The invention discloses an Internet of Vehicles switching method and device based on ultra-dense networking, and the method comprises the steps: constructing an Internet of Vehicles access matrix according to a vehicle set at a current moment, an accessible network set and the connection state of a vehicle and an access network, and obtaining an Internet of Vehicles access matrix according to a first impact parameter and the accessible network set; respectively calculating an access preference degree utility function of the target vehicle to each accessible network; according to the second influence parameter and the accessible network set, respectively calculating a vehicle state evaluation utility function of each accessible network for the target vehicle; and determining the target access network through the user according to the own needs and the network state information of the network side. By implementing the invention, the problems of simpler switching algorithm, longer switching time delay and inapplicability to high-speed scenes with variable position topologies in the Internet of Vehicles in the existing network switching technology are solved, the optimal network is efficiently determined for the vehicle, the network experience of a user in a mobile environment is improved, and the reasonable utilization of network resources is realized.
Description
technical field [0001] The present invention relates to the technical field of Internet of Vehicles communication, in particular to a method and device for switching Internet of Vehicles based on ultra-dense networking. Background technique [0002] In heterogeneous wireless networks, Vertical Handover (VH) is a major way to provide seamless handover between different network environments. Since the coverage of the network is certain, there is no single network that can provide ubiquitous and continuous high-quality network services. Currently, mobile terminals often use multi-mode access technologies to maintain network connectivity and user satisfaction. In the Internet of Vehicles environment, vehicles as access terminals often have the characteristics of fast movement, and there are often vehicles gathering in an area, that is, there may be multiple vehicles that need to select the access network for the next period at the same time. These characteristics will have an ...
