QoS Detection Packets for 5G URLLC Service Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G network technologies lack an effective solution for real-time quality of service (QoS) detection across different QoS flows, which is critical for ensuring reliable and low-latency communications in ultra-reliable low-latency communications (URLLC) scenarios, particularly for life-safety and production-safety services.
Innovation Solution
A method and system for detecting QoS by using detection packets with a 3GPP network protocol header, allowing for link connectivity, service transmission performance, and loopback detection types, enabling the identification of faults and performance issues in QoS flows through periodic packet transmission and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If BFD mechanism is used for connectivity monitoring, then link connectivity can be detected, but QoS detection for different service flows cannot be performed
Solution Approach 1:
The patent segments the detection function by creating different detection packet types (connectivity detection packets, transmission performance detection packets, loopback detection packets) that can be independently selected and configured for different QoS flows, allowing specialized detection for each flow's specific requirements
Solution Approach 2:
The patent creates a universal detection packet framework that can perform multiple detection functions (connectivity, transmission performance, loopback) through a single standardized packet structure, enabling one system to serve multiple QoS detection needs across different service flows
2Reliability
If real-time QoS detection is implemented for URLLC services, then service reliability can be ensured, but detection complexity and resource consumption increase
Solution Approach 1:
The patent implements periodic detection packet transmission with configurable intervals, allowing QoS monitoring at appropriate frequencies for different service requirements without continuous overhead, thus balancing reliability with resource consumption
Solution Approach 2:
The patent allows different detection parameters, packet types, and configurations to be applied locally to different QoS flows based on their specific service requirements, rather than using a uniform detection approach for all flows, optimizing resource usage per flow

AI summary
Embodiments of this application provide a method, device, and system for detecting quality of service of a service, to detect quality of service of a service. The method includes: obtaining, by a packet sending device, detection indication information, where the detection indication information is used to instruct the packet sending device to detect quality of service of a service; and sending, by the packet sending device, a detection packet to a packet receiving device based on the detection indication information, where the detection packet is used to detect the quality of service of the service.
