Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently providing mirroring services between electronic devices without traditional network infrastructure or GPS signals, particularly in dense Wi-Fi environments, and there is a need for improved methods to facilitate device-to-device communication and authentication for seamless mirroring services.
Innovation Solution
The method employs Wi-Fi Aware communication to enable device discovery and authentication, allowing electronic devices to switch from Wi-Fi Direct to Wi-Fi Aware interfaces for efficient mirroring services, using protocols like Miracast over Aware, and incorporates Bluetooth Low Energy (BLE) triggered methods to optimize device discovery and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Wi-Fi Direct interface is used for device discovery and connection, then device-to-device communication can be established without traditional network infrastructure, but device discovery efficiency deteriorates in dense Wi-Fi environments
Solution Approach 1:
The patent introduces Wi-Fi Aware as an intermediary layer between devices. The Wi-Fi Aware interface acts as a mediator that enables efficient device discovery through structured announcement and listening procedures, while Wi-Fi Direct serves as the backend communication channel. This resolves the contradiction by using Wi-Fi Aware's organized discovery mechanism to overcome the inefficiency of Wi-Fi Direct's ad-hoc discovery in dense environments.
Solution Approach 2:
The patent segments the device discovery and connection process into two distinct phases: discovery phase using Wi-Fi Aware interface for efficient device annunciation and listening, and connection phase using Wi-Fi Direct interface for actual data transmission. This segmentation allows each protocol to optimize its strength - Wi-Fi Aware for discovery efficiency and Wi-Fi Direct for reliable communication.
2Ease of operation
If Miracast protocol is used for mirroring service, then seamless screen mirroring can be achieved between devices, but authentication complexity increases
Solution Approach 1:
The patent implements preliminary authentication actions through Wi-Fi Protected Setup (WPS) before establishing the Miracast connection. The authentication procedure is performed in advance during the Wi-Fi Aware discovery phase, including device identification, credential verification, and security key exchange. This preliminary authentication simplifies the overall process by resolving security concerns before the Miracast streaming begins, making the service seamless for users.
3Productivity
If interface switching from Wi-Fi Direct to Wi-Fi Aware is implemented, then device discovery efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal communication framework that supports both Wi-Fi Aware and Wi-Fi Direct interfaces through a common architecture. The system includes a unified message handling mechanism that can process messages from either interface, and an automatic interface selection logic that determines which interface to use based on the communication scenario. This multi-functionality reduces the perceived complexity by providing a single interface for developers while supporting multiple underlying protocols.

AI summary
A method of a first electronic device in a wireless communication system is provided. The method includes triggering a wireless fidelity aware (Wi-Fi Aware) interface, transmitting a first message including miracast-related information through Wi-Fi Aware to a second electronic device using the Wi-Fi Aware interface, receiving a second message corresponding to the first message from the second electronic device when the second electronic device triggers a Wi-Fi Aware interface based on the miracast-related information through Wi-Fi Aware, performing a mutual authentication procedure with the second electronic device, and transmitting Wi-Fi Aware-based data to the second electronic device.
