Communication Apparatus Network Reconnection via Power Status Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication apparatuses experience delays in re-establishing network connections when moving from areas with to areas without network signal coverage, as they only perform network searches at the end of a sleep cycle, leading to increased waiting times for users and potential missed messages.
Innovation Solution
A communication apparatus with a detection unit that sends a trigger signal upon changes in power status, enabling the RF module to immediately search for network signals and reconnect, reducing the need to wait for the end of a sleep cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the RF module performs network search only at the end of each sleep cycle, then power consumption is reduced, but network reconnection delay increases
Solution Approach 1:
The system performs preliminary actions by detecting power status changes and proactively triggering network searches before the sleep cycle ends. When the detection unit senses that the communication apparatus is about to wake up or power status changes, it提前 activates the RF module to search for network signals, thus reducing reconnection delay without significantly increasing power consumption.
Solution Approach 2:
The patent makes the network search timing dynamic by adjusting the search trigger based on power status changes. Instead of a fixed periodic search at sleep cycle ends, the system dynamically determines when to initiate network searches based on actual power status transitions, optimizing the balance between power consumption and reconnection speed.
2Use of energy by moving object
If the communication apparatus waits for the end of the current sleep cycle before performing network search, then power consumption is minimized, but user convenience deteriorates
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring power status changes and using this information to trigger network searches. The detection unit provides feedback about power status transitions, which then triggers the RF module to perform network searches at optimal moments, improving user convenience while maintaining reasonable power consumption levels.
3Speed
If the RF module is activated immediately when network signals are regained, then network reconnection speed improves, but power consumption increases
Solution Approach 1:
The system performs preliminary detection of power status changes and prepares for network search in advance. When power status changes indicate the apparatus is waking up, the system提前 triggers the network search process, enabling faster reconnection without requiring continuous RF module activation, thus balancing speed and power consumption.

AI summary
A network search method for a communication apparatus connected to a network is disclosed. The method comprises the following steps. The communication apparatus enters a sleep mode when the communication apparatus loses signals from the network. Then, power status of the communication apparatus is detected. A trigger signal is automatically sent when a change in power status of the communication apparatus is found. Next, a radio frequency module is enabled to search for the signals from the network according to the trigger signal so as to reconnect to the network.
