Abstract
The aim of the invention is to improve the teletransmission of useful data, especially of packet and/or voice data by means of communications devices with regard to easy use, for example, versatile, universal application and use, and to improve location-independence (mobility). To these ends, both a fixed part-specific common air interface architecture (DUM, STM, PKM1) for carrying out a given common air interface protocol and a mobile part-specific common air interface architecture (DUM, STM, PKM2) for carrying out the given common air interface protocol are assigned to a data adapter (DA1, DA2). The common air interface architectures assigned to the data adapter (DA1, DA2) are activated according to the particular application, i.e. which scenario should be realized for the teletransmission of useful data and especially which communications device (KE1, KE2) is connected to the data adapter (DA1, DA2).
Description
Description Data adapter for communication devices for the telecommunication of useful data, particularly of packet data and/or voice data The invention relates to a data adapter for communication devices for the telecommunication of useful data, particularly of packet data and/or voice data, in accordance with the precharacterizing clause of patent claim 1.
For the telecommunication of useful data - transmitting and receiving, for example, voice data and/or packet data over relatively long distances - between physically separate data terminals (communication devices) in the form of data sources and data sinks in a telecommunication network (scenario for the telecommunication of useful data), special data adapters are used which link the data terminals to the telecommunication network such that the useful data can be transmitted on the network-specific transmission link.
The publication "it + ti - Informationstechnik and technische Informatik [Information Technology and Information Systems]" 37 (February 1995), No. 1, R. Oldenbourg Verlag [publishers], pages 21 to 28, presents, under the heading "Mobile Computing - Komponenten, Systemintegration, Anwendungen [Mobile Computing - Components, System Integration, Applications]", a scenario for the telecommunication of useful data, particularly packet data.
For the telecommunication of useful data, particularly packet data, the data adapters used to date for communication devices, for example in the form of personal computers, Notebooks, PDA units (Personal Digital Assistant), have primarily been modems and PCMCIA cards (Personal Computer Memory Card International Association).
GR 98 P 1386 - la -While the modems can be used to link the aforementioned communication devices essentially to line-connected telecommunication networks, the PCMCIA cards can also be used to link the devices to wireless telecommunication networks. Thus, a PCMCIA card and a GSM handset (GSM mobile phone) can be used to link a Notebook to the GSM network in a known manner, for example. Although such an equipment arrangement can be used independently of location, it cannot be used for different user-specific application instances. Thus, for example, it is not possible for a dedicated user-specific network for the telecommunication of useful data to be installed by the user independently of the telecommunication network.

GR 98 P 1386 - 2a -Furthermore, DE-40 26 426 A1 discloses a system for data transmission in which one or more personal computers and peripherals, particularly printers, can be connected to one another within a space wirelessly, specifically with selective access over the radio path for the purposes of data transmission.
In addition, DE-43 20 047 A1 discloses a cordless telephone which, to extend its use to any other desired applications, has at least one mobile part which is supplemented by means of an additional interface, which is inverse to the network, to form a cordless telephone line unit (telephone outlet). Such an access capability enables virtually all the usual terminals, such as telephones, videotex, modem, fax, answering machine, telecommanding and teleaction devices and ancillary devices, to be operated directly on a mobile and wireless basis.
The object on which the invention is based is that of improving the operating convenience - e.g.
versatile, universal application and use - and location-independence (mobility) of the telecommunication of useful data, particularly packet data and/or voice data, using communication devices.
This object is achieved on the basis of the data adapter defined in the precharacterizing clause of patent claim 1, by the features specified in the characterizing clause of patent claim 1.
The idea on which the invention is based is that of allocating to a data adapter for communication devices for the telecommunication of useful data, particularly of packet data and/or voice data, both a fixed-part-specific air interface architecture for implementing (processing) a prescribed air interface protocol and a mobile-part-specific air interface architecture for implementing (processing) the prescribed air interface protocol, and manually and/or automatically activating the air interface architectures associated with the data adapter 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 is connected to the data adapter.
This makes it possible, in particular, for example, to produce different scenarios in the office and home environment. Thus, for example, it is possible to perform telecommunication of useful data, particularly voice data and/or packet data, between personal computers, Notebooks, PDA units etc. used on a geographically mobile basis without any cable installation. Furthermore, it is possible for a cordless link to be produced between a personal computer, a Notebook, a PDA unit etc. and the telecommunication network or the Internet. Hence, this means that in future it will be possible to "surf" the Internet from the garden using a Notebook - independently of a telephone outlet and at fixed-network charges, not, as previously, at mobile-network charges. Depending on the modem, the data adapter provided with a data interface in the form of a V.24 interface, for example, to the communication device permits data transmission rates of, for example, up to 64 kBit/s, the transmission rate of an ISDN
useful data channel.
In this context, the decision regarding which of the two air interface architectures is used is preferably made by the user of the data adapter by performing operating procedures on the data adapter or on the communication device, in accordance with claims 3 and 4. Suitable operating procedures in this case are, preferably, key actuations and/or corresponding voice inputs.
In accordance with claims 5 and 6, the program modules required for operating the data adapter can be allocated either to the data adapter itself or to the communication device. tnlhereas the practice according to claim 5 is suitable for personal computers, Notebooks, PDA units etc., the practice according to claim 6 is advantageous for printers and fax machines.
