Early QoS Notification for V2X Bearer Negotiation
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 vehicle-to-anything (V2X) applications, leading to suboptimal driving behaviors.
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 V2V communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If existing QoS determination schemes are used during bearer establishment, then the network can establish QoS bearers, but the process is slow and inefficient with no early notification of QoS changes
Solution Approach 1:
The network entity performs preliminary QoS assessment and sends early notification about available QoS classes to the UE before the actual bearer establishment is completed. This allows the UE to prepare appropriate driving behavior modifications in advance, reducing the overall time loss when QoS changes occur.
Solution Approach 2:
The patent implements a feedback mechanism where the network entity notifies the UE about QoS changes and the UE responds with confirmation or alternative QoS class proposals. This bidirectional communication accelerates the QoS negotiation process by providing real-time status updates and enabling faster decision-making.
2Productivity
If traditional QoS negotiation methods are used, then bearers can be established, but signaling overhead is high and latency increases
Solution Approach 1:
The patent extracts the QoS notification function from the traditional bearer establishment procedure, allowing the network to send QoS availability information independently of the complete bearer setup process. This separation reduces signaling overhead by eliminating redundant messages while maintaining V2X service establishment efficiency.
3Reliability
If QoS changes are not notified early to UEs, then the network maintains control, but V2X applications cannot modify driving behavior in time, reducing reliability
Solution Approach 1:
The network entity performs preliminary QoS assessment and sends early notification about available QoS classes to the UE before the actual bearer establishment is completed. This allows the UE to prepare appropriate driving behavior modifications in advance, reducing the overall time loss when QoS changes occur.
Solution Approach 2:
The patent implements a feedback mechanism where the network entity notifies the UE about QoS changes and the UE responds with confirmation or alternative QoS class proposals. This bidirectional communication accelerates the QoS negotiation process by providing real-time status updates and enabling faster decision-making.
