QoS Mapping Framework for Wireless Traffic Xhaul Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face unnecessary long latency when integrating multiple networks of different types for end-to-end communication, particularly in wireless traffic xhauling scenarios, due to lack of visibility and scheduling alignment between sub-systems.
Innovation Solution
A Quality of Service (QoS) mapping framework that uses a Bandwidth Report (BWR) message to predict and schedule traffic across sub-systems, allowing early initiation of request-grant loops and reducing overall latency by aligning scheduling between transport and non-transport networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple networks are integrated for end-to-end communication, then network functionality and coverage are improved, but latency increases due to lack of scheduling alignment between sub-systems
Solution Approach 1:
The patent implements a QoS mapping framework that performs preliminary scheduling actions in the transport network based on bandwidth reports from the non-transport network. This allows the transport network to pre-allocate resources and prepare for upcoming traffic bursts before they actually occur, eliminating waiting time and achieving scheduling alignment between network sub-systems without increasing complexity
2Loss of time
If QoS mapping framework is implemented, then latency is reduced and QoS consistency is improved, but system complexity increases
Solution Approach 1:
The patent introduces a QoS mapping framework as an intermediary layer between the transport and non-transport networks. This framework translates QoS parameters between different network domains and enables coordinated scheduling without requiring complex modifications to the underlying network protocols. The framework acts as a mediator that simplifies the integration complexity while achieving latency reduction through standardized QoS mapping and bandwidth reporting mechanisms

AI summary
A quality of service framework for applications may be provided. First, a Bandwidth Report (BWR) message may be received from a first sub-system by a second sub-system. The BWR message may correspond to traffic to be received from the first sub-system by the second sub-system. Next, based on the BWR message, the second sub-system may schedule grants for the traffic to be received from the first sub-system. The second sub-system may then receive, from the first sub-system, the traffic. Then the second sub-system may transmit the traffic based on the scheduled grants.
