Wireless Communication Apparatus Direct Connection Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication methods, such as IEEE 802.11 standard, require significant time to establish connections due to the need for scanning multiple channels, which is inefficient for devices consistently connected to the same access point, causing user frustration.
Innovation Solution
A communication apparatus that stores connection information for frequently connected access points, allowing for direct connection establishment without scanning, and includes features like priority settings and synchronization to enhance reliability and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive scan or active scan is performed to search for connection target stations on all channels, then the terminal can find available access points, but the connection establishment time becomes excessively long
Solution Approach 1:
The terminal performs scanning and connection information acquisition in advance, storing the BSSID and channel information of previously connected access points in memory. When connection is needed, the terminal directly uses the stored information to establish connection without performing full channel scanning, thus resolving the contradiction between reliable connection establishment and time consumption.
Solution Approach 2:
The terminal creates a copy of connection information (BSSID, channel) from previously scanned access points and stores it locally. This copied information is then used for rapid reconnection, avoiding the need to repeat the full scanning process while ensuring connection reliability to the same access point.
2Reliability
If the terminal scans all eleven channels to ensure it finds the correct access point, then connection reliability is maintained, but the process becomes unnecessarily complex and time-consuming for home networks
Solution Approach 1:
The terminal applies different connection strategies based on the local network environment. For home networks where the access point is fixed, the terminal uses stored BSSID and channel information for direct connection. For public wireless LANs where access points may change, the terminal performs full scanning. This localized adaptation resolves the contradiction between connection reliability and process complexity.
Solution Approach 2:
The terminal dynamically adjusts its connection establishment method based on whether connection information is available in storage and whether the current environment matches previously scanned environments. The system transitions between direct connection mode (using stored information) and scanning mode (full channel search), optimizing the balance between reliability and complexity based on real-time conditions.

AI summary
A first determination section determines, when an instruction for connection establishment is issued, whether or not connection information including target apparatus specifying information that uniquely specifies a predetermined target apparatus is stored in a first storage section. A first connection section performs, when the first determination section determines that the connection information is stored in the first storage section, a process for establishing a connection by wireless communication to the target apparatus that is specified based on the target apparatus specifying information stored in the first storage section.
