PROBLEM TO BE SOLVED: To solve the problem in conventional subscription for acquiring presence information that acquisition of an ID of a subscription object by any method and designation thereof are required for starting the subscription.;SOLUTION: In this method, subscription is performed by designating not the subscription object but a condition of subscription object (a value of presence, etc.). When subscription is performed, for example, on condition of the same current position, subscription to a user matched to the condition is automatically started, and the presence can be acquired, while the subscription object is automatically changed if the presence of a partner or the user himself/herself is changed to a different value. According to this, the subscription can be started without needing prior acquisition of a user ID, a group ID or the like of the subscription object.;COPYRIGHT: (C)2007,JPO&INPIT
