Hotspot Session Transfer Between Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for establishing communication links between client electronic devices and hotspot access points fail to effectively handle situations where the access point becomes unavailable, requiring multiple active access points and client devices to store information about other access points for reconnection, which is inefficient and unreliable.
Innovation Solution
A method and system that detect events such as access point unavailability and automatically transfer the hotspot session to a different electronic device, allowing seamless reconnection without the need for multiple active access points or client devices to store information about other access points, by monitoring powering, memory, and network states and sending a request for hotspot session transfer with necessary configuration details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple active access points are deployed and client devices store information about other access points for reconnection, then network availability is improved, but device complexity and information storage requirements increase
Solution Approach 1:
The system performs preliminary actions by establishing a standby access point before the host access point becomes unavailable. The standby access point is pre-configured with network credentials and client device information, so when the host access point fails, the standby can immediately take over without requiring client devices to search for or store alternative access point information.
Solution Approach 2:
The patent introduces a standby access point as an intermediary between the host access point and client devices. This intermediary maintains the network connection alive by taking over when the host fails, eliminating the need for client devices to directly manage multiple access point information or perform complex reconnection procedures.
2Adaptability or versatility
If client devices search for network credentials and preconfigured alternate access points after disconnection, then reconnection capability is improved, but connection time and reliability deteriorate when alternate access points are unavailable
Solution Approach 1:
The standby access point is pre-configured with all necessary network credentials, host access point information, and client device details before any failure occurs. This preliminary configuration enables immediate takeover without requiring client devices to perform time-consuming searches or credential verification procedures.
Solution Approach 2:
The system implements a monitoring mechanism that detects when the host access point becomes unavailable and automatically activates the standby access point. This feedback loop ensures seamless transition without requiring client devices to initiate reconnection searches, thereby reducing connection time and improving reliability.
3Reliability
If the host access point monitors powering, memory, and network states to detect transfer events, then session transfer reliability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The host access point monitors only critical parameters (powering state, memory state, network state) rather than all possible system states. This partial monitoring approach provides sufficient reliability for detecting when session transfer is needed while minimizing energy consumption compared to comprehensive system monitoring.
