Terminal Device Wireless Connection Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication protocols, such as DPP, face challenges in efficiently establishing wireless connections between communication devices and access points, particularly in scenarios where the terminal device is not already connected to an access point.
Innovation Solution
The proposed solution involves a terminal device with a wireless interface configured for Wi-Fi communication, which obtains a public key of a communication device and determines if it is already connected to an access point. Based on this determination, the terminal device sends appropriate connection information to establish a wireless connection either through an access point or directly with the communication device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device uses conventional DPP protocol to establish wireless connection, then the connection can be established through access point, but the terminal device must be pre-connected to the access point which limits flexibility
Solution Approach 1:
The patent implements dynamic connection establishment by detecting whether the terminal device is connected to an access point and selectively executing different connection processes. The controller dynamically adjusts the connection protocol based on real-time connection status, enabling flexible peer-to-peer or access point-mediated connections as needed.
Solution Approach 2:
The patent changes the connection mode parameter based on access point connection status. When no access point connection exists, the system switches to peer-to-peer mode using direct communication; when access point connection exists, it uses access point-mediated mode. This parameter change resolves the contradiction by adapting connectivity behavior to environmental conditions.
2Reliability
If the terminal device always establishes connection through access point, then network security is improved, but connection speed and efficiency deteriorate when access point is unavailable
Solution Approach 1:
The patent performs preliminary detection of access point connection status before initiating the connection establishment process. This preliminary action allows the system to prepare the appropriate connection method in advance, avoiding delays caused by failed access point connection attempts when peer-to-peer connection would be more efficient.
Solution Approach 2:
The system dynamically selects between secure access point-mediated connection and direct peer-to-peer connection based on real-time network conditions. This dynamic adaptation maintains reliability by using secure pathways when available while improving productivity by using direct connections when access points are unavailable.
3Adaptability or versatility
If the terminal device supports both access point-mediated connection and peer-to-peer connection, then connection flexibility is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent segments the connection establishment process into distinct phases: access point connection detection, authentication request transmission, and connection information exchange. Each phase is handled by specific control logic that activates based on detection results, reducing overall complexity through modular process design.
Solution Approach 2:
The access point serves as an intermediary that mediates between the terminal device and communication device when network security is prioritized. When no intermediary is available, the system directly connects the two devices. This intermediary mechanism provides a clear decision pathway that manages complexity while maintaining versatility.
4Reliability
If the terminal device performs authentication before connection establishment, then security is improved, but connection establishment time increases
Solution Approach 1:
The patent performs authentication requests as a preliminary action during the connection establishment process. The terminal device sends authentication requests containing public keys before final connection is established, ensuring security is verified in advance while minimizing overall connection time through efficient protocol design.

AI summary
A terminal device may determine whether the terminal device has been established a wireless connection with an access point. In a case where it is determined that the terminal device has been established the wireless connection with the access point, the terminal device may send first connection information to the communication device, the first connection information being for establishing a wireless connection between the communication device and the access point. In a case where it is determined that the terminal device has not been established the wireless connection with the access point, the terminal device may communicate second connection information with the communication device, the second connection information being for establishing a wireless connection between the terminal device and the communication device not via the access point.
