Area-Based Traffic Support Control Under Edge Resource Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving systems of the coordinative type face network congestion and high load on management servers due to resource limitations in edge servers, which are not installed on an application-by-application basis and have restricted calculation and communication resources.
Innovation Solution
A server device connected to base stations generates support information independently for each support-provided area, using a condition determination unit to set resource limits and a resource calculation unit to allocate calculation and communication resources, ensuring they do not exceed total available limits, thereby preventing network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If edge servers are used as management servers to reduce delay, then response speed is improved, but network congestion occurs and server load increases due to limited calculation and communication resources
Solution Approach 1:
The patent segments the support information generation process by area, with each edge server independently generating support information for its own support-provided area. This segmentation prevents network congestion by localizing data processing and reducing the need for centralized resource allocation, thereby maintaining fast response speeds while preserving network capacity.
2Adaptability or versatility
If multiple applications share edge servers, then resource utilization is improved, but calculation and communication resources are restricted
Solution Approach 1:
The patent implements local quality by having each edge server independently determine and reserve resources for its own support-provided area based on local traffic conditions and area situation information. This allows each server to optimize resource allocation locally without being constrained by global resource sharing limitations, effectively increasing available resources while maintaining multi-application compatibility.
3Area of stationary object
If support information is generated for multiple support-provided areas, then service coverage is improved, but resource allocation becomes complex and exceeds total resource limits
Solution Approach 1:
The patent segments resource allocation by support-provided area, with each edge server independently managing resources for its designated area. The resource calculation unit calculates and reserves resources for each area separately based on support information generation conditions, preventing allocation complexity while expanding service coverage to multiple areas through this modular approach.
4Adaptability or versatility
If support information generation conditions are determined dynamically, then adaptability to area situations is improved, but calculation load on the server increases
Solution Approach 1:
The patent applies partial action by having the condition determination unit determine support information generation conditions only for areas where they are actually needed, based on area situation information. This selective approach provides dynamic adaptability to changing conditions while avoiding excessive calculation load by not processing all areas uniformly.

AI summary
A server device includes a support information generation unit, a condition determination unit, and a resource calculation unit. The support information generation unit generates support information for each support-provided area using information from a communication terminal. The condition determination unit determines a support information generation condition being a condition concerning the support information to be generated by the support information generation unit, based on area situation information representing a situation thereof. The resource calculation unit calculates, based on the support information generation condition, amounts of calculation resource and amounts of communication resource of each support-provided area not to cause a sum of the amounts of calculation resource required in each support-provided area and a sum of the amounts of communication resource for use between the server device and a mobile terminal, to exceed total calculation/communication resource upper limit values available in all the support-provided areas.
