Wi-Fi Direct Device Discovery Merging for Duplicate Partner Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems using the Wi-Fi Direct standard, when a station discovers another station capable of using both conventional Probe Request and Service Discovery Frame methods, it treats the station as two separate devices, complicating user selection of a communication partner.
Innovation Solution
A communication apparatus and method that integrates both Probe Request and Service Discovery Frame procedures to efficiently identify and select a compatible communication partner, utilizing a partner apparatus determination unit to consolidate information from both methods and facilitate seamless connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both Probe Request and Service Discovery Frame methods are used to discover communication partners, then discovery capability is improved, but device selection complexity increases
Solution Approach 1:
The patent merges the results from Probe Request discovery and Service Discovery Frame discovery into a unified device list. When the same communication partner is discovered through both methods, the system consolidates the information and presents it as a single entry, eliminating duplicate listings and simplifying user selection while maintaining the benefits of both discovery approaches.
Solution Approach 2:
The patent implements a universal device list that can accommodate and unify results from multiple discovery methods (Probe Request and Service Discovery Frame). This multi-functional approach allows the system to handle different discovery protocols through a single interface, improving adaptability while maintaining simplicity in device selection.
2Productivity
If multiple discovery methods are employed, then partner finding efficiency is improved, but information management complexity increases
Solution Approach 1:
The patent combines information from multiple discovery methods into a single unified device list. By merging the results from Probe Request and Service Discovery Frame methods and eliminating duplicates, the system improves partner finding efficiency while managing information complexity through consolidation rather than separate management of multiple lists.
3Reliability
If a station is treated as separate devices when discovered through multiple methods, then discovery completeness is improved, but user experience deteriorates
Solution Approach 1:
The patent merges duplicate device entries that result from multi-method discovery into single unified entries. This ensures that all communication partners are discovered (maintaining completeness) while presenting them in a clean, non-redundant list that improves user experience by making device selection straightforward and intuitive.

AI summary
A communication apparatus that communicates a wireless frame compliant with a Wi-Fi Direct (WFD) standard, performs (S1002) 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 (S1003) 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 (S1004) 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 (S1006) 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.
