Burst-Level Uplink Monitoring for Accurate Service Flow Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating data transmission performance using packet-level monitoring are inadequate for burst-based service flows, leading to poor user experience, particularly in scenarios like video streaming where frame loss results in video freeze.
Innovation Solution
Implement burst monitoring by determining delays and error rates at the network device level for both uplink and downlink bursts, using specific time points in the communication protocol layers to accurately assess performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If packet-level monitoring is used to evaluate data transmission performance, then the monitoring granularity is fine, but the evaluation accuracy for burst-based service flows deteriorates
Solution Approach 1:
The patent segments the data transmission monitoring into two levels: packet-level monitoring for detailed analysis and burst-level monitoring for performance evaluation. By segmenting the monitoring scope, the system can accurately evaluate burst-based service flows while maintaining the ability to analyze individual packet performance, thus resolving the contradiction between evaluation accuracy and monitoring complexity.
Solution Approach 2:
The patent introduces a new dimension of monitoring at the burst level, complementing the existing packet-level monitoring. This dimensional change allows the system to evaluate performance metrics such as delay, packet loss, and throughput at the burst level, providing more accurate evaluation for burst-based service flows without sacrificing packet-level detail.
2Reliability
If packet-level monitoring is used, then individual packet performance can be monitored, but burst-based service flow performance evaluation deteriorates
Solution Approach 1:
The patent merges packet-level monitoring and burst-level monitoring into a unified monitoring framework. By combining both levels of monitoring, the system can simultaneously evaluate individual packet performance and burst-based service flow performance, achieving accurate evaluation of service flow reliability without losing packet-level insights.
Solution Approach 2:
The patent creates a universal monitoring mechanism that serves multiple functions: it can monitor individual packets for detailed analysis and aggregate burst information for performance evaluation. This multi-functionality allows the system to accurately evaluate service flow reliability while maintaining the ability to analyze packet-level performance.
3Loss of information
If data packet granularity monitoring is used, then transmission details are captured, but user experience evaluation accuracy deteriorates
Solution Approach 1:
The patent implements feedback mechanisms at both packet level and burst level. By collecting feedback from packet-level monitoring and aggregating it to burst level, the system can accurately evaluate user experience metrics such as video freeze and frame loss. The feedback loop allows the system to capture transmission details while providing accurate user experience evaluation.
Data Source
AI summary
A burst monitoring method is provided, wherein an uplink delay of an uplink burst that is between a terminal device and an access network device and that is determined by the access network device includes a first uplink delay from a first time to a second time, the first time is a grant time of the first data packet that arrives at a MAC layer of the terminal device in the uplink burst, and the second time is a sending time of the last data packet that is sent from a PDCP layer of the access network device in the uplink burst. In this way, a process of monitoring the uplink delay of the uplink burst between the terminal device and the access network device is implemented.
