Description

[0002] Vehicle to Everything (V2X) communication technology can be subdivided into vehicle-to-vehicle communication (V2V), vehicle-to-infrastructure communication (V2I), vehicle-to-pedestrian communication (V2P), vehicle-to-network communication (V2N), etc. from the perspective of communication scenarios. From the perspective of communication technology implementation, V2X can be divided into dedicated short-range communication DSRC (Dedicated Short Range Communication) technology based on the IEEE802.11 standard and C-V2X (Cellular Vehicle to Everything) technology based on the cellular mobile communication system.
[0003] In V2I communication, based on local 5G mobile edge computing (5G MEC), the in-vehicle terminal can transfer services with high latency requirements to local edge computing nodes through base stations. The base station diverts data packets through the sinking user plane function (UPF), so that the Internet of Vehicles data is processed on the mobile edge computing server, and the non-Internet of Vehicles data is sent to the core network for processing. Finally, the edge computing results are returned to the in-vehicle terminal through the base station. MEC is generally deployed on the road side or in the edge room of the operator's metropolitan area network. The main delay is the wireless access network air interface delay and the MEC edge processing delay. Based on the 5G air interface, it can meet the 10ms level real-time perception analysis processing feedback requirements.

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0044] refer to Figure 1 , Figure 1 The present invention is a flow chart of a method for offloading traffic from a base station of an Internet of Vehicles based on 5G MEC, the method comprising:
[0045] S101, performing mobile edge computing according to a vehicle terminal signal diverted by a first base station arranged on the roadside;
[0046] S102, based on the vehicle position information obtained by mobile edge computing, determine whether the distance between the vehicle and the first base station is not less than the distance between the vehicle and the second base station; if so, send a base station switching command to the first base station; wherein the second base station is set downstream of the first base station along the vehicle's driving direction.
[0047] It should be noted that the S0N in this specification does not represent the order of the vehicle network base station offloading method based on 5G MEC. Figure 2 The present invention specifically describes the vehicle networking base station offloading method based on 5G MEC.
[0048] Step S101: Perform mobile edge computing based on the vehicle terminal signal diverted by the first base station set on the roadside.
[0049] In this embodiment, mobile edge computing is performed based on the vehicle terminal signal diverted by the first base station set on the roadside, including: receiving the vehicle terminal signal diverted by the first base station set on the roadside; calculating the position relationship of the vehicle relative to the first base station and the second base station according to the real-time position of the vehicle in the vehicle terminal signal, and obtaining the vehicle position information. It should be noted that in the process of performing mobile edge computing, the driving direction of the vehicle relative to the first base station can be determined according to the real-time position of the vehicle, that is, it can be determined whether the vehicle is driving from the service range of the first base station to the service range of the second base station located downstream of the first base station.
[0050] Before performing mobile edge computing based on the vehicle terminal signal diverted by the first base station set on the roadside, it includes: when the vehicle is traveling along the driving direction, the vehicle data signal within the service range of the first base station is reported to the first base station; the first base station determines whether the vehicle data signal complies with the Internet of Vehicles service according to the Internet of Vehicles service; if so, the vehicle terminal signal is diverted to the mobile edge computing MEC server for mobile edge computing based on the source of the vehicle data signal, and the non-terminal signal is diverted to the basic network.
[0051] Step S102, based on the vehicle position information obtained by mobile edge computing, determine whether the distance between the vehicle and the first base station is not less than the distance between the vehicle and the second base station; if so, send a base station switching command to the first base station; wherein the second base station is set downstream of the first base station along the vehicle's driving direction.
[0052] It should be noted that when a vehicle travels from the service range of the first base station to the service range of the second base station located downstream of the first base station, the vehicle position information obtained by mobile edge computing based on the real-time position of the vehicle reported by the vehicle in real time is judged. When the vehicle position information indicates that the vehicle is located in the middle of the first base station and the second base station, or the vehicle is located between the first base station and the second base station and close to the second base station, a base station switching command is sent to the first base station so that the first base station can send the base station switching command to the corresponding vehicle for base station switching, thereby controlling the switching of roadside base stations and ensuring the continuity and stability of the Internet of Vehicles service.
[0053] In this embodiment, since, in actual application, there may be multiple vehicles within the service range of the first base station, when sending a base station switching command to the first base station, it includes: sending a base station switching command corresponding to the vehicle to the first base station based on the vehicle identity information contained in the vehicle terminal signal.
[0054] It can be seen from the above embodiments that by performing mobile edge computing on the vehicle terminal signal diverted by the first base station, the MEC server can be used to perform mobile edge computing on services with higher latency requirements, so as to migrate the work to a place closer to the vehicle terminal or user end, reduce the impact of site bandwidth limitations, and respond to vehicle terminal requests in real time to achieve switching between high-speed vehicles and communication base stations, improve the switching success rate, and ensure the continuity and stability of communication between vehicles and base stations.
[0055] refer to Figure 3 , Figure 3 The present invention is a flow chart of a method for offloading traffic from a base station of an Internet of Vehicles based on 5G MEC, the method comprising:
[0056] S201, determining the data type of the vehicle data signal sent by the vehicle within the service range according to the Internet of Vehicles service;
[0057] S202, diverting the vehicle data signal to a mobile edge computing MEC server or a basic network based on the data type;
[0058] S203, receiving the base station switching command returned by the MEC server, and sending it to the corresponding vehicle.
[0059] It should be noted that S0N in this specification does not represent the order of the vehicle network base station offloading method based on 5G MEC. The vehicle network base station offloading method based on 5G MEC of the present invention is described in detail below.
[0060] Step S201: determining the data type of the vehicle data signal sent by the vehicle within the service range according to the Internet of Vehicles service.
[0061] In this embodiment, the data type of a vehicle data signal sent by a vehicle within the service range is determined based on the Internet of Vehicles service, including: receiving a vehicle data signal sent by a vehicle within the service range; identifying the vehicle data signal, and verifying whether it is an Internet of Vehicles service based on the vehicle identity information contained in the vehicle data signal; if the vehicle data signal is an Internet of Vehicles service, dividing the vehicle data signal into a vehicle-mounted terminal signal and a non-terminal signal based on the data source information contained in the vehicle data signal to obtain the data type.
[0062] It should be noted that the vehicle data signal includes vehicle identity information, data source, and real-time location of the vehicle. The vehicle needs to activate the Internet of Vehicles service in advance, and associate the corresponding service with the vehicle identity information corresponding to the vehicle, so that when identifying the vehicle data signal, it can be verified whether the corresponding Internet of Vehicles service is activated in advance based on the vehicle identity information contained in the vehicle data signal, so as to determine whether the vehicle data signal needs to be diverted, so as to facilitate vehicle screening and avoid unnecessary diversion and mobile edge computing of vehicle data signals uploaded by vehicles that have not activated the Internet of Vehicles service.
[0063] Step S202: Divert the vehicle data signal to a mobile edge computing MEC server or a basic network based on the data type.
[0064] In this embodiment, the vehicle data signal is diverted to the mobile edge computing MEC server or the basic network based on the data type, including: diverting the vehicle terminal signal to the MEC server and diverting the non-terminal signal to the basic network according to the data type. It should be noted that the basic network is the operator's basic network, commonly known as the big network.
[0065] It should be noted that before the vehicle terminal signal is diverted to the MEC server, it is necessary to perform security verification on the vehicle terminal signal diverted to the MEC server based on the firewall to prevent abnormal data signals from entering the MEC server and to prevent malicious attacks from others from causing abnormalities in the mobile edge computing results of the MEC server.
[0066] Step S203: Receive the base station switching command returned by the MEC server and send it to the corresponding vehicle.
[0067] It can be seen from the above embodiments that the vehicle data signal uploaded by the vehicle is used to determine whether the vehicle has activated the Internet of Vehicles service, so as to avoid unnecessary diversion and mobile edge computing of the vehicle data signal uploaded by the vehicle that has not activated the Internet of Vehicles service, and further determine whether the vehicle data signal that has activated the Internet of Vehicles service is a vehicle-mounted terminal signal based on the data source, and divert the vehicle-mounted terminal signal to the MEC server, and divert the non-vehicle signal to the large network, so as to divert the vehicle data signal to reduce the transmission delay, realize local diversion of data traffic, and alleviate the data transmission pressure of the core network, thereby improving the network data processing efficiency and meeting the vertical industry's requirements for ultra-low latency, ultra-high bandwidth and security of the network; and then perform mobile edge computing on the diverted vehicle terminal through the MEC server to realize the switching between high-speed vehicles and communication base stations, and ensure the continuity and stability of communication between vehicles and base stations.

