Solution Overview

Problem

Existing wired and wireless access systems in service provider networks do not effectively exchange information, leading to negative performance impacts when one system is overloaded, affecting the other system.

Innovation Solution

Implement a resource controller to manage and optimize both wired and wireless access systems by determining congestion thresholds, identifying the breaching system, and initiating resource reductions in lower or higher priority systems as needed to alleviate congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the load on the wireless access system increases, then wireless service capacity is improved, but wired user performance deteriorates

Engineering Contradiction:

Improvewireless service capacityVSAvoidwired user performance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the wireless access system periodically reports its load status to the wired access system. The wired access system uses this feedback information to adjust its resource allocation and congestion management policies, thereby resolving the performance deterioration of wired users when wireless load increases.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary communication mechanism between the wired and wireless access systems. This intermediary allows the exchange of load status and congestion information, enabling coordinated resource management that prevents the negative impact of wireless load increases on wired user performance.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If separate management systems are used for wired and wireless access, then system complexity is reduced, but information exchange capability is lost

Engineering Contradiction:

Improvemanagement system structureVSAvoidtraffic and load information exchange

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary communication mechanism between the separate wired and wireless management systems. This intermediary enables the exchange of traffic, load, and congestion information without requiring the merging of the management systems themselves, thus resolving the information loss problem while maintaining system structure simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent maintains separate management systems for wired and wireless access while introducing segmented communication interfaces that enable selective information exchange. This segmentation approach allows information sharing for congestion management while preserving the independence and simplicity of each management system.

Inventive Principle:

Principle #1Segmentation

AI summary

Methods and systems for converged wired and wireless access optimization are described. An access system includes a wired access system, a wireless access system deployed on the wired access system, and a resource controller in communication. The resource controller determines whether traffic usage data collected from the wired access system and the wireless access system breaches one or more congestion thresholds, determines which of the wired access system and the wireless access system is a breaching access system; determines, for the breaching access system, a contributory percentage of the traffic usage data with respect to a breached congestion threshold, and initiates resource reduction at a lower priority access system when the contributory percentage of the breaching access system is same or less than a non-breaching access system, where the lower priority access system is one of the wired access system or the wireless access system.
