Home Side Device Management Table Clearing for PON Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In PON systems, the management table in home side devices cannot be easily cleared once it reaches its data limit, leading to communication issues when new devices attempt to connect, as existing technologies restrict overwriting or deleting address information, requiring manual device restarts which are time-consuming and inconvenient.
Innovation Solution
A home side device with a UNI port, access processing unit, holding unit, detecting unit, and control unit that automatically clears the management table when all communication devices go offline, allowing for automatic registration of new devices without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the management table reaches its data limit, then the device maintains data integrity by preventing overwriting, but new communication devices cannot be registered and manual restart is required
Solution Approach 1:
The home side device automatically detects link-down states of all communication devices and autonomously clears the management table without requiring manual user intervention or device restart, making the system self-maintaining while preserving data integrity through controlled clearing conditions
2Adaptability or versatility
If manual device restart is performed to clear the management table, then new devices can be registered, but communication services for other users are interrupted
Solution Approach 1:
The management table clearing operation is segmented from the overall device restart process, allowing only the management table to be cleared while keeping the access processing unit and other communication functions operational, thus enabling new device registration without interrupting services for other users
3Ease of operation
If the management table is cleared automatically, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The device pre-establishes detection mechanisms for link states of communication devices and pre-defines clearing conditions, so that when the management table needs clearing, the detection and execution can proceed automatically without complex real-time decision-making, reducing operational complexity

AI summary
A home side device according to one aspect of the present invention includes: a UNI port for a communication line used by one or a plurality of communication devices in a user's home; an access processing unit that performs upstream access control and holds a management table of address information of the communication devices; a detecting unit that detects link states of the communication devices; and a control unit that performs a process of clearing the management table when a link-down of all of the communication devices has been detected.
