Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G V2X systems face limitations in message transmission range and require complex roaming interfaces for service provisioning, which hinders efficient vehicle communication services.
Innovation Solution
A 5G-based V2X system architecture with defined network slice structure and V2X application server (AS) provisioning information management, allowing third-party service providers to offer V2X services without relying on LTE V2X system roaming interfaces, and enabling 5G-specific services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If LTE-based V2X system is used, then service coverage is improved, but device complexity and roaming interface requirements increase
Solution Approach 1:
The patent extracts the V2X control function from the mobile network operator's infrastructure and relocates it to the vehicle terminal itself. This allows the terminal to autonomously select and switch between LTE and 5G networks without requiring complex roaming interfaces between operators, thereby maintaining wide service coverage while reducing system complexity.
Solution Approach 2:
The patent introduces a V2X control function as an intermediary layer between the terminal and the network infrastructure. This control function manages network selection and switching, enabling seamless operation across different network types (LTE and 5G) without requiring direct complex interfaces between network operators.
2Ease of operation
If LTE V2X roaming interfaces are used, then service provisioning is achieved, but system complexity and operator burden increase
Solution Approach 1:
The patent implements self-service by enabling the vehicle terminal to autonomously perform network selection and service provisioning through its integrated V2X control function. The terminal independently manages connectivity between LTE and 5G networks without requiring complex inter-operator roaming agreements, thereby simplifying service provisioning while reducing operator burden.
3Productivity
If 5G network slice structure is implemented, then service efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple network slice templates within the terminal's V2X control function before network connection is needed. These pre-configured slices correspond to different service types (e.g., safety-critical, infotainment), enabling the terminal to quickly select and activate appropriate slices without complex real-time decision-making, thereby improving service efficiency while managing complexity.
