Abstract

An apparatus operates in at least a first mode and a second mode consuming less power than the first mode, and stores information indicating specific data to be responded without shifting from the second mode to the first mode, the data being received from a network during an operation in the second mode. Data received from the network during an operation in the first mode is determined whether to be the specific data indicated by the information stored by a storage unit. When the data is the specific data, a shift from the first mode to the second mode after responding to the received data is faster than when the data is not the specific data.

Claims

1. An apparatus operating in at least a first mode and a second mode consuming less power than the first mode, the apparatus comprising:

a storage unit configured to store information indicating specific data to be responded without shifting from the second mode to the first mode, the data being received from a network during an operation in the second mode;

a reception unit configured to receive data from the network during an operation in the first mode;

a determination unit configured to determine whether the received data is the specific data; and

a control unit configured to control such that a shift from the first mode to the second mode after responding to the received data is faster in a case the data is the specific data than in the case the data is not the specific data.

2. The apparatus according to claim 1, further comprising a shift unit configured to shift to the second mode in response to a lapse of transition time during which no operation is made in the apparatus in the first mode.

3. The apparatus according to claim 1, further comprising a determining unit configured to determine whether data received from the network during an operation in the second mode is the specific data,

Wherein, if the data is the specific data, a response is made to the specific data without shifting to the first mode from the second mode, and if the data is not the specific data, a response is made to the data upon shifting to the first mode from the second mode.

4. The apparatus according to claim 1, further comprising a main control unit and a sub-control unit of which power supply are controlled by a power source control unit,

wherein the first mode is in a state that the power is supplied to the main control unit and the sub-control unit, and the second mode is in a state that the power is not supplied to the main control unit while the power is supplied to the sub-control unit.

5. The apparatus according to claim 1, wherein information stored in the storage unit is an object identifier (OID) of a specific management information base (MIB) in a simple network management protocol (SNMP).

6. The apparatus according to claim 1, wherein information stored in the storage unit is information indicating a specific method in a simple object access protocol (SOAP).

7. A method for controlling an apparatus operating in at least a first mode and a second mode consuming less electric power than the first mode, the method comprising:

storing, in a storage unit, information indicating specific data to be responded without shifting from the second mode to the first mode, the data being received from a network during an operation in the second mode;

receiving data from the network during an operation in the first mode;

determining whether the received data is specific data indicated by the stored information; and

controlling such that a shift from the first mode to the second mode after responding to the received data is faster in the case the data is the specific data than in the case the data is not the specific data.

8. The method according to claim 7, further comprising shifting to the second mode in response to a lapse of transition time during which no operation is made in the apparatus in the first mode.

9. The method according to claim 7, further comprising determining whether data received from the network during an operation in the second mode is the specific data,

wherein, if the data is the specific data, a response is made to the specific data without shifting to the first mode from the second mode, and if the data is not the specific data, a response is made to the data upon shifting to the first mode from the second mode.

10. The method according to claim 7, further comprising controlling power supply of a main control unit and a sub-control unit of the apparatus,

wherein the first mode is in a state that the power is supplied to the main control unit and the sub-control unit, and the second mode is in a state that the power is not supplied to the main control unit while the power is supplied to the sub-control unit.

11. The method according to claim 7, wherein the stored information is an object identifier (OID) of a specific management information base (MIB) in a simple network management protocol (SNMP).

12. The method according to claim 7, wherein the stored information stored is information indicating a specific method in a simple object access protocol (SOAP).

13. A computer-readable storage medium storing a computer program of instructions for causing a computer to perform a method comprising:

storing, in a storage unit, information indicating specific data to be responded without shifting from the second mode to the first mode, the data being received from a network during an operation in the second mode;

receiving data from the network during an operation in the first mode;

determining whether the received data is specific data indicated by the stored information; and

controlling such that a shift from the first mode to the second mode after responding to the received data is faster in the case the data is the specific data than in the case the data is not the specific data.

14. The computer-readable storage medium according to claim 13, further comprising shifting to the second mode in response to a lapse of transition time during which no operation is made in the apparatus in the first mode.

15. The computer-readable storage medium according to claim 13, further comprising determining whether data received from the network during an operation in the second mode is the specific data,

wherein, if the data is the specific data, a response is made to the specific data without shifting to the first mode from the second mode, and if the data is not the specific data, a response is made to the data upon shifting to the first mode from the second mode.

16. The computer-readable storage medium according to claim 13, further comprising controlling power supply of a main control unit and a sub-control unit of the apparatus,

wherein the first mode is in a state that the power is supplied to the main control unit and the sub-control unit, and the second mode is in a state that the power is not supplied to the main control unit while the power is supplied to the sub-control unit.

17. The computer-readable storage medium according to claim 13, wherein the stored information is an object identifier (OID) of a specific management information base (MIB) in a simple network management protocol (SNMP).

18. The computer-readable storage medium according to claim 13, wherein the stored information stored is information indicating a specific method in a simple object access protocol (SOAP).
