Gateway Predicting Device Activation Time for Network Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In apparatus co-operation network systems, the long activation time of consumer electronics can cause user anxiety and lead to erroneous operations or failures, especially when controlling devices outside the visible area, and existing solutions do not accurately predict activation times for devices in a sleep state.
Innovation Solution
A gateway apparatus that monitors messages on a network, determines the predicted activation time of target devices, and transmits a response message with this information, allowing stable co-operation by executing processes based on the predicted activation time, while also reducing power consumption by selectively activating devices.

Engineering Contradiction Analysis
1Use of energy by moving object
If apparatuses remain in sleep state to reduce power consumption, then energy efficiency is improved, but control responsiveness and user experience deteriorate due to long activation times
Solution Approach 1:
The gateway apparatus performs preliminary actions by monitoring messages in the sleep state network and determining predicted activation times in advance. When a discovery message is received, the gateway checks if the target apparatus is in sleep state, and if so, determines how long it will take to activate based on historical data or device characteristics. This allows the system to prepare control messages ahead of time and transmit them as soon as the apparatus wakes up, eliminating the user-perceivable delay while maintaining power savings.
2Reliability
If the gateway monitors and manages activation times, then control stability is improved, but system complexity increases
Solution Approach 1:
The gateway apparatus serves as an intermediary between the sleep state network and the active apparatus co-operation network. It monitors discovery messages, determines activation states, calculates predicted activation times, and manages message transmission timing. This intermediary role centralizes the complexity in the gateway rather than requiring complex logic in each apparatus, simplifying the overall system architecture while improving control stability through centralized management.

AI summary
A gateway apparatus for allowing a plurality of apparatuses on a first network to co-operate with each other includes: a message monitoring unit which monitors messages communicated on the first network, and detects an apparatus discovery message for discovering an apparatus that satisfies an arbitrary requirement; an activation state managing unit which checks whether at least one target apparatus among the apparatuses that satisfies the requirement indicated by the apparatus discovery message is in an activated state for communication on the first network; a predicted activation time determining unit which determines a predicted activation time predicted as required to activate the at least one target apparatus; and a proxy response unit which transmits, in proxy of the at least one target apparatus, a response message including information indicating the predicted activation time when the at least one target apparatus is not in an activated state.
