Abstract

As an embodiment, a delivery data management section stores data to be delivered and an access status management section stores information indicating the frequency of use of a client terminal and a used time zone. A delivery time calculation section picks out a time zone of which frequency of use of a portable unit is smaller based on the stored information indicating the frequency of use, and determines the picked out time zone as the delivery time of the data, and a delivery section delivers the data stored in the delivery data management section at the determined delivery time.

Claims

1. A data delivery device, comprising:

storage means that stores data;

management means that stores information indicating frequency of use of a client terminal and a used time zone;

determination means that determines a time zone picked out based on the frequency of use of the client terminal stored in the management means, as a delivery time of the data stored in the storage means; and

delivery means that delivers the data stored in the storage means at the delivery time determined by the determination means.

2. The data delivery device according to claim 1,

wherein the storage means further stores a delivery time limit for delivering the data, and

the determination means determines a time zone picked out based on the frequency of use of the client terminal within the delivery time limit stored in the storage means as the delivery time.

3. An alteration method of a data delivery time, comprising the steps of:

receiving information indicating frequency of use of a client terminal and information of a used time zone;

determining a time zone picked out based on the received frequency of use as a delivery time of the data; and

delivering the data at the determined delivery time.
