Communication Device Role Control for Wi-Fi Direct Service Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication devices face challenges in ensuring that wireless layer connection control is appropriate for service execution in the application layer, as connection control for the wireless layer is independent of service control, leading to inappropriate wireless layer functions operating during service execution.
Innovation Solution
A communication device is configured with specific software function blocks, including a GO Negotiation control unit and service discovery control unit, to determine and manage the roles of communication devices as either wireless LAN access points or stations based on the Wi-Fi Direct protocol, ensuring appropriate connection control for service execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection control for wireless layer is made independent of service control, then device complexity is reduced and ease of operation is improved, but inappropriate wireless layer functions may operate during service execution
Solution Approach 1:
The system establishes feedback mechanisms where service control information is transmitted to wireless layer control, and connection status is monitored and reported back. This allows the wireless layer to adjust its operation based on service requirements, ensuring appropriate function execution while maintaining automated control.
Solution Approach 2:
The patent merges previously independent wireless layer control and service control into an integrated control system. The service control unit and wireless layer control unit communicate and coordinate, combining their functions to ensure that wireless connection operations align with service execution requirements, thereby resolving the contradiction between automation and reliability.
2Ease of operation
If service discovery function is added to Wi-Fi Direct, then user convenience is improved, but device complexity and processing time increase
Solution Approach 1:
The service discovery function performs service information acquisition in advance during the connection establishment process. By discovering services before full connection is completed, the system prepares service configuration data ahead of time, reducing the overall time required for service execution while providing users with service information early in the process.
Solution Approach 2:
The patent introduces an action frame as an intermediary mechanism for service discovery communication. This intermediary structure allows efficient exchange of service information between devices during connection setup, reducing processing overhead and time consumption compared to traditional service discovery methods.

AI summary
An object is to perform connection control for a wireless layer appropriate for service execution in an application layer. A communication device determines to operate as an access point when serving as a device that provides a service in an application layer, whereas the communication device operates as a station when serving as a device that receives a service in the application layer.
