Terminal Device LAN Connection Verification for Internet-Enabled Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for connecting a communication device to a Local Area Network (LAN) do not facilitate communication with a server on the Internet, limiting the functionality of devices like printers in establishing connections for internet-based services.
Innovation Solution
A terminal device equipped with a communication interface and processor executes instructions to attempt communication with an Internet server via a LAN, sending connection information to other devices and requesting them to attempt internet communication, allowing successful connection and output of result information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal device sends connection information to the communication device without verifying server accessibility, then the connection setup process is simplified, but the communication device cannot communicate with the server on the Internet
Solution Approach 1:
The terminal device performs a preliminary test communication with the server on the Internet before sending connection information to the communication device. This preliminary action verifies server accessibility in advance, ensuring that the connection information provided to the communication device is valid and will enable successful server communication.
Solution Approach 2:
The system implements feedback by having the terminal device test communication with the server and use this feedback information to determine whether to send connection information. The communication device also provides feedback by attempting to communicate with the server after receiving connection information, allowing the system to verify whether the connection setup was successful.
2Productivity
If the terminal device always sends connection information to the communication device, then the connection setup is faster, but connection failures occur when the server is inaccessible
Solution Approach 1:
The terminal device performs a preliminary test communication with the server before providing connection information to the communication device. This preliminary verification ensures that connection information is only sent when the server is accessible, preventing futile connection attempts and improving overall connection success rates while maintaining efficient setup speed.
3Reliability
If the communication device attempts to communicate with the server after receiving connection information, then server accessibility is verified, but additional communication steps are required
Solution Approach 1:
The communication device autonomously attempts to communicate with the server on the Internet after receiving connection information from the terminal device. This self-service verification allows the communication device to independently confirm server accessibility without requiring manual intervention or complex configuration steps, simplifying the overall process despite the additional verification step.

AI summary
A terminal device may execute a first attempt process in which the terminal device attempts to communicate with a server on the Internet via a communication interface by using a specific LAN to which the terminal device is currently connected; and in a case where the attempt to communicate with the server is successful in the first attempt process, send connection information to a communication device different from the terminal device, the connection information being for connecting the communication device to the specific LAN, wherein in a case where a specific condition is fulfilled, the connection information is not sent to the communication device, the specific condition including a condition that the attempt to communicate with the server fails in the first attempt process.
