Solution Overview

Problem

Hybrid wired/wireless networks face challenges in bandwidth allocation and sharing, particularly due to mobility of access devices, interference in unlicensed frequency bands, and inefficiencies in conventional switching and signaling, which lead to reduced system throughput and performance.

Innovation Solution

A method and system for proactive bandwidth allocation and sharing in hybrid wired/wireless networks, where bandwidth is reserved and dynamically allocated based on device type and priority, using a messaging protocol for communication sessions, and incorporating bandwidth management processes to adapt to changing channel conditions and user demands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional switching and signaling is used in hybrid wired/wireless networks, then device connectivity is maintained, but system throughput is reduced due to inefficiencies

Engineering Contradiction:

Improvesystem throughputVSAvoidswitching and signaling complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by reserving bandwidth for specific access devices before actual data transmission occurs. The bandwidth reservation process happens in advance based on device type and priority, so that when data needs to be transmitted, the bandwidth is already allocated and ready, eliminating the need for complex real-time switching and signaling negotiations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a bandwidth manager as an intermediary component that handles bandwidth allocation and reservation decisions. This mediator operates between the access devices and the network infrastructure, managing the bandwidth reservation process independently and simplifying the overall switching and signaling complexity by centralizing the allocation logic.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If bandwidth is allocated dynamically in response to demand, then bandwidth utilization improves, but interference and noise increase due to reactive adjustments

Engineering Contradiction:

Improvebandwidth utilizationVSAvoidinterference and noise

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by performing bandwidth reservation before data transmission begins. The bandwidth manager reserves appropriate bandwidth slices in advance based on device type and priority, ensuring that when transmission occurs, the bandwidth is already allocated and ready. This proactive approach prevents reactive bandwidth adjustments that would cause interference and noise.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If mobility of access devices is supported, then network adaptability improves, but bandwidth allocation becomes more difficult and system performance decreases

Engineering Contradiction:

Improvedevice mobility supportVSAvoidsystem performance

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by establishing bandwidth reservations before access devices move or before data transmission begins. The bandwidth manager pre-allocates bandwidth based on device type and priority, creating a stable allocation framework that remains valid even as devices move. This eliminates the need for continuous bandwidth reallocation during mobility events, maintaining system performance while supporting device mobility.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If reserved bandwidth is allocated to high priority devices, then quality of service improves, but bandwidth sharing efficiency decreases

Engineering Contradiction:

Improvequality of serviceVSAvoidbandwidth sharing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality by assigning different bandwidth reservation characteristics to different access devices based on their type and priority. High priority devices receive reserved bandwidth with higher guarantees, while lower priority devices receive appropriate but reduced allocations. This differentiated approach ensures quality of service for critical devices while maintaining overall bandwidth sharing efficiency through proportional allocation.

Inventive Principle:

Principle #3Local quality

AI summary

Aspects of the invention provide a method and system for bandwidth allocation and sharing in a hybrid wired/wireless network. Bandwidth allocation and sharing may include reserving bandwidth for a first access device, a first access point and/or a first switch. In response to a communication session associated with one or more of the first access device, first access point and first switch, at least a portion of the reserved bandwidth may be allocated for use by the first access device, first access point and/or first switch. At least a portion of the reserved bandwidth may be utilized during the communication session. At least an unused remaining portion of the reserved bandwidth may be utilized for communication by one or more of a second access device, a second access point and a second switch.
