Innovation Solution

A method and system that utilize geospatial data and network components to detect and configure redundant physical polyline routes within a PON, ensuring the required services are delivered through multiple paths, including different OLTs, route segments, and provider facilities, thereby optimizing network connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual technician-based methods are used to connect new service locations to PON, then connection can be established, but the process is time-intensive and inconsistent

Engineering Contradiction:

Improveconnection establishment speedVSAvoidtime for technician travel and investigation

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical field investigation with an automated computational system that uses geospatial data and network topology information to automatically detect optimal splice points and route configurations, eliminating the need for technicians to physically travel to prospective service locations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service by automatically performing route detection, splice point identification, and network resource allocation without requiring manual technician intervention, allowing the network infrastructure to serve itself in identifying optimal connection paths

Inventive Principle:

Principle #25Self-service

2Ease of operation

If technicians rely on convenience or proximity in determining splice points, then connection can be established quickly, but network factors such as equipment capabilities and loading are not considered

Engineering Contradiction:

Improveease of splice point selectionVSAvoidservice provision reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary analysis of network topology, equipment capabilities, and current loading conditions before determining splice points, ensuring that all network factors are considered in advance rather than relying on post-hoc manual assessment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The automated system incorporates feedback loops that continuously evaluate network status, equipment capabilities, and service requirements to dynamically determine optimal splice points that satisfy both operational ease and service reliability constraints

Inventive Principle:

Principle #23Feedback

3Productivity

If conventional manual methods are used for connecting service locations, then connection can be established, but route redundancy is not considered

Engineering Contradiction:

Improveconnection establishment efficiencyVSAvoidroute redundancy options

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent segments the network route into multiple alternative paths by automatically detecting different physical polyline routes between service locations and network infrastructure, enabling the system to evaluate and select from multiple redundant options rather than a single manual-determined path

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The automated detection system provides multi-functionality by simultaneously identifying primary routes, alternative redundant routes, optimal splice points, and network resource requirements in a single integrated process, whereas manual methods typically address only basic connectivity

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Measurement precision

If technicians physically travel to investigate splice points, then accurate on-site assessment can be made, but the process becomes cost-intensive and time-intensive

Engineering Contradiction:

Improveon-site location assessment accuracyVSAvoidmanual field investigation complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system creates a virtual copy of the physical network infrastructure using geospatial data and topology information, allowing remote automated analysis of splice points and routes without requiring physical presence, thereby maintaining assessment accuracy while eliminating travel requirements

Inventive Principle:

Principle #26Copying

AI summary

Techniques for providing route redundancy for services at a service location of a PON include obtaining indications of a service location of the PON and a set of required services for the location; and detecting, based on geospatial locations and interconnections of optical components of the PON, that two or more physical polyline routes (each configured to support the set of required services at the service location) include different elements, e.g., different on-ramp facilities, network serving equipment, physical polyline route segments connecting to a common component of each of the two or more routes, or serving facilities of one or more providers. The detected two or more routes may be configured to be a set of redundant physical polyline routes for providing the required services to the location. One or more services may be caused to be delivered to the location via the configured set of redundant physical polyline routes.
