CLAIMS

What is claimed is:

1. A method comprising:

receiving, by a first user equipment (UE) during a call session between the first UE and a second UE that is being managed by a call application server, a user input requesting that the call session be upgraded to a meeting session;

sending, by the first UE, a meeting request to a conference application server; receiving, by the first UE, a meeting confirmation from the conference application server, wherein the meeting confirmation indicates that the conference application server has set up the meeting session and includes meeting information associated with the meeting session;

joining, by the first UE, the meeting session based on meeting information in the meeting confirmation;

sending, by the first UE, a meeting referral to the conference application server requesting that the second UE be invited to the meeting session; and

ending, by the first UE, a leg of the call session after the second UE has joined the meeting session.

2. The method of claim 1, further comprising:

displaying, by the first UE, a call mode user interface during the call session; and

switching, by the first UE, to displaying a meeting mode user interface upon joining the meeting session.

3. The method of claim 1, wherein the meeting request, the meeting

confirmation, and the meeting referral are exchanged between the first UE and the conference application server via the call application server.

4. The method of claim 1, wherein a communication application run at, or accessed by, the first UE engages in the call session, receives the user input, sends the meeting request, receives the meeting confirmation, joins the meeting session, and sends the meeting referral.

5. The method of claim 1, wherein:

the user input is received by the first UE during the call session with the second UE and also during a second call session with a third UE, and

the meeting referral requests that both the second UE and the third UE be invited to the meeting session.

6. The method of claim 5, wherein at least one of the call session and the second call session is on hold when the user input is received.

7. The method of claim 1, wherein the meeting session provides one or more meeting functions that are unavailable to the first UE and the second UE during the call session.

8. The method of claim 7, wherein the meeting functions include at least one of a whiteboard function and a screen sharing function.

9. The method of claim 1, wherein the meeting information includes at least one of link information and a meeting identifier that the first UE can use to join the meeting session.

10. A method comprising:

receiving, by a first user equipment (UE) during a call session between the first UE and a second UE that is being managed by a call application server, a meeting invitation to a meeting session managed by a conference application server, wherein the second UE requested an upgrade from the call session to the meeting session;

sending, by the first UE, a meeting acceptance to the conference application server;

joining, by the first UE, the meeting session based on meeting information in the meeting invitation;

switching, by the first UE, from displaying a call mode user interface displayed during the call session to displaying a meeting mode user interface upon joining the meeting session; and

ending, by the first UE, a leg of the call session after joining the meeting session.

11. The method of claim 10, wherein the meeting invitation and the meeting acceptance are exchanged between the first UE and the conference application server via the call application server.

12. The method of claim 10, wherein a communication application run at, or accessed by, the first UE engages in the call session, receives the meeting invitation, sends the meeting acceptance, joins the meeting session, and switches to displaying the meeting mode user interface.

13. The method of claim 10, wherein the call session is on hold when the first UE receives the meeting invitation.

14. The method of claim 10, wherein the meeting session provides one or more meeting functions that are unavailable to the first UE and the second UE during the call session.

15. The method of claim 10, wherein the meeting information includes at least one of link information and a meeting identifier that the first UE can use to join the meeting session.

16. A call application server comprising:

one or more processors; and

memory storing computer-executable instructions that, when executed by the one or more processors, cause the call application server to perform operations comprising:

managing call session between a first user equipment (UE) and a second UE;

routing one or more meeting setup messages between the first UE and a conference application server that is configured to set up a meeting session for the first UE and the second UE;

routing one or more meeting invitation messages between the conference application server and the second UE;

determining that both the first UE and the second UE have joined the meeting session based on at least some of the one or more meeting setup messages and the one or more meeting invitation messages; and

sending end call instructions to the first UE and the second UE in response to determining that both the first UE and the second UE have joined the meeting session, wherein the end call instructions instruct the first UE and the second UE to end the call session.

17. The call application server of claim 16, wherein the operation of routing the one or more meeting setup messages comprises:

receiving a meeting request from the first UE during the call session and forwarding the meeting request to the conference application server, wherein the meeting request is a request to upgrade the call session to the meeting session;

receiving a meeting confirmation from the conference application server and forwarding the meeting confirmation to the first UE; and

receiving a meeting referral from the first UE requesting that the second UE be invited to the meeting session and forwarding the meeting referral to the conference application server.

18. The call application server of claim 16, wherein the operation of routing the one or more meeting invitation messages comprises:

receiving a meeting invitation from the conference application server and forwarding the meeting invitation to the second UE; and

receiving a meeting acceptance from the second UE and forwarding the meeting acceptance to the conference application server.

19. The call application server of claim 16, wherein the call application server communicates with a communication application associated with the first UE when managing the call session, routing the one or more meeting setup messages, and sending the end call instructions.

20. The call application server of claim 16, wherein the call application server routes the one or more meeting setup messages during the call session.
