Abstract
An increase in communication load in a network due to increasing messages for requesting information is suppressed. When a message for requesting information and a response message thereto are sent and received between a communication device (N1-Nn) that is an information requester and an information provider (Nx) on a network (NW) via a communication device (1), the communication device (1) stores the information acquired from the response message in a response information storage section (4), and when any communication device requests at least part of the same information, a control section (5) creates a response message including the requested information and responds.
Claims18
A communication system in which a first communication device is connected to a network, wherein the first communication device is connected to a plurality of second communication devices,
- wherein when a message for requesting information and a response message thereto are sent and received between a second communication device that is an information requester and an information provider on the network via the first communication device, the first communication device stores the information acquired from the response message, and when any second communication device makes a request to the information provider for at least part of the same information, the first communication device creates a response message including the requested information to respond.
A gateway device disposed between a network and a plurality of communication devices, comprising:
- a detector that detects a message for requesting information and a response message thereto sent and received between a communication device that is an information requester and an information provider on the network;
- a storage section that stores the information acquired from the response message;
- and
- a controller that, when any communication device makes a request to the information provider for at least part of the same information, creates a response message including the requested information that is stored in the storage section, and responds.
A communication control method in a communication device disposed between a network and a plurality of base stations, comprising:
- detecting a message for requesting information and a response message thereto sent and received between a base station that is an information requester and an information provider on the network;
- storing the information acquired from the response message in a storage section;
- and
- when any base station makes a request to the information provider for at least part of the same information, creating a response message including the requested information that is stored in the storage section, and responding.
