Abstract

A method of providing a continuous downloading service of large size content through a wireless network consisting of a mobile terminal and a content server is disclosed. In one aspect, the method comprises receiving a request; receiving a package list from the mobile terminal; comparing information of an individual file in the received package list and information of an individual file in the content server; and transmitting a required file list indicating at least one individual file having different information in the received package list and the stored package list to the mobile terminal, wherein the required file list comprises a content unified version. A download program installed in the mobile terminal receives the required file list and determines the continuous download.
