Relay Device for Terminal Management Without Direct Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal management systems are unable to collect information from terminal devices when they cannot communicate directly with the terminal management device, limiting their management capabilities.
Innovation Solution
A system comprising a relay device that periodically collects and transmits terminal information to a terminal management device, even without continuous instructions, and adjusts intervals based on received commands, allowing for continuous data collection and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal management device communicates directly with terminal devices via network, then information collection capability is improved, but network security and device isolation requirements are violated
Solution Approach 1:
The patent introduces a relay device as an intermediary component between the terminal management device and terminal devices. The relay device receives management instructions from the terminal management device and forwards them to terminal devices, while also collecting status information from terminal devices and relaying it back. This mediator architecture enables information collection without direct communication between management and terminal devices, resolving the contradiction between information accessibility and network isolation requirements.
2Ease of operation
If the relay device performs periodic processes only upon receiving instructions, then network control is improved, but information update timeliness deteriorates
Solution Approach 1:
The patent implements a periodic process mechanism where the relay device automatically executes information collection and forwarding operations at predetermined time intervals without requiring continuous instructions from the terminal management device. The relay device maintains a periodic process configuration that specifies collection intervals, and autonomously performs data gathering and transmission according to these intervals, thereby improving information update timeliness while maintaining operational simplicity.
3Loss of information
If the relay device repeatedly collects terminal information at short intervals, then information freshness is improved, but network load increases
Solution Approach 1:
The patent implements a dynamic interval adjustment mechanism where the relay device can modify its periodic information collection interval based on actual system conditions and received instructions. The terminal management device can send instructions to adjust the collection interval dynamically, allowing the system to optimize between information freshness and network load by extending intervals when updates are less critical and shortening them when real-time monitoring is needed.
Data Source
AI summary
A non-transitory computer-readable medium stores computer-readable program instructions executable by a processor of a relay device via which a terminal management device is communicable with a terminal device. The program instructions are configured to, when executed by the processor, cause the relay device to transmit, to the terminal management device, an inquiry for obtainment of an instruction directed to the relay device, when receiving from the terminal management device a reply including an instruction to perform a periodic process, perform the periodic process to, each time an interval elapses, repeatedly receive the terminal information from the terminal device and transmit the received terminal information to the terminal management device even without again receiving the instruction to perform the periodic process, and when receiving from the terminal management device a reply including an instruction to change the interval, change the interval.
