Abstract

At least one network-enabled device, particularly a domestic appliance, is switched from a first network access device, that is connected to a communication network device, to a second network access device, that is to be connected to the communication network device, without manual intervention on the device which sends a message thereto after connection to the first network access device and which has received therefrom a clear address that has been allocated in the communication network device. An individual command signal is emitted by a control device that is connected to the communication network device, placing the respective devices that have sent messages to the first network access device in a state resulting in a new message, whereupon a new message occurs in the second network access device when the first network access device is taken away from the communication network device or disconnected by the respective device, enabling the respective device to receive an allocated clear address in the above mentioned communication network device.

Claims

1-4. -4. (canceled)

5. A method of controlling a switching of a network-enabled device from a first network access device to a second network access device in a communication network configuration, wherein:

the network-enabled device, after connecting to the first network access device, has registered itself from an initial state thereof at the first network access device and has received from the first network access device a unique address in the communication network configuration;

functions of the network access device include converting home appliance-specific protocols or file formats into bus-uniform or standardized protocols or data formats of the bus network and converting bus-uniform or standardized protocols or data formats of the communication network into home appliance-specific protocols or data formats; and

a control device is connected to the communication network configuration;

the method which comprises;

issuing a separate command signal in a course of the switching by the control device, the command signal controlling the respective devices registered at the first network access device to put the respective devices into a state bringing about a new registration through which a new registration procedure is initiated from the respective device;

subsequently, with the first network access device switched off or removed from the communication network configuration, undertaking a new registration of the respective device in the second network access device, and thereby obtaining with the respective device a unique address in the communication network configuration.

6. The method according to claim 5, wherein the network enabled device is a network-enabled home appliance.

7. The method according to claim 5, which comprises, in a communication network configuration with at least two communication networks, issuing the separate command signal from one gateway device or via one of the devices to the one communication network of which the respective devices are connected via a network access device and of which the further communication networks are each connected by way of a gateway device to the said one communication network or to each other.

8. A device for executing the method according to claim 5 for controlling a switch of a network-enabled device from a first network access device to a second network access device in a communication network configuration, wherein:

the network-enabled device, after connecting to the first network access device, has registered itself from an initial state thereof at the first network access device and has received from the first network access device a unique address in the communication network configuration;

functions of the network access device include converting home appliance-specific protocols or file formats into bus-uniform or standardized protocols or data formats of the bus network and converting bus-uniform or standardized protocols or data formats of the communication network into home appliance-specific protocols or data formats; and

a control device connected to the communication network configuration;

said control device issuing a separate command signal in a course of the switch, the command signal controlling the respective devices registered at the first network access device to put the respective devices into a state bringing about a new registration through which a new registration procedure is initiated from the respective device; and

wherein subsequently, with the first network access device switched off or removed from the communication network configuration, a new registration procedure is enabled for execution only with said second network access device.

9. The device according to claim 8, wherein said network enabled device is a network-enabled home appliance.

10. The device according to claim 8, wherein said control device is a gateway device connecting the communication networks of the communication network configuration to each other, or a control and monitoring device connected or connectable to the gateway device.
