Abstract
A first information processing apparatus receives file information from a second information processing apparatus when the information processing apparatus switches into a power saving state. If the first information processing apparatus receives, from a third information processing apparatus, a file process request packet in terms of a file stored in the second information processing apparatus, the first information processing apparatus stores the received file process request packet. When the second information processing apparatus returns into the normal power state, the first information processing apparatus transfers the stored file process request packet to the second information processing apparatus.
Claims14
An information processing system comprising a first information processing apparatus and a second information processing apparatus capable of communicating with the first information processing apparatus,
- the first information processing apparatus comprising:
- a first receiving unit configured such that when the second information processing apparatus having a storage unit capable of storing a file switches into a power saving state in which electric power is cut off at least to the storage unit, the first receiving unit receives file information indicating an attribute of the file stored in the storage unit from the second information processing apparatus;
- a second receiving unit configured to receive an acquisition request for acquiring the file information;
- a first transmitting unit configured to, when the second receiving unit receives the acquisition request, transmit the file information received by the first receiving unit to a sender of the acquisition request;
- a third receiving unit configured to, when the second information processing apparatus is in the power saving state, receive a process request in terms of the file stored in the storage unit of the second information processing apparatus;
- an updating unit configured to, when the third receiving unit receives the process request, update the file information in accordance with the process request received by the third receiving unit;
- and
- a second transmitting unit configured to transmit the process request received by the third receiving unit to the second information processing apparatus when the second information processing apparatus switches from the power saving state into a normal power state in which electric power is supplied at least to the storage unit,
- the second information processing apparatus comprising:
- a third transmitting unit configured to transmit the file information to the first information processing apparatus when the second information processing apparatus switches into the power saving state;
- a fourth receiving unit configured to receive the process request transmitted from the second transmitting unit when the second information processing apparatus switches from the power saving state into the normal power state;
- and
- a control unit configured to perform a control operation such that the file stored in the storage unit is processed in accordance with the process request received by the fourth receiving unit.

An information processing method in an information processing system including a first information processing apparatus and a second information processing apparatus capable of communicating with the first information processing apparatus, the method comprising:
- in the second information processing apparatus, when the second information processing apparatus having a storage unit capable of storing a file switches into a power saving state in which electric power is cut off at least to the storage unit, transmitting file information indicating an attribute of the file stored in the storage unit to the first information processing apparatus from the second information processing apparatus;
- in the first information processing apparatus, receiving an acquisition request for acquiring the file information;
- if the first information processing apparatus receives the acquisition request, transmitting the file information from the first information processing apparatus to a sender of the acquisition request;
- in the first information processing apparatus, receiving a process request in terms of the file stored in the storage unit of the second information processing apparatus when the second information processing apparatus is in the power saving state;
- in the first information processing apparatus, if the process request is received, updating the file information based on the process request received;
- in the first information processing apparatus, transmitting the process request from the first information processing apparatus to the second information processing apparatus when the second information processing apparatus switches from the power saving state into the normal power state in which electric power is supplied at least to the storage unit;
- and
- in the second information processing apparatus, performing a control operation such that the file stored in the storage unit is processed in accordance with the process request received from the first information processing apparatus.
