Vehicle-road communication test system and test method on 5G technology

Abstract

The invention discloses a vehicle-road communication test system based on the 5G technology. A network element function is realized by adopting a virtualization and software mode; the network transmission rate can be obviously improved; concurrent network messages of dense network terminals in the Internet of Vehicles environment are ensured. the requirement of complex and huge Internet of Vehicles application on ultra-low time delay is met; the system cloud server adopts a virtualization technology. the number of servers is reduced; in a security aspect, multiple network slices are divided, asecurity isolation and height self-control special logic network is provided; network security is greatly improved, the information security of the Internet of Vehicles application and the data privacy of the user are ensured; the edge cloud server sinks a part of services to a network edge; the Internet of Vehicles application service processing speed based on roadside equipment can be remarkably increased, lower transmission delay is provided, the test platform can be used for verifying the actual effectiveness of the 5G technology applied to the Internet of Vehicles application, and support is provided for 5G-based Internet of Vehicles equipment layout and network design in a real scene.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and relates to a vehicle-road communication test platform and a test method, in particular to a vehicle-road communication test system and a test method based on 5G technology. Background technique [0002] In recent years, due to the continuous growth of the number of vehicles, the problems of traffic safety, travel efficiency, and environmental protection have become increasingly prominent, making research and development in related fields of the Internet of Vehicles attract extensive attention. The core technology of the Internet of Vehicles - V2X wireless communication technology, can realize technologies such as non-line-of-sight perception and vehicle information sharing that are difficult for a single car to achieve in terms of intelligent development. At present, the internationally mature V2X wireless communication technology is a dedicated short-range communication tech...
