Abstract

An information processing device connected to a terminal via a network includes a memory that stores inquiry packet data received from the terminal in association with response packet data to respond to the inquiry packet data; control circuitry to control an operation mode of the information processing device, wherein when the information processing device is in an energy conservation mode, the control circuitry determines whether or not the received inquiry packet data is new inquiry packet data determined by new network protocols, when the received inquiry packet data is the new inquiry packet data, the control circuitry reinstates the information processing device, in conjunction with a transmission for the response packet data generated by the information processing device to the terminal, and stores the received inquiry packet data and the generated response packet data to the memory.

First claim

1. An information processing device connected to a terminal via a network, the information processing device comprising:
a packet memory that stores inquiry packet data received from the terminal in association with response packet data to respond to the inquiry packet data;
control circuitry configured to control an operation mode of the information processing device, wherein
when the information processing device is in an energy conservation mode, the control circuitry is configured to determine whether or not the received inquiry packet data is new inquiry packet data determined by new network protocols,
when the received inquiry packet data is the new inquiry packet data, the control circuitry is configured to reinstate the information processing device, in conjunction with a transmission for the response packet data generated by the information processing device to the terminal, and store the received inquiry packet data and the generated response packet data to the packet memory,
when the received inquiry packet data is not the new inquiry packet data, the control circuitry is configured to generate new response packet data based on the response packet data stored in the packet memory, and transmit the new response packet data to the terminal, and
when memory capacity of the packet memory is full, the control circuitry is further configured to discard inquiry packet data and response packet data, and store the received inquiry packet data and the generated packet data into the packet memory.

2. The information processing device according to claim 1 , wherein
the control circuitry is further configured to store the received inquiry packet data, the new response packet data corresponding to the inquiry packet data, and a number of transmission times for a response of the new response packet data in association with each other in the packet memory, and discard one inquiry packet data and a corresponding response packet data stored in the packet memory based on the number of response times.

3. The information processing device according to claim 1 , wherein
the control circuitry is further configured to store the received inquiry packet data, the new response packet data corresponding to the inquiry packet data, and a reception time interval that receives a same kind of the inquiry packet data in association with each other into the packet memory, and the control circuitry is further configured to discard one inquiry packet data and the response packet data stored in the packet memory based on the reception time interval.

4. The information processing device according to claim 1 , wherein
before the information processing device acts in the energy conservation mode, the control circuitry is configured to store, into the packet memory, inquiry packet data determined by an expected status information in association with response packet data to respond to the inquiry packet data.

5. An information processing system, comprising:
a network;
a terminal connected with the network; and
the information processing device according to claim 1 , wherein the information processing system is connected with the terminal via the network.

6. An information processing device connected to a terminal via a network, the information processing device comprising:

when the received inquiry packet data is not the new inquiry packet data, the control circuitry is configured to generate new response packet data based on the response packet data stored in the packet memory, and transmit the new response packet data to the terminal, and
wherein the control circuitry is further configured to discard the inquiry packet data and the response packet data corresponding to a smallest response number from the packet memory.

7. An information processing device connected to a terminal via a network, the information processing device comprising:
a packet memory that stores inquiry packet data received from the terminal in association with response packet data to respond to the inquiry packet data;
control circuitry configured to control an operation mode of the information processing device, wherein
when the information processing device is in an energy conservation mode, the control circuitry is configured to determine whether or not the received inquiry packet data is new inquiry packet data determined by new network protocols,
when the received inquiry packet data is the new inquiry packet data, the control circuitry is configured to reinstate the information processing device, in conjunction with a transmission for the response packet data generated by the information processing device to the terminal, and store the received inquiry packet data and the generated response packet data to the packet memory,
when the received inquiry packet data is not the new inquiry packet data, the control circuitry is configured to generate new response packet data based on the response packet data stored in the packet memory, and transmit the new response packet data to the terminal, and
wherein the control circuitry is further configured to discard the inquiry packet data and the response packet data corresponding to a longest reception time interval from the packet memory.

8. An information processing method in an information processing device connected with a terminal via a network, the information processing device including a packet memory that stores inquiry packet data received from the terminal device and response packet data to response to the inquiry packet data in association with the inquiry packet data, and control circuitry that controls an operation mode of the information processing device, when the information processing device is acting in an energy conservation mode, the information processing method comprising:
determining whether the received inquiry packet data is a new inquiry packet data determined by new network protocols;
