Method, telecommunication system and telecommunication handset for wireless communication and telecommunication in a smart home environment

In order to achieve simple, user-friendly "smart home" scenarios in a telecommunications system in the context of the transmission of textual, audio, video and/or control data between a data source and a data sink, a mobile element of the telecommunications system generates control commands and transmits the latter in a target manner in message traffic between the units that form part of the wireless communication or telecommunication process via the air interface. The mobile element is preferably configured as a cordless telephone handset or a mobile telephone. Textual, audio, video and/or control data that has been stored in the data source is detected, issued, released or externally transferred to a data sink or issued to a data source with the aid of the control commands.
