Wireless Communication Device Dynamic Role Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication protocols, such as the Device Provisioning Protocol (DPP) scheme, face challenges in dynamically determining the role of a communication device based on its connection status with access points, leading to inefficient establishment of wireless connections.
Innovation Solution
A communication device equipped with a wireless interface and a controller that determines its role based on connection status with access points, sending appropriate authentication responses and wireless setting information to establish either a role as a Configurator or Enrollee, enabling it to adapt its operation for establishing wireless connections accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a device uses fixed role assignment in wireless connection establishment, then the connection process is simple, but the adaptability to different connection scenarios is poor
Solution Approach 1:
The patent implements dynamic role assignment where the device automatically determines its role (Configurator or Enrollee) based on its current connection status with access points. The controller monitors whether the device is connected to an access point and dynamically assigns the appropriate role, enabling the device to adapt to different wireless connection scenarios without manual configuration.
2Adaptability or versatility
If a device automatically determines its role based on connection status, then the adaptability improves, but the authentication process becomes more complex
Solution Approach 1:
The device performs self-determination of its role based on its own connection status with access points. The controller automatically checks whether the device is connected to an access point and assigns the appropriate role (Configurator if connected, Enrollee if not connected), eliminating the need for manual role assignment or complex authentication configurations.
3Productivity
If the device sends wireless setting information to establish connection, then the connection establishment is efficient, but the device must maintain multiple connection states
Solution Approach 1:
The patent applies different connection establishment procedures based on the device's local connection status. When connected to an access point, the device uses Configurator mode to send wireless setting information efficiently. When not connected, it uses Enrollee mode to receive settings. This localized approach optimizes the connection process for each specific state without requiring complex state management across all scenarios.

AI summary
A first communication device may execute an output control process of externally outputting output information, the output information obtained using a public key of the first communication device, receive an authentication request from a second communication device that has obtained the public key, send a first authentication response to the second communication device via a wireless interface in a case where it is determined that a wireless connection has been established between the first communication device and a first access point, the first authentication response including first role information indicating that the first communication device is to serve a first role which is a role of sending first wireless setting information to the second communication device, and send the first wireless setting information to the second communication device.
