V2X Interface Switching Configuration for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in ensuring seamless switching between PC5 and Uu interfaces in V2X communication, leading to potential service interruptions due to differences in resource usage and link quality, especially when switching between coverage areas or during channel changes.
Innovation Solution
A method and apparatus for continuous communication that determines the optimal interface or mode switching based on resource usage, link quality, and scenario information, configuring the new interface or mode before switching to ensure service continuity and reduce switching delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interface switching is performed between PC5 and Uu interfaces, then communication adaptability is improved, but service interruption risk increases
Solution Approach 1:
The patent applies preliminary action by performing configuration of the new interface or mode before actually switching from the current interface. The terminal determines switching criteria, configures the target interface/mode in advance, and only then performs the switching operation. This ensures that the new interface is ready to immediately take over communication, preventing service interruption during the transition between PC5 and Uu interfaces.
2Loss of time
If interface switching is performed quickly, then switching delay is reduced, but configuration completeness may be compromised
Solution Approach 1:
The patent resolves this contradiction by performing configuration actions in advance before the switching moment. The terminal completes all necessary configuration steps for the new interface or mode prior to executing the switch, ensuring both configuration completeness and minimal switching delay. The configuration includes determining switching criteria, preparing the target interface parameters, and validating readiness before actual switching occurs.

AI summary
This application provides a communication method, relates to the field of communication technologies, and can reduce a probability of service interruption in an interface or mode switching scenario. The method includes: continuously communicating in a first mode of a PC5 interface or over a Uu interface; determining to perform interface switching or mode switching; configuring an interface or mode to be switched to; and after the configuration is completed, switching from the first mode of the PC5 interface to the Uu interface for communication, or switching from the first mode of the PC5 interface to a second mode of the PC5 interface for communication, or switching from the Uu interface to the first mode of the PC5 interface for communication, or switching from the Uu interface to the second mode of the PC5 interface for communication.
