Multi-Channel Connection Control via Backup Frequency Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing connections across multiple frequency channels due to interference, leading to potential failures in disconnection requests and inadequate control over concurrent connections.
Innovation Solution
A communication apparatus capable of establishing and maintaining concurrent connections across multiple frequency channels, using orthogonal frequency division multiple access (OFDMA) to manage connections and disconnections efficiently, ensuring reliable communication even in the presence of interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an AP transmits disconnection request signals via the second frequency channel, then the disconnection can be controlled, but interference may prevent successful transmission and control
Solution Approach 1:
The patent uses a first frequency channel as an intermediary to transmit disconnection request signals intended for the second frequency channel. When interference occurs in the second frequency channel, the AP can still communicate disconnection requests through the first frequency channel, which serves as a backup communication path and ensures reliable connection control despite interference in the target channel.
2Productivity
If an AP establishes connections in multiple frequency channels, then throughput is increased, but managing disconnections becomes more complex and error-prone
Solution Approach 1:
The patent implements a universal disconnection request transmission mechanism where the first frequency channel serves multiple functions: it acts as both a primary communication channel and a backup control channel. This multi-functionality allows the system to manage disconnections across multiple frequency channels through a single reliable path, reducing the complexity of managing disconnections in each individual channel while maintaining high throughput through concurrent multi-channel connections.

AI summary
In a case where a communication apparatus 102 communicates, via a first frequency channel, an establishment request for establishing a connection with a communication apparatus 103 via a second frequency channel different from the first frequency channel that complies with the same communication standard as a connection via the first frequency channel, or a disconnection request for disconnecting the connection, the communication apparatus 102 establishes or disconnects the connection with the communication apparatus 103 via the second frequency channel.
