SSID Priority-Based Resource Unit Allocation in 802.11ax Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 802.11ax protocol systems, network traffic from one type of connection can occupy valuable throughput, limiting it for other types and reducing the benefits of orthogonal frequency-division multiple access (OFDMA) for connected devices, leading to potential service interruptions or degradation.
Innovation Solution
Implementing a priority SSID protocol that dynamically allocates resource units based on designated priority statuses, prioritizing higher-priority SSIDs by allocating more resources and potentially reallocating or restricting resources for lower-priority SSIDs, ensuring uninterrupted service for high-priority connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If resource units are allocated based on equal distribution among all SSIDs, then fairness is improved, but throughput for high-priority traffic deteriorates
Solution Approach 1:
The patent applies local quality by differentiating resource allocation based on SSID priority levels. High-priority SSIDs receive preferential treatment in resource unit allocation, while low-priority SSIDs receive standard allocation. This is implemented through the network device identifying priority levels for different SSIDs and allocating RUs accordingly, ensuring that critical traffic receives sufficient resources while maintaining a baseline level of service for all connections.
Solution Approach 2:
The patent implements dynamics by making resource unit allocation adaptive rather than static. The network device continuously monitors network conditions, device requirements, and priority levels to dynamically adjust RU allocation. This allows the system to respond to changing traffic patterns and ensure high-priority traffic receives adequate resources while preventing any single SSID from monopolizing the medium.
2Productivity
If OFDMA resources are allocated to multiple SSIDs simultaneously, then resource utilization is improved, but service quality for individual SSIDs deteriorates
Solution Approach 1:
The patent applies local quality by assigning different service quality levels to different SSIDs based on their priority designations. High-priority SSIDs are guaranteed sufficient resource units to maintain high service quality, while low-priority SSIDs operate with standard quality levels. This differentiation allows the system to maintain high resource utilization through OFDMA while ensuring that critical services receive the quality they require.
Solution Approach 2:
The patent implements preliminary action by pre-designating priority levels for different SSIDs before resource allocation occurs. The network device identifies and categorizes SSIDs into priority levels in advance, allowing it to make informed resource allocation decisions. This preliminary classification ensures that when OFDMA resources are distributed, high-priority traffic is already positioned to receive adequate resources, preventing service quality degradation.
3Device complexity
If resource units are allocated without priority consideration, then system simplicity is improved, but performance for critical traffic deteriorates
Solution Approach 1:
The patent applies local quality by implementing priority-based resource allocation specifically for high-priority SSIDs while maintaining standard allocation for others. This targeted approach adds complexity only where necessary - in the identification and preferential treatment of high-priority traffic - rather than requiring a complete overhaul of the allocation system. The network device maintains the ability to allocate RUs to all SSIDs but applies enhanced logic only when high-priority traffic is detected.

AI summary
Devices, methods, and systems for implementing an 802.11ax communication protocol. A first wireless connection is established between a first device and a network device in association with a first service set identifier. A second wireless connection is established between a second device and a network device in association with a second service set identifier. The network device communicates with the first device over the first wireless connection according to an 802.11ax communication protocol. Full allocation of remaining resource units to the second wireless connection according to the 802.11ax communication protocol is denied based on a priority status of the second service set identifier.
