Abstract: A method and system of transmitting a message from a transmitting client to a primary receiving client via a proxy server, which is also connected to a secondary receiving client. A message is sent from the transmitting client to the proxy server. The message includes a first header indicative of an address of the primary receiving client and a second header indicative of an address of the secondary receiving client and the primary header being indicative of only a single one of the addresses. The message is then transmitted from the proxy server to the primary receiving client and from the proxy server to the secondary receiving client.

Abstract: A system, apparatus, and method for introducing services into a Push to Talk (PTT) environment. Requests for services are generated and transmitted via requesting PTT clients. The request is received at a PTT server, which forwards the request to a PTT application server recognized by the PTT server as another PTT client. The requested service is performed at the PTT application server, and a result is generated in response. The result is transmitted from the PTT application server to the requesting PTT client by way of the PTT server.

Abstract: A method, apparatus, and system are disclosed for creating a conferencing access logic. The logic is for allowing access to a conference in an internet protocol (IP) network. The invention entails establishing an allow list of allowed users, setting up a default policy applicable to unlisted users, matching listed users with corresponding conference rights, and assigning a uniform resource identifier (URI) to the access logic. The URI is for identifying and editing elements of the access logic, including the allow list, the default policy, and the conference rights.

Abstract: A communications interface between an end-user and an edge node of a communication network for establishing, prior to data transmission, the differentiated service code points supported by the network. The end-user first issues a service request message (42) to an edge node of the communication network. The edge node responds with an acknowledgment message (44) carrying information as to which DSCP's the network is able to support. Finally, the application at the end-user can decide how to mark the relevant packets during data transmission depending on the levels of differentiated service supported by the network.

Abstract: A telecommunications method and system of floor control, for enabling at least one conference participant to access a shared object or resource for purposes of input. A floor control command signal establishes at least one floor control policy, and the floor control command signal includes a floor control language script for automatically determining the access. This access is determined based upon factors such as access requests and prior access history, without need for a floor chair.
