RESERVATION SYSTEM, RESERVATION SERVER, RESERVATION PROGRAM FOR RESERVATION SERVER, COMMUNICATION TERMINAL DEVICE, AND RESERVATION PROGRAM FOR COMMUNICATION TERMINAL DEVICE

摘要

In order to make a reservation of services required to make a reservation dynamically acceptable, so that convenience and the degree of freedom for users are improved, a reservation server (10) accepts a preliminary reservation of a service required to make a reservation that a user desires in a prescribed time width. When the user who moves to a starting point of the service required to make a reservation passes through a passage point and a detecting device detects that a communication terminal device (20) held by the user also passes through the passage point, the reservation server (10) is notified of passage information that the communication terminal device (20) passes through the passage point. When the reservation server (10) receives the passage information, the service required for a reservation for which the preliminary reservation has been made accepts a formal reservation in a range of a prescribed time width.
