PROBLEM TO BE SOLVED: To flexibly realize link between movable objects on a network. SOLUTION: An embodiment 602 being an object set in a site B communication connected with an entity 601 being an object set in a site A disconnects connection with the entity 601 in the site A, and moves to a site C. The embodiment 602 designates an MUG identifier 1006 corresponding to it, and updates network address information 1007 in an entry including the MUG identifier 1006 in a data base 1003 held by a repository 1001 to that indicating the site C. Then, the embodiment 602 triggers the entity 601 in the site A, and the embodiment 602 in the site C and the entity 601 in the site A collates the repository 1001 as necessary based on the trigger so that mutual communication connection can be re-established. |
