access limit is reduced, ensuring each terminal receives sufficient network resources for maintaining acceptable speed and performance.
Solution Approach 2:
The patent changes the key parameter of maximum terminal access number from a fixed static value to a dynamic variable that adapts to network conditions. By modifying this parameter based on real-time measurements of signal quality, bandwidth utilization, and terminal performance, the system optimizes the balance between network accessibility and individual terminal speed, preventing both overloading and underutilization of network resources.
2Reliability
If the network device continues to broadcast and allow access when network state is poor, then the network availability is maintained, but the network quality and user experience worsen
Solution Approach 1:
The patent applies preliminary anti-action by proactively reducing the maximum terminal access number before network quality severely deteriorates. The system monitors network state indicators and predicts potential quality issues, then preemptively adjusts the access limit to prevent harmful overloading. This anticipatory adjustment stops terminals from accessing under poor conditions, thereby maintaining overall network availability while preventing quality degradation that would harm user experience.
3Device complexity
If the network device uses a fixed maximum access limit, then the device complexity is reduced, but the adaptability to different network states deteriorates
Solution Approach 1:
The patent implements self-service by enabling the network device to automatically monitor its own network state and autonomously adjust the maximum terminal access number without external intervention. The device incorporates built-in monitoring functions that track signal quality, bandwidth usage, and terminal performance, then automatically modifies access control parameters based on these measurements. This self-adjusting mechanism provides high adaptability to varying network conditions while adding minimal complexity, as the adjustment logic is integrated into the device's existing control system.
