PROBLEM TO BE SOLVED: To provide a mobile communication system capable of highly reliable communication.SOLUTION: A mobile communication system 100 includes: an on-vehicle terminal 300 which includes an antenna to be used in a vehicle 4 for a selective resource to communicate using a selected resource, to perform radio communication using the antenna for the selective resource; and a base station 200 to be communicated with the on-vehicle terminal 300. There are provided: a propagation path characteristic acquisition unit which acquires propagation path characteristic information, which is information related to a propagation path characteristic between a reference antenna, having a common antenna characteristic at least including an antenna type to the antenna for the selective resource, and the base station 200, in an associative manner with a future communication position; and a resource selection unit which, based on the propagation path characteristic information acquired by the propagation path characteristic acquisition unit, selects a resource to be used for communication between the on-vehicle terminal 300 and the base station 200 at a communication position, before the antenna for the selective resource of the on-vehicle terminal 300 is positioned at the communication position.SELECTED DRAWING: Figure 1
