Download system, communication terminal, server, and download method

Abstract

The present invention provides a downloading system that can appropriately distribute the load on servers and transmission paths, and further improve the convenience related to data downloading. A reservation candidate obtaining means (14) of a communication terminal (10) obtains reservation candidate information including time information on time slots in which candidates for download reservations for update files can be assigned from a software management server (30). A communication terminal (10) selects a reserved time slot from time slots corresponding to time information included in reservation candidate information, and a software management server (30) registers a reservation for the reserved time slot. In this way, since the reserved time zone can be selected from candidates for the time zone sent from the software management server (30), convenience is improved. In addition, because the candidates for the time zone are obtained based on the schedule set so that the load on the software management server (30) and the load on the transmission path are distributed, the load on the software management server (30) and the load on the transmission path can be appropriately distributed. .

Description

technical field [0001] The invention relates to a downloading system, a communication terminal, a server and a downloading method. Background technique [0002] When a communication terminal downloads data stored in a server, it is necessary to properly control the load on the server and the load on the transmission path. As a technique for coping with this problem, a technique for determining the data transmission time as follows is known, that is, the communication terminal transmits the desired time for downloading data from the server to the server, and the server distributes its load and the load of the transmission path (e.g. , with reference to Japanese Patent Application Laid-Open No. 11-355346). [0003] However, in the above-mentioned prior art, although it is possible to send the desired time for downloading from the user, when the load on the server and the load on the transmission path at this desired time are large, the server automatically distributes the tra...
