The invention claimed is: 1. A method for transmitting data between a base station and at least one terminal via a radio connection with a timeslot structure in a radio communications system, comprising: determining how a speed of the terminal relative to an external disturbance of the radio connection varies with time; selectively inserting measurement data for determining transmission characteristics of the radio connection, the measurement data being selectively inserted into the timeslot structure depending on the variation with time of the speed of the terminal relative to the external disturbance of the radio connection; wherein the measurement data is selectively inserted such that an amount of measurement data inserted is reduced when the variation with time of the speed of the terminal relative to the external disturbance of the radio connection is reduced. 2. The method according to claim 1, wherein a property of the radio connection comprises the extent to which the signal quality of the radio connection varies with time. 3. The method according to claim 2, wherein the measurement data is selectively inserted such that an amount of measurement data inserted is reduced when the variation with time of the speed of the terminal relative to the external disturbance of the radio connection is relatively stable. 4. A method for transmitting data between a base station and at least one terminal via a radio connection with a timeslot structure in a radio communications system comprising: determining a variation with time of a speed of the terminal relative to an external disturbance of the radio connection; and selectively inserting measurement data for determining transmission characteristics into the timeslot structure, the insertion of the measurement data into the timeslot structure depending on the variation with time of the speed of the terminal relative to the external disturbance of the radio connection, wherein the measurement data are inserted into an increasing number of timeslots with an increasing variation with time of the speed of the terminal relative to the external disturbance of the radio connection. 5. The method of claim 4, wherein, a number of channels are provided for the radio connection and the determination of the transmission characteristics, and the measurement data and payload data are transmitted on a same channel. 6. The method of claim 4, wherein, a number of channels are provided for the radio connection and the determination of the transmission characteristics, and the insertion of the measurement data take place on different channels. 7. The method of claim 4, wherein the determination of the variation with time of the speed of the terminal relative to the external disturbance of the radio connection depends on the variation with time, of factors that influence the transmission characteristics. 8. The method of claim 7, wherein the measurement data are inserted into the timeslot structure in dependence on external disturbances of the radio connection between the base station and the terminal. 9. The method of claim 7, wherein the measurement data are inserted into the timeslot structure immediately after a data transmission speed between the base station and the terminal exceeds a predetermined data transmission speed. 10. The method of claim 4, wherein the measurement data are always inserted into a predetermined number of timeslots at the beginning of a radio connection. 11. The method of claim 4, wherein when the measurement data are inserted into the timeslots, the measurement data are inserted instead of payload data or signaling data. 12. The method of claim 4, wherein, the measurement data are inserted into the timeslots as a preamble or midamble. 13. A method for transmitting data between a base station and at least one terminal via a radio connection with a timeslot structure in a radio communications system comprising: determining a variation with time of a speed of the terminal relative to an external disturbance of the radio connection; and selectively inserting measurement data for determining transmission characteristics into the timeslot structure, the insertion of the measurement data into the timeslot structure depending on the variation with time of the speed of the terminal relative to the external disturbance of the radio connection, wherein the measurement data are inserted into a decreasing number of timeslots with a decreasing variation with time of the speed of the terminal relative to the external disturbance of the radio connection. 14. A transmitter to transmit data between a base station and at least one terminal via a radio connection with a timeslot structure, comprising: a device to determine how a speed of the terminal relative to an external disturbance of the radio connection varies with time; and a device to selectively insert measurement data for determining transmission characteristics of the radio connection, the measurement data being selectively inserted into the timeslot structure depending on the variation with time of the speed of the terminal relative to the external disturbance of the radio connection, wherein the measurement data are inserted into an increasing number of timeslots with an increasing variation with time of the speed of the terminal relative to the external disturbance of the radio connection. 15. A radio communications system comprising: a base station; at least one terminal; a radio connection to carry data within a timeslot structure; and a transmitter to transmit the data, comprising: a device to determine how a speed of the terminal relative to an external disturbance of the radio connection varies with time; and a device to selectively insert measurement data for determining transmission characteristics of the radio connection, the measurement data being selectively inserted into the timeslot structure depending on the variation with time of the speed of the terminal relative to the external disturbance of the radio connection, wherein the measurement data are inserted into an increasing number of timeslots with an increasing variation with time of the speed of the terminal relative to the external disturbance of the radio connection. 16. A base station to transmit data to at least one terminal via a radio connection with a timeslot structure, comprising: a device to determine how a speed of the terminal relative to an external disturbance of the radio connection varies with time; and a device to selectively insert measurement data for determining transmission characteristics of the radio connection, the measurement data being selectively inserted into the timeslot structure depending on the variation with time of the speed of the terminal relative to the external disturbance of the radio connection, wherein the measurement data are inserted into an increasing number of timeslots with an increasing variation with time of the speed of the terminal relative to the external disturbance of the radio connection. 17. The base station as claimed in claim 16, wherein the device to determine receives the measurement data from the terminal.
