Abstract

A system and method of conference messaging between Universal Plug and Play (UPnP) telephony devices and Wide Area Network (WAN) devices is where a conference messaging session with WAN devices is initiated by at least one Telephony Control Point (TCP) via a session request which includes session information, media capabilities of at least one TCP, a list of WAN devices, and a subject of the conference messaging session. The conference messaging session is then established between the at least one TCP and the WAN devices by a Telephony Server (TS) in an UPnP telephony based home network based on the session request.

First claim

What is claimed is:

1. A method for performing, by a Telephony Server (TS) in a first network, conference messaging between at least one Telephony Control Point (TCP) in the first network and a plurality of Wide Area Network (WAN) devices connected to a second network, comprising:
receiving a session request associated with a conference messaging session with the plurality of WAN devices from at least one TCP in the first network, wherein the session request includes session information, media capabilities of the at least one TCP, a list of the plurality of WAN devices, and a subject of the conference messaging session;
establishing the conference messaging session between the at least one TCP and the plurality of WAN devices based on the session request,
wherein establishing the conference messaging session comprises:
generating a conference initiation request associated with the conference messaging session, wherein the conference initiation request includes a session identifier, the media capabilities of the at least one TCP, and the subject of the conference messaging session, and
transmitting the conference initiate request to each of the plurality of WAN devices connected to the second network listed in the session request,
receiving a modify session request from the at least one TCP in the conference messaging session while the conference messaging session is ongoing, wherein the modify session request includes the subject of the conference messaging session, the media capabilities of the at least one TCP, and list information of at least one WAN device connected to the second network to be added into or removed from the conference messaging session; and
modifying the ongoing conference messaging session by adding or removing the at least one WAN device according to the list information of at least one WAN device,
wherein the method further comprises:
receiving a leave session request from the at least one TCP in the conference messaging session while the conference messaging session is ongoing;
retrieving the session identifier from the leave session request, wherein the leave session request is used to identify whether to leave the ongoing conference messaging session without termination;
marking an ongoing conference messaging session status as parked; and
notifying associated one or more TCPs and the plurality of WAN devices of the status of the ongoing conference messaging session, each of the associated one or more TCPs being presently or previously on the ongoing conference messaging session,
wherein, while the conference messaging session is ongoing, a dynamic session information associated with the conference messaging session is provided to the at least one TCP, wherein the dynamic session information includes user leaving session information, user joining session information, or any changes in the subject of the conference messaging session, and
wherein the first network is a Universal Plug and Play (UPnP) telephony based home network, and the second network is a WAN.

2. The method of claim 1 , wherein establishing the conference messaging session between the at least one TCP and the plurality of WAN devices comprises:
initiating the conference messaging session with the plurality of WAN devices based on the session request; and
enabling the conference messaging between the at least one TCP and one or more WAN devices from among the plurality of WAN devices based on the media capabilities of the at least one TCP.

3. The method of claim 2 , wherein establishing the conference messaging session between the at least one TCP and the plurality of WAN devices based on the session request further comprises:
retrieving the list of the plurality of WAN devices, the media capabilities of the at least one TCP, and the session information from the session request;
determining whether the session request is associated with the conference messaging session based on the session information; and
if the session request is associated with the conference messaging session, forwarding the conference initiation request to each of the plurality of WAN devices.

4. The method of claim 3 , wherein forwarding the conference initiation request to each of the plurality of WAN devices comprises:
generating the conference initiation request for establishing the conference messaging session between the at least one TCP and the plurality of WAN devices, wherein the conference initiation request includes the session identifier, media capabilities, and a session subject; and
sending the conference initiation request to each of the plurality of WAN devices.

5. The method of claim 4 , wherein establishing the conference messaging session between the at least one TCP and the plurality of WAN devices based on the session request further comprises:
receiving one or more confirmation messages from the one or more WAN devices in response to the conference initiation request, each of the one or more confirmation messages indicating successful initiation of the conference messaging session; and
processing and forwarding the one or more confirmation messages to the at least one TCP.

6. The method of claim 2 , wherein enabling the conference messaging between the at least one TCP and the one or more WAN devices from among the plurality of WAN devices comprises:
enabling exchange of a plurality of instant messages between the at least one TCP and the one or more WAN devices during the conference messaging session based on the media capabilities of the at least one TCP.

7. The method of claim 2 , wherein enabling the conference messaging between the at least one TCP and the one or more WAN devices further comprises:
receiving one or more instant messages from the one or more WAN devices during the conference messaging session;
processing the one or more instant messages such that the one or more instant messages are displayed in a compatible format on a display of the at least one TCP based on the media capabilities of the at least one TCP; and
forwarding the processed one or more instant messages to the at least one TCP.

8. The method of claim 1 , wherein modifying the ongoing conference messaging session further comprises:
retrieving information from the modify session request, wherein the modify session request further includes the session identifier;
transmitting the information retrieved from the modify session request to the plurality of WAN devices;
and
notifying one or more associated TCPs and other active WAN devices connected to the second network of the conference messaging session regarding the addition and removal of the at least one WAN device, each of the associated one or more TCPs being presently or previously in the ongoing conference messaging session.

9. The method of claim 1 , further comprising:
receiving a resume session request from the at least one TCP; and
resuming the ongoing conference messaging session with the plurality of WAN devices based on the resume session request received from the at least one TCP, wherein the status of session is changed to running upon resuming the ongoing conference messaging session.

10. The method of claim 1 , further comprising:
receiving a join session request from the at least one TCP;
retrieving the session identifier from the join session request;
determining whether the retrieved session identifier matches a session identifier in a session identifier list; and
if the retrieved session identifier matches the session identifier of the session identifier list, allowing the at least one TCP to join the conference messaging session based on the join session request.

11. The method of claim 1 , further comprising:
