Solution Overview

Problem

Current Wi-Fi connection methods are inefficient when attempting to connect to a hidden access point (AP) with an incorrect Service Set Identifier (SSID), as they fail to identify the AP, leading to low connection efficiency.

Innovation Solution

A method that utilizes historical Wi-Fi connection data to determine relevant AP records with matching BSSID and encryption mode, and prioritizes SSID matching values to improve the chances of finding the target AP during a Wi-Fi scan, even if the initial SSID input is incorrect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional Wi-Fi connection method is used with incorrect SSID, then the target hidden AP cannot be identified, but connection efficiency is reduced

Engineering Contradiction:
ImproveAP identification accuracyVSAvoidconnection efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system performs preliminary actions by scanning for hidden APs using alternative identification methods (BSSID, encryption mode, signal strength) before attempting connection, and by pre-storing historical connection data for future reference when traditional SSID matching fails

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces intermediary parameters (BSSID, encryption mode, signal strength thresholds, historical connection records) that mediate between the incorrect SSID and the target hidden AP, enabling identification through multiple alternative criteria when primary SSID matching fails

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple scanning parameters are used to improve AP identification, then the complexity of the connection process increases

Engineering Contradiction:
ImproveAP identification reliabilityVSAvoidconnection process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the AP identification process into distinct stages: first attempting traditional SSID matching, then sequentially applying alternative criteria (BSSID matching, encryption mode verification, signal strength threshold filtering, historical record comparison) when initial methods fail, dividing the complex problem into manageable segments

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the scanning approach based on real-time conditions, switching between different identification methods depending on what information is available and what thresholds are met, making the process adaptive rather than statically complex

Inventive Principle:
Principle #15Dynamics

AI summary

A method for wireless fidelity, Wi-Fi, connection and related products are provided. The method includes the following. X parameters of a target access point, AP, are obtained, where the X parameters at least include a target service set identifier, SSID, of the target AP, and X is a positive integer. Wi-Fi scan is performed according to the X parameters. In response to unsuccessful finding of the target AP, according to current network environment information, M Wi-Fi connection records are determined from historical Wi-Fi connection data, where each of the M Wi-Fi connection records contains an AP previously connected, and M is a positive integer. Wi-Fi scan is performed according to the target SSID and SSIDs in the M Wi-Fi connection records. According to implementations of the present disclosure, efficiency of connecting to a hidden AP can be improved in the case of inputting a wrong SSID.
