Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Internet of Vehicles (IoV) system, existing technologies face challenges in efficiently allocating transmission resources for vehicle terminals, particularly in preventing carrier resource abuse and ensuring quality of service (QoS) attributes, especially in mode 3 where network devices cannot effectively restrict carrier selection actions.
Innovation Solution
A method where a network device determines the QoS attributes of a terminal device, such as data transmission rate and reliability requirements, and allocates a transmission resource, including carrier resources, to ensure efficient data transmission between terminal devices, improving resource utilization and preventing resource conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle terminal uses sensing-based and reservation-based transmission manner in mode 4, then resource conflict probability is reduced, but network device cannot implement carrier selection restriction
Solution Approach 1:
The patent introduces a network device as an intermediary between terminal devices to implement carrier selection restriction. The network device receives carrier selection information from terminal devices and provides feedback to restrict carrier selection, thereby enabling control in mode 4 while maintaining the sensing-based transmission manner that reduces resource conflicts.
2Device complexity
If terminal device randomly selects resource from available transmission resource set, then implementation complexity is reduced, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the network device receives carrier selection information from terminal devices and provides feedback to guide resource selection. This feedback enables the network device to allocate resources more efficiently while terminal devices maintain relatively simple selection processes based on the received feedback information.
3Loss of time
If terminal device uses semi-static transmission manner, then resource re-selection probability is reduced, but adaptability to QoS changes deteriorates
Solution Approach 1:
The patent introduces dynamic carrier selection restriction through network device feedback. While terminal devices use semi-static transmission manners to reduce re-selection frequency, the network device dynamically adjusts carrier selection restrictions based on current network conditions and QoS requirements, enabling adaptability without increasing terminal device re-selection probability.
4Productivity
If network device allocates transmission resource according to QoS attribute, then resource allocation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments the resource allocation process into distinct functions: terminal devices determine QoS attributes and select carriers, while the network device receives this information and provides carrier selection restriction feedback. This segmentation allows efficient QoS-based resource allocation while distributing system complexity across different devices rather than concentrating it in one location.
