  • LTE-V based internet of vehicles communication test system and test method thereof
    Patent number: 11133879
    Abstract: Disclosed is an LTE-V based Internet of Vehicles communication test system and test method. The test system includes an ENodeB base station, a roadside test unit, user test terminal, LTE-V core network and local server group. Mobile communication technology is applied to the field of Internet of Vehicles communication, and two technical schemes are used, i.e., wide-area centralized cellular communication and short-range distributed direct communication corresponding to the network architectures based on access network-user terminal and ProSe direct communication interface, respectively. Not only the communication transmission support with large broadband in wide coverage can be supported, but also to achieve low latency and highly reliable communication services between vehicle and vehicle, vehicle and base station, base station and base station, to meet the needs of road safety and traffic efficiency applications.
