Vehicle Wireless Resource Allocation by Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems face issues where allocated wireless resources are not utilizable due to the requirement for the communication apparatus to be positioned at a specific location within the base station area, leading to inefficiencies and potential communication failures.
Innovation Solution
The proposed vehicle communication system allocates not only wireless resources but also specific locations to the vehicle communication apparatus for each time period, ensuring that the vehicle can utilize the allocated resources by synchronizing the location with the allocated wireless resource, preventing situations where the resource is not usable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless resource allocation is performed for each base station area, then wireless resource management becomes simplified and efficient, but the communication apparatus is required to be positioned at a specific location within the base station area, leading to situations where allocated resources cannot be utilized
Solution Approach 1:
The patent segments the base station area into multiple location zones (first location, second location, third location) with different communication characteristics. Each zone is independently analyzed for communication efficiency and available frequency range, allowing the system to match wireless resources to specific location segments rather than treating the entire base station area as a single unit.
Solution Approach 2:
The patent applies local quality by recognizing that different locations within the base station area have different communication properties (communication efficiency, available frequency range). The system tailors wireless resource allocation to match these local characteristics, allocating resources based on the specific location where the communication apparatus will operate, thereby ensuring resource usability while maintaining allocation efficiency.
2Adaptability or versatility
If the same number of communication apparatuses are deployed in the same base station area, then resource allocation appears uniform, but communication efficiency and available frequency range vary by location, causing inconsistent actual performance
Solution Approach 1:
The patent resolves this contradiction by applying local quality - it maintains uniform allocation policies at the base station level while adapting the specific resource assignments to local communication conditions at each location zone. This ensures both uniformity in allocation approach and consistency in actual communication performance.
Solution Approach 2:
The system changes parameters (communication efficiency, available frequency range) based on location to determine appropriate wireless resource allocation. By adjusting allocation decisions according to location-specific parameters, the system achieves consistent communication performance across different locations while maintaining a structured allocation framework.
3Loss of time
If wireless resources are allocated without considering specific location requirements, then allocation process becomes faster and simpler, but the communication apparatus may not be able to utilize the allocated resources when not positioned at the assumed location
Solution Approach 1:
The patent applies preliminary action by determining the expected location of the communication apparatus in advance of resource allocation. The system evaluates communication characteristics at each potential location beforehand, then uses this pre-analyzed information to make rapid allocation decisions that ensure resource usability. This eliminates the need for complex real-time location verification while maintaining high reliability.

AI summary
A vehicle communication system includes a vehicle communication apparatus (21,121) for a vehicle (5, 5A, 5B), a management apparatus (4, 4A, 4C) managing wireless resources, and a request transmitter transmitting a resource allocation request requesting the allocation of a location resource and a wireless resource by time to the management apparatus. The vehicle communication apparatus includes a vehicle transmitter (213), a vehicle receiver (214), and a vehicle communication controller (215). The management apparatus includes a management apparatus receiver, an allocator, and a management apparatus transmitter. The vehicle receiver receives an allocation result, and the vehicle communication controller controls the vehicle transmitter and the vehicle receiver based on the allocation result received by the vehicle receiver.
