Multi-Link QoS Reporting for Precise Packet Loss Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack a solution for accurately determining the quality of service (QoS) of multiple links in a multi-link scenario, which hinders the reliability of low-delay services.
Innovation Solution
A method and apparatus for generating and sending quality of service measurement reports that include link indication information and QoS information, such as the number of media access control service data units lost on each link, to enable accurate determination of QoS across multiple links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multi-link transmission is performed to reduce delay, then transmission speed is improved, but quality of service measurement capability deteriorates
Solution Approach 1:
The patent segments the quality of service measurement by link, introducing link indication information that identifies each link and reports quality of service parameters separately for each link. This allows precise measurement of QoS for each individual link in the multi-link transmission system, resolving the contradiction between multi-link transmission speed and QoS measurement precision.
2Loss of time
If multi-link transmission is used to reduce delay, then transmission time is improved, but reliability of service transmission deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the first station reports quality of service measurement results for each link back to the second station. This feedback enables the second station to identify which link has poor QoS and take corresponding actions, thereby improving service transmission reliability while maintaining the low delay benefits of multi-link transmission.
3Measurement precision
If quality of service information is reported for each link, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple quality of service measurement results into a single quality of service measurement report structure. The report includes link indication information identifying each link and corresponding quality of service parameters, combining what would otherwise be separate measurement processes into one integrated report that maintains precision while reducing operational complexity.
Data Source
AI summary
A method includes receiving quality of service requirement information including packet loss rate indication information. The packet loss rate indication information includes an index value and a reference number of service data packets. The reference number of service data packets indicates a reference measurement number for counting the packet loss rate. The index value includes one or more characters. The index value corresponds to an index item in a database. The index item in the database has a mapping relationship with an acceptable maximum packet loss rate in the database. The acceptable maximum packet loss rate includes two or more characters. A quantity of the one or more characters included in the index value is less than a quantity of the two or more characters included in the acceptable maximum packet loss rate. The method also includes determining quality of service requirement based on the quality of service requirement information.
