ONT Online Operation Mode Switching via OMCI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPON ONT devices are inflexible, requiring separate types for network bridge and gateway modes, making it costly for operators to adapt to market demands and incompatible with other providers' devices, limiting network compatibility.
Innovation Solution
A method for online switching of an ONT's operation mode between network bridge and gateway modes using OMCI messages, which includes testing the Ethernet UNI port's protocol management capabilities and switching modes by bringing instances into or out of the OMCI protocol management domain, enabling essential functions for each mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate GPON ONT devices are used for network bridge mode and gateway mode, then each mode can be managed independently, but device complexity increases and adaptability decreases
Solution Approach 1:
The patent implements a universal ONT device that can operate in multiple operation modes (network bridge mode and gateway mode) by dynamically switching between different management protocols (OMCI for bridge mode, TR-069 for gateway mode). This multi-functionality approach allows a single device type to replace multiple specialized devices, improving adaptability while reducing device complexity
Solution Approach 2:
The patent enables dynamic switching between operation modes during device operation. The ONT can transition between network bridge mode and gateway mode based on operational requirements, allowing flexible adaptation without requiring physical device replacement or complex initial configuration
2Adaptability or versatility
If private switching methods are used to switch between gateway mode and network bridge mode, then mode switching is possible, but compatibility with other providers' devices is lost
Solution Approach 1:
The patent implements dynamic mode switching capability that allows operators to change operation modes according to market demands. The system can switch between OMCI-managed bridge mode and TR-069-managed gateway mode, providing operational flexibility while maintaining standard protocol compatibility
Solution Approach 2:
The patent changes the management protocol parameter from OMCI to TR-069 (or vice versa) to switch between operation modes. This parameter change approach enables mode switching while maintaining compatibility with standard protocols, allowing intercommunication with devices from different providers
3Adaptability or versatility
If multiple separate device types are deployed for different operation modes, then specific mode requirements are met, but operational costs increase
Solution Approach 1:
The patent creates a universal ONT device that can fulfill multiple operation mode requirements (network bridge and gateway modes) within a single device. This eliminates the need to deploy separate device types for different modes, reducing the total quantity of devices required and lowering operational costs while maintaining adaptability to market demands

AI summary
A method for online switching of an operation mode of an ONT comprises: receiving an OMCI message in an online state by the ONT, wherein the OMCI message carries an indication message for switching the operation mode; and switching the operation mode according to the indication message by the ONT. The above-mentioned method realizes changing of an operation mode of an ONT in real-time in an online state based on the GPON standard, so that the ONT can flexibly operate in a gateway mode or a network bridge mode, and an operator management system only needs to change the operation mode of the ONT through a standard OMCI message according to a local network requirement.
