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 for storing data;

management means for storing information indicating a frequency of use of a client terminal for each of a plurality of time zones;

determination means for determining one of the plurality of time zones having a smallest frequency of use of the client terminal, based on the information indicating 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 for delivering the data stored in the storage means at the delivery time determined by the determination means,

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

the determination means determines the 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.

2. A method of delivering data, comprising the steps of:

receiving information indicating a frequency of use of a client terminal and for each of a plurality of time zones;

determining one of the plurality of time zones having a smallest frequency of use of the client terminal, based on the received frequency of use within a delivery time limit stored in storage, as a delivery time of the data; and

delivering the data at the determined delivery time.

3. A data delivery device, comprising:

a storage unit configured to store data;

a management unit configured to store information indicating a frequency of use of a client terminal for each of a plurality of time zones;

a determination unit configured to determine one of the plurality of time zones having a smallest frequency of use of the client terminal, based on the information indicating the frequency of use of the client terminal stored in the management unit, as a delivery time of the data stored in the storage unit; and

a delivery unit configured to deliver the data stored in the storage unit at the delivery time determined by the determination unit,

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

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