Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X technologies primarily focus on vehicle safety and vehicle-to-infrastructure communication, lacking support for diverse user groups such as pedestrians and electronic devices, and do not efficiently facilitate multicast services.
Innovation Solution
A V2X device and server system that enables determining service areas, generating logical channels, and managing subscriptions for multicast services, allowing vehicles and other devices to communicate and provide services like video streaming through a V2X server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X technology focuses on vehicle safety and vehicle-to-infrastructure communication, then communication reliability between vehicles and infrastructure is improved, but support for diverse user groups such as pedestrians and electronic devices deteriorates
Solution Approach 1:
The patent applies universality by designing the V2X communication system to serve multiple user types (vehicles, pedestrians, electronic devices) through a unified communication framework. The system uses universal service areas and logical channels that can accommodate different device categories, enabling one system to perform multiple functions rather than requiring separate systems for each user type.
Solution Approach 2:
The patent segments the communication service into different categories (first category for vehicles, second category for other devices) with specific logical channels for each. This segmentation allows tailored communication parameters for different user groups while maintaining overall system unity, resolving the contradiction between reliability for vehicles and versatility for diverse users.
2Productivity
If traditional V2X communication protocols are used, then vehicle-to-vehicle communication efficiency is improved, but multicast service support for diverse devices deteriorates
Solution Approach 1:
The patent introduces dynamic service area determination and logical channel selection based on device category and service type. The system can dynamically adjust communication parameters, service areas, and channel allocations to optimize efficiency for vehicle-to-vehicle communication while simultaneously supporting multicast services for diverse devices, rather than using fixed protocols.
3Area of stationary object
If service areas are broadly defined to include all users, then service coverage is improved, but service management complexity deteriorates
Solution Approach 1:
The patent segments service areas into category-specific regions (first service area for vehicles, second service area for other devices) with distinct logical channels for each. This segmentation enables broad overall coverage while simplifying management by allowing independent configuration and control of service parameters for each device category, rather than managing all devices uniformly.
Data Source
AI summary
Provided are a vehicle-to-everything (V2X) device and a V2X server for a multicast service. The V2X device determines a service area for a multicast service and generates a first logical channel for requesting subscription of the multicast service. The V2X device transmits, to the V2X server, a service support message including information about the service area and the first logical channel.
