Abstract
A method for providing presence gateway functionality includes deriving presence information for subscribers in a first set of subscribers based on telecommunications signaling messages. The first set of subscribers includes at least one subscriber who is not a subscribed-to presentity. The method also includes determining whether presence status information for a subscriber in the first set of subscribers has changed. In response to detecting a change in presence status, it is determined whether the subscriber is a subscribed-to presentity. If the subscriber is a subscribed-to presentity, a presence server is notified of the change in status of the subscriber.
