Equipment 1 includes a service provision functional unit 1f, an information processing unit 1e, a correspondence relation collecting functional unit 1c, a correspondence relation storage unit 1b, and a service request functional unit 1d. The information processing unit 1e has one or more objects, and provides control information to the service provision functional unit 1f by executing the object upon receiving a service request including a specific identifier. The correspondence relation collecting unit 1c collects a correspondence relation between the specific identifier of the object and address information of the equipment 1 from the equipment 1. The correspondence relation storage unit 1b stores the correspondence relation between the specific identifier and the address information, which is collected by the correspondence relation collecting unit 1c. While the address information corresponding to the specific identifier used for the service request is stored in the correspondence relation storage unit 1b , the service request functional unit 1d makes the service request on the basis of the address information. As a result, a resource necessary for communication by the use of association between the equipment 1 and the specific identifier can be reduced.
