MESSAGE PROCESSING METHOD, IN-VEHICLE TERMINAL, AND BASE STATION
First Claim
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; 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, 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).

Abstract
The present disclosure provides a message processing method, an in-vehicle terminal, and a base station. The method executed by a first in-vehicle terminal includes: first, generating a safety message, where the safety message includes message content and a message type; then, determining, according to the message content and the message type, a priority value corresponding to the safety message; finally, sending, 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 a VDC PHY layer, so that a base station and/or a second in-vehicle terminal receive/receives the safety message, and the first in-vehicle terminal can send, under a preset delay requirement, the safety message to another in-vehicle terminal in a distance range that needs to be covered by the safety message.

6. A message processing method, the method comprising:
-
receiving, by a base station, a safety message by using a cellular physical (cellular PHY) layer and/or a vehicle direct communication physical (VDC PHY) layer; triggering, by the base station, a Media Access Control (MAC) layer to identify the safety message and send the safety message to an Intelligent Transportation System Protocol (ITSP) layer; and triggering, by the base station, the ITSP layer to determine, according to a message type in the safety message and location information in the safety message, whether to forward the safety message, and determine a forwarding area or a forwarding server address corresponding to a case in which the safety message needs to be forwarded. - View Dependent Claims (7, 8, 9, 10, 11)

12. An in-vehicle terminal, comprising:
-
a memory storing a program; and a processor, configured to execute the program, the program comprising instructions that, when executed by the processor, cause the in-vehicle terminal to; generate a safety message, wherein the safety message comprises message content and a message type; determine, according to the message content and the message type, a priority value corresponding to the safety message; and send, 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 in-vehicle terminal each pre-establish a vehicle direct communication-radio bearer (VDC-RB). - View Dependent Claims (13, 14, 15, 16, 17)
