Terminal Access Layer Configuration for IoV D2D Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Internet of Vehicles (IoV) system lacks an effective management mechanism for terminal-to-terminal connections at the access layer, particularly in V2X LTE and NR systems, which hinders efficient direct communication between vehicles.
Innovation Solution
A method where a first terminal sends an access layer configuration parameter to a second terminal, enabling the second terminal to configure its access layer parameters for communication, specifically utilizing layers like SDAP, PDCP, RLC, MAC, or PHY, to establish and manage direct Device-to-Device (D2D) communication.

Engineering Contradiction Analysis
1Productivity
If direct terminal-to-terminal communication is implemented in IoV systems, then spectral efficiency and transmission delay are improved, but the lack of access layer connection management mechanism causes communication reliability to deteriorate
Solution Approach 1:
The patent introduces an access layer connection management mechanism that acts as an intermediary between terminals. The first terminal sends access layer configuration parameters to the second terminal through a structured message exchange process, enabling reliable direct communication without base station involvement while maintaining communication quality through standardized parameter configuration.
2Reliability
If access layer connection management is added to IoV systems, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The patent segments the connection management function into specific access layer configuration parameters that are independently configurable. By dividing the management mechanism into discrete parameter elements (first access layer configuration parameter, second access layer configuration parameter), the system achieves reliable connection management while keeping each component simple and manageable.
3Ease of operation
If terminals configure access layer parameters autonomously, then ease of operation is improved, but communication compatibility may deteriorate
Solution Approach 1:
The patent creates a universal access layer configuration mechanism where standardized parameter structures can be applied across different terminal types and communication scenarios. The first terminal and second terminal use the same configuration message format and parameter definitions, enabling autonomous configuration while ensuring broad compatibility across the IoV system.
Data Source
AI summary
A terminal connection method includes that: a first terminal sends a first message to a second terminal, the first message including a first access layer configuration parameter, and the first access layer configuration parameter being used by the second terminal to configure a parameter of an access layer to communicate with the first terminal.
