Route-Based Connectivity QoS Allocation Across Mobile Operators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing connectivity quality of service to vehicles are inefficient due to lack of dynamism in network slicing, especially when multiple mobile network operators are required, and are unable to meet location-based requirements of moving vehicles.
Innovation Solution
A system and method involving a service management server that allocates communication resources from multiple mobile network operators based on predefined vehicle routes, managing and reserving connectivity quality of service by interfacing with these operators, and providing feedback to user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional network slicing is used to ensure link quality, then service reliability is improved, but the system lacks dynamism to meet location-based requirements of moving vehicles
Solution Approach 1:
The patent implements dynamic network slicing that adapts to the vehicle's location and movement. The system continuously updates slice configurations based on real-time location information, allowing the network to dynamically allocate resources and adjust parameters as the vehicle moves through different geographic areas, thereby maintaining both reliability and adaptability
Solution Approach 2:
The system performs preliminary network slicing configuration based on predicted vehicle routes and location-based service requirements. By pre-establishing network slices along anticipated paths and preparing resource allocations in advance, the system ensures seamless connectivity as the vehicle moves, avoiding service interruptions while maintaining dynamic adaptability
2Reliability
If prediction-based QoS is used, then service availability is improved, but control over specific link quality requirements is lost
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors actual link quality metrics and compares them against required QoS parameters. Based on this feedback, the network dynamically adjusts resource allocation, modulation schemes, and other transmission parameters to maintain precise control over link quality while ensuring service availability through prediction-based pre-configuration
3Device complexity
If connectivity resources are allocated without route information, then system complexity is reduced, but connectivity reliability along the route deteriorates
Solution Approach 1:
The system receives route information in advance and performs preliminary network slicing configuration and resource reservation along the entire predicted path. By pre-establishing connectivity resources at all necessary locations before the vehicle travels, the system ensures reliable connectivity without requiring complex real-time resource allocation decisions during movement
Solution Approach 2:
The patent divides the vehicle's route into multiple geographic segments or cells, with each segment having its own dedicated network slice and resource allocation. This segmentation allows the system to manage complexity by handling smaller, localized resource allocations independently while ensuring end-to-end connectivity reliability across the entire route through coordinated slice management