Various advantageous embodiments of the data adapter are specified in accordance with claims 7 and 8.
Further advantageous developments of the invention are specified in the remaining patent claims.
An illustrative embodiment of the invention is explained with reference to the FIGURE.
The single FIGURE shows the basic structure, based on the OSI/ISO layer model jcf. (1):

publication ETS 300175-1_9, October 1992), of a data adapter DA, for example in the form of a PCMCIA card or line unit, for communication devices KE for the telecommunication of useful data, particularly voice data and/or packet data, using an application instance (scenario for the telecommunication of voice data and/or packet data) in which a first communication device KE1, for example in the form of a personal computer (PC), using a first data adapter (DA1), for example in the form of a DECT data adapter, and a second communication device KE2, for example in the form of a personal computer (PC), using a second data adapter DA2, for example in the form of a DECT data adapter, are wirelessly connected to one another for the telecommunication of useful data, e.g. packet data.
The two pieces of equipment (device and data adapter) are arranged at a distance apart, for example, which is such that the transmission range which is specified in the DECT standard or is possible, in principle, on the basis of the DECT standard is not exceeded.
Furthermore, the two units are preferably not in the radio range of a DECT base station for which the units have access authorization. To enable data to be interchanged between the two units, one data adapter from the two data adapters DA1, DA2 - e.g. the first data adapter DA1 - is operated in a mode specific to a DECT fixed part, the FP mode (Fixed Part), or is controlled so as to adopt a first control state STZ1, and the other data adapter - e.g. the second data adapter DA2 - is operated in a mode specific to a DECT
GR 98 P 1386 - 5a -mobile part, the PP mode (Portable Part), or is controlled so as to adopt a second control state STZ2.
To this end, the data adapter DA1, DA2 contains a data interface DSS which, by way of example, is in the form of a serial V.24 interface, an RS232 interface or a USB interface (Universal Serial Bus) and connects the data adapter DA1, DA2 to the respective communication device KE1, KE2. In addition, the data adapter DA1, DA2 contains control means STM and data transmission means DUM. The data transmission means DUM
correspond, on the basis of the ISO/OSI layer model, to the physical medium and contain the hardware required for telecommunication of the useful data in the data adapter DA1, DA2. The control means STM contain the software required for telecommunication of the useful data in the data adapter DA1, DA2. Thus, the control means STM contain an Interworking Unit layer (IWU
layer) IWUS, a first protocol module PKM1, in the form of a DECT FP protocol stack, a second protocol module PKM2, in the form of a DECT PP protocol stack, a physical layer (PH layer) PHS and possibly a program module PGM. Since this program module PGM may alternatively also be contained in the communication device KE1, KE2, the program module PGM is shown in dots in the FIGURE.
The IWU layer IWUS is connected, on the one hand, to the data interface DSS, and, on the other hand, is connected to the first protocol module PKM1 or to the second protocol module PKM2 - depending on the mode in which the data adapter DA1, DA2 is to be operated or on which control state STZl, STZ2 has been set, e.g. using an FP/PP switch. The protocol modules PKM1, PKM2 are in turn connected to the PH layer PHS, which, for its part, is connected to the data transmission means DUM.
The program module PGM can be used to control (configure) the data adapter DA1, DA2, e.g. using the FP/PP switch, such that the data adapter DA1, DA2 is in the form of or functions as a base station or a mobile part. If one data adapter is configured as a base station and the other data adapter is configured as a mobile part, then the mobile part can register with the base station via the air interface using the known DECT registration procedures. The program module PGM can thus also be used to initialize and control the DECT registration procedures. Once registration is complete, wireless telecommunication of useful data between the communication devices KE1, KE2 is possible.
to In addition or as alternatives to the scenario described above for the telecommunication of voice data and/or packet data, further scenarios are possible. The scenario below is representative of this multiplicity of scenarios:
A communication device, e.g. a Notebook, is connected, on the one hand, for example, to a local area network with a network server (LAN) by means of an LAN card (stationary operation of the Notebook), and, on the other hand, is connected to a data adapter. If the data adapter is operated in FP mode in this case, i.e. a base station is connected to the local area network, then another communication device, e.g. a telephone, connected to a data adapter operated in PP
mode or a normal DECT mobile part can be used to perform telecommunication of voice data via the communication device connected to the local area network, either by means of "interworking" from the local area network (LAN) to the ISDN network or as Internet telephony.
However, if the Notebook is not connected to the local area network (LAN) (mobile operation of the Notebook), the data a3apter connected to the Notebook can be changed over from FP mode to PP mode. If another base station is connected to the local area network (LAN) indirectly or directly, then the Notebook can be used to perform telecommunication of packet data for the purpose of printer or LAN server access operations (keyword: Internet sessions).
For the telecommunication of useful data - transmitting and receiving, for example, voice data and/or packet data over relatively long distances - between physically separate data terminals (communication devices) in the form of data sources and data sinks in a telecommunication network (scenario for the telecommunication of useful data), special data adapters are used which link the data terminals to the telecommunication network such that the useful data can be transmitted on the network-specific transmission link.
