A wireless communication system according to one mode of the present invention includes: an information providing terminal being a communication terminal belonging to a first node below, the information providing terminal configured to transmit, to another station, first provision information that includes source data usable for driving support control; a base station belonging to a second node below and configured to transmit, to another station, second provision information based on the source data; a server belonging to a third node below and configured to transmit, to another station, third provision information based on the source data; an information acquiring terminal being a communication terminal belonging to the first node below, the information acquiring terminal being mounted to a target vehicle to which the first to third provision information is to be provided; and a determination unit configured to determine whether or not adoption of the first to third provision information is allowed, on the basis of a position of the target vehicle and a position associated with the source data. First node: a communication node configured to perform terminal-to-terminal communication in a first network slice. Second node: a communication node configured to communicate with the first node in a second network slice. Third node: a communication node configured to communicate with the first node via the second node in a third network slice.
