Electronic Apparatus AP Handover Control for Stable Network Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face issues when disconnecting from an access point (AP) due to unsuitable network reconnection controls, leading to potential network disconnection and loss of communication.
Innovation Solution
An electronic apparatus is configured to receive a change request for a new access point, store information about a recommended connection destination, and upon disconnection from the current AP, reconnects to the new access point based on this stored information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic apparatus changes the connection destination AP based on the AP change request, then the network communication efficiency is improved, but the connection stability deteriorates and may cause network disconnection
Solution Approach 1:
The electronic apparatus stores the BSSID of the recommended AP in advance upon receiving the AP change request, before actually changing the connection destination. This preliminary storage action ensures that if disconnection occurs, the apparatus can quickly reconnect using the pre-stored BSSID information, thus maintaining connection stability while still allowing for efficient AP switching when conditions are favorable.
2Reliability
If the electronic apparatus does not change the connection destination AP, then the connection stability is maintained, but the network communication efficiency deteriorates due to inability to utilize optimal AP
Solution Approach 1:
The apparatus prepares the BSSID of the recommended AP in advance by storing it when the AP change request is received. This allows the apparatus to maintain connection stability by not forcibly switching, while still having the optimal AP information ready for quick reconnection if needed, thus preserving the possibility of future efficient connection without compromising current stability.
3Loss of time
If the electronic apparatus automatically reconnects to the original AP after disconnection, then the reconnection speed is improved, but the risk of connecting to a suboptimal AP increases
Solution Approach 1:
Instead of storing only the original AP's BSSID, the apparatus stores the BSSID of the recommended AP (which was identified as optimal by the network) in advance. When reconnection is needed, the apparatus uses this pre-stored optimal BSSID, achieving both fast reconnection and connection to a high-quality AP, thus resolving the contradiction between reconnection speed and AP selection quality.

AI summary
An electronic apparatus includes a communication device unit that receives, from a first access point to which the electronic apparatus is currently connected, a change request of an access point serving as a connection destination and at least one memory storing a program and at least one processor that when executing the program stores, after receipt of the change request, information regarding a second access point that is a connection change destination recommended in the change request, performs control to not change the connection destination based on the received change request, and performs control, when the electronic apparatus is disconnected from the currently connected first access point, to connect to the second access point based on the stored information.
