Abstract
A system and methods are shown for providing presence state services in an Internet Protocol network. One exemplary system includes a central presence element configured to track and provide user presence state information, and a local presence element in communication with the central presence element and further in communication with a signaling entity. According to one embodiment, the local presence element is configured to create and manage local presence state authorization data generated based on user presence state information being received from the central presence element. Further, the local presence element is configured to authorize a user service request using the local presence authorization data before providing access to a service requested by the user in the user service request.
