Vehicle-road cooperative management method, MEC server, terminal and system

Abstract

The embodiment of the invention provides a vehicle-road cooperative management method, an MEC server, a terminal and a system, relates to the field of intelligent transportation, and aims to avoid information leakage caused by access of an illegal terminal to a vehicle-road cooperative management system and enhance the safety of the vehicle-road cooperative management system. The method comprisesthe steps that a terminal acquires data information, wherein the data information comprises signature information, traffic information and attribute information of the terminal, the traffic information is used for indicating road conditions related to the terminal, the signature information is used for verifying the legality of the terminal, and the attribute information is used for indicating thetype of the terminal; the terminal sends the data information to an MEC server; the MEC server receives the data information sent by the terminal; the MEC server judges whether the terminal is legalor not according to the signature information; if the terminal is legal, the MEC server determines a traffic optimization strategy according to the traffic information; and the terminal receives the traffic optimization strategy sent by the MEC server. The method is used for optimizing the intelligent traffic.

Description

technical field [0001] The present invention relates to the field of intelligent transportation, in particular to a vehicle-road collaborative management method, an MEC server, a terminal and a system. Background technique [0002] In recent years, the intelligent transportation industry has developed rapidly. With the application and continuous improvement of intelligent transportation systems, although the efficiency of urban traffic management has been greatly improved, the application of the Internet of Vehicles system has also caused a large number of safety hazards. [0003] In the intelligent transportation scenario, the vehicle-mounted equipment, road-side equipment and network equipment in the traditional intelligent transportation system usually use cellular mobile network communication for data transmission. When the intelligent transportation system uses the cellular mobile network for communication, if the cellular mobile network is not protected, illegal device...

AI Technical Summary

Problems solved by technology

When the intelligent transportation system uses the cellular mobile network for communication, if the cellular mobile network is not protected, illegal devices can access the cellular mobile network by pretending to be a legitimate device, occupy the network resources of the intelligent transportation system, and intercept the information of the intelligent transportation system. The data information of each device in the network; illegal devices can also control the operation of traffic lights and other equipment through access to the cellular mobile network, disrupting the normal traffic order and affecting the normal operation of traffic
