Abstract

In a device information management system in which a management server for managing device information and various devices are connected, a plurality of different types of device information is transmitted to the management server at predetermined timings, respectively. In a device information management system in which a management server for managing device information and various devices are connected, a request to transmit the device information to the management server is transmitted to another device and the device information of the requesting device is transmitted to the management server in accordance with the request.

Claims

1. A network device that communicates with a server apparatus and sends a write request to the server apparatus without receiving a request from the server apparatus, said network device comprising:

a request unit constructed to make a request for registering, updating or deleting device information of said network device in a predetermined area of the server apparatus, an access right being required to write into the predetermined area;

a specifying unit constructed to specify a substitute device that registers, updates or deletes the device information of said network device; and

a setting unit constructed to set the access right such that the substitute device specified by said specifying unit is enabled to register, update or delete the device information of said network device in the predetermined area of the server apparatus.

2. A network device according to claim 1, wherein the specified substitute device registers, updates or deletes the device information of said network device when said network device cannot update the device information.

3. A network device according to claim 1, further comprising a detection unit constructed to detect an abnormality that has occurred in said network device, wherein the specified substitute device registers, updates or deletes the device information of said network device when said detection unit detects the abnormality.

4. A network device according to claim 3, wherein the abnormality is a power shut-off status.

5. A network device according to claim 3, wherein the abnormality is a trouble.

6. A network device according to claim 1, wherein when a device accepts registering or updating the device information of said network device, said specifying unit specifies the device as the substitute device.

7. A server apparatus for communication with a network apparatus that sends a write request to said server apparatus without receiving a request from said server apparatus, said server apparatus comprising:

a reception unit constructed to receive a request for registering, updating or deleting device information of the network device in a predetermined area of said server apparatus, an access right being required to write into the predetermined area;

a discrimination unit constructed to discriminate, based on the request received by said reception unit, whether the network device has authority to register, update or delete the device information of the network device in the predetermined area of said server apparatus; and

an execution unit constructed to register, update or delete the device information of the network device in the predetermined area of said server apparatus, based on the request received by said reception unit, if said discrimination unit discriminates that the network device has the authority.

8. A server apparatus according to claim 7, further comprising an informing unit constructed to inform execution results provided by said execution unit.

9. A computer implemented method for a network device that communicates with a server apparatus and sends a write request to the server apparatus without receiving a request from the server apparatus, comprising:

a processor performing the steps of;

a request step of requesting to register, update or delete device information of said network device in a predetermined area of the server apparatus, an access right being required to write into the predetermined area;

a specifying step of specifying a substitute device that registers, updates or deletes the device information of said network device; and

a setting step of setting the access right such that the substitute device specified by said specifying step is enabled to register, update or delete the device information of said network device in the predetermined area of the server apparatus.

10. A method according to claim 9, wherein the specified substitute device registers, updates or deletes the device information of said network device when said network device cannot update the device information.

11. A method according to claim 9, further comprising a detection step of detecting an abnormality that has occurred in said network device, wherein the specified substitute device registers, updates or deletes the device information of said network device when said detection step detects the abnormality.

12. A method according to claim 11, wherein the abnormality is a power shut-off status.

13. A method according to claim 11, wherein the abnormality is a trouble.

14. A method according to claim 9, wherein when a device accepts registering or updating the device information of said network device, said specifying step specifies the device as the substitute device.

15. A computer implemented method for a server apparatus for communication with a network apparatus that sends a write request to said server apparatus without receiving a request from said server apparatus, comprising:

a processor performing the steps of;

a reception step of receiving a request for registering, updating or deleting device information of the network device in a predetermined area of said server apparatus, an access right being required to write into the predetermined area;

a discrimination step of discriminating, based on the request received by said reception step, whether the network device has authority to register, update or delete the device information of the network device in the predetermined area of said server apparatus; and

an execution step of executing to register, update or delete the device information of the network device in the predetermined area of said server apparatus, based on the request received by said reception step, if said discrimination step discriminates that the network device has the authority.

16. A method according to claim 15, further comprising an informing step of informing execution results provided by said execution step.

17. A computer-readable storage medium on which is stored a computer program that implements a method for a network device that communicates with a server apparatus and sends a write request to the server apparatus without receiving a request from the server apparatus, said method comprising:

a request step of requesting to register, update or delete device information of said network device in a predetermined area of the server apparatus, an access right being required to write into the predetermined area;

a specifying step of specifying a substitute device that registers, updates or deletes the device information of said network device; and

a setting step of setting the access right such that the substitute device specified by said specifying step is enabled to register, update or delete the device information of said network device in the predetermined area of the server apparatus.

18. A computer-readable storage medium on which is stored a computer program that implements a method for a server apparatus for communication with a network apparatus that sends to a write request to said server apparatus without receiving a request from said server apparatus, said method comprising:

a reception step of receiving a request for registering, updating or deleting device information of the network device in a predetermined area of said server apparatus, an access right being required to write into the predetermined area;

a discrimination step of discriminating, based on the request received by said reception step, whether the network device has authority to register, update or delete the device information of the network device in the predetermined area of said server apparatus; and

an execution step of executing to register, update or delete the device information of the network device in the predetermined area of said server apparatus, based on the request received by said reception step, if said discrimination step discriminates that the network device has the authority.
