Resource Control Server for V2X Congestion Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication systems face inefficiencies in congestion control due to lack of direct knowledge of transmission interference among vehicles, leading to unreliable communication and system capacity issues, particularly in distributed congestion control scenarios, and increased complexity and cost with centralized congestion control solutions.
Innovation Solution
Implementing a resource control server that provides congestion management instructions to user equipment via a secondary network, using commercial mobile broadband networks to communicate congestion information and adjust transmission patterns, thereby overcoming the limitations of both distributed and centralized congestion control methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If distributed congestion control is implemented where each car measures its local environment, then the complexity level is low, but the efficiency of congestion control is limited and unreliable
Solution Approach 1:
The patent introduces a centralized congestion control entity that acts as an intermediary between vehicles and the network. This entity collects congestion information from multiple sources including direct measurements from vehicles, network measurements, and historical data, then processes this information centrally to generate congestion control decisions. This intermediary approach resolves the contradiction by providing reliable global congestion control without requiring complex distributed coordination among vehicles.
2Reliability
If centralized congestion control is implemented as part of base stations, then congestion control efficiency improves, but the complexity and cost increase due to deployment in multitude of eNBs
Solution Approach 1:
The patent extracts the centralized congestion control functionality from the base station infrastructure and places it in a separate, dedicated congestion control entity. This extraction allows the congestion control function to be implemented independently of the base station deployment, reducing the complexity burden on the wireless access network. The congestion control entity can be deployed as a standalone server or cloud-based service, eliminating the need to deploy complex congestion control functionality in every eNB while maintaining efficient centralized control.
3Reliability
If centralized congestion control is coordinated among eNBs controlled by same and different mobile operators, then system-wide congestion management improves, but the cost and complexity increase
Solution Approach 1:
The patent merges the congestion control functionality across multiple base stations and mobile operators into a single centralized congestion control entity. This consolidation allows the system to achieve system-wide congestion management by collecting and processing congestion information from all eNBs in one location, eliminating the need for complex inter-operator coordination protocols. The unified congestion control entity can make global decisions based on aggregate congestion data without requiring each eNB to independently coordinate with others, significantly reducing coordination complexity while maintaining system-wide effectiveness.
