Service Distribution System for PON Extendibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service distribution methods in Passive Optical Networks (PON) face challenges with poor extendibility due to the complexity of extending the OMCI management entity for new services, requiring significant development workload and complicating intercommunication between OLT and ONT devices.
Innovation Solution
A method and system where the EMS generates a configuration file based on user service information, using common and personalized configuration templates, and sends it to the OLT and ONT via OMCI, allowing flexible extension and reducing coupling between devices, enabling efficient service configuration and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the OMCI management entity is extended to support new services, then service functionality is improved, but device complexity and development workload increase significantly
Solution Approach 1:
The patent segments the service distribution functionality by separating the management entity extension from the core OMCI protocol. Instead of modifying the OMCI management entity directly, the patent introduces an independent service distribution system that interfaces with existing OMCI mechanisms, thereby avoiding complexity proliferation in the management entity while still enabling new services.
Solution Approach 2:
The patent introduces an intermediary service distribution system that acts as a mediator between the OSS and the ONT. This intermediary handles service-specific configurations and translations, preventing the need to extend the core OMCI management entity for each new service, thus maintaining low device complexity while achieving high service adaptability.
2Adaptability or versatility
If the OMCI management entity is extended for new services, then service adaptability is improved, but intercommunication difficulty between OLT and ONT increases
Solution Approach 1:
The service distribution system acts as an intermediary that handles service-specific communication protocols and translations. It converts service-specific configurations into standard OMCI messages for transmission between OLT and ONT, thereby maintaining service adaptability while preventing intercommunication difficulty in the core network elements.
Solution Approach 2:
The patent creates a universal service distribution system that can handle multiple service types through a single standardized interface. This multi-functional system supports various services (VoIP, data, video, etc.) without requiring separate communication mechanisms, thus improving service adaptability while reducing intercommunication complexity.
3Adaptability or versatility
If the OMCI management entity is modified to support new services, then service extendibility is improved, but modification workload across multiple components increases
Solution Approach 1:
The patent segments the service distribution architecture into independent modules: the service distribution system, the OLT, and the ONT. This segmentation allows service extensions to be implemented solely within the service distribution system without modifying the OLT or ONT components, thereby achieving service extendibility while minimizing modification workload.
Solution Approach 2:
The patent extracts service-specific management functionality from the core OMCI management entity and places it in the independent service distribution system. This extraction allows new services to be added by configuring the service distribution system alone, without requiring modifications to numerous other components, thus reducing overall modification workload while maintaining service extendibility.

AI summary
A method of distributing service is provided, the method includes the following steps: first, the management system generates the corresponding configuration file according to the user's service information, and transmits the configuration file to the user's optical network termination (ONT) by the optical line terminal (OLT), then processes the corresponding configuration according to the configuration file. A system of distributing service and a management system as the same are provided. The solution can be used to the distributing service with the good expansibility.
