In this paper, we re-define a community be appropriate for

intention or interest of users who are main body in ubiquitous
computing environment. Its creation, maintenance and
extinction are determined by the subject user's behavior.
Community contains users or user groups located in the
environment, devices which executed to achieve user's
intention, services, and contents as members. It is a particular
feature of user centric community. In other words, user centric
community is a virtual collaborative collection consisting of
users and smart objects to achieve the user's interest. In our Figure 2 u-Community Manager
point of view, users with mobile device are special case of
