In the present exemplary embodiment, a communication method is first provided, and fig. 1 schematically illustrates a schematic block diagram of a flow of a communication method according to some embodiments of the present invention. Referring to fig. 1, the communication method includes the steps of:
step S110, receiving a data packet sent by a first terminal to a second terminal;
step S120, determining whether the data packet is in a V2X standard format of the Internet of vehicles, and determining whether the second terminal can receive the data packet in the V2X standard format;
step S130, if the data packet is determined to be the data packet in the V2X standard format and the second terminal cannot receive the data packet in the V2X standard format, analyzing the data packet according to a V2X standard protocol to acquire data in the data packet;
step S140, packing the data according to a predetermined data format, and sending the packed data to the second terminal.
According to the communication method in the exemplary embodiment, on one hand, the data packet in the V2X standard format is parsed and repackaged by using the preset data format, and is sent to the second terminal which is not equipped with the V2X standard format, so that the communication between the vehicle which is not equipped with the V2X equipment and the vehicle which is equipped with the V2X equipment can be realized, and the application range of the communication of the vehicle V2X is expanded; on the other hand, the communication method can decouple implementation of the V2X technology from hardware communication devices, thereby facilitating wider use of the V2X technology.
Next, the communication method of the present exemplary embodiment will be further explained.
Referring to fig. 1, in step S110, a data packet transmitted from a first terminal to a second terminal is received.
In some example embodiments of the present invention, the third party platform receives a communication request of the first terminal, verifies user information of the first terminal, and receives a data packet sent by the first terminal to the second terminal after the verification is passed. In the present example embodiment, the first terminal and the second terminal may be a vehicle equipped with a V2X device or a vehicle not equipped with a V2X device.
It should be noted that the third party platform end may be a cloud end, and a software stack of the V2X standard is deployed in the cloud end, and includes a service layer and an application layer. As shown in fig. 2, fig. 2 schematically illustrates a V2X software stack architecture diagram according to some embodiments of the present invention, the left half is a united states standard, and the right half is a european standard, and unless otherwise specified, all the V2X software stacks mentioned in this specification are united states standards. The communication protocol below the network and transport layer mainly defines the underlying communication mechanism, and has no relation with the data or message content, so the implementation of the cloud in this example embodiment does not specify the contents below the network and transport layer.
In step S120, it is determined whether the data packet is a data packet of the V2X standard format for the internet of vehicles, and it is determined whether the second terminal can receive the data packet of the V2X standard format.
In some example embodiments of the present invention, when receiving a packet sent by the first terminal, the service layer on the third party platform detects whether the packet is a packet in the V2X standard format, for example, the packet is unwrapped using the V2X standard format, if unwrapped, the packet is determined to be a packet based on the V2X protocol, and if not, the packet is determined to be a packet in the predetermined data format. The predetermined data format refers to other data formats which are deployed at the third-party platform end and can realize the invention besides the V2X standard format.
It should be noted that after determining the format of the data packet transmitted by the first terminal, it is necessary to continuously determine whether the second terminal can receive the data packet in the V2X standard format. And the service layer of the V2X software stack at the third platform end sends a test request to the second terminal, receives a return value corresponding to the test request, and judges whether the data format of the return value is the V2X standard format. If the data format of the return value is the V2X standard format, determining that the second terminal is equipped with a V2X device and can receive the data packet of the V2X standard format; if it is not the V2X standard format or no return value is received, it is determined that the second terminal equipment does not have a V2X device and cannot receive the data packet in the V2X standard format.
In step S130, if it is determined that the data packet is the data packet in the V2X standard format and the second terminal cannot receive the data packet in the V2X standard format, the data packet is parsed according to the V2X standard protocol, and the data in the data packet is obtained.
In some example embodiments of the present invention, when the determination result is the first mode, that is, when it is determined that the first terminal transmits the data packet in the V2X standard format and the second terminal cannot receive the data packet in the V2X standard format, the data packet in the V2X standard format needs to be processed to enable the second terminal to receive and read the data transmitted by the first terminal. And the service layer at the third-party platform end analyzes the data packet according to the V2X standard protocol to enable the data packet to become ordinary data.
As shown in fig. 3, fig. 3 schematically illustrates a communication diagram between a vehicle equipped with V2X and a vehicle not equipped with V2X, in step S310, a User ID corresponding to a User1 vehicle is matched at a cloud service layer, that is, a User1, and after the request verification of the User1 is passed, a data packet sent from the User1 vehicle to a User2 vehicle is received, and it is detected whether the data packet is in a V2X standard format; in step S320, determining that the data packet is in the V2X standard format, parsing the data packet according to the V2X standard protocol to make the data packet become normal data and sending the normal data to the application layer; in step S330, after receiving the common data sent by the service layer, the application layer in the cloud matches the User ID, i.e., User2, corresponding to the User2 vehicle end, adds data related to User1 and User2 to the common data to generate new data, and sends a test request according to the User2 to detect whether the vehicle end of the User2 can receive a data packet in the V2X standard format; in step S340, when it is determined that the User2 car end cannot receive the data packet in the V2X standard format, repackaging the new data according to the predetermined data format, sending the processed data packet in the predetermined data format to the User2 car end by the cloud end according to the User2, displaying the playing data through an HMI (Human Machine Interface), and completing the communication from the User1 car end to the User2 car end.
