Abstract

A system and method to provide a presence user agent (207) capable of receiving tag identifiers from a tagging sensor (205) and possibly tag statuses. The presence user agent (207) may send the tag identifier, tagging sensor identifier, and other associated data to a Session Initiation Protocol Presence Server (201). SIP Presence Server (201) may send a message based on the tag identifier and tagging sensor identifier to a requesting entity (211).

Claims

1. A method for communicating presence information to a subscriber comprising the steps of:

receiving a register message having a presence comprising at least one first portion and at least one second portion;

receiving a subscribe message having at least one criterion;

matching the at least one criterion to the presence; and

transmitting a notify message having the at least one first portion to the subscriber.

2. The method of claim 1 wherein the first portion comprises at least one tag portion.

3. The method of claim 2 wherein the at least one criterion comprises at least one tag criterion and at least one tagging sensor criterion.

4. The method of claim 3 wherein the step of receiving a register message comprises:

receiving the register message at a first domain, the register message originating from a second domain.

5. The method of claim 3 wherein the register message comprises at least one session initiation protocol field.

6. The method of claim 3 wherein the register message comprises a domain.

7. The method of claim 3 wherein the step of transmitting a notify message comprises transmitting a notify message having session initiation protocol fields.

8. The method of claim 7 wherein the tag criterion comprises at least one wildcard.

9. The method of claim 7 wherein the tagging sensor criterion comprises at least one character representing at least one non-wildcard character.

10. The method of claim 9 wherein the at least one wildcard comprises a range designation.

11. A presence server for communicating presence information to a subscriber comprising:

a means for receiving a register message having a presence comprising at least one first portion and at least one second portion;

a means for receiving a subscribe message having at least one criterion;

a means for matching the at least one criterion to the presence; and

a means for transmitting a notify message having the at least one first portion to the subscriber.

12. The presence server of claim 11 wherein the first portion comprises at least one tag portion.

13. The presence server of claim 12 wherein the at least one criterion comprises at least one tag criterion and at least one tagging sensor criterion.

14. The presence server of claim 13 wherein the means for receiving a register message comprises:

receiving the register message at a first domain, the register message originating from a second domain.

15. The presence server of claim 13 wherein the register message comprises at least one session initiation protocol field.

16. The presence server of claim 13 wherein the register message comprises a domain.

17. The presence server of claim 13 wherein the means for transmitting a notify message comprises a means for transmitting a notify message having session initiation protocol fields.

18. The presence server of claim 17 wherein the tag criterion comprises at least one wildcard.

19. The presence server of claim 17 wherein the tagging sensor criterion comprises at least one character representing at least one non-wildcard character.

20. The presence server of claim 19 wherein the at least one wildcard comprises a range designation.

21. A method for reporting location of a tag having a tag identifier near a sensor having a unique identifier among sensors in a first domain comprising:

receiving the tag identifier;

transmitting the tag identifier and the unique identifier to a network node.

22. The method for reporting location of claim 21 wherein the step of transmitting the tag identifier comprises:

transmitting the tag identifier, and the unique identifier to a network node in a second domain.

23. The method for reporting location of claim 22 wherein the step of transmitting the tag identifier further comprises:

transmitting a packet having at least one session initiation protocol field.

24. The method of claim 23 further comprising concatenating the tag identifier with the unique identifier.

25. The method of claim 23 where the step of transmitting the tag further comprises addressing the packet to the subscription network center.

26. The method of claim 23 wherein the message comprises a status.

27. The method of claim 26 wherein the status comprises moving.

28. The method of claim 21 wherein the step of receiving the tag identifier further comprises wirelessly reading the tag.
