Solution Overview

Problem

Configuring client devices to establish full data communication with external systems through wireless local area networks (WLANs) presents challenges, including accidental connections to unintended gateways, which can lead to decreased network performance and security risks.

Innovation Solution

The system verifies the client device's data connection to the intended gateway by providing a non-routable IP address and gateway identifier, allowing the client device to attempt data transmissions through both WLAN and external data communication channels, and comparing the received gateway identifier with a stored identifier to ensure correct connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If client devices automatically connect to available WLAN gateways, then ease of operation is improved, but reliability deteriorates due to accidental connections to unintended gateways

Engineering Contradiction:

Improveautomatic connectionVSAvoidconnection accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary verification actions before establishing full data communication. The client device receives verification data (gateway identifier and non-routable IP address) from an external trusted source before attempting connection, and then verifies the connection by comparing received gateway identifier with the verification data before allowing full communication.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by comparing the gateway identifier received during data transmission with the gateway identifier obtained from the external trusted source. This feedback mechanism confirms whether the client device is connected to the intended gateway, allowing the system to detect and prevent accidental connections to unintended gateways.

Inventive Principle:

Principle #23Feedback

2Reliability

If gateway identifier verification is implemented, then reliability is improved, but device complexity increases due to additional verification steps

Engineering Contradiction:

Improveconnection verificationVSAvoidverification process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The gateway identifier and non-routable IP address verification data are obtained from an external trusted source before the connection verification process begins. This preliminary action prepares the verification data in advance, simplifying the actual verification process by having all necessary comparison data ready before connection attempts.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An external trusted source acts as an intermediary that provides the gateway identifier and non-routable IP address to the client device before verification. This intermediary supplies pre-authenticated verification data, reducing the complexity of implementing verification logic within the client device itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Systems, methods, and apparatuses are described for verification of wireless network connection. A wireless local area network may comprise a client device and a gateway. A data connection, within the wireless local area network, between the client device and the gateway may be verified based on gateway identifiers provided to the client device via data communication channels internal and external the wireless local area network.
