Dual Wi-Fi Connection Handover for Communication Failure Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices fail to notify users when wireless communication becomes inexecutable due to changes in network connectivity, requiring manual intervention to re-establish connections.
Innovation Solution
The communication device and terminal device establish multiple wireless connections using different Wi-Fi schemes, allowing the device to send disablement information via a secondary connection when the primary connection fails, enabling the terminal to notify the user and facilitate automatic reconnection through alternative methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single wireless connection is used for communication, then the device complexity is low, but the reliability of communication is reduced when the connection fails
Solution Approach 1:
The patent combines multiple wireless connection schemes (Wi-Fi Direct and infrastructure mode) within a single communication device, allowing the device to maintain communication through alternative paths when one connection fails, thereby improving reliability without requiring multiple separate devices
Solution Approach 2:
The patent changes the communication parameter by switching between different Wi-Fi schemes (direct connection vs. access point-mediated connection) based on connection status, enabling adaptive response to communication failures and improving overall system reliability
2Ease of operation
If manual intervention is required to re-establish connections, then the device complexity is low, but the ease of operation is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the communication device automatically detects connection failures, generates notification information, and sends it to the terminal device through the alternative wireless connection, eliminating the need for manual intervention and improving ease of operation
Solution Approach 2:
The system performs self-service by automatically detecting communication failures and notifying users through the alternative connection path without requiring user intervention to diagnose or report the issue, thereby improving ease of operation
3Reliability
If multiple wireless connections are established, then the reliability of communication is improved, but the device complexity increases
Solution Approach 1:
The patent uses an access point as an intermediary device that mediates communication between the communication device and terminal device, allowing the establishment of alternative communication paths without requiring complex direct peer-to-peer management between all devices

AI summary
A communication device may be configured to: establish a first wireless connection between the communication device and a first external device according to a first scheme, wherein the communication device is able to execute wireless communication with a terminal device by using the first wireless connection; establish a second wireless connection between the communication device and the terminal device according to a second scheme; and in a case where the communication device shifts to a state in which the communication device is unable to execute wireless communication with the terminal device by using the first wireless connection after both the first wireless connection and the second wireless connection have been established at the communication device, send disablement information to the terminal device by using the second wireless connection, wherein the disablement information indicates that the wireless communication using the first wireless connection is inexecutable.
