The present invention enables connection between a wireless sensor node and a service server while reducing load on the wireless sensor node. The wireless sensor node transmits a router solicitation message to a gateway apparatus; the gateway apparatus analyzes the message to extract the discrete information of a device or service, searches for a service server based on such information and acquires the configuration information necessary for execution of a service application of the wireless sensor node; the gateway apparatus multicasts the received router solicitation message into a link; a router within the link receives the router solicitation message, and multicast a router advertisement message which contains the prefix information of an address, etc. into a link; the gateway apparatus sets the acquired configuration information in the router advertisement message and transfers the resultant message to the wireless sensor node; and the wireless sensor node analyzes the message.
