Direct Wireless Communication Partner Identification and Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, such as those using Wi-Fi Direct, there is a risk of unintended devices being connected due to incorrect identification of communication partners, leading to data transmission errors where data is sent to the wrong device.
Innovation Solution
A communication apparatus with an identification unit to search for communication partners, a determining unit to assess if user confirmation is needed, a display unit to show a confirmation screen if needed, and a connection unit to establish or terminate connections based on user instructions, ensuring intended devices are connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If automatic partner identification is performed without user confirmation, then connection speed is improved, but connection reliability deteriorates due to potential misidentification
Solution Approach 1:
The system performs preliminary automatic identification of communication partners, then presents the identification results to the user for confirmation before final connection. This preliminary action allows the system to prepare connection information in advance while still enabling user verification, thus balancing speed and reliability.
Solution Approach 2:
The system provides feedback to the user by displaying identified communication partner information and seeking user confirmation. This feedback mechanism allows users to verify automatic identification results and correct potential errors, improving connection reliability while maintaining the efficiency of automatic identification.
2Reliability
If user confirmation is required for each connection, then connection reliability is improved, but operation complexity increases
Solution Approach 1:
The system applies user confirmation selectively rather than universally. For standard connection scenarios, automatic identification suffices. User confirmation is triggered only when identification results are ambiguous or when security policies require it, thus maintaining simplicity for common operations while ensuring reliability when needed.
3Productivity
If automatic connection is performed without display confirmation, then productivity is improved, but data transmission accuracy deteriorates
Solution Approach 1:
The display unit serves as an intermediary between the automatic identification system and the final connection action. It presents identification results to the user, allowing verification of the correct communication partner before data transmission begins, thus ensuring accuracy without significantly impacting productivity.

AI summary
A communication apparatus to execute a direct wireless communication includes an identification unit, a determining unit, a display unit, and a connection unit. The identification unit identifies, by performing search processing, one device as a communication partner of the direct wireless communication. The determining unit determines whether a user's instruction is needed to establish the direct wireless communication between the one identified device and the communication apparatus. The display unit displays, where a user's instruction is needed, an instruction screen allowing a user to instruct establishing the direct wireless communication. The connection unit performs, where the user has issued the instruction, connection processing to establish the direct wireless communication via the instruction screen. Where the determination unit has determined that the user's instruction is not needed, the connection unit performs the connection processing without the displaying unit displaying the instruction screen.
