V2R COMMUNICATION TEST SYSTEM AND TEST METHOD BASED ON 5G TECHNOLOGY

摘要

The present invention discloses a vehicle to roadside (V2R) communication test system based on 5G technology. The network element function is realized by means of virtualization and softwarization, which can greatly increase network transmission rate, guarantee dense concurrence of network message by means of a network terminal under the environment of Internet of Vehicles (IOV), and meet the requirements of ultralow time delay of IOV application. The system cloud server adopts virtualization technology to reduce the number of servers. In consideration of safety, a plurality of network slices are divided to provide dedicated logic network of safe isolation and high automatic control, thereby greatly increasing network security as well as guaranteeing information security of IOV applications and privacy of user data. An edge cloud server sinks part of business to the network edge, thereby greatly increasing the business processing speed of IOV based on roadside devices as well as providing lower transmission time delay. A test platform can be used for verifying the actual effectiveness of 5G technology applied in IOV applications, and providing support to 5G-based IOV device layout and network design in real scenes.
