Relay Communication Device Signal Quality Section Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal quality information notification methods fail to identify the specific section of signal quality degradation in communication paths using different communication schemes, such as Flex Ethernet and Optical Transport Network, as they do not provide a method for mapping signal quality information from Flex Ethernet sections to OTN sections.
Innovation Solution
A signal quality information notification method and relay communication device that receive relay data from one section using a first communication scheme, calculate and configure signal quality information for each physical link, and output it in a frame of a second communication scheme, specifically using the PSI field of an OPU in OTN and unused bit regions in Flex Ethernet, ensuring unique identification of degraded sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal quality information is communicated using existing methods in communication paths with multiple sections, then communication can continue with error correction, but the specific section where signal quality degradation occurred cannot be identified
Solution Approach 1:
The patent divides the communication path into multiple sections and assigns unique identification information to each section. Signal quality information is segmented and associated with specific section identifiers, allowing the receiving end to determine which section experienced degradation. This segmentation enables precise localization of problems while maintaining overall communication reliability.
Solution Approach 2:
The patent adds a new dimension to signal quality information by incorporating section identification data. Instead of merely indicating signal quality status, the information now includes spatial dimension data (which section) and quality dimension data (signal status). This multi-dimensional approach allows simultaneous transmission of both localization and quality assessment.
2Adaptability or versatility
If signal quality information is mapped between different communication schemes (Flex Ethernet to OTN), then compatibility across sections is achieved, but the complexity of mapping and coordination increases
Solution Approach 1:
The patent creates a universal signal quality information structure that can represent both Flex Ethernet and OTN section characteristics. By defining a common information format with section identification and quality status that works across different communication schemes, the system achieves multi-scheme compatibility without requiring separate processing logic for each scheme.
Solution Approach 2:
The patent introduces an intermediary information structure that bridges Flex Ethernet and OTN sections. This intermediary format acts as a common language that both communication schemes can use to exchange signal quality information, simplifying the mapping process by providing a standardized intermediate representation rather than requiring direct complex mappings between disparate schemes.

AI summary
A communication system transmits relay data through a communication path including a plurality of sections in which different communication schemes are used. A relay communication device is provided between a first section and a second section which are adjacent sections. The relay communication device includes a receiving unit receiving the relay data from the first section through a frame of a first communication scheme, and a relaying unit configuring, in a frame of a second communication scheme used to transmit the relay data to a relay destination, signal quality information representing signal quality calculated for a physical link in each of the sections through which the relay data is transmitted before arriving at the relay communication device, and outputting the frame of the second communication scheme to the second section.
