Solution Overview

Problem

The existing virtual OMCI (vOMCI) function in GPON networks fails to consider device-dependent and time-sensitive management entities like OLT-G ME, which requires timely device information such as superframe and time of day data, leading to potential message timeouts.

Innovation Solution

A method and apparatus for transmitting OMCI messages that involve a cloud server generating messages without valid device association information and an optical line terminal filling in the necessary device-specific data, ensuring timely delivery of these messages to the optical network terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the OMCI protocol stack is moved to the cloud for vOMCI, then the flexibility and reduced complexity of OLT device are improved, but the ability to handle device-dependent and time-sensitive MEs deteriorates

Engineering Contradiction:
Improveflexibility of deploying OMCI protocol stackVSAvoidhandling of device-dependent and time-sensitive MEs
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the OMCI message processing into two types: generic OMCI messages handled by the cloud-based vOMCI function, and device-dependent OMCI messages requiring OLT assistance. This segmentation allows the system to maintain flexibility for general configurations while ensuring reliability for time-sensitive, device-specific management entities through selective local processing at the OLT.

Inventive Principle:
Principle #1Segmentation

2Productivity

If cloud server generates OMCI messages without device association information, then the productivity and automation of vOMCI are improved, but the completeness and usability of OMCI messages deteriorates

Engineering Contradiction:
Improveautomation of OMCI message generationVSAvoiddevice association information in OMCI messages
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The cloud-based vOMCI function performs preliminary generation of OMCI messages with generic configuration data before transmission to the OLT. The OLT then completes the message by adding device-specific association information in a subsequent step. This preliminary action enables automated mass configuration while preserving the ability to customize messages for specific devices.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The OLT acts as an intermediary between the cloud-based vOMCI function and the ONT. It receives incomplete OMCI messages from the cloud, supplements them with necessary device association information, and forwards the complete messages to the ONT. This intermediary role bridges the gap between automated cloud processing and device-specific requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If OMCI messages are transmitted without timely device information, then the simplicity of vOMCI implementation is improved, but the timing compliance and reliability of message delivery deteriorates

Engineering Contradiction:
Improvesimplicity of vOMCI implementationVSAvoidtiming compliance for superframe delivery
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent segments OMCI message processing into cloud-based generic message generation and OLT-based device-specific message completion. This segmentation allows most messages to follow a simple automated path while time-sensitive messages receive expedited local processing, ensuring timing compliance without significantly increasing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies different processing qualities to different message types: generic OMCI messages receive standard cloud-based processing, while device-dependent messages requiring timing compliance receive priority local processing at the OLT. This local quality differentiation ensures timing requirements are met for critical messages while maintaining simplicity for routine operations.

Inventive Principle:
Principle #3Local quality

AI summary

The present disclosure provides a method, apparatus and system for transmitting OMCI messages. The method comprises: receiving an OMCI message from a cloud server, wherein the cloud server supports vOMCI; judging whether the received OMCI message is associated with device information of the optical line terminal, if so, obtaining device association information corresponding to the received OMCI message, filling the device association information into the received OMCI message, and sending the filled OMCI message to the optical network terminal, otherwise, sending the received OMCI message directly to the optical network terminal. This disclosure, for OMCI messages requiring OLT assistance, by generating OMCI messages that do not carry valid device association information in the cloud server and fills them in the OLT, the integrity of the vOMCI can be maintained and it is ensured that all OMCI messages can reach the ONT before a specific superframe reaches the ONT, thereby meeting the timing requirements.
