Abstract

A computer-implemented apparatus and method for communicating partial notifications relating to a presentity'"'"'s presence information. The communication may be effected between presence servers and terminals coupled to the presence servers via a network. At least one presentity is identified to which a terminal has requested presence services. A presence document is created, where the presence document includes presence information corresponding to the presentity. The presence information is configured as partial presence information comprising less than a total of the presence information available for the presentity. The presence document having the partial presence information is communicated to the terminal requesting the presence information.

Claims

1. A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

creating a new presence document corresponding to a presentity;

determining partial presence information as a portion of available presence information including new presence information that has changed from a previous presence document; and

creating a namespace extension to an existing published presence specification, wherein the namespace extension includes a version parameter, an action element, and a mode element, wherein the action element indicates an action to be taken at a terminal on a corresponding tuple, and wherein the mode element indicates whether a notification includes the partial presence information or provides a complete presence state;

causing, at least in part, transmission of the new presence document including in part the namespace extension to a terminal requesting the presence information.

2. The non-transitory computer-readable storage medium of claim 1, wherein the new presence document conforms to a Common Profile for Instant Messaging (CPIM) specification using Presence Information Data Format (PIDF), and the namespace extension to the CPIM PIDF presence document is created to facilitate determination of the partial presence information as a portion of the available presence information.

3. The non-transitory computer-readable storage medium of claim 1, wherein the mode element indicates status information for one or more presence document tuples that have experienced a status information change.

4. The non-transitory computer-readable storage medium of claim 1, wherein the version parameter corresponding to a new version of the tuple indicates that the tuple has experienced a status information change.

5. The non-transitory computer-readable storage medium of claim 1, wherein the version parameter of the new presence document is provided as a document version indicator, and the document version is used by the terminal to determine whether new presence information stored at the terminal is synchronized with a presence server.

6. The non-transitory computer-readable storage medium of claim 1, wherein the apparatus is further caused to perform facilitating terminal subscription to the available presence information of at least one presentity.

7. The non-transitory computer-readable storage medium of claim 6, wherein the facilitation of the terminal subscription to the available presence information comprises facilitating at least one of terminal-initiated fetching and terminal-initiated polling for the available presence information of at least one presentity.

8. The non-transitory computer-readable storage medium of claim 7, wherein the facilitation of the terminal subscription to the available presence information of at least one presentity comprises subscribing the terminal to presence information notifications initiated at a presence server.

9. The non-transitory computer-readable storage medium of claim 1, wherein the transmission of the presence document comprises transmitting the presence document in response to at least one of an occurrence of a predetermined event, an occurrence of a predetermined time lapse, and a predetermined time.

10. The non-transitory computer-readable storage medium of claim 1, wherein the determination of partial presence information comprises providing at least one predefined attribute value with the partial presence information.

11. A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

creating a presence document for use by at least one terminal requesting presence information regarding a presentity;

causing, at least in part, transmission of the presence document to the at least one terminal requesting the presence information;

comparing a current version value provided via a tuple to a previous version value stored on the at least one terminal; and

directing the at least one terminal to update presence information associated with the tuple, if the version value provided via the tuple indicates new presence information is available for that tuple,

wherein the creation of the presence document includes creating a namespace extension to an existing presence specification, wherein the namespace extension includes a version parameter, an action element, and a mode element, wherein the action element indicates an action to be taken at a terminal, and wherein the mode element indicates whether a notification includes partial presence information or provides a complete presence state; and

wherein creating the presence document includes creating at least one tuple, the tuple includes a version value indicating a version of the tuple relative to previous versions of the tuple, and associating presence information with the tuple, the presence information includes a subset of a presentity'"'"'s complete set of presence information.

12. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

generate at least one request for new presence information of at least one presentity,

receive a presence document corresponding to the presentity, the presence document having the new presence information that includes partial presence information that has changed from a previous presence document, wherein the new presence document was created using a namespace extension to an existing presence specification, wherein the namespace extension includes a version parameter, an action element, and a mode element, wherein the action element indicates an action to be taken at a terminal, and wherein the mode element indicates whether a notification includes partial presence information or provides a complete presence state; and

cause, at least in part, an update of one or more portions of the presence information identified by the partial presence information.

13. The apparatus as in claim 12, wherein the at least one request is a subscription request to subscribe to the presence information of the at least one presentity.

14. The apparatus as in claim 13, wherein the subscription request comprises a Session Initiation Protocol (SIP) SUBSCRIBE method.

15. The apparatus as in claim 14, wherein the SUBSCRIBE method includes a Uniform Resource Identifier (URI) for the at least one presentity.

16. The apparatus as in claim 12, wherein the apparatus is further caused to receive the partial presence information by fetching the partial presence information.

17. The apparatus as in claim 12, wherein the apparatus is further caused to receive the partial presence information via a partial presence notification identifying the portion of the presence information available for the at least one presentity.

18. The apparatus as in claim 12, wherein the apparatus is further caused to receive the partial presence information in the form of a notification message to provide a watcher application with the partial presence information.

19. The apparatus as in claim 18, wherein the notification message comprises a Session Initiation Protocol (SIP) NOTIFY method.
