Abstract

A system and method is provided for converting RFID tag information into presence documents and, in particular, a system, topologies and a method is provided for leveraging session initiation protocol (SIP) to integrate RFID tag information into presence documents. The method is implemented in a computing environment, which includes receiving RFID information from a RFID gateway and converting the RFID information into a SIP message. The SIP message is published to a presence server.

Claims

1. A method implemented in a computing environment, comprising:

receiving RFID information from a RFID gateway;

converting the RFID information into a SIP message; and

publishing the SIP message to a presence server.

2. The method of claim 1, wherein the RFID information contains payload information which is provided in the SIP message.

3. The method of claim 1, further comprising obtaining location information from a location platform and placing the location information into a presence document with the RFID information to create a rich content presence document.

4. The method of claim 1, further comprising sending the SIP message to a telecommunications network.

5. The method of claim 1, further comprising filling required fields in the SIP message prior to publishing using a JavaScript Object Notation (JSON) format.

6. The method of claim 1, further comprising looking up profile information to determine how to process an event associated with the RFID information prior to publishing the SIP message.

7. The method of claim 1, further comprising updating a repository with a subscriber service profile.

8. The method of claim 7, wherein the updating includes an RFID SIP gateway receiving profile updates from a subscriber profile repository.

9. The method of claim 8, wherein the RFID SIP Gateway registers with a SIP registrar in a telecommunications network.

10. The method of claim 1, wherein:

the SIP message contains “

to”

, “

from”

, “

Subject”

, “

CALL-ID”

, “

contact”

, “

content type” and

“

content length”

fields;

the “

from”

, “

CALL-ID”

, “

contact”

, “

content-type” and

“

content length”

fields are generated by the presence server; and

the “

subject” and

“

to”

fields are population by another device.

11. The method of claim 1, wherein payload information is embedded into the RFID information.

12. The method of claim 1, wherein the steps are provided on a computing infrastructure in the computing environment which is at least one of maintained, deployed, created and supported by a service provider.

13. The method of claim 1, wherein the steps are provided on a software component, a hardware component or a combination of the software component and the hardware component.

14. The method of claim 1, further comprising charging a registrant for a notification of the SIP message.

15. A computer program product comprising a computer usable storage medium having readable program code tangibly embodied in the storage medium, the computer program product comprising:

first program instructions to receive RFID information;

second program instructions to convert the RFID information to a SIP message; and

third program instructions to send the SIP message to a presence server for publishing as a presence document.

16. The computer program product of claim 15, further comprising fourth program instructions to notify third parties of the presence document.

17. The computer program product of claim 15, wherein:

the SIP message contains “

to”

, “

from”

, “

Subject”

, “

CALL-ID”

, “

contact”

, “

content type” and

“

content length”

fields;

the “

from”

, “

CALL-ID”

, “

contact”

, “

content-type” and

“

content length”

fields are generated by the presence server; and

the “

subject” and

“

to”

fields are population by another device.

18. The computer program product of claim 15, further comprising fourth program instructions to provide payload information into the SIP message.

19. The computer program product of claim 15, wherein the RFID information contains payload information provided in the SIP message.

20. The computer program product of claim 15, wherein the computer program product is at least one of maintained, deployed, created and supported by a service provider.

21. The computer program product of claim 15, further comprising fourth program instructions to charge the user for notification of the presence documents.

22. The computer program product of claim 15, further comprising fourth program instructions to obtain location information from a location platform and update the presence document with the location information to create a rich content presence document having the RFID information.

23. The computer program product of claim 15, further comprising fourth program instructions to register users to receive the presence document.

24. A system for provided for converting RFID signals to SIP messages, comprising a gateway implemented on a computer infrastructure operable to convert RFID information into SIP based messaging for publication by a presence server.

25. The system of claim 24, further comprising the gateway and the presence server in an enterprise domain.
