V2X Local E2E Path Configuration Module for QoS Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G V2X communication architectures face challenges in providing ultra-low latency and high reliability due to delays and QoS fluctuations across multiple domains, particularly in establishing end-to-end paths without coordinated information exchange between backhaul and access links, which affects the quality of service and performance.
Innovation Solution
A configuration module that selects data radio bearers per quality of service flow based on inter-node information from source, target, and radio access network nodes, initiating a radio resource communication connection configuration to establish a local end-to-end path, ensuring homogeneous QoS treatment across the path by negotiating and filtering DRBs to account for backhaul conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a local E2E path is established without coordinated information exchange between backhaul and access links, then the setup process is simpler and faster, but QoS treatment becomes non-uniform and performance degrades
Solution Approach 1:
The patent merges the backhaul and access link information exchange by introducing a configuration module that collects inter-node information from both domains and coordinates DRB selection across the entire E2E path, ensuring uniform QoS treatment while maintaining a streamlined establishment process
Solution Approach 2:
The configuration module acts as an intermediary between backhaul and access links, facilitating coordinated information exchange about DRB configurations and QoS parameters to ensure consistent QoS treatment across the local E2E path without requiring complex multi-domain interactions
2Reliability
If multiple layers and domains are involved in V2X communication, then network control and management are enhanced, but latency increases and E2E performance guarantees become difficult to provide
Solution Approach 1:
The patent segments the V2X communication architecture by introducing a local E2E path that operates independently within the RAN domain, isolating time-critical V2X traffic from the core network and reducing latency while maintaining network control through the configuration module
Solution Approach 2:
The configuration module performs preliminary actions by pre-configuring DRBs and establishing QoS parameters before V2X traffic flows, ensuring that the local E2E path is ready to immediately handle time-critical communications without requiring real-time coordination across multiple domains
3Productivity
If DRB selection is made without considering backhaul conditions, then the selection process is faster and simpler, but bottleneck links degrade the achieved performance
Solution Approach 1:
The configuration module implements feedback by collecting inter-node information about backhaul conditions and using this information to make informed DRB selection decisions, ensuring that selected DRBs are compatible with backhaul capacity and avoiding bottleneck links that would degrade performance

AI summary
The present invention relates to a configuration module allowing to establish a local end-to- end (E2E) path connecting at least one source node and at least one target node via at least one radio access network (RAN) node. The configuration module is configured to select data radio bearers (DRBs) per quality of service (QoS) flow based on inter-node information from 5 the at least one source node, the at least one target node, the at least one RAN node and all other nodes involved in establishing the local E2E path, and is also configured to initiate, after selecting the DRBs per QoS flow, a radio resource communication (RRC) connection configuration using an identification (ID) of the local E2E path to be established. Thereby, a localized traffic between the at least one source node and the at least one target node can 10 be exchanged with QoS guarantees.
