Wireless Controller Access Point Traffic Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network control systems, such as EDCA, face challenges in managing traffic flow and ensuring communication quality when unmanaged terminals connect to the same access point, leading to packet collisions and poor quality control.
Innovation Solution
A control system and method where a controller notifies an access point of managed terminals, allowing the access point to suppress transmission permissions for unmanaged terminals, preventing packet collisions and ensuring quality control by collating information and managing transmission permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a controller allocates communication band based on packet amount notification from managed terminals, then communication quality control is achieved for managed terminals, but packet collisions occur when unmanaged terminals are connected to the same access point
Solution Approach 1:
The access point serves as an intermediary between the controller and terminals. It receives terminal information from the controller, collates it with connected terminal information, and suppresses transmission permission notifications to unmanaged terminals. This intermediary role prevents packet collisions while maintaining communication quality control for managed terminals.
2Adaptability or versatility
If EDCA priority control is implemented on terminal basis, then existing wireless control is maintained, but traffic flow control on service and application basis becomes difficult
Solution Approach 1:
The control mechanism is segmented into two layers: the controller handles high-level traffic flow control based on service and application requirements by managing communication band allocation, while the access point handles low-level transmission permission control by suppressing notifications to unmanaged terminals. This segmentation enables service-level quality control without excessive complexity in the access point.

AI summary
An object of the present disclosure is to perform appropriate communication quality control even when a terminal out of management of a controller is connected to an access point.The present disclosure is a control system for controlling traffic of a wireless network, the control system including: a terminal and an access point that mutually transmit a packet via the wireless network; and a controller that performs transmission control with respect to the terminal and the access point, in which the controller notifies the access point of information of a terminal under management of the own device, and the access point collates information of the terminal a notification of which has been given with information of a terminal connected to the own device, and suppresses notification of transmission permission to an unmanaged terminal different from a terminal under management of the controller.
