Access Point Authentication Query for Station Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing network infrastructure, stations need to perform separate authentication and association processes with multiple service devices, which is cumbersome and inefficient, especially when switching between or using multiple services simultaneously.
Innovation Solution
An authentication and association method where an access point receives an authentication result query request from a service device to determine if a station is authenticated, allowing the service device to establish an association with the station without performing separate authentication processes with each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a station performs separate authentication and association with each service device, then each connection can be established independently, but the authentication process becomes cumbersome and time-consuming
Solution Approach 1:
The access point performs authentication with the station beforehand, and the authentication information is stored in advance. When the station needs to connect to service devices, the service devices query the access point for pre-stored authentication information, eliminating the need for repeated authentication processes.
Solution Approach 2:
The access point acts as an intermediary that manages authentication information. Service devices query the access point to obtain authentication status of stations, allowing service devices to establish associations without directly performing authentication with each station.
2Reliability
If a station performs separate authentication with each service device, then authentication can be performed individually, but the process complexity increases significantly
Solution Approach 1:
Multiple authentication processes are merged into a single authentication interaction between the station and access point. The access point consolidates authentication management and provides authentication information to multiple service devices simultaneously, reducing overall process complexity.
Solution Approach 2:
The access point serves multiple functions: it performs initial authentication with the station, stores authentication information, and provides authentication status to multiple service devices. This multi-functional approach simplifies the overall system architecture.
3Adaptability or versatility
If service devices perform authentication separately with each station, then each service can be accessed independently, but the user experience deteriorates due to repeated authentication
Solution Approach 1:
Service devices automatically query authentication information from the access point without requiring user intervention for each authentication. The system performs self-service authentication verification, allowing users to access multiple services without repeatedly providing authentication credentials.
Data Source
AI summary
This application discloses an authentication and association method and system. An access point AP receives an authentication request sent by a station STA that needs to establish a connection to a service device; the AP establishes authentication with the STA; after the STA sends an association request to the service device, the AP receives an authentication result query request sent by the service device, and sends a result of the authentication result query request to the service device, so that the service device determines whether to establish an association with the STA; if the result shows that the STA is authenticated by the AP, the service device can establish an association with the STA; or if the result shows that the STA fails to be authenticated by the AP, the STA cannot establish an association with the service device.
