V2X Session Continuity Across Multi-Network Automotive Edge Computing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AECC system architectures lack mechanisms for initiating and supporting vehicle-to-everything (V2X) data session and service continuity at the application level, particularly when vehicles move between different communication networks, and they do not adequately support V2X data session and service continuity across multiple radio access technologies.
Innovation Solution
The introduction of a Mobility Service Provider (MSP) center server that manages session and service registration and continuity for moving vehicles, utilizing a distributed computing architecture with MSP edge servers to ensure seamless data session and service continuity across various networks, including cellular and non-cellular networks, by monitoring network status and initiating background data transfer sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current AECC system architecture is used, then basic edge computing services are provided, but V2X data session and service continuity cannot be ensured when vehicles move between networks
Solution Approach 1:
The system segments the V2X service management into two distinct components: an MSP center server that handles session management and mobility coordination, and multiple MSP edge servers that provide local computing services. This segmentation allows the center server to maintain service continuity while edge servers provide network-specific services, resolving the contradiction between reliability and adaptability across multiple networks.
Solution Approach 2:
The MSP center server acts as an intermediary between vehicles and multiple MSP edge servers across different networks. It coordinates session establishment, handover, and service continuity, enabling vehicles to seamlessly move between networks while maintaining reliable V2X data sessions. This intermediary role resolves the contradiction by providing centralized coordination for multi-network adaptability while ensuring service reliability.
2Quantity of substance
If cellular networks are used for V2X communication, then mobile connectivity is provided, but big data capacity growth between vehicles and cloud is not fully ensured
Solution Approach 1:
The system transitions from a single centralized cloud architecture to a multi-dimensional distributed edge computing architecture. By deploying multiple MSP edge servers at different network edges and coordinating them through the center server, the system increases both data capacity (quantity) and data transfer speed by providing parallel data paths and reducing distances between vehicles and computing resources.
Solution Approach 2:
The system merges cellular and non-cellular networks into a unified V2X communication framework managed by the MSP center server. This integration allows vehicles to utilize multiple network types simultaneously, increasing overall data capacity while maintaining high transfer speeds through optimal path selection and load distribution across merged networks.
3Area of stationary object
If multiple edge servers are deployed across different networks, then network coverage is improved, but mechanisms for session continuity across edge servers are lacking
Solution Approach 1:
The system extracts session management functionality from individual edge servers and centralizes it in the MSP center server. This extraction allows multiple edge servers to be deployed across different networks to expand coverage, while the center server handles the complexity of session coordination, handover, and continuity, preventing the system from becoming unmanageably complex.
Solution Approach 2:
The MSP center server provides universal session management capabilities that work across all MSP edge servers regardless of which network they are deployed on. This multi-functional approach allows the same session management mechanisms to handle services across cellular, non-cellular, and hybrid networks, expanding coverage without proportionally increasing complexity.
