Embodiment Construction

[0072] The following first introduces a network architecture in an existing Internet of Vehicles technology in combination with related drawings, see figure 1 , the network architecture includes a traffic control unit (Traffic control unit, TCU) and a vehicle-mounted unit (On-board unit, OBU), where the OBU is set in the vehicle to send V2X messages, and the TCU is used as a server in the communication network. It is used to aggregate V2X messages and distribute V2X messages to related vehicles. In the ITS protocol, it is usually stipulated that the reporting frequency of V2X messages should not be lower than 10Hz, such as figure 1 As shown, taking 10Hz as an example, the OBU periodically sends V2X messages to the TCU every 100ms (as shown in the figure, periodically sends V2X message 1, V2X message 2, V2X message 3, V2X message 4, V2X message 5, V2X message 6. V2X message 7, V2X message 8, etc.). After receiving a large number of V2X messages sent by related vehicles in the...

Abstract

The invention discloses a message processing method, and a related device and system. The method comprises the following steps: obtaining a travelling state parameter of a first vehicle within a current period by a first device; judging whether the travelling state parameter of the first vehicle is greater than a preset threshold; when the travelling state parameter of the first vehicle is greaterthan the preset threshold, obtaining a first V2X message, and sending the first V2X message to a second device; and when the travelling state parameter of the first vehicle is smaller than or equal to the preset threshold, not sending the first V2X message to the second device. By implementation of the message processing method, the problem of overlarge uplink and downlink data traffic in the V2Xbusiness can be solved, and the influence and the network resource consumption of the network bandwidth can be reduced without reforming the public network.

Description

technical field [0001] The present application relates to the field of Internet of Vehicles communication, in particular to a message processing method, related equipment and system. Background technique [0002] The Internet of Vehicles refers to a huge interactive network composed of information such as vehicle location, speed, and route. The Internet of Vehicles technology V2X (Vehicle to X) is a communication technology between vehicles and other devices, including Vehicle to Infrastructure (V2I), Vehicle Communication with vehicles (Vehicle to Vehicle, V2V), vehicles and mobile devices (Vehicle to Nomadic devices, V2N), vehicles and pedestrians (Vehicle to Personal, V2P), etc. V2X-based intelligent transportation system (Intelligent Transport System, ITS) assisted driving technology (such as European standard ETSI-ITS, Chinese standard C-ITS) is a current research hotspot. Currently, the mainstream communication architecture of ITS is DSRC and LTE-V, but Both DSRC and ...
