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

A telecommunication system for wireless communication and telecommunication in a smart home environment comprising:

• a base station for conducting telephone calls and sending/receiving at least one of text, audio, video and control data, which can be connected to:
• at least one of a circuit-switched network and a packet-switched network with an EXTERNAL data source/data sink assigned to said network for at least one of text, audio, video and control data;
• and
• at least one mobile element for at least one of conducting telephone calls and sending/receiving at least one of text, audio, video and control data via at least one air interface or via at least one air interface and a line interface;
• wherein a first mobile element being configured to send/receive at least one of text, audio, video and control data, wherein the first mobile element and the base station being assigned respectively to an INTERNAL data source/data sink, to receive the at least one of text, audio, video and control data intended for the first INTERNAL data source/data sink and to send the at least one of text, audio, video and control data originating from the first INTERNAL data source/data sink;
• wherein a second mobile element is configured to conduct EXTERNAL telephone calls or to EXTERNAL send/receive at least one of text, audio, video and control data via the base station and, if there is more than one second mobile element, also to conduct INTERNAL telephone calls or to send/receive internally at least one of text, audio, video and control data between the second mobile elements;
• wherein the second mobile element comprises:
• a central control unit connected to the air interface to control the operation and function processes in the second mobile element,
• a storage unit assigned to the central control unit,
• means to connect to the central control unit for inputting at least one of text, audio, video and control data, and
• means for outputting at least one of text, audio, video and control data, which form a function unit, which is configured such that control commands are generated and transmitted via the air interface;
• wherein said control commands are configured to access at least one of text, audio, video and control data terminated in the base station, the first mobile element, the second mobile element, and the INTERNAL data source/sink;
• and
• wherein the data being sent from the at least one of the base station, the first mobile element, the second mobile element, and the INTERNAL data source/sink in which the data terminated, directly or indirectly to at least one of the INTERNAL data source/data sink or a further INTERNAL data source/data sink, the second mobile element or a further second mobile element, and the EXTERNAL data source/data sink to be output, released or transferred out.
