Solution Overview

Problem

Current wireless and wireline access networks face challenges in providing adequate Quality of Service (QoS) for emerging high-bandwidth services, as existing solutions fail to effectively manage and prioritize traffic across network boundaries, leading to degraded service experiences and increased costs for service providers.

Innovation Solution

The implementation of Device Assisted Services (DAS) that utilize centralized QoS policy coordination to establish and manage QoS channels across wireless networks, enabling differentiated service levels and traffic prioritization through device-assisted traffic control and service plan-based policies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If existing network solutions are used to provide high-bandwidth services, then network capacity increases, but service quality deteriorates and costs increase due to inability to manage traffic across network boundaries

Engineering Contradiction:
Improvenetwork capacityVSAvoidservice quality
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent introduces a boundary management system that acts as an intermediary between different network domains. This system implements QoS policies at network boundaries, coordinating traffic control between wireless and wireline networks, thereby maintaining service quality while enabling high-bandwidth services across network boundaries.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments QoS management into distinct boundary management functions that operate independently at network boundaries. This segmentation allows different network domains to maintain their own QoS policies while coordinating through standardized boundary interfaces, preventing service quality deterioration despite increased network capacity utilization.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If bandwidth is increased to meet growing digital networking demand, then user capacity increases, but service provider costs increase

Engineering Contradiction:
Improveuser capacityVSAvoidservice provider costs
Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The patent dynamically changes QoS parameters at network boundaries based on traffic conditions and service requirements. By adjusting bandwidth allocation, priority levels, and traffic routing parameters in real-time, the system optimizes network resource utilization, increasing user capacity while minimizing unnecessary bandwidth provisioning and associated costs.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If traffic is prioritized across network boundaries, then service differentiation improves, but network complexity increases

Engineering Contradiction:
Improveservice differentiationVSAvoidnetwork complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal boundary management architecture that handles multiple QoS functions through standardized interfaces and policies. This multi-functional approach enables service differentiation across various network types and traffic types without requiring separate complex management systems for each scenario, thereby reducing overall network complexity while maintaining adaptability.

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