Solution Overview

Problem

Existing wireless broadband access technologies are vulnerable to unauthorized use due to security limitations, leading to economic losses for valid users as invalid terminals can exploit 3G/4G networks without traffic limits, unlike traditional WiFi networks which are charged based on usage.

Innovation Solution

A terminal access method and system that initiates dual verification processes - terminal identity verification and gateway identity verification - using encryption keys derived from IP and MAC addresses, ensuring only valid terminals access the wireless broadband network through a secure WiFi connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If WiFi identity verification is implemented, then network security is improved, but access complexity increases

Engineering Contradiction:
Improvenetwork securityVSAvoidaccess complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary identity verification before allowing network access. The terminal and gateway exchange verification requests and responses prior to establishing network connectivity, ensuring security credentials are validated in advance. This prevents unauthorized access while maintaining a structured access process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an identity verification mechanism as an intermediary layer between the terminal and network access. The verification system mediates the connection process by validating identities through exchanged credentials, acting as a security gatekeeper without requiring complex user intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If dual verification process is implemented, then unauthorized access prevention is improved, but authentication time increases

Engineering Contradiction:
Improveunauthorized accessVSAvoidauthentication time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent performs identity verification as a preliminary step before network access is granted. Both terminal and gateway identities are validated in advance through structured verification requests and responses, preventing unauthorized access before it can occur. This upfront verification reduces the need for later security interventions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where the gateway responds to terminal verification requests with acceptance or rejection decisions. This structured feedback loop allows for efficient authentication by providing clear validation results, reducing unnecessary delays in the access process.

Inventive Principle:
Principle #23Feedback

AI summary

The present disclosure discloses a terminal access method, system and device, and a computer storage medium. The method comprises: after establishing an WiFi connection with a wireless gateway, a terminal sends a terminal identity verification request and a gateway identity verification request to the wireless gateway; and after confirming that the terminal identity verification and gateway identity verification succeed, accesses to a wireless broadband network through the WiFi connection.
