Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for quality of experience (QoE) measurement in terminals are inefficient and can lead to overload, affecting normal terminal operation, particularly when terminals are in an overloaded state.

Innovation Solution

A method for determining the load state of a terminal using terminal running indicators, such as resource usage, CPU power, or wireless load, to decide whether to perform QoE measurement, and a method to divide QoE measurement reports into sub-reports for efficient transmission and caching of QoE measurement reports in access stratum cache regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If QoE measurement is performed continuously to understand user experience, then measurement completeness is improved, but terminal overload increases

Engineering Contradiction:

Improvemeasurement completenessVSAvoidterminal overload

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by making the QoE measurement configuration adjustable based on terminal load state. The network can dynamically modify measurement parameters, thresholds, and reporting frequencies according to real-time terminal conditions, transitioning between high-monitoring modes (when load is low) and reduced-monitoring modes (when load is high), thus resolving the contradiction between measurement completeness and terminal overload

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes key parameters such as measurement thresholds, reporting intervals, and configuration frequencies based on terminal load state. By adjusting these parameters dynamically, the system can maintain measurement effectiveness during normal operation while reducing measurement intensity when terminal overload is detected, balancing measurement completeness with terminal resource consumption

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If QoE measurement parameters are configured frequently to adapt to changing conditions, then adaptability is improved, but terminal processing load increases

Engineering Contradiction:

Improveparameter adaptabilityVSAvoidterminal processing efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements periodic action by configuring QoE measurement parameters at specific intervals rather than continuously. The network can set configuration periods based on terminal characteristics and network conditions, performing parameter updates only when necessary (e.g., during handover, when load thresholds are crossed, or at scheduled intervals), thereby maintaining adaptability while reducing unnecessary processing load

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies self-service by enabling terminals to autonomously monitor their own load states and trigger appropriate responses without constant network intervention. Terminals can self-assess their processing capacity and proactively adjust measurement reporting behaviors or request parameter modifications, reducing the frequency of network-initiated configuration changes and associated processing overhead

Inventive Principle:

Principle #25Self-service

3Speed

If QoE measurement reports are transmitted immediately to ensure timely feedback, then response speed is improved, but network bandwidth consumption increases

Engineering Contradiction:

Improvefeedback response speedVSAvoidnetwork bandwidth usage

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

The patent applies segmentation by dividing QoE measurement reports into multiple segments that can be transmitted separately. Instead of sending complete report packages immediately, the system can transmit only critical segment information (such as threshold violations or significant changes) while deferring less critical data transmission, thereby maintaining timely feedback for important decisions while reducing overall bandwidth consumption

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by pre-configuring measurement thresholds, reporting triggers, and data filtering criteria before actual measurement occurs. This allows the terminal and network to agree in advance on what constitutes actionable information, enabling selective transmission of only pre-identified important data rather than transmitting all raw measurement data immediately, thus reducing bandwidth usage while maintaining timely feedback for critical decisions

Inventive Principle:

Principle #10Preliminary action
