Abstract
To realize state estimation that corresponds with an actual situation by dynamically changing an abstract state calculation method. Upon receiving an abstract state monitoring request, an abstract state generation section 10 extracts a constituent element of an abstract state from the request, selects a rule for calculating an abstract state from the presence of the element, and generates a presence servicing client 20 that has a watcher for observing the element via a presence servicing section 40 and a presentity for issuing the presence of the abstract state to the presence service. Further, the rule for calculating an abstract state is changed in accordance with presence.
