Method for downloading content into a first terminal from a server, via a first wide area telecommunications network, comprising a step of setting up a first communication from the first terminal, according to a predetermined communication protocol, in the course of which the first terminal transmits a download request for a content to said server, via said first wide area telecommunications network, said method being characterized in that it comprises, on the first terminal, the following steps: - intercepting said content download request, - discovering at least one second terminal connected to the first terminal via a local area telecommunications network, the second terminal being moreover connected to a second wide area telecommunications network, in the course of which the first terminal: • sends to the second terminal a message that contains identification information for the server, • receives from the second terminal a message (OF_BP2) offering to share the second wide area telecommunications network, for the purpose of said content download, the message offering to share containing a port identifier associated with the second terminal, - determining at least one first data segment of the content to be downloaded on the basis of the offer to share contained in the received message, - setting up a second communication from the first terminal, according to said predetermined communication protocol, in the course of which the first terminal, via said local area telecommunications network: • transmits to the port associated with the second terminal a download request for the determined first content segment, • receives from the second terminal the first content segment that has been obtained previously by the second terminal following a connection by the latter to said server, via the second wide area telecommunications network, by means of the identification information for the server that was sent by the first terminal in the discovery step. - intercepting said content download request, - discovering at least one second terminal connected to the first terminal via a local area telecommunications network, the second terminal being moreover connected to a second wide area telecommunications network, in the course of which the first terminal: • sends to the second terminal a message that contains identification information for the server, • receives from the second terminal a message (OF_BP2) offering to share the second wide area telecommunications network, for the purpose of said content download, the message offering to share containing a port identifier associated with the second terminal, • sends to the second terminal a message that contains identification information for the server, • receives from the second terminal a message (OF_BP2) offering to share the second wide area telecommunications network, for the purpose of said content download, the message offering to share containing a port identifier associated with the second terminal, - determining at least one first data segment of the content to be downloaded on the basis of the offer to share contained in the received message, - setting up a second communication from the first terminal, according to said predetermined communication protocol, in the course of which the first terminal, via said local area telecommunications network: • transmits to the port associated with the second terminal a download request for the determined first content segment, • receives from the second terminal the first content segment that has been obtained previously by the second terminal following a connection by the latter to said server, via the second wide area telecommunications network, by means of the identification information for the server that was sent by the first terminal in the discovery step. • transmits to the port associated with the second terminal a download request for the determined first content segment, • receives from the second terminal the first content segment that has been obtained previously by the second terminal following a connection by the latter to said server, via the second wide area telecommunications network, by means of the identification information for the server that was sent by the first terminal in the discovery step.
