The source device includes a Public Land Mobile Network interface and the reference information is transmitted via the Public Land Mobile Network interface. A second step 2) includes transmitting a target information, including information related to a selected target device, to the network instance, the target information being transmitted via the Public Land Mobile Network interface. A third step 3) includes transmitting a usable information from the network instance to the target device, the usable information being related to the reference information and including a media content that is used by the target device at a predetermined time.
