Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The establishment of wireless connections between electronic devices is hindered by poor Bluetooth connection performance and stability, leading to long link establishment delays and affecting user experience.
Innovation Solution
Establish a Wi-Fi Direct channel directly between electronic devices using the MAC address of a Wi-Fi interface obtained from a near field communication (NFC) tag, eliminating the need for a Bluetooth connection, and perform Wi-Fi parameter negotiation to optimize the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth connection is used to establish link between electronic devices, then connection can be established, but link establishment delay is long due to poor Bluetooth connection performance and stability
Solution Approach 1:
The patent extracts the Bluetooth connection step from the connection establishment process. Instead of requiring Bluetooth connection as a prerequisite, the system directly uses Wi-Fi interface MAC addresses obtained through NFC tags to establish Wi-Fi Direct connections, removing the problematic Bluetooth intermediary that caused delays and stability issues
Solution Approach 2:
The patent introduces NFC tags as a new intermediary for connection establishment. The NFC tag stores the Wi-Fi interface MAC address, allowing devices to quickly exchange connection information without relying on Bluetooth. This new mediator (NFC) replaces the old mediator (Bluetooth) that caused performance problems
2Productivity
If Bluetooth connection is used as prerequisite for Wi-Fi Direct connection, then connection can be established, but connection performance is degraded due to poor Bluetooth connection performance
Solution Approach 1:
The patent removes the Bluetooth connection prerequisite from the Wi-Fi Direct establishment process. By extracting this dependency, the system can directly establish Wi-Fi connections using MAC addresses from NFC tags, improving both connection speed and stability by eliminating the unstable Bluetooth layer
Solution Approach 2:
Instead of using Bluetooth to facilitate Wi-Fi connection (the conventional approach), the patent inverts the logic by using NFC to directly provide Wi-Fi connection information. This inversion allows the system to bypass Bluetooth entirely and establish more reliable Wi-Fi connections

AI summary
This application provides a connection establishment method and an electronic device, and relates to the field of terminal technologies, so that a link can be established between electronic devices directly by using a Wi-Fi network, thereby improving link establishment performance and improving user experience. The method includes: A first electronic device obtains a media access control MAC address of a wireless fidelity Wi-Fi interface that is preset in a near field communication NFC tag of a second electronic device, negotiates a radio frequency parameter with the second electronic device by using the MAC address, and implements establishment of a Wi-Fi Direct channel with the second electronic device by using a determined target radio frequency parameter.
