Abstract: A method, implementable on a mobile device, includes activating at least two of the output devices of the mobile device in response to a call-related activity, where the output devices include an audio/video device and at least one non-audio/video device, and stopping the activating when the call-related activity ends.

Abstract: A method includes detecting a roaming status of a mobile communication device communicating with a server as a function of the corresponding IP address of the mobile communications device as presented to the server.

Abstract: A system includes a unit to receive triggering events from a network operator and a unit to provide media content to a terminal for playing by a media player on the terminal in response to the triggering events. One embodiment is implemented with an IMS (IP multimedia subsystem). In this embodiment, the unit to receive is an application server of an IMS system and the unit to provide has at least one media resource unit of the IMS system and a community server. The community server associates media content with terminals of the IMS system and in response to triggering events and activates the IMS system to provide media content to a relevant terminal in response to a relevant triggering event.
