Wireless Channel Matching for Concurrent Infrastructure and P2P Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face complexity in managing concurrent infrastructure and peer-to-peer modes, particularly in maintaining stable channel allocation when regenerating wireless networks, as they often rely on a common channel for both modes and do not effectively handle scenarios where the first wireless network is regenerated after the second has been established.
Innovation Solution
A communication apparatus is designed to concurrently perform first and second wireless communications, with a control unit that sets a second wireless channel for the second communication to match the first wireless channel used in the first communication, ensuring stable channel allocation and efficient reconnection processes across different modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common channel is used for both infrastructure mode and P2P mode when performing concurrent communication, then the apparatus arrangement and processing become simpler, but channel allocation stability deteriorates when networks are regenerated
Solution Approach 1:
The patent segments the channel allocation management into two independent parts: one for infrastructure mode and one for P2P mode. When a P2P group is formed, the system determines whether to use the same channel as the infrastructure mode or a different channel, rather than forcing a common channel for both modes. This segmentation allows independent optimization of each mode's channel allocation.
Solution Approach 2:
The patent implements dynamic channel selection that adapts based on the operational state. When the infrastructure mode network is regenerated, the system dynamically determines whether to reallocate the P2P channel, rather than using a fixed common channel approach. This dynamic adjustment maintains stability while avoiding unnecessary complexity.
2Ease of operation
If the same channel is used for both first wireless network and second wireless network, then channel management is simplified, but reconnection efficiency deteriorates when the first network is regenerated after the second network is established
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors the operational state of both networks and adjusts channel allocation accordingly. When the infrastructure mode network is regenerated, the system receives feedback about this state change and automatically determines whether to reallocate the P2P channel, ensuring efficient reconnection without requiring complex manual management.
Solution Approach 2:
The patent performs preliminary channel determination before network regeneration occurs. By proactively checking whether the infrastructure mode network has been regenerated and pre-determining the appropriate P2P channel allocation, the system avoids delays during reconnection and maintains high productivity without sacrificing operational simplicity.
3Reliability
If different channels are used for first wireless network and second wireless network, then channel allocation stability is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by making channel allocation decisions specific to each operational context. Rather than using a uniform approach for all P2P groups, the system evaluates the specific state of the infrastructure mode network and makes localized channel allocation decisions. This allows stable channel allocation without requiring complex global management mechanisms.

AI summary
A communication apparatus has a communication function that can concurrently perform first communication in which communication with a partner apparatus is performed via another apparatus that decides a wireless channel to be used in the wireless communication and second communication in which communication with the partner apparatus is performed not via another apparatus by the communication apparatus deciding the wireless channel. In a state in which the first communication and the second communication are concurrently performed, if a connection for the first communication is to be established while a connection for the second communication is established, a second wireless channel used for the second communication is set so as to match the second wireless channel with a first wireless channel to be used when the connection for the first communication is established.
