Data adapter or communication devices for the telecommunication of useful data, particularly of packet data and/or voice data
View Patent ↗To improve 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, a data adapter (DA 1, DA 2 ) is allocated both a fixed-part-specific air interface architecture (DÜM, STM, PKM 2 ) for implementing the prescribed air interface protocol, and the air interface architectures associated with the data adapter (DA 1, DA 2 ) 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 (KE 1, KE 2 ) is connected to the data adapter (DA 1, DA 2 ).
1. A first data adapter for communication devices for telecommunication of useful data, said first data adapter comprising:
a data interface supporting a link to the communication devices;
a data transmission part for wireless transmissions and reception of the useful data based on a prescribed air interface protocol; and
a controller connected to both the data interface and the data transmission part and to which program modules are allocated,
the controller and program modules operating to effect two-way transmission of the useful data,
wherein the data interface is used based on an appropriate interface protocol and the data transmission part is used based on the prescribed air interface protocol,
the controller
including first protocol modules for transmission in a downlink direction and for reception in an uplink direction, by which the first data adapter is operated in a first control state in a fixed part-mode, and
including second protocol modules for reception in the downlink direction and for transmission in the uplink direction, by which the first data adapter is operated in a second control state in a portable part-mode,
the controller activating one of the first protocol modules and the second protocol modules based what type of communication device is allocated to the first data adapter and the manner of telecommunication of the associated useful data;
whereby when the first data adapter is operated in the fixed part-mode, at least a second data adapter operated in the portable part-mode can be connected to the first data adapter.
2. A data adapter as claimed in claim 1 , wherein the controller operates in a first control state in which the data interface and the first protocol modules are connected, and operates in a second control state in which the data interface and the second protocol modules are connected.
3. A data adapter as claimed in claim 2 , wherein the controller may be controlled to adopt the first and second control states through operating procedures on the particular communication device.
4. A data adapter as claimed in claim 2 , wherein the controller may be controlled to adopt the first and second control states through operating procedures on the data adapter.
5. A data adapter as claimed in claim 1 , wherein the program modules are arranged in the particular communication device.
6. A data adapter as claimed in claim 1 , wherein the program modules are arranged in the data adapter.
7. A data adapter as claimed in claim 1 , wherein the data adapter is configured as a card, wherein the card may be integrated in the particular communication device.
8. A data adapter as claimed in claim 1 , wherein the data adapter is connected to the particular communication device as a peripheral.
9. A data adapter as claimed in claim 1 , wherein the data interface is selected from a group consisting of an RS232 interface, a V.24 interface, and a USB interface.
10. A data adapter as claimed in claim 1 , wherein the air interface protocol is selected from a group consisting of a PHS protocol, a GSM protocol, and a UMTS protocol for a paired and unpaired frequency range.
11. A data adapter as claimed in claim 1 , wherein the communication devices are selected from a group consisting of a personal computer, a notebook computer, a PDA unit, a fax machine, a printer, a line-connected telephone, and a server-controlled local area network.
12. A data adapter as claimed in claim 7 , wherein the card is a PCMCIA card.
13. A data adapter as claimed in claim 1 , wherein the air interface protocol is a DECT protocol.
14. A first data adapter for communication devices for telecommunication of useful data, said data adapter comprising:
a data interface supporting a link to the communication devices;
a data transmission part for wireless transmissions and reception of the useful data based on a DECT interface protocol; and
a controller connected to both the data interface and the data transmission part and to which program modules are allocated,
the controller and program modules operating to effect two-way transmission of the useful data,
wherein the data interface is used based on an appropriate DECT interface protocol and the data transmission part is used based on the prescribed DECT interface protocol, and
wherein the controller is configured to activate a protocol module selected from the set consisting of first protocol modules and second protocol modules,
said first protocol modules being for transmission in a downlink direction and for reception in an uplink direction, by which the data adapter is operated in a first control state in a fixed part-mode, and
said second protocol modules being for reception in the downlink direction and for transmission in the uplink direction, by which the data adapter is operated in a second control state in a portable part-mode.
