Terminal Device Wireless Connection Protocol Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as the DPP scheme, struggle to establish connections between communication devices and external devices, especially when the devices do not support the predetermined Wi-Fi scheme rules.
Innovation Solution
A terminal device is equipped with computer-readable instructions that enable it to obtain related information from a communication device, and based on the type of device, send appropriate connection information to establish either a compliant or non-compliant wireless connection with an external device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal device uses a predetermined Wi-Fi scheme (DPP) to establish wireless connection, then connection security and protocol compliance are improved, but compatibility with devices incapable of executing the predetermined rule deteriorates
Solution Approach 1:
The terminal device dynamically adjusts its communication protocol based on the capabilities of the external device. When DPP capability is detected, the terminal uses DPP protocol for secure connection establishment. When DPP capability is not available, the terminal automatically switches to alternative protocols, thereby adapting its behavior to maintain both security and compatibility across different device types.
Solution Approach 2:
The terminal device is designed with multi-functional communication capabilities, supporting both the predetermined DPP scheme and alternative communication protocols. This universal design allows the terminal to function effectively with both DPP-capable devices and non-DPP devices, resolving the contradiction between protocol compliance and device compatibility.
2Adaptability or versatility
If a terminal device supports multiple communication protocols to improve compatibility, then device adaptability is improved, but system complexity increases
Solution Approach 1:
The terminal device performs preliminary detection of the external device's communication capabilities during the initial connection phase. By determining DPP capability in advance, the terminal can select the appropriate protocol before establishing the connection, avoiding the need to manage multiple protocols simultaneously and reducing system complexity.
Solution Approach 2:
The terminal device acts as an intermediary that mediates between different communication protocols. It detects the external device type and automatically selects or translates between DPP protocol and alternative protocols, simplifying the overall system architecture by centralizing protocol management in the terminal rather than requiring complex multi-protocol support across all devices.

AI summary
A terminal device may, in a case where a first type of related information including a public key is obtained due to a first type of communication device outputting the first type of related information, send first connection information to the first type of communication device. The first type of communication device may be capable of executing a wireless communication complying with a predetermined rule of Wi-Fi scheme. The terminal device may, in a case where a second type of related information different from the first type of related information is obtained due to a second type of communication device outputting the second type of related information, send second connection information to the second type of communication device. The second type of communication device may be incapable of executing a wireless communication complying with the predetermined rule.
