V2X Mobility Message Switching for Low-Latency Network Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately and efficiently transmitting and receiving messages, particularly in V2X communication scenarios, which are crucial for vehicle-to-everything interactions, due to varying mobility information and latency requirements.
Innovation Solution
A method is introduced where a network processes mobility information received from user equipment (UE) to determine the type of message transmission based on the similarity or difference in mobility information, converting it into object or event information, and optionally updating the mobility information based on predicted values, using specific thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network transmits mobility information frequently to ensure accuracy, then the reliability of position information is improved, but the latency and message overhead increase
Solution Approach 1:
The patent changes the parameter of message transmission by dynamically selecting between two message types (first type for same mobility information, second type for different mobility information) based on the change threshold. This parameter change allows the system to adapt transmission frequency to actual mobility needs, improving efficiency without sacrificing accuracy.
Solution Approach 2:
The patent introduces dynamic behavior in message transmission by comparing current mobility information with previous information and adjusting the message type accordingly. When mobility information changes exceed a threshold, the system transmits updated information (second type message); otherwise, it transmits unchanged information (first type message). This dynamic approach optimizes both accuracy and latency.
2Adaptability or versatility
If the network processes and converts mobility information into object or event information, then the relevance and usefulness of transmitted data is improved, but the processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining two message types with specific structures and purposes. The first message type carries unchanged mobility information, while the second message type carries converted object or event information. This preliminary classification framework simplifies the processing complexity by providing a clear decision path based on change thresholds.
Solution Approach 2:
The patent changes the information format parameter by converting mobility information into object or event information (second type message) when changes exceed the threshold. This parameter transformation enhances the versatility and relevance of transmitted data while maintaining manageable processing complexity through structured conversion rules.
3Loss of information
If the network transmits detailed mobility information for all UEs, then the completeness of information is improved, but the message overhead and system load increase
Solution Approach 1:
The patent extracts only the necessary mobility information for transmission by comparing current information with previous information. When changes exceed the threshold, only the updated second type message is transmitted; otherwise, the first type message with unchanged information is sent. This extraction approach reduces message overhead while maintaining information completeness where needed.
Solution Approach 2:
The patent applies partial action by selectively transmitting mobility information based on change thresholds rather than transmitting all information for all UEs continuously. This partial transmission strategy reduces overall message overhead while ensuring completeness is maintained when mobility changes occur.
