A method for controlling sharing of at least one electronic content between a first user equipment (UE1) and at least a second user equipment (UE2), a first communication session (CS1) being established between the first user equipment and a server (S) storing electronic contents enabling transmission of at least one electronic content to the first user equipment, the method comprising the following steps executed by the server : Receiving (E2), from the first user equipment, a request (R3) for sharing the transmitted electronic content, transmitting (E8, MSG2, E6', MSG1') to the second user equipment a sharing parameter (SP) generated from at least an identifier of the first user equipment and an identifier of the transmitted electronic content, establishing a second communication session (CS2) with the second user equipment associated with the sharing parameter, following a request comprising the sharing parameter emitted by the second user equipment, determining (E11, E13), based on the sharing parameter, that the user equipment requesting a sharing of an electronic content is the first user equipment and the electronic content to be shared is the transmitted electronic content, and if the transmitted electronic content is being played on the first user equipment (E12, E9'), transmitting said transmitted electronic content to the second user equipment in order for said transmitted electronic content to be played simultaneously on the second user equipment, characterized in that : the request (R3) for sharing the transmitted electronic content contains an authorization to play synchronously the selected electronic content on both first and second user equipment, wherein the server further triggers that the transmitted electronic content is to be played synchronously (E12', E14) or not (E11', E13) on the first user equipment and on the second user equipment, depending on said synchronization authorization information. Receiving (E2), from the first user equipment, a request (R3) for sharing the transmitted electronic content, transmitting (E8, MSG2, E6', MSG1') to the second user equipment a sharing parameter (SP) generated from at least an identifier of the first user equipment and an identifier of the transmitted electronic content, establishing a second communication session (CS2) with the second user equipment associated with the sharing parameter, following a request comprising the sharing parameter emitted by the second user equipment, determining (E11, E13), based on the sharing parameter, that the user equipment requesting a sharing of an electronic content is the first user equipment and the electronic content to be shared is the transmitted electronic content, and if the transmitted electronic content is being played on the first user equipment (E12, E9'), transmitting said transmitted electronic content to the second user equipment in order for said transmitted electronic content to be played simultaneously on the second user equipment, the request (R3) for sharing the transmitted electronic content contains an authorization to play synchronously the selected electronic content on both first and second user equipment, wherein the server further triggers that the transmitted electronic content is to be played synchronously (E12', E14) or not (E11', E13) on the first user equipment and on the second user equipment, depending on said synchronization authorization information. <EOS>
