Method for changing between a packet-oriented PTT session and a circuit-oriented telephone connection between at least two radio communication appliances, associated radio communication appliance, network component and radio communication system

摘要

To change between a packet-oriented PTT session (PC) and a circuit-oriented telephone connection (TC) as selectable communication connections between at least one first connected radio communication appliance (UE1) and at least one second connected radio communication appliance (UE2) in a radio communication system (FC), a first of these two communication connections (PC) is selected and set up by at least one connected radio communication appliance (UE1) and/or by at least one control unit (PTTS1) in the radio network in the radio communication system (FC). A change is made from this first communication connection (PC), which has been set up, to the second communication connection (TC) under the control of a radio communication appliance (UE1) which is connected to the first communication connection (PC) and/or under the control of that control unit (PTTS1) in the radio network in the radio communication system (FC) which is connected to the first communication connection (PC) by activating the second communication connection (TC) while the first communication connection (PC) still exists.
