Mobile Device Wi-Fi Relay DNS Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often experience unstable Wi-Fi signals due to poor network coverage, leading to abnormal communication between wireless access points and electronic devices, which can result in slow or impossible network access.
Innovation Solution
A method and apparatus for configuring the DNS service of a mobile device by functioning as a Wi-Fi relay, detecting abnormal communication, identifying the network service provider, and dynamically configuring a DNS list to ensure normal network access without restarting the Wi-Fi service or reconfiguring the DNS service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a router is placed in a sitting room and a handset is placed in a bedroom, then the Wi-Fi signal strength becomes weak, but network access stability deteriorates
Solution Approach 1:
The mobile device acts as an intermediary relay node between the router and the electronic device. It receives data from the router via Wi-Fi and forwards it to the electronic device via Bluetooth, bridging the gap when direct Wi-Fi connection is weak or unavailable.
Solution Approach 2:
The patent replaces the Wi-Fi communication mechanism with Bluetooth communication for the segment between the relay device and the electronic device. This substitution allows communication in areas where Wi-Fi signal is weak or unavailable.
2Area of stationary object
If Wi-Fi relay is used to improve network coverage, then signal coverage area increases, but communication throughput decreases
Solution Approach 1:
The patent applies different communication protocols for different segments: Wi-Fi is used for the segment with good signal strength (relay device to router), while Bluetooth is used for the segment with weak signal (relay device to electronic device). This local optimization maintains overall throughput while extending coverage.
3Reliability
If DNS service is reconfigured to fix network abnormalities, then network access stability improves, but device operation complexity increases
Solution Approach 1:
The system automatically detects network abnormalities, identifies the appropriate DNS server based on the network service provider, and configures the DNS settings without user intervention. This self-service approach maintains stability while avoiding the complexity of manual configuration.
Solution Approach 2:
The system continuously monitors network communication state and automatically adjusts DNS configuration based on detected abnormalities. This feedback mechanism ensures network stability while eliminating the need for manual user intervention in DNS management.
