Solution Overview

Problem

Conventional QoS treatments in mobile networks are static and fail to adapt to dynamic changes in network usage and user requirements, leading to inefficiencies and potential failure to meet Service Level Agreements (SLAs).

Innovation Solution

A method for dynamically adjusting QoS treatments based on real-time comparison with SLAs, allowing for switching between multiple levels of QoS configurations to ensure optimal resource allocation and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If static QoS treatments are used in mobile networks, then device complexity is reduced and ease of operation is improved, but adaptability to dynamic network conditions deteriorates and SLA compliance cannot be ensured

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic QoS treatment by continuously monitoring network conditions and user equipment performance, then adjusting QoS parameters in real-time based on current network state and SLA requirements, transforming static QoS into an adaptive system

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system establishes a feedback loop where QoS performance is continuously measured against SLA targets, and adjustment decisions are made based on performance deviations, enabling closed-loop control of QoS treatments

Inventive Principle:

Principle #23Feedback
