Solution Overview

Problem

Current PON detection and authentication methods are inflexible and costly due to static management of serial numbers, limiting the ability of optical line terminals (OLTs) to automatically detect and authenticate optical network units (ONUs/ONTs, which increases maintenance costs and reduces maintainability.

Innovation Solution

Implementing a logic registration code system where OLTs automatically detect and authenticate ONUs/ONTs by matching a logic registration code sent by the terminal with a pre-stored code, allowing dynamic management of terminal serial numbers and identifiers, thereby eliminating the need for static configuration and reducing maintenance costs.

Engineering Contradictions & Design Principles

1Reliability

If static management of serial numbers is used in OLT, then detection and authentication can be performed, but flexibility and maintainability are reduced

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static serial number management system into a dynamic one by introducing a logic registration code that can be automatically generated and managed by the OLT. Instead of relying on pre-configured static serial numbers, the system dynamically creates registration codes during the detection and authentication process, allowing for flexible adaptation to different terminal devices while maintaining reliable verification.

Inventive Principle:

Solution Approach 2:

The OLT performs self-service by automatically generating and managing logic registration codes without requiring manual configuration or external management system intervention. The system autonomously handles the detection, code generation, and authentication processes, eliminating the need for static pre-configuration and improving both flexibility and maintainability.

Solution Approach 1:

The OLT autonomously manages the entire authentication process by automatically generating logic registration codes and verifying terminal identities without requiring manual intervention from maintenance personnel. This self-service approach eliminates the need for complex manual configuration and reduces maintenance costs while maintaining secure authentication.

Inventive Principle:

AI summary

A method, equipment, and operation management system for detecting and authenticating a terminal in a passive optical network are provided. The method includes the following steps. The terminal has a logic registration code. A central office end receives the logic registration code sent by the terminal. The central office end judges whether the logic registration code of the terminal matches with the logic registration code stored at the central office end, and determines that the terminal is a valid terminal if the logic registration code sent by the terminal matches with the logic registration code stored at the central office end. The central office end records a terminal serial number from the valid terminal, and records a terminal identifier assigned to the valid terminal. By using the provided method, equipment, and operation management system, it is unnecessary to statically configure the terminal SN at the central office end, such that the maintenance cost of the central office end and the terminal is lowered, the flexibility of terminal detection and authentication is improved, and the maintainability of the central office end and the terminal is also enhanced.
