and step S204, the intelligent gateway receives a second data packet forwarded by the target vehicle through the target base station, and sends the second data packet to the cloud server under the condition that the target address corresponding to the second data packet is the cloud server, wherein the second data packet at least comprises driving feedback of the target vehicle in the target area based on the road condition information provided by the first data packet.
It should be noted that, with the development and application of the 5G technology, the automatic driving and the vehicle-road cooperation will be changed, but the global 5G network construction is the core network centralized construction, and the 5G base station accesses the transmission network with a longer distance and then reaches the core network for processing, so the whole service flow is longer, even if the edge computing unit is arranged, the signaling interaction still needs to be in the whole process, the whole time delay is still larger, and the time delay adopting the LTE technology is larger. It is generally accepted in the industry that automatic driving requires that the minimum delay of a communication network is below 10-20 milliseconds, the average value is less than 15 milliseconds, and the large delay cannot meet the requirement of cooperative automatic driving of a vehicle and a road, and may cause safety threats to the vehicle, passengers and pedestrians.
Fig. 3 shows a structure diagram of an automatic driving data transmission network in the related art at present, as shown in fig. 3, original data acquired by a camera and a radar in a target area are directly transmitted to a roadside preprocessing unit through an optical fiber/network cable, the roadside preprocessing unit processes the original data and transmits the processed data to an automatic driving cloud control platform in a cloud server through an optical fiber, the cloud control platform calculates and generates road fusion sensing data (road condition information) through a specific algorithm, transmits the road condition information to a core network, transmits the road condition information to a base station through a transmission network, and finally transmits the road fusion sensing data to a vehicle.
According to the automatic driving data transmission method, the first data packet sent by the cloud server can be obtained through the intelligent gateway, the second data packet is sent to the cloud server under the condition that the target address corresponding to the second data packet is the cloud server, the purpose that automatic driving data directly interact with the cloud server through the intelligent gateway to bypass the transmission of a core network and a transmission network is achieved, the technical effect of reducing network delay is achieved, and the technical problem that the data transmission rate is low due to the fact that the network communication delay is too long is solved.
It should be noted that, in the above method, the driving feedback of the target area includes, but is not limited to, whether the target vehicle is in error or warning after driving based on the road condition information, and whether the vehicle is off the route.
In some embodiments of the application, the first data packet may further include a driving decision determined by the cloud server according to the obtained traffic information, for example: the target vehicle determines whether to drive according to the driving decision provided by the cloud server.
The above steps S202 to S204 will be specifically explained by an embodiment.
In step S202, the intelligent gateway sends the first data packet to the target vehicle, which may be accomplished by: firstly, the intelligent gateway needs to encapsulate a first data packet and establish an association relation between the first data packet and address information to obtain an encapsulated first data packet; and sending the encapsulated first data packet to a target base station according to address information, wherein the address information at least comprises: the address of the target base station, the address of the target vehicle and the tunnel endpoint identification; and the target base station sends the received encapsulated first data packet to a target vehicle according to the address information.
In an alternative manner, the intelligent gateway may encapsulate the first data packet in a preset form according to the tunneling protocol.
Specifically, the cloud server sends a first data packet to the intelligent gateway, the intelligent gateway performs GTP (GPRS Tunneling Protocol) encapsulation in a payload form, associates a target base station address, a target vehicle address, and a tunnel endpoint identifier, and after encapsulation is completed, the intelligent gateway simulates a UPF (User Plane Function) to send to the target base station, and the target base station sends to the vehicle according to a normal 3GPP standard flow.
It can be understood that no interface is associated between the intelligent gateway and the core network, which ensures that the intelligent gateway directly transmits data to the cloud server instead of forwarding through the core network. Target vehicles, road condition information and the like are directly interacted with the cloud server through the target base station, a transmission network and a core network are not needed, special lines such as optical fibers or wavelength division can be adopted between the intelligent gateway and the cloud server, the overall network delay is greatly shortened by utilizing the advantage of low delay of an NR (noise reduction) air interface of the target base station, and the cooperative automatic driving operation of the vehicle and the road is well supported.
In some embodiments of the application, after receiving a second data packet sent by a target vehicle, the intelligent gateway determines whether a target address corresponding to the second data packet contains a cloud server address, and if the target address does not contain the cloud server address, determines that the data packet is not a data packet sent to a cloud server, and sends the second data packet to a core network through a transmission network.
Optionally, in a case that the second data packet is decapsulated, the intelligent gateway restores the decapsulated second data packet and then sends the decapsulated second data packet to the core network through the transport network.
It is understood that the core network is a 5G core network.
Specifically, the target vehicle sends data to the intelligent gateway through the target base station, the intelligent gateway conducts GTP decapsulation in a payload mode and then sends the data to the cloud server, and if the terminal accesses address information which does not contain the automatic driving cloud control platform, the GTP encapsulation is restored and sent to the core network or the GTP is directly sent to the 5G core network without decapsulation.
In some embodiments of the application, the intelligent gateway acquires a first data packet from the cloud server through a preset transmission line, wherein road condition information in the first data packet is determined by the cloud server through acquired image information and position information in a target area, and the image information and the position information are acquired by an image acquisition device on the road side, a radar device and a target vehicle in the target area.
In a practical application scenario, as shown in fig. 4, the image capturing device in the target area, for example: the camera and the radar device collect image information and position information of roads in a target area, the acquired image information and position information are transmitted to the roadside preprocessing unit through optical fibers, the roadside preprocessing unit carries out preprocessing and then transmits the image information and the position information to the automatic driving cloud control platform through the optical fibers, the cloud control platform generates road fusion sensing data through specific algorithm calculation, the road fusion sensing data are used for reflecting road condition information, (a first data packet), the first data packet is transmitted to the intelligent gateway through a preset transmission line, and then the intelligent gateway transmits the road fusion sensing data to a target vehicle through the 5G base station.
It can be understood that the sensing data is fused, the target vehicle, the road side camera and the radar device jointly acquire image position information, and the data used for reflecting road condition information is calculated and obtained by a cloud control platform in the cloud server.
In some embodiments of the present application, after receiving the access request sent by the target vehicle, the intelligent gateway further needs to perform validity verification on the identity information of the target vehicle included in the access request, and if the identity information passes the verification, the intelligent gateway receives the second data packet.
It should be noted that in an actual application scenario, the intelligent gateway and the base station are deployed in the same machine room, the 5G base station is also relatively close to the radar and the camera, and the automatic driving cloud control platform is generally deployed in a machine room near a park or selects a nearby cloud resource. Because the time delay of each 100km of the optical fiber is about 0.5ms, the time delay influence brought by the optical fiber in the whole system is small, and the processing and forwarding time delay of the 5G intelligent gateway is less than 0.1ms.
The method provided in the embodiment of the present application is implemented by, at a target base station, for example: the intelligent gateway is arranged on the side of the 5G base station, the intelligent gateway is not associated with any interface of a 5G core network, interaction such as fusion perception data (road condition information) of the vehicle-road cooperative automatic driving vehicle and the cloud server is directly transmitted locally through the 5G base station without passing through a transmission network and the core network, and meanwhile, the low-delay advantage of an NR (noise-reduction) air interface of the 5G base station is utilized, so that the communication network delay is greatly shortened, and the requirement of low-delay of the vehicle-road cooperative automatic driving is met.
It should be noted that, the 5G intelligent gateway may adopt a general server, has a built-in firewall function, and is low in cost.
