Abstract

The present invention provides a configuration in which a service corresponding to a user can be provided by using an apparatus near the user, even when the user moves from one location to another and apparatuses near the user change. A mobile apparatus carried by the user forms cells, with the mobile apparatus itself being the master, collects information of nearby apparatuses from a space directory (SDR), which stores information of directly-accessible slaves or nearby apparatuses, and generates and updates mobile directory information in a storage unit based on the collected information. Accordingly, the user can obtain the information of nearby information processors unconsciously without performing a special process and, thus, the user can receive services, such as content distribution and communication services, by using the nearby apparatuses based on the obtained information.
