The invention relates to a method for downloading a digital file by a user, from a content server to a mobile terminal via a mobile telecommunication network, said method consisting of the following steps: the mobile terminal is connected to the server via the network; the file is downloaded from the server to the terminal in such a way that it is encrypted as a background task; and the file is presented to the user once the downloading has been completed. The inventive method is characterised in that: it comprises another step, before the connection step, for checking that the current time belongs to a pre-determined time slot; mechanisms for controlling the interruption of the downloading are set up, said mechanisms enabling partial versions of the file to be saved on the terminal and to then download only the missing part in the event of an interruption; the bandwidth is monitored in real time and triggers the temporary suspension of the downloading as required; and the acceptance of the content by the user once the file has been presented after being downloaded triggers the emission of an acceptance message from the terminal to the server, and the return transmission, from the server to the terminal, of a decryption message enabling the terminal to decrypt and read the downloaded file. The invention also relates to a system for carrying out the inventive method.
