Supplemental Scheduling Server for WLAN Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area network (WLAN) technologies, such as 802.11ax, face challenges in efficiently allocating time-frequency divisions among multiple user devices, leading to suboptimal resource utilization and potential interference, as they rely on manual scheduling and lack real-time telemetry data for dynamic allocation.
Innovation Solution
A data network with a supplemental scheduling server that collects telemetry data from access points to generate scheduling information, enabling user devices and access points to dynamically allocate time-frequency divisions based on user device requirements and network conditions, using a scheduler and preference engine to optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual scheduling is used to allocate time-frequency divisions, then device complexity is reduced, but resource utilization becomes suboptimal and interference increases
Solution Approach 1:
A supplemental scheduling server is introduced as an intermediary component that collects telemetry data from multiple access points and generates supplemental scheduling information. This mediator enables access points to make more informed scheduling decisions without significantly increasing their own complexity, thereby improving resource utilization while maintaining manageable device complexity.
Solution Approach 2:
The system implements feedback mechanisms by collecting real-time telemetry data from access points about network conditions, user device requirements, and resource allocation status. This feedback loop allows the supplemental scheduling server to continuously optimize scheduling decisions, improving resource utilization and reducing interference through data-driven adjustments.
2Productivity
If dynamic allocation based on real-time telemetry data is implemented, then resource utilization improves, but device complexity and infrastructure requirements increase
Solution Approach 1:
The supplemental scheduling server acts as a centralized intermediary that handles the complexity of data collection, processing, and scheduling optimization. By offloading these complex functions to a dedicated server, individual access points can maintain simpler architectures while still benefiting from sophisticated dynamic allocation based on real-time telemetry data.
3Productivity
If centralized scheduling control is used, then resource allocation optimization improves, but negotiation time and system response latency increase
Solution Approach 1:
The supplemental scheduling server pre-processes telemetry data and generates supplemental scheduling information in advance, preparing optimization recommendations before actual resource allocation decisions are needed. This preliminary action reduces the time required for real-time negotiation, as access points can quickly apply pre-computed scheduling recommendations rather than performing complex calculations during the negotiation process.

AI summary
Systems and methods for allowing multiple user devices to access a wireless local area network are disclosed. A user device receives supplemental scheduling information that is generated based on telemetry data collected from multiple access points of a data network. The user device requests an access point of the data network for accessing the wireless local area network according to a wireless usage type. The wireless usage type is determined based on an application running on the user device and the supplemental scheduling information. The user device receives an allocation of time-frequency divisions for accessing the wireless local area network from the access point.
