Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wireless LAN connection methods are used, then infrastructure access points are required for device connection, but this increases system complexity and reduces direct device-to-device communication capability
Solution Approach 1:
The patent uses BLE (Bluetooth Low Energy) as an intermediary communication channel to establish initial contact and exchange connection information between wireless devices. This intermediary approach enables devices to discover and connect to each other directly without requiring traditional Wi-Fi infrastructure access points, thereby reducing system complexity while maintaining adaptability for direct device-to-device communication.
2Speed
If traditional Wi-Fi direct connection methods are used, then connection establishment time is extended, but using BLE intermediary reduces connection speed
Solution Approach 1:
The patent performs preliminary actions by using BLE to establish initial device discovery and exchange connection parameters before the actual Wi-Fi direct connection is formed. This preliminary exchange of information through BLE accelerates the subsequent Wi-Fi connection establishment process, as devices already have mutual recognition and basic connection parameters when transitioning to the higher-speed Wi-Fi direct mode.
3Reliability
If more authentication data is exchanged during connection establishment, then connection security is improved, but this increases device complexity and power consumption
Solution Approach 1:
The patent segments the authentication and data exchange process into two distinct phases: an initial BLE phase for basic device identification and capability exchange, followed by a Wi-Fi direct phase for more comprehensive authentication and data transfer. This segmentation allows security measures to be distributed across different communication protocols, maintaining strong security while managing power consumption by using the lower-power BLE mode for initial interactions.

AI summary
A method by which a first wireless device performs a wireless connection in a wireless LAN system, according to one embodiment, comprises the steps of: receiving an advertising packet from a second wireless device through a primary channel, wherein the advertising packet includes first information for specifying a Wi-Fi service for the advertising packet and second information linked to the existence of additional data, and the first information is set as a first value linked to a DPP procedure or a second value linked to a NAN procedure; establishing a BLE-based connection with the second wireless device in order to receive the additional data; transmitting, to a second wireless terminal, a request packet for requesting additional data; and receiving, from the second wireless device, a response packet, including the additional data, as a response to the request packet, wherein the additional data is associated with DPP bootstrap URI information of the second wireless device.
