Wireless Repeater Terminal Assignment via Invitation Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assigning a wireless terminal to a repeater in wireless LANs face security concerns and communication obstruction issues, particularly when using broadcasted SSID and passwords, and require button operations that are cumbersome for users, especially when the access point is not easily accessible.
Innovation Solution
A wireless communication system where an assigned terminal initiates a connection start request to an unassigned terminal after receiving a presence notification, allowing secure and easy assignment without physical button operations, using presence notifications and invitation requests to manage the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If SSID and encrypted password are broadcast from an assigned terminal, then unassigned terminals can be easily assigned to the access point, but security is compromised due to easy communication interception in wireless LAN
Solution Approach 1:
The patent extracts the password transmission from public broadcast and replaces it with unicast communication. The access point sends the password individually to each unassigned terminal through the assigned terminal, preventing eavesdropping while maintaining ease of assignment.
Solution Approach 2:
The assigned terminal acts as an intermediary that receives the password from the access point and forwards it to unassigned terminals. This intermediary mechanism enables secure password distribution without requiring public broadcasting, thus maintaining both security and ease of operation.
2Ease of operation
If button pressing scheme is used for easy connection, then connection can be initiated, but access point and wireless terminal must be present at near positions which limits applicability
Solution Approach 1:
The patent replaces the mechanical button pressing system with a wireless communication system. Unassigned terminals can initiate connection requests and receive passwords through wireless communication without requiring physical proximity to the access point, thus maintaining ease of connection while enabling spatial flexibility.
3Ease of operation
If assigned terminal performs wireless LAN communication with unassigned terminal, then assignment can be achieved, but the assigned terminal is disconnected from the access point causing communication obstruction
Solution Approach 1:
The patent uses preliminary action by having the access point prepare and send the password to the assigned terminal before the assigned terminal needs to communicate with the unassigned terminal. This allows the assigned terminal to forward the password without disconnecting from the access point, maintaining communication continuity while enabling assignment.

AI summary
The present invention is intended to provide a method which does not cause degradation of security and communication obstruction in an assigned terminal and is not limited by a button operation when an unassigned terminal is assigned to a repeater by use of the assigned terminal. A wireless communication system according to the present invention comprises: a wireless-communication repeater; and first and second wireless terminals for wirelessly communicating with the repeater, wherein, when the first wireless terminal is assigned to the repeater, and the second wireless terminal attempts to be assigned to the repeater, the second wireless terminal transmits a presence notification; when receiving the presence notification, the first wireless terminal transmits an invitation request based on the presence notification to the repeater; when receiving the invitation request, further receiving the presence notification, and confirming that the invitation request and the presence notification both pertain to the second wireless terminal, the repeater transmits a connection start request to the second wireless terminal; when receiving the connection start request, the second wireless terminal transmits a connection start response to the repeater; and connection is started between the repeater and the second wireless terminal.
