Data processing method and apparatus, vehicle-end device, cloud server, and electronic device

A device comprising:

• at least one memory configured to store instructions;
• and
• at least one processor coupled to the memory and configured to execute the instructions to cause the device to:
• send, to a cloud server coupled to the device via a communication link, a first message to access a roadside device;
• receive, from the cloud server, a second message that is based on the first message and on a prestored high-definition map, wherein the second message comprises information about accessing the roadside device by the device;
• and
• access the roadside device based on the second message.

A cloud server comprising:

• at least one memory configured to store instructions;
• and
• at least one processor coupled to the memory and configured to execute the instructions to cause the apparatus to:
• receive, from a device coupled to the cloud server via a communication link, a first message requesting to access a roadside device and to obtain signal transmit power-related information of a static roadside equipment;
• generate, based on the first message and a prestored high-definition map, a second message comprising information regarding accessing the roadside device and the signal transmit power-related information;
• and
• send the second message to the device.

A cloud server comprising:

• at least one memory configured to store instructions;
• and
• at least one processor coupled to the memory and configured to execute the instructions to cause the cloud server to:
• receive, from a device coupled to the cloud server via a communication link, a first message requesting to access a roadside device;
• generate, based on the first message and a prestored high-definition map, a second message comprising information regarding accessing the roadside device by the device, wherein the second message is configured to enable the device to access the roadside device;
• and
• send the second message to the device.
