A consumer node 20 transmits the data requesting the mediate information of the service organizer node 30 to the mediator node 12. The mediator node 12 transmits the mediate information to the consumer node 20 in response to a request from the consumer node 20. The consumer node 20 transmits the data indicating the service to be provided to the service organizer node 30. The service organizer node 30 transmits the program module etc. for realizing the service to the consumer node 20 to provide the requested service.
