发明名称 Peer-to-peer broadcasting in a VoIP system
摘要 A method and system provides the ability to use VoIP devices to generate and/or propagate a broadcast message to other devices. A device transmits a broadcast message to a recipient device over a peer-to-peer communication channel. Such a device can be an originator or a propagator designated by a third party. Upon receipt of a request to broadcast a message, or upon detecting any triggering event to broadcast, the device processes the request or the triggering event to compose content of the message. Subsequently, a group of recipient devices are identified and located. The device may transmit the broadcast message over existing communications channels without disturbing a conversation with the recipient device. Further, a peer-to-peer communication channel may be established to transmit the broadcast message. Alternatively, the device may request the recipient device to broadcast the message to devices outside of its current peer-to-peer communication connections.
