Edge Server Handover Logic for Vehicle Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dense region divisions, handover processing between edge servers is often wasted due to vehicles moving to another region before the completion of the handover process, leading to inefficiencies in data transfer.
Innovation Solution
An information processing system that performs handover processing only when a vehicle moves outside of its original region and an extended region, determined by specific rules or geographical distances, to minimize unnecessary data transfers between edge servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handover processing is performed frequently between edge servers when regions are densely divided, then service continuity for moving vehicles is improved, but data transfer waste increases due to vehicles moving to another region before handover completion
Solution Approach 1:
The system determines in advance whether handover processing is necessary by checking if the vehicle has moved outside both the original region and the extended region before initiating data transfer. This preliminary assessment prevents unnecessary handover processing for vehicles that have not actually left the service area, thereby reducing data transfer waste while maintaining service continuity for vehicles that do move away.
2Measurement precision
If region division is made dense to improve service precision, then service coverage is improved, but handover processing efficiency deteriorates due to increased frequency of unnecessary handovers
Solution Approach 1:
Before performing handover processing, the system preliminarily determines whether the vehicle has moved outside the extended region by checking position information against region boundaries. This preliminary check filters out unnecessary handover cases caused by dense region divisions, allowing the system to maintain precise service coverage while improving handover processing efficiency by avoiding redundant operations.
3Reliability
If handover processing is performed whenever a vehicle leaves a region, then service continuity is maintained, but processing waste increases when the vehicle moves to an adjacent region during the handover process
Solution Approach 1:
The system performs a preliminary determination of whether handover is necessary by checking if the vehicle position is outside both the original region and the extended region before initiating the handover process. This preliminary action prevents wasteful handover processing when vehicles move to adjacent regions during data transfer, reducing time waste while ensuring service continuity is maintained for vehicles that truly need handover.

AI summary
An information processing system includes: a first server associated with a first region, the first server including a first processor configured to output information concerning a predetermined service to a vehicle traveling in the first region; and the vehicle including a second processor, wherein the first processor is configured to perform handover processing for outputting information concerning the vehicle held by the first server to a second server associated with a second region adjacent to the first region when the vehicle moves from the first region to the second region in a case where the vehicle has moved to an outside of the first region and to an outside of an extended region obtained by extending the first region.
