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.
