1. A message processing method, the method comprising:
generating, by a first in-vehicle terminal, a safety message, wherein the safety message comprises message content and a message type;
determining, by the first in-vehicle terminal according to the message content and the message type, a priority value corresponding to the safety message;
sending, by the first in-vehicle terminal according to the priority value corresponding to the safety message, the safety message by using a vehicle direct communication physical (VDC PHY) layer or separately by using a cellular physical (cellular PHY) layer and the VDC PHY layer, so that a base station and/or a second in-vehicle terminal receive/receives the safety message;
wherein the base station and the first in-vehicle terminal each pre-establish a vehicle direct communication-radio bearer (VDC-RB);
wherein after generating, by the first in-vehicle terminal, the safety message, and before sending, by the first in-vehicle terminal according to the priority value corresponding to the safety message, the safety message by using the VDC PHY layer or separately by using the cellular PHY layer and the VDC PHY layer, the method further comprises:
adding, by the first in-vehicle terminal, obtained location information and speed information to the safety message by using an Intelligent Transportation System Protocol (ITSP) layer; and
transparently transmitting, by the first in-vehicle terminal, the safety message from the ITSP layer to a Media Access Control (MAC) layer by using a Packet Data Convergence Protocol layer (PDCP) layer and a Radio Link Control layer (RLC) layer; and
sending, by the first in-vehicle terminal according to the priority value corresponding to the safety message, the safety message by using a vehicle direct communication physical VDC PHY layer or separately by using a cellular physical cellular PHY layer and the VDC PHY layer comprises:
triggering, by the first in-vehicle terminal, the MAC layer to send, according to the location information, the speed information, and the priority value corresponding to the safety message, the safety message by using the VDC PHY layer or separately by using the cellular PHY layer and the VDC PHY layer.
