In a digital Time Division Multiple Access radio communications network that includes a number of Base Transceiver Stations, and several Mobile Stations, a handover can be accomplished so that the parameters required in identifying a Mobile Station, and the frequency data, the data of the time interval to be used, as well as the frame number data of the channel are given to a new Base Transceiver Station to which a Mobile Station will be moved. The new Base Transceiver Station is tuned to listen to the channel determined by the data it received. The former Base Station transmits a handover command to the Mobile Station containing the frequency data, the data of the time interval to be used, as well as the frame number data of the channel to which the new Base Station has moved. After the command the Mobile Station turns the trafficing directly to said channel. The timing measurements between the Base Station and the Mobile Station are not required and any tuning correction is carried out by the channel equalizer.
