A supercomputer, with traffic-modeling software and 5G/6G connectivity, can assist an autonomous vehicle in avoiding, or at least minimizing the expected harm of, an imminent collision. Upon detecting the imminent collision, the autonomous vehicle can transmit a message to an access point, requesting an uncontested direct communication link to the supercomputer, and then transfer sensor data and other traffic data to the supercomputer through the access point. The supercomputer can calculate a multitude of sequences of braking, steering, and accelerating actions of the autonomous vehicle, and can select the sequence that enables the autonomous vehicle to avoid the collision if possible. If all sequences cannot avoid the collision, the supercomputer can select the sequence that results in the least harm (fatalities, injuries, and property damage) in the unavoidable collision. The supercomputer relays the selected best sequence of actions through the access point to the autonomous vehicle, thereby mitigating the collision.

Provided by the present application are a data transmission method and device, which are used to solve the problem of being unable to accurately transmit an RRC message which is too large. The method comprises: when determining that the length of an original RRC message exceeds a preset threshold, compressing the original RRC message; packaging the compressed RRC message into a PDCP PDU; and sending the packaged PDCP PDU to a receiving end.

In a data transmission method, a transmit end may obtain a first application message generated by a target application running on the transmit end. The transmit end encapsulates the first application message to obtain a first data frame, where the first data frame includes a first frame type identifier, and the first frame type identifier indicates that an application message included in the first data frame is a complete application message. The transmit end transmits the first data frame to a receive end based on an established QUIC connection to the receive end. After receiving the first data frame, the receive end may determine, based on the first frame type identifier in the first data frame, that the application message included in the first data frame is a complete application message.

An automotive network switch includes multiple ports, a switch core and one or more processors. The ports are configured to receive packets from electronic subsystems of a vehicle over a computer network deployed in the vehicle, and to transmit the packets to other electronic subsystems of the vehicle over the computer network. The switch core is configured to receive the packets from one or more of the ports, to forward the packets to at least one of the ports, and to transmit the packets over network links of the computer network. The processors are configured to obtain at least some of the packets processed by the switch, to analyze the obtained packets to identify an anomaly in one or more of the electronic subsystems of the vehicle, and to send a notification of the anomaly over the computer network to a central processor that is external to the switch.
