Abstract: The present invention provides distributed communication services based on a presence technology platform. Presence messaging and communication techniques allow a variety of communication agents to cooperate with one another to provide distributed services. Essentially, the messaging between the agents is used to facilitate media sessions and update participating devices of state changes bearing on providing the services. In one embodiment, each of the participating devices is associated with a logic entity, referred to as a presentity, which subscribes to notification services for the other participating devices. When a state change occurs on any one of the participating devices, the corresponding presentity notifies the other devices of the state change. As such, each participating device knows the status of the other participating devices via the presentities and can systematically determine when and how to provide services based on its current state and the current state of the other participating devices.

Abstract: The present invention provides a presence system capable of efficiently controlling the delivery of presence information for select individuals to a subscriber. Even if the subscriber has numerous individuals identified in a contacts list, only presence information for those individuals in an active list is provided to the subscriber. The active list can be relatively static or configured to change based on time and date, monitored events, availability of the subscriber, or other predefined criteria. The user can readily add or remove individuals from the active list in addition to selecting an inactive individual to monitor on an instantaneous basis, for a select period of time, until a successful communication occurs between the subscriber and selected individual, or until monitoring is no longer desired. The user can also issue one-time queries of typical or more detailed presence information about specific individuals.
