QoS Bearer Negotiation Using Early Notification for V2X Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing schemes for determining Quality of Service (QoS) classes between User Equipments (UEs) and networks during bearer establishment are slow and inefficient, lacking early notification of QoS changes that affect driving behavior in vehicle-to-anything (V2X) applications.
Innovation Solution
Introduce soft admission control and explicit notification schemes for next available QoS bearer information during bearer establishment, including early notifications and flexible QoS negotiation between UEs and network entities, such as MME in LTE and AMF in 5G, to facilitate faster and safer vehicle-to-vehicle communication.

Engineering Contradiction Analysis
1Productivity
If existing QoS determination schemes are used during bearer establishment, then the process is completed with standard procedures, but the negotiation is slow and inefficient with high latency
Solution Approach 1:
The network entity performs preliminary QoS assessment and prepares available QoS bearer information before the actual bearer establishment request. This preliminary action allows the network to have QoS options ready in advance, enabling faster negotiation when the UE requests bearer establishment, thus reducing the overall latency without compromising the standardization of the process.
Solution Approach 2:
The patent introduces an intermediate QoS negotiation mechanism where the network entity provides a list of available QoS bearers as a mediator between the UE's QoS requirements and the network's resource capabilities. This intermediary list enables efficient matching and selection, speeding up the bearer establishment process while maintaining procedural standardization.
2Reliability
If standard bearer establishment procedures are followed, then the process is standardized and manageable, but there is no early notification of QoS changes affecting driving behavior
Solution Approach 1:
The network entity provides feedback to the UE about available QoS bearers and potential QoS changes during the bearer establishment process. This feedback mechanism enables the UE to be informed early about QoS conditions, allowing driving behavior to be adapted proactively based on network capabilities, thus improving reliability without deviating from standardized procedures.
Solution Approach 2:
The network entity performs preliminary QoS assessment and prepares available QoS bearer information before the actual bearer establishment request. This preliminary action allows the network to have QoS options ready in advance, enabling faster negotiation when the UE requests bearer establishment, thus reducing the overall latency without compromising the standardization of the process.
3Adaptability or versatility
If QoS negotiation is performed cooperatively considering network conditions, then driving behavior can be optimized, but the message interaction and signaling overhead increase
Solution Approach 1:
The patent extracts the QoS negotiation essence into a standardized list of available QoS bearers that the network provides to the UE. This extraction allows the complex cooperative negotiation to be simplified into a structured information exchange, maintaining adaptability for driving behavior optimization while reducing signaling overhead through efficient information packaging.
Solution Approach 2:
The patent changes the negotiation parameters from detailed cooperative discussions to a structured QoS bearer list with key parameters. This parameter transformation enables the UE to efficiently evaluate network conditions and adapt driving behavior without extensive back-and-forth signaling, thus reducing complexity while maintaining versatility.
