Solution Overview

Problem

Implementing multiple independent services on a customer's premises requires multiple access devices, leading to decreased performance and increased hardware costs due to the use of splitters and coaxial data lines.

Innovation Solution

A single access device with multiple modem software stacks (MSS) using separate system-on-chips (SoCs) to communicate with registration servers and local area networks, each with unique MAC addresses, eliminating the need for splitters and enhancing communication speeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple access devices are used to implement multiple independent services, then service independence is improved, but hardware costs and device complexity increase

Engineering Contradiction:

Improveservice independenceVSAvoidhardware costs

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple modem software stacks (first MSS and second MSS) into a single access device, allowing multiple independent services to be implemented within one device rather than requiring separate physical access devices for each service

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The access device is designed with multi-functionality to support multiple independent services through separate modem software stacks, each capable of independent operation and service provision within the same hardware platform

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If splitters and coaxial data lines are used to connect multiple access devices, then service coverage is improved, but communication speed decreases

Engineering Contradiction:

Improveservice coverageVSAvoidcommunication speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent extracts and eliminates the need for splitters and coaxial data lines from the system architecture by implementing multiple modems within a single access device, removing the performance-decreasing components while maintaining service coverage capability

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A method includes initiating, by a first system-on-chip (SoC) of an access device, a first modem software stack (MSS) operable to communicate with a registration server and operable to communicate with a first local area network (LAN) port of the access device. The method includes initiating, by a second SoC of the access device, a second MSS operable to communicate with the registration server and operable to communicate with a second LAN port of the access device. The method includes registering and provisioning the first MSS as a first modem with the registration server using a first media access control (MAC) address. The method includes registering and provisioning the second MSS as a second modem with the registration server using a second MAC address.
