Abstract

An information processing device that communicates with a server on Internet over a local network, having: a session establishing part that establishes a session that enables a communication with said server over said local network; a periodic communicating part that establishes periodic communications at a predetermined time interval with said server to maintain said session; a power controller that stops a power supply to said periodic communicating part if a predetermined condition to enter sleep mode is met; and a substitute requesting part that requests another device installed on said local network to establish the periodic communication with said server that should be established by said periodic communicating part for said periodic communicating part when said power controller enables said information processing device to enter sleep mode.

First claim

What is claimed is:

1. An information processing device that communicates with a server on Internet over a local network, comprising:
a hardware processor that is configured to:
establish a session that enables a communication with said server over said local network;
establish periodic communications at a predetermined time interval with said server to maintain said session; and
wherein (1) when multiple other devices are installed on said local network that are establishing sessions that enable the periodic communications with said server, and (2) when the information processing device is going into sleep mode after a condition to enter the sleep mode is met, said hardware processor requests one of the multiple other devices that has the longest time left until entering the sleep mode to establish the periodic communications with said server for said information processing device as a substitute for said information processing device.

2. The information processing device according to claim 1 , wherein the hardware processor is further configured to:
establish substitute periodic communications with said server that should be established by yet another of the multiple other devices for the another device when the one device on said local network requests to establish the periodic communication for it.

3. The information processing device according to claim 2 , wherein
said hardware processor establishes the substitute periodic communications which are requested by the one of the multiple other devices at the same point in time when said information processing device establishes the periodic communications with said server.

4. The information processing device according to claim 2 , wherein
said hardware processor requests the one device on said local network to establish both of the periodic communications established by said information processing device and the substitute periodic communications requested by the one of the multiple other devices when said hardware processor serves as a substitute to establish the periodic communications with said server and said information processing device goes into the sleep mode.

5. The information processing device according to claim 1 , wherein
said hardware processor sends substitute information showing that the request to establish the periodic communications with said server for said information processing device that is sent to said one of the other multiple devices is also sent to at least another device that is establishing the session that enables the communications with said server after sending the request to be the substitute for said information processing device to establish the periodic communications with said server to said one of the other devices.

6. The information processing device according to claim 1 , wherein
said hardware processor makes an inquiry about time left until entering the sleep mode at each of the multiple other devices that are establishing the sessions that enable the communications with said server, and selects one of the multiple other devices based on responses from the multiple other devices.

7. The information processing device according to claim 1 , wherein
said hardware processor makes the inquiry at said server and requests the one device specified by said server to establish the periodic communication with said server for said information processing device when said information processing device goes into sleep mode.

8. The information processing device according to claim 1 , further comprising:
a power controller that stops establishing periodic communications at a predetermined time interval with said server to maintain said session if a predetermined condition to enter sleep mode is met.

9. An information processing device that communicates with a server on Internet over a local network, comprising:
a hardware processor that is configured to:
establish a session that enables a communication with said server over said local network;
establish periodic communications at a predetermined time interval with said server to maintain said session; and
wherein (1) when multiple other devices are installed on said local network that are establishing sessions that enable the periodic communications with said server, and (2) when the information processing device is going into sleep mode after a condition to enter the sleep mode is met, said hardware processor requests another device of the multiple other devices that is establishing a session that enables communication with another server, which is different from said server, to establish the periodic communications with said server for said information processing device.

10. The information processing device according to claim 9 , wherein
said hardware processor makes the inquiry whether or not each of the multiple other devices is establishing the session that enables the communication with another server, different from said server, at each of the multiple other devices establishing the session that enables the communication with said server, and selects one of the multiple other devices based on responses from the multiple other devices.

11. The information processing device according to claim 9 , further comprising:
a power controller that stops establishing periodic communications at a predetermined time interval with said server to maintain said session if a predetermined condition to enter sleep mode is met.

12. An information processing system, comprising:
a first information processing device installed on a local network;
a server on Internet capable of communicating with said first information processing device over said local network, wherein
said first information processing device includes:
a first hardware processor configured to:
establish a first session that enables a communication with said server over said local network, and establishes periodic communications at a predetermined time interval with said server to maintain the first session; and
when the information processing system includes at least two other information processing devices on said local network, other than the first information processing device, and the at least two other information processing devices are each establishing a session that allows the communications with said server, said first hardware processor requests one of the more than two other information processing devices, that has a longest left time until going into sleep mode, for establishing the periodic communications with said server.

13. A server connected to Internet and capable of communicating with multiple information processing devices, comprising:
a hardware processor configured to:
establish a separate session with each of said multiple information processing devices, and maintain said session by receiving periodic communications from each of said information processing devices;
determine a substitute device that establishes the periodic communications for one of said multiple information processing devices from among the other multiple information processing devices that are establishing said sessions except for said one of said multiple information processing devices when an inquiry about the substitute device that establishes the periodic communications for said one of said multiple information processing devices is received from said one of said multiple information processing devices; and
manage history information relating to a history of communications with each of said information processing devices, wherein
said hardware processor determines a device that has a shortest elapsed time after the previous periodic communications
