Solution Overview

Problem

Current network connection methods, such as MobileIP, often result in performance degradation and lost connections due to exceeding bandwidth limits in wireless networks, as they do not effectively assess available bandwidth before establishing connections.

Innovation Solution

A method and system that determine the required bandwidth for network connections and assess availability before creating them, allowing for controlled hand-over of connections between networks, including different protocols, to prevent performance drops and lost connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If network connections are created without assessing available bandwidth first, then connection speed is improved, but network performance deteriorates and connections are lost

Engineering Contradiction:

Improveconnection speedVSAvoidnetwork performance

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent applies preliminary action by assessing available bandwidth before creating network connections. The system checks whether sufficient bandwidth is available on the target network before initiating connection establishment, preventing connection failures and performance degradation that occur when connections are created without prior bandwidth assessment.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple network connections are made simultaneously, then connectivity options are improved, but bandwidth exhaustion occurs and performance drops

Engineering Contradiction:

Improveconnectivity optionsVSAvoidnetwork performance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary bandwidth assessment before establishing each network connection. This ensures that sufficient bandwidth is available before connections are created, preventing bandwidth exhaustion and maintaining network performance even when multiple connections are attempted simultaneously.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the system continuously monitors available bandwidth and uses this information to make informed decisions about connection establishment. The feedback loop ensures that connections are only created when bandwidth requirements can be met, maintaining optimal network performance.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If network hand-over is attempted without bandwidth assessment, then mobility is improved, but connection loss increases

Engineering Contradiction:

ImprovemobilityVSAvoidconnection stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action during network hand-over by assessing available bandwidth on the target network before completing the hand-over process. This ensures that the migrating connection is successfully transferred to a network that can accommodate it, preventing connection loss and maintaining mobility.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method of at least partially creating a network connection from a computing device to a network wherein the method comprises determining the bandwidth associated with the network connection that it is desired to make to the computing device from the network and assessing whether this bandwidth is available from the network before commencing creating the connection. Generally, this method will be used during a hand-over process from an existing network to the network.
