Wi-Fi Direct Action Frames for Pre-Connection App Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices struggle to allow users to readily use desired applications before and after wireless connection establishment, as conventional techniques do not facilitate seamless integration and designation of applications during the connection process.
Innovation Solution
The wireless communication device incorporates information about its role into an action frame specified in the IEEE 802.11 specification and transmits it, allowing for inter-device communication using Wi-Fi Direct, enabling the designation of applications before and after connection establishment, and includes features like protocol switching and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication devices use conventional connection establishment methods, then connections can be maintained among devices in the same group, but users cannot readily use desired applications before and after connection establishment
Solution Approach 1:
The patent applies preliminary action by designating applications during the connection establishment process itself. The transmitting unit incorporates application designation information into action frames exchanged during connection setup, allowing applications to be predetermined before actual data transmission begins. This eliminates the need for separate application selection steps after connection is established.
2Adaptability or versatility
If wireless communication devices exchange role information during connection establishment, then application designation is facilitated, but data communication overhead increases
Solution Approach 1:
The patent merges role information exchange and application designation into a single integrated process. The transmitting unit combines role information (source/sink identification) with application designation information in the same action frames during connection establishment. This consolidation allows multiple functions to be achieved without proportionally increasing communication overhead.
Solution Approach 2:
The action frames used for role information exchange serve multiple functions simultaneously: they establish device roles (source/sink), designate applications for use, and confirm connection parameters. This multi-functionality reduces the need for separate communication exchanges for each purpose.
3Adaptability or versatility
If wireless communication devices maintain multiple connections simultaneously, then connectivity is improved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by designating which applications will run on which connections during the connection establishment phase. This allows the system to proactively manage resource allocation and power consumption by predetermined application-connection mappings, avoiding the need for dynamic resource management that would increase power usage during operation.
