Communication Device G/O State Transition via Connection Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems involving printers and mobile terminals, the process of shifting to a Group Owner (G/O) state in a Wi-Fi Direct (WFD) scheme is often wasted when the mobile terminal is not prepared to establish a wireless connection, leading to inefficiencies and increased processing load.
Innovation Solution
A communication device that shifts to a G/O state in a WFD scheme only after establishing a wireless connection with an external device and receiving specific information, and then establishes a second wireless connection to allow the external device to participate in the WFD network, thereby optimizing the use of the G/O state and reducing processing load.

Engineering Contradiction Analysis
1Reliability
If the printer shifts to G/O state immediately after sending wireless setting information, then the printer can create a WFD network, but the process is wasted if the mobile terminal is not prepared to establish the wireless connection
Solution Approach 1:
The mobile terminal performs preparation for establishing a wireless connection before the printer shifts to the G/O state. The terminal sends a connection establishment request to the printer in advance, and only after this request is received and processed does the printer transition to the G/O state. This preliminary action ensures that the G/O state transition is not wasted.
Solution Approach 2:
The system implements a feedback mechanism where the mobile terminal sends a connection establishment request to the printer, and the printer responds by transitioning to the G/O state only after receiving this request. This feedback loop ensures that the printer has confirmation that the terminal is ready before making the state transition.
2Productivity
If the printer shifts to G/O state without confirming terminal readiness, then the printer can initiate WFD network creation, but unnecessary processing load increases
Solution Approach 1:
The mobile terminal sends a connection establishment request to the printer before the printer shifts to the G/O state. This preliminary action allows the printer to confirm that the terminal is ready, avoiding unnecessary G/O state transitions and reducing processing load.
Solution Approach 2:
The mobile terminal actively initiates the connection establishment process by sending a request to the printer, rather than the printer continuously checking or attempting connections. This self-service approach reduces the printer's processing burden.

AI summary
A communication device may shift an operation state of the communication device from a specific state to a G/O state in a case where a first wireless connection via a first wireless interface is established with a first external device under a situation where the operation state of the communication device is the specific state and predetermined information is received from the first external device using the first wireless connection, and after the operation state of the communication device has shifted to the G/O state in response to receiving the predetermined information from the first external device, establish a second wireless connection via a second wireless interface with the first external device so as to cause the first external device to participate as a client in a first wireless network in which the communication device operates as a G/O.
