Verfahren zur drahtlosen Funkkommunikation zwischen einer ortsfesten und einer mobilen Funkvorrichtung

摘要

The invention relates to a method for establishing a wireless radio connection between one of a number of radio base devices (BS-A, BS-B, BS-C) and an additional radio device (MMS). The additional radio device exchanges radio signals with the radio base device via a radio connection inside a determined spatial area (cell(A; B; C)), whereby a set of n transmission frequencies (fi,1,..., fi,n; n=A,B,C) from a total of N usable transmission frequencies (f1,...,fN) is respectively allocated to each radio base device (BS-A, BS-B, BS-C) in order to both transmit required first data for preparing the radio connection, especially base and signalizing data, as well as additional second data. In addition, the transmission frequency is changed during the transmission of the second data between the transmission frequencies provided for transmitting said second data. The respectively used transmission frequency between all n transmission frequencies (fi,1,..., fi,n) of the allocated set is then changed during the transmission of both the first as well as the second data. The allocation of the respective frequencies for a cell or subcell requires as little planning as possible.
