20090207988 | Method and system for telecommunication sessions using only initial signal messages - A telecommunications system includes a telecommunications network. The system includes n nodes, where n is an integer greater than or equal to 3, in communication with the network. The system includes a host node that creates a session through the network between the n nodes. The system includes an additional node in communication with the network, the host node adding the additional node to the session without any signaling messages being sent from the n nodes. A method for telecommunicating. | 08-20-2009 |
20100002885 | Efficient multiparty key exchange - A system for providing secure communications includes a telecommunications network. The system includes N nodes and a new node in communication with the network to form a session, where N is greater than or equal to three and is an integer. Each node has media streams, and a unique cryptographic media key for each media stream which each node sends to every other node of the session over the telecommunications network. One of the N nodes is a key master which distributes a master key to every other node in the session over the network. Each node encrypts with its own respective media key and the master key each of its media streams. When the new node first joins the session, the new node sends its unique cryptographic media keys for each of its media streams to the N nodes of the session. The key master then generates a new master key with the media keys of the new node and distributes the new master key to the new node and the N nodes using only a single signalling message to each of the N nodes and the new node without any other signalling messages to establish secure communications between the new node and the N nodes in the session. A method for providing secure communications. | 01-07-2010 |
20120086769 | Conference layout control and control protocol - A teleconferencing system-includes a plurality of nodes in communication with each other to form a conference. At least one of the nodes individually controlling, partially, the display layout of each node in the conference. A method for providing a teleconference including forming a conference with a plurality of nodes through a network. At least one of the nodes controls at least partially the display layout of each node in the conference with a specific format unique for each node. A teleconferencing system includes a plurality of nodes in communication with each other through the network to form a conference. Each node communicating only a change to the other nodes when the change occurs. A method for conducting a telecommunications conference between at least three parties includes establishing a conference between the parties and where there is a change to the conference only the change is communicated to the parties. | 04-12-2012 |
