Network Control Device Leave Process Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems face issues with inconsistent leave processes between control devices and communication devices, leading to unnecessary network traffic, security risks, and registration limit reductions due to incomplete deletion of information during the leave process.
Innovation Solution
A control device with a mode transition unit, initialization-reset transmitting unit, and deleting unit that facilitates a simple leave process by setting a flag and reset order for communication devices, ensuring consistent deletion of information from both the control device and communication device networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pairing process is used to allow taps to join the network, then the network can be established and communication can occur, but the leave process becomes inconsistent between control device and communication devices leading to unnecessary network traffic and security risks
Solution Approach 1:
The control device performs preliminary actions by transmitting a leave notification to the communication device before deleting its own registration information. This ensures the communication device is aware of the impending leave and can prepare accordingly, preventing inconsistent states where one device deletes information while the other retains it, thereby eliminating unnecessary traffic and security risks.
Solution Approach 2:
The system implements a feedback mechanism where the control device waits for confirmation from the communication device that it has deleted its registration information before completing the leave process. This feedback loop ensures both devices are in sync, preventing the harmful effects of inconsistent states where leftover registration information could cause unnecessary communication attempts or security vulnerabilities.
2Loss of information
If the control device stores device information about taps, then complete information management is achieved, but the registration limit is reduced when taps are not properly removed from the network
Solution Approach 1:
The invention extracts the problematic element of incomplete information deletion by implementing a structured leave process that ensures both the control device and communication devices fully remove their registration information. The control device transmits a leave notification and waits for confirmation that the communication device has deleted its information, thereby extracting the inconsistency that was causing registration slot waste.
Solution Approach 2:
The communication device performs self-service by autonomously deleting its own registration information upon receiving the leave notification from the control device. This self-service mechanism ensures that each device is responsible for its own information management, preventing the accumulation of orphaned registration entries that would reduce available slots.
3Ease of operation
If a simple pairing process is used that anyone can perform, then ease of operation is improved, but the leave process consistency between devices is not ensured
Solution Approach 1:
The control device performs a preliminary action by sending a leave notification to the communication device before deleting its own registration information. This preliminary step maintains simplicity for users while ensuring consistency behind the scenes, as the automated notification and confirmation process occurs without user intervention.
Solution Approach 2:
The leave notification message acts as an intermediary that carries the leave instruction from the control device to the communication device. This intermediary mechanism simplifies the user interface (users only need to trigger the leave process) while ensuring robust consistency through the automated message exchange and confirmation protocol.

AI summary
A control device is a control device that manages a network including a plurality of communication devices. The control device includes: a mode transition unit that makes transition to a leave mode for disconnecting a communication device from the network; an initialization-reset transmitting unit that transmits, when a notification is accepted from at least one communication device of the plurality of communication devices during the leave mode, an instruction for setting a flag and a reset order to the communication device from which the notification is accepted, the flag defining to bring the communication device back to an initial state; and a deleting unit that determines whether or not the instruction for setting the flag and the reset order are received and that deletes information about the communication device connected to the network when it is determined that the instruction for setting the flag and the reset order are received.
