AI Technical Summary
In existing technologies, V2X message transmission consumes a lot of network resources and has a long latency. In particular, in communication technologies based on the Uu interface, an independent unicast connection needs to be established for each vehicle, resulting in resource waste and increased transmission latency.
The network device receives V2X messages sent by the terminal and broadcasts them directly within the service range of the V2X broadcast service, avoiding the need to establish independent unicast connections with other terminals. It utilizes the broadcast capability of the network device to send the messages to all terminals within the service range at once.
It reduces intermediate steps in the V2X message transmission process, lowers network resource consumption and transmission latency, and improves message transmission efficiency, as well as the immediacy and security of information transmission.
