Registration based addressing over multiple networks with digital audio communication
First Claim
1. A method of communication between a plurality of users, comprising:
- allowing at least first and second users to establish communication over at least two separate communications networks by first and second communication devices, associated respectively with the first and second users, registering with at least one communications network;
maintaining at least one service record for at least the first and second users, each service record including at least the second user'"'"'s location information;
allowing the first user to request communication with the second user;
causing retrieval of the location information of the second user in response to the request by the first user;
initiating a communication, including at least audio, between the first and second users by using at least one of the communications networks and the retrieved location information; and
wherein the audio communication is transmitted digitally over at least one network.

Abstract
A multimedia collaboration system that integrates separate real-time and asynchronous networks—the former for real-time audio and video, and the latter for control signals and textual, graphical and other data—in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mixing technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.

21. A system for communicating between a plurality of users, comprising:
-
(a) at least one communication device associated with each user;
(b) at least one communications network over which at least first and second users can establish communication by at least one communication device registering with at least one communication network; and
(c) at least one service record, for at least the second user, including at least the second user'"'"'s location information;
wherein the system is configured to;
allow the first user to request communication with the second user;
retrieve the location information of the second user in response to the request by the first user; and
initiate a communication, including at least audio communication, between the first and second users by using at least one of the communications networks and the retrieved location information; and
creating at least a first and second call handle, respectively associated with the first and second users'"'"' communication devices, each call handle defining at least a call state for its associated device. - View Dependent Claims (22, 23, 24, 25, 26, 28, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
