Electronic Apparatus AP Connection Change Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a station (STA) connected to an access point (AP) receives a request to change its connection destination AP, it may experience issues with data transmission or reception failure due to IP address changes, especially during printing or data processing, leading to incomplete data transfer.
Innovation Solution
An electronic apparatus with a receiving unit, processing unit, and control unit that manages the connection change process by sending a notification to the information terminal before disconnecting from the current AP, allowing for a smooth transition to a new AP, ensuring uninterrupted data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the connection destination AP is switched in response to a change request, then the data transmission efficiency is improved by avoiding congestion, but data transmission failure occurs due to IP address changes
Solution Approach 1:
The electronic apparatus notifies the information terminal before actually changing the connection destination AP. This preliminary notification allows the terminal to prepare for the upcoming connection change, ensuring that data transmission can continue smoothly without interruption despite the IP address change that will occur when connecting to the new AP.
2Productivity
If the connection destination AP is changed during data transmission, then network congestion is avoided, but data reception becomes incomplete
Solution Approach 1:
The electronic apparatus provides feedback to the information terminal by sending a notification before the connection change. This feedback mechanism ensures that the terminal is aware of the upcoming AP change and can adjust its data reception accordingly, preventing data loss and ensuring complete data transfer even though the connection destination changes during ongoing data transmission.

AI summary
An electronic apparatus includes a receiving unit that receives a change request from a currently connected AP to change a connection destination AP to connect to; a processing unit that communicates with an information terminal via the currently connected AP and perform a specific process including transmission or reception of data; and a control unit that, in response to reception of the change request in a first state in which part of data for the specific process has been received or transmitted through communication with the information terminal and reception or transmission of rest of the data has not been completed, performs control to transmit a notification to the information terminal to request execution of a detection process for detecting the electronic apparatus before a connection with the currently connected AP is disconnected, and to execute a connection destination change based on the change request after transmission of the notification.
