Solution Overview

Problem

Current communication systems face challenges in effectively coordinating and controlling various devices due to differences in message types and proprietary communication protocols, leading to inefficient data transmission and management of remote physical layer devices.

Innovation Solution

The implementation of a Physical Layer (PHY)/Media Access Control (MAC) interface (PMI) protocol allows for remote management and control of remote PHY devices by enabling the appropriate formatting of messages between devices, facilitating the configuration of PHY operational parameters across different devices within a communication system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If devices use proprietary communication protocols and different message types, then each device can operate independently with its own protocol, but coordination and control among devices becomes difficult and inefficient

Engineering Contradiction:
Improvedevice independenceVSAvoidcoordination and control
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a standardized intermediary interface (PHY/MAC interface with PMI protocol) that mediates between devices using different proprietary protocols. This interface acts as a universal translator and coordinator, allowing devices with diverse internal protocols to interact efficiently through a common standardized interface, thus resolving the contradiction between device independence and coordination ease

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If remote PHY devices are managed without a standardized interface, then device complexity is reduced, but management and control effectiveness deteriorates

Engineering Contradiction:
Improveinterface complexityVSAvoidremote management effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent implements a universal standardized interface (PHY/MAC interface with PMI protocol) that performs multiple functions: message formatting, parameter configuration, error detection, and coordination control. This multi-functional standardized interface improves remote management effectiveness without significantly increasing device complexity, as the interface handles diverse management needs through a single unified mechanism

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If no standardized message formatting is used, then device diversity is maintained, but data transmission efficiency decreases

Engineering Contradiction:
Improvedevice diversityVSAvoiddata transmission efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the communication system into two parts: diverse proprietary protocols within individual devices and a standardized PMI interface for inter-device communication. This segmentation allows device diversity to be maintained internally while ensuring efficient standardized data transmission at the interface level, resolving the contradiction between device diversity and transmission efficiency

Inventive Principle:
Principle #1Segmentation

AI summary

A communication device is configured to support communications with other devices using a physical layer (PHY)/MAC interface (PMI) protocol. For example, a first device that includes PHY component(s) may be located remotely with respect to one or more other entities that manage and control it. In one example, a second device generates (core receives from another device) a MAC message that is based on the PMI protocol and generates a PHY message based thereon. This first device and then transmits the PHY message to the first device for use by the first device to configure PHY operational parameter(s). Generally, different messages are communicated between devices based on the PMI protocol. The first device, which may generally be referred to as a remote PHY device (RPD), can be managed and controlled by one or more other devices located separately therefrom.
