QoS Change Notification Mapping for V2X Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks, particularly in V2X applications, face challenges in providing fine-granular in-advance quality of service (QoS) change notifications, leading to potential safety issues due to coarse-granular notifications that do not account for individual user equipment (UE) variations in QoS requirements and configurations.
Innovation Solution
Implementing a mechanism where radio network nodes receive and associate potential QoS change notifications with in-advance QoS prediction notifications based on specific location, required QoS, and configuration or subscription information of the UE, enabling fine-granular notifications tailored to individual recipients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coarse-granular QoS change notifications are used, then the system complexity is reduced and ease of operation is improved, but the reliability deteriorates due to false notifications that do not account for individual UE variations
Solution Approach 1:
The patent segments the QoS notification mechanism by introducing a mapping function that divides the notification process into distinct stages: receiving coarse-granular PQCN from the second radio network node, mapping it to fine-granular IQN using UE-specific parameters, and delivering to the appropriate application. This segmentation allows the system to maintain simple network-side notifications while achieving precise UE-specific delivery through the mapping function that considers individual UE configurations, QoS requirements, and location data.
Solution Approach 2:
The first radio network node acts as an intermediary between the second radio network node and the UE. It receives the PQCN, processes it through a mapping function that incorporates UE-specific information, and generates the appropriate IQN for delivery. This intermediary role allows the system to maintain simple network-side notifications while achieving precise UE-specific delivery without requiring complex changes at the network core level.
2Reliability
If fine-granular QoS change notifications are implemented, then the reliability is improved by accounting for individual UE variations, but the device complexity increases due to mapping requirements
Solution Approach 1:
The mapping function operates autonomously at the first radio network node, automatically matching received PQCN with appropriate UE configurations and QoS parameters without requiring manual intervention. The system self-manages the complexity of fine-granular notifications by maintaining mappings between PQCN and UE-specific parameters, allowing accurate delivery while keeping the operation transparent to both the network and UEs.
3Reliability
If proactive QoS change notifications are sent, then the reliability is improved for safety-critical applications, but the loss of information increases due to potential false alerts
Solution Approach 1:
The system performs preliminary matching and validation before generating IQN notifications. The mapping function pre-processes the received PQCN by comparing it against stored UE configurations, QoS parameters, and location data to determine which UEs should receive notifications. This preliminary action ensures that only UEs with actual QoS changes receive alerts, reducing false notifications while maintaining proactive warning capabilities for safety-critical applications.

AI summary
A first radio network node for assisting application adjustment is configured to receive a potential quality of service change notification (PQCN) from a second radio network; associate the PQCN with an in-advance quality of service prediction notification (IQN) recipient based on a mapping between a request for an IQN from an IQN recipient and an existing PQCN subscription, wherein the mapping is established based on a location, a required quality of service (QoS) and at least one of: configuration information associated with the IQN recipient or subscription information associated with the IQN recipient; and send an IQN to the IQN recipient for assisting the application adjustment.
