V2X Communication Mode Decision via Network Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing V2V communication mode switching methods rely solely on individual V2X UE decisions, leading to potential signal attenuation, network congestion, and service instability due to mismatched wireless transmission environments and excessive vehicle density.
Innovation Solution
An information processing method and device that involve a server receiving pre-configured information, obtaining communication mode decision information, and sending it to corresponding V2X UEs, considering network status, service quality, and traffic information to determine optimal communication modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If V2X UE decides communication mode independently, then device complexity is reduced, but reliability deteriorates due to signal attenuation and communication failure
Solution Approach 1:
The patent introduces the network side (network device or application server) as an intermediary to participate in communication mode decision-making. The network side collects information from multiple V2X UEs and makes coordinated mode selection decisions, acting as a mediator between individual UEs and the communication system to improve reliability while managing complexity centrally.
Solution Approach 2:
The patent implements a feedback mechanism where the network side continuously monitors communication status, vehicle density, and transmission environment, then adjusts communication mode decisions accordingly. This closed-loop feedback allows dynamic adaptation to changing conditions, improving reliability by responding to real-time system state.
2Ease of operation
If V2X UE determines communication mode alone, then ease of operation is improved, but harmful factors increase due to signaling storms and network congestion
Solution Approach 1:
The network side serves as a coordinator that collects communication status information from multiple UEs and manages mode selection to prevent harmful effects. By centralizing the decision-making process, the system avoids the signaling storms and congestion that would result from each UE independently attempting mode switching.
Solution Approach 2:
The patent applies preliminary action by having the network side proactively collect and analyze communication status information before mode switching occurs. The network device predicts potential conflicts and pre-coordinates communication modes to avoid signaling storms and network congestion before they happen.
3Adaptability or versatility
If individual UE selects communication mode, then adaptability to local conditions is improved, but service quality deteriorates due to mismatched transmission environments
Solution Approach 1:
The patent merges individual UE adaptability with network-wide coordination by combining local transmission environment information with network status information. The network side integrates multiple UE reports and makes unified mode selection decisions that consider both local conditions and overall network state, achieving a balance between adaptability and service quality.
