Gateway Handover Using Repeater Backup for ISP Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gateway backup schemes are not suitable for home environments as they require additional hardware and lack flexibility, restricting users to a single device for network access, especially when broadband quality is poor or fails.
Innovation Solution
A method and apparatus for gateway handover that monitors ISP communication states, selects a repeater with backup gateway function as a new gateway, and employs multiple handover modes (first to fourth modes) to seamlessly transition network traffic and configuration, allowing the gateway to restart and reconfigure without additional hardware, maintaining network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gateway backup schemes are applied, then reliability is improved, but device complexity increases due to additional hardware components
Solution Approach 1:
The patent makes ordinary home routers capable of serving dual purposes: as access points for network connection and as backup gateways for failover. By enabling the backup gateway function in existing routers without additional hardware, the system achieves gateway backup reliability while avoiding increased device complexity. The same router hardware performs both normal routing and backup gateway functions.
Solution Approach 2:
The system implements automatic gateway failover detection and switching without requiring user intervention or additional dedicated backup hardware. The backup gateway mechanism uses existing network components to self-monitor and self-switch when the primary gateway fails, eliminating the need for complex external backup systems while maintaining reliability.
2Device complexity
If a single main routing device is used, then device complexity is reduced, but adaptability deteriorates as users cannot switch between multiple access modes
Solution Approach 1:
The patent implements dynamic gateway switching capability where the system can automatically transition between primary and backup gateways based on real-time network conditions. This dynamic failover mechanism allows the network to adapt to different access modes and gateway states without requiring users to manually configure multiple static routing devices, thus maintaining simplicity while enhancing flexibility.
Solution Approach 2:
The system pre-configures backup gateway capabilities in ordinary routers before failures occur. By preparing the backup gateway function in advance within existing devices, the system enables flexible access mode switching without adding hardware complexity, as the backup capability is already embedded in the network infrastructure.
3Adaptability or versatility
If gateway handover is implemented, then adaptability is improved, but loss of time increases during the handover process
Solution Approach 1:
The patent performs preliminary configuration of backup gateway parameters and network settings before handover is needed. By pre-synchronizing network configuration information to potential backup gateways, the actual handover process requires minimal time for reconfiguration, thus reducing handover duration while maintaining the ability to switch between multiple gateways adaptively.
Solution Approach 2:
The system implements real-time monitoring and feedback mechanisms to detect gateway failures and trigger handover automatically. This feedback-driven approach minimizes handover time by immediately responding to gateway status changes and initiating the switching process without manual intervention or prolonged detection delays.
