Solution Overview
Problem
Existing solutions lack a unified configuration management method for home gateway access devices in PON networks, leading to high maintenance costs and complexity.
Innovation Solution
A configuration data distribution method that encapsulates data according to preset identifiers and distributes it to corresponding gateways, allowing for unified management of terminals using different gateways by determining the encapsulation manner based on ONU identifiers and using user data configuration templates to differentiate between entity home gateways and virtual remote gateways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If home gateway functions are remotely deployed and core functions are realized on xPON OLT device, then maintenance cost is reduced and technical complexity of user-side device is reduced, but unified configuration management solution for different gateway access devices is lacking
Solution Approach 1:
The patent segments configuration data into different types (service configuration data, line configuration data, etc.) and applies different distribution strategies for each type. This segmentation allows the system to manage complex configurations of different gateways (entity home gateway and virtual remote gateway) in an organized manner, resolving the contradiction between reduced maintenance cost and increased configuration management complexity.
Solution Approach 2:
The patent introduces an intermediary mechanism (configuration data distribution method involving OLT, ONU, and gateway devices) that mediates between the core network and user-side devices. This intermediary approach enables unified configuration management across different gateway types while maintaining the benefits of remote deployment and reduced maintenance costs.
2Adaptability or versatility
If configuration data is distributed to ONUs for local effectiveness to guarantee service forwarding, then service transformation functions are realized, but operational complexity and maintenance workload increase
Solution Approach 1:
The patent implements dynamic configuration data distribution where the OLT determines whether to distribute service configuration data or line configuration data based on the ONU type and gateway status. This dynamic approach enables flexible service transformation capabilities while simplifying operation through automated, context-aware configuration management rather than static manual configuration.
Solution Approach 2:
The patent enables self-service configuration distribution where the OLT automatically determines and distributes appropriate configuration data to ONUs based on their registered gateway type. The system performs self-configuration without requiring manual intervention, thereby achieving service transformation capabilities while reducing operational complexity and maintenance workload.

AI summary
The present invention provides a configuration data distribution method, used for solving a problem in the existing art that a unified configuration and management solution of two home gateway access devices does not exist. The configuration data distribution method includes: determining an encapsulation manner of configuration data according to identifiers of Optical Network Units (ONUs) and a preset corresponding relationship between the identifiers of the ONUs and the encapsulation manner of the configuration data of the ONUs; and encapsulating the configuration data according to the determined encapsulation manner, and distributing the encapsulated configuration data to corresponding gateways according to the encapsulation manner of the ONUs or the identifiers of the ONUs. According to the solution, terminals using different gateways are managed and configured in a unified manner.
