Wi-Fi Direct Device Discovery Deduplication for Easier Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems using the Wi-Fi Direct standard, there is a challenge in efficiently selecting a communication partner when multiple detection methods (Probe Request/Response and Service Discovery Frame) identify the same device as separate entities, complicating user choice.
Innovation Solution
A communication apparatus equipped with first and second detection units for Probe Request/Response and Service Discovery Frame, respectively, determines and outputs a single apparatus identity when detected by both methods, facilitating user selection.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple detection methods (Probe Request/Response and Service Discovery Frame) are used to search for partner apparatus, then the completeness of device discovery is improved, but the same apparatus may be detected as multiple separate devices, complicating user selection
Solution Approach 1:
The patent merges detection results from multiple detection methods (Probe Request/Response and Service Discovery Frame) by comparing device information such as MAC addresses and device names. When the same apparatus is detected through both methods, the system consolidates these detections into a single unified device entry, eliminating duplicates and simplifying the user selection interface while preserving complete device discovery capability
Solution Approach 2:
The system creates and compares information copies from different detection methods. By extracting key identifiers (MAC address, device name) from both Probe Request/Response and Service Discovery Frame detections and comparing these copied information sets, the system can identify identical devices detected through multiple channels and merge them appropriately

AI summary
A communication apparatus that communicates a wireless frame compliant with a Wi-Fi Direct (WFD) standard, performs a first detection of another communication apparatus according to a first method of searching for a partner apparatus for communication using a first wireless frame defined by the WFD standard, performs a second detection of another communication apparatus according to a second method of searching for the partner apparatus using a second wireless frame that is defined by the WFD standard and is not used in the first method, determines whether the same apparatus has been detected in the first detection and the second detection by analyzing the first wireless frame and the second wireless frame, outputs information indicating the apparatus as a single apparatus in a case where the same apparatus has been detected in the first detection and the second detection.
