V2X Location Group Updates Using Event-Triggered Vehicle Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating location-based groups in V2X networks fail to provide real-time updates on vehicles moving in or out of specific areas, especially in dynamic scenarios, leading to inefficient data management and increased resource consumption.
Innovation Solution
A system and method involving a location management server that receives subscription requests from a VAL server to monitor and notify about vehicles moving in or out of specific location areas, using criteria such as geographic location, reference UE information, and triggering events like time since last report or distance traveled, to manage dynamic or static location areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time monitoring of vehicle movements in location-based groups is implemented, then the accuracy and timeliness of location updates is improved, but the resource consumption and data intensity increases
Solution Approach 1:
The system implements event-triggered feedback mechanisms where vehicles report location changes only when specific conditions are met (entering/exiting location areas, distance thresholds, time intervals). This selective feedback approach maintains accurate location tracking while significantly reducing unnecessary data transmissions and resource consumption compared to continuous reporting.
Solution Approach 2:
The patent applies partial action by monitoring only relevant location changes that meet predefined criteria rather than continuously tracking all vehicle movements. The system performs location updates selectively based on triggering events, achieving sufficient accuracy for V2X applications while minimizing data intensity and energy usage.
2Loss of information
If continuous location updates are performed for all vehicles, then the real-time information availability is improved, but the network load and data processing complexity increases
Solution Approach 1:
The system extracts and reports only the essential location change information that meets predefined triggering conditions, rather than transmitting complete continuous location data for all vehicles. This selective extraction reduces network load and simplifies data processing while maintaining the necessary information for location-based group management.
Solution Approach 2:
The patent segments location monitoring into discrete event-based reports rather than continuous streams. By dividing the monitoring task into distinct triggering events (area entry, area exit, distance threshold, time interval), the system reduces overall data volume and processing complexity while maintaining real-time awareness of significant location changes.
3Loss of energy
If event-triggered location reporting is implemented, then the data efficiency is improved, but the system complexity increases
Solution Approach 1:
The system dynamically adjusts reporting behavior based on predefined triggering conditions rather than using static continuous reporting. The event-triggered mechanism allows the system to adapt its data transmission rate according to actual vehicle movement patterns and location changes, improving data efficiency while the complexity is managed through standardized event criteria.

AI summary
A system and method for updating location-based group in network by location management server are provided. The method includes receiving a location area monitoring subscription request from vertical application layer (VAL) server to subscribe for notification for at least one vehicle-to-everything (V2X) user equipment (UE) moving in or moving out of a specific location area associated with a group, sending a location area monitoring subscription response to the VAL server in response to successful authorization of the VAL server, detecting at least one V2X UE moving in or moving out of the specific location area associated with the group based on the subscription, and sending a location area monitoring notification to the VAL server including the triggering event and information about the at least one V2X UE moving in or moving out of specific location area associated with group.
