Abstract: A map data processing method includes obtaining risk event information that includes time information and location information, where the time information indicates a predicted time range of a risk event, and the location information indicates a predicted region range of the risk event. Prediction of a risk event that may occur in a specific geographical region range can be provided. In addition, a lowest-risk path can be further planned based on the risk event information.

Abstract: In a communication method, when MAC addresses in a plurality of VSI messages conflict, in response to only some of the VSI messages, a VSI message receiving end sends an action response message carrying a conflicting MAC address. In this way, a device that can correctly decrypt the action response message can decrypt, for a few times, ciphertext information in received action-request messages using a key of the device.

Abstract: A road side apparatus obtains a first map message. The first map message includes map element information describing a map element, and a time attribute of the map element information. The map element includes at least one of a node-level map element, a road-level map element, or a lane-level map element. The map element information includes at least one of node-level map element information, road-level map element information, or lane-level map element information. The road side apparatus sends the first map message. A terminal obtains the map element information and the time attribute from the first map message.

Abstract: A second device sends a first message to a first device to request the first device to establish a unicast connection to the second device. The first message carries a medium access control (MAC) address, an address identifier, and a security mechanism of the second device. The first device determines, based on the first message, that establishment of the unicast connection between the first device and the second device is abnormal, and sends a second message to the second device. The second message carries the MAC address, the address identifier, and an error identifier of the second device, so that the second device performs corresponding handling based on a reason why establishment of the unicast connection is abnormal that is indicated by the error identifier.

Abstract: Embodiments of the present application provide a broadcast mechanism-based unicast session system, method, and apparatus, a computer-readable storage medium, and a vehicle, to establish a unicast session carried through broadcast between an initiator device and a responder device. An extension identifier of the initiator device or the responder device is added to a unicast request message, a unicast response message, or a unicast acknowledgment message sent in a broadcast manner, to avoid a session error caused by a MAC identifier conflict of the initiator device or the responder device, thereby improving reliability of the unicast session.
