Solution Overview

Problem

Wireless communication devices face additional usage charges and penalties when accessing communication services through roaming wireless access systems, as they typically adhere to the data rates set by the visited network operators without the ability to selectively manage data rates based on the service operator.

Innovation Solution

A method and device that determine the service operator of a wireless access system and selectively choose a data rate, allowing the device to request and receive communication services at a preferred data rate, thereby managing data rates based on the service operator to optimize usage and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication devices access communication services through roaming wireless access systems, then communication service availability is improved, but additional usage charges and penalties increase

Engineering Contradiction:

Improvecommunication service availabilityVSAvoidroaming charges

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent changes the data rate parameter based on the service operator being accessed. When roaming, the device selects lower data rates that incur fewer charges, while when accessing the home network, it can utilize higher data rates without additional penalties. This dynamic parameter adjustment resolves the contradiction by adapting the data rate to the operational context.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If wireless communication devices adhere to data rates set by visited network operators during roaming, then network compatibility is improved, but cost control deteriorates

Engineering Contradiction:

Improvenetwork compatibilityVSAvoidcost control

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent implements dynamic data rate selection where the device can adjust its data rate based on whether it is roaming or accessing its home network. The device determines the service operator and dynamically selects appropriate data rates from available options, rather than statically adhering to operator-set rates. This dynamic approach maintains compatibility while enabling cost control.

Inventive Principle:

Principle #15Dynamics

3Loss of energy

If wireless communication devices select lower data rates during roaming, then roaming charges are reduced, but communication service quality deteriorates

Engineering Contradiction:

Improveroaming chargesVSAvoidcommunication service quality

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent applies different data rate quality levels based on the local operational context. When roaming, lower data rates are selected to reduce charges, while when accessing the home network, higher quality data rates are utilized. This local quality adjustment resolves the contradiction by optimizing for cost during roaming while preserving service quality when financially permissible.

Inventive Principle:

Principle #3Local quality
