Abstract:
1. A method of providing a Push-to-Talk service within one or more telecommunication networks, wherein the method comprises the steps of: requesting one or more concurrent PTT connections between subscribers of the PTT service; setting up a virtual connection per PTT connection by means of a gateway-server providing the PTT service within a circuit-switched telecommunication network, whereby each virtual connection provides information about the terminals participating in the PTT connection, the service type to reach each terminal, and the connection status of each terminal; generating media streams by a terminal of one of the subscribers of the PTT connection and sending the media streams to the gateway-server; determining the virtual connection corresponding to the received media streams by the gateway-server; sending out the media streams to one or more of the other terminals participating in the PTT connection according to the determined virtual connection; and monitoring a telecommunication connection of one of the terminals participating in the PTT connection for an incoming call and indicating the incoming call to the terminal; transmitting a control command to the PTT gateway-server; interrupting the media streams from/to the terminal upon receiving the control command by the PTT gateway-server; putting through the incoming call to the terminal; and resuming the media streams from/to the terminal upon completion of the call.
