In a GSM mobile radio network having at least one base station controller and a first base station, at least one first frequency channel is made available within a frequency band between the first base station and the mobile stations in order to transmit data and to transmit signaling information. According to the invention, the first base station additionally makes available a second broadband frequency channel with a TD/CDMA transmission method. After a connection has been set up in the first or second frequency channel, a handover of the connection to the respective other frequency channel is carried out by the base station controller without a second base station being selected.
