Solution Overview

Problem

Communication devices that support only partial frequency settings are restricted from accessing communication systems that operate with different frequency settings, limiting mobility and roaming capabilities due to strict compliance with predefined frequency requirements.

Innovation Solution

A control apparatus and method that allow communication devices with partial frequency support to enter and transmit in systems using different frequency settings by determining supported frequency bands and adjusting transmission parameters, such as channel allocation and resource management, to enable communication even with partial support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If communication devices are restricted to only access systems with fully supported frequency settings, then communication reliability is ensured, but mobility and roaming capabilities are limited

Engineering Contradiction:

Improvemobility and roaming capabilitiesVSAvoidcommunication reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the frequency band parameter from a fixed, fully-supported-only configuration to a dynamic configuration where devices can operate on partially supported bands. The network configures specific frequency bands for devices based on their capabilities, allowing devices to communicate on bands they partially support rather than requiring full support, thus improving mobility while maintaining acceptable communication reliability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies partial action by allowing communication devices to access and transmit on frequency bands they only partially support, rather than requiring complete support. The network accepts partial support scenarios and configures appropriate parameters, enabling devices to roam and access systems even with incomplete frequency band support, thereby improving adaptability without completely sacrificing reliability

Inventive Principle:

Principle #16Partial or excessive action

2Adaptability or versatility

If communication devices support all frequency bands, then global roaming capability is achieved, but device complexity increases

Engineering Contradiction:

Improveglobal roaming capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal access mechanism where the network configuration system enables devices with varying frequency band capabilities to access the same communication system. Instead of requiring each device to support all bands, the network universally configures appropriate bands for each device based on its capabilities, achieving global roaming without requiring universal device support

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces dynamic frequency band configuration where the network adjusts the set of active frequency bands based on device capabilities and network conditions. Devices can dynamically access different bands in different locations rather than requiring static full-band support, reducing device complexity while maintaining global roaming capability through adaptive network configuration

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If strict frequency band compliance is enforced, then communication protocol stability is maintained, but access flexibility for partial support devices is reduced

Engineering Contradiction:

Improvecommunication protocol stabilityVSAvoidaccess flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent segments the frequency band access into two layers: the core protocol layer remains stable and unchanged, while the frequency band configuration layer becomes flexible and adaptive. Devices can access partially supported bands through network-configured parameters without affecting the stability of the core communication protocol, thus maintaining protocol stability while improving access flexibility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The network configuration system acts as an intermediary between the stable communication protocol and the flexible frequency band requirements. It translates device partial support capabilities into protocol-compliant configurations, allowing devices with partial frequency support to access the system without compromising protocol stability, thereby enabling access flexibility while maintaining protocol integrity

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A control apparatus configured to allow a communication device supporting a first frequency setting to enter a system providing a communications facility based on a second frequency setting, wherein the first frequency setting provides only a partial support for communications in the system is disclosed. The control apparatus may be co-operative with a second control apparatus. The second control apparatus is configured to determine based on frequency setting information received from the system if it is possible to transmit to the system based on the first frequency setting supported by the communication device.
