Communication Apparatus Concurrent Mode Channel Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses face challenges in simultaneously operating in both infrastructure mode and peer-to-peer (P2P) mode using a single wireless communication unit, leading to complications in channel assignment and role decision during wireless connections, resulting in failed connections when both devices declare equal intent to be a group owner.
Innovation Solution
A communication apparatus with a determination unit to assess concurrent operation in both modes and a control unit to manage the role decision by adjusting the Owner Intent, allowing it to operate as a service provider in the P2P mode, ensuring proper channel assignment and role determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication apparatus operates as a client in the P2P mode prior to communication in the infrastructure mode, then the apparatus can establish P2P connection, but the partner apparatus may be assigned a channel different from that used in the P2P mode, causing simultaneous communication operations to fail
Solution Approach 1:
The communication apparatus performs channel assignment in the P2P mode before establishing infrastructure mode communication. By pre-assigning a specific channel for P2P operations and storing this channel information, the apparatus ensures that when infrastructure mode communication is subsequently established, the P2P channel remains consistent and unchanged, enabling reliable simultaneous operations in both modes
Solution Approach 2:
The channel information acts as an intermediary element that bridges the P2P mode and infrastructure mode operations. The apparatus stores the P2P channel information and uses it as a reference to maintain channel consistency across both communication modes, preventing channel conflicts and enabling reliable simultaneous communication
2Adaptability or versatility
If one communication apparatus operates in both infrastructure mode and P2P mode simultaneously using one wireless chip, then the apparatus can perform multiple communication operations, but the system configuration becomes complicated with hardware and software arrangements
Solution Approach 1:
The single wireless communication unit is designed to perform multiple functions by supporting both infrastructure mode and P2P mode operations. The apparatus implements a unified channel management mechanism that allows the same wireless chip to handle different communication modes without requiring separate hardware components, thereby maintaining simplicity while achieving multi-functionality
Solution Approach 2:
The apparatus manages different communication modes by changing operational parameters such as channel assignments and communication protocols rather than requiring different hardware configurations. By dynamically adjusting these parameters based on the active communication mode, the system maintains simplicity while supporting concurrent operations in both infrastructure and P2P modes
3Ease of operation
If respective communication apparatuses declare the equal Owner Intents for deciding a group owner, then the apparatuses can express equal willingness to provide service, but role decision cannot be made, thereby disabling wireless connection
Solution Approach 1:
When both apparatuses declare equal Owner Intents, the system introduces an asymmetric tie-breaking mechanism based on apparatus identifiers. By comparing the identifiers of the two apparatuses, the system can deterministically select one as the group owner and the other as the client, ensuring that role decision is always made even when service provision willingness is equal, thus enabling wireless connection to proceed

AI summary
The following processing is executed by a communication apparatus capable of performing wireless communication in a first communication mode in which communication is performed via an access point and a second communication mode in which communication is performed with a communication partner apparatus in a peer-to-peer mode. If communicating with the communication partner apparatus in the second communication mode, it is determined whether to concurrently execute operations in the first communication mode and the second communication mode. If it is determined to concurrently execute the operations in the first communication mode and the second communication mode, it is controlled to operate as a service providing source which provides a service in the second communication mode.
