Location-based presence automation

The present invention provides for an improved presence system, which can automatically and unobtrusively factor in the location of a person being monitored when creating presence information for dissemination to subscribers. Presence tags can be distributed at different locations, which may bear on the relative availability of the monitored person for communications. A mobile terminal associated with the monitored person is configured to automatically obtain tag information from the presence tags and deliver location-based state information to the presence server without human interaction. The presence server will process the location-based state information and any other applicable state information to create presence information for the person being monitored, and then deliver the presence information to subscribers.
