Gateway apparatus, communication apparatus, apparatus co-operation network system, and apparatus co-operation method
View Patent ↗A gateway apparatus for allowing a plurality of apparatuses on a first network to co-operate with each other includes: a message monitoring unit which monitors messages communicated on the first network, and detects an apparatus discovery message for discovering an apparatus that satisfies an arbitrary requirement; an activation state managing unit which checks whether at least one target apparatus among the apparatuses that satisfies the requirement indicated by the apparatus discovery message is in an activated state for communication on the first network; a predicted activation time determining unit which determines a predicted activation time predicted as required to activate the at least one target apparatus; and a proxy response unit which transmits, in proxy of the at least one target apparatus, a response message including information indicating the predicted activation time when the at least one target apparatus is not in an activated state.
1. A communication apparatus which co-operates with apparatuses on a first network, the communication apparatus comprising:
an apparatus co-operation processing unit configured to transmit, to the apparatuses on the first network, a first apparatus discovery message indicating an arbitrary requirement, and receive a plurality of response messages in response to the first apparatus discovery message, the plurality of response messages indicating a plurality of target apparatuses that satisfy the arbitrary requirement and include a first target apparatus, the first target apparatus indicated by a first response message included in the plurality of response messages; and
a notifying unit configured to execute a process of notifying a user of a predicted activation time in association with the first target apparatus, when the first response message includes the predicted activation time, the predicted activation time being a time predicted as required to activate the first target apparatus,
wherein the apparatus co-operation processing unit is further configured to transmit, to the apparatuses on the first network, a second apparatus discovery message for activating the first target apparatus, when the first target apparatus is selected by the user based on the predicted activation time from among the plurality of target apparatuses.
2. A communication apparatus which co-operates with apparatuses on a first network, the communication apparatus comprising
an apparatus co-operation processing unit configured to:
transmit, to the apparatuses on the first network, a first apparatus discovery message indicating an arbitrary requirement;
receive a plurality of response messages in response to the first apparatus discovery message, the plurality of response messages indicating a plurality of target apparatuses that satisfy the arbitrary requirement and include a first target apparatus, the first target apparatus indicated by a first response message included in the plurality of response messages;
transmit, to the apparatuses on the first network, a second apparatus discovery message for activating the first target apparatus, when the first target apparatus is selected from among the plurality of target apparatuses; and
when the first response message includes a predicted activation time which is a time predicted as required to activate the first target apparatus, execute a process of transmitting, to the first target apparatus, a message for co-operation with the first target apparatus, after the predicted activation time elapses from a reception time of the response message in response to the second apparatus discovery message.