[0074] Step S302, executing a base station switching command to disconnect from the first base station and establish a connection with a second base station; wherein the second base station is arranged downstream of the first base station along the driving direction of the vehicle.
[0075] In this embodiment, establishing a connection with the second base station includes: sending a communication request to the second base station; the second base station performing security verification on the communication request; if the verification is successful, establishing a communication connection with the second base station.
[0076] It can be seen from the above embodiments that the vehicle data signal is uploaded through the vehicle-mounted terminal to facilitate the subsequent Internet of Vehicles business verification of the vehicle data signal uploaded by the vehicle-mounted terminal, and the vehicle data signal that has passed the Internet of Vehicles business verification is diverted to reduce the transmission delay, realize local diversion of data traffic, and alleviate the data transmission pressure of the core network, thereby improving the network data processing efficiency and meeting the vertical industry's requirements for ultra-low latency, ultra-high bandwidth and security of the network; then, mobile edge computing is performed on the vehicle terminal signal diverted to the MEC server to facilitate the subsequent continuous and stable switching of the communication between the high-speed vehicle and the base station; finally, the vehicle-mounted terminal receives the base station switching command issued by the MEC server and returned through the first base station, and executes it to realize the communication switching between the high-speed vehicle and the base station, improve the switching success rate, and ensure the continuity and stability of the communication between the vehicle and the base station.
