Wireless Device Internet Redirection Detection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices experience disruptions and lack of awareness when switching between cellular base stations and hotspots due to internet access redirection, which can lead to improper functionality of applications and unawareness of authentication requirements by hotspots.
Innovation Solution
A method for a wireless device to automatically detect internet access redirection by sending requests to known non-redirection servers and comparing responses to determine discrepancies, using DNS and HTTP detection techniques to identify redirection types, and alerting the user or authenticating through a web browser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hotspots restrict internet access until authentication tasks are performed, then hotspots can control and manage network access, but wireless device applications experience interruptions and improper functionality
Solution Approach 1:
The patent performs preliminary detection of hotspot redirection by sending test requests to known non-redirection servers before the user becomes aware of the authentication requirement. This advance detection allows the system to prepare for potential redirection issues, maintaining application functionality by alerting users proactively rather than reactively when applications fail.
2Reliability
If hotspots redirect internet requests to authentication webpages, then hotspots can enforce authentication, but users become unaware of the switch between internet access services
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors internet requests and their responses to detect redirection. When redirection is detected, the system provides feedback to the user through alerts or notifications, informing them that they have been redirected to an authentication page. This maintains user awareness while still enforcing authentication requirements.
3Productivity
If wireless devices switch between cellular base stations and hotspots automatically, then internet access speed and cost are optimized, but users cannot distinguish between different internet access services
Solution Approach 1:
The patent introduces an intermediary detection layer that sits between the wireless device and the internet access services. This intermediary actively probes the network to identify whether the device is connected to a hotspot or cellular network, and whether redirection is occurring. It provides this information to the user, enabling them to understand which service they are using while maintaining the automatic switching benefits.
4Reliability
If DNS or HTTP forwarding is used for redirection, then hotspots can control access, but every wireless device application accessing the internet is interfered with
Solution Approach 1:
The patent extracts the detection function from the application layer and implements it at the network layer. By detecting redirection at the DNS or HTTP protocol level before applications make requests, the system can identify and handle redirection issues independently of individual applications. This prevents widespread application interference while maintaining access control, as the detection mechanism operates separately from application logic.

AI summary
The disclosed wireless device automatically detects the redirection of its internet access via a wireless hotspot network. The exemplary device algorithm provides the flexibility to detect either or both of DNS redirection and HTTP redirection, as well as to automatically accommodate such internet redirection. The proposed algorithm allows a wireless device user to be alerted and account for internet redirection when such internet redirection is automatically detected upon entering service via a hotspot. Alternatively, the wireless device may attempt to automatically meet the hotspot requirements and complete the internet access through the hotspot.
