DPOE Auto-Configuration for OLT and ONU Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing DOCSIS Provisioning Of EPON (DPOE) system requires complex and inefficient manual or command-line configurations for the optical line terminal (OLT) after optical network unit (ONU) initialization, affecting overall configuration efficiency, especially for complex service operations.
Innovation Solution
A service auto-configuration method and system that acquires a configuration file from a back-office management system containing information for both ONU and OLT, analyzes it, and configures the OLT locally while configuring the ONU via a management channel, enabling automatic setup without further OLT configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual or command-line configuration is used for OLT after ONU initialization, then configuration can be performed, but configuration efficiency is low and the process is complex
Solution Approach 1:
The patent applies preliminary action by pre-configuring OLT parameters and service information in the configuration file before ONU initialization. The OLT configuration data is prepared in advance and included in the configuration file that the ONU downloads, allowing automatic configuration without manual intervention after initialization.
Solution Approach 2:
The patent uses the configuration file as an intermediary that carries both ONU configuration information and OLT configuration information. This intermediary file enables the transfer of OLT configuration data from the network side to the ONU, eliminating the need for manual configuration and streamlining the deployment process.
2Adaptability or versatility
If individual manual configuration is performed for each service on OLT, then services can be opened, but the number of configuration steps increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-configuring all necessary OLT parameters, VLAN information, and service data in the configuration file before ONU initialization. This allows multiple services to be configured in advance rather than individually during deployment, significantly reducing configuration time while maintaining full service adaptability.
Solution Approach 2:
The patent merges ONU configuration and OLT configuration into a single configuration file. By combining both sets of configuration data and transmitting them together through the TFTP protocol, the system eliminates the need for separate manual configuration steps for each service, reducing overall configuration time while maintaining comprehensive service support.
3Reliability
If comprehensive OLT configuration is performed for complex services, then service functionality is complete, but configuration complexity and difficulty increase
Solution Approach 1:
The patent applies preliminary action by preparing complete OLT configuration data including VLAN settings, service parameters, and port configurations in advance within the configuration file. This ensures all necessary service functionality is pre-configured correctly, maintaining service reliability while eliminating the need for complex manual configuration steps during deployment.
Solution Approach 2:
The patent uses copying by transmitting the complete OLT configuration data from the network side through the configuration file to the ONU. This copying mechanism ensures that the exact configuration parameters needed for reliable service operation are automatically transferred and applied, maintaining service reliability while greatly simplifying the configuration process.

AI summary
A DPOE system and a service auto-configuration method and network based on that system are provided, wherein, the DPOE system includes an acquisition unit, an analyzing unit and a configuration unit; the service auto-configuration network includes a DPOE system, a back-office management system and an ONU; the service auto-configuration method based on that system includes: the DPOE system acquiring a configuration file from the back-office management system, wherein the configuration file includes configuration information of the ONU and configuration information of an OLT in the DPOE system; the DPOE system analyzing the configuration file and obtaining the configuration information of the ONU and the configuration information of the OLT; configuring the OLT locally and configuring the ONU via a management channel between the OLT and the ONU. Thus the service can be opened without performing further configuration to the OLT individually after the process of the ONU initialization is completed.
