Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing OMCI protocol stack in OLT devices is complex and inflexible, limiting the deployment of virtual OMCI (vOMCI) functionality, as it requires all management entities to be implemented within the OLT device, leading to dependency on the device and reduced flexibility for service providers.

Innovation Solution

A method and system for transmitting OMCI messages where a part of the management entities associated with device information is retained in the OLT, while another part is deployed in a cloud server, reducing the dependency on the OLT device and enhancing the flexibility of the OMCI protocol stack by allowing virtual OMCI functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all management entities are deployed in the OLT device, then the OMCI protocol can be fully implemented, but the device complexity increases and flexibility decreases

Engineering Contradiction:

Improveflexibility of OMCI protocol deploymentVSAvoidcomplexity of OLT device

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the OMCI management entities into two parts: those associated with OLT device information remain in the OLT, while other management entities are deployed in the cloud server. This segmentation resolves the contradiction by distributing functionality across multiple locations, reducing OLT complexity while maintaining full OMCI capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts management entities from the OLT device and deploys them in the cloud server. This extraction reduces the complexity and resource requirements of the OLT device while preserving the complete OMCI protocol functionality through cloud-based management entities.

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If the OMCI protocol stack is deployed in the cloud server, then the flexibility and scalability improve, but the dependency on the OLT device decreases which may affect control

Engineering Contradiction:

Improveefficiency of OMCI message transmissionVSAvoidcontrol reliability of OLT device

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

By segmenting management entities between OLT and cloud server based on their association with device information, the patent ensures that critical control functions remain in the OLT while benefiting from cloud-based scalability and efficiency improvements.

Inventive Principle:

Principle #1Segmentation

AI summary

The system includes an optical line terminal, a cloud server and an optical network terminal, wherein, the optical line terminal includes a part of management entities supported by the OMCI protocol, the part of management entities is associated with device information of the optical line terminal, the cloud server supports virtual OMCI, and the cloud server includes another part of management entities supported by the OMCI protocol. According to the scheme of the disclosure, by retaining a part of MEs supported by the OMCI protocol which is associated with the device information of OLT in OLT, and deploying another part of MEs supported by the OMCI protocol in the cloud server, it can reduce or avoid the dependency of the vOMCI on the OLT device while the vOMCI is realized to reduce the complexity of the OLT device and improve the flexibility of deploying the OMCI protocol stack of different service providers.
