摘要

PROBLEM TO BE SOLVED: To allow an appropriate amount of data on the destination of a link in a web page obtained by a mobile communication terminal to be prefetched.;SOLUTION: A data prefetch system 1 includes: a terminal travel path estimation unit for estimating the travel path of a mobile communication terminal 10 according to the travel state of the mobile communication terminal 10; an out-of-service information calculation unit 35 for calculating out-of-service information including out-of-service continuous time period that is a time period during which the mobile communication terminal 10 stays within the out-of-service area, according to the travel path; and a prefetch data determination unit 17 for determining the amount of data to be prefetched relating to the data on the destination of a link in a web page, according to the out-of-service information. Then, a data prefetch is executed in the mobile communication terminal 10 according to the determined data amount. For this reason, an appropriate amount of data reflecting a travel state is allowed to be prefetched.;COPYRIGHT: (C)2014,JPO&INPIT
