In a wireless communication system having at least first and second radio stations located at a network end and connected to a core network, the first radio station receives a registration message from a user station to initially register the user station in a radio station located at the network end, after the user station has been switched on. Subsequently, communication takes place between the core network and the user station. Signaling messages that are to be sent from the core network to the user station are transmitted, at least at the beginning of the communication between the core network and the user station, from the core network to the second radio station, then from the second radio station to the first radio station or another radio station located at the network end, and from the first radio station (or the other radio station) directly to the user station.
