Abstract

An IoV message exchange method performed by the server includes: obtaining position information of a first roadside unit, position information of a second roadside unit, and a roadside unit density reference value, the first roadside unit and the second roadside unit are on a first road section and are two adjacent roadside units, and the first road section is a road section between the first roadside unit and the second roadside unit; determining a density of roadside units on the first road section based on the position information and the roadside unit density reference value; determining a downlink message sending policy based on the density of the roadside units on the first road section; and sending the first IoV message to a first vehicle-mounted device according to the downlink message sending policy, the first vehicle-mounted device is a vehicle-mounted device on the first road section.

Claims21

Dependent claims

A method implemented by an Internet of vehicles (IoV) message exchange server and comprising:

obtaining first position information of a first roadside unit (RSU), second position information of a second RSU, and an RSU density reference value, wherein the first RSU and the second RSU are on a first road section and are adjacent to each other, wherein the first road section is between the first RSU and the second RSU, and wherein the RSU density reference value is a safe driving distance;
determining a density of RSUs on the first road section based on the first position information, the second position information, and the RSU density reference value;
determining a downlink message sending policy based on the density;
and
sending, according to the downlink message sending policy, a first IoV message to a first vehicle-mounted device on the first road section.

2 more elements
