Document Type and Number:
Japanese Patent JP3465616
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To allow a user of a mobile communication terminal to recognize a communication cost before actual downloading when the mobile communication terminal downloads data from a information distribution center.
SOLUTION: An information distribution center recognizes a data capacity Pn of requested data, a communication speed V of a communication line, and date time dependent charging condition K on the basis of date time information when downloading is executed (S550, S560, S580) in response to a download request from a mobile communication terminal, substitutes them to a communication cost calculation equation [Ln=Pn/V×K] to calculate the communication cost Ln. Moreover, the communication speed and the date time dependent charging condition K depend on a contract condition of each user with a telephone company registered as user information. Then the calculation result is informed to the mobile communication terminal (S610). The mobile communication terminal receives the notice of the calculation result (S340), and displays the communication cost for data making the download request.
