Solution Overview

Problem

Current Wi-Fi Simple Configuration methods, such as PIN-based and push-button configurations, are not convenient, leading to poor user experience in establishing wireless local area network connections, and there is a need for a more efficient and secure method to facilitate access.

Innovation Solution

An access point indicates support for automatic triggering of a wireless local area network connection through a beacon frame, allowing for automatic initiation of the Wi-Fi Simple Configuration registrar protocol between the access point and station, using pre-stored identifiers for identity confirmation and two-way authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual password entry is required for Wi-Fi access configuration, then security is improved, but user experience deteriorates due to complex operations and potential input errors

Engineering Contradiction:
ImprovesecurityVSAvoiduser experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service authentication where the access point automatically verifies the station's identity using pre-stored identifiers. The station autonomously triggers the registrar protocol and completes authentication without manual password entry, achieving both security through pre-configured credentials and ease of operation through automated processes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The access point pre-stores identifiers of authorized stations before actual connection attempts. This preliminary configuration of authentication credentials eliminates the need for real-time password entry while maintaining security, as the verification data is already prepared and stored in advance.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If automatic triggering of registrar protocol is implemented using pre-stored identifiers, then ease of operation is improved, but device complexity increases due to identifier storage and matching mechanisms

Engineering Contradiction:
Improveconfiguration simplicityVSAvoidaccess point structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The access point integrates multiple functions into a unified authentication mechanism. The same identifier storage and matching system serves both as a security credential repository and as the basis for automatic protocol triggering, eliminating the need for separate complex authentication modules while achieving automatic authentication.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If two-way authentication based on pre-stored identifiers is performed, then security is improved, but time consumption increases during the connection establishment process

Engineering Contradiction:
Improveauthentication securityVSAvoidconnection establishment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system skips the time-consuming manual password entry phase by directly proceeding with automated identifier-based authentication. The pre-stored identifiers enable rapid verification without requiring users to type or input complex passwords, significantly reducing the time required for connection establishment while maintaining security through two-way authentication.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

Embodiments of the present invention relate to a method for establishing a wireless local area network connection. An access point locally stores a station identifier, and the method specifically includes the following steps: The access point sends a beacon frame, where the beacon frame indicates that the access point supports automatic triggering of establishing a wireless local area network connection, so that a station triggers establishment of a wireless local area network connection after receiving the beacon frame; the access point receives a probe request frame sent by the station, where the probe request frame carries an identifier of the station, and the probe request frame is used to request to establish a wireless local area network connection; and when the locally stored station identifier includes the identifier of the station carried in the probe request frame, the access point establishes a wireless local area network connection to the station according to a registrar protocol of Wi-Fi Simple Configuration WSC. In the embodiments of the present invention, based on a STA identifier pre-stored by the access point, identity confirmation is completed by using an extended IE, so as to implement automatic triggering of a WSC process.
