Communication Device Management via Automatic Function Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication device management systems face challenges in reducing unauthorized use while being cumbersome for managers and requiring complex function implementation across multiple device types, as they need to manually cancel function restrictions and notify servers of device startups.
Innovation Solution
A communication device management device that detects changes in communication possibility through responses to confirmation signals, automatically imposing or canceling function restrictions based on these signals, thereby reducing the need for manual intervention and simplifying the implementation of starting notifications across diverse device types.

Engineering Contradiction Analysis
1Reliability
If manual operation is required to cancel function restriction of communication devices, then security control can be implemented, but manager's workload increases
Solution Approach 1:
The communication device automatically performs function restriction and cancellation operations itself based on startup detection, eliminating the need for manual manager intervention. The device self-manages its security state by detecting startup conditions and automatically applying or removing function restrictions without requiring manager operation.
Solution Approach 2:
The system implements automatic detection of communication device startup through server communication, creating a feedback loop that triggers automated function restriction management. When the server detects device startup through communication attempts, it automatically initiates the appropriate security measures without requiring manual input from the manager.
2Reliability
If communication device notifies server of startup, then server can detect startup and implement security measures, but device complexity increases due to notification function implementation
Solution Approach 1:
The server acts as an intermediary that performs the complex startup detection and security management functions. Instead of implementing complex notification functionality in each communication device, the server receives standard communication attempts and uses these as indicators of startup, thereby centralizing the complexity in the server rather than in the devices.
Solution Approach 2:
The server implements a universal startup detection mechanism that works across multiple types of communication devices without requiring device-specific modifications. The same server-side logic handles startup detection for all devices, making the solution universally applicable and reducing individual device complexity.

AI summary
A communication device management device includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: detect a change in possibility/impossibility of communication with a communication device, based on a response from the communication device to a confirmation signal to be transmitted at every predetermined time; and perform, when a restriction is imposed on a predetermined function of the communication device in which the communication possibility/impossibility is changed from impossible to possible, the restriction after canceling the restriction of the communication device, and perform, when the restriction of the communication device is not imposed, the restriction of the communication device.
