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
First Claim
1. A method for changing between a packet-oriented PTT session and a circuit-oriented telephone connection as two selectable communication connections between at least one first connected radio communication appliance and at least one second connected radio communication appliance in a radio communication system, the method comprising:
- selecting and setting up a first of the two communication connections by at least one of the at least one connected radio communication appliance and at least one control unit in a radio network in the radio communication system; and
changing from the first communication connection, which has already been set up, to a second of the two communication connections under control of at least one of the radio communication appliance which is connected to the first communication connection and a first control unit in the radio network in the radio communication system which is connected to the first communication connection by activating the second communication connection while the first communication connection still exists.

Abstract
Provided are a method for changing between a packet-oriented PTT session and a circuit-oriented telephone connection between at least two radio communication appliances, an associated radio communication appliance, a network component and a radio communication system. To change between a packet-oriented PTT session and a circuit-oriented telephone connection as selectable communication connections between at least one first connected radio communication appliance and at least one second connected radio communication appliance in a radio communication system, a first of these two communication connections is selected and set up by at least one connected radio communication appliance and/or by at least one control unit in the radio network in the radio communication system. A change is made from this first communication connection, which has been set up, to the second communication connection under the control of a radio communication appliance which is connected to the first communication connection and/or under the control of that control unit in the radio network in the radio communication system which is connected to the first communication connection by activating the second communication connection while the first communication connection still exists.

12. A radio communication appliance for use in a method for changing between a packet-oriented PTT session and a circuit-oriented telephone connection as two selectable communication connections between the radio communication appliance and at least one further radio communication appliance in a radio communication system, comprising a control unit wherein a first of the two communication connections is selected and set up by the control unit, and a change is made from the first communication connection, which has already been set up, to a second of the two communication connections under control of the control unit which is connected to the first communication connection by activating the second communication connection while the first communication connection still exists.

14. A radio communication system having a first group of network components for selecting and providing a packet-oriented PTT session and a second group of network components for selecting and providing a circuit-oriented telephone connection as two selectable communication connections between at least one first connected radio communication appliance and at least one second connected radio communication appliance in the radio communication system, comprising control units in each of the first and second groups of network components wherein a first of the two communication connections is selected and set up by one of the control units in a radio network in the radio communication system, and a change is made from the first communication connection, which has already been set up, to a second of the two communication connections under control of the control unit in the radio network in the radio communication system which is connected to the first communication connection by activating the second communication connection while the first communication connection still exists.
