Method and device for transmitting data in internet of vehicles system

A method for transmitting data in a Vehicle-to-Everything (V2X) system, comprising:

• establishing, by network equipment, a radio resource connection with a terminal device, the network equipment being network equipment containing a serving cell for the terminal device and the network equipment being deployed by a first operator;
• transmitting, by the network equipment, identity information of the terminal device to core network equipment for the core network equipment to authenticate and verify the terminal device according to the identity information of the terminal device;
• and
• transmitting, by the network equipment, information of a second operator to the terminal device when receiving information indicating successful authentication and verification from the core network equipment, the information of the second operator comprising at least one of identification information or frequency resource information.
