Access Node Virtual Terminal for V2X Message Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular communication systems face challenges in detecting and processing Vehicle-to-Everything (V2X) messages within cellular communication networks, as conventional access nodes are not equipped to receive these messages due to different communication protocols used by vehicular devices, leading to inefficiencies in data exchange and increased operational complexity.
Innovation Solution
The implementation of a virtual terminal device within access nodes that supports V2X protocols, allowing the capture and forwarding of V2X messages to application servers via a network, thereby reducing the need for dedicated capturing devices and simplifying system design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional access nodes are used in cellular communication networks, then the existing network infrastructure can be maintained, but the nodes cannot detect or process V2X messages due to protocol incompatibility
Solution Approach 1:
The access node is enhanced to perform multiple functions: it operates as a conventional cellular base station while simultaneously functioning as a V2X message receiver. The receiving unit is configured to detect V2X messages from vehicular devices using V2X communication protocols, enabling the access node to handle both traditional cellular traffic and V2X communications without requiring separate dedicated receiving devices.
2Reliability
If dedicated capturing devices are deployed to receive V2X messages, then V2X message detection capability is improved, but device complexity and system cost increase
Solution Approach 1:
The patent combines the V2X message receiving function with the existing cellular base station infrastructure. Instead of deploying separate dedicated capturing devices, the access node integrates V2X reception capabilities into its existing architecture. The receiving unit is configured within the access node to detect V2X messages while the transmitting unit forwards them to application servers, eliminating the need for additional standalone receiving hardware.
Solution Approach 2:
The access node is designed to perform multiple functions simultaneously: conventional cellular base station operations and V2X message reception. This multi-functional design allows the same infrastructure to serve both traditional mobile communication and vehicular communication needs, reducing overall system complexity and eliminating redundant hardware.
3Productivity
If access nodes are configured to forward V2X messages to application servers, then data exchange efficiency is improved, but operational complexity increases
Solution Approach 1:
The access node autonomously performs V2X message forwarding based on pre-configured parameters. The transmitting unit is configured to automatically forward detected V2X messages to application servers using pre-established forwarding parameters, eliminating the need for manual intervention or complex real-time configuration. This self-service mechanism simplifies operation while maintaining efficient data exchange.
