Solution Overview

Problem

Existing wireless network registration methods are insecure and require user intervention, leading to vulnerabilities and user frustration, especially in unsecured WLAN environments.

Innovation Solution

A method for wireless terminals to register with external networks using lower-level communication layers, such as the MAC sub-layer, to exchange registration information without relying on IP-based communications, thereby reducing security vulnerabilities and user involvement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If unsecure high-level communications (IP/HTTP) are used for wireless terminal registration, then ease of operation and compatibility are improved, but security and vulnerability to malicious attacks deteriorate

Engineering Contradiction:
Improveease of registrationVSAvoidsecurity vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical/IP-level registration system with a MAC-layer authentication mechanism. Instead of using HTTP/IP communications for registration, the system uses MAC address-based authentication at the data link layer, eliminating the vulnerability chain while maintaining operational simplicity through automatic MAC-based identification.

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

Solution Approach 2:

The patent introduces a MAC address as an intermediary authentication token between the wireless terminal and external network. This MAC address serves as a secure mediator that enables registration without exposing higher-level communication protocols to attack, thus resolving the security vulnerability while preserving ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If unsecure registration modes are used, then device complexity and configuration requirements are reduced, but reliability and resistance to malicious activity deteriorate

Engineering Contradiction:
Improveconfiguration complexityVSAvoidregistration reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent implements self-service registration where the wireless terminal automatically uses its MAC address for authentication without requiring complex configuration. The system serves itself by automatically identifying and authenticating the terminal at the MAC layer, thereby maintaining low complexity while significantly improving registration reliability through secure MAC-based verification.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If MAC sub-layer registration is used instead of IP/HTTP, then security and vulnerability resistance are improved, but implementation complexity and protocol overhead increase

Engineering Contradiction:
Improvesecurity vulnerabilityVSAvoidimplementation complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent segments the registration process into distinct MAC-layer authentication and subsequent network access phases. By isolating the security-critical authentication at the MAC sub-layer and separating it from higher-level IP/HTTP operations, the system achieves enhanced security without proportionally increasing overall implementation complexity, as the MAC layer infrastructure is already present in wireless networks.

Inventive Principle:
Principle #1Segmentation

AI summary

A method to enhance connectivity for a user device in a wireless local area network, WLAN, configured in accordance with IEEE802.11, the method comprising: sending a registration request from the user device to a network entity; receiving a registration response at the user device in response to the registration request, indicating one or more registration plans associated with registering the user device with an external network in communication with the WLAN; selecting by the user device, a registration plan from the one or more registration plans; sending, by the user device, registration information associated with the user device to the network entity, the registration information being based on the selected registration plan; and receiving, by the user device from the network entity, a registration status indicating that the registration information has been determined by a server of the external network as valid for a successful registration.
