Abstract

A presence server transforms a presentities preferences from a device view to a media view by collecting raw preference data from the presentity in a variety of formats and processing the raw preference data to determine a preferred order of media types. The raw preference data includes a preference indication for each media type supported by each device associated with the presentity. The preferred order of media types can be provided to a watcher of the presentity.

Claims

1. A presence system, comprising:

a presence server capable of collecting raw preference data from a presentity in a variety of formats, said raw preference data including a preference indication for each media type supported by each device associated with said presentity;

wherein said presence server is operable to process said raw preference data to determine a preferred order of media types and provide said preferred order of media types to a watcher of said presentity.

2. The presence system of claim 1, wherein said raw preference data includes crisp data indicating a q-value for each device associated with said presentity.

3. The presence system of claim 2, wherein said crisp data further includes a q-value for each media type supported on each device associated with said presentity.

4. The presence system of claim 3, wherein said crisp data further includes a q-value for each media type supported by each application running on each device associated with said presentity.

5. The presence system of claim 4, wherein said presence server is further operable to compute a total q-value for each media type supported on each device from said crisp data.

6. The presence system of claim 5, wherein said presence server is further operable to compute an overall q-value for each media type from said total q-value computed for each device.

7. The presence system of claim 6, wherein said presence server is further operable to determine said preference order of media types from said overall q-value computed for each media type.

8. The presence system of claim 1, wherein said raw preference data includes non-crisp data, and wherein said presence server is further operable to use said non-crisp data to determine a q-value for each media type supported on each device associated with said presentity.

9. The presence system of claim 8, wherein said non-crisp data includes at least one of an order of preference of media types supported on each device associated with said presentity, a fuzzy preference relation of media types supported on each device associated with said presentity, a utility value for each media type supported on each device associated with said presentity and a linguistic ranking of media types supported on each device associated with said presentity.

10. A presence server, comprising:

a data adapter capable of collecting raw preference data from a presentity in a variety of formats, said raw preference data including a preference indication for each media type supported by each device associated with said presentity; and

a controller operable to process said raw preference data to determine a preferred order of media types and provide said preferred order of media types to a watcher of said presentity.

11. The presence server of claim 10, wherein said data adapter includes a crisp data adapter capable of collecting crisp data indicating a q-value for each media type supported by each application running on each device associated with said presentity.

12. The presence server of claim 11, wherein said data adapter further includes a non-crisp data adapter capable of collecting non-crisp data, and wherein said non-crisp data adapter is operable to determine a q-value for at least each media type supported on each device associated with said presentity using said non-crisp data.

13. The presence server of claim 12, wherein said controller is further operable to compute a total q-value for each media type supported on each device from said crisp data and said non-crisp data.

14. The presence system of claim 13, wherein said presence server is further operable to compute an overall q-value for each media type from said total q-value computed for each device.

15. The presence system of claim 14, wherein said presence server is further operable to determine said preference order of media types from said overall q-value computed for each media type.

16. A method for transforming a device view of presentity preferences into a media view, comprising the steps of:

collecting raw preference data from a presentity in a variety of formats, said raw preference data including a preference indication for each media type supported by each device associated with said presentity;

processing said raw preference data to determine a preferred order of media types; and

providing said preferred order of media types to a watcher of said presentity.

17. The method of claim 16, wherein said raw preference data includes at least one of crisp data and non-crisp data, wherein said crisp data indicates a q-value for each media type supported by each application running on each device associated with said presentity, and further comprising the step of:

determining a q-value for at least each media type supported on each device associated with said presentity using said non-crisp data.

18. The method of claim 17, wherein said processing further includes computing a total q-value for each media type supported on each device from said crisp data and said non-crisp data.

19. The method of claim 18, wherein said processing further includes computing an overall q-value for each media type from said total q-value computed for each device.

20. The method of claim 19, wherein said processing further includes determining said preference order of media types from said overall q-value computed for each media type.
