Network Delay Measurement for 5G QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring average packet delays in 5G NR networks are inefficient as they either overload terminals or lack precision, particularly for delay-sensitive services like real gaming and interactive services, due to the need for additional data transmission and uncertainty in delay calculations across network components.
Innovation Solution
A method and apparatus for measuring average downlink transmission data unit delay by monitoring arrival and departure times of data units within a network assembly, generating information on these times, and transmitting it to a network analysis entity, allowing for precise delay calculation without additional data transmission to terminals, specifically focusing on successful deliveries in RLC acknowledge mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional packet delay measurement methods are used in 5G NR networks, then delay data can be collected, but terminals become overloaded and additional data transmission is required
Solution Approach 1:
The patent introduces a measuring device deployed in the network (at the gNB or core network side) as an intermediary to perform delay measurements. This measuring device acts as a mediator that monitors packet delays without requiring terminal involvement, thereby eliminating terminal overload while maintaining measurement precision through network-side monitoring capabilities
Solution Approach 2:
The measurement function is extracted from the terminal and relocated to the network side. By taking out the delay measurement capability from the terminal device and implementing it in the network infrastructure, the patent eliminates the need for terminals to perform additional processing and data transmission, thus resolving the terminal overload issue while preserving measurement accuracy
2Measurement precision
If packet delay measurements are performed across network components, then delay data is obtained, but uncertainty in delay calculations increases
Solution Approach 1:
The patent implements feedback mechanisms where the measuring device continuously monitors packet delays and provides feedback information to the network. This feedback loop enables the system to adjust and refine delay measurements in real-time, reducing uncertainty and improving both the precision and reliability of delay calculations by continuously validating measurements against actual network conditions
Solution Approach 2:
The measuring device performs preliminary actions by pre-configuring measurement parameters and establishing monitoring points before actual delay measurements are taken. This preliminary setup ensures that measurements are conducted under controlled conditions with known parameters, reducing uncertainty in the delay calculation process and improving measurement reliability
3Measurement precision
If representative packet delay measurements are implemented, then quality of service monitoring improves, but terminal load and connection impact increase
Solution Approach 1:
A network-side measuring device serves as an intermediary that collects representative packet delay measurements without involving terminals. This intermediary approach maintains measurement representativeness for QoS monitoring while completely avoiding terminal load, as the measuring device independently performs all measurement functions using network-available information
Solution Approach 2:
The network infrastructure provides self-service by implementing its own delay measurement capability through the measuring device. Instead of requiring terminals to assist in measurements, the network independently performs delay monitoring using its own resources and capabilities, thereby maintaining measurement quality while preserving terminal efficiency
