Solution Overview

Problem

Current telecommunications systems face challenges in efficiently managing radio frequency spectrum allocation, leading to issues like dropped calls and slow internet access during emergencies due to overtaxed networks, while underutilized emergency service spectrum remains unused.

Innovation Solution

A dynamic spectrum arbitrage system that includes a Home Subscriber Server (HSS), Mobility Management Entity (MME), dynamic spectrum controller (DSC), and dynamic spectrum policy controller (DPC) to dynamically allocate and manage RF spectrum, synchronizing user profile information and modifying quality of service profiles to prioritize emergency communications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If RF spectrum is allocated to commercial wireless services, then network capacity for consumers is improved, but emergency service communication reliability deteriorates due to spectrum congestion

Engineering Contradiction:

Improvenetwork capacity for consumersVSAvoidemergency service communication reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts spectrum allocation between commercial and emergency services based on real-time conditions. The spectrum allocation mechanism transitions from static to dynamic, allowing the network to adapt spectrum resources to changing demands and ensure emergency services can access required bandwidth during critical situations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the allocation parameter of RF spectrum dynamically. By adjusting spectrum allocation parameters in response to detected emergency conditions, the system ensures that emergency services receive adequate spectral resources while commercial services operate efficiently during normal conditions.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If RF spectrum is dedicated to emergency services, then emergency communication reliability is improved, but commercial network capacity deteriorates due to underutilization

Engineering Contradiction:

Improveemergency service communication reliabilityVSAvoidcommercial network capacity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The RF spectrum is designed to serve multiple functions - both commercial wireless services and emergency services - rather than being dedicated exclusively to one purpose. This multi-functional allocation allows the same spectral resources to benefit both commercial productivity and emergency reliability through dynamic sharing mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The spectrum allocation system automatically detects emergency conditions and reallocates resources without requiring manual intervention. The network self-adjusts to prioritize emergency services when needed while maintaining commercial service efficiency during normal operations, eliminating the need for permanent dedicated emergency spectrum.

Inventive Principle:

Principle #25Self-service

3Device complexity

If spectrum allocation is static, then network management simplicity is maintained, but adaptability to changing traffic demands deteriorates

Engineering Contradiction:

Improvespectrum management complexityVSAvoidspectrum allocation adaptability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The system incorporates feedback mechanisms that continuously monitor network conditions, traffic demands, and emergency states. This feedback drives automatic spectrum reallocation decisions, enabling the network to adapt dynamically to changing conditions while maintaining manageable complexity through automated control loops.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system pre-configures spectrum allocation policies and decision-making frameworks that enable rapid adaptation when emergencies occur. By establishing predetermined allocation rules and automated response mechanisms in advance, the system can quickly adjust spectrum resources without complex real-time calculations during critical situations.

Inventive Principle:

AI summary

A dynamic spectrum arbitrage (DSA) system includes a home subscriber server (HSS), a mobility management entity (MME), an eNodeB, a dynamic spectrum controller (DSC), and a dynamic spectrum policy controller (DPC). The DSC may receive resource allocation information from the DPC, and send updated information and instructions to the HSS. The HSS may be configured to receive information from the DSC, detect changes to HSS subscription information (e.g., user profile information), determine whether the changes affect the information managed/stored by an MME component, and send the detected changes to the MME component when the HSS determines that the changes affect the information managed/stored by the MME. The MME component may use the information included in the received messages to add, remove, or modify the MME's stored subscription information or user profile information. The MME component may then communicate these updates, additions, or changes to the HSS component.
