Server Communication Recovery via Terminal Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where communication between a server and a communication device is interrupted, the server is unable to receive operation information, leading to a delay in recovering communication and thus, in receiving essential data such as consumable levels from the device.
Innovation Solution
A system where the server sends execution instructions to a terminal device to retrieve and resend the most recent setting information for the communication device, enabling the device to restart communication by adjusting its network settings, allowing the server to resume receiving operation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server waits for automatic communication recovery, then system stability is maintained, but the time to resume receiving operation information increases
Solution Approach 1:
The server stores setting information in advance before communication interruption occurs. When communication is restored, the terminal device can immediately use this pre-stored setting information to re-establish communication without waiting for manual intervention or lengthy diagnostic procedures, thus reducing the time loss while maintaining system reliability
Solution Approach 2:
The terminal device acts as an intermediary between the server and the communication device. It receives and stores setting information from the server, and upon communication restoration, uses this information to facilitate rapid reconnection, thereby mediating the recovery process and reducing overall communication downtime
2Reliability
If the operator manually restores communication, then communication stability is ensured, but the complexity of the recovery process increases
Solution Approach 1:
The terminal device performs self-service by automatically obtaining setting information from the server and using it to restore communication with the communication device without requiring operator intervention. This automation reduces process complexity while ensuring reliable communication recovery
Solution Approach 2:
Setting information is prepared and stored in advance by the server before communication interruption occurs. This preliminary preparation eliminates the need for complex manual configuration during recovery, simplifying the overall process while maintaining reliability
Data Source
AI summary
A server may include: a processor; and a memory storing computer-readable instructions therein, wherein the computer-readable instructions, when executed by the processor, cause the server to: receive operation information of a communication device and setting information from the communication device repeatedly, the setting information indicating a setting for the communication device to communicate with the server; and in a case where the server is not capable of receiving the operation information and the setting information from the communication device, send an execution instruction for executing a specific process to a terminal device being different from the communication device, the specific process including the terminal device receiving, from the server, first setting information which the server most recently received from the communication device, and sending the first setting information to the communication device.
