SYSTEM AND METHOD OF MULTI-MEDIA CONFERENCING BETWEEN UNIVERSAL PLUG AND PLAY (UPNP) ENABLED TELEPHONY DEVICES AND WIRELESS AREA NETWORK (WAN) DEVICES

摘要

The present invention provides a system and method of multi-media conferencing between Universal Plug and Play (UPnP) telephony devices and Wide Area Network (WAN) devices. In one embodiment, a method includes initiating a multi-media conferencing session with WAN devices by at least one telephony control point (TCP) in an UPnP telephony based home network via an initiate session request. The method further includes establishing the multi-media conferencing session between the TC and the WAN devices by a telephony server (TS) in the UPnP telephony based home network based on the initiate session request. During the ongoing session, the method further includes receiving a modify session request from the at least one TCP and modifying the session based on the modify session request.
