Title:
MAP DATA TRANSMISSION METHOD AND SYSTEM, EDGE SERVER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/193511
Kind Code:
A1
Abstract:
Embodiments of the present application provide a map data transmission method and system, an edge server, and a storage medium. A vehicle-mounted device transmits a map data distribution request to a roadside communication unit by means of a vehicle-mounted communication unit; after receiving the request, the roadside communication unit obtains the signal intensity of a communication channel with the vehicle-mounted communication unit, and transmits the signal intensity to an edge server; the edge server sets the packet size and the data packet transmission frequency according to the signal intensity, divides map data into a plurality of data packets according to the packet size, and transmits the data packets to a vehicle-mounted subsystem according to the data packet transmission frequency. Because the edge server sets the packet size and the data packet transmission frequency on the basis of the signal intensity, the effect of the communication quality of a communication channel on map data transmission is reduced, and the data packet transmission efficiency is ensured as much as possible. In this way, a vehicle-mounted device can obtain map data on the basis of received data packets, so that the efficiency of acquiring map data by a vehicle is improved.
