Solution Overview

Problem

In current Passive Optical Networks (PON), user authentication is based on hardware equipment identity, leading to a coupling between the equipment and the end-user, making it difficult for users to move services to new locations without re-provisioning or re-installing equipment.

Innovation Solution

The method involves an Optical Line Terminal (OLT) discovering client devices, receiving SIM-authentication information, and forwarding it to an Authentication Server to authenticate end-users, creating a relationship between the device and user, allowing service activation based on user subscriptions and hardware-dependent definitions, decoupling the user from the hardware.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user authentication is based on hardware equipment identity, then equipment security and control are improved, but service mobility and user flexibility deteriorate

Engineering Contradiction:
Improveequipment securityVSAvoidservice mobility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The authentication system is segmented into two independent components: hardware authentication (for equipment security) and SIM-based user authentication (for service mobility). The OLT first authenticates the ONU/ONT hardware identity, then separately authenticates the user's SIM card information. This segmentation allows each component to fulfill its specific function without compromising the other, resolving the contradiction between equipment security and service mobility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The SIM card information acts as an intermediary between the user and the network services. Instead of directly binding services to hardware identity, the system uses SIM authentication as a mediator that links the user to the services. This intermediary layer enables service transfer between different locations and devices while maintaining security, as the SIM card portably carries user identification and subscription information.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If service activation is coupled with equipment installation, then hardware control and provisioning simplicity are improved, but user flexibility and service transfer capability deteriorate

Engineering Contradiction:
Improveprovisioning simplicityVSAvoidservice transfer capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The service activation process is segmented into two independent phases: equipment installation (hardware provisioning) and user service activation (SIM-based provisioning). The OLT can complete hardware provisioning when the ONU/ONT is installed, but service activation is deferred until SIM authentication is performed. This segmentation allows equipment to be installed and prepared in advance, while service activation can occur at any location where the user has service subscription, enabling service transfer without re-provisioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary hardware provisioning and equipment setup during installation, but delays actual service activation until SIM authentication is completed. This preliminary action allows the network to prepare the equipment in advance, while the actual service activation can be performed remotely and transferred between locations. The OLT stores the user's service subscription information and can activate services at any authorized location without requiring physical re-provisioning of the equipment.

Inventive Principle:
Principle #10Preliminary action

AI summary

An Optical Line Terminal (2) connected to a Passive Optical Network provides a service to a Client device (1, 8) by receiving its hardware identity, as well as SIM-authentication information, from the Client device, and forwarding to the Authentication Server (3). After authentication of an end-user, a relationship is created between the Client device and the end- user. The OLT activates a service, based on service subscriptions associated with the end-user and on hardware - dependent service definitions associated with the Client device.
