Network Apparatus Wake-Up State Notification and Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network systems, such as those using Wake-on-LAN (WOL), lack the ability for terminal apparatuses to determine the state of image forming apparatuses during wake-up processing, leading to uncertainty and potential unauthorized wake-up instructions, which can result in inefficiencies and security concerns.
Innovation Solution
A network system that includes a terminal apparatus and a network apparatus with a wake-up instruction receiving unit, a wake-up control unit, and a state transmitting unit, allowing the terminal apparatus to receive and display the state of wake-up processing, including notifications of completion, authorization, and estimated time, thereby enabling timely and secure wake-up management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal apparatus waits for state information indicating image-formable state to be received, then it can determine wake-up completion, but the user experience deteriorates due to uncertainty and delayed awareness during the wake-up process
Solution Approach 1:
The network apparatus transmits state information notifications to the terminal apparatus at multiple stages of wake-up processing (starting, in-progress, completion). This feedback mechanism allows the terminal apparatus to display real-time wake-up status to the user, eliminating uncertainty while maintaining reliable completion determination through the final completion notification.
2Adaptability or versatility
If no authorization limitation is imposed on wake-up instruction transmission, then any terminal apparatus can wake up the network apparatus, but security deteriorates due to potential unauthorized wake-up instructions
Solution Approach 1:
The network apparatus performs authorization determination before executing wake-up processing. It checks whether the transmitting apparatus has the right to issue wake-up instructions based on predetermined authorization information. This preliminary authorization check prevents unauthorized wake-up while maintaining system versatility for authorized devices.

AI summary
Provided is a network apparatus that has a function of receiving a wake-up instruction from a terminal apparatus over a network and thereby waking up, including a wake-up instruction receiving unit that receives the wake-up instruction, a wake-up control unit that performs wake-up processing in a case of receiving the wake-up instruction, and a state transmitting unit that transmits a state notification of the wake-up processing to the terminal apparatus in the case of receiving the wake-up instruction.
