A first UE (User Equipment) initiates a device discovery procedure by registering (41) to an IMS-based service, e.g. an IPTV service, using a subscribe signalling procedure with the Application server, and the Application server responds by notifying (42) the UE of the other registered UEs under the same IMS subscription. Thereby, the first UE can enable a selected (43) UE of the other registered UEs to initiate a specific media session, by sending (44) a session push comprising at least a content identifier and the identity of a selected UE to the Application Server, to be forwarded to the selected target UE. |