In step S140, the data is packaged according to a predetermined data format, and the packaged data is sent to the second terminal.
In some exemplary embodiments of the present invention, the service layer at the third platform parses the data packet sent by the first terminal according to the V2X standard format to generate normal data, sends the data to the application layer to repackage the data according to a predetermined data format, that is, a data format that can be recognized by the second terminal, sends the data packet with the predetermined data format to the second terminal, and completes the communication from the first terminal to the second terminal.
In some example embodiments of the present invention, when the determination result is the second mode, that is, when it is determined that the first terminal transmits a data packet that is not in the V2X standard format and the second terminal can receive the data packet in the V2X standard format, the data packet in the predetermined data format needs to be processed to enable the second terminal to receive and read the data transmitted by the first terminal. And analyzing the data packet at a service layer of the third-party platform end according to a preset data format to enable the data packet to become common data. The data is sent to an application layer to be repackaged according to the V2X standard format, and the data package of the V2X standard format is sent to the second terminal, so that the communication from the first terminal to the second terminal is completed.
As shown in fig. 4, fig. 4 schematically illustrates a schematic diagram of a vehicle not equipped with V2X communicating with a vehicle equipped with V2X, in accordance with some embodiments of the present invention. In step S410, after the request verification of the User1 is passed by matching the User ID corresponding to the User1 vehicle end, that is, the User1, in the cloud service layer, receiving a data packet sent from the User1 vehicle end to the User2 vehicle end, and detecting whether the data packet is in the V2X standard format; in step S420, determining that the data packet is not in the V2X standard format, parsing the data packet according to a predetermined data format to change the data packet into normal data and sending the normal data to the application layer; in step S430, after receiving the common data sent by the service layer, the application layer in the cloud matches the User ID, i.e., User2, corresponding to the User2 vehicle end, adds data related to User1 and User2 to the common data to generate new data, and sends a test request according to the User2 to detect whether the vehicle end of the User2 can receive a data packet in the V2X standard format; in step S440, when it is determined that the User2 car can receive the data packet in the V2X standard format, the data is repackaged according to the V2X standard format, and the cloud sends the processed data packet in the V2X standard format to the User2 car according to the User2, thereby completing the communication from the User1 car to the User2 car.
In some exemplary embodiments of the present invention, when the determination result is in the third mode, that is, when it is determined that the first terminal sends the data packet in the V2X standard format and the second terminal can receive the data packet in the V2X standard format, the second terminal may process the data packet in the V2X standard format by itself without the assistance of the third party platform, so that the data packet is transparently transmitted, that is, transparently transmitted to the second terminal without processing, and the communication from the first terminal to the second terminal is completed.
As shown in fig. 5, fig. 5 schematically illustrates a schematic diagram of a vehicle equipped with V2X and a vehicle equipped with V2X according to some embodiments of the present invention, in step S510, a User ID, i.e., User1, corresponding to a User1 vehicle is matched at a cloud service layer, and after the request verification of the User1 is passed, a data packet sent by the User1 vehicle to the User2 vehicle through an LTE (Long Term Evolution) network is received, and it is detected whether the data packet is in a V2X standard format; in step S520, it is determined that the data packet is in the V2X standard format, the User ID corresponding to the User2 vehicle end, that is, the User2, is matched, and a test request is sent according to the User2 to detect whether the User2 vehicle end can receive the data packet in the V2X standard format; in step S530, it is determined that the User2 car can receive the data packet in the V2X standard format, and the data packet in the V2X standard format is transmitted to the User2 car, so as to complete the communication from the User1 car to the User2 car.
In some exemplary embodiments of the present invention, when the determination result is the fourth mode, that is, when it is determined that the first terminal sends a data packet that is not in the V2X standard format and the second terminal cannot receive the data packet in the V2X standard format, the second terminal may process the data packet in the predetermined data format by itself without the assistance of the third party platform, so that the data packet is transmitted to the second terminal, and the communication from the first terminal to the second terminal is completed.
As shown in fig. 6, fig. 6 schematically illustrates a communication between a vehicle not equipped with V2X and a vehicle not equipped with V2X, in step S610, a User ID, i.e., User1, corresponding to a User1 vehicle is matched at a cloud service layer, and after the request verification of the User1 is passed, a data packet sent from the User1 vehicle to the User2 vehicle is received, and it is detected whether the data packet is in a V2X standard format; in step S620, it is determined that the data packet is not in the V2X standard format, the User ID corresponding to the User2 vehicle end, that is, the User2, is matched, and a test request is sent according to the User2 to detect whether the User2 vehicle end can receive the data packet in the V2X standard format; in step S630, it is determined that the User2 car end cannot receive the data packet in the V2X standard format, the data packet in the predetermined data format is transmitted to the User2 car end, the playing data is displayed through an HMI (Human Machine Interface), the communication from the User1 car end to the User2 car end is completed, and the communication from the User1 car end to the User2 car end is completed.
Further, the service layer at the third platform end may add data elements of the first terminal related to the user of the second terminal to the parsed data when the parsed data in the data packet is packaged according to the predetermined data format/V2X standard format. For example, when the User1 car end is close to the User2 car end, the User1 car end sends a collision warning to the User2 car end, and the application layer in the cloud retrieves the User information of the two cars in the big data platform and adds the elements of the associated social attributes to become sentences containing social elements, such as "i is a sister and you are too close to me will be tensed".
