Abstract

A method for facilitating communication with a user. The method comprises the steps of: receiving contact information for the user, from a presence service; checking to determine if a particular communication service is supported by the user; checking to determine if the contact address of the user is accessible; launching at least one of an appropriate helper application and objects; and initiating communication with the user through the particular communication service.

Claims

1. A method for facilitating communication with a user, the method comprising the steps of:

receiving contact information for said user, from a presence service, said contact information comprising a contact address of the user;

checking to determine if a particular communication service is supported by said user said particular communication service associated with said contact address;

checking to determine if the contact address of the user is accessible;

launching at least one of a helper application that assists with said particular communication service and an object that supports said particular communication service, in response to said contact address of the user being accessible; and

initiating communication with the user through the particular communication service.

2. A method as claimed in claim 1, wherein said step of checking to determine if a particular communication service is supported comprises checking a service look-up table.

3. A method as claimed in claim 2, wherein said step of checking said service look-up table includes determining if domain information in a service url of the user is accessible.

4. A method as claimed in claim 2, wherein said step of checking to determine if the contact address of the user is accessible is based on an address-family of the user.

5. A method as claimed in claim 2 further comprising the step of receiving availability information of the user from a presence service, prior to the step of receiving contact information.

6. A method as claimed in claim 2 further comprising the step of projecting availability information to the presence service, prior to the step of receiving availability information of the user.

7. A method as claimed in claim 3, wherein said step of checking to determine if the contact address of the user is accessible is based on an address-family of the user.

8. A method as claimed in claim 3 further comprising the step of receiving availability information of the user from a presence service, prior to the step of receiving contact information.

9. A method as claimed in claim 3 further comprising the step of projecting availability information to the presence service, prior to the step of receiving availability information of the user.

10. A method as claimed in claim 1, wherein said step of checking to determine if the contact address of the user is accessible is based on an address-family of the user.

11. A method as claimed in claim 10 further comprising the step of receiving availability information of the user from a presence service, prior to the step of receiving contact information.

12. A method as claimed in claim 10 further comprising the step of projecting availability information to the presence service, prior to the step of receiving availability information of the user.

13. A method as claimed in claim 1 further comprising the step of receiving availability information of the user from said presence service, prior to the step of receiving contact information.

14. A method as claimed in claim 13 further comprising the step of projecting availability information to the presence service, prior to the step of receiving availability information of the user.

15. A method as claimed in claim 1 further comprising the step of projecting availability information to the presence service, prior to the step of receiving availability information of the user.

16. A method for facilitating communication with a presentity, comprising the steps of:

projecting a subscription request to a presence service for determining the availability of the presentity;

receiving a notification message from the presence service in response to said subscription request, said notification message comprising a role tags for identifying a role that the presentity is in and a key tag for identifying the availability of the presentity for the subscription request;

receiving a notification of availability of the presentity if said role tag is indicative that the presentity is in a role where notifications of availability may be received, and said key tag is indicative that the presentity is available for the subscription request; and

,

responsive to said notification of availability being indicative of the presentity being available,

checking to determine if a particular communication service is supported by the presentity;

checking network accessibility of the presentity;

launching at least one of a helper application that assists with said particular communication service and an object that supports said particular communication service, in response to said network accessibility of the presentity being accessible; and

initiating communication with the presentity through the particular communication service.

17. A method as claimed in claim 16, wherein said step of checking to determine if a particular communication service is supported comprises checking a service look-up table.

18. A method as claimed in claim 17, wherein said step of checking said service look-up table includes determining if domain information of the presentity is accessible.

19. A method as claimed in claim 17, wherein the step of checking network accessibility of the presentity is based on an address-family of the user.

20. A method as claimed in claim 17 further comprising the step of projecting availability information to the presence service, prior to the step of projecting a subscription request.

21. A method as claimed in claim 18, wherein the step of checking network accessibility of the presentity is based on an address-family of the user.

22. A method as claimed in claim 18 further comprising the step of projecting availability information to the presence service, prior to the step of projecting a subscription request.

23. A method as claimed in claim 16, wherein the step of checking to determine if the contact address of the presentity is accessible is based on an address-family of the user.

24. A method as claimed in claim 23 further comprising the step of projecting availability information to the presence service, prior to the step of projecting a subscription request.

25. A method as claimed in claim 16 further comprising the step of projecting availability information to the presence service, prior to the step of projecting a subscription request.

26. A system for facilitating communication with a presentity, comprising:

a presentity presence client;

a watcher presence client for projecting a subscription request;

a presence server connected to the presentity presence client and the watcher presence client, said presence server for receiving the subscription request and for replying to said watcher presence client to identify the availability of the presentity for the subscription request; and

a communication service separate from said presence server and connected to said watcher presence client and said presentity presence client,

wherein said watcher presence client is operable to launch at least one of an helper application that assists with said particular communication service and an object that supports said particular communication service, said watcher presence client further operable to initiate communication with the presentity through the particular communication service.

27. A system for initiating communication as claimed in claim 26 wherein said presentity comprises a presentity resource.

28. A system for initiating communication as claimed in claim 26, wherein said presence server comprises a directory service for storing a data record in association with a plurality of users.

29. A system for initiating communication as claimed in claim 28, wherein said presence server further comprises a user agent for maintaining information about the availability of the presentity, said presence server enabled to determine if the presentity is available.
