Abstract

The present invention discloses a method for providing presence information, a watcher, a presence server, a presence system and a presentity. It enables the provisioning of history and future presence information, while the prior arts can provide only presence information corresponding to the current time. The method provided by the present invention includes: setting time elements of presence information; recording relevant time information of presence information in the time elements; providing the watcher with presence information together with relevant time information.

Claims

1. A method for providing presence information, comprising:

recording time information in time elements of presence information;

providing a watcher client with presence information and the time information of presence information.

2. The method of claim 1, wherein the time information comprises start time and/or end time;

the presence information comprises first presence information, second presence information; and

recording time information in a time element of presence information comprises;

receiving second presence information of presentity client;

storing first presence information, recording the time of receiving second presence information as the end time of the first presence information, and recording the time of receiving the second presence information as the start time of the second presence information.

3. The method of claim 1, wherein the presence information comprises at least one element, and the providing the time information of presence information comprises:

providing time information of each element of the presence information.

4. The method of claim 1, further comprising:

displaying, by the watcher client, the time information of the presence information and the presence information.

5. The method of claim 4, wherein the presence information comprises at least one piece of information, and displaying the time information of presence information and the presence information comprises:

displaying the time information of each piece of the presence information and multiple pieces of the presence information.

6. The method of claim 5, wherein displaying the time information of the presence information and the presence information comprises:

displaying the latest multiple pieces of presence information of a presentity received by the watcher client according to a preset value and the time information of each presence information, if the number of pieces of presence information is more than the number of the preset value.

7. The method of claim 1, further comprising:

receiving, by a presence server, an obtaining presence information request comprising a time condition;

wherein the presence information provided by the presence information meets the time condition.

8. The method of claim 2, further comprising:

sorting presence information according to the start time or end time of multiple pieces of presence information of a presentity.

9. A watcher client, comprising:

a receiving module, receiving presence information carrying time information in time elements of presence information;

a display module, displaying the presence information and the time information of the presence information.

10. The watcher client of claim 9, further comprising:

a storage module, storing the presence information and the time information of the presence information and providing the display module with the presence information and time information of the presence information.

11. The watcher of claim 9, wherein the display module is further used for generating graphs according to presence information and time information of presence information, and displaying the graphs on the watcher client.

12. The watcher client of claim 11, wherein the graphs take presence information and the time information of presence information as x-coordinate and y-coordinate.

13. The watcher client of claim 11, wherein the presence information is geographic location information and the graphs are maps where time information is marked at relevant geographic location points.

14. The watcher client of claim 9, wherein the time information comprises start time and end time, the presence information comprises first presence information and second presence information;

and

the receiving module, further for storing the first presence information and recording the time of receiving the second presence information as the end time of the first presence information, and as the start time of the second piece of presence information if the time elements in the presence information are black.

15. The watcher client of claim 11, further comprising:

configuration information, including presentity identifiers and/or presence information identifiers;

wherein the storage module determines whether to store the time information of the presence information according to presentity identifiers and/or presence information identifiers.

16. A presence server, comprising:

a receiving module, receiving presence information;

a time information processing module, recording time information of the presence information;

a distributing module, distributing the presence information and time information of the presence information provided.

17. The presence server of claim 16, wherein the time information comprises start time and end time and the presence information comprises first presence information and second presence information;

and the time information processing module stores first presence information and records the time of receiving the second presence information as the end time of the first piece of presence information, and as the start time of the second presence information.

18. The presence server of claim 16, wherein the receiving module further receives a obtaining presence information request, and the obtaining presence information request includes time condition;

the presence server further comprising;

a query module, providing presence information and time information of the presence information that meet the time condition upon receiving the obtaining presence information request.

19. The presence server of claim 16, wherein the presence server further comprises configuration information including presentity identifiers and/or presence information identifiers;

and

the time information processing module further determines whether to store the time information of presence information according to presentity identifiers of and/or presence information identifiers.

20. The presence server of claim 16, wherein the distributing module distributes the all presence information of a presentity and time information of each presence information received by the presence server during the time when the watcher client is offline or does not subscribe to the presence information of the presentity.

21. A presentity client, comprising:

a setup unit, setting time information of presence information in time elements of the presence information;

a publishing unit, publishing the presence information carrying the time information.
