Abstract
A communication system includes a client, gateway apparatus, and information source server. The client includes a setting section for setting a parameter and a notification section for notifying the parameter set by the setting section. The gateway apparatus includes an acquisition section for generating an information acquisition request on the basis of the parameter notified by the notification section, an information storage section for temporarily storing information received in response to the acquisition request generated by the acquisition request section, and an information transfer section for transferring the information stored in the information storage section to the client. The information source server includes an information storage section for storing the information acquired by the acquisition request section, and an information transmission section for transmitting the information stored in the information storage section to the gateway apparatus upon reception of the acquisition request.

10. A communication method comprising:
-
the creation request step of causing a client for displaying acquired information to request a gateway apparatus to create an agent for information acquisition;
the area reservation step of causing the gateway apparatus to reserve a predetermined storage area for each agent whose creation is requested in the creation request step;
the parameter setting step of causing the gateway apparatus to set the parameter notified for each agent by the client in the storage area reserved in the area reservation step;
the acquisition request step of causing an agent in the gateway apparatus to generate an acquisition request to a server storing various kinds of information on the basis of the parameter set by the parameter setting means;
the information transmission step of extracting information for which the acquisition request is generated in the acquisition request step and causing the sever to transmit the information to the gateway apparatus via a radio data communication network; and
the transfer step of temporarily storing information transmitted in the information transmission step and causing the gateway apparatus to transfer the information to the client. - View Dependent Claims (11, 12, 13)
