Method for providing absence information

1. A method for providing absence information for a telecommunication subscriber, the method comprising:

creating and acquiring the absence information regarding a first subscriber terminal;

sending the absence information regarding the first subscriber terminal to a switching node and storing the absence information in the switching node; and

sending the absence information regarding the first subscriber terminal to a second subscriber terminal, such that the absence information is continuously available at the second terminal, wherein

absence text and station guarding service features are used when creating and storing the absence information.

2. The method as claimed in claim 1 , further comprising:

sending a request message to the switching node by the second terminal; and, after receiving the request message,

sending current absence information regarding the first subscriber terminal to the second terminal by the switching node.

3. The method as claimed in claim 1 , further comprising:

sending a request message to the switching node by the second terminal; and, after receiving the request message,

sending current absence information regarding the first subscriber terminal to the second terminal by the switching node at specified time intervals.

4. The method as claimed in claim 1 , further comprising:

sending a request message to the switching node by the second terminal; and, after receiving the request message;

sending the absence information regarding the first subscriber terminal to the second terminal by the switching node if the absence information has changed.

5. The method as claimed in claim 1 , wherein the absence information regarding the first subscriber terminal is automatically acquired at the second terminal.

6. The method as claimed in claim 2 , wherein the absence information regarding the first subscriber terminal is automatically acquired at the second terminal.

7. The method as claimed in claim 3 , wherein the absence information regarding the first subscriber terminal is automalically acquired at the second terminal.

8. The method as claimed in claim 4 , wherein the absence information regarding the first subscriber is automatically acquired at the second terminal.

9. The method as claimed in claim 1 , wherein the absence information which has been sent is displayed at the second terminal.

10. The method as claimed in claim 1 , wherein the absence information is regularly undated at the second terminal.

11. The method as claimed in claim 1 , wherein further service features are used for creating and storing the absence information.

12. The method as claimed in claim 1 , wherein the switching node includes storage for subscriber list from which absence information is sent to the second terminal.

13. The method as claimed in claim 1 , wherein the switching node sends the absence information to one second terminal.

14. The method as claimed in claim 1 , wherein the second terminal is an external terminal relative to the first subscriber terminal, having a network connection to the switching node.

15. The method as claimed in claim 14 , wherein the network connection includes the Internet.

16. The method as claimed in claim 14 , wherein a first assignment table is used for transforming the absence information regarding the external terminal from an absence information format of the external terminal into an absence information format of the switching node.

17. The method as claimed in claim 14 , wherein a second assignment table is used for transforming the absence information from the absence information format of the switching node into the absence information format of the external terminal.

18. The method as claimed in claim 14 , wherein standard protocols are used for sending the absence information between the first and second terminals.

19. The method as claimed in claim 18 , wherein the Session Initiation Protocol (SIP) is used as a standard protocol for sending the absence information between the terminals.
