Information transmission method based on internet of vehicles and related equipment thereof

Abstract

The invention provides an information transmission method based on Internet of Vehicles and related equipment thereof, and aims to enable a first terminal to generate a BSM smoothly, enable a second terminal to receive the BSM from the first terminal, and determine the position of the first terminal based on the BSM. The method comprises the steps that a first terminal acquires an encrypted coordinate value of the first terminal; the first terminal generates a first coordinate value and a second coordinate value according to the encrypted coordinate value; the first terminal generates a basicsecurity message BSM according to the first coordinate value and the second coordinate value, the BSM comprises a required field and an optional field, the required field is used for indicating the first coordinate value, the optional field is used for indicating the second coordinate value, and the first coordinate value is located in a value range corresponding to the required field; the first terminal sends the BSM to the second terminal; the second terminal determines an encrypted coordinate value according to the first coordinate value indicated by the required field and the second coordinate value indicated by the optional field; and the second terminal decrypts the encrypted coordinate value 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
