The invention relates to the field of home networks, in particular to the connection of two home networks of different types via a gateway. The network appliances in the network of the first type are also intended to be able to control the network appliances in the network of the second type, and vice versa. One problem that occurs when carrying out conversion processes on control messages is that an input parameter which is known in the network of the first type can be changed as required and can also be signaled further within this network, but the associated correspondence in the network of the second type is permanently set, and accordingly cannot be changed. The invention provides a way in which an input parameter such as this can nevertheless be likewise updated in the network of the second type. For this purpose, the network station which relates to the input parameter is first of all logged-off in the network of the second type. The changed input parameter is then converted to the information element in the network of the second type. The network station which relates to the input parameter is then logged on again in the network of the second type. This results in the network stations in the network of the second type being able to newly read the appliance description for the network station which relates to the input parameter. This then also results in the input parameter being updated in the network of the second type.
