Abstract

A presentity service client has a presentity that issues presence information to a presence service and a watcher which observes presence information for other presentities; a presence change rule holding part holds a presence change rule; and a presence calculating part changes the presence information for the presentity, using as a trigger a change in presence information of other presentities, based on the presence information of other presentity acquired by the watcher and in accordance with the presence change rule held by a presence change rules holding part.

Claims

1. A presence system, comprising:

presentities that provide presence information indicating at least the state of own entity;

subscribers that observe said presence information; and

a presence service that delivers said presence information received from said presentities to said subscribers;

wherein said presentities are provided with a notification part which notifies said presence information to specific subscribers only.

2. The presence system as set forth in claim 1, wherein

said presentities include an element which derives said specific subscribers in accordance with a notification destination determination rule held by said presentities,

wherein said notification part notifies said presence information to said specific subscribers thus derived only.

3. The presence system as set forth in claim 1, wherein

said presentities include an element which derives said specific subscribers in accordance with a notification destination determination rule that includes a notification condition designated by said subscribers,

wherein said notification part notifies said presence information to said specific subscribers thus derived only.

4. The presence system as set forth in claim 1, wherein

said subscribers determine subscribers to which said presence information is to be notified in accordance with the order in which said subscribers have performed subscription.

5. The presence system as set forth in claim 1, wherein

subscribers to which said presence information is to be notified are determined according to the attributes of said subscribers.

6. The presence system as set forth in claim 1, wherein

subscribers to which said presence information is to be notified are determined according to the presences for said presentities.

7. The presence system as set forth in claim 1, wherein

when notifying said presence information, information for authenticating that the destination subscribers are said specific subscribers is added.

8. The presence system as set forth in claim 7, wherein

said information for authenticating is information with a pre-set time limit.

9. The presence system as set forth in claim 1, wherein

at least any of instant messaging, e-mail, or telephone notification is included as a means of notifying said presence information.

10. A presence notification destination controlling method, wherein

said method is a presence notification destination controlling method for a presence system comprising presentities that provides presence information indicating at least the state of own entity;

subscribers that observe said presence information; and

a presence service that delivers said presence information received from said presentities to said subscribers;

and comprising on the side of said presentities the step of notifying said presence information to specific subscribers only.

11. The presence notification destination controlling method as set forth in claim 10, wherein

the step of deriving said specific subscribers in accordance with a notification destination determination rule held by said presentities is included on the side of said presentities,

wherein the step of notifying said presence information notifies said presence information to said specific subscribers thus derived only.

12. The presence notification destination controlling method as set forth in claim 10, wherein

the step of deriving said specific subscribers in accordance with a notification destination determination rule that includes a notification condition designated by said subscribers is included on the side of said presentities,

wherein the step of notifying said presence 100 information notifies said presence information to said specific subscribers thus derived only.

13. The presence notification destination controlling method as set forth in claim 10, wherein

said subscribers determine subscribers to which said presence information is to be notified in accordance with the order in which said subscribers have performed subscription.

14. The presence notification destination controlling method as set forth in claim 10, wherein

subscribers to which said presence information is to be notified are determined according to the attributes of said subscribers.

15. The presence notification destination controlling method as set forth in claim 10, wherein

subscribers to which said presence information is to be notified are determined according to the presences for said presentities.

16. The presence notification destination controlling method as set forth in claim 10, wherein

when notifying said presence information, information for authenticating that the destination subscribers are said specific subscribers is added.

17. The presence notification destination control method as set forth in claim 16, wherein

said information for authenticating is information with a pre-set time limit.

18. The presence notification destination controlling method as set forth in claim 10, wherein

the step of notifying said presence information notifies said presence information using a means including any of instant messaging, e-mail, or telephone notification.

19. A presence notification destination controlling program, wherein

said program is a presence notification destination controlling program for a presence system comprising presentities that provides presence information indicating at least the state of own entity;

subscribers that observe said presence information; and

a presence service that delivers said presence information received from said presentities to said subscribers;

and comprising capabilities of having a computer execute a function of notifying said presence information to specific subscribers only.
