Multi-Path QoS Profiles for Path-Specific Traffic Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-path communication systems fail to adapt Quality of Service (QoS) profiles to the varying characteristics of different communication paths, leading to inefficient traffic distribution and resource utilization.
Innovation Solution
Configure distinct QoS profiles for each communication path, allowing negotiation and adaptation based on the specific access technologies or protocol tunnels used, and implement packet detection rules and filters to enforce these profiles, ensuring efficient packet switching and scheduling.

Engineering Contradiction Analysis
1Adaptability or versatility
If a single QoS profile is used for all communication paths, then device complexity is reduced, but QoS adaptation to path-specific characteristics is lost
Solution Approach 1:
The patent segments the QoS profile configuration by communication path, allowing each path to have its own QoS profile tailored to its specific characteristics (e.g., 3GPP access, non-3GPP access, wireless, wired). This enables path-specific QoS adaptation while maintaining manageable complexity through structured configuration.
Solution Approach 2:
The patent applies local quality by configuring different QoS profiles for different communication paths based on their local characteristics. Each path receives QoS parameters (data rate, latency, error rate) optimized for its specific access technology and network conditions, rather than applying a uniform profile system-wide.
2Productivity
If QoS profiles are configured per communication path, then QoS adaptation to path characteristics is improved, but device complexity increases
Solution Approach 1:
The patent enables dynamic QoS profile selection and traffic distribution across communication paths based on current network conditions and path characteristics. The system can adaptively adjust traffic routing and QoS parameters in real-time, improving productivity while managing complexity through automated decision-making algorithms.
Solution Approach 2:
The patent changes QoS parameters (data rate, latency requirements, error tolerance) based on the specific characteristics of each communication path. By adjusting these parameters dynamically according to path performance and network conditions, the system optimizes traffic distribution efficiency without requiring manual configuration of complex profiles.
3Reliability
If traffic is offloaded to alternative paths when one path is loaded, then communication robustness is improved, but QoS consistency across paths becomes difficult to maintain
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple QoS profiles for different communication paths before traffic offloading is needed. When a path becomes congested or fails, the system can immediately switch to a pre-configured alternative path with an appropriate QoS profile, maintaining both robustness and QoS consistency without requiring complex real-time profile adaptation.

AI summary
Examples relate to methods, computer programs, and apparatuses for user equipment and for a core network component and for enabling Quality of Service, QoS, in a multi-path communication session. The method (10) for enabling Quality of Service, QoS, in a multi-path communication session between two communication nodes in a communication network (400), the multi-path communication session comprises at least first and second communication paths, comprises configuring (12) a first QoS profile, when setting up the first communication path and configuring (14) a second QoS profile, which is different from the first QoS profile, when setting up the second communication path.
