Abstract

A method for the transmission of data using radio transmission systems between transmitter/receiver stations is provided, and a computer for the allocation of radio transmission systems for the transmission of data between transmitter/receiver stations is provided, which serve to select radio transmission systems dynamically, for a communication from at least one transmitter/receiver station, on the basis of a subscriber profile, a location of the one transmitter/receiver station, and/or a speed of the transmitter/receiver station, in order to transmit data between transmitter/receiver stations. A computer in a switching device calculates which radio transmission system best meets the criteria. During a data transmission, it is possible to switch automatically to a further radio transmission system if the transmission quality of the radio transmission system currently being used declines.

Claims

1. A method for transmission of data using radio transmission systems between transmitter/receiver stations, comprising:

receiving transmissions from at least two radio transmission systems simultaneously at one location, wherein a radio transmission system including at least one downlink and at least one uplink is operated;

operating at least one transmitter/receiver station in mobile fashion;

establishing a connection between the transmitter/receiver stations by the radio transmission system including at least one downlink and at least one uplink;

ascertaining a quantity of data for transmission by a computer after establishment of the connection between the transmitter/receiver stations, wherein the computer is operated in one transmitter/receiver station; and

switching over, by the computer, in the context of a subscriber profile, one of entirely and partially to another radio transmission system having a high transfer rate if at least one of expected cost and speed of the mobile transmitter/receiver station permits.

2. The method according to claim 1, further comprising:

transmitting data concerning a transmission quality and the subscriber profile to the computer from the mobile transmitter/receiver station.

3. The method according to claim 2, wherein the data concerning the transmission quality and the subscriber profile are transmitted via the uplink.

4. The method according to claim 3, further comprising:

transmitting, on the basis of the subscriber profile, at least one of data concerning a location of the mobile transmitter/receiver station and data concerning a speed of the mobile transmitter/receiver station.

5. The method according to claim 4, further comprising:

ascertaining the transmission quality on the basis of at least one of a signal field strength and an error rate of received data.

6. The method according to claim 4, further comprising:

ascertaining the location of the mobile transmitter/receiver station by using a localization device.

7. The method according to claim 6, wherein the subscriber profile indicates a service quality that is to be made available, devices that are included in the respective transmitter/receiver station, and the maximum cost that is permissible for the transmission of data.

8. The method according to claim 7, wherein the speed of the mobile transmitter/receiver station is ascertained by using one of at least one sensor and radio signals.

9. The method according to claim 8, further comprising the step of:

transferring the data to a further radio transmission system, when a criterion requiring such action is satisfied.

10. A computer-based system for allocation of radio transmission systems for a transmission of data between transmitter/receiver stations, comprising:

an arrangement for selecting from at least two radio transmission systems;

an arrangement for receiving data from at least one mobile transmitter/receiver station, wherein the data is received via a subscriber profile; and

an arrangement for switching over, as a function of a quantity of data to be transmitted, to a radio transmission system having a higher transfer rate if an expected cost and a speed of the mobile transmitter/receiver station permit;

wherein the computer-based system is an element of a switching device connected to a communication network.
