In the embodiment of the present application, the cloud server is also called the cloud. The terminal 102 is provided with an on-board electrical component T-BOX, which includes an intelligent identification component.

[0051] In an exemplary embodiment, Figure 2 As shown, a data communication method is provided, which is described by taking the method applied to the terminal 102 in FIG. 1 as an example, and includes the following steps 202 to 206. Among them:

[0052] Step 202, receiving a data packet of autonomous driving data sent by a target application, wherein the target application is any upper layer application in the T-BOX;

[0053] Optionally, the autonomous driving data may be vehicle status data and vehicle form data.

[0054] Exemplarily, data packets of autonomous driving vehicle status data and vehicle driving data sent by a target application are received.

[0055] Step 204, identifying the size of the data packet and querying the required network performance corresponding to the target application;

[0056] The required network performance refers to the network performance required for data transmission, which are low performance requirements and high performance requirements.

[0057] Exemplarily, the storage space size of the data packet and the network performance required by the target application for data transmission are identified.

[0058] Step 206: Based on the size of the data packet and the required network performance, determine a target transmission channel for transmitting the data packet from among multiple transmission channels between the T-BOX and the cloud, encapsulate the data packet into a format supported by the target transmission channel, and transmit the encapsulated data packet to the cloud through the target transmission channel.

[0059] Exemplarily, based on the size of the data packet and the network performance required for data transmission by the target application, a target transmission channel for transmitting the data packet is determined among multiple transmission channels between the T-BOX and the cloud, the data packet is encapsulated into a format supported by the target transmission channel, and the encapsulated data packet is transmitted to the cloud through the target transmission channel.

[0060] The above-mentioned data communication method, apparatus, computer equipment, computer-readable storage medium and computer program product first receive a data packet of autonomous driving data sent by a target application, wherein the target application is any upper-layer application in the T-BOX; then identify the size of the data packet and query the required network performance corresponding to the target application; based on the size of the data packet and the required network performance, determine the target transmission channel for transmitting the data packet in multiple transmission channels between the T-BOX and the cloud, and finally encapsulate the data packet into a format supported by the target transmission channel, and transmit the encapsulated data packet to the cloud through the target transmission channel. By encapsulating the data packet into a format supported by the target transmission channel, the underlying wireless communication protocol can be shielded from the upper-layer application, and the upper-layer application can be shielded from the wireless communication protocol, so that the connection and collaboration between wireless devices are smoother.

[0061] In an exemplary embodiment, the multiple transmission channels between the T-BOX and the cloud include a direct communication PC5 channel and a cellular network communication 5G Uu channel, and the 5G Uu channel includes multiple communication interfaces; the determining, based on the size of the data packet and the required network performance, a target transmission channel for transmitting the data packet from the multiple transmission channels between the T-BOX and the cloud includes:

[0062] If the size of the data packet is smaller than a preset value and the required network performance is smaller than a preset level, the transmission status of the PC5 channel is identified; and based on the transmission status of the PC5 channel, a target transmission channel for transmitting the data packet is determined.

[0063] Among them, the PC5 channel is the communication interface between terminals, that is, the short-distance direct communication interface between vehicles, people, and road infrastructure; its characteristics are: low-latency, high-capacity, and highly reliable communication through direct connection, broadcasting, and network scheduling.

[0064] Among them, the 5G Uu channel is the communication interface between the terminal and the base station; its characteristics are: achieving reliable communication over long distances and a larger range.

[0065] Optionally, the preset value may be 10M.

[0066] The preset level is a pre-set network performance indicator, which is used to determine whether the required network performance is a high-level performance requirement or a low-level performance requirement. Optionally, the preset level can be: RSRP is -44dBm, SINR is -20, network delay is 30ms, and packet loss rate is 0.5%. If any one of the RSRP, SINR, network delay, and packet loss rate of the required network performance is higher than the preset level, it is a high-performance requirement, otherwise it is a low-performance requirement.

[0072] The data packet is encapsulated into a format supported by the PC5 channel, and the encapsulated data packet is transmitted to the roadside device, which then transmits the encapsulated data packet to the cloud.

[0073] Exemplarily, if the amount of data transmitted in the PC5 channel is overloaded, the network status information of multiple communication interfaces in the 5G Uu channel is identified, and an idle communication interface is selected from the multiple communication interfaces as the target transmission channel according to the network status information; if the amount of data transmitted in the PC5 channel is not overloaded, the PC5 channel is used as the target transmission channel, and the PC5 channel is used to transmit the data packet to the roadside equipment, and the roadside equipment transmits the data packet to the cloud.

[0075] In an exemplary embodiment, the method further comprises:

[0076] If the data packet is larger than a preset value, or the required network performance is greater than or equal to a preset level, the network status information of multiple communication interfaces in the 5G Uu channel is identified, and the target transmission channel is determined from the multiple communication interfaces based on the network status information.

[0077] Exemplarily, if the data packet is larger than 10M, or any one of the required network performance indicators of RSRP, SINR, network delay and packet loss rate is greater than or equal to a preset level, the network status information of multiple communication interfaces in the 5G Uu channel is identified, and the target transmission channel is determined from the multiple communication interfaces based on the network status information.

[0078] In this embodiment, when the transmitted data packet is large or the network performance requirement is high, the 5G Uu channel is used to transmit data to ensure that important data reaches the cloud in a timely manner.

[0081] Among them, the first threshold is the RSRP requirement in the required network performance, the second threshold is the XINR requirement in the required network performance, the third threshold is the network delay requirement in the required network performance, and the fourth threshold is the packet loss rate requirement in the required network performance.

[0082] A first screening is performed according to the network coverage area in the network status information, and the communication interfaces whose network coverage area covers the area where the autonomous driving vehicle is located are retained to obtain the communication interfaces after the first screening; a second screening is performed according to the network status information of the communication interfaces after the first screening, and the communication interfaces whose RSRP is greater than the RSRP requirement in the required network performance, whose SINR is greater than the XINR requirement in the required network performance, whose network delay is less than the network delay requirement in the required network performance, and whose packet loss rate is less than the packet loss rate requirement in the required network performance are retained to obtain the communication interfaces after the second screening; and a communication interface is randomly selected from the communication interfaces after the second screening as the target transmission channel.
