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 multimedia conferencing system and method between Universal Plug and Play (UPnP) telephony devices and wide area network (WAN) devices. According to one embodiment, a method includes initiating a multimedia conference session with WAN devices in a UPnP telephony-based home network via at least one Telephony Control Point (TCP) session request. The session request includes session information, media capabilities of a Telephony Client (TC) device associated with the at least one TCP, a list of WAN devices or a conference group identifier associated with one or more WAN devices, . The method further includes establishing a multimedia conference session between the TC and the WAN devices in the UPnP telephony-based home network based on the session request, by a telephony server (TS).
