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 switching between (a) a packet-oriented PTT communication connection between a first radio communication device and a second radio communication device and (b) a circuit-oriented telephone connection between the first and second radio communication devices, comprising:
- establishing a communication session between the first and second radio communication via a first communication connection comprising one of (a) the packet-oriented PTT communication connection between the first and second radio communication devices and (b) the circuit-oriented telephone connection between the first and second radio communication devices,during the communication session between the first and second radio communication devices, in response to a change from a first communication situation suitable for the first communication connection to a second communication situation suitable for a second, different communication connection, the first radio communication device initiating a switch from the first communication connection to the second communication connection, the second communication connection comprising the other one of (a) the packet-oriented PTT communication connection between the first and second radio communication devices and (b) the circuit-oriented telephone connection between the first and second radio communication devices, andafter the switch, continuing the communication session between the first and second radio communication devices via the second communication connection,wherein the switch from the first communication connection to the second communication connection comprises activating the second communication connection while the first communication connection still exists.

Abstract
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.

14. A radio communication system having a first group of network components for selecting and providing a packet-oriented PTT communication connection between a first radio communication device and a second radio communication device and also having a second group of network components for selecting and providing a circuit-oriented telephone connection between the first and second radio communication devices the two groups of network components comprising control systems configured to cooperate to switch between (a) the packet-oriented PTT communication connection between the first and second radio communication devices and (b) the circuit-oriented telephone connection between the first and second radio communication devices by:
-
establishing a communication session between the first and second radio communication via a first communication connection comprising one of (a) the packet-oriented PTT communication connection between the first and second radio communication devices and (b) the circuit-oriented telephone connection between the first and second radio communication devices, during the communication session between the first and second radio communication devices, in response to a change from a first communication situation suitable for the first communication connection to a second communication situation suitable for a second, different communication connection, the first radio communication device initiating a switch from the first communication connection to the second communication connection, the second communication connection comprising the other one of (a) the packet-oriented PTT communication connection between the first and second radio communication devices and (b) the circuit-oriented telephone connection between the first and second radio communication devices, and after the switch, continuing the communication session between the first and second radio communication devices via the second communication connection, wherein the switch from the first communication connection to the second communication connection comprises activating the second communication connection while the first communication connection still exists.
