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 lack efficient methods for designating and starting specific applications during inter-device communication.
Innovation Solution
The wireless communication device incorporates information about its role into an action frame specified in the IEEE 802.11 specification, allowing inter-device communication with another device using Wi-Fi Direct, and includes features like a transmitting unit to transmit this information, enabling seamless application designation and switching during P2P connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication devices establish connections before application designation, then connection stability is improved, but application switching and reconnection procedures increase complexity and time consumption
Solution Approach 1:
The patent applies preliminary action by incorporating application information into action frames during the connection establishment phase. This allows the receiving device to prepare application execution in advance, eliminating the need for separate application designation and reconnection procedures when switching applications, thus reducing time loss while maintaining connection stability
2Adaptability or versatility
If multiple applications are supported during wireless communication, then adaptability is improved, but device complexity and information processing overhead increase
Solution Approach 1:
The patent implements universality by designing a unified action frame structure that can carry information about multiple different applications (such as Wi-Fi Display, Wi-Fi P2P File Transfer, etc.). This single multi-functional frame structure allows devices to support multiple applications without requiring separate complex protocols for each application, thus improving adaptability while controlling device complexity
3Measurement precision
If role information is transmitted during inter-device communication, then application designation accuracy is improved, but communication overhead and data transmission volume increase
Solution Approach 1:
The patent applies merging by combining role information, application information, and communication control information into a single action frame structure. This consolidation transmits multiple types of information simultaneously using one standardized frame format, improving application designation accuracy through comprehensive information while minimizing communication overhead by avoiding multiple separate transmissions
