摘要

In an information distribution service system comprising a plurality of mobile information terminals (6#i), a computer system (2) and a plurality of information-provider terminals (4#i), the computer system (2) is provided with a user-information database (26) for registration information categories provided for the mobile information terminals' (6#i) users each serving as a recipient of an information distribution service rendered by the information distribution service system, an information-provider database (26) for registering locations of the information-provider terminals (4#i) and information to be distributed by the information-provider terminals (4#i) as notifications, and a location management unit (22) provided for the purpose of inferring changes in location of each mobile information terminal in a time series by using an inference formula provided in advance for predicting the particular mobile information terminal's (6#i) moving direction and location on the basis of information on locations of the particular mobile information terminal (6#i).
