Abstract

Embodiments of the present invention are directed to facilitating apparatus interaction. In at least one example embodiment of the present invention, apparatuses may comprise both triggered communication activities and automated communication activities. Triggered communication activities may correspond to, for example, user and/or application instigated actions in a wireless apparatus. Automated activities may occur without any requirement for user intervention, and further, without any notification to the user that an action has occurred.
