Wireless Communication Apparatus Reconnection via Pre-stored Channel Info
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems that simultaneously use multiple wireless communication methods, disconnecting some wireless connections can prevent the apparatus from restarting these connections, especially when using a common channel.
Innovation Solution
A communicating apparatus is designed with two communication units that can operate using different wireless communication methods. The second communication unit searches for an external apparatus using a wireless channel already in use by the first communication unit and reconnects to it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common channel is used for both infrastructure mode and P2P wireless communication, then device complexity is reduced, but reliability deteriorates when connections are disconnected
Solution Approach 1:
The patent applies preliminary action by having the wireless communication unit remember the channel information from previous P2P connections before disconnection occurs. When disconnection happens, the unit uses this pre-stored channel information to initiate reconnection, eliminating the need to search for available channels from scratch and ensuring reliable restart of wireless connections.
2Ease of operation
If the self apparatus serves as a client in infrastructure mode, then the access point decides the channel, but the self apparatus loses the ability to decide channel upon disconnection
Solution Approach 1:
The patent applies self-service by enabling the wireless communication unit to autonomously determine the channel for reconnection based on pre-stored channel information. When disconnected, the unit independently uses the remembered channel to initiate reconnection without requiring the access point to re-assign channels, thereby maintaining both ease of operation and adaptability.

AI summary
A communication apparatus performs a first communication processing to a communication partner apparatus based on a Bluetooth standard, establishes a wireless LAN connection based on an infrastructure mode between the communication apparatus and an external access point, and establishes a direct wireless LAN connection between the communication apparatus and the communication partner apparatus, wherein the direct wireless LAN connection is established without the external access point. The communication apparatus also concurrently performs the wireless LAN connection and the direct wireless LAN connection with each other, and searches the external access point in a state the direct wireless LAN connection is maintained, in a case where the wireless LAN connection is disconnected, wherein the external access point is external to the communication apparatus and is external to the communication partner apparatus.
