1. A road side unit (RSU) device for vehicle-to-everything (V2X) service, the RSU device comprising:
a processor; and
a memory operatively coupled with the processor and configured to store instructions that, when executed by the processor, cause the RSU device to perform functions comprising:
transmitting, to a V2X server, a message for configuring an RSU subscription area for a V2X service to request the V2X server to forward a first V2X message of a first V2X device when a publishing area of the first V2X device overlaps with the RSU subscription area, the publishing area of the first V2X device being an area in which the first V2X device transmits the first V2X message, wherein the first V2X device directly communicates with the V2X server based on a first communication protocol but does not communicate with the RSU device;
receiving, from the V2X server, the first V2X message published by the first V2X device associated with the RSU subscription area, wherein the first V2X message of the first V2X device is received by the V2X server and then is delivered by the V2X server to the RSU device, and a part or all of the RSU subscription area overlaps with the publishing area of the first V2X device;
converting the first V2X message conforming to the first communication protocol into a second V2X message conforming to a second communication protocol; and
transmitting, to a second V2X device, the second V2X message, wherein the second V2X device directly communicates with the RSU device based on the second communication protocol but does not communicate with the V2X server.
