Remote Reboot via Power Supply Module for Halted Access Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadband access devices require on-site rebooting when halted, as software reset methods are ineffective, leading to reduced maintenance efficiency due to diverse device structures and challenging access locations.
Innovation Solution
A method and system where an office-end device monitors a user-end access device and sends a reboot command to initiate a power supply module for powering off and rebooting, utilizing a PON MAC chip to convert the command into a hardware reset signal, allowing remote control of the reboot process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software reset method is used to reboot a halted device, then the system can be reset remotely, but the method is invalid when the CPU small system is fully halted
Solution Approach 1:
The patent introduces a power supply module as an intermediary component that receives reboot commands from the CPU small system and executes power cycling. When the CPU small system is halted, the command routing module redirects the reboot command to the power supply module, which then cuts and restores power to the device, achieving remote reboot without requiring CPU small system operation.
Solution Approach 2:
The patent changes the operational parameter from software-based CPU control to hardware-based power control. By switching from a software reset mechanism (which fails when CPU is halted) to a power supply control mechanism (which operates independently of CPU state), the system achieves reliable remote reboot capability even when the CPU small system is fully halted.
2Ease of repair
If technical personnel power off and reboot devices at the site, then the device can be reset, but the maintenance efficiency is greatly reduced
Solution Approach 1:
The patent implements self-service by enabling automated remote reboot of devices without requiring technical personnel to physically visit the device location. The system allows centralized management of multiple devices through automatic command execution, eliminating the need for on-site intervention and significantly improving maintenance efficiency.
Solution Approach 2:
The patent creates a universal remote management system that can reboot diverse device types (optical network terminals, cable modems, set-top boxes) through a single centralized platform. The command routing module and power supply module work together to provide a unified reboot mechanism that adapts to different device structures and functions, eliminating the need for separate on-site operations for each device.
3Object-affected harmful factors
If devices are hung high in the wild with good tightness, then the device is protected from dust and rainwater, but the operation difficulty for technical personnel increases
Solution Approach 1:
The patent replaces the mechanical on-site reboot operation with an electronic remote control system. Instead of requiring technical personnel to physically access devices in difficult-to-reach locations (hung high in the wild), the system uses electronic command transmission through the command routing module to trigger power cycling remotely, eliminating the need for physical device access while maintaining protection from environmental factors.

AI summary
Disclosed are a powering off and rebooting method, apparatus and system. Wherein, the method includes: an office-end device monitoring a user-end access device; and when the office-end device monitors that the user-end access device is halted, sending a reboot command to the user-end access device; wherein the reboot command is used for indicating a power supply module in the user-end access device to perform a powering off and rebooting operation on the user-end access device. The abovementioned solution solves the problem in the related art that technical personnel have to go to the site to reboot a device if the software reset is invalid when the device is halted, so that research and development technical personnel can timely and easily power off and reboot the device without going to the site, thus treating a failure timely and reducing maintenance costs, and improving the operability and maintenance efficiency of maintenance personnel.
