Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hybrid fiber coaxial networks have inflexible and static provisioning processes for cable modem devices, limiting flexibility and requiring pre-defined associations between cable modems and access nodes, which hinders auto-detection and verification of hardware and restricts auto-installation procedures.
Innovation Solution
A method that transmits cable modem identification information and infrastructure identification information to an operations support system via a communication channel bypassing the coaxial infrastructure access point, allowing registration with an access orchestrator entity and enabling auto-installation and centralized management of cable modems, decoupling modem termination system installation from service provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cable modem devices are preconfigured with hardware addresses and statically assigned to access nodes, then network stability is maintained, but flexibility and adaptability of device assignment are reduced
Solution Approach 1:
The patent implements dynamic cable modem assignment by replacing static preconfiguration with a dynamic discovery and registration process. Cable modems can be automatically detected, verified, and assigned to access nodes through automated procedures, allowing flexible reassignment and adaptation without manual intervention, thus resolving the contradiction between adaptability and complexity
Solution Approach 2:
The patent enables cable modems to perform self-discovery and self-registration with the network. The cable modems automatically transmit their identification information to the access node and register with the operations support system, eliminating the need for manual provisioning and reducing operational complexity while maintaining flexibility
2Productivity
If cable modems are manually provisioned and registered with the network, then control and security are maintained, but installation time and operational complexity increase
Solution Approach 1:
The patent performs preliminary actions by pre-configuring access nodes with verification capabilities and pre-establishing communication channels for automatic discovery. The operations support system is pre-configured with policies and procedures that enable automated verification and assignment, allowing cable modems to be rapidly installed without manual provisioning steps
Solution Approach 2:
The patent replaces manual mechanical provisioning operations with automated electronic verification and registration processes. The manual assignment process is substituted with automatic cable modem discovery, identification information transmission, and centralized registration, significantly reducing installation time and operational complexity
3Reliability
If cable modem identification information is transmitted through the coaxial infrastructure access point, then network simplicity is maintained, but security and reliability of information transmission are reduced
Solution Approach 1:
The patent introduces an intermediary communication channel that bypasses the coaxial infrastructure access point for transmitting cable modem identification information. This intermediary path, established through alternative means (such as wireless communication or pre-configured channels), ensures reliable transmission of identification data while maintaining network simplicity by centralizing the verification process at the access node
