Relay device, communication system, and relaying method
First Claim
1. A relay device, for connecting plural independent wireless networks and which functions as a wireless access point, for relaying communication between an information request device which requests information and an information providing device which provides requested information, the relay device comprising:
- an interface configured to receive a signal transmitted by the information request device;
first circuitry configured to detect, from the signal, a connection request, a disconnection request, or an authentication success; and
second circuitry configured to, when the first circuitry detects the connection request, the disconnection request, or the authentication success, control capacity of storage areas included in a storage device for storing information which is requested by the information request device, sent by the information providing device, and to be sent to the information request device, or an available range of storage for storing the information in the storage device, whereina whole storage area in the storage device is divided into a plurality of the storage areas different from one another allocated to the respective networks; and
when the interface receives an acquisition request for information from an information request device belonging to a first network, the second circuitry searches only a storage area that is allocated to the first network for the information requested by the information request device belonging to the first network in order to send the information as a response.

Abstract
According to one embodiment, a relay device that relays communication between an information request device which requests information and an information providing device which provides requested information. The relay device includes an interface to receive a signal transmitted by the information request device. The relay device includes a first circuitry to perform, using the signal, at least one of connection management of a network, authentication of the information request device, and authentication of a user of the information request device. The relay device includes a second circuitry to control allocation of storage areas included in a storage device, or an available range within which information saved in the storage area is able to be provided, when the first circuitry detects establishment of a connection to the network, disconnection of the connection, an authentication result, or a lapse of a valid connection time period.
