Solution Overview

Problem

Existing QoS measurement methods for services with multiple QoS flows result in inaccuracies due to independent measurement of each flow, leading to significant errors in the overall QoS parameter measurement results.

Innovation Solution

A network QoS measurement method that involves generating PCC rules with an association identifier for multiple data flows, allowing simultaneous or synchronized measurement of QoS parameters across these flows by PCF, SMF, and UPF, ensuring accurate and synchronized reporting of measurement results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If independent measurement of each QoS flow is performed, then measurement process simplicity is maintained, but measurement precision deteriorates due to significant errors in overall QoS parameter results

Engineering Contradiction:
ImproveQoS parameter measurement accuracyVSAvoidmeasurement process complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple independent QoS flow measurements into a unified associated measurement process. By introducing an association identifier that links multiple QoS flows, the system performs synchronized measurement across flows rather than independent measurements. This combining approach eliminates the accumulation of individual measurement errors and achieves accurate overall QoS parameter calculation while maintaining manageable process complexity through standardized association mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If associated measurement across multiple QoS flows is implemented, then QoS parameter measurement accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveoverall QoS parameter accuracyVSAvoidmeasurement system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an association identifier as an intermediary element that connects multiple QoS flows requiring associated measurement. This identifier acts as a mediator that enables the measurement system to group and synchronize measurements across different flows without requiring complex direct relationships between each flow. The intermediary simplifies the overall system architecture by providing a standardized linking mechanism that reduces measurement system complexity while achieving accurate associated measurements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If synchronized measurement is performed across n data flows, then measurement reliability is improved, but measurement time increases

Engineering Contradiction:
ImproveQoS measurement reliabilityVSAvoidmeasurement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring association identifiers in PCC rules before measurement begins. The SMF pre-establishes the relationships between multiple QoS flows through predefined association identifiers, allowing the measurement system to immediately perform synchronized measurements without requiring complex real-time relationship establishment. This preliminary configuration reduces measurement time while maintaining the reliability benefits of synchronized measurement across multiple flows.

Inventive Principle:
Principle #10Preliminary action

AI summary

Embodiments of the present disclosure provide a network quality of service (QOS) measurement method performed by multiple related computer devices acting as a policy control function (PCF), a session management function (SMF), and a user plane function (UPF) of a wireless network. The PCF generates respective policy and charging control (PCC) rules of n data flows and transmits the respective PCC rules of the n data flows to the SMF. The SMF generates respective QoS detection requests of the n data flows according to the respective PCC rules of the n data flows and transmits the respective QoS detection requests of the n data flows to the UPF, which then performs associated measurement on the QoS parameters to be measured of the n data flows accordingly.
