To improve the operating convenience&#x2014;e.g. versatile, universal application and use&#x2014;and location-independence (mobility) of the telecommunication of useful data, particularly packet data and/or voice data, using communication devices, a data adapter (DADA) is allocated both a fixed-part-specific air interface architecture (D&#xdc;M, STM, PKM) for implementing the prescribed air interface protocol, and the air interface architectures associated with the data adapter (DADA) are activated according to the application instance, i.e., which scenario is to be produced for the telecommunication of useful data and, in particular, which communication device (KEKE) is connected to the data adapter (DADA).

Data adapter or communication devices for the telecommunication of useful data, particularly of packet data and/or voice data

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.

In order to qualitatively improve roaming of mobile parts (MT, RPP, DIPS) in at least partially asynchronous, wireless telecommunication networks (TKN) with telecommunication systems (TKS. . . TKSn) having a plurality of base stations (BS, RFP, DIFS) arranged in radio cells (FZ), first base stations (BSRFPDIFS) which are respectively neighbored by at least one asynchronous second base station (BSRFPDIFS) send information to first mobile parts (MTRPPDIPSI) connectible by telecommunication to the first base stations (BSRFPDIFS), said information indicating that the respective, first base station (BSRFPDIFS) sending the information is surrounded by at least one second base station (BSRFPDIFS).

In the case a mobile telecommunications terminal which can be activated at different base stations (a, b, c, d) it is possible to store in a numbers memory () with respect to a call number (column) information (column) which indicates in connection with which of the base stations the call number can be dialed, and display means display only those names among the ones assigned to the call numbers which can be dialed in connection with a designated base station. This base station can be designated manually or automatically by a data exchange with the base station concerned.

Mobile telecommunications terminal

A method for controlling data transmission in a cordless V.24 data transmission system operated between a data terminal and data communication equipment. The method controls data communication equipment for the purpose of data communication with a first data transmission device connected to the data terminal equipment via a V.24 cable and with a second data transmission device connected to the data communication equipment via a V.24 cable. The first and second data transmission devices can be connected via an air interface by wireless telecommunication. Activating, reactivating and deactivating of an auto-bauding function is reliably performed in such a manner that there is no risk that user data transmission is corrupted until it is deactivated. A state machine contained in the first data transmission device tracks the states of the data communication equipment and acts on the state of the auto-bauding function in the first data transmission device. In the alternative, a state machine contained in the second data transmission device tracks the states of the data communication equipment and acts on the state of the auto-bauding function in the first data transmission device.

Method for controlling data transmission in a wireless V.24 data transmission system operating between a data terminal and a data transmission device for data telecommunication

A method for controlling data transmission in a wireless V.24 data transmission system operating between a data terminal and a data transmission device. The data transmission system has a first data transmission apparatus connected to a data terminal by means of a V.24 cable and a second data transmission apparatus also connected to a data transmission device by means of a V.24 cable. An air interface may be used for wireless telecommunications in order to control transmission of control commands or control information for the data transmission device from the data terminal to the data transmission device. Recognizability of control commands or control information for the data transmission device is ensured, once a time-critical control command is made known in the data transmission apparatuses. After transmission has been completed on the transmission path between the first data transmission apparatus and the data terminal, the time sequence of the transmission of the control command on the transmission path between the second data transmission apparatus and the data transmission device is identically reconstructed, despite any asynchronous data transmission caused by the air interface in the wireless V.24 data transmission system.

In a wireless telecommunication system, for example a DECT/GAP system, under the control jurisdiction of a first telecommunication apparatus of the telecommunication system control mechanisms (i.e. messages, information elements and procedures) of a standard protocol (e.g. a protocol according to the DECT/GAP standard) are activated for the execution of a special protocol, which serve for the exchange of additional items of information between the first telecommunication apparatus and a second telecommunication apparatus of the telecommunication system.

Process and arrangement for executing protocols between telecommunications devices in wireless telecommunications systems

In a wireless V.24 data transmission system operating between a data terminal and a data transmission device for data telecommunication having a first data transmission apparatus connected to the data terminal by means of a V.24 cable and a second data transmission apparatus connected to the data terminal by means of a V.24 cable, the apparatus may in turn be connected for wireless communication by means of an air interface. In order to control data transmission in such a way that baud rate changes can be easily detected, the baud rate is detected by the first data transmission apparatus while the autobauding function is activated in the first data transmission apparatus and in the data transmission device. The baud rate is transmitted by signaling to the second data transmission apparatus and is regulated therein parallel to the command data (AT commands) to be sent.

In a cordless telecommunications system with assured interoperability of cordless telecommunications applications, in particular a GAP-specific DECT system, having a cordless base station and having cordless mobile parts which are capable of telecommunication with the cordless base station via a radio interface wherein the number of mobile points exceeds the number of telecommunications channels which are available in parallel at the cordless base station, collective/group calls being possible while the interoperability of the cordless telecommunications applications remains ensured, mixed operation is implemented including a connection-based virtual-collective/group call and a connectionless collective/group call.

In order to be able to control the setting up of telecommunication connections efficiently and reliably in telecommunication subsystems serving as local message transmission loops of telecomunication systems and having network terminations which differ with regard to the transmission channel requirements, a first network termination specifies explicitly, for example in the form of a parameter, the requested transmission channel desired by it in a connection, set-up message of the network termination to the remote station in the telecommunication subsystem.
