Master Unit Selection Logic for Independent Network Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale networks composed of multiple communication terminal devices, unintended integration of independent networks occurs due to the unintentional detection of multiple master units, leading to misidentification and improper network grouping.
Innovation Solution
Communication terminal devices employ a storage system to store judging criteria and group identification information, allowing them to monitor and switch operation modes based on priority and group affiliation, preventing the selection of unsuitable master units by using blacklist information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices monitor and detect master units in large-scale networks, then network integration capability is improved, but unintended detection of foreign network master units occurs causing false integration
Solution Approach 1:
The patent introduces group identification information as an intermediary layer between device detection and network integration decisions. This mediator allows devices to detect master units across networks while using group IDs to filter and distinguish between friendly and foreign networks, preventing false integration of unrelated networks
Solution Approach 2:
The patent segments the network space by introducing group identification information that divides the network into distinct groups. This segmentation allows master units to be detected across different networks while preventing unintended integration by checking whether detected master units belong to the same group, thus maintaining network boundaries
2Productivity
If devices use master preference criteria to select master units, then master unit selection efficiency is improved, but unintended selection of inappropriate master units occurs
Solution Approach 1:
The patent applies preliminary action by pre-configuring group identification information and master preference criteria in devices before network operation. This allows devices to quickly evaluate detected master units against pre-set criteria, maintaining high selection efficiency while ensuring appropriate master units are chosen through pre-established selection rules
Solution Approach 2:
The patent changes the selection parameters by introducing group identification as an additional criterion alongside master preference. This parameter change allows devices to maintain efficient selection through clear criteria while improving accuracy by filtering candidates based on group membership, ensuring only appropriate master units within the same network are selected

AI summary
A communication terminal device has circuitry configured to: judge, based on received information, whether or not source of the received information is intra-group communication destination; monitor whether or not the intra-group communication destination is the master unit based on the judgement; acquire the judging criterion information of the intra-group communication destination detected as the master unit; and switch, while the self device is operating by a master unit operation mode and when the other master unit is detected by monitoring, a master unit operation mode of the self device to a slave unit operation mode based on the judging criterion information of the self device and the judging criterion information of the other master unit.
