Abstract

Data sets are transmitted to mobile terminals, which are connected by a radio network to a data server connected to a data network, wherein the data server is configured to transmit the data sets via the radio network to terminals located in a radio cell of the radio network as a broadcast signal or optionally as an individual signal directed specifically to one or more terminals, wherein a total signal emitted into the radio cell contains a corresponding broadcast signal part and a corresponding individual signal part. In one embodiment, a user profile is associated with each of the terminals identified in the radio cell and the content of the data sets transmitted in the broadcast signal part in accordance with a determined broadcast signal part factor is compiled in accordance with the information stored in the user profiles.

Claims

1. A method for transmitting data sets to mobile terminals which are connected via a radio network to a data server connected to a data network, wherein the data server is configured to transmit the data sets via the radio network to terminals located in a radio cell of the radio network as a broadcast signal or optionally as an individual signal specifically directed to one or more terminals, wherein a total signal sent out to the radio cell contains a corresponding broadcast signal part and a corresponding individual signal part, wherein the method comprises the acts of:

transmitting, via a recognition system independent of the radio network, an item of recognition information by each of a plurality of terminals; and

receiving, by the data server, one or more of the respectively transmitted items of recognition information via the independent recognition system;

identifying, by the data server, one or more of the plurality of terminals as being located within the radio cell by virtue of receiving respective items of recognition information from such one or more terminals via the independent recognition system;

determining a preferred broadcast signal part factor for the total signal by the data server on the basis of a data requirement requested by the one or more terminals identified within the radio cell; and

transmitting a first component of the data sets in the broadcast signal part of the total signal and a second component of the data sets in the individual signal part of the total signal from the data server to the one or more terminals,

wherein the broadcast signal part of the total signal transmitted to the one or more terminals is determined based on the determined broadcast signal part factor preferred, and

wherein the one or more terminals identified as being in the radio cell are, in each case, allocated a user profile and the content of the data sets transmitted in the broadcast signal part is assembled based on the information deposited in the user profiles.

2. The method as claimed in claim 1, wherein the user profiles are obtained by the data server via the data network.

3. The method as claimed in claim 1, wherein the user profiles are generated by the data server.

4. The method of claim 1, wherein the preferred broadcast signal part factor corresponds to those time intervals of the total signal which are available for a broadcast transmission by virtue of not being required for transmission of signals that have to be sent out mandatorily as individual signals.
