Abstract
When starting subscribe for acquiring presence information, there is no need of acquiring an identifier of the presentity or an identifier of the group, which have been conventionally indispensable. There is provided a state information management system including a management server for managing state information on a plurality of terminals. Instead of specifying a presentity, a condition of the presentity, such as a value of presence, is specified for subscribing. For example, when subscribe is established by specifying the identical current position as a condition, subscribe for the user matched with the condition is automatically started and the presence can be acquired. When the presence of a partner or user himself/herself is changed to a different value, the presentity is automatically changed.
