Solution Overview

Problem

Mobile telecommunications networks face challenges in managing increasing data traffic volumes, leading to service degradation and high operational costs due to hierarchical and expensive architectures, proprietary platforms, and inefficient use of capacity, with current solutions failing to effectively address network capacity and revenue imbalances.

Innovation Solution

The introduction of a control means that can intelligently select and allocate functions, applications, and bandwidth across access nodes and gateway sites, allowing for intelligent offloading of data traffic directly to the internet, caching, and optimizing content delivery, thereby reducing the burden on the core network and enhancing resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a hierarchical network architecture with proprietary platforms is used, then network control and management are simplified, but device complexity and cost increase, and adaptability decreases

Engineering Contradiction:
Improvenetwork controlVSAvoidarchitecture complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the network architecture into distributed access nodes with embedded control functions rather than a centralized hierarchical structure. Each access node operates semi-autonomously, making local routing and resource allocation decisions, which reduces overall system complexity while maintaining operational control through standardized interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements universal standardized interfaces and protocols that enable different manufacturers' devices to interoperate seamlessly. The access nodes are designed with multi-functional capabilities to handle various traffic types and services through common architecture, reducing the need for proprietary specialized equipment.

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

2Reliability

If centralized core network routing is used, then network security and control are improved, but data traffic efficiency decreases and backhaul costs increase

Engineering Contradiction:
Improvenetwork securityVSAvoiddata traffic efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent enables access nodes to perform intelligent local routing decisions based on real-time network conditions, traffic patterns, and service requirements. This distributed intelligence allows traffic to be routed optimally at the network edge without constantly traversing the core network, improving efficiency while maintaining security through standardized control planes.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces standardized interface protocols and control mechanisms that act as intermediaries between distributed access nodes and the core network. These intermediaries enable autonomous local decision-making while maintaining centralized security policies and coordination, resolving the conflict between distributed efficiency and centralized control.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If flat-rate unlimited data pricing is used, then customer satisfaction and data usage increase, but network capacity is overwhelmed and revenue cannot cover costs

Engineering Contradiction:
Improveservice flexibilityVSAvoiddata traffic volume
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent implements dynamic resource allocation and bandwidth management at access nodes that can adapt to varying traffic demands in real-time. The system dynamically adjusts quality of service parameters, prioritizes critical traffic, and manages capacity allocation based on current network conditions, enabling sustainable high-volume data transmission without overwhelming the network.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where access nodes continuously monitor network utilization, traffic patterns, and resource consumption. This feedback enables real-time adjustment of pricing models, capacity allocation, and traffic management policies to balance customer demand with network sustainability and revenue requirements.

Inventive Principle:
Principle #23Feedback

4Ease of manufacture

If conventional base stations without intelligent processing are used, then device cost is reduced, but network intelligence and local routing capability decrease

Engineering Contradiction:
Improvebase station costVSAvoidlocal routing capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent enables base stations to perform intelligent local routing, caching, and traffic management functions autonomously without requiring complex centralized control for every decision. The access nodes self-manage local traffic optimization, content caching, and resource allocation, reducing the intelligence burden on the core network while maintaining advanced capabilities at lower cost.

Inventive Principle:
Principle #25Self-service
