摘要:
A data delivery device includes a receiving section, a retrieval section and a transmitting section. The receiving section receives a download request from a requesting mobile device which requests data to be downloaded. The retrieval section retrieves existence of surrounding mobile devices existing within a predetermined region from the requesting mobile device with using management information including positions of the surrounding mobile devices, when the receiving section receives the download request. The transmitting section transmits setting information to the requesting mobile device in order to enable the requesting mobile device to receive the data from an arbitrary one of the surrounding mobile devices.

A download system capable of appropriately spreading loads on a server and on a transmission path, and further enhancing convenience in download of data. A reservation candidate acquirer of a communication terminal acquires from a software managing server reservation candidate information containing time information about time zones as candidates to which a reservation for download of an update file can be allocated. At the communication terminal a user selects a reserved time zone from the time zones corresponding to the time information included in the reservation candidate information, and the software managing server registers the reservation in the reserved time zone. Thereby, the reserved time zone can be selected from the candidate time zones transmitted by the software managing server and the candidate time zones are determined based on a reservation table set so as to spread loads on the software managing server and on the transmission path.

A data delivery device includes a storage unit for storing data, a receiving unit for receiving, from a client terminal, a request to download data to be stored into the storage unit and information indicative of a present position of the client terminal, through a network. The data delivery device also includes a judging unit for judging, in response to the download request received by the receiving unit, whether data to be stored into the storage unit is to be transmitted to the client terminal or to another predetermined terminal on the basis of a present position of the client terminal, and a delivery unit for delivering the data to a terminal destination based on the result of the judgment.

摘要:
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.
