Innovation Solution
A communication system that includes a first interface for Wi-Fi communication and a second interface for Bluetooth Low Energy communication, where the Bluetooth interface broadcasts a trigger signal to initiate a Wi-Fi connection request, allowing devices to form a wireless network using the Wi-Fi interface, thereby enabling efficient data transfer while maintaining security and reducing processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Bluetooth Low Energy is used for initial device discovery and connection initiation, then power consumption is reduced and device compatibility is improved, but a Bluetooth logical link must be established which increases processing load
Solution Approach 1:
The patent extracts the essential function of device discovery from the Bluetooth protocol stack by using simplified broadcast trigger signals that carry only necessary connection information (SSID, password) without requiring full Bluetooth logical link establishment. This separates the low-power discovery function from the complex connection management, reducing processing load while maintaining energy efficiency.
Solution Approach 2:
The system performs preliminary action by having the first communication apparatus broadcast trigger signals containing Wi-Fi connection information before actual Wi-Fi connection establishment. This allows the second apparatus to prepare connection parameters in advance, reducing the processing load during the actual connection phase and enabling faster network establishment.
2Speed
If Wi-Fi interface is activated for high-speed data transfer, then data transfer speed is improved, but network security risks increase due to broader access requirements
Solution Approach 1:
The patent introduces Bluetooth trigger signal broadcasting as an intermediary mechanism between device discovery and Wi-Fi connection establishment. This intermediary layer allows devices to authenticate and exchange connection credentials securely before activating the Wi-Fi interface, creating a security gate that controls access to the high-speed Wi-Fi network while maintaining security protocols.
Solution Approach 2:
The system performs preliminary security verification through Bluetooth trigger signal exchange before activating the Wi-Fi interface. Connection information including authentication credentials is shared in advance through the low-power Bluetooth channel, ensuring that only authenticated devices can initiate Wi-Fi connections, thereby reducing security risks associated with broader Wi-Fi access.
3Reliability
If Bluetooth logical link establishment is performed for secure communication, then communication security is improved, but processing load and connection time increase
Solution Approach 1:
The patent extracts only the essential security verification function from the complete Bluetooth logical link establishment process. Instead of performing full Bluetooth pairing and link management, the system uses simplified trigger signal broadcasting that carries authenticated connection information, maintaining communication security while dramatically reducing connection time and processing requirements.
Solution Approach 2:
Security verification is performed in advance through the Bluetooth trigger signal exchange mechanism. Connection credentials and authentication information are verified before Wi-Fi connection initiation, allowing the actual Wi-Fi connection to proceed quickly without repeated security checks, thus reducing overall connection time while maintaining security standards.

AI summary
A first communication apparatus may repeat a broadcast transmission of a trigger signal via a second interface, which is a signal to be used by a second communication apparatus as a trigger for sending a wireless connection request to the first communication apparatus. The wireless connection request may be for forming a first wireless network to which both the first communication apparatus and the second communication apparatus belong. The first wireless network may be a network for performing a wireless communication via a first interface. The first communication apparatus may receive the wireless connection request via the first interface from the second communication apparatus which has received the trigger signal, and establish a first wireless connection via the first interface with the second communication apparatus so as to form the first wireless network.
