To provide a system for acquiring store information only by a DSRC communication network without processing any complicate procedure in a parking lot where a DSRC communication system is set.

The parking of a vehicle 101 is detected, and parking information and the mail address of a portable terminal 112 carried by the user of the vehicle are transmitted from an on-vehicle device 109 to a control center 104 at a parking lot side. The control center side receives the transmission signal, and starts parking charging processing, and distributes advertisement information such as store advertisements near the parking lot, the list of the URL of each store and the simple map of each store to the portable terminal designated by the mail address.
