Embodiment approach

[0191] 1. The on-vehicle device may determine an uplink message sending strategy according to the sender of the first Internet of Vehicles message. Specifically, if the sender of the first IoV message is the RSU, the vehicle-mounted device determines the uplink message sending strategy as: sending the IOV message to the RSU, and instructs the RSU to forward the IOV message to the server. If the sender of the first Internet of Vehicles message is not a roadside unit, the on-vehicle device determines that the uplink message sending strategy is: sending the Internet of Vehicles message to the server in unicast form.

[0192] Correspondingly, the schematic diagram of the on-vehicle device sending the second Internet of Vehicles message to the server according to the uplink message sending policy may be as follows Figure 11A with 11B shown. Such as Figure 11A As shown, the sender of the first Internet of Vehicles message is the RSU, indicating that the vehicle-mounted device i...

Abstract

The present application discloses a message interaction method for the Internet of Vehicles and related devices, wherein the method includes: the server obtains the position information of the first roadside unit and the second roadside unit on the first road section, and the reference value of the density of roadside units, the first The first roadside unit and the second roadside unit are two adjacent roadside units, and the first road section is the road section between the first roadside unit and the second roadside unit; The reference value determines the density of roadside units on the first road section; the server determines the downlink message sending strategy according to the density of roadside units on the first road section; the server sends the first message to the first vehicle-mounted device according to the downlink message sending strategy In the Internet of Vehicles news, the first vehicle-mounted device is the vehicle-mounted device on the first road section. This scheme can avoid message duplication, message loss or long transmission delay.

Description

technical field [0001] The present application relates to the communication field of the Internet of Vehicles, and in particular to a message interaction method and related devices of the Internet of Vehicles. Background technique [0002] Vehicle to everything (V2X) communication refers to the communication technology that connects vehicles to everything. V2X can be called the Internet of Vehicles. V2X communication is a technology developed based on the Internet of Things. V2X communication is the foundation and key technology of smart cars, autonomous driving, and intelligent transportation systems. V2X communication includes four parts: 1) vehicle-to-network (V2N) communication, which refers to the communication between vehicle-mounted equipment and network equipment, which can be used to connect vehicle-mounted equipment to a server through a wireless network, and use the navigation, Application functions such as entertainment and anti-theft; 2) vehicle-to-vehicle (V2V...
