The message conversion function unit (60) includes an object-to-be-converted acquisition unit (61) and a message conversion unit (62). The object-to-be-converted acquisition unit (61) acquires, as a message to be converted, a message which, due to being present in a basic area which is the inside of a mobile body or an extension area equated with the basic area on the outside of the basic area, is transmitted/received within the basic area or between the basic area and the extension area, the acquisition being made in an interval from when the message is generated on a transmission side to when the message is presented to a user on a reception side. The message conversion unit (62) converts the message to be converted in accordance with a predetermined message conversion process to acquire a converted message.
