WLAN Terminal Automatic Access Point Selection and Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face operational burdens when moving between wireless local area network (WLAN) access points, requiring manual selection and password re-entry, which is inefficient and inconvenient.
Innovation Solution
A method where a terminal sends a request to a server to query available WLAN access points, receives information, determines a specific access point based on preset criteria, and acquires authentication information to connect automatically, eliminating the need for manual selection and password entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection and password entry methods are used for WLAN access, then users can connect to wireless access points, but users face operational burdens when moving between access points requiring manual selection and password re-entry
Solution Approach 1:
The patent applies preliminary action by having the terminal collect and store WLAN access point information (including SSIDs and passwords) in advance before movement occurs. When the terminal moves to a new location, the pre-collected information enables automatic connection without manual intervention, thus reducing both operational burden and connection setup time
Solution Approach 2:
The patent implements self-service through automatic selection and connection mechanisms. The terminal autonomously queries available access points, selects appropriate ones based on stored information, and automatically authenticates using pre-stored passwords, eliminating the need for manual user intervention in the connection process
2Extent of automation
If Wi-Fi Protected Setup (WPS) manner is used, then automatic network name and security key setting is achieved, but function keys or PIN codes are required and multiple operations are still needed
Solution Approach 1:
The patent extends self-service by enabling the terminal to automatically query, select, and connect to WLAN access points using pre-stored information without requiring WPS function keys, PIN codes, or multiple manual operations. The system autonomously completes the entire connection process including authentication
3Speed
If terminal collects wireless access point information in advance, then connection speed improves, but user still needs to manually select specific access point from displayed list
Solution Approach 1:
The patent applies self-service by implementing automatic selection logic that eliminates manual user intervention. The terminal autonomously queries available access points, compares them against pre-stored information, selects the most appropriate match, and initiates connection automatically, maintaining fast connection speed while removing the manual selection step

AI summary
A wireless local area network (WLAN) access method includes sending, by a terminal, a request for querying an available wireless access point to a server. The method further includes sending, by the server according to the query request, obtained information about the available wireless access point. The method further includes receiving, by the terminal, wireless access point information returned by the server, and determining a specific wireless access point from the received wireless access point information. The method further includes sending, by the terminal, an authentication information request of the specific wireless access point to the server. The method further includes when receiving the request, sending, by the server, authentication information corresponding to the specific wireless access point to the terminal, where the authentication information is used to connect the terminal to the specific wireless access point.
