Terminal QoS Measurement via Packet Coloring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Internet Protocol flow performance measurement (IP FPM) methods cannot initiate quality of service measurements on a terminal side, lacking the capability to measure service quality applied to terminals.
Innovation Solution
A method and system where a terminal sends a measurement request message to a network management device, which configures and reports colored packet information, allowing the network management device to comprehensively measure the quality of service by coloring the flag FLAG field and two bits of the type of service TOS field of packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If IP FPM method is used for quality of service measurement, then measurement capability for wireless tunnel and bearer network tunnel is provided, but measurement initiation capability on terminal side is lacking
Solution Approach 1:
The patent inverts the traditional measurement initiation model by enabling the terminal (previously a passive measurement subject) to actively initiate quality of service measurements. The terminal generates measurement request messages and sends them to the network management device, reversing the conventional top-down measurement initiation approach and achieving bottom-up measurement capability.
2Measurement precision
If packet coloring is implemented by coloring flag FLAG field and two bits of type of service TOS field, then comprehensive quality of service measurement is enabled, but packet structure modification complexity increases
Solution Approach 1:
The patent changes packet parameters by modifying specific fields (FLAG field and TOS field bits) to implement packet coloring. Instead of creating entirely new packet structures, the solution leverages existing packet fields and repurposes them for measurement purposes, thereby reducing implementation complexity while achieving comprehensive measurement capability.

AI summary
Embodiments of the present invention provide a method and system for measuring quality of a service running on a terminal, and a device. The method for measuring quality of a service running on a terminal of the present invention includes: sending, by the terminal, a measurement request message to a network management device, wherein the measurement request message is used to request the network management device to measure the quality of the service; receiving, by the terminal, measurement configuration information sent by the network management device in response to the measurement request message, and coloring a packet of a service stream within a preset measurement period according to the measurement configuration information, to obtain a colored packet; sending, by the terminal, at least one of quantity information or time stamp information of the colored packet to the network management device, so that the network management device determines the quality of the service according to the at least one of the quantity information of the time stamp information of the colored packet. Quality of a service running on a terminal is comprehensively measured in the embodiments of the present invention.
