Abstract

A collaboration services suite is adapted to support a plurality of integrated telecommunications services accessed by geographically dispersed team members using a virtual team environment (VTE) client that generates a graphical user interface (GUI) for each of the respective team members. Communications sessions are automatically set up by the collaboration services suite in response to request messages generated by the VTE client when a team member initiates a communications session request using the GUI. Team members require no knowledge of another team member'"'"'s communications device address in order to initiate a communications session. The collaboration services suite includes a VTE server that communicates with the VTE clients, a presence engine that collects and maintains a status of communications devices specified in a current profile of the team member; and, a call server for handling setup and control of a voice component of each communications session completed.

Claims

1. A method of inviting a person to join a communications session initiated using a collaboration services suite accessed from a team member interface of a virtual team environment, comprising steps of:

responding to an action performed by a team member to initiate the invitation from the team member interface, by sending an invitation request message to the collaboration services suite;

analyzing the invitation request message at the collaboration services suite, and sending the invitation from the collaboration services suite to the person, using a preferred, available communications medium selected by the collaboration services suite using dynamic presence and availability information maintained by the collaboration services suite.

2. A method as claimed in claim 1 wherein the action responded to comprises a selection of a communications icon associated with a personal identifier of the person displayed on the team member interface, the selection causing the team member interface to open a communications invitation window.

3. A method as claimed in claim 1 wherein the action responded to comprises a selection of an invitation option from an in-progress communications window.

4. A method as claimed in claim 1 wherein the action responded to comprises a selection of an entry associated with the person from a directory, and a subsequent selection of a communications option associated with the directory.

5. A method as claimed in claim 1 wherein the invitation request message includes an identification of the team member, an identification of the person, and an identification of a communications session type.

6. A method as claimed in claim 5 wherein the identification of the communications session type is one of an identifier of a type of communication, and a communications session identifier that is associated with a communications session that is in progress.

7. A method as claimed in claim 5 wherein the invitation request message further includes at least one of a list of participants and invitees, and any meeting notes input prior to a sending of the invitation.

8. A method as claimed in claim 5 wherein the invitation request message further includes at least one of a topic related to the communications session, and a text message that describes a purpose of the communications session.

9. A method as claimed in claim 5 wherein the communications type is any one of an instant text messaging session, a voice call session and a multimedia session.

11. A method as claimed in claim 10 further comprising, if the person is a team member, a step of examining a current profile associated with the team member to determine a preferred communications medium and using the dynamic presence and availability information maintained by the collaboration services suite in order to determine if the preferred communications medium is available for receiving the invitation.

12. A method as claimed in claim 11 wherein the preferred communications medium for sending the invitation is an invitation message sent to the team member interface.

13. A method as claimed in claim 12 wherein the invitation message opens a communications session invitation window on the team member interface.

14. A method as claimed in claim 13 wherein the communications session invitation window displays a list of participants in the communications session.

15. A method as claimed in claim 14 wherein the communications session invitation window displays a list of invitees the communications session.

16. A method as claimed in claim 14 wherein the communications invitation window further displays a topic of discussion related to the communications session.

17. A method as claimed in claim 16 wherein the communications invitation further displays meeting notes entered by the participants in the communications session.

18. A method as claimed in claim 12 wherein the preferred medium for sending the invitation is a text device, if the team member interface is not available.

19. A method as claimed in claim 18 wherein the text device displays a communications session type in the invitation window and a personal identifier associated with a team member that sent the invitation.

20. A method as claimed in claim 18 wherein the preferred device for sending the invitation is a voice communications device, if a text device is not available.

21. A method as claimed in claim 20 wherein an interactive voice response unit (IVR) plays an announcement to the person, to invite the person to join the communications session when the person answers the voice communications device.

22. A method as claimed in claim 21 wherein the IVR comprises part of a functionality of a conference bridge.

23. A method as claimed in claim 21 wherein the IVR also plays a list of the persons attending the communications session and a topic of discussion.

24. A method as claimed in claim 1 wherein sending the invitation comprises a step of formulating an invitation message and sending the invitation message to the team member interface, which displays a communications invitation window to the person.

25. A method as claimed in claim 24 wherein the invitation window displays a topic of discussion of the communications session.

26. A method as claimed in claim 25 wherein the invitation window further displays meeting notes generated during the communications session prior to the sending of the invitation request message.

27. A method as claimed in claim 24 wherein the invitation window displays options to join the communications session, decline the communications session invitation, or indicate a desire to join the communications session at a later time.

28. A method as claimed in claim 27 wherein the invitation window permits a reply message to be returned with any one of the options selected for a response.

29. A method as claimed in claim 27 wherein if the person elects to join the communications session, a message is sent by the team member interface to the collaboration services suite, and the collaboration services suite joins the person to the communications session.

30. A method as claimed in claim 29 wherein the collaboration services suite further advises each team member of the change in status of the person when the person is joined to the communications session.

31. A method as claimed in claim 28 wherein the reply message is display on the team member interface of all team members participating in the communications session.

32. A method as claimed in claim 29 wherein if the communications session is an instant messaging session, a connection manager is instructed to copy all text messages to the person, and to copy all text messages from the person to other members of the communications session.

33. A method as claimed in claim 29 wherein if the communications session is a voice conference session, a virtual switching point is instructed to join the person'"'"'s preferred voice communications device to the voice conference.

34. A method as claimed in claim 33 wherein the preferred voice communications device is determined using the persons profile, if the person is a team member, and a number supplied in the invitation request message if the person is not a team member.

35. A method as claimed in claim 34 wherein joining the preferred voice communications device to the voice communications session comprises steps of:
