An information transmission method, system, terminal, communication device, and computer storage medium based on Internet of Vehicles

Abstract

This application provides an information transmission method based on the Internet of Vehicles and related equipment, which can enable the first terminal to successfully generate a BSM, so that the second terminal can receive the BSM from the first terminal, and determine the location of the first terminal based on the BSM. The method of the present application includes: the first terminal obtains the encrypted coordinate value of the first terminal; the first terminal generates the first coordinate value and the second coordinate value according to the encrypted coordinate value; the first terminal generates the first coordinate value and the second coordinate value according to the first coordinate value and the second coordinate value The two-coordinate value generates a basic safety message BSM. The BSM includes a mandatory field and an optional field. The mandatory field is used to indicate the first coordinate value, and the optional field is used to indicate the second coordinate value. The first coordinate value corresponds to the required field. range of values; the first terminal sends a BSM to the second terminal; the second terminal determines the encrypted coordinate value according to the first coordinate value indicated by the mandatory field and the second coordinate value indicated by the optional field; The encrypted coordinate value is decrypted to obtain the decrypted coordinate value of the first terminal.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for determining a location based on the Internet of Vehicles and related equipment. Background technique [0002] In the vehicle to everything (V2X) communication technology, a certain vehicle can notify the surrounding vehicles and roadside equipment of its location information by broadcasting basic safety messages (BSM), so that the surrounding The vehicle and the roadside equipment determine the position of the vehicle based on the BSM. [0003] The following takes the first terminal (a vehicle-mounted device) and the second terminal (another vehicle-mounted device or a certain roadside device) in the IoV communication system as an example for illustration. Before the first terminal broadcasts the BSM, the first terminal will make the BSM carry a mandatory field for indicating the coordinate value of the first terminal (for example, the latitud...

AI Technical Summary

Problems solved by technology

After the first terminal encrypts its own coordinate value, the encrypted coordinate value may be outside the preset value range, then the first terminal will stop the encoding operation, resulting in the failure to generate BSM, so the second terminal cannot receive BSM of the first terminal, the position of the first terminal cannot be determined
