Abstract

A data deliver device for delivering data to a mobile terminal includes a position information storage unit, a traffic information storage unit, and a decision unit. The position information storage unit stores intended position information that concerns an intended position of the mobile terminal during every period of time. The traffic information storage unit stores predictive traffic information concerning predicted traffic at each position during every period of time. The decision unit extracts the predicted traffic at the intended position of the mobile terminal during every period of time, on the basis of the intended position information stored in the position information storage unit and the predictive traffic information stored in the traffic information storage unit. In addition, the decision unit decides the delivery time of data, on the basis of the extracted traffic predicted at the intended position of the mobile terminal during every period of time.

Claims

1. A data deliver device for delivering data to a mobile terminal, comprising:

a position information storage means for storing intended position information that concerns an intended position of the mobile terminal during every period of time;

a traffic information storage means for storing predictive traffic information concerning predicted traffic at each position during every period of time; and

a decision means for extracting the predicted traffic at the intended position of the mobile terminal during every period of time, on the basis of the intended position information stored in the position information storage means and the predictive traffic information stored in the traffic information storage means, and for deciding the delivery time of data, on the basis of the extracted traffic predicted at the intended position of the mobile terminal during every period of time.

2. The data deliver device according to claim 1, wherein the decision means decides the delivery time of the data again, when judging that allowable transfer capacity of network of a wireless base station with which the mobile terminal communicates at the predicted delivery time of the data is less than or equal to a predetermined threshold.

3. A method for changing a delivery time of data of a data delivery device that delivers the data to a mobile terminal at a predetermined time, the method comprising the steps of:

extracting predicted traffic at an intended position of the mobile terminal during every period of time, on the basis of intended position information that concerns an intended position of the mobile terminal during every period of time and predictive traffic information concerning predicted traffic at each position during every period of time; and

deciding the delivery time of data, on the basis of the extracted traffic predicted at the intended position of the mobile terminal during every period of time.
