Solution Overview

Problem

Existing mobile radiocommunication network infrastructures lack a transportable solution adapted for private mobile radiocommunication networks, limiting their portability and efficiency, especially for smaller networks with fewer than 1,000 subscribers.

Innovation Solution

A transportable device implementing a private mobile radiocommunication network infrastructure is developed, utilizing x86 microprocessors to create a lightweight and compact system that adheres to the LTE standard, comprising an evolved Packet Core, Home Subscriber Server, and evolved NodeB, with optional configurations for single or dual computer setups and CPRI/Ethernet network interfaces, enabling efficient operation in smaller network scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing mobile radiocommunication network infrastructures are used, then network functionality is provided, but portability and suitability for private mobile radio communication networks are insufficient

Engineering Contradiction:
ImproveportabilityVSAvoidinfrastructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the mobile radiocommunication network infrastructure into modular functional components (core network module, base station module, service module, subscriber server) that can be independently implemented on separate computing devices. This segmentation enables the infrastructure to be deployed on portable platforms while maintaining full network functionality, directly resolving the contradiction between portability and infrastructure complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements universal computing platforms (such as x86-based servers or cloud virtualization environments) that can host multiple network functions simultaneously. These universal platforms can adapt to different network scales and configurations, providing both portability and comprehensive functionality without requiring dedicated hardware for each function, thus resolving the contradiction between device complexity and adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If existing network infrastructures are deployed, then full network functionality is achieved, but efficiency for smaller networks with fewer than 1,000 subscribers is reduced

Engineering Contradiction:
Improvenetwork efficiencyVSAvoidinfrastructure scale
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic resource allocation and scalable network architecture that can adapt to varying network sizes. The modular design allows the infrastructure to dynamically adjust its capacity and configuration based on the number of subscribers and network demands, optimizing efficiency for smaller networks while maintaining the ability to scale up when needed, thus resolving the contradiction between productivity and infrastructure scale.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs parameter-based configuration and virtualization technologies that allow the network infrastructure to change its operational parameters (such as resource allocation, network topology, and service configuration) based on the specific requirements of different network sizes. This enables the same infrastructure to efficiently serve both small and large networks without requiring proportional increases in complexity, directly addressing the contradiction between productivity and infrastructure scale.

Inventive Principle:
Principle #35Parameter changes
