Wireless LAN Controller SSID Allocation for Flow Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual or site-based setting of SSIDs in wireless LAN communication is cumbersome and complicated, leading to difficulties in connecting to access points and managing wireless LAN services.
Innovation Solution
A network communication system where a controller automatically determines and sets the SSID for each flow in a terminal, allowing dynamic changes and simplifying the SSID setting process, and can be used to manage different SSIDs for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual or site-based setting of SSID is used, then the terminal can connect to access points, but the setting process becomes troublesome and complicated
Solution Approach 1:
The terminal automatically obtains SSID information from the server without requiring manual user input or site-based configuration. The terminal self-configures by receiving SSID data through communication with the server, eliminating the need for users to manually set SSIDs and thereby simplifying the operation process.
Solution Approach 2:
The server acts as an intermediary between the terminal and the SSID configuration process. Instead of direct manual configuration or site-based setting, the terminal communicates with the server which provides the necessary SSID information, thereby simplifying the terminal's operation while maintaining proper network configuration.
2Ease of operation
If automatic SSID setting is implemented, then the operation becomes simpler, but dynamic SSID management for different flows requires controller intervention
Solution Approach 1:
The SSID configuration is made dynamic rather than static. The terminal can automatically obtain different SSID information for different communication flows by communicating with the server. This dynamic approach allows the system to adapt SSID settings based on communication needs while maintaining automated operation, resolving the contradiction between simplicity and flexibility.

AI summary
A network communication system has: a terminal performing communication through a wireless LAN; and a controller. The terminal retains flow SSID information indicating a correspondence relationship between each flow and SSID. When initiating communication of a new flow, the terminal transmits an allocation request to the controller. The allocation request requests for determination of an SSID to be used. In response to the allocation request, the controller determines an allocated SSID to be used regarding the new flow and notifies the terminal of allocation information indicating a correspondence relationship between the new flow and the allocated SSID. In accordance with the allocation information, the terminal registers the correspondence relationship between the new flow and the allocated SSID on the flow SSID information. The terminal refers to the flow SSID information and uses the allocated SSID corresponding to the new flow to connect to an access point of the wireless LAN.
