Solution Overview

Problem

Users face the inconvenience of repeatedly entering account and password on a WEB authentication page when accessing a wireless local area network, leading to a complex and time-consuming authentication process.

Innovation Solution

A wireless local area network authentication method where a mobile terminal automatically obtains a local phone number and sends a dynamic password request to a network server, receiving a short message with a dynamic password, which is then used to automatically complete the WEB authentication process without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If WEB authentication is used for carrier charging, then the carrier can perform charging for WLAN usage, but the user needs to manually enter account and password each time, increasing operation complexity and time consumption

Engineering Contradiction:
Improvecarrier charging capabilityVSAvoidauthentication operation complexity
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The system enables self-service authentication by automatically obtaining credentials through SMS delivery. The terminal device autonomously completes the authentication process by receiving the dynamic password via SMS and submitting it to the authentication server without requiring manual user input, thus maintaining carrier charging capability while eliminating operational complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The SMS message serves as an intermediary carrier that automatically delivers the dynamic password from the authentication server to the terminal device. This intermediary mechanism bridges the gap between the server and user, enabling automatic credential delivery and eliminating the need for manual authentication operations

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If manual authentication is required each time, then security is maintained through user input, but time is wasted on repetitive operations

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication time consumption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary authentication by pre-generating and delivering the dynamic password to the terminal device via SMS before the actual WLAN connection is established. This preliminary action allows the authentication credentials to be ready in advance, enabling rapid automatic authentication without time-consuming manual operations while maintaining security through server-generated credentials

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manual mechanical input process (user typing account and password) is replaced by an automated electronic system that receives the dynamic password via SMS and automatically submits it for authentication. This substitution eliminates repetitive manual operations and time consumption while maintaining the security function through server-validated credentials

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If automatic authentication is implemented, then user experience is improved by eliminating manual input, but the system complexity increases with SMS integration

Engineering Contradiction:
Improveauthentication automationVSAvoidsystem architecture complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The existing SMS messaging infrastructure is leveraged for its multi-functionality, serving both as a communication channel and as the authentication credential delivery mechanism. By utilizing the already-deployed SMS system, the solution achieves automatic authentication without adding significant new infrastructure complexity, as SMS capability is universally available in mobile devices

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

AI summary

Embodiments of the present invention disclose a wireless local area network authentication method, including: automatically obtaining, by a mobile terminal, an access account and an access password; and automatically sending, by the mobile terminal, a WEB authentication request to a network server, where the WEB authentication request carries the access account and the access password. The embodiments of the present invention further disclose a corresponding mobile terminal. By applying the wireless local area network authentication method and the mobile terminal disclosed in the present invention, a mobile terminal can automatically complete WEB authentication of a wireless local area network, a user does not need to enter an account and a password, and a WEB authentication interface does not need to be displayed to the user either, thereby avoiding a complex and repetitive authentication operation and improving user experience.
