Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Observability within public cloud-based telecommunications systems is complicated and costly, making it difficult to efficiently monitor and resolve issues in telecommunications networks.
Innovation Solution
A framework utilizing hardware and software within privately owned components, employing split-light signal monitoring to enhance observability by directing optical signals to both primary network functions and observability modules for improved information gathering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If public cloud-based observability systems are used, then monitoring coverage is improved, but cost and system complexity increase
Solution Approach 1:
The patent extracts the observability function from the public cloud environment and implements it locally at the cell site using private hardware components. The optical signal tapping mechanism is deployed at the network edge, allowing monitoring data to be collected and processed on-premises rather than relying on external cloud infrastructure, thereby reducing both cost and complexity while maintaining monitoring coverage.
2Loss of information
If public cloud-based observability systems are used, then monitoring coverage is improved, but cost increases
Solution Approach 1:
The system enables self-service monitoring by implementing local observability capabilities at the cell site. The private hardware components and optical signal tapping mechanisms are deployed and operated autonomously within the private network infrastructure, eliminating the need to pay for external cloud-based monitoring services while maintaining comprehensive monitoring coverage.
3Loss of information
If optical signals are split to multiple destinations, then observability information gathering is improved, but signal loss increases
Solution Approach 1:
The patent uses optical signal copying through splitting, where the original optical signal is replicated into multiple copies that are directed to different destinations including the central unit and observability modules. This copying approach allows the same signal to be monitored at multiple points simultaneously without degrading the primary signal transmission, as each copy carries the same information independently.

Implementation Method 1
an optical splitter. The optical splitter is configured to split the optical signal into a first part and one or more second parts
Data Source
AI summary
A virtual cell site router, including a first module configured to receive an optical signal from a distributed unit and an optical splitter. The optical splitter can split the optical signal into a first part and one or more second parts. The first part of the signal is directed towards a unit, and the one or more second parts of the signal is directed toward one or more modules configured to monitor an aspect of the network.
