Information processing device, terminal, server, and method for data transfer

摘要

An information processing device includes a first unit which predicts use data used in the future on the basis of action plan information resulting from prediction of an action of a user, and outputs use data identification information; a second unit which predicts a communication state in a situation indicated by the action plan information on the basis of the action plan information and communication environment information regarding a communication environment of the terminal, and outputs information regarding the predicted communication state; and a third unit which calculates a prefetch necessary degree regarding each of the use data on the basis of the use data identification information and the information regarding the predicted communication state.

1. An information processing device comprising:
a use data prediction unit which predicts use data that is assumed to be used by a terminal in the future on a basis of action plan information resulting from prediction of an action of a user of the terminal, and outputs use data identification information for identifying the predicted use data; a communication state prediction unit which predicts a communication state indicating at least time proportion within a range between corresponding time and a location of the communication available in the terminal to a network in a situation indicated by the action plan information on a basis of the action plan information and communication environment information regarding a communication environment of the terminal, and outputs information regarding the predicted communication state; and a prefetch necessary degree calculation unit which calculates a prefetch necessary degree regarding each of the use data on a basis of the use data identification information and the information regarding the predicted communication state.
