Network selection method and device and storage medium

The invention provides a network selection method and device and a storage medium, relates to the technical field of communication, and is used for solving the technical problem that a proper communication network cannot be accurately selected by a general technology. The network selection method comprises the following steps: acquiring a candidate network set in a vehicle driving direction; determining a utility value of each candidate network in the candidate network set according to the plurality of network performance parameters; one network performance parameter is used for representing the performance of the candidate network under one network performance index; the utility value is used for representing the network quality of the candidate network; determining a selection proportion of each candidate network; the selection proportion is used for representing the probability that the candidate network is selected as the target network; and determining a target network to which the vehicle is to access a
