ONT Status Transmission to Service Gateway for Bandwidth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for obtaining port status and configuration control in optical access networks, particularly in the FTTH scenario, are not real-time, do not extend to service gateways, and lack operational parameter and message flow descriptions, limiting efficient bandwidth management and customer-specific configurations.
Innovation Solution
A method and device that automatically transmit ONT ID and access data from an optical termination device (ONT) to an OLT, which then forwards this information to a service gateway for real-time status updates and configuration control, using ANCP for communication and dynamically correlating port information with customer databases to manage service bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SNMP or OMCI protocols are used for status reporting, then device status can be obtained, but real-time control and configuration management extending to service gateways is not achieved
Solution Approach 1:
The patent introduces ANCP (Access Node Control Protocol) as an intermediary protocol between OLT and service gateway, enabling real-time configuration control and status monitoring to be extended beyond the traditional OLT/ONU boundary to include service gateways, thereby resolving the limitation of SNMP and OMCI protocols that are confined within OLT/ONU domains
Solution Approach 2:
The patent makes the service gateway dual-homed to both Ethernet and PON networks, enabling it to perform multiple functions including acting as an ANCP peer for control plane operations, a DHCP relay agent for IP address management, and a configuration management node, thereby achieving universal functionality that bridges traditional access network and service delivery functions
2Productivity
If ANCP protocol is used for real-time control, then configuration management is improved, but standardization currently only provides for DSL connections without FTTH design
Solution Approach 1:
The patent dynamically adapts the ANCP protocol, originally designed for DSL connections, to FTTH scenarios by making the service gateway dual-homed to both Ethernet and PON networks and enabling it to act as an ANCP peer with OLT, thereby allowing real-time configuration control and status monitoring in optical access networks without requiring a completely new protocol standard
3Adaptability or versatility
If service gateway is dual-homed to Ethernet and PON networks, then flexible service configurations are enabled, but device complexity increases
Solution Approach 1:
The patent makes the service gateway universal by enabling it to perform multiple functions simultaneously: acting as an ANCP peer for control plane operations with OLT, a DHCP relay agent for IP address management, and a configuration management node, thereby achieving flexible service configurations through a single multi-functional device rather than multiple specialized devices

AI summary
The method involves transmitting an optical network terminal identification and access data from optical network terminal (ONT) to the optical line termination (OLT) as ONT information. The ONT information is forwarded from the OLT to the ONT-service gateway so as to compare ONT information with stored information in customer database. A response is generated based on the comparison result so as to manage ONT and OLT regarding service bandwidth.
