Network Delay Processing with Transport-Layer Phase Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to accurately measure and adjust for network delays and jitters in wireless communication systems, particularly affecting services with strict delay requirements like Extended Reality (XR) and multimedia, as they do not account for the impact of transport layer delays on application layer performance.
Innovation Solution
A method and apparatus for processing network delays and jitters by receiving and measuring various phases of transmission delays and jitters, including UE-UPF, UPF-access network element, and AS-UPF interactions, and adjusting radio resource configurations based on these measurements to optimize service transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing technologies are used to measure network delay, then measurement is performed at application layer only, but transport layer delay impact on application layer performance is not accounted for
Solution Approach 1:
The patent segments the network delay measurement into multiple phases: application layer delay (first delay), transport layer delay (second delay including N3 and N9 transmission), and core network delay (third delay). Each phase is measured and reported separately to the access network element, enabling comprehensive delay accounting without information loss.
2Productivity
If radio resource configuration is adjusted based on incomplete delay information, then service transmission can be optimized partially, but optimal resource allocation cannot be achieved
Solution Approach 1:
The patent implements a feedback mechanism where the access network element receives delay information from multiple phases (application layer, transport layer, core network) and uses this comprehensive feedback to dynamically adjust radio resource configuration. This enables optimal resource allocation by considering the complete delay picture rather than partial information.
3Ease of operation
If delay measurement is performed without considering multiple transmission phases, then measurement process is simple, but accurate delay attribution to specific phases is not achieved
Solution Approach 1:
The patent segments the network delay measurement into multiple phases: application layer delay (first delay), transport layer delay (second delay including N3 and N9 transmission), and core network delay (third delay). Each phase is measured and reported separately to the access network element, enabling comprehensive delay accounting without information loss.
