Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multi-ring configuration in regional transmission networks increases equipment and maintenance costs due to the need for more communication paths, making it challenging to maintain high availability and reduce equipment requirements while ensuring redundancy against multiple failures.
Innovation Solution
A transmission path design apparatus and method that optimizes communication path topology by identifying and thinning out non-essential communication paths in a mesh configuration, maintaining availability against multiple failures through a model calculation unit that determines both-end path values and generates output data for reduced equipment needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh configuration is adopted to increase availability against multiple failures, then reliability is improved, but the quantity of equipment increases
Solution Approach 1:
The patent extracts and removes non-essential communication paths from the mesh configuration through the thinning-out process. The model calculation unit identifies and eliminates redundant paths that do not contribute to multiple failure resilience, thereby reducing equipment quantity while preserving the core reliability function.
Solution Approach 2:
The patent applies partial action by implementing thinning-out only for communication paths that connect base stations with already-sufficient connectivity. Not all paths are removed uniformly - only those where removal does not compromise the multiple failure availability requirement, thus optimizing the balance between equipment reduction and reliability maintenance.
2Quantity of substance
If the number of communication paths is reduced to decrease equipment quantity, then the quantity of substance is improved, but reliability deteriorates
Solution Approach 1:
The patent employs feedback through the model calculation unit that continuously evaluates the impact of thinning-out operations on network reliability. The system calculates both-end path values and determines whether removing a communication path would compromise multiple failure availability, providing feedback control to prevent excessive thinning that would degrade reliability.
Solution Approach 2:
The patent performs preliminary analysis by calculating both-end path values and identifying thinning-out target communication paths before actual removal. This preliminary action ensures that only paths whose removal will not affect multiple failure availability are selected for thinning, thereby preventing reliability deterioration.
3Reliability
If a multi-ring configuration is used to ensure path redundancy, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the network into base stations with different connectivity characteristics, identifying a first group of base stations with high connectivity (more than a specified number of communication-path routes) and a second group with lower connectivity. This segmentation allows differential thinning-out strategies, simplifying the overall configuration while maintaining redundancy where critical.
Solution Approach 2:
The patent applies local quality by implementing thinning-out selectively based on local network conditions at each base station. The model calculation unit evaluates the specific connectivity context of each base station and determines appropriate thinning-out targets locally, rather than applying a uniform reduction strategy, thereby maintaining path redundancy in critical areas while reducing complexity elsewhere.

AI summary
To easily design a communication path topology optimized in view of reducing the amount of equipment needed under the condition that availability against multiple failures in a network is maintained. A transmission path design apparatus (100) performs: a step (S14) of extracting, from the multiple base stations, a first group of base stations whose number of communication-path routes connected is large, based on transmission network model initial data (D0); a step (S16) of extracting a first group of communication paths connecting the base stations in the first group; a step (S16) of calculating a both-end path value (d_i,j) for each communication path in the first group; and steps (S18 to S24) of determining the communication path whose both-end path value satisfies a predetermined condition as a thinning-out target communication path, and generating output data Dy in which the thinning-out target communication path is reflected on the transmission network model initial data. The optimized output data (Dy) can be generated by extracting a deletable communication path in order from the model of the initial data (D0).
